A high-efficiency heat dissipation type high- and low-voltage electric switch cabinet

Abstract

The invention discloses a high-efficiency heat dissipation type high- and low-voltage electric switch cabinet, comprising a shell and a cabinet door, wherein the cabinet door is hinged on the side wall of the housing through a hinge; the upper end of the shell is fixedly connected with a fixing frame, the upper end of the fixing frame is symmetrically provided with two arc-shaped holes, the motoris fixedly connected with the inner top wall of the fixing frame, a first silica gel cooling fin is added to achieve a heat dissipation effect, the heat dissipation effect of the first silica gel heatsink is improved, and then drives the airflow through the fan blades, the intake pipe cools the air flow, thereby removing heat from the airflow space, to achieve a good cooling effect, a second silica gel cooling fin, a heat dissipation pipe and a connecting pipe are added, the effect of rapid heat dissipation is achieved through water circulation, and the air outlet continuously blows the watersprayed from the atomizing spray nozzle, so that the temperature of the feed water can be quickly lowered, the heat can be quickly dissipated during the water circulation, and the motion of the piston can accelerate the water flow atomization, so that cooling is facilitated.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a high-efficiency heat dissipation type high and low voltage electrical switchgear. Background technique [0002] As the name suggests, the high and low voltage switchgear is a device for connecting high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers to low-voltage cabinets, and then to various power distribution boxes. It is nothing more than electrical equipment that assembles some protective devices such as switch circuit breakers into one. AC low-voltage power distribution cabinets are mostly used in power plants, substations, factories and mines, etc. In the power distribution system with a current up to 3150A, it is used for power conversion, distribution and control of power, lighting and power distribution equipment. The product has high segmentation capacit...

[0002] As the name suggests, the high and low voltage switchgear is a device for connecting high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers to low-voltage cabinets, and then to various power distribution boxes. It is nothing more than electrical equipment that assembles some protective devices such as switch circuit breakers into one. AC low-voltage power distribution cabinets are mostly used in power plants, substations, factories and mines, etc. In the power distribution system with a current up to 3150A, it is used for power conversion, distribution and control of power, lighting and power distribution equipment. The product has high segmentation capacity, good dynamic and thermal stability, novel and reasonable structure, and practical electrical scheme. The series has strong practicability and high protection level, but its structure is compact, and a large amount of heat energy in the equipment gathers when the equipment is running, so the heat dissipation has not been solved well.

[0003] The existing heat dissipation method is mainly to provide heat dissipation holes on the top plate of the switch cabinet, but because the heat dissipation effect of the heat dissipation holes is limited, especially this heat dissipation structure cannot achieve the heat dissipation effect of air convection, so when in use, The temperature inside the switch cabinet is still high,

[0004] A rapid heat dissipation high and low voltage switchgear with the publication number CN206585252U adopts the method of heat dissipation after absorbing heat to dissipate heat, which effectively achieves rapid heat dissipation. way to dissipate heat, the heat dissipation effect is not good
