Background technology
During voltage levels high-power transformer is transported or preserved, to avoid transformer body from making moist, it is necessary to be filled
Gas shielded.Prior art generally carries out damp-proof treatment, but high-power transformer sheet by the way of nitrogen is filled to transformer body
Body keeping, installation, haul-cycle time are longer, the phenomenon often to leak air, if not finding and adopting remedial measures in time, easily lead
Cause transformer body to make moist, influence subsequently to use.It is therefore desirable to monitor transformer air pressure change in time and take counter-measure.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of oil-free transformer automatic air supply device, is become with improving
The preservation effect of depressor body, keeps away from moisture.
In order to achieve the above object, the utility model provides following technical scheme：
Oil-free transformer automatic air supply device, including transformer body, liquid nitrogen storage tank and switch board, the liquid nitrogen storage tank and
Switch board is arranged on the side wall of transformer body, in addition to transformer pressure sensor, gas pipeline and transformer air inlet, institute
State, liquid nitrogen storage tank, switch board and transformer air inlet are sequentially connected in series by gas pipeline, the transformer pressure sensor and control
Cabinet electrical connection processed.
Further, control unit, buffer, electromagnetic switch I K1, pressure-reducing valve, the liquid nitrogen are provided with inside the switch board
Storage tank, buffer, electromagnetic switch I K1, pressure-reducing valve and transformer air inlet are concatenated by gas pipeline, described control unit with
Electromagnetic switch I K1 are electrically connected.
Further, in addition to electromagnetic switch III K3, described control unit electrically connect with electromagnetic switch III K3.
Further, in addition to triple valve, the liquid nitrogen storage tank number is two, each liquid nitrogen storage tank outlet respectively with triple valve
Entrance be connected, the triple valve is connected with transformer air inlet.
Oil-free transformer automatic air supply device of the present utility model can monitor the change of transformer body air pressure inside at any time
Change, tonifying Qi at any time, avoids transformer from making moist as needed.
