2SJ594中文资料
SAE J 594中文版
SAE J594 回复反射器中文译本-2018年6月版本文件进行了修订，以更新各种参考资料并修复小的印刷错误。
此外，删除了第7.1节“光度设计指南”，因为它不是必需的。
此外，图2的光度要求将1.5度观察角的（0,0）入射角值从6更改为7。
根据以往的历史，当原始光度表被更改为添加每入射勒克斯的最小毫坎德拉要求，以使用国际单位标准化文件时，该值被四舍五入而非四舍五舍五入。
与使用乘数转换单位的其他最小值的计算相比，这使得该特定值不正确。
这一变化很小，但应予以注意。
SI单位和英制单位之间的换算计算现已作为注释包含在内。
此外，还增加了投影仪光源CCT（相关色温）的公差，到目前为止还不存在。
此外，还添加了图1A和1B，以帮助演示测量的入射角与观察角的概念。
添加图1C是为了描述一种可接受的方法，该方法通过使用校准投影仪光源和使用分光辐射计的光纤布置来测量测试项目的反射颜色。

Over a wide range of circumstances a significant portion of the generated signal energy will have frequencies above the range of the human ear. This is the ultrasonic frequency range and may be used to detect the presence of corona or surface discharge with the advantage that audible background noise is excluded.Corona and surface discharge are localized to small areas relative to the total size of the equipment. The Biddle Cat. No. 569001 Ultrasonic Corona and Leak Detector is equipped with a highly directional horn to permit the user to localize the source of the electrical discharge while remaining at a safe distance from the electrical terminals. This directional property also increases the sensitivity of the detector and tends to exclude any ultrasonic signals not related to the test in progress. The Cat. No. 569001 is effective in locating corona on insulators, bushings, and potheads in energized circuits such as utility poles, non-enclosed switchgear, bus bars or transformers and aids in isolating multiple sources located on the equipment under test. It is also useful in checking insulation test setups for either ac or dc to determine if corona is present on the test terminals. Pinpointing such corona and demonstrating its reduction will usually result in considerable saving of testing time and assist in obtaining reliable results.The Detector is designed for easy use. It is supplied in a compact light-weight carrying case; it operates on a single transistor battery and is quickly ready for service in the field or on the test floor.In addition to detecting corona sources, the Detector is an excellent tool for locating gas leaks and other sources of ultrasound.A1INTRODUCTION (Cont’d.)When ultrasound is generated in parts of a container or assembly, the surfaces of the container usually transmit the ultrasonic sound but may not radiate effectively. For such cases the Cat. No. 569001-8 Contact Probe accessory is available. This probe makes direct contact with the surface to detect the ultrasound, similar to the action of a stethoscope. The contact probe is used to identify such problems as defective bearings or gears, or leaking steam traps. Ultrasonics can also be used to detect leaks in a sealed container before it is filled. (This can be a significant cost saving.) The container can be considered, in the general sense, as any enclosure where a leak may be damaging. For such applications, the Cat. No. 569001-7 Ultrasonic Transmitter is available. In effect, the transmitter is sealed in the enclosure or container while it is transmitting. Since ultrasonic sound will escape through remarkably small openings, the detector is used to scan the outside to locate the leak.A2Section BSAFETY PRECAUTIONSSAFETY IS THE RESPONSIBILITY OF THE USERLA SEGURIDAD ES LA RESPONSABILIDAD DEL OPERADOR Although this test set does not contain any high voltages, it is usually operated in the vicinity of high voltage apparatus. The Test Set must be used only by persons fully aware of the proper safety procedure in such locations.Further precautions are necessary because the person wearing headphones may not hear vehicular traffic or audible alarms. When such hazards exist BIDDLE Instruments recommends that the loudspeaker or meter of the Cat. No. 569001 be used in preference to the headphones.The sound produced by the headphones of the Cat. No. 569001 can reach levels approaching those that risk hearing damage, therefore, the operator must set the volume control at a sufficiently low level to prevent discomfort.BIDDLE Instruments considers it advisable for the user to become familiar with the Cat. No. 569001 prior to using it in the field.Section CRECEIVING INSTRUCTIONSWhen your BIDDLE instrument arrives, check the equipment received against the packing list to ensure that all items are present. Notify AVO International Valley Forge, PA 19485 of any shortage. Make sure all the components shown in Figure 1 are included.Examine the instrument for damage received in transit. If any damage is discovered, file a claim with the carrier at once and notify BIDDLE Instruments or its nearest authorized sales representative, giving detailed description of the damage observed.This instrument has been thoroughly tested and inspected to meet rigid inspection specifications before being shipped. It is ready for use when set up as indicated in Section E.DESCRIPTION and SPECIFICATIONSGENERALThe Biddle Cat. No. 569001 Detector consists of several interconnecting components supplied in a cushioned carrying case as shown in Figure 1. The microphone probe and the receiver make up a basic complete system. The receiver converts and amplifies the ultrasonic signals from the microphone probe to an audible loudspeaker or headphone output and also to a meter deflection. It has a single control for on-off and volume.Although the microphone probe has directional properties, a great improvement is provided by assembling it into the directional “horn” which is the key part of the system. The horn focuses sharply enough to enable the user to locate corona sources while remaining at a safe distance from the high-voltage energized apparatus. A pistol-grip holder and a peepsight provide for aiming.A rubber “sound concentrator” tube can also be attached to the microphone; this aids in locating very small ultrasound emitters of mechanical nature such as pinhole gas leaks.Two accessories are available for use with the basic detector, (see Fig. a2). One is a contact probe that replaces the microphone. When this is used, the detector acts similar to a stethoscope to detect ultrasound transmitted in solid bodies. The second accessory is an ultrasound Tone Generator; an independent unit that can be placed in an enclosure. The ultrasound generated will penetrate small openings and can be detected using the microphone pickup with the detector. CIRCUIT DESCRIPTIONThe solid state circuit operates on the hetrodyne (heat frequency) principle. The detecting microphone probe is crystal responsive to frequencies from about 35 to 45 kilohertz.The receiving circuitry amplifies the transducer probe signal and mixes it with a signal from a fixed-frequency local oscillator to produce a beat note of about 1000 Hz when the microphone is responding to a signal of 40 kilohertz. The amplified beat frequency is used to drive the internal speaker and also rectified to operate the output meter. Plugging the headphones into the circuit diverts the signal from the speaker to the headphones.DESCRIPTION AND SPECIFICATIONS (Cont’d.)The circuit is powered from a 9-volt transistor type battery. The power requirements are small enough so that the battery life is on the order of 75 hours if used intermittently.The circuit has sufficient gain available so that the sensitivity is limited only by the noise of the input stage.SPECIFICATIONS:Operating frequency .......................range35 to 45 kHz Directivity.........................................Distinguishes point sources6 inches apart at 5 feet and1 foot apart at 10 feet.

Burgess 2V6, Eveready216.or equivalent.Operating Frequency.......................Centered on 40kHz.OPERATIONPRELIIMINARYSelect any accessories to be used with the basic system (microphone probe and receiver). Fit the microphone with either the sound concentrator or the directional horn by sliding it into the mating opening. In the case of the horn, the microphone must be fully inserted into the socket and the two thumb screws tightened with the fingers to prevent the microphone from dropping out if the horn is pointed overhead. Now clip the receiver to a convenient article of clothing or hold it in your hand. Connect the microphone probe cord to the fitting marked “PROBE’ making sure to tighten the lock ring.If the headphones are to be used they are simply plugged into the jack marked “PHONE”. Turn on the set by pushing the control thumb wheel to the left. Increase the volume setting until the background noise is heard. Hold your hand about an inch or two from the horn mouth (probe mouth) and lightly rub your fingers together. This will produce a distinct output to insure that everything is operating. Now turn the receiver off.LOCATING CORONA SOURCESMake a careful survey of the apparatus to be tested and take all precautions to avoid electrical shock. Identify the high voltage terminals and suspected regions to be examined. Choose a safe location that gives a clear direct air path to the suspected area.WARNING!DO NOT APPROACH ENERGIZED APPARATUS WITH THEHORN IN HAND: IT IS AN EXCELLENT ELECTRICALCONDUCTOR!Turn on the receiver and scan the suspected area with the microphone probe by simply pointing it at the suspected regions.Corona, surface discharge or arcing will be readily identified over the background noise. If the circuit is ac the corona will be identified as a very rough sounding tone with the power frequency identifiable. The sound is similar to that produced by passing a coarse file over the edge of a 3 x 5 paper card.OPERATION (Cont’d.)If the apparatus is operating with dc, you will hear a series of popping sounds when there is an intermittent discharge. For extensive discharges the sound approaches a tone.CONTACT PROBETo use the Contact Probe, connect it to the receiver in place of the microphone. Test the system just as for the microphone except lightly rub your finger on the probe stem.WARNING!THE CONTACT PROBE IS NOT INTENDED TO PROVIDEHIGH VOLTAGE INSULATION. IT SHOULD ONLY BE USEDWHERE NO DANGER OF ELECTRIC SHOCK EXISTS.TONE GENERATORTo use the Tone Generator, move the toggle switch to the “On” position. To insure that the Tone Generator is operating, place it at least 5 feet away and listen for a tone, using the receiver with the microphone. Be sure to keep the gain setting low to avoid discomfort.Section FAPPLICATIONThe Corona and Leak Detector can be adapted to many different situations.In the case of large apparatus such as a small open air substation or a portion of a larger substation, use the microphone probe without the directional horn when making a fast general survey. To localize a source such as a particular bushing, insulator or cable pothead, use the directional horn and scan the area by aiming directly at the suspected object using the peep sight for accuracy.To investigate the interior of metal-clad switchgear, use the rubber sound concentrator and listen at openings in the structure such as door seams or ventilating openings.The Detector is useful for many other purposes beside the location of electrical discharges. The most common of such uses are:Locating leaks in pressurized communication cable.Locating leaks in air systems.Detecting the flow of water in pipes.Locating leaks in steam lines or steam traps.Detecting poor bearings on rotating machinery.Detecting defective gears.The operation of the Detector is the same as for corona detection; however, since there is no high-voltage hazard, the directional horn may be required to pinpoint the source of ultrasound if the source is not easily accessible. The rubber sound concentrator is useful to pinpoint small leaks. Slide it along the suspect surface to find the maximum signal point.Section GMAINTENANCEThe BIDDLE Cat. No. 569001 Detector requires no routine maintenance except to periodically replace the battery and examine the leads from the microphone probe and headphones. It is recommended that the receiver case, headphones and microphone occasionally be wiped clean with a dry cloth.Turn the receiver off when replacing the battery (located beneath the snap-flap on the leather case).TROUBLESHOOTING and REPAIRIn the event the Detector does not work, first try replacing the battery. If this does not solve the problem, localize the trouble by disconnecting the microphone probe and headphones and turn the receiver on. Set the volume control up to almost full; if the receiver is operating a characteristic background noise will be heard on the speaker and the meter will read. To check the headphones use an ohmmeter at the plug, checking between the metal closest to the shell and (a) the insulated ring, and (b), the tip. Each should measure about 10 ohms.To check the microphone probe, connect it to a test set that is known to be operating. Do not make an ohmmeter measurement of the microphone as this may damage it.Before returning a set for repair make certain that the battery is not at fault. Headphones and microphone probe can be replaced without returning the test set.PARTS LISTThe following parts are available from AVO International for use on the Corona and Leak Detector:NUMBERITEM PARTReceiver 569001-1Carrying Case 569001-5-3Headphones 569001Microphone Probe 569001-2Directional Horn 569001-6Sound Concentrator 569001-4Instruction Manual 56-9JThe Accessory Items 569001-7 and 569001-8 must be replaced as a unit if defective.Section HWARRANTY AND REPAIRSWARRANTYAll products supplied by AVO BIDDLE Instruments are warranted against all defects in material and workmanship for a period of one year following shipment.
