Description

Frequency converter protection device with dustproof cooling function

Technical Field

The utility model relates to a power equipment technical field, in particular to converter protection device with dustproof cooling function.

Background

The frequency converter is a power control device which controls an alternating current motor by applying a frequency conversion technology and a microelectronic technology and changing the frequency of a working power supply of the motor, and is widely applied along with the continuous improvement of the industrial automation degree; but the inside electric component of current large-scale converter is more, and the structure is comparatively simple, is difficult for realizing the function of removing dust, has some dusts to adhere to equipment shell surface after long-time use, and the converter can produce a large amount of heats in the course of the work, because the dust can dispel the heat at the serious influence converter of equipment shell's surface attached to, thermal giving off can not go out the temperature that can lead to inner structure and rise, influence equipment normal work, the radiating effect that leads to equipment reduces.

The electric parts inside large-scale converter are more, can produce a large amount of heats in the course of the work, and these thermal giveouts can lead to inner structure's temperature to rise, influence equipment normal work, and present device is relatively poor to the protection effect of converter.

The invention discloses an invention patent with the publication number of CN202120482711.2 on 7/3/2021 by the Chinese intellectual Property office, which is named as a frequency converter protection device with a dustproof cooling function and comprises a box body, wherein a door plate is rotationally connected to the front surface of the box body, and moving devices are fixedly connected to the front side and the rear side of the left side surface and the rear side surface of the box body respectively and comprise mounting grooves. This converter protection device with dustproof cooling function, drive dust collector downstream through the push rod motor, gear and rack are mutually supported, make the brush roller rotate and sweep the dust on converter body surface simultaneously, then suction that is produced by the fan is with the dust suction, the device has realized the dust removal function to the converter body, the effectual phenomenon that has prevented to rise because the dust adheres to the converter body that can serious influence frequency converter on the surface of frequency converter body and the converter body inner structure temperature that leads to dispels the heat takes place, the normal work of frequency converter body has been guaranteed, the radiating effect of frequency converter body has been improved. The patent has the following defects: 1) the added electric mechanism is complex; 2) if the gear linkage mechanism breaks down, the protection device cannot normally remove dust.

The invention patent with the publication number of CN202020059451.3 is disclosed by the intellectual property office of China in 2020, 1 month and 13 days, and is named as a frequency converter protection device with a dustproof cooling function, and the patent provides a cooling structure and a dust removal structure; the cooling structure mainly comprises: brace table, packing have the circulation tank, a plurality of circulation pipeline, pump machine and a plurality of joint of coolant liquid, the utility model relates to a converter technical field. This technical scheme adopts forced air cooling and water-cooling structure to realize cooling down to the inside converter of safety cover, comes to get rid of the dust on converter surface by last dust removal structure simultaneously, and this technical scheme can be effectual protects the converter, makes the converter work under suitable environment. The patent has the following defects: 1) additional cooling circulation devices are needed; 2) the equipment is too bulky.

The invention patent with the publication number of CN215222887U is disclosed by the intellectual property office of China at 2021, 7 months and 21 days, and is named as 'a fan frequency converter heat dissipation device for a wind driven generator capable of dissipating heat quickly', the patent provides an installation mechanism, and the left side and the right side of the installation mechanism are provided with speed increasing mechanisms; the connecting mechanisms are arranged on the upper side and the lower side of the speed increasing mechanism; the support mechanism is arranged in the mounting mechanism.
