    Zhuhai Strom Smart Grid Tech Applies for Patent on Miniature Circuit Breaker Simulation Device and Use Method


    May 5, 2022 - Electrical Patent News

     

      Beijing, May 5 -- Zhuhai Strom Smart Grid Tech has applied for Chinese patent for miniature circuit breaker simulation device and use method. Li Jianming, Xie Wenjie, Cheng Huazhi and Li Mengqing developed it.

      The patent application number is CN202110240421 20210304. The patent publication number is CN112858826 (A). International Patent Classification codes are G01R1/20 and G01R31/00. Cooperative Patent Classification codes are G01R1/20 (CN), G01R1/206 (CN) and G01R31/00 (CN).

      The abstract of the patent published by the State Intellectual Property Office of China states: "The invention provides a miniature circuit breaker simulation device and a use method. The miniature circuit breaker simulation device comprises a connector, a connector joint is provided with a simulation circuit module capable of generating a test simulation signal, and the simulation circuit module comprises a closing relay, an opening relay, a closing signal relay, a closing signal indicating lamp and an opening signal indicating lamp. A closing input pin H1 of the connector is connected with a normally closed contact of the closing relay, a normally open contact of the closing relay is connected with a coil end of the closing signal relay, an opening input pin F1 of the connector is connected with a coil end of the opening relay, and a normally closed contact of the opening relay is connected with the coil end of the closing signal relay. The normally closed contact of the closing relay is connected with the opening signal indicating lamp, and the normally closed contact of the closing relay is connected with the closing signal indicating lamp. The invention provides a circuit breaker simulation device which is smaller in size and lower in cost, and the circuit breaker simulation device is small, light and popular while the function of a simulation circuit breaker is met."
