Description
Technical field
The utility model belongs to oiling transformer technical field, and in particular to a kind of oiling transformer auto-stopper.
Background technology
Main transformer oiling is one of process very crucial in transformer overhaul and capital construction work, and it directly affects transformer
Insulating properties.During oiling transformer, maintainer does not observe the real oil level of inside transformer, can only be with injection flow, vacuum
The situation of change of meter carrys out the Position Approximate of rough estimate oiling transformer, and often there will be two kinds of situations, first, oiling oil level mistake
Low, the device body of transformer is not completely immersed in oil, and air enters fuel tank, and moisture enters insulating barrier reduction transformer performance and referred to
Mark and potential safety hazard be present；Second, oiling oil level is too high, the action oil spout of build-up of pressure release, unnecessary waste is caused.
Utility model content
The purpose of this utility model is to provide a kind of oiling transformer auto-stopper, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical scheme：A kind of oiling transformer auto-stopper,
Including transformer shell and fuel tank, the outer wall upper end of the transformer shell is provided with check valve, and the direction of the check valve is pointed to
Inside transformer shell, connected between the check valve and fuel tank by oil pipe, the oil pipe is provided with oil pump, the transformer
The top of housing is connected with conservator by pipeline, and the side of the transformer shell connects pipe, the company by connecting tube
Adapter is provided with two and connects the top and bottom of pipe respectively, and the sidewall upper of the communicating pipe switchs provided with feed liquor, institute
State feed liquor switch left and right inwall between be provided with cushion, the lower surface of the cushion is provided with contact block, the cushion
Lower section be provided with it is fixed pad, the right side of the feed liquor switch is provided with two electrodes, and the electrode is respectively with contact block and fixing pad
It is electrically connected with, is provided with inlet among the left surface of the feed liquor switch, the electrode is electrically connected with oil pump.
Preferably, the surface of the contact block is provided with anti-corrosion layer.
Preferably, the periphery of the communicating pipe is provided with the protecting crust for being used for preventing that communicating pipe from damaging.
Technique effect of the present utility model and advantage：The oiling transformer auto-stopper, rational in infrastructure, practicality
By force, the setting of feed liquor switch, for the work of control oil pump, the setting of cushion, for the pressure of sensor transformer oil, contact
The setting of block and fixed pad, circuit is connected when both contact, very convenient, the setting of conservator, is prevented in transformer shell body
Hypertonia.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is feed liquor switch structure diagram of the present utility model.
In figure：1 transformer shell, 2 conservators, 3 fuel tanks, 4 oil pipes, 5 check valves, 6 oil pumps, 7 communicating pipes, 8 connecting tubes, 9 are entered
Pad, 14 electrodes, 15 inlets are fixed in liquid switch, 10 protecting crusts, 11 cushions, 12 contact blocks, 13.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
The utility model provides a kind of oiling transformer auto-stopper as depicted in figs. 1 and 2, including transformer
Housing 1 and fuel tank 3, the outer wall upper end of the transformer shell 1 are provided with check valve 5, and transformer is pointed in the direction of the check valve 5
Inside housing 1, connected between the check valve 5 and fuel tank 3 by oil pipe 4, the oil pipe 4 is provided with oil pump 6, the transformer
The top of housing 1 is connected with conservator 2 by pipeline, and the side of the transformer shell 1 connects pipe 7, institute by connecting tube 8
Connecting tube 8 is stated provided with two and connects the top and bottom of pipe 7 respectively, the sidewall upper of the communicating pipe 7 is provided with feed liquor
Switch 9, the feed liquor are provided with cushion 11 between switching 9 left and right inwall, and the lower surface of the cushion 11 is provided with contact block
12, the lower section of the cushion 11 is provided with fixed pad 13, and the right side of the feed liquor switch 9 is provided with two electrodes 14, the electricity
Pole 14 is electrically connected with contact block 12 and fixed pad 13 respectively, and inlet 15, institute are provided among the left surface of the feed liquor switch 9
State electrode 14 to be electrically connected with oil pump 6, the surface of the contact block 12 is provided with anti-corrosion layer, and the periphery of the communicating pipe 7 is provided with
For the protecting crust 10 for preventing communicating pipe 7 from damaging.
Operation principle：When the transformer oil in transformer shell 1 tails off, the transformer oil liquid level in communicating pipe 7 also can
Reduce, when liquid level is less than feed liquor switch 9, contact block 12 is contacted with fixed pad 13, and circuit is connected, and oil pump 6 will work, from oil
The oil transportation into transformer shell 1 of case 3, the setting of check valve 5, prevents transformer oil from flowing back, when liquid level is higher than feed liquor switch 9,
