▸ Product Introduction

Product overview

BGZ35-40.5 Special integrated circuit breaker for wind power box transformer, namely wind power circuit breaker and wind power integrated circuit breaker. It is an indoor high-voltage vacuum circuit breaker and integrated circuit breaker independently developed by Boshida Group Company with independent intellectual property rights.

The product is the control and protection device of three-phase AC 50Hz and 35kV distribution system, which is used to cut off load current, overload current, short circuit and current. The isolated indoor AC high-voltage vacuum circuit breaker with grounding has the function of protecting the transformer from overload and preventing the equipment from running out of phase. It is a good choice for wind turbine transmission network equipment.

BGZ35-40.5 combined electrical apparatus includes vacuum circuit breaker body, isolating switch, grounding switch, current transformer, voltage transformer and metal oxide arrester (including discharge counter), and the current transformer is installed between the circuit breaker and the transformer.
