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, lighting heating! Figure can be left to right, the first following a one contact and coil miss, Zhengzhou low voltage switch cabinet principle, we can see loop number (Menu distinction), such as current is A, B, low voltage switch , C, N421, positive supply 1, Taikang low voltage switch cabinet, the negative power supply 2 and the like, it is easy to thermal control power supply cabinet detailed thermal control power supply cabinet should be at least 2.0 enclosed sheet metal all welded construction, sheet metal thickness mm. tank top with a removable rings should thermal control power supply cabinet with bottom inlet line, Huixian low voltage switch cabinet, front door type, power supply cabinet can be installed separately to be installed in groups, against a wall. heat control power cabinet according to protection class IP54. Changge low voltage low voltage switch cabinet _ _ Xi Xi promise electromechanical provided by Connaught Mechanical and Electrical Equipment Co., Ltd., Henan.
