Large Consumer Unit Main performance characteristics
1 Auxiliary circuit has the functions of local, remote, automatic and local and remote switching, and the contactor can adopt DC hold. The operating voltage is AC 220V and the signal current is 6A;
2 The power receiving main switch has optional instantaneous tripping and thermal magnetic tripping protection. In order to cooperate with the lower-level main switch, the instantaneous protection is cancelled, avoiding over-level tripping, and has self-turning, non-self-turning and switching devices for users Select.
3 The motor control circuit has instantaneous short-circuit, overload, undervoltage release and phase failure protection;
4 The AC contactor can be operated silently and has energy-saving functions.
5 The main switch of the feeder circuit has instantaneous tripping and thermal-magnetic tripping protection. When the user requires it, leakage protection can be installed;
6 The main switch of the lighting circuit has instantaneous, overload and leakage protection:
7 The receiving circuit is equipped with ammeter and voltmeter;
8 In the feeder circuit, 250A and above can be installed with or without ammeter and watt-hour meter.
Safety operation specification for distribution box and switch box
1. There should be enough space and passage for 2 people to work at the same time around the distribution box and switch box. Any items that hinder operation and maintenance should not be stacked, and there should be no shrubs or weeds.
2. The distribution box Large Consumer Unit and switch box should be made of cold-rolled steel plate or flame-retardant insulating material, and the thickness of the steel plate should be 1.2-2.0mm. Less than 1.5mm, the surface of the box should be treated with anti-corrosion.
3. The distribution box and switch box should be installed correctly and firmly. The vertical distance between the center point of the fixed distribution box and the switch box and the ground should be 1.4-1.6m. Mobile distribution boxes and switch boxes should be installed on sturdy and stable supports.
The vertical distance between its center point and the ground should be 0.8-1.6m. The electrical appliances (including sockets) in the distribution box and switch box should be installed on the metal or non-wood flame retardant insulating electrical installation board first, and then the whole can be fastened in the distribution box and switch box. The inlet and outlet of the wires in the distribution box and switch box should be located on the bottom surface of the box.
Drawer switch cabinet. This type of switchgear is made of steel plate to make the closed shell, and the electrical components of the incoming and outgoing circuits are all installed in the drawers that can be withdrawn to form a functional Large Consumer Unit that can complete a certain type of power supply mission. The functional unit and the bus bar or cable are separated by a grounded metal plate or a functional board made of plastic to form three areas of the bus bar, the functional unit and the cable. There are also barriers between each functional unit. Drawer type switch cabinets have higher reliability, safety and interchangeability, and are relatively advanced switch cabinets. Most of the switch cabinets refer to drawer type switch cabinets. They are suitable for industrial and mining enterprises and high-rise buildings that require high power supply reliability, as a power distribution center for gathering control.
