Metal Clad Enclosed Low Voltage Power Cabinet/ Switchgear Electrical Equipment Distribution Switchgear Cabinet
GGD AC low-voltage distribution cabinet is suitable for power distribution system of AC 50 Hz, rated working voltage 380 V and rated working current 3150 A in power plants, substations, and industrial enterprises, etc. It is used as lighting, electric energy conversion, distribution and controlling of distribution equipment. GGD AC low-voltage distribution cabinet is designed according to senior management of energy ministry, general electric power
users and requirements of design department. The device is a innovative type of low-voltage distribution cabinet that is in line
with the safety, economic, reasonable and reliable principles. The product has high capability of breaking, high thermal stability,
flexible electrical scheme, convenient combination, seriation, high practicability, innovative structure, high protection grade, etc.
It can be used as the upgraded replacement of the low voltage complete switchgears. The device conforms to IE439 < Low-voltage complete switchgear and control equipment >, GB7251 < Low-voltage complete switchgear> standards.
1.Good quality with reasonable price, free sample, punctual delivery, excellent service
2.The part through the process of CNC punching,bending,polishing and packing.
3.Various type of Surface treatment: powder painting, zinc plating, mirror polished, liquid printing or as customer's requirement.
4.Standard/Specification: according to customer's drawing or samples;
5.Material: Cold rolled steel/Hot rolled steel/Stainless steel/ Aluminum/ Copper
1). Adopting panel-division design, flexible equipment of charging cabinet and distribution cabinet, easy to charge;
2). Adopting intelligent high-frequency switch charging module, advanced technique and high reliability;
3). Providing dual-circuits alternating-current input interface, capable of accomplishing dual-circuits alternating-current input main and standby automatic switching and locking;
4). High charging efficiency, small volume, steady product quality, excellent performance;
5). The charger adopting intelligent module design, easy to connect with automation system; has function of self-protection;
6). The module equipped with alternating current under-voltage protection and AC phase-lack protection to realize alternating-current side protection; the module can recover normal working state when input is normal; besides, the module is equipped with lightning protection to realize slow starting function and slow function;
7). Over-voltage protection: the module inputting voltage, capable of automatically turning off machine, to realize load-side protection; the over-voltage protective point of 220V module is 320V±5%, while 110V module is 160V±5%;
8). Short-circuit protection : when short-circuit fault occurs in module input, the output voltage of module fall to 0V and input current lower 15% than rated current; when fault is solved, the module can work again;
9). Over-temperature protection: when radiator temperature detected by module exceeds to 85°C, the system automatically turn off machine; and when the temperature recover to normal scope, the module can work again;10). module connection in parallel protection: the module is equipped with circuit in parallel inside; it can automatically log out system when fault occurs, and has no effect on other modules.
