高压无线核相仪的详细介绍
一、数显高压无线核相仪产品简介
★数显高压无线核相仪简介
数显高压核相仪，应用于电力线路、变电所的相位校验和相序校验，具有可靠的高电压电气安全隔离性能，符合电力行业标准，标准编号DL/T971-2005;具备很强的抗干扰性，符合电磁兼容性(
EMC )标准。本产品安全可靠、性能稳定、操作简便，是一种理想的核相仪器。
数显高压核相仪性能指标
●准确度：同相误差≤10°，不同相≤15°
●主机电源9V±2V
●采集器电源7.5V±1.5V
●采集器X、Y与主机的视距传输距离≤70米
●采集器采集的电压等级为0.22KV-500KV
●工作温度-35℃- +50℃
●可伸缩绝缘操作杆:缩态为600mm,伸态为3000mm
●包装箱尺寸：长×宽×高)650mm×250mm×100mm
●产品重量：主机重约0.3Kg，重约5Kg。
★数显高压无线核相仪系统组成及特点
测试系统组成：主机(接收)、X采集器(发射)、Y采集器(发射)、针式和挂钩式两种采集头、可伸缩绝缘操作杆等所组成。(附件包括铝合金包装箱、备用电池、带插头的专用校验测试线夹)。
本系统全部采用数字电路，功能齐全、功耗低，正常使用每年更换一次电池即可(因普通电池自然放电)。当X和Y采集器或主机电源电压低时，主机屏幕有低压告警显示。
★数显高压核相仪安全可靠
X和Y采集器，将采集到的电压相位信号通过无线信号发往主机，具有可靠的高电压电气安全隔离性能。本产品全部采用数字电路，抗干扰性强、数据稳定准确。
★方便快捷
X和Y采集器使用方便，主机具有自动关机功能。绝缘杆采用可伸缩式拉杆，现场核相时不需要任何连线，核相距离可达70米，并不受现场各种条件影响，全部核相过程只需两人在2分钟内就可完成。
★更多功能
可在两个不同的电压等级间进行核相，既可定性测量(同相、不同相)，又可定量测量(两供电线路相角差如30°、60°等)。
测量相序：正相序120°，逆相序240°。
验电功能：当X或Y采集器的采集头接触到高压线路或电气设备的带电部分时，如线路或设备有电，主机则显示X或Y。
二、数显高压无线核相仪概 述
高压核相仪，将被测高电压相位信号由采集器取出，经过处理后直接发射出去。由核相仪接收并进行相位比较，对核相后的结果定性。因本产品是无线传输，真正达到安全可靠、快速准确，适应各种核相场合。
三、数显高压无线核相仪安全事项
1、现场核相时，操作人员必须按照《电力安全工作规程》的标准要求进行操作。
2、可伸缩绝缘操作杆的电压等级为 ≤ 220KV 。
3、在≥66KV线路或电气设备上核相时，X和Y采集器应采取非接触方法核相。
