Description

A waterproof switch cabinet

technical field

The utility model relates to the field of electric equipment, in particular to a waterproof switch cabinet.

Background technique

At present, with the continuous development of electrical switchgear, the heat dissipation technical requirements for the switchgear are getting higher and higher. During the working project, the control components in the switchgear will emit a large amount of heat. , The temperature rise in the switchgear will cause the failure of the control system, which will not only make the equipment unable to operate normally, but also bring greater safety hazards. The existing heat dissipation device equipped with the switchgear itself is based on the principle of circulating air to the inside of the switchgear for cooling. When the external temperature is high, the heat dissipation of the switchgear is very slow and the heat dissipation is not obvious, so it is difficult to ensure that the control system of normal operation. At the same time, when the switchgear has been in operation for a long time, or due to overloading, the internal components will age, causing the internal heat of the cabinet to increase, and there is a hidden danger of fire.

Although some existing switchgears are simple in structure and have excellent heat dissipation effects, there are still some shortcomings. First, heat dissipation holes are provided on the cabinet body, and external dust will enter the interior of the switchgear through the heat dissipation holes, thereby affecting some parts inside the switchgear. Damage to electronic components. Secondly, many switchgears are placed outdoors. When there is rainy weather and other environments outside, water can easily enter the inside of the switchgear through the cooling holes, resulting in damage to the switchgear and making it unusable.
