Description

Technical Field

[0001] The utility model relates to the technical field of switch boxes, in particular to a high and low voltage switch cabinet with automatic lifting and lowering adjustment functions. Background Art

[0002] High-voltage switchgear is widely used in 35kV and below systems due to its compact structure, small footprint, and convenient operation. In order to ensure reliability and safety, the switchgear is generally connected with a closed busbar bridge, which has a high degree of closure, compact structure, and small internal space. The relatively closed air circulation is not smooth, and moisture often enters due to poor sealing and underground moisture. When the air humidity is too high, condensation is easy to occur in the cabinet, causing the insulation parts to be damp, which reduces the performance and life of the components, accelerates metal corrosion, oxidizes the contact surface, and increases the contact resistance, resulting in a serious decrease in the insulation strength of the high-voltage electrical equipment, which in turn leads to accidents. Therefore, moisture-proof and dehumidification have become important factors to ensure the safe and stable operation of the switchgear. In addition, the main function of the switchgear is to generate a lot of heat in the process of power generation, transmission, distribution and power conversion in the power system, so that the temperature inside the cabinet remains high, which causes the insulation parts to melt or break over time, and even worse, the air intake circuit catches fire, causing a fire.

[0003] Announcement CN215645688U authorizes a high and low voltage switch cabinet with automatic lifting and adjustment functions. In order to solve the problem that when the existing underground switch box is lifted out of the ground and the lifting outlet is blocked by foreign objects, the staff cannot be notified in time. A switch cabinet door is installed at the front end of the main cabinet, a connecting pin is installed on one side of the switch cabinet door, an acrylic observation window is installed at the front end of the switch cabinet door, a switch cabinet door handle is installed at the front end of the switch cabinet door, a drainage ceiling is installed on the upper end of the switch box device body, and a wireless signal transmission mechanism is installed on the upper end of the drainage ceiling to solve the problem encountered when the buried switch cabinet is lifted.

[0004] However, the above and other typical existing technologies still have certain problems when used:

[0005] 1. The internal space of the switch cabinet is small and relatively closed, with poor air circulation. Moisture often enters due to poor sealing and underground moisture. Water vapor accumulates inside the cabinet, which easily causes condensation, causing the insulating parts to become damp, reducing the performance and life of the components, accelerating the corrosion of metal wires and casings, and causing the service life of high-voltage electrical equipment to be seriously reduced, and even accidents may occur.

[0006] 2. The switch box will transmit and distribute electricity, convert high and low voltage, and convert electric energy during use. At the junction of the wires, a large amount of heat will be generated due to the thermal effect of the current. The heat will accumulate in the closed and narrow space, and the temperature will continue to rise, which will cause the insulation parts to melt or break, and even worse, the intake circuit will catch fire, causing a fire.
