Intelligent low-voltage power distribution network low-voltage treatment device and use method thereof

Abstract

The invention provides an intelligent low-voltage power distribution network low-voltage treatment device and a use method thereof.The intelligent low-voltage power distribution network low-voltage treatment device comprises an aluminum shielding top plate, an air guide through cavity, a back copper heat absorption plate, a small lead screw, an upper positioning chuck and an upper moving plate, the back copper heat absorption plate is installed on the rear side of the inner wall of a protection box, and the air guide through cavity is formed in the rear side of the interior of the protection box; and an aluminum shielding top plate is installed on the upper side of the annular side face of the supporting stand rod, and the design solves the problem that an original low-voltage line tail end low-voltage treatment device is prone to heat accumulation and rainwater corrosion in the use process, a small lead screw is arranged on the right side in the protection box body, and an upper moving plate is arranged on the upper side of the annular side face of the small lead screw. By means of the design, the problem that an original protection box door is prone to being pried open is solved, and compared with the prior art, the protection box door is reasonable in structure, good in heat dissipation protection effect, capable of preventing the protection box door from being pried open easily and high in use safety.

Description

technical field [0001] The invention is an intelligent low-voltage distribution network low-voltage control device and a method for using the same, belonging to the technical field of low-voltage appliances. Background technique [0002] In the low-voltage distribution network, since most of the power loads are single-phase loads, there are serious three-phase unbalance problems in the low-voltage distribution network. The three-phase unbalanced problem will seriously affect the normal operation of the transformer, for example, it will increase the loss of the transformer, or cause the transformer to be overloaded and burned, etc.; at the same time, the three-phase unbalanced problem will also increase the loss of the distribution line, resulting in serious The line voltage drops, which affects the operation safety of the low-voltage distribution network. With the development of science and technology, the low-voltage distribution network in the existing technology will be ...

Problems solved by technology

[0002] In the low-voltage distribution network, since most of the power loads are single-phase loads, there are serious three-phase unbalance problems in the low-voltage distribution network.

The three-phase unbalanced problem will seriously affect the normal operation of the transformer, for example, it will increase the loss of the transformer, or cause the transformer to be overloaded and burned, etc.; at the same time, the three-phase unbalanced problem will also increase the loss of the distribution line, resulting in serious Line voltage drops, affecting the operation safety of low-voltage distribution network

[0003] However, the existing low-voltage control devices at the end of low-voltage lines have weak self-protection capabilities. Once they are bumped during actual use, they will be damaged, resulting in unnecessary losses. However, some existing protective boxes for low-voltage control devices at the end of low-voltage lines Most of the fans are used for cooling and heat dissipation inside. Although the heat dissipation effect is good, the dust in the external air will also be sucked into the protective box during the heat dissipation process, and the staff needs to clean it, and the existing low-voltage line terminal low-voltage treatment The protective box for the device has no auxiliary positioning structure. Once the criminals pry open the built-in lock on the box door, the box door can be opened easily. method to solve the above problems
