[0002] In power production, protection devices are installed in switchgears. Good heat dissipation of the devices is a prerequisite for ensuring the safe and stable operation of the protection devices.

[0003] At present, in actual on-site work, the heat dissipation of the devices only relies on air cooling. Some devices have densely arranged openings on the outer shell to enhance heat dissipation; air conditioners are installed in the protection cubicles to enhance the heat dissipation effect and assist the stable operation of the devices. Existing protection devices are generally plug-in type, and there are a large number of empty plug positions inside, which provides a basis for the use of this patent.

[0004] The current method has the following defects and deficiencies:

[0005] (1) The air in the switchgear is not circulating, and the heat dissipation efficiency is very low only through air cooling;

[0006] (2) The empty plug positions are not utilized, resulting in low heat dissipation efficiency.

[0007] In view of the above defects and deficiencies, it is urgent to design a cooling device for protecting switchgear equipment, which can be used for the heat dissipation of protection devices. Content of the Utility Model

[0008] The utility model provides a cooling device for protecting switchgear equipment, aiming to solve the problems of low cooling efficiency of air cooling and non-utilization of empty plug positions in the prior art.
