Vacuum Circuit Breaker
As a professional power transmission and distribution manufacturer in China, KEX® has been producing vacuum circuit breakers for more than ten years, and has many patents and certifications.
High-voltage vacuum circuit breaker is a kind of switchgear using Vacuum Interrupter as arc extinguishing medium, which is widely used in 6kV~40.5kV medium and high voltage power systems,Its structure is mainly divided into arc extinguishing chamber and operating mechanism, which includes spring mechanism, permanent magnet mechanism and electric spring.
High-voltage vacuum circuit breaker is mainly suitable for the following scenarios:
▶ Substation: medium voltage distribution protection
▶ Industrial Plants: motor/transformer protection
▶ Renewable Energy: wind power/photovoltaic grid connection.
▶ Rail transit (Railway)
Characteristics of high-voltage vacuum circuit breaker：
High-voltage vacuum circuit breaker (VCB) is the core switchgear of medium-high voltage power system, which has the advantages of long service life, maintenance-free and environmental protection (SF6-free), and is suitable for substation, industry, new energy and other fields. If you need the terms of special environment (cold/salt fog) or intelligent upgrade (digital twin), you can further refine the requirements like Kex®!
