Description

A drawer-type low-voltage switch outlet cabinet

technical field

The utility model relates to a switch cabinet, in particular to a drawer-type low-voltage switch outlet cabinet.

Background technique

Low-voltage switchgear is suitable for power plants, petroleum, chemical industry, metallurgy, textiles, high-rise buildings and other industries. It is used for power transmission, power distribution and power conversion. The fixed type can satisfy the reliable fixing of various electrical components in the determined position of the cabinet. The shape of the cabinet is generally a cube, such as a screen type, a box type, etc., and there are also prisms such as a table type. This kind of cabinet has a single row or arrangement. In order to ensure the shape and size of the cabinet, the components are often combined step by step. Generally, two pieces or the left and right sides are formed first, and then the cabinet is formed, or the shape requirements are met first, and then the cabinet is formed. Secondary connection cabinet internal support. The length of the parts that make up each edge of the cabinet must be correct (the tolerance is negative), in order to ensure the geometric dimensions of all aspects, so as to ensure the overall shape requirements. For the two sides of the cabinet, due to the need for arrangement, there should be no bulge in the middle. In addition, from the perspective of installation, there should be no sinking on the bottom. In the arrangement and installation, the ground level is the prerequisite, but there are certain errors in the dryness and the cabinet itself. In the arrangement, try to offset the lateral difference and not cause the difference to accumulate, because the difference will cause the cabinet to deform. , affect the busbar connection and produce component installation misalignment, stress concentration, and even affect the life of electrical appliances. Therefore, it is advisable to use the highest point of the foundation as the installation reference point when arranging, and then gradually pad and expand the row. Under the condition that the bottom surface is dry and flat and can be predicted, it is also possible to adopt the method of expanding from the middle to both sides, so that the accumulated difference is uniform. cloth.

On the basis of the technical conditions of the existing low-voltage switchgear, there are still many shortcomings in the convenience and functionality of use. Most low-voltage switchgears are inconvenient to install and maintain due to the small internal space during use. , resulting in low work efficiency, which is very inconvenient.
