The general principles for the installation and use of low voltage electrical appliances are:
1. Low-voltage electrical appliances should be installed vertically. Especially for oil-immersed decompression starters. In order to prevent the insulation oil from overflowing, the tank should not be inclined more than 5. It should be bolted to the support and should not be welded: the installation position should be easy to operate, and the handle should be kept at a certain distance from the surrounding buildings. Not easy to be damaged.
2. Low-voltage electrical appliances should be installed at an appropriate height from the ground in places where there is no severe vibration. Power lines such as knife switches and load switches must be connected to fixed contacts. Do not attach the power cord to the knife switch.
3. The metal casing or metal bracket of the low-voltage electrical appliance must be grounded (or connected to zero). The bare part of the appliance should be equipped with a protective cover. The opening position of the double-throwing switch should have a device to prevent self-closing.
4. In the workshops with flammable, explosive gas or dust, the electrical appliances should be sealed and installed outdoors, and there are rainproof measures. Explosion-proof electrical appliances must be used in places with explosion hazards.
5. When using, the surface of the electrical contact should be clean, smooth and well contacted. The contact should have sufficient pressure. The action of each phase contact should be consistent, and the arc extinguishing device should be kept intact.
6. Before use, the protective oil layer on each contact surface should be removed. Before the operation, the operator should operate several times to check the operation. The static contact of the low-voltage electrical appliance should be connected to the power supply, and the moving contact should be connected to the load.
7. The single pole switch must be connected to the phase line. Low-voltage electrical appliances installed on the floor. The bottom should be 100mm above the ground. On the surface of the low-voltage electrical installation, the name of the installation equipment and the circuit number or road number should be indicated.
