GGD AC low-voltage distribution cabinet ※ PURPOSE: GGD AC low-voltage power distribution equipment for power plants, substations, industrial enterprises and other power users of AC 50Hz, rated working voltage of 400V, low voltage switch cabinet Changge, rated current up to 3200A distribution system, as power, lighting and power distribution equipment, power conversion, distribution and control purposes. GGD AC low-voltage distribution cabinet is in a safe, economic, rational and reliable design principles of new low-voltage power distribution equipment. Products with high breaking capacity, dynamic thermal stability, structure, reasonable, electrical program flexible combination of convenience, family, practical, high level of protection. Low-voltage switchgear as the replacement product. GGD AC low-voltage distribution cabinet meet IEC439 "Low-voltage switchgear and control equipment", GB7251.1 "Low-voltage switchgear and control equipment Part 1: Type tested and partially type test switch equipment" and other standards. ※ Main features: 1, the basic structure of the device to the modular structure, low voltage switch to KS profile (modulus E = 20mm) as the main structure, the use of self-tapping screws and high strength bolts fastening together. Member high versatility, can shorten the production cycle, low voltage switch cabinet Zhengzhou principle, improve work efficiency. 2, the upper and lower ends of the device cooling holes, consider running cooling cabinet components, forming the upper and lower air flow duct, have good heat dissipation. 3, cabinet cover can be removed for easy installation and adjustment of field of the main bus. The basic structure of low voltage circuit breakers low-voltage circuit breaker low-voltage electrical equipment is one of the main power system. Low voltage circuit breaker can be switched on or off under normal load circuit, when a short circuit fault circuit or overload, low-voltage circuit breaker Tripping automatically protect gas lines and electrical equipment effect, expand the scope and prevent accidents . Low-voltage circuits can be used for low-voltage power distribution equipment to do the master switch and branch switches can also be used for infrequent start motor control. First, the basic structure of the low-voltage circuit breaker by low pressure release, contact system, arc system, the transmission mechanism, the base frame and the shell components. 1, the release of the release is the low voltage circuit breakers for receiving component signal. If the situation is not normal or signaled by the operator or circuit protection devices, the trip through the contacts movement transmitting element Tripping signal cut off the circuit according to the situation.
