Description

Technical Field

[0001] The invention relates to the technical field of auxiliary equipment for distribution cabinets, in particular to a distribution board mounting bracket. Background Art

[0002] With the continued growth of power generation in my country, electricity is being used more widely in various areas of production and daily life. Electrical equipment is constantly being updated, and control methods are also constantly adopting new technologies and models as people's concepts improve. In this context, people need to continuously design and manufacture control cabinets that adapt to new equipment. As the core component of control cabinets, the importance of the switchboard is self-evident.

[0003] Since each electrical cabinet has different functions and controls different systems, the components and circuits on the panels are different. Therefore, distribution boards cannot be produced uniformly on an assembly line and can only be manually assembled by operators.

[0004] During the manual distribution process, the following problems exist: for smaller distribution boards, they are usually placed on a workbench about 0.6 meters high, and workers need to sit or stand to operate them. When sitting, in order to connect the lines far away from themselves, the operator needs to lean forward; when standing, they need to bend over, and long-term operation can easily make people tired. When distributing larger distribution boards, they often install the board on the cabinet first, and then sit or stand to distribute them. At this time, they will be blocked by the sides and doors of the cabinet, making operation inconvenient.

[0005] In addition, these two configuration methods have a common disadvantage: when it is necessary to connect wires or adjust the position of electrical component rails and terminal blocks on the back of the panel, the panel needs to be turned over or moved around to the back of the cabinet, which is very inconvenient. This configuration method not only makes the operator's labor intensity high and the work efficiency low, but also when configuring a large panel, if there is no door at the back of the cabinet, the position of the electrical component rails and terminal blocks needs to be accurately determined in advance. Once the control components interfere with each other, the panel needs to be removed to adjust from the back, which increases the difficulty of rework.

[0006] Based on this, it is necessary to propose a distribution board bracket. Summary of the Invention
