Energy Saving Customized Transformer Cabinet Low Voltage Electrical Power Distribution Switchgear

Welcome to our homepage to see more content!Product DescriptionProduct InformationHigh/Low voltage switchgear refers to the electrical products used for power system generation, transmission, distribution, power conversion and consumption to play the role of on-off, control or protection, voltage level in 3.6kV~550kV, mainly including high/low voltage isolation switch and ground switch, high voltage load switch, high voltage automatic recirculation and sectioner. High voltage operating mechanism, high/low voltage explosion-proof distribution device and high voltage switchgear and other categories.The switchgear has the functions of overhead inlet and outlet line, cable inlet and outlet line, and busbar connection. It is mainly used in power plants, substations, petrochemical industry, metallurgical steel rolling, light textile industry, factories and mining enterprises, residential areas, high-rise buildings and other different places.The high and low voltage switchgear is an important part of the power system, which is mainly used to break the circuit, protect the power equipment and control the power system. The following is the main role of high and low voltage switchgear: 1. Disconnect the circuit The high and low voltage switchgear can successfully perform the switching operation of the circuit breaker, that is, the switchgear can separate or connect the power supply by controlling the switch, and ensure the continuity of power transmission while maintaining the safety of the circuit and equipment. 2. Protect power devices In the power system, the transmission process of high-voltage power supply will produce various faults, such as overload, short circuit and ground fault. The high voltage switchgear can choose the appropriate protection device according to the actual situation, detect and deal with these faults in time, and ensure the normal operation of the power equipment. 3. Control the power system The high and low voltage switchgear can control the switch and state of the power equipment according to the actual needs of the power system. For example, when controlling the power system in real time, it is necessary to precisely adjust the transmission and distribution of power, and the high and low voltage switchgear can achieve this by controlling the switch.Product DetailsHigh/Low voltage switchgear is usually composed of switchgear, meters, control appliances, insulating parts, connecting parts, mechanisms, enclosures and bases. Switchgear is the core component of high voltage switchgear, it is to achieve high voltage line switching, disconnecting and load switching equipment, according to different uses can be divided into circuit breakers, load switches, combined electrical appliances, grounding switches and so on. Instrument is used to display the operating status of the switch cabinet equipment, such as ammeter, voltmeter, indicator light, etc. Control appliances are devices used to control the operation of the switch cabinet, such as control buttons, relays, remote controls, etc. Insulation parts are used to isolate the parts between electrical equipment, such as insulation board, insulation column, etc. Connecting parts are used to connect electrical equipment between the parts, such as conductive strips, patch panels, etc. A mechanism is a component used to realize the action of a switching device, such as a manual mechanism, an electric mechanism, etc. The shell is used to protect the parts of the equipment inside the switch cabinet, such as the steel plate shell, protective cover, etc. The base is used to support the switch cabinet components, such as steel plate base, Angle iron base, etc. The main materials used are as follows: 1.Cold-rolled steel or Angle steel (for welding cabinets); 2.Aluminum coated zinc steel or galvanized steel (for assembly cabinets). 3.Stainless steel plate (non-magnetic). 4.Aluminum plate ((non-magnetic). 5.The functional unit of the cabinet 6.Main bus room (General main bus layout according to the "product" shape or "1" shape of two structures 7.Breaker room 8.Cable house 9.Relay and instrument room 10.Cabinet top small bus roomProduct ParametersHigh/Low voltage switchgear quality control:The manufacturing of high/low voltage switchgear needs to be carried out in strict accordance with national standards, and quality control is required.In manufacture in the process, materials, components, assembly, welding, insulation treatment, electrical testing and commissioning are required quality control.At the same time, it is also necessary to carry out inspection, testing and acceptance.HXGN  -12 High Voltage SwitchgearItemUnitDataRated Voltagekv12Rated FrequencyHz50Rated Current of Main Busbar/Maximum Rated Current of FuseA630,125Rated Short-time Withstands Current of Main Loop and Grounding LoopKA/s20, 3Rated Peak Withstand Current of Main Loop and Grounding LoopKA50Rated Shot-circuit Closing Current of Main Loop and Grounding LoopKA50Breaking Times of Load swit
