Technical field

The utility model belongs to the technical field of high and low voltage equipment, and specifically relates to a high and low voltage switch equipment with a protective structure.

Background technique

High and low voltage complete sets of equipment are mainly used for the control and protection of power systems (including power plants, substations, transmission and distribution lines, industrial and mining enterprises, etc.). They can either put some power equipment or lines into or out of operation according to the needs of power grid operation, or can When power equipment or lines fail, the faulty part is quickly removed from the power grid, thereby ensuring the normal operation of the fault-free part of the power grid and the safety of equipment and operation and maintenance personnel.

The utility model patent with patent application number CN202220314314.9 discloses a high and low voltage switchgear with a protective structure, including a protective part and a lighting part; the protective part includes a cabinet, a cabinet door, a first protective box, a first protective Door, guide rod, limit rod, slider, second protective box, second protective door. The cabinet door is hinged with the cabinet body. There is a partition inside the cabinet, and there is a partition on one side of the partition. The connecting block of this utility model has a simple structure. By being provided with a protective part, it can play a double protective role on the internal electrical components. By being provided with a lighting part, it can illuminate the maintenance personnel during maintenance under poor light conditions, eliminating the need for maintenance. The personnel hold the lighting equipment and can adjust the direction and position of the light, which improves maintenance efficiency.

The high and low voltage switchgear with the protective structure in the above patent can, for example, provide lighting for maintenance personnel during the operation of high and low voltage equipment, without the maintenance personnel needing to hold the lighting equipment, and can adjust the direction and position of the light, which improves maintenance efficiency. However, When the equipment is used for a long time or frequently tested, due to the use of multiple layers of protection systems and the lack of effective heat dissipation system solutions, the internal temperature of the electrical box may be too high after the equipment has been working for a long time, which may easily cause damage to the equipment. Due to overheating, the efficiency will decrease, and the line may even be damaged, which has a greater risk. For this reason, we have a high and low voltage switchgear with a protective structure, which will use dustproof shells to be placed on both sides of the fan to protect it. It can not only effectively dissipate internal heat, but also effectively prevent external dust from being sucked into the inside of the electrical box to cause dust accumulation. The refrigeration equipment also cools down the capacitor assembly and high and low voltage switches, which not only maintains the power for a long time. The temperature inside the box is at low temperature, and can effectively reduce the load caused by using the fan alone. It effectively ensures that the electrical box can be in a benign long-term low temperature state, so that the equipment can maintain normal operation for a long time and improve the work efficiency of the equipment. and improved security.
