Description
Technical field
The utility model provides a kind of automatic reading device for measuring gassing property of transformer oil, belongs to power automation technology of instrument and meter field.
Background technology
The degassing property of transformer oil is a conventional sense project of transformer oil, by the test of this index, can know the degassing property size of tested sample oil under high-voltage electric field, for the safe operation of power transformer provides a reference frame.At present, the instrument that has only a few manufacturer production oil product degassing property test usefulness both at home and abroad, the size of its degassing property is to know that by the scale indication of reading on the eudiometer tube there is certain defective in such test: the one, need manually read scale value, and the 2nd, the data accuracy of reading is not high.Owing to be manually to read calibration data, the tester must be on duty on the instrument next door, very time-consuming, effort.
The utility model content
The automatic reading device that the measuring gassing property of transformer oil that the purpose of this utility model provides a kind ofly can overcome above-mentioned defective, read gas volume that measuring gassing property produces automatically, improve measuring accuracy and efficient is used.Its technology contents is:
Comprise linear electric motors, temperature sensor, be marked with U type eudiometer tube, gassing electrode and the computing machine of dioctyl phthalate dibutylester, wherein linear electric motors are lifted on the back up pad, the control end of computing machine connects linear electric motors and gassing electrode respectively, U type eudiometer tube places in 80 ℃ of constant temperature enclosures, it is characterized in that: the left support arm level bending of U type eudiometer tube, be connected with the gassing electrode, the right support arm of U type eudiometer tube vertically upward, temperature sensor is arranged on the screw mandrel bottom of linear electric motors, the mouth of pipe of the right support arm of U type eudiometer tube is undertaken on the below of screw mandrel, and is positioned on the same vertical line with screw mandrel.
Described automatic reading device for measuring gassing property of transformer oil, temperature sensor are positioned at the mouth of pipe center of the right support arm of U type eudiometer tube in vertical direction.
Described automatic reading device for measuring gassing property of transformer oil, temperature sensor under the drive of screw mandrel, can be in the right support arm of U type eudiometer tube vertical moving up and down.
Described automatic reading device for measuring gassing property of transformer oil, the dioctyl phthalate dibutylester is positioned at the bottom of U type eudiometer tube.
Its principle of work is: under the normality, the dioctyl phthalate dibutylester of U type eudiometer tube inner bottom part about U type eudiometer tube in two support arms liquid level maintain an equal level, the screw mandrel of computer control linear electric motors is descending, when temperature sensor 4 records tangible temperature variation, show the liquid level that has arrived the dioctyl phthalate dibutylester, computing machine writes down the operation of screw mandrel at once.During test, the H2 that is emitted by the gassing electrode enters U type eudiometer tube from the left support arm of U type eudiometer tube bending, the liquid level of dioctyl phthalate dibutylester in the right support arm of U type eudiometer tube is raise, the screw mandrel that computing machine is controlled linear electric motors once more moves down, when temperature sensor measures tangible temperature variation once more, computer recording this moment screw mandrel range ability, by the difference of twice range ability that is write down and the internal diameter of eudiometer tube, but quantitative Analysis goes out the degassing property of gassing electrode-be the size of gassing gas volume.
The utility model compared with prior art can be realized the gassing property of transformer oil analysis robotization completely improving accuracy of test and testing efficiency greatly, and the laboratory technician is freed from loaded down with trivial details test.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, back up pad 2, linear electric motors 3, screw mandrel 4, temperature sensor 5, U type eudiometer tube 6, dioctyl phthalate dibutylester 7, computing machine 8, gassing electrode 9, constant temperature enclosure
Embodiment
Linear electric motors 2 are lifted on the back up pad 1, the control end of computing machine 7 connects linear electric motors 2 and gassing electrode 8 respectively, U type eudiometer tube 5 places in 80 ℃ of constant temperature enclosures 9, left side support arm level bending, be connected with gassing electrode 9, right support arm vertically upward, be marked with dioctyl phthalate dibutylester 6 in the U type eudiometer tube 5, temperature sensor 4 is arranged on screw mandrel 3 bottoms of linear electric motors 2, the mouth of pipe of U type eudiometer tube 5 right support arms is undertaken on the below of screw mandrel 3, and be positioned on the same vertical line with screw mandrel 3, temperature sensor 4 under the drive of screw mandrel 3, can be in the right support arm of U type eudiometer tube 5 vertical moving up and down.
During test, earlier U type eudiometer tube 5 is carried out 80 ℃ of constant temperature.Under the normality, the dioctyl phthalate dibutylester 6 of U type eudiometer tube 5 inner bottom parts about U type eudiometer tube 5 in two support arms liquid level maintain an equal level, the screw mandrel 3 of computing machine 7 control linear electric motors 2 is descending, when temperature sensor 4 records tangible temperature variation, show the liquid level that has arrived dioctyl phthalate dibutylester 6, the stroke of computing machine 7 record screw mandrels 3 moves on beginning then, gets back to initial position.During test, the H2 that is emitted by gassing electrode 8 enters U type eudiometer tube 5 from the left support arm of U type eudiometer tube 5 bendings, the liquid level of dioctyl phthalate dibutylester 6 in the U type eudiometer tube 5 right support arms is raise, computing machine 7 is controlled screw mandrel 3 once more and is moved down, when temperature sensor 4 measures tangible temperature variation once more, the range ability of computing machine 7 record screw mandrels 3 this moment, by the difference of twice range ability of record and the internal diameter of U type eudiometer tube 5, but quantitative Analysis goes out the degassing property of gassing electrode 8-be the size of gassing gas volume.
