General Introduction:

1.Product model:CT36-252/145/126/72.5

2.Product name: Spring operating mechanism

3.Product scope and main reference standards:

  This mechanism is suitable for 72.5kv -220kV high voltage AC SF6 breaker, and its performance is meet:

   IEC 62271-2008 《 Alternating-current circuit-breakers》

   IEC 62271-2007 《High-voltage switchgear and controlgear》

   IEC60056-1987 《High-voltage alternating-current circuit-breakers》

4.The mechanism has two charge modes: electric and manual. An anti-misclosing device with mechanical interlocks; The opening and closing operation has remote control, local operation, electric operation and manual operation

5.The double - divider coil adopts the independent parallel structure, which makes the opening operation more reliable

6.With the aid of special tools, the mechanism can be opening and closing slowly.
