Simple circuit breaker cabinet configuration standards
Beihai Yinhe Switchgear Co., Ltd. is a Sino-German joint venture, specializing in production of solid seal vacuum circuit breakers and related components, electrical equipment and other products, is Guangxi's largest solid seal vacuum circuit breakers and high-voltage equipment manufacturing enterprises. Its products have been widely used in power systems Chengwanggaizao, power plants, petrochemical, metallurgy, coal, substations, manufacturing and urban infrastructure such as airports, subways, docks and community and so on.
The main products are VYG Galaxy switch series solid seal vacuum circuit breaker (12kV ~ 40.5kV voltage level), VYGQ series closed GLX24 series RMU is a scalable SF6 gas insulated metal-enclosed Circuit breaker , voltage rating of 12kV, 24kV. Once all of the high-voltage live parts completely sealed by 3mm thick stainless steel plate welded SF6 gas tank, compact size. Throughout the switching device from the external environment, to ensure safe and reliable operation, and to achieve a maintenance-free. Through the plug-in expansion bus, to achieve any combination, to achieve full air circuit breaker . Expansion bus fully insulated and shielded, dynamic thermal stability through national type-tested to ensure high reliability and security. GLX24 series RMU Chengwanggaizao applied to power systems, power stations and load centers power plants, petrochemical industry, steel industry and mining, general enterprises, high-rise buildings.fully insulated solid seal vacuum circuit breaker (12kV ~ 40.5kV voltage level), eVYG series solid sealing phased breaker (12kV voltage level), SCG series solid seal vacuum circuit breakers, as well as GLX24 Series SF6 gas insulated ring main unit (12kV ~ 24kV voltage level). There are also KYN96, KYN28A, KYN61 other voltage rating of 12kV ~ 40.5kV the armored away metal-enclosed switchgear equipment, ZWB-12 digital substation.
GLX24 series RMU standard configuration: 630A busbar; 630A transformer protection with vacuum circuit breaker; vacuum circuit breaker spring operating mechanism; three-position load switch; three-position single spring operating mechanism, independent of the load switch and earthing switch operating shaft; vacuum breaker and three-position mechanical interlock and load switch position indication; EPS self-powered microcomputer relay protection devices; tripping coil (for relay operation); arranged horizontally in front of 630A with sensor function bushing; live display; For all switching functions, the panel has convenient installation padlock device; SF6 gas pressure gauge; grounding busbar; grounding switch under the front door and the front lower door interlock shaft associated with the operation lock; MCCB circuit breaker operating mechanism and industry development trend analysis of load switching operation between institutions interlock; secondary device (can be installed on top of the operating mechanism, without increasing the height of the cabinet).
Optional configuration with left and right outlet, and the left and right extension; ring current transformer for measurement and meter; cable entry bushing in place arresters can be installed or dual cable head; auxiliary contacts.
