Overhead crane load switch cabinets

Switchgear Type

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

Classified by Applications: There are incoming switchgear, outgoing switchgear, metering switchgear, and capacitor compensation switchgear, etc. Incoming switchgear is used to receive power; 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 combined switchgear, etc. Fixed panel switchgear has a simple structure and a lower Price, suitable for places with low space requirements and infrequent operations; drawer-type switchgear has higher safety and flexibility, with electrical components installed in drawers, facilitating maintenance and replacement, suitable for places with high power supply reliability requirements; combined 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, control power distribution and equipment operation.

Protective devices: including fuses, thermal relays, overcurrent relays, undervoltage relays, etc. When the circuit encounters overload, short circuit, undervoltage, and other faults, it automatically cuts off the circuit 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 using rectangular or circular conductors made of copper or aluminum.

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

Cabinet: As the outer shell of the switchgear, it protects internal electrical components, isolates live parts, and prevents interference from external factors. It is usually made of metal materials and has 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 the connecting wires meet the requirements.

Maintenance: Regularly clean the switchgear, remove dust and debris; check whether the connection of each electrical component is loose, and whether there are any 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 the busbars and cables to ensure good insulation performance.
