KYN61-40.5 High voltage switchgear 303 PT cabinets

Switchgear Type

Classified by voltage level: It can be divided into high-voltage switchgear (used for voltage levels of 1kV and above) and low-voltage switchgear (used for voltage levels below 1kV).

Classified by Applications: There are incoming switchgear, outgoing switchgear, metering switchgear, capacitor compensation switchgear, etc. Incoming switchgear is used to receive power supply; outgoing switchgear distributes power to various power-consuming equipment or branches; metering switchgear is mainly used for power metering; capacitor compensation switchgear is used to improve the power factor of the power system and reduce reactive power loss.

Classified by structural form: There are fixed panel switchgear, drawer-type switchgear, and combined switchgear, etc. Fixed panel switchgear has a simple structure and a low Price, suitable for places with low space requirements and infrequent operation; drawer-type switchgear has high safety and flexibility, electrical components are installed in drawers, which is convenient for maintenance and replacement, suitable for places with high requirements for power supply reliability; combined switchgear combines various functional units, which can be flexibly configured according to actual needs.

Components

Switching devices: such as circuit breakers, isolators, load switches, contactors, etc., used to connect and disconnect circuits, control power distribution and equipment operation.

Protective devices: including fuses, thermal relays, overcurrent relays, undervoltage relays, etc., automatically cut off the circuit when the circuit has overloads, short circuits, undervoltage, etc., to protect equipment and lines.

Measuring instruments: such as voltmeters, ammeters, wattmeters, electricity meters, etc., used to measure various electrical parameters in the circuit to monitor the operation status of the power system.

Busbars: used to connect various electrical components, collect and distribute power, usually made of copper or aluminum rectangular or circular conductors.

Cables and wires: used to transmit power, connecting the switchgear to the power supply, power-consuming equipment, etc.

Cabinet: As the outer shell of the switchgear, it protects internal electrical components, isolates live parts, prevents interference from external factors, etc., usually made of metal materials, with good mechanical strength and protective performance.

Installation and Maintenance

Installation: The switchgear should be installed in a dry, well-ventilated place without corrosive gases and dust. The installation location should be convenient for operation and maintenance. During installation, ensure that the cabinet is well grounded, the installation of various electrical components is firm and reliable, and the Specification and laying method of connecting wires meet the requirements.

Maintenance: Regularly clean the switchgear, remove dust and debris; check whether the connections of various electrical components are loose, whether there are abnormal phenomena such as heating and sparking; check whether the switch operation is flexible, and whether the setting value of the protection device is correct; regularly check the insulation of busbars and cables to ensure good insulation performance.
