Problems solved by technology

The disadvantage of this structure is that the low-level air intake is easy to cause tiny obstacles to gather at the air inlet under the action of negative pressure, resulting in the obstruction of the air intake, which in turn affects the heat dissipation of the whole machine; in addition, an additional protective structure needs to be added above the air outlet. Relatively complex and expensive

Abstract

The invention relates to a heat dissipation apparatus for a pole-mounted power active filtering apparatus. The active filtering apparatus comprises a casing, and a main circuit module and a reactor which are installed in the casing. The heat dissipation apparatus employs an up-inlet down-outlet mode and comprises air-intake assemblies, an air isolation plate, cooling fans and an air-out assembly, wherein the air isolation plate is arranged between the main circuit module and the reactor for separating the casing into a first air chamber and a second air chamber, the air-intake assemblies communicate with the air-out assembly through the first air chamber and the second air chamber, and the cooling fans are installed at the two sides of the air isolation plate for performing cooling blowing on the first air chamber and the second air chamber. Compared to the prior art, the heat dissipation apparatus has the advantages of good heat dissipation effect, intelligentization, high safety and the like.

Description

technical field [0001] The invention relates to a heat dissipation device, in particular to a heat dissipation device for an active power filter device on a column. Background technique [0002] Power quality is directly related to the overall benefit of the national economy. Improving power quality is of great significance to the safe and economical operation of power grids and electrical equipment, the guarantee of product quality, and the normal operation of people's production and life. The use of high-efficiency power load equipment can save a lot of energy and delay the contradiction of power demand, thereby saving a lot of investment required for power construction. Therefore, it has become the common wish of many parties to improve the quality of power supply and meet the needs of production development. From the point of view of power quality, it has become a top priority to study the harmonic reactive power compensation device in depth so that it can meet the act...
