MNS low-voltage withdrawable switchgear

Switchgear Type

Classified by voltage level: High-voltage switchgear (used for 1kV and above voltage levels) and low-voltage switchgear (used for below 1kV voltage levels).

Classified by Applications: Incoming switchgear, outgoing switchgear, metering switchgear, capacitor compensation switchgear, etc. Incoming switchgear is used to receive power supply; outgoing switchgear distributes electricity to various electrical equipment or branches; metering switchgear is mainly used for electricity 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 combination switchgear, etc. Fixed panel switchgear has a simple structure and a relatively low Price, suitable for places with low space requirements and infrequent operation; drawer-type switchgear has higher safety and flexibility, with electrical components installed in drawers for easy maintenance and replacement, suitable for places with high power supply reliability requirements; combination switchgear combines various functional units and 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 and control the distribution of electricity and the operation of equipment.

Protective devices: Including fuses, thermal relays, overcurrent relays, undervoltage relays, etc., automatically cut off the circuit when the circuit experiences overload, short circuit, undervoltage and other faults 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 operating status of the power system.

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

Cables and wires: Used to transmit electricity, connecting the switchgear to the power supply, electrical equipment, etc.

Cabinet: Serves as the outer shell of the switchgear, protecting internal electrical components, isolating live parts, preventing interference from external factors, etc. It is usually made of metal material with good mechanical strength and protective performance.

Installation and Maintenance

Installation: The switchgear should be installed in a dry, well-ventilated place free of 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 the connecting wires meet the requirements.

Maintenance: Regularly clean the switchgear to remove dust and debris; check whether the connection of each electrical component is loose, whether there are any abnormal phenomena such as heating or 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 that their insulation performance is good.
