Product Description
1.General description
ZN83-12KV series of indoor M.V. VCB with lateral operating mechanism used spring to storage energy.The operating mechanism can be operated by two ways:by manual and electromotive operation.The characteristics is accordance with IEC standard 62271-1 00:2001 M.V. AC circuit breaker,JB3855-1996 3.6-4.5kv indoor AC M.V. circuit breaker and GB1984-2003 M.V. AC circuit breaker.
2.Product characteristic
Taking different functional units as the dividing line to realize the modular design. The integrated and optimized design minimizes the intermediate realization link of the functional unit, and the overall mechanism only has more than 70 parts.
There is no adjustment link in the mechanism to minimize the professional requirements for maintenance personnel.
The whole series of products are easy to operate.
Small mechanical operation vibration.
Mechanism with manual energy storage handle.
Fast replacement of wearing parts without special tools.
The whole series of mechanisms have passed the verification of 72 hour salt spray test.
3.Simple and reliable structure
Less closing interlocking parts, convenient integrated installation, effective prevention of false closing.
The opening adopts friction type structure, with small wear and failure rate, so as to improve mechanical life.
