General:
P-1A spring operating mechanism is specially developed for middle-placed vacuum circuit breakers, which is widely used in domestic market. The operating mechanism frame dimension is the same with that of VS1, VD4, so it can be freely used in VS1 and VD4. The P-1A operating mechanism meets requirements for operating mechanism technical conditions of GB1984-2003 AC High-voltage Vacuum Circuit Breaker and IEC56.
Technical features:
1. The perfect interlocks is easy for using and match-production;
2. The modular operating mechanism is easy to maintain;
3. Both the assembled insulation cylinders and embedded poles can be assembled together with the P-1A spring operating mechanism;
4. The connecting dimension of P-1A is same with that of VS1 and VD4 circuit breaker;
5. The mechanism endurance is long, and can reach to 60000 times.
