Description
Technical field
This utility model relates to ventilation technical field, particularly relates to a kind of sand-proof type fans silencer.
Background technology
Transformer station i.e. changes the place of voltage.Electric energy in order to power plant is issued is transported to place farther out, it is necessary to
Voltage being raised, becomes high-tension electricity, the most on demand voltage is reduced near user, transformer station is leaned in the work of this buck/boost
Complete.The capital equipment of transformer station is switch and transformator.In order to meet safety and the needs of management, existing transformer station is most
For closing or semi-enclosed space.In order to avoid temperature too high damage electrical equipment causes creepage phenomenon etc. with there was dampness in the air, need
Indoor low temperature to be kept and air are dried.Existing closing or closet that semiclosed transformer station is normal tape window or large-scale cabinet.
Its shortcoming is that room ventilation is smooth, and heat radiation is relatively slow, and the heat that a large amount of electrical equipments distribute can not be got rid of in time, cause indoor or
In-cabinet temperature is too high, causes electrical equipment to damage, and a large amount of hot-air is after running into the relatively low indoor wall of temperature or cabinet wall
There is condensation frosting, cause in indoor or cabinet that there was dampness in the air, easily cause creepage phenomenon, there is potential safety hazard.Therefore typically exist
Ventilation fan all can be installed in transformer station, but in the more place of some sand and dust of the north, common ventilation fan is during ventilation
Outdoor sand and dust also can be brought into indoor, the sand and dust causing indoor are more, affect the service life of electrical equipment.
