Key Features

1. Reliable modular spring operating mechanism: the spring operating mechanism is a spring operating mechanism arranged up and down, with manual energy storage and electric energy storage functions, the overall size of the whole machine is small, the overall rigidity of the circuit breaker is good, and the operating performance Consistently.

2. The electric circuit adopts a sleeve type structure: the vacuum interrupter of the primary electric circuit of the circuit breaker is arranged in a closed insulating cylinder. The insulating cylinder is made of epoxy resin material with reliable electromechanical properties and advanced APG technology. Forming, the insulating cylinder can not only install and support, but also play the role of phase-to-phase and relative-to-ground insulation.

3. Standard closing and opening function modules: Modular design spring mechanism is another feature of VS1 indoor vacuum circuit breaker. The spring operating mechanism includes two function modules of closing and opening, which are easy to maintain and replace. Fast, short maintenance time for power failure. In addition, since the closing and opening function modules used as spare parts have been lubricated and adjusted by special grease and have a long shelf life, there is no need to repair the entire circuit after the closing and opening modules are replaced. The operating mechanism of the circuit breaker can be readjusted without changing the dynamic characteristics of the circuit breaker, so that the maintenance and repair work is reduced to a minimum.

4. Good handcart interchangeability and adaptability, and the installation size can be used with ZN85, VD4 and other series products.

5. Strong breaking capacity and long service life.
