GCK/GCS/MNS low-voltage withdrawable switchgear (hereinafter referred to as switchgear) consists of power distribution center (PC) cabinet and motor control center (MCC). The device is suitable for control and distribution systems with AC 50(60)HZ, rated working voltage less than or equal to 660V-690V, rated current of 4000A and below (among which the rated current of MNS cabinet can reach 6300A), as power distribution, motor control and lighting and other power distribution equipment.
The switchgear meets the needs of various power supply and distribution, and can be widely used in various low-voltage power distribution systems such as power plants, substations, industrial and mining enterprises, buildings, hotels, municipal construction, etc. ", GB/T 7251-2017 "Low-voltage switchgear and control equipment" and other standards.
High degree of standardization: reasonable structure, flexible scheme, strong versatility, and meet the standardization design of power grid;
Modular design: easy to expand, the cabinet accommodates a large number of circuits, the overall use of the assembled structure, the module hole installation, the general performance of the parts and components, saves floor space, and is convenient for maintenance, the top of the switch cabinet is based on the needs of electricity Bus bridge can be installed;
Safe and reliable: The upper part of the cabinet is the busbar room, the front part is the electrical room, and the rear part is the cable entry and exit room. Each room is isolated by steel plates or insulating plates to ensure safe operation;
Advanced structure: The door of the drawer compartment of the MCC cabinet is mechanically interlocked with the operating handle of the circuit breaker or isolating switch, and the door can only be opened when the handle is in the breaking position; the drawer of the power receiving switch, the tie switch and the MCC cabinet has three positions: On position, test position, off position;
Flexible combination: the drawers of the same functional unit have good interchangeability; the drawer unit is the main body, and has both withdrawable and fixed properties, which can be combined and used arbitrarily;
High protection level: The protection level of the cabinet is IP30 or IP40, which can be selected according to user needs.
High degree of intelligence: It can cooperate with the intelligent operation and maintenance background to bring temperature sensing or various states to the background to realize intelligent control;
