Radiator for high-voltage switch cabinet

Abstract

The invention discloses a radiator for a high-voltage switch cabinet. The radiator comprises a top plate, a first side plate, a second side plate and a bottom plate. The bottom ends of the first side plate and the second side plate are fixed to the top of the bottom plate, and a closed bin body is formed among the top plate, the first side plate, the second side plate and the bottom plate. First heat dissipation plates are installed on the outer side of the first side plate and the outer side of the second side plate, second heat dissipation plates are installed on the outer side of the top plate, the number of the first heat dissipation plates and the number of the second heat dissipation plates are both multiple, and first convection channels are formed between the adjacent first heat dissipation plates and between the adjacent second heat dissipation plates. The radiator can be matched with a high-voltage switch cabinet, high-efficiency heat dissipation is achieved, and the requirement of the high-voltage switch cabinet for a large carrying current is met. The influence on the load of the high-voltage switch cabinet is avoided, and the service life of the high-voltage switch cabinet is prolonged. The problem of temperature rise of high-voltage switch cabinet high-current products is effectively solved, and heat dissipation and cooling can be effectively carried out.

Description

technical field [0001] The invention relates to an auxiliary device for a high-voltage switch cabinet, in particular to a radiator for a high-voltage switch cabinet. Background technique [0002] High-voltage switchgear refers to the role of on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption. High-voltage switchgear is used as electrical products with a voltage level of 3.6kV ~ 550kV, high-voltage isolating switch and grounding switch, high-voltage load switch, high-voltage automatic reclosing and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and high-voltage switchgear. category. The switch cabinet has functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines, and bus connection. It is mainly applicable to various places such as power plants, substations, petrochemicals, metallurgical steel rolling, light indus...

AI Technical Summary

Problems solved by technology

[0003] However, when the existing high-voltage switchgear is in use, it will generate a lot of heat, which needs to be discharged or exported in time, otherwise the working environment in the high-voltage switchgear will be deteriorated, and the components cannot be effectively protected. It will also affect the load of the high-voltage switchgear, which will bring great safety hazards and affect the service life of the high-voltage switchgear; moreover, the high-voltage switchgear and high-current products of high-voltage switchgear have the problem of temperature rise, and the existing high-voltage The radiator of the switchgear cannot effectively solve this problem, and the cost is high, the heat dissipation effect is poor, and the processing is very complicated, which cannot meet the needs of the large current carrying current of the high-voltage switchgear
