Description

Technical Field

[0001] The utility model relates to the technical field of switching switches, in particular to a capacitor fast switching switch. Background Art

[0002] The capacitor switching switch is a device dedicated to switching capacitors in reactive power compensation devices. It uses a current limiting resistor to first connect the circuit to pre-charge the capacitor, thereby reducing the voltage difference between the power supply and the capacitor. Then the main contact short-circuits the current limiting resistor.

[0003] A Chinese patent with publication number (CN205680582U) discloses a capacitor switching switch, a switch body, heat dissipation holes are arranged on both sides of the switch body, a dust screen is arranged inside the switch body for filtering the air entering the switch body from the heat dissipation holes, and a cleaning member is provided on the switch for scraping dust off the dust screen by sliding, which can effectively scrape off the dust adhering to the dust screen, prevent the dust screen on the switch body from being blocked by dust, and avoid the heat generated by the electrical components in the switch body during operation from being unable to be discharged due to the blockage of the dust screen, thereby ensuring that the electrical components in the capacitor switching switch can work normally.

[0004] The defect of the above-mentioned selected technology is that although the dustproof net can filter the dust in the air, the dustproof net has thickness and depth, and what enters the switch body through the heat dissipation holes is not only dust but also lint, which will be mixed together and adhere to the filter net. When the dust is scraped off with a scraper, dust, lint and a mixture of the two will enter the filter holes, which is difficult to clean, and the dust, lint and the mixture of the two will also be scraped into the inside of the switch body, causing more dust to enter the inside of the switch body.

[0005] The purpose of the utility model is to provide a capacitor fast switching switch to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a capacitor fast switching switch, comprising a switch body, heat dissipation holes are symmetrically opened at the upper and lower ends of both sides of the switch body, mounting grooves are opened on both longitudinal sides of the front side of the switch body, a plug-in frame is detachably connected to the inside of the mounting groove, a filter is fixedly connected to the middle of the plug-in frame, a fixing block is fixedly connected to the upper and lower ends of one side of the filter, a brush is fixedly connected to the side of the fixing block away from the switch body, and a guide rail is fixedly connected to the inner wall of the switch body and located on the outside of the plug-in frame.

[0008] As a preferred solution of the utility model, the pressing plate can press the insertion frame after rotating clockwise around the rotating shaft.

[0009] As a preferred solution of the utility model, the guide rail is provided with a flange, and the direction of the flange is inward.

[0010] As a preferred solution of the utility model, the length of the brush is greater than the depth of the heat dissipation hole.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model can conveniently filter the air entering the switch body through the provided plug-in frame, filter screen and guide rail, and when too much dust is adsorbed on the filter screen, the plug-in frame and filter screen can be removed to clean the dust on the filter screen, and at the same time, under the action of the brush, the filter screen can also clean the dust inside the heat dissipation hole during the disassembly process, thereby improving the cleaning efficiency and avoiding incomplete cleaning of the filter screen, which affects the heat dissipation effect of the switch body.

After the insertion frame 4 is pulled out, the dust accumulated on the filter 5 can be cleaned.
