Product introduction

At present, the DC circuit breaker ampere second feature detection agencies and manufacturers for DC empty open ampere second characteristic measurement equipment are fixed equipment such as stationary high-current power , a large load resistance , bulky , heavy and not easy motion detection , analytical instruments are conventional instruments such as voltmeter, ammeter , oscilloscope , wiring complexity , inconvenient to use and does not meet the substation movement detection needs. In order to solve the actual scene of the DC circuit breaker feature detection problems, Nanao Electric Wuhan Co., Ltd. has introduced a suitable substation site to use, easy to carry, high degree of automation "NAAS DC circuit breaker ampere second characteristic tester " can DC for the operation and maintenance departments to provide protection of electrical operating characteristics of the means test, the DC protection of electrical characteristics and the differential with the action be verified in order to improve the current system's reliability , to ensure safe and reliable operation of the grid . NAAS DC circuit breaker ampere second characteristic tester is designed for substation testing , repair , maintenance and design. Meet the DC circuit breaker overload and short-circuit characteristic test , thereby improving the health of substation DC system , avoiding the DC distribution network appears grade trip and caused large-scale power outages .

Also called name

DC circuit breaker ampere second characteristic tester, Ann second feature, the DC circuit breaker ampere second characteristic tester
