There is fly net；The air inlet is connected universal driving shaft with air outlet blind window hinge, and universal driving shaft is through travelling gear and power transmission shaft phase
Even, power transmission shaft one end is connected with exchange stepper motor, and by exchange driving stepper motor, temperature sensor is placed in transformer room,
Be responsible for collection transformer real time temperature, temperature sensor is connected with single-chip microcomputer temperature control processor, single-chip microcomputer temperature control processor and
Exchange stepper motor is connected, and controls the folding of blind window.
Exhaust blower is provided with the inside of air outlet fly net, the start and stop of exhaust blower are controlled by temperature control processor.
The air inlet is located at transformer room's back underside, and air outlet is located at transformer room front upside.
The single-chip microcomputer temperature control processor is externally provided with manual control panel, manually controls folding and the exhaust blower of blind window
Start and stop.
The beneficial effects of the utility model：The utility model uses said structure, overcome using casing gravity-flow ventilation without
The problems such as service life caused by method meets cooling requirements, simple setting exhaust blower is relatively low, increase repair and maintenance workload, passes through
The exhaust blower of retractable blind window, controllable rotating speed is set, blower fan and blind window are closed when temperature is not exceeded, prevents dirt worm from entering
Enter, do not reduce the degree of protection of case change, open during temperature exceeding standard, realization is radiated on demand, so as to improve the power supply of box-type substation
Reliability.

Embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
A kind of controllable ventilated cooling type box-type substation, its structure are：Box for box-type transformer substation 1 is by hyperbaric chamber 2, transformer
4 three room 3, low-pressure chamber separate space compositions, wherein setting air inlet 6 and air outlet 5 in transformer room, air port uses hundred
The page form of window 12, the inner side of blind window 12 are provided with fly net 13.
According to cold-hot air convection principle, the air inlet 6 is located at the back underside of transformer room 3, and air outlet 5 is located at transformation
