Product Description

变压器特性测试台介绍


主要作用:


用于测试开关触点、断路器接点、母线、接点、SF6开关、各种连接、熔断器及铁路的连接的直流电阻。工作原理:M400利用一个可控硅整流电路进行调整测试电流预定值,此电流经过整流、滤波后被施加在被测样品,直接测出阻值。在这个电流中,电压施加在未知的被测电路和已知阻值的电路后进行比较,读数显示在数字安培计上。测式原理采用四端测试方式,四端连接的方式被用于被测的未知电阻及其并联的电路上,测试电路及其选择开关决定测试范围。

Safety Measures:


1. Read this manual carefully before using the instrument.


2. Operators should possess general electrical knowledge.


3. Avoid using the instrument in rain, corrosive gas, excessive dust, high temperature, direct sunlight, and similar environments.


4. Avoid severe vibration.


5. After testing, wait until the discharge alarm stops before powering off and removing test leads.


6. When measuring no-load tap-changing transformers, wait until the discharge indicator alarm stops before switching taps.


7. Do not move test clips or power supply wiring during testing.


Precautions


1、对无载调压绕组,不允许在测试过程中或未放完电时切换无载分接开关。


2、对感抗性测试对象,在没有放完电(蜂鸣器鸣响时)情况下,不允许拆除测试线,以免遭电击。


3、测试过程中遇到外部AC220V突然断电,仪器将开始自动放电,此时不允许立即拆除测试线,5分钟后方可拆线。
