Electrical switchboard is a electrical panel,it is composed of main circuit breaker,Curent transformer,relay,isolators, voltmeter,busbar ,switch disconnect devices.
The functions of switchboard
The rated current of the low voltage Switchboard cabinet is an AC50HZ, rated voltage 380V distribution system.
The main function is to distribute power,the voltage through the transformer is distributed to each power unit,used for power and lighting distribution in the low voltage distribution system.
1. It is convenient for reasonable configuration of power supply.
2. When a fault occurs on the line, it is helpful to control the fault range and it is convenient to quickly find the fault point and eliminate it in time.
3. It is convenient to arrange the line maintenance for slicing without the need of large-scale blackout.
4. It is convenient to arrange various protective devices such as fuses to prevent short circuit and air switches to prevent overload in the distribution cabinet.
