Said method can reduce energy consumption, improve the fail safe that ash removal efficiency improves dedusting simultaneously, switch cubicle can complete cleaning works without the need to power-off, using purification words as dust-collecting air, the impurity particle in air can be avoided, affect its dust removing effects, avoid the charged particle in air simultaneously, affect the insulating properties in cabinet, reach good dust removal efficiency.
To sum up, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, structure is simple, easy to use, is convenient to promote, and can be adapted to each cabinet inner-cavity structure of all kinds switch cubicle, have good dust removing effects.
2, the control system of its dedusting mechanism, rationally, good teamwork, unifiedly controls in collocation, can dedusting, injection, purification, exhaust work unify cooperation and complete.
3, its purification method can provide the air being more suitable for dedusting, and boosting method and injection method can provide and make dust-collecting air form air stream, have better dust removing effects, the dust be adsorbed on parts can be removed.
4, this dedusting mechanism is applicable to the band electric precipitation work of switch cubicle, the on-off times because of dedusting reason can be reduced, thus improve the useful life of switch cubicle, prevent dust accretions from cabinet, making switch cubicle insulating properties reduce, or the situation that the normal work of components and parts is affected occur.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
