Product Description

Timetric Lateral Indoor VCB Introduction

China Timetric Lateral Indoor VCB (hereinafter referred to as the circuit breaker) is suitable for the indoor switchgear of 12kV power system. As the protection and control unit of power grid equipment and industrial and mining enterprises, it is suitable for the occasions of throwing and cutting various loads of different nature and frequent operation and multiple times of short-circuit current. The product uses a new circuit breaker operating mechanism, the NGVSC primary part can use foreign brand solid sealing pole, the vacuum arc extinguishing chamber and the main circuit parts are sealed into a whole, protect the arc extinguishing chamber from collision, dust and condensation impact, strong adaptability to the environment, greatly reduce the operation and maintenance costs, truly realize a part of the product maintance-free, operating mechanism less maintenance; Operating mechanism and circuit breaker body - type design, through the type test verification; With E2 class electrical life, M12 class mechanical life.

Timetric Lateral Indoor VCB Feature And Application

The overall structure of the Lateral Indoor VCB adopts the form of operating mechanism and the front and back arrangement of the primary part. The primary part is three-phase floor structure. The upper and lower outlet seat and the arc extinguishing chamber are sealed together by epoxy resin APG process, so that there is no dust accumulation on the surface of the arc extinguishing chamber, which can prevent the vacuum arc extinguishing chamber from being damaged by external factors and ensure that it can be used in humid, hot and dirty environment.

Current path of main loop when circuit breaker is in closing position

From the upper outlet seat 21 to the static contact in the vacuum arc extinguishing chamber, through the moving contact, the moving conductor rod and the soft connection connected with it, to the lower outlet seat 20.

Timetric Lateral Indoor VCB Details

The Lateral Indoor VCB operating mechanism is a modular spring energy storage operating mechanism. The operating mechanism is integrated with a closing unit, an opening unit composed of one or several overcurrent tripping electromagnets, an auxiliary switch, an indicating device and other components; The front is equipped with closing and parting buttons, manual energy storage handle, spring energy storage status indicator, closing and parting indicator, etc.
