VZF-12R indoor withdrawable handcart regular high medium voltage vacuum circuit breaker

Overview

VBG-12 series indoor high voltage vacuum circuit breaker adopts solid insulation structure, using standard epoxy solid sealing technology, for the first time, the vacuum interrupter, main circuit, insulation support and other organic combination into an integrated solid sealing pole. The problem of environmental tolerance of vacuum circuit breaker is solved successully, and its application is more extensive. The integrated solid seal pole adopts self-convection patented ventilation technology, which cleverly solves the problem of heat dissipation caused by solid insulation structure.

VBG-12 series indoor high voltage solid sealed vacuum circuit breaker is the first in China to achieve maintenance-free concept; Read the circuit breaker. Its high-life vacuum isolation chamber and the application of epoxy casting solid sealing technology ensure that the integrated solid sealing pole is maintenance-free, and can also be equipped with high-reliability permanent magnet operating mechanism to ensure that the operating mechanism is maintenance-free, the electronic control part of the traditional auxiliary switch instead of photoelectric proximity switch, and the use of fully electronic power supply and intelligent control unit to ensure that the electronic control part of the maintenance-free.
