Factory 110kv disconnector The Neutral Point Of Transformer Equipment surge arrestor and Switch Disconnector

Overview

XD-BZJ-110/220  series transformer neutral point of complete sets of equipment  is  according  to  DL/ T620-1997' overvoltage protection and insulation coordination of'Regulations on 110kV/220kV   transformer   neutral  point of  power network using gap protection of AC electrical apparatus manufacture, and in accordance with the  China  State  Grid Corp in 2005 June published"important eighteen anti-accident  measures"  to  prevent  Check  the  grounding overvoltage accidents and technical requirements for the desing.Suitable for 110kv and 220kv effective grounding power network not grounding transformer neutral point overvoltage protection .

In order to make the transformer neutral point 100kv 220kv substation equipment performance,reliable,easy to install,the debugging and operation layout is simple and  beautiful, XIYA  electric  also introduced  the  transformer neutral point set of transformer neutral point rod gap, gap  current  transformer , isolating  switch,   lightning   arrester, terminal box and a mounting bracket and other electrical equipment in one of the sets equipment.

Transforme  neutral  users  can  independently choose pure clearance point  overvoltage  protection scheme, also can choose the gap and arrester parallel work,collaborative protection scheme.Lightning arrester and isolating switch according to the need of engineering,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,also Can be convenient in use field correction.
