The vacuum circuit breaker is named after its interrupting medium and the insulating medium of the contact gap after interrupting is high vacuum; it has the advantages of small size, light weight, suitable for frequent operation and interrupting without maintenance, and is more popularly used in the 3kV-40.5kV distribution network.
The components of vacuum circuit breaker are vacuum interrupter, electromagnetic or spring-operated mechanism, bracket and other parts.
Vacuum interrupter is the core component of vacuum circuit breaker, its main role is, through the excellent insulation of the vacuum inside the tube to make the medium and high voltage circuit cut off the power can quickly extinguish the arc and suppress the current to avoid accidents and accidents.
There are two kinds of operating mechanism: spring-operated mechanism and permanent magnetic operating mechanism.
The conductive circuit is divided into insulated cylinder form (vacuum interrupter is installed in the insulated cylinder) and sealed pole form (vacuum interrupter is installed in the epoxy resin).
The VSG mechanism uses a cam (in the core module of the mechanism) to drive the spindle directly (in the frame spindle module) to reduce the transmission link and improve the transmission efficiency (no hinge connection). Reduce the energy input of the product and increase the service life of the product. Install the main circuit module, that is, complete the basic configuration of the vacuum circuit breaker. Then install the chassis car module, the contact arm, the contact, and the insulating sleeve to complete the configuration of the hand-cranked circuit breaker.
