Product introduction

Vacuum arc extinguishing chamber, also known as vacuum switch tube, is the core component of medium and high voltage power switch. Its main function is to quickly extinguish the arc and restrain the current after the medium and high voltage circuit cuts off the power supply through the excellent insulation of the vacuum inside the tube, so as to avoid accidents and accidents.

Product performance and parameters

Project

Performance description

Name

Vacuum arc extinguishing chamber

Structure

Air tight insulation shell, conductive circuit, shielding system, contact, bellows and other parts

Effect

It is mainly used in power transmission and distribution control system

Characteristic

Controlled contact burning makes the arc extinguishing chamber have longer electrical life and maintenance free operation.

High hardness contact materials greatly reduce contact fusion welding in vacuum, which is an ideal choice for high current applications.

The contact will not be oxidized and corroded, so the air contact pollution can be eliminated.

The vacuum arc is confined inside the vacuum interrupter, so there is no noise and external flash.

Environmentally friendly products, the current breaking is carried out inside the arc extinguishing chamber, so it will not release greenhouse or toxic gases into the atmosphere.

Low cutoff value generates low cutoff current voltage peak value, so surge suppressor is not required.

The vacuum medium makes the contact have smaller opening distance, so the circuit breaker can be miniaturized.

Solid insulation improves external dielectric properties
