Be described further below in conjunction with the airtight cooling air channel of power cabinet of accompanying drawing to a kind of static reacance generator of the utility model.
Accompanying drawing explanation
Fig. 1 is the front view of the airtight cooling air channel of power cabinet of a kind of static reacance generator of the utility model.
Embodiment
As shown in Figure 1, be the front view of the airtight cooling air channel of power cabinet of a kind of static reacance generator of the utility model, comprise centrifugal blower 2, first air channel 3 and the second air channel 5.Multiple power model 4 is installed side by side in the power cabinet inside of static reacance generator, each power model 4 inside is provided with air duct, in air duct inside, radiator is installed, one end of air duct is provided with out sealing gland mouth, the other end is provided with air inlet envelope mouth, in air inlet envelope, mouth place is provided with screen pack, and dust ingoing power module 4 can be prevented inner.The lower end in the second air channel 5 is provided with air inlet 6, air inlet 6 is communicated with outdoor by pipeline, sidewall along the second air channel 5 offers multiple second connector side by side, second connector seals mouth with the air inlet of air duct respectively and is connected, junction is provided with dismountable insulation board, is convenient to clear up the dust at air inlet envelope mouth place.The top in the first air channel 3 is provided with gas outlet 1, gas outlet 1 place is provided with centrifugal blower 2, gas outlet 1 is connected with outdoor by pipeline, sidewall along the first air channel 3 offers multiple first connector side by side, first connector is connected with the sealing gland mouth that goes out of air duct respectively, junction is provided with dismountable insulation board, and the dust be convenient to going out sealing gland mouth place is cleared up.First air channel 3 is identical with the volume size of the second air channel 5 internal cavity, is convenient to keep blast constant.
