Description

Transformer oil level measuring arrangement
Technical field
The present invention relates to a kind of power supply unit service kit, particularly a kind of transformer oil level measuring arrangement.
Background technology
At present, the 66kV and the transformer oil storage of above run in power system for accomplish insulating oil with it is big Thoroughly isolation does not all have observation window to gas, does not possess the condition of the observation true oil level of transformer directly perceived.Daily judgement transformer oil level It is what is realized by observing the oil level gauge on transformer oil storage.The operation principle of oil level gauge is using mechanical linkage connection oil storage Cabinet barrier film or ball float, the interior permanent magnet gap induction band moving teeth wheel drive indicator that passes through of table indicate oil level.The shortcomings that meter, refers to Show that deviation is larger.In addition, during transformer station high-voltage side bus, its transformer oil volume can frequently change with the change of device body temperature, Barrier film in oil conservater（Air bag）Fold can occur with the change of fuel head, so as to produce interference to oil level gauge connecting rod, Cause oil level to indicate distortion, send out alarm signal by mistake, or when actual oil level is abnormal, and oil level gauge can not be indicated normally.
Transformer oil level measuring method of the prior art also has based on thermal imaging method and ultrasonic locatization, but the two has Deficiency：Thermal imaging method is measured with thermal imaging system, and this method measurement accuracy is poor, not intuitively, especially measurement error in the winter time It is bigger；Ultrasonic locatization is measured with ultrasonic tesint instrument, and this method measurement is more accurate, but the instrument involves great expense, cost It is higher, and be easily damaged, not easy care, once concussion of colliding with, will influence measurement accuracy.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of simply and intuitively transformer oil level to measure Device.
The present invention technical solution be：A kind of transformer oil level measuring arrangement, it is characterised in that it is indicated by oil level Pipe, oil hose, Oil-filling and drainage valve door joint, magnet are formed, and oil level instruction drift ball is provided with the oil gauge pipe of transparent material, The bottom of oil gauge pipe is connected with oil hose, and the other end of oil hose is connected with Oil-filling and drainage valve door joint；Oil level indicates The top of pipe is provided with suspension bracket, and magnet is provided with suspension bracket.
Oil exit pipe is also communicated with described oil hose, oil extraction valve is provided with oil exit pipe.
Described magnet is controllable magnet, and the controllable magnet is by rope control magnetic switch control magnetic force.
Described Oil-filling and drainage valve door joint specification is engaged with the Oil-filling and drainage valve door or note drain line of transformer oil storage.
Described suspension bracket is connected by joint with more piece insulating bar.
The present invention after it is connected with transformer oil storage, is indicated using the contour principle of linker liquid level by oil level The position of oil level instruction drift ball in pipe, you can be visually observed that the true altitude of oil level in transformer oil storage.The letter of its structure It is single, operate with simplicity.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is use state diagram of the present invention.
Embodiment
As shown in figure 1, the present invention is mainly by oil gauge pipe 5, oil hose 8, Oil-filling and drainage valve door joint 9, the structure of magnet 1 Into.Oil gauge pipe is transparent material, and oil level instruction drift ball 6 is provided with pipe.The bottom of oil gauge pipe connects with oil hose Connect, the other end of oil hose is connected with the note of Oil-filling and drainage valve door joint, Oil-filling and drainage valve door joint specification and transformer oil storage Oil discharging valve or note drain line are engaged.Oil exit pipe 11 is also communicated with oil hose, oil extraction valve 10 is provided with oil exit pipe. The top of oil gauge pipe is provided with suspension bracket 12, and suspension bracket is connected by joint 3 with more piece insulating bar 4.It is provided with suspension bracket Magnet, magnet are controllable magnet, and the controllable magnet controls magnetic force by rope control magnetic switch 2.
As shown in Fig. 2 in use, Oil-filling and drainage valve door joint 9 is connected into transformer oil storage Oil-filling and drainage valve door 14, with more Controllable magnet 1 on suspension bracket is pull-in on transformer oil storage 13 by section operation insulating bar 4, to fixed oil gauge pipe 5.Close The oil extraction valve 10 closed on oil exit pipe 11, transformer oil storage Oil-filling and drainage valve door 14 is opened, at this moment transformer oil will pass through oil transportation Flexible pipe 8 flows into oil gauge pipe 5, and oily liquid level drives the oil level instruction drift levitating of ball 6, now, drift ball 6 position is indicated by oil level Just the physical location of oil level in transformer can intuitively be shown.Transformer pouring oil discharging valve 14 is closed after observation, opens oil extraction Valve 10 passes through transformer oil in the discharger of oil exit pipe 11.Pull rope control magnetic switch 2 to make the controllable loss of excitation of magnet 1, unload whole Covering device, whole measurement process are completed.
