Distribution boards, also known as distribution cabinets, centralized switching, power distribution equipment. Distribution panel generally consists of cabinet, switches (circuit breakers), protection devices, monitoring equipment, power meters, and other secondary components and parts. Installed in power stations and electricity substations ﹑ large electricity customer. It can be divided in accordance with the current AC and DC distribution panels. It can be divided according to voltage lighting distribution panels and power distribution panels, or high-voltage and low-voltage distribution board panels. It means for low-voltage and low voltage distribution board series lighting, power switch cabinet equipment to reduce the transmission voltage, direct for low-voltage electrical appliances and other equipment, our line voltage supplying electric power transmission are generally based on the distance, using different transmission voltages. 2 Development editors from China's power situation, the use of 220 kV power transmission from the transmission voltage of 200 to 300 kilometers; 110-kV at 100 km; 50 km around the use of 35 kV; 15 km in ~ 10-kilovolt 20 km, the others with 6600 volts. Transmission voltage of 110 kV and above lines, called EHV transmission lines. When long-distance power transmission, as well as our 500 kV EHV transmission lines. China's general low-voltage electricity in 220V, 380V two grades, low voltage distribution boards to install three-phase ammeter and a voltmeter (with the shift voltage switch) is a must, the best choice of the three-phase master switch out of phase automatic circuit breaker (DW10 type ); each phase means low voltage surge arresters (switchboard) to prevent the line being struck by lightning; set an automatic compensation capacitor plate to improve power factor. Low-voltage power distribution room fire resistance rating of not less than three. Distribution room windows should rain and snow, water, small animals of the measures. High and low voltage power distribution equipment in a room at the same distance between them should be not less than 1 meter. Distribution panel generally consists of cabinet, switches (circuit breakers), protection devices, monitoring equipment, power meters, and other secondary components and parts.
