把电线的绝缘皮去除6到8mm,再将露出的电线插入接线端子里,使用螺丝刀拧紧顶端的螺丝,并用手拉几下,看是否会出现电线脱落的情况,确定电线与接线端子连接牢固后,再将开关按下,待灯亮起后,说明接线端子接线已成功。

1、笼式弹簧接线用工具把弹簧打开,然后接入导线或取出导线。

2、弹片式接线把导线插进接线孔即可,用螺丝刀把按键下压的话就可以取出导线。

3、螺钉式接线把导线放进去,然后用额定扭力值锁紧螺钉就可以了,松退螺钉完成取线。

4、冷压式接线把导线放到金属件里,然后用工具压紧就可以了。

In this manual the word “WARNING” is used to indicate conditions or actions that may pose physical hazards to the user. The word “CAUTION” is used to indicate conditions or actions that may damage this instrument.WARNINGTo ensure safe operation and service of the tester, follow these instructions. Failure to observe these warnings can result in severe injury or death.WARNING• Before each use, verify meter operation by measuring a known voltage or current.• Never use the meter on a circuit with voltages that exceed the category based rating of this meter.• Do not use this meter during electrical storms or in wet weather.• Do not use the meter or test leads if they appear damaged.• Ensure meter leads are fully seated and keep fingers away from the metal probe contact when making measurements. Always grip the leads behind the finger guards molded into the probe. For information on test lead shields instructions on page 19.• Do not open the meter to replace batteries while the probes are connected. • Use caution when working with voltages above 60 DC or 25 AC RMS. Such voltages pose shock hazards.• To avoid false readings that can lead to electrical shock, replace batteries if a low battery indicator appears.• Unless measuring voltage or current, shut off and lockout power before measuring resistance or capacitance.• Always adhere to national and local safety codes. Use proper personal protective equipment (PPE) to prevent shock and arc blast injury where hazardous live conductors are exposed.• Always turn off power to a circuit or assembly under test before cutting, unsoldering or breaking the current path. Even small amounts of current can be dangerous.• Always disconnect the live test lead before disconnecting the common test lead from the circuit.• In the event of electrical shock, ALWAYS bring the victim to the emergency room for evaluation, regardless of victim’s apparent recovery. Electrical shock can cause unstable heart rhythms that may need medical attention.• If any of the following occur during testing, turn off the power source to the circuit being tested: arcing, flame, smoke, extreme heat, smell of burning materials or discoloration or melting of components.WARNINGHigher voltages and currents require greater awareness of physical safety hazards. Before connecting the test leads; turn off power to the circuit under test, set meter to the desired function and range; connect the test leads tothe meter first, then connect to the circuit under test. Reapply power. If an erroneous reading is observed, disconnect power immediately and recheck all settings and connections.WARNINGThis meter is designed to provide HVAC/R technicians with the capabilities they need to diagnose and repair HVAC/R system. Observe all recommended safety procedures that include proper lockout utilization and use of personal protective equipment that includes safety glasses, gloves and flame resistant clothing.AC (Alternating current)DC (Direct current)Negative AC/DC Voltage or CurrentAuto-ranging Overload: Range ExceededkHz Low pass Filter BT Wireless Connection Auto power off Active Non-Contact VoltageLow Battery Hold/Capture ValueMinimum measured value displayed Maximum measured value displayedDuty Cycle Hertz/FrequencyVoltage InrushAmperage Ohms/ResistanceDiode CapacitanceNanofaradµF MicrofaradMicroamps ContinuityDegrees Fahrenheit Degrees CelsiusMega (x106 or 1,000,000)Milli (x10-3 or 0.001)Kilo (x103 or 1,000)Micro (x10-6 or 0.000001)Warning or Caution GroundDangerous Levels Double Insulation(Protection to Class II) Safe for disconnect fromlive conductors No reading detected AVG Average EF Electric FieldT1Temperature input 1T2Temperature input 2 M Mega Ohms k Kilo OhmsMeasurement Category Short-Circuit(typical) kA aLocation in thebuilding installationII< 10Circuits connected to mains socketoutlets and similar points in the MAINSinstallationIII< 50Mains distributions parts of the building IV> 50Source of the mains installation in thebuildingA.

海上平台滤波器的使用

海上平台滤波器的使用

工艺与设备化 工 设 计 通 讯Technology and EquipmentChemical Engineering Design Communications·114·第45卷第2期2019年2月1 引言目前海上油气田平台所使用的滤波器主要包括无源滤波和有源滤波两种,下述将分别进行简介。

2 无源滤波器无源滤波器是利用电阻、电抗器和电容器元器件构成的滤波电路。

谐振频率时,电路阻抗值最小,非谐振频率时,电路阻抗比很大,将电路元器件数值调整到某一特征谐波频率,则能滤除该次谐波电流;当若干谐波频率的调谐电路组成在一起,则能滤除对应的特征谐波频率,通过低阻抗旁路实现对主要次数谐波(3、5、7)的过滤。

主要原理就是针对不同次数谐波,设计该谐波频率的阻抗为很小,实现谐波电流的分流效应,即为预滤除的高次谐波提供旁路通道,实现净化波形。

无源滤波器按接线形式可分为电容滤波器、电厂滤波电路、L 型RC 滤波电路、π形RC 滤波电路、多节π形RC 滤波电路、π形LC 滤波电路。

按功能可分为单调谐滤波器、双调谐滤波器、高通滤波器。

无源滤波器具有如下优势:结构形式简单、投资费用低,能够补偿系统中的无功分量、改善电网功率因数;工作稳定性较高、维护简单、技术成熟等,在有源滤波器出现以前被广泛采用。

无源滤波器的缺点也有很多方面:受电网参数的影响较大,系统阻抗值和主要次数谐振频率往往随着工况发生变化;谐波滤除的频带也较窄,只能滤除主要次数的谐波,或因发生并联谐振,放大一些次数的谐波;滤波和无功补偿及调压之间的协调较困难;随着流经滤波器的电流升高,可能造成设备过负荷运行;耗材多,重量和体积都较大;运行稳定性较差等缺点。

因此,整体性能更优的有源滤波器得到越来越多的应用。

3 有源滤波器有源滤波器主要作用不仅能动态追踪并抑制谐波,而且可以补偿电网中较低的无功分量。

它能够对幅值和频率都波动的高次谐波分量进行补偿,以及对变化的系统无功分量进行动态补偿,克服了传统型式谐波治理方案和无功补偿的缺点,达到了动态跟踪补偿的效果。

DL850使用方法及注意事项

DL850使用方法及注意事项

DL850使用方法1、DL850概述DL850全称为DL850型示波记录仪。

现采购的DL850配备6个2通道电压模块720210(通道数6*2),1个16通道扫描型电压模块720220。

6个电压探头,3个交直流电流钳,1个电流探头。

波形存储容量为160G,1GPts内存。

单个波形存储最大点数为1G。

2、基本概念2.1录波仪及示波器的精度问题。

其数据的可靠性由12位AD决定,比如实测值为5V,用5格(纵轴共有10格)显示波形,则使用的AD点数为5*212/10=2048测试用的数据位的精度为1/2048=0.05%,对5V 输入误差值约为2.4mV。

示波器是8位的AD,因此数据显示为5格情况下的精度约为0.78%左右。

2.2采样率、记录长度的选择单屏录波时间由刻度决定,若刻度为200ms/div,录波时间计算为200ms*10=2s。

总录波时间横河此款产品的数据记录长度最大为单通道1G点数,则录波最长时间由采样率决定,若采样率为100MS/s,则横轴刻度自动选择为1s/div,可计算最长时间为1GS/(100MS/s)=10s;若采样率为50kS/s,则最长录波时间为1GS/(50kS/s)=333min。

老录波仪DF1024的采样率最大为50000S/s,每周波点数为1000S,经常使用的采样率为25000S/s,每周波点数为500S。

由于使用习惯的问题,横河录波仪存在一定的操作复杂性,现给出几种常用的设置方式供参考使用。

采样点数过多和采样率均多时,会出现波形分析工具打开波形出错,现象是波形刻度出错。

缺点:存储波形较大时,存储速度较慢,时间5min,采样率50 kS/s,数据长度1M波形,csv文件大小约214M,存储时间约需要10min。

3、如何进行电压录波电压通道精度和测量模块有关系,电压录波通道的精度为0.5%。

使用方法:1)选择合适的电压探头,此款标配电压探头为700929,带宽DC~100MHz,电压范围0~1000V。

三相分离器操作改终(内容)

三相分离器操作改终(内容)

目录一﹑设计参数二﹑工作原理三、操作说明附件1:投运操作步骤附件2:操作规程油气水三相分离器操作说明为确保三相分离器顺利投产和投产后的顺利运行,编制了三相分离器投运方案。

一﹑设计参数稳定处理液量:≤70m3/h(1680m3/d)处理气量:≤30000Nm3/d脱水温度:45℃运行压力:0.1-0.25MPa(可根据现场情况定)处理后原油含水:≤0.5%处理后污水含油:≤300mg/l二﹑工作原理结构简图:工作原理:油气水混合来液进三相分离器后,初步进行液气分离。

伴生气通过一级分离、二级捕雾器处理后,进入站内气处理系统。

油水混合物进入内部各处理单元,在沉降室开始分离,形成油水层。

通过调节水室导水管的高度,形成稳定的油水界面。

沉降室内上部的油溢流进油室,通过浮子液面调节阀调节出油阀开度,自动控制油室液面高度。

沉降室内底部的水通过导水管流入水室,通过浮子液面调节阀调节出水阀开度,自动控制水室液面高度。

油、水室液位可以通过浮子液位计显示,也可以在中控室通过导波雷达来观测。

油、水室液位的排放有两种方案,一种是机械式浮子液位调节阀控制;另一种是设定油水室液位,由导波雷达液位计控制电动调节阀的开度来控制。

油水室液位采用导波雷达和电动阀自动控制时,油水室的上限高度设定为1.7m,下限高度0.7m。

(导波雷达显示的液位与磁翻柱液位计显示的不一样,导波雷达从底部计算,磁翻柱液位计从离底部1米处计算。

)三、操作说明(一)投运操作说明1、新设备的第一次操作按照投运方案执行(见附件)。

2、设备投运后停运,再次启运,分两类情况。

第一类情况:设备停运时间长,容器排空。

首先向容器内充入1/2容器容积的热水,操作上可按照新设备的操作步骤进行。

在充液过程中,容器内压力升高,需要通过容器放空阀排放。

通过摸人孔的温度,判断容器内液体的高度。

充水工作完成后,可直接进液。

第二类情况:设备停运时间短,容器没有排空。

投运时可直接向容器内进液。
