Detail Information
Transformer Neutral Point BZJ 110V 220V  Series  of Complete Sets of Equipment From Jucro Electric

   BZJ-110/220 series transformer neutral point of complete sets of equipment according to DL/T620-1997 Regulations on the 110kV/220kV transformer neutral point of power network uses the gap protection of AC electrical apparatus manufacturing , and in accordance with the China State Grid Corp in 2005 June published in the process if design . Application of 110kV and 220kV effective grounding power network without transformer neutral point grounding overvoltage protection.

    In order to make 110kV transformer neutral point of 220kV substation equipment performance is reliable, convenient installation, commissioning and operation layout is simple and beautiful, the company also introduced the transformer neutral point transformer neutral point rod gap, gap current transformer, isolating switch, lighting arrester, terminal box and a mounting bracket and other electrical equipment in one of the complete sets of equipment.

   The user can choose the transformer neutral point of pure clearance overvoltage protection scheme, also can choose the gap and Arrestor in parallel, collaborative protection scheme. Lighting arrester and the isolation switch according to the need of the project, with flexible group. The actuator isolation switch can be operated manually or electrically. Electrical and mechanical properties of all the products are finished debugging and full set of test before leaving the factory, but also convenient in use and correction.
