[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a drawable low-voltage complete power distribution cabinet. Background Art

[0002] The rated current of the low-voltage distribution cabinet is AC 50Hz, and the rated voltage of the distribution system is 380v. It is used for power conversion and control of lighting and power distribution. It has the characteristics of strong breaking capacity, good dynamic thermal stability, flexible electrical scheme, convenient combination, strong series and practicality, and novel structure. In the process of low-voltage complete distribution cabinet, it is necessary to pull out the electrical components in the low-voltage complete distribution cabinet for operation. When pulling out the electrical components in the low-voltage complete distribution cabinet, it is necessary to use a withdrawable low-voltage complete distribution cabinet.

[0003] In the prior art, there are the following problems:

[0004] Conventional low-voltage complete distribution cabinets all install and fix electrical components inside the distribution cabinet. The door of the distribution cabinet is opened and closed during use, which makes it inconvenient to operate the electrical components inside the distribution cabinet and also inconvenient to install the electrical components. The existing solution is to set the low-voltage complete distribution cabinet in a pull-out manner, which is convenient for pulling out the electrical components inside the distribution cabinet, and then installing or operating the electrical components. However, the existing distribution cabinets are not convenient for fixing the grooves when pulling out the electrical components, which makes it easy for the electrical components to shake when being manipulated. They do not have the function of automatically shrinking into the distribution cabinet after use. At the same time, after the electrical components are connected, the wires are not clamped and fixed, which makes it easy for the wires to be pulled and fall off when the electrical components are pulled out.
