High Voltage Switchgear schematic diagram how to see if (various programs) is more convenient, you can use the schematic wiring diagram and terminal diagram and control, a look at a circuit, the first AC circuit (such as current and voltage on general schematic loop, current transformers, current protection, metering, etc.), then the DC circuit (control, signal circuit), the last tank circuit, low voltage switch cabinet ShangYinXian principle, lighting heating! Figure can be left to right, the first on the latter, one by one, contacts and coils left off, we can see loop number (Menu distinction), low voltage switch cabinet Yanjin County principle, such as the current is A, B, C , N421, Taikang low voltage switch procurement, positive supply 1, 2, and so the negative power supply, easily topping the cabinet KYN28A-12 details of the cabinet is made of imported aluminum coated zinc plate steel double folded assembled, divided into four separate compartments. meter room and roof design are integrated, the cabinet as a whole simple, reliable, low voltage, easy to install. After two doors up and down the cabinet design, user maintenance more convenient. Secondary go trough optimized design, effectively have to improve the level of protection for the second line. grounding switch central installation, CT lifting, increasing the cable room space, making maintenance simple, easy cable installation can be equipped with VS1, VD4 (ABB), EV12 (Schneider), ZN28 (GM), VB2 (GM), 3AH5 (Siemens) series circuit breaker protection class: shell IP4X, IP2X between compartments of Wugang low voltage switch cabinet principle, learning Connaught Electrical and Mechanical (online. Consulting), low voltage is provided by habit Connaught Mechanical and Electrical Equipment Co., Ltd., Henan. Henan Xi Connaught Electrical Equipment Co.
