GCK drawer switchgear cabinet GCK (1A) Low-voltage switchgear cabinet drawer for three-phase AC 50,60HZ, rated working voltage 380V, rated current 4000A and below the three-phase four-wire and three-phase five-wire power system, widely used in communications centers power plants, substations, industrial and mining enterprises, building hotels, airports, terminals and radio and television, transmission and distribution, power conversion and power consumption of the PC power distribution and motor control centers MCC. Use of environmental conditions 1, ambient air temperature is not higher than + 40 ℃, not lower than -5 ℃, and within 24 hours the average temperature does not exceed + 35 ℃. 2, ambient air temperature is + 40 ℃, relative humidity less than 50%, at a lower temperature allows a higher relative humidity, such as + humidity allowed 90% 20 ℃ when, but should take into account changes in temperature It may produce condensation. 3, the indoor use, the use of location altitude must not exceed 2000M. 4, should be installed in the absence of severe vibration and shock, and enough to make electrical components from corrosion places. Structural features of the basic framework for the GCK assembled structure, all structural parts have been galvanized cabinet, spray, connected to each other by fastening screws into the basic cabinet, and then need to add doors, baffles, partitions pumping flexor, mounting brackets and busbars and electrical components and other parts, assembled into a complete control center cabinet. The cabinet structure has the following features. 1. Shelves Shelves with C profiles assembled, cabinet supporting parts and special parts from the companies supporting the supply, ensure the accuracy and quality of the cabinet. a. molding size parts, hole size, spacing implement modular equipment. (Modulus E = 20mm, the same below). b. Internal structural parts are galvanized. c. cabinet removable cover that can be folded, removed the four corners of the roof can be very countertops with rings for lifting and loading. . d External by phosphate treatment; and electrostatic epoxy powder coating. e. Guijia into bus room, functional unit room, cable room three isolated intervals to prevent accidents and to facilitate the diffusion charging maintenance. 2. functional unit (drawer part) a functional unit: feeding unit, motor unit, utility power unit. b. pumping flexor unit height modulus of 200mm, divided 1/2 unit, l unit, 1.5 unit, Unit 2, Unit 3, five dimensions of campaign. Unit circuit rated current 630A or less. e. Each MCC cabinets can be installed up to a unit of nine or 18 1/2 smoke fart pumping unit flexor. f. compartment door and drawer by the operating mechanism of mechanical interlock main switch, the main switch in the closing position, the drawer can not be withdrawn. g. The operating mechanism of the main switch can be used to lock a padlock in the closing or opening position for maintenance of electrical equipment safely. h. the functional units on the back with a main circuit bursts cord, plug the second auxiliary circuit and grounding plug. i. grounding plug connected to pumping flexor connection position in the separation test, to ensure the continuity of the protection circuit. j. functional unit using a metal partition separating the compartments. k. compartment valve, push and pull-out drawer with automatic open and close, so that in the compartment does not touch the vertical bus. l. flexor pumping unit with a rotary feed mechanism stalls, with three-position function, simple and reliable operation. m. drawer drawer operating mechanism described Promotion Organization (hereinafter referred to as the agency) is the use of spacer screws rotating movement along the track, to achieve a functional unit of advancing and withdrawing, the functional unit of advancing and withdrawing the process, to achieve three-position indicator and the mechanical interlocking and feature retrograde position micro switch test electrical interlock to prevent personal or equipment accidents, in line with national and industry standards. The products are small, flexible installation Wan style. Reliable performance. 3. The bus system a. Vertical bus using polycarbonate plastic shell closed. b.GCK, GCL bus system uses a three-phase four-wire, three-phase five-wire system, the level of bus installed on the Roof, N line, PE lines either installed on the Roof, to be installed in the lower cabinet. c. Three-phase horizontal bus copper bus bar, high mechanical strength, good heat dissipation. Mainly used for floor distribution system, basement heating system distribution system. Which sells low-voltage distribution systems, GGD main distribution cabinet, GCK, GCS drawers, MNS drawers, the company has passed ISO9000 certification, CCC certification, please contact us.
