GCK low-voltage withdrawable switch cabinet is widely used in power plants, substations, factories and mines and high-rise building power distribution center PC and motor control center MCC, as AC 50-60Hz, rated voltage is 660V and below, rated current is 4000A and below power distribution and motor centralized control in power generation and power supply systems, and low-voltage power distribution devices for reactive power compensation. Xiao Bian today brings the characteristics of low-voltage withdrawable switchgears , hoping to bring you help!
(1) The cabinet frame is a type of general cabinet. It is made of a new type steel bolted assembly. It has high installation accuracy, easy assembly, high strength, and durability.
(2) The grounding metal separator is used to divide the switchgear into busbar rooms, functional unit rooms, and cable compartments. The functional unit rooms are also isolated from each other by grounded metal plates, which do not interfere with each other and can effectively prevent the expansion of the fault.
(3) The drawer unit has a reliable mechanical interlocking device. Through the control of the operating handle, there are five obvious positions of turning on, off, testing, isolating and withdrawing. When the drawer is pushed and pulled to connect, disconnect, test, isolate In the position, the drawer is automatically positioned and locked, and the position can be moved to the next position.
(4) Drawers with the same rating and structure have good interchangeability.
(5) There are many power supply circuits, which can be flexibly combined and economical and practical. A cabinet can be configured with 9 drawers for 1 unit, or 18 drawers for 1/2 unit.
(6) There are 32 and 64 pairs of auxiliary contacts in the drawer unit (20 pairs of 1/2 drawers), which can meet the needs of automation and computer interface.
(7) The air gap and creepage distance of the electrical components in the cabinet are large, and the insulation strength of the switch cabinet is high.
(8) High-tensile strength insulators are used in the cabinet to enhance the strength of the fixed support of the cabinet and busbar system and to improve the dynamic stability.
(9) The horizontal busbars of GCS cabinet are arranged in the busbar compartment behind the cabinet.
(10) The cabinet structure may consider cables entering the cabinet from the bottom of the cabinet and/or the top of the cabinet.
(11) The configurable intelligent interface device can be directly connected to the fieldbus or connected to the DCS Ethernet via an adapter. Monitoring at the operator station not only improves the level of monitoring automation, but also saves a large number of control cables and reduces investment.
(12) The cabinet has a high degree of protection and can meet the user's high degree of protection.
The above information about the characteristics of the low-voltage withdrawable switchgear was briefly introduced here. Did you have a new understanding after reading this article? More home improvement knowledge, please pay attention to this site information!
