产品简介： |
|
| GGD-H type low-voltage distribution cabinet is according to the requirements of the Ministry of energy, vast power users and design department, with the purpose of safe, economic and reasonable, reliable principle and joint design of new type low-voltage distribution cabinet. It is widely used in power plants, substations, industrial enterprises, high-rise buildings, hospitals, schools and other power users of AC 50Hz, rated voltage is 380V, the distribution system of rated current up to 3150A, electricity as power, lighting and power distribution equipment can conversion, distribution and control of use. | |
产品特点： |
|
| A .product has the advantages of large capacity, high breaking capacity, dynamic thermal stability, high degree of protection, novel and reasonable structure, electrical scheme is practical, flexible, convenient combination of series of wide, strong practicability and the like, can be used as a renewal product. B cabinet frame using 8MF material assembly and, with 20mm modulus of the mounting hole, the general coefficient is high; cabinet under both ends of different amounts of heat dissipation holes, when the cabinet, electrical heating element, heat up, is discharged through the upper end of the groove hole, and cold constantly from the bottom slot supplement into the ark, the sealed cabinet body from bottom to top form a natural ventilation, so that cooling effect good. C main circuit scheme including: overhead power cable, a standby power by electricity, contact, air feed switch, fuse knife switch feed, limit flow switch air feed, feed contactor, fuse for feeding, lighting, reactive power compensation etc.. D 具有可靠的接地保护系统，柜门、电器元件框架及操作手柄通过裸铜软导线与柜架或地排可靠连接，柜架通过地脚螺丝、地排与地极可靠连接。 D with reliable grounding protection system, cabinet, electrical appliance component frame and an operating handle through the bare copper soft wire and cabinet or row of reliable connection, cabinet frame through bolts, row reliably connected with the ends of the earth. | |
