Sulfur hexafluoride breaker SF6 disconnector for GIS / RMU

Product Introduction

Sulfur hexafluoride circuit breaker is oil-free switchgear that uses SF6 gas as the insulating medium and arc extinguishing medium. Its insulation performance and arc extinguishing characteristics are much higher than that of oil circuit breakers. Because of its higher price and low resistance to SF6 gas Application, management, and operation have high requirements, so the application in medium voltage (35, 10kV) is not wide enough, and it is mainly used for voltage levels above 110kV.

Structure
Tank type: The advantages of the box-type multi-oil circuit breaker are used. The circuit breaker and the transformer are installed together. The structure is compact, and the earthquake resistance and pollution resistance are strong, but the series is poor. The single-phase structure of the China LW-220 tank-type SF6 circuit breaker is shown in the figure "Sulfur hexafluoride circuit breaker". This type of circuit breaker is a three-phase sub-assembly type. The single-phase is composed of a base, an insulating porcelain bushing, a current transformer and a shell equipped with a single-fracture arc extinguishing chamber. Each phase is equipped with a hydraulic mechanism and a control cabinet, which can be operated individually and can be operated in three phases through electrical control. The circuit breaker adopts a two-way longitudinal blowing arc extinguishing chamber. When opening, the cylinder and the movable contact are driven to move through the arm box transmission mechanism. The arc extinguishing chamber is filled with SF6 gas with rated pressure of 6 gauge (20°C).
