GCHL-100B开关回路电阻测试仪(固定档位)产品简介

目前(qian)，接(jie)(jie)触(chu)电(dian)(dian)(dian)(dian)(dian)阻(zu)的(de)测(ce)量(liang)(liang)电(dian)(dian)(dian)(dian)(dian)力(li)系统中(zhong)普遍采用常规(gui)(gui)的(de)QJ44型双臂直(zhi)流(liu)电(dian)(dian)(dian)(dian)(dian)桥(qiao)，而这类电(dian)(dian)(dian)(dian)(dian)桥(qiao)的(de)测(ce)试电(dian)(dian)(dian)(dian)(dian)流(liu)仅(jin)m*，难以发现回路导体截面积减少的(de)缺陷，在测(ce)量(liang)(liang)高(gao)压开(kai)关(guan)(guan)导电(dian)(dian)(dian)(dian)(dian)回路接(jie)(jie)触(chu)电(dian)(dian)(dian)(dian)(dian)阻(zu)时，由于(yu)受触(chu)头(tou)之间油膜和(he)氧化层的(de)影响(xiang)，测(ce)量(liang)(liang)值偏(pian)大若干倍，无法真实的(de)反映接(jie)(jie)触(chu)电(dian)(dian)(dian)(dian)(dian)阻(zu)值。为(wei)此，电(dian)(dian)(dian)(dian)(dian)力(li)部(bu)标准SD301—88《交流(liu)500KV电(dian)(dian)(dian)(dian)(dian)力(li)设(she)备交接(jie)(jie)和(he)预防性试验(yan)规(gui)(gui)程》和(he)新版《电(dian)(dian)(dian)(dian)(dian)力(li)设(she)备预防性试验(yan)规(gui)(gui)程》作出对断(duan)路器、隔离开(kai)关(guan)(guan)接(jie)(jie)触(chu)电(dian)(dian)(dian)(dian)(dian)阻(zu)的(de)测(ce)量(liang)(liang)电(dian)(dian)(dian)(dian)(dian)流(liu)不小于(yu)直(zhi)流(liu)100A的(de)规(gui)(gui)定，以确保试验(yan)结果准确。

该回(hui)(hui)(hui)路(lu)电(dian)(dian)(dian)阻测(ce)(ce)试(shi)仪是根据中华(hua)人民共和(he)国(guo)电(dian)(dian)(dian)力(li)执行标准(zhun)DL/T845.4-2004，采用高频开(kai)关电(dian)(dian)(dian)源技术(shu)和(he)数字电(dian)(dian)(dian)路(lu)技术(shu)相(xiang)结(jie)合设计而(er)成。适(shi)用于(yu)开(kai)关控(kong)制设备回(hui)(hui)(hui)路(lu)电(dian)(dian)(dian)阻的(de)测(ce)(ce)量(liang)。其测(ce)(ce)试(shi)电(dian)(dian)(dian)流(liu)采用国(guo)家标准(zhun)推荐的(de)直(zhi)流(liu)100A和(he)200A。可(ke)(ke)在(zai)电(dian)(dian)(dian)流(liu)100A的(de)情况(kuang)(kuang)下(xia)直(zhi)接(jie)测(ce)(ce)得(de)回(hui)(hui)(hui)路(lu)电(dian)(dian)(dian)阻，也(ye)可(ke)(ke)以在(zai)电(dian)(dian)(dian)流(liu)200A的(de)情况(kuang)(kuang)下(xia)直(zhi)接(jie)测(ce)(ce)得(de)回(hui)(hui)(hui)路(lu)电(dian)(dian)(dian)阻，zui后(hou)的(de)测(ce)(ce)试(shi)结(jie)果都用数字显(xian)示出来(lai)。该回(hui)(hui)(hui)路(lu)电(dian)(dian)(dian)阻测(ce)(ce)试(shi)仪测(ce)(ce)量(liang)准(zhun)确(que)、性能(neng)稳(wen)定，符合电(dian)(dian)(dian)力(li)、供电(dian)(dian)(dian)部门现场(chang)高压(ya)开(kai)关维修和(he)高压(ya)开(kai)关厂回(hui)(hui)(hui)路(lu)电(dian)(dian)(dian)阻测(ce)(ce)试(shi)的(de)要求(qiu)。

GCHL-100B(固定档位)产品参数

技术参数

GCHL-100B(固定档位)产品特征

• 1、大电(dian)流(liu)：回路电(dian)阻测试(shi)仪采用(yong)电(dian)源(yuan)技(ji)术，能长时间连续输出大电(dian)流(liu)，克服了脉冲式电(dian)源(yuan)瞬间电(dian)流(liu)的弊端，可以(yi)有效的击穿开关触头氧化(hua)膜，得到良好的测试(shi)结果

• 2、抗干扰能(neng)力(li)强：在严重干扰条件下，液晶屏zui后一(yi)位数(shu)据能(neng)稳(wen)(wen)定在±1个字范(fan)围内，读(du)数(shu)稳(wen)(wen)定，重复(fu)性好

• 3、本回路电阻(zu)测试仪使用寿(shou)命(ming)长：全部采用高精度电阻(zu)，有效的消除(chu)环境温度对测量结(jie)果的影(ying)响，同时菲柯(ke)特品牌接(jie)插件的使用增强了抗振(zhen)性(xing)能

• 4、携带方便：体积(ji)小、重量(liang)轻(qing)
