Drawer type switch cabinet adopts steel plate closed shell, the electrical components of the incoming and outgoing circuit are all in the drawer, forming a functional unit that can complete a certain power supply task. The functional unit is separated from the bus or cable through a grounded metal plate or plastic functional plate to form three areas: bus, functional unit, and cable. There are also barriers between each functional unit. Drawer - type switch cabinet has high reliability, safety and interchangeability. It is a relatively advanced switch cabinet. Now the production of switch cabinet is mostly drawer type. It is suitable for centralized control distribution center in industrial and mining enterprises and high-rise buildings that require high power supply reliability.
Cable: Usually consisting of several wires or groups of wires.
Busbars are products made of highly conductive copper (copper rod) and aluminum, used to transmit electrical energy, with the ability to collect and distribute electrical energy. A dominant body used to transmit electrical energy in a power station or substation. Through it, the electrical energy output from generators, transformers or rectifiers is sent to each customer or other substations. Mathematically, it refers to a straight line that moves in a plane according to certain conditions.
The cable connection mode of high and low voltage cabinet of drawers is as follows:
1, cabinet measurement. The cabinet body of mural ark can be a wall or interlayer, in order to assure the use of the space is not out of shape, but must fluctuation level, both sides is straight. If there is error, it is required that the height difference between the left and right sides of the hole is less than 5mm, and the bottom wheel of the wall cabinet door can make up the error through the debugging system.
2. Track equipment. When making cabinets, you must reserve dimensions for the tracks. Upper and lower track reserved size folding door is 8cm, sliding door is 10cm.
3. Spacer bar equipment. Drawers are generally designed for domestic cabinets. In order not to affect the use, should pay attention to the position of the drawer: the production of three sliding doors, should avoid the intersection of two doors; When making two sliding doors, the drawer should be placed on one side of the door body; When making folding doors, there should be a 17cm gap between drawers and side walls.
4, cabinet door equipment. The process is: fixed top rail, track front surface and cabinet surface in the same plane, the upper and lower rail level placed in the reserved position; Then load the two doors into the track, measure the straightness of the door body with a level or ruler, adjust the upper and lower direction of the track and fixed; Check whether the door body is parallel to both sides again, adjust the door body by adjusting the bottom wheel, so that it reaches the level of the frame and both sides; Place anti-jump equipment and show quality protection certificate.
