The Difference Between Switch Cabinet And Power Distribution Cabinet

The difference between the switch cabinet and the power distribution cabinet is as follows: First, the functions are different; the switch cabinet mainly plays the role of opening and closing, and the power distribution cabinet plays the function of distributing electric energy. Second, the external dimensions are different; the power distribution cabinet is small in size and can be hidden in the wall or on the ground, while the switch cabinet is large in size, generally about 180 cm. Third, there are differences in installation sites; power distribution cabinets can be installed in various places, such as schools, factories, hospitals, homes, etc., and switch cabinets are often installed in substations, power distribution rooms, etc.

The difference between switch cabinet and power distribution cabinet is as follows:

1. Different functions, the switchgear is a complete set of switchgear and control equipment. As the power center and the main power distribution device, it mainly plays the role of opening and closing the switch. The power distribution cabinet plays the function of distributing electric energy and protects the line from overload, short circuit and leakage.

2. The dimensions of the switchgear are different, and the size of the switchgear is large, and the height is generally 1800mm, 2000mm and 2200mm. The power distribution cabinet is small in size, generally only the size of a palm, which can be hidden in the wall or on the ground.

3. There are differences in installation sites. Switch cabinets are often set in substations, power distribution rooms, etc. Power distribution cabinets can be installed in various places, such as schools, institutions, hospitals, factories, workshops, homes, etc.

4. The line materials are different. The main line of the switch cabinet is often dominated by copper bars, while there are many wires in the distribution box. ,

5. The components are different. Most of the low-voltage cabinets are molded case circuit breakers and frame circuit breakers, as well as capacitor cabinets. The content in the distribution box is more complicated. The common one is a larger switch with a series of micro-breaks below.

Switch cabinet purchase points are as follows:

1. Choose a well-known brand, because the switchgear is a complete set of combined products. Once technical problems are encountered, equipment maintenance and replacement are more troublesome. Therefore, when the budget is sufficient, you should try to choose a well-known brand. When a well-known brand encounters a problem, the resolution efficiency is relatively high.

2. Before purchasing, ask the manufacturer for the inspection qualification of the switchgear, if not, it is basically an irregular product. Secondly, it is necessary to see whether the components of the switch cabinet are configured according to the drawing requirements.

3. The material of the cabinet should be considered. Generally speaking, the switchgear of good quality, component brackets, etc. are all made of imported aluminum-zinc sheets, while the door panels are made of 300 series high-quality steel plates.

4. Incoming and outgoing lines, the general switch cabinet has two connection ways: one is the connection of incoming and outgoing cables and cable rooms. The other is to first lead the incoming and outgoing wires through the wall bushing on the top of the cabinet, and connect it with the busbar bridge, and then connect it with the overhead line through the wall bushing. If it is the second application, it is necessary to supervise the work on site during installation.
