High-voltage switch cabinet with dust removal and heat dissipation functions

Abstract

The invention discloses a high-voltage switch cabinet with dust removal and heat dissipation functions, which comprises a high-voltage switch cabinet body. A dust removal and heat dissipation cabinet seat is arranged below the high-voltage switch cabinet body, a filter cavity is arranged in the dust removal and heat dissipation cabinet seat, and the right end of the filter cavity is provided with a dust suction port communicated with the outside. A detachable filter screen assembly is installed on the inner wall of the first cabinet door, a snakelike sedimentation channel formed by upper flow guide heat dissipation plates and lower flow guide heat dissipation plates in a staggered mode is arranged in the filter cavity, a dust removal chamber is arranged between every two adjacent lower flow guide heat dissipation plates, an anti-static dust collection bag is arranged in each dust removal chamber, and a vacuum pump is arranged at the left end of the filter cavity. The dust removal and heat dissipation cabinet seat is installed at the bottom to remove dust floating into the equipment during heat dissipation of the switch cabinet, multi-stage filtration is realized, and when airflow filtered by the filter screen assembly passes through the snakelike sedimentation channel, not only can heat of the high-voltage switch cabinet be taken away, but also the dust can be settled and collected by using a gravity sedimentation principle.

Description

technical field [0001] The invention relates to a high-voltage switchgear, in particular to a high-voltage switchgear with dust removal and heat dissipation functions. Background technique [0002] As an important equipment in the substation, the high-voltage switchgear plays the role of closing and breaking the power line, which is of great significance to the safe and reliable operation of the power system. The high-voltage switchgear generally has a busbar room, an overvoltage device, a relay instrument room, a disconnector, a circuit breaker room, etc. The frequency of high-voltage switchgear is getting higher and higher, and there are more and more things that need high-voltage control. There are mainly the following problems in the high-voltage switchgear: First, the long-term operation of the high-voltage switchgear will inevitably cause phenomena such as overload operation, and these phenomena will easily lead to an increase in the internal temperature of the switch...

AI Technical Summary

Problems solved by technology

The high-voltage switchgear mainly has the following problems: First, the long-term operation of the high-voltage switchgear will inevitably lead to overload operation and other phenomena, and these phenomena will easily lead to an increase in the internal temperature of the switchgear and hidden safety hazards. If this is not eliminated in time If there are hidden dangers, it is easy to cause an electric fire, so it is very important to ensure the smooth flow of air inside and outside the switch cabinet

Second, under the influence of various factors such as static electricity generated during the use of high-voltage switchgear, it is very easy to accumulate dust inside and outside the high-voltage switchgear, and it is not convenient to clean the dust in time. Seriously affect the use of equipment
