一种三相不一致时间继电器校验装置的设计

文章研究一种时间继电器校验仪用来校验不同厂家、不同类型的断路器本体三相不一致时间继电器,解决因断路器的三相不一致时间继电器质量良莠不齐导致的设备投运后的安全隐患。该三相不一致时间继电器校验装置应具备校验准确、操作简单、使用方便、便于携带等优点。

In this paper, a time relay calibrator is developed to verify the three-phase inconsistent time relay of different manu-facturers and different types of circuit breakers, in order to solve the equipment safety hidden trouble caused by the uneven quality of the three -phase inconsistent time relay of the circuit breaker. The calibration device of the three -phase inconsistent time relay should have the advantages of accurate verification, simple operation, convenient use and portability.
