Voltage switchgear and transformer switchgear cabinet selection problem is an electrical device, outside the first master switch into the cabinet, and then enter the sub-control switch, Kaifeng low voltage switch, each branch according to need. Such as instrumentation, automation, motor magnetic switch, all kinds of exchanges and contacts, and some also set up the high-pressure chamber and the low-voltage switchgear room with high-voltage bus, such as power plants, and some also have major facilities in order to protect low-cycle .1 load shedding, high voltage switchgear vacuum circuit breaker inside the car after closing the test position, the car can not enter the work breaker position. (To prevent closing with load) 2, High Voltage Switchgear knife inside the ground at the time of closing position, Gongyi low voltage switch, the car can not enter the circuit breaker closing. (With a ground wire to prevent closing) 3, high voltage switchgear vacuum circuit breaker in the closing work within and panel back door and door lock with a mechanical knife on the ground. (To prevent mistakenly charged interval) .4, vacuum circuit breakers high voltage switchgear at work within the closing, ground knife can not be put together. (Antistatic articulated ground) 5, the vacuum circuit breaker at work within high voltage switchgear closing operation, you can not quit working position car breaker. (To prevent negative Hera Knife) KYN10-40.5 high voltage cabinet details sturdy cabinet, effective pressure relief channel can withstand shock and burning internal arc fault, low voltage, the effective protection of operator safety. Breaker compartment Doors and reliable interlock circuit breaker, only the circuit breaker compartment door closed, to operate circuit breakers, close, open and convenient to operate, rugged and reliable door. Combined shutter open and flexible, with the circuit breaker is pulled out, the shutter automatically closes and mandatory locking Ground interlock, secondary plug locking simple and reliable to meet the "Five Anti" functional requirements. Design unique propulsion mechanism causes Used in advancing the launch process can automatically find the place, once isolated from the contact contacting more reliable. Can be equipped with Floor-ZN85, VD4 (ABB), ZN72 (Jiangsu Dongyuan), ZN107 (Jilin Yongda), Qingfeng low voltage, VHM1 (Jilin Heng Tong), VEP (Xiamen Huadian), FP (Areva), VY4 ( Yangzhou universal), and other circuit breakers; can be equipped with mid-mounted VB-40.5 (GE), ZN48 (Pacific), SF1 (Schneider) and other circuit-breaker protection class: shell IP4X, compartment between the low pressure switch is IP2X Gongyi City. , Xi Connaught Electrical and Mechanical (online consultation), low voltage provided by the Henan learning Connaught Electrical and Mechanical Equipment Co., Henan Xi Connaught Electrical Equipment Co. (www.hnxinuo.com) is Zhengzhou, electronics, electrical products processing leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In practice Connaught Electrical and Mechanical leadership with the staff warmly welcome all inquiries negotiations to create learning Connaught Electrical and Mechanical better future.
