Description

A small power distribution cabinet that is convenient to move

technical field

The utility model relates to an electric power device, in particular to a small-sized power distribution cabinet which is convenient to move.

Background technique

Power distribution cabinet requires to be assembled in closed or semiclosed metal safe by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution cabinet. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. The main function of the power distribution cabinet is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system.

The power distribution cabinet should have a reasonable distribution of electric energy to facilitate the opening and closing of the circuit. It has a high level of safety protection and can intuitively display the conduction state of the circuit. It is easy to manage, and it is convenient for maintenance when a circuit failure occurs. Usually, the power distribution cabinets used outdoors are closed, with poor heat dissipation and communication performance, and cannot be used in occasions that require good heat dissipation and remote control. When the temperature inside the box When it reaches a certain height, the components inside the box will be damaged due to the poor heat dissipation effect, which reduces the practical performance, improves the maintenance rate of the power distribution cabinet, and increases the maintenance cost. Power distribution cabinets often need to be moved frequently because of different application occasions, especially relatively small power distribution cabinets, which are more frequently moved. Some power distribution cabinets are equipped with wheels under the cabinet body, but the positioning is not reliable after use, resulting in There will be movement, which cannot meet the needs of use. At the same time, when the power distribution cabinet is used, it is often equipped with an observation window on the cabinet door, so that the internal operation can be observed without opening the cabinet door when it is working. At present, the observation window on the traditional power distribution cabinet door is Open a rectangular hole on the cabinet door, install a bracket on three sides of the hole by welding, the bracket and the wall plate of the cabinet door form a U-shaped groove, and then install a piece of tempered glass from the hole The edge of the bracket is pushed in, and finally screwed into the hole on the bracket to press the toughened glass to form; this kind of observation window has a complex structure, and also needs to be made on site, and the manufacturing and installation process is complicated and the cost is high.
