哈菲利电源变压器诊断仪FRA 5310 Sweep频率响应分析器说明书
FRA 5310Sweep Frequency Response Analyser for Power Transformer DiagnosisThe FRA 5310 Sweep Frequency Response Analyser detects transformer winding movements and mechanical failures due to mechanical shock, transportation or short circuits.APPLICATIONMany dielectric and mechanical failures in large power transformers are preceded by mechanical changes in the winding structure. These changes, or displacements in the winding, may be the result of:⏹Transportation damage occurring between themanufacturer and the final location⏹Short circuit forces imposed on the windingsresulting from a low impedance fault occurring close to the transformer⏹Natural effects of aging on the insulatingstructures used to support the windingsDetection of these displacements ahead of a dielectric failure can reduce unplanned maintenance costs, and provide the possibility to improve system reliability by preventing outages. Additionally, when damage is discovered, repairs may be targeted to a specific phase winding. METHODThe corresponding HF circuit of a transformer winding is a complex R-L-C-network. The measured frequency response (transfer function) of this network is unique like a fingerprint. Changes in the winding geometry will be reflected by deviations between repeated measurements. Even small winding movements or distortions will cause legible changes in the measured transfer function, which is clearly detectable. Deviations can be caused by short-circuited turns, open windings, mechanical damage to windings or core, loose turns, faulty clamps, etc.DESIGNThe FRA 5310 software and the large touch-screen interface guarantee a very easy-to-use instrument. Load measurements, set configurations, obtain connecting information, repeat previous measurements and do comparisons just on a fingertip. Integrated analysis tools, reporting capability and additional PC software complete this advanced Sweep Frequency Response Analyser.FEATURES AND BENEFITS⏹High measurement reliability and reproducibilitydue to active probes design and a clear definedconnection and grounding technique⏹High signal-to-noise ratio due to output voltage up to12 Vpeak-peak at 50 Ω (24 Vpeak-peak at 1 MΩ)⏹Automatic Interpretation according to ChineseStandard DL / T 911 - 2004⏹Ease of use due to automated Windows test softwareand large color touch screen interface and remote startbutton⏹Rugged, lightweight and small all-in-one field design ⏹Measuring modes (amplitude & phase):▪Transfer Voltage Function U1/U2 (f)▪Impedance Function U1/I2 (f) 1981Previously stored curves are accessed using the History tab sheet, where information can be edited and updated at a later date.Automatic Test Setting (Sequence)Analysis page with limits set according to the standards A complete transformer test measurement list (sequence) can be predefined and executed automatically when required, making it simple to repeat a previous fingerprint measurement, even if the operator has no previous knowledge of the setup.ANALYSIS TOOLSThe analysis system allows multiple stored measurements to be loaded for detailed analysis, comparison, verification, reporting, etc.The measured transfer function curves can be displayed as Magnitude [dB], Phase [°], Impedance [ ] , Admittance [S] and Ratio.Additional comments can be stored with the single analysis displays so expert interpretation andassessments, further test instructions, etc can be included. Various display tools are easily accessible from the touch screen to allow simple analysis: Zoom-in and -out, auto scaling, linear and logarithmic scaling, curve shifting, measuring point labels, save as meta-file, printout, title editing, setup information editing, frequency band display,etc.Two frequency response curves and their difference.Cursors can easily be placed anywhere on the displayed curves giving the user information down to the last measuring point.Differences of curves with a definable limiter function can be calculated allowing parts of the curve to beweighted and highlighted to help the engineer's decision-making.Coherence between two or more curves can becalculated to give the engineer a powerful tool for the assessment and comparison of transformer transfercurves yielding valuable additional information.Transfer functions of 3 phases and their coherence.Interpretation according to Chinese Standard DL / T 911 - 2004 is supported. This interpretation is based on thecomparison of two curve, identifies slight, obvious and severe mechanical changes and differentiate between typical origins of the damage.Comparison of two transfer functions according to Chinese Standard DL / T 911- 2004.REPORT GENERATIONThe measured frequency response curves (raw data) are stored in a measuring data file together with all the related transformer nameplate data and other additional information. Reports can be created from the measured data file (raw data curves) or from any analysis data files previously created.The user can choose different report sizes from diagrams with short setup info to full reporting with all detailed setup and DUT information.Reports are automatically generated in XML- or HTML- format allowing the report file to be opened in a web browser or word processor.Data exportThe measuring files (raw data curves) are stored in XML format and can also be stored in CSV (comma-separated-values) format.They can be directly opened in Microsoft EXCEL or other spreadsheet programs where further customer specific data processing, calculation, comparison and documentation is possible.Any curve can also be stored as a picture for further use in customer specific documentation or reporting.SCOPE OF SUPPLYType 5310 Instrument in rugged shell case,Cable back pack including:▪ 2 Active Probes with 15 m double shielded cables,▪ 2 Ground Tapes 10 m,▪ 2 Ground Tape Clamps,▪User Manual, Test Certificate,▪Mains cable CD with external PC Analysis Software TECHNICAL DATAMeasurementType ActiveprobesFrequency Range 10 Hz .. 10 MHz, user definedVoltage Output max. 12 Vpeak-peak at 50 Ω,max. 24 Vpeak-peak at 1 MΩ, userdefinedInput Impedance selectable 50 Ω or 1 MΩOutput Impedance 50 ΩAccuracy ± 0.1 dB , zero calibratedFeasible accuracy: ± 0.5 dB down to -90dBDynamic range >100 dBMeasuring Points max. 2’000, user defined,logarithmicallyspaced, Protection Against short circuit, overloadData DisplayScaling Logarithmic or Linear, user defined Frequency Range 10 Hz .. 10 MHz, user definedPlot, Frequency vs. Magnitude, Impedance, Phase,Admittance, RatioControllerProcessor Celeron M, 1 GHzRAM 256MBInterfaces USB 2.0 , RS232Data Storage 40 GB Hard DiskDisplay 10.4", SVGA, Color TFTUser Interface built-in Touch ScreenGeneralOperatingTemperature0 .. +50°CStorageTemperature-20 .. +70°CRelative Humidity 10 .. 90 % non-condensingWeight Instrument 8 kg (17 lbs)DimensionsInstrument41 x 31 x 17 cm (16” x 12.2” x 7”)Remote Start Remote start button and indicator inprobeMains Universal, 90 .. 265 VAC,50 / 60 Hz, 75 VAInstrument OS Windows XP embeddedExternal PCSoftwareWindows 98 / 2000 / XPOrder code FRA 5310 No. 3490047Europe, Asia, South & Central America, Australia Haefely Test AG Birsstrasse 3004052 BaselSwitzerland☎ + 41 61 373 4111+ 41 61 373 4912****************China (Sales & Service Office)Haefely Test AG – Beijing Office8-1-602, Fortune StreetNo. 67, Chaoyang Road, Chaoyang DistrictBeijing, 100025P.

They are designed and manufactured to meet a high degree of reliability (lifetime more than 15 years) under normal …commercial“ application conditions. Products dedicated for automotive and H-Rel applications are specifically identified for these applications. If you intend to use these …commercial“ products for airborne, space or critical transport applications, nuclear power control, medical devices with a direct impact on human life, or other applications which require an exceptionally high degree of reliability or safety, please contact the manufacturer.Electrostatic SensitivityCrystal oscillators are electrostatic sensitive devices. Proper handling according to the established ESD handling rules as in IEC 61340-5-1 and EN 100015-1 is mandatory to avoid degradations of the oscillator performance due to damages of the internal circuitry by electrostatics. If not otherwise stated, our oscillators meet the requirements of the Human Body Model (HBM) according to JESD22-A114F.HandlingExcessive mechanical shocks during handling as well as manual and automatic assembly have to be avoided. If the oscillator was unintentionally dropped or otherwise subject to strong shocks, please verify that the electrical function is still within specification.Improper handling may also detoriate the coplanarity of bended leads of SMD components. SolderingOscillators can be processed using conventional soldering processes such as wave soldering, convection, infrared, and vapour phase reflow soldering under normal conditions. Solderability is guaranteed for one year storage under normal climatic conditions (+5°C to +35°C @ 40% to 75% relative humidity), however typically sufficient solderability –depending on the process – is maintained also for longer time periods. In cases of doubt, components older than one year should undergo a sample solderability test.The recommended reflow solder profile for SMT componets is according IPC/JEDEC J-STD-020 (latest revision)SMD oscillators must be on the top side of the PCB during the reflow process.After reflow soldering the frequency of the products may have shifted several ppm, which relaxes after several hours or days, depending on the products. For details please contact the manufacturer.CleaningCleaning is only allowed for hermetically sealed oscillators. Devices with non hermetical enclosures (e.g. with trimmer holes) shall not be cleaned by soaking or in vapour, because residues from the cleaning process may penetrate into the interior, and degrade the performance.Our products are laser marked. The marking of our oscillators is resistant to usual solvents, such as given in IEC 60068-2-45 Test XA. For applicable test conditions see IEC 60679-1.Ultrasonic cleaning is usually not harmful to oscillators at ultrasonic frequencies of 20kHz at the sound intensities conventional in industry. Sensitive devices may suffer mechanical damage if subjected to 40kHz ultrasound at high sound pressure. In cases of doubt, please conduct tests under practical conditions with the oscillators mounted on the PC board.Hermetical SealIf the device is specified as hermetically sealed, it meets the requirements of IEC 60679-1, i.e. for enclosures with a volume smaller than 4000mm³ the leak rate is below 5*10-8 bar cm3/s, for larger enclosures it is below 1*10-6 bar c bar cm3/s, tested according to IEC 60068-2-17 Test Qk.Glass feed-throughs may be damaged as a result of mechanical overload, such as bending the connection leads or cutting them with an unappropriated tool. In order to avoid microcracking, the wire must be held fixed in position by a pressure pad between glass feed-through and the bending point during the bending process. Check: there should be no damaged edges on the glass feed-through after the bending.Tape & ReelThe packing in tape and reel is according to IEC 60286-3.Details see tape & reel data sheets.QualificationVectron products are undergoing regular qualification/reliability tests as per product family definition. Results are available upon request. Customer specific qualification tests are subject to agreement.If not otherwise stated, the product qualifications are performed according to IEC 60679-5 or other valid industry standards.ScreeningOur oscillators are 100% tested, and all key manufacturing processes are controlled by Statistical Process Control (SPC). Additional screening is therefore usually not required.On request, we can perform screening tests according to MIL-PRF-55310, class B for discrete or hybrid constructions of commercial (COTS) products. For special requirements see the High Reliability Clock section.Demounting/Desoldering of Ocsillator device for analysis:The removal or desoldering of oscillators from customer application after SMT process may cause damage to the device if not handeld appropriately. It may lead to parametric change such as frequency shift (like OCXO: up to +/- 200 ppb) . It is utmost important to minimize the direct heat exposure to the device in order to avoid such effects. Use of hot air gun for desoldering should be avoided.A mechanical stress could also destroy the part, if exposed to excessive mechanical shock after removal process. Appropriate shock protection & ESD designated packaging must be used to avoid any external mechanical shock for FA return process.In general, the products* withstand the tests listed in the following Table 1, which are based on valid industry standards.*Additional note: Test conditions could vary for different product families and individual product specifications depending on the customer as well as product requirements.Recommended Environmental Test ConditionsTable 1。

通信电子线路重点总结
通信电子线路重点总结第一章1、一个完整的通信系统应包括信息源、发送设备、信道、接收设备和收信装置五部分。
2、只有当天线的尺寸大到可以与信号波长相比拟时,天线才具有较高的辐射效率。
这也是为什么把低频的调制信号调制到较高的载频上的原因之一。
3、调制使幅度变化的称调幅,是频率变化的称调频,使相位变化的称调相。
4、解调就是在接收信号的一方,从收到的已调信号中把调制信号恢复出来。
调幅波的解调称检波,调频波的解调叫鉴频。
第二章1、小信号调谐放大器是一种最常见的选频放大器,即有选择地对某一频率的信号进行放大的放大器。
它是构成无线电通信设备的主要电路,其作用是放大信道中的高频小信号。
所谓调谐,主要是指放大器的集电极负载为调谐回路。
2、调谐放大器主要由放大器和调谐回路两部分组成。
因此,调谐放大器不仅有放大作用,还有选频作用。
其选频性能通常用通频带和选择性两个指标衡量。
3、并联谐振回路01LC0L10CLCCLCL(C称为谐振回路的特性阻抗)并联谐振回路的品质因数是由回路谐振电阻与特性阻抗的比值定义的,即QR0LCR00LR00CR0回路的越大,Q值越大,阻抗特性曲线越尖锐;反之,00R0越小,Q值越小,阻抗特性曲线越平坦。
在谐振点处,电压幅值最大,当0时,回路呈现感性,电压超前电流一个相角,电压幅值减小。
当相角,电压幅值也减小。
4、谐振回路的谐振曲线分析UUm11(Q2f2)f0时,回路呈现容性,电压滞后电流一个U对于同样频偏f,Q越大,Um值越小,谐振曲线越尖锐一个无线电信号占有一定的频带宽度,无线电信号通过谐振回路不失真的条件是谐振回路的幅频特性是一常数,相频特性正比于角频率。
在无线电技术中,常把Um从1下降到U1ff2(以dB表示,从0下降到-3dB)处的两个频率1和22f0.7的范围叫做通频带,以符号B或Bf2f1f0Q表示。
即回路的通频带为选择性是谐振回路的另一个重要指标,它表示回路对通频带以外干扰信号的抑制能力。

丹东华奥电子有限公司LD209A金属接近探测器集成电路说明书
丹东华奥电子有限公司简介LD209A(替代CS209A)是一种双极性集成电路,主要用于金属检测或是接近感应。
集成电路(见方框图)包含两个片上的电流调节器,振荡器和低电平的反馈电路,峰值检波/解调电路,一个比较器和两个互补的输出端。
振荡器与外部LC 网络连接,实现振荡器振幅的可调,这主要依赖于LC 谐振的Q 值。
在低Q 条件,一个可变低电平反馈电路可以为主振荡器提供驱动。
峰值解调器能够检测振荡器包络的负极部分,并将解调波形输入到比较器中。
通过将解调器的输入与内部基准相比较,比较器确定互补输出端口的状态。
输出引脚需要连接外部负载。
.内部包含瞬变抑制电路,用来在谐振电路末端吸收负极瞬变。
LD209A 可用于汽车速度传感器电路。
