[0002] The common box bus is a primary equipment commonly used in current power plants, is often used for connecting between the standby transformer of starting, the plant transformer and 10kV / 6kV switch cabinet etc. Due to the influence of the geographical environment of certain regions, the condensation of different degrees often appears in the inside of the common box bus after a period of operation when overhauling for those common box buses installed in the place of relatively humid and large diurnal temperature range, and these condensation can seriously affect the safe operation of the common box bus, and even more seriously can cause the unit tripping. Although the existing technology has some dehumidification mechanisms installed in the common box bus, can play a certain dehumidification and drying effect, but due to its installation in the inside of the common box bus, causes very inconvenient maintenance or replacement, is not easy to operate.

[0003] The heating cable control scheme commonly used at present can only heat the air in the inside of the common box bus, and has no obvious effect on dehumidification. Due to the deformation of the box cover plate, the aging of the sealing strip, the deterioration of the busbar insulation support material, the aging of the heating band leading to insufficient heating capacity and other reasons, the insulation is seriously decreased due to the condensation of the busbar in rainy weather.

It can not only use the condenser to achieve internal circulation dehumidification inside the common busbar, but also use the fan to draw in outside air for dehumidification and heat dissipation inside the common busbar. It is suitable for use when dehumidifying inside the common busbar. This solution is effective, easy to install, has comprehensive functions, a high degree of intelligence, and is flexible and economical. Attached Figure Description
