10kV MV Indoor Vacuum Circuit Breaker/VCB for Switchgear,VAC83-12KV

1. General description

VAC83 VCB is in a new type indoor switch device,which is mainly used in three-phase AC power system with rated voltage of 12kV,and rated frequency of 50-60Hz.It has the advantages of compact structure,high reliability,small operation vibration and easy maintenance.It can be widely used in power plant,steel plant,metallurgy,petrochemical,transportation,building and other industrial and mining enterprises as a switch device for protection of high voltage motors,transformers,line faults and other loads.

2. Product characteristics

Taking different functional units as the dividing line to realize the full 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.

4. Full modular structure

The full modular structure design makes the overall function structure of VAC83 circuit breaker clear,operation and maintenance simple and reliable.

Modular parts can be replaced quickly without affecting product characteristics.

Motor

-Opening and closing tripping coil

-Overcurrent tripping coil

-Locking tripping coil

Secondary control parts that is easy to maintain

-Control switch of energy storage position

-Control switch of opening and closing position

-Secondary control module

Equipped with operation handle which is easy to operate and more humanized.

Our design more consider the use and maintenance convenience and fast for user.For wearing parts such as opening and closing electromagnet,motor,overcurrent tripping electromagnet and other components,can achieve very convenient and fast replacement,which is more humanized.
