Drawings
The present invention will be further described with reference to the accompanying drawings.
FIG. 1 is a schematic structural view of the present invention;
in the figure, 1 a cylindrical shell, 2 oil cavities, 3 air cavities, 4 corrugated pipes, 5 sealing plates, 6 through holes, 7 pipe seats, 8 cover plates, 9 photoelectric liquid level switches, 10 breathing pipes, 11 oil level gauges, 12 exhaust pipe joints, 13 oil filling and discharging pipes and 14 main oil pipes.
Detailed Description
The attached drawing is a concrete embodiment of the utility model. This embodiment includes drum shell 1, and drum shell 1 comprises oil pocket 2 and air chamber 3, is equipped with bellows 4 in the air chamber 3, and shrouding 5 is installed to the bellows 4 outside, and through-hole 6 has been seted up to shrouding 5 lower part, and the welding has tube socket 7 on the through-hole 6, installs apron 8 on tube socket 7, and photoelectric liquid level switch 9 is installed to apron 8 lower part, and tube socket 7 lower extreme is located below the 4 bottom of bellows. The air chamber 3 is communicated with a breathing tube 10. An oil level gauge 11 is mounted on the closing plate 5. The top of the cylinder shell 1 is connected with an exhaust pipe joint 12. The bottom of the cylinder shell 1 is communicated with an oil injection and discharge pipe 13. The oil chamber 2 is communicated with a main oil pipe 14.
Adopt the utility model discloses an outer oily formula metal transformer ripple that carries out oil leak monitoring stores up oil tank, drum shell 1 forms two independent spaces respectively with bellows 4, and oil pocket 2 and air chamber 3 promptly, two cavity volumes can change volume separately according to bellows 4's flexible to the volume compensation of oil in the realization is to the transformer. The oil cavity 2 is communicated with the transformer through a main oil pipe 14, and the air cavity 3 is communicated with the outside through a breathing pipe 10, so that the full sealing of the transformer is realized. The oil chamber 2 realizes the functions of exhausting air and supplementing oil in the oil chamber 2 through an exhaust pipe joint 12 and an oil injection and drainage pipe 13 respectively. A through hole 6 is formed in the lower part of the sealing plate 5 outside the corrugated pipe 4, so that a pipe seat 7 with a cover plate 8 is welded, and the pipe seat 7 is close to the edge of the lowest part of the corrugated pipe 4 and is used for collecting transformer oil leaked from the oil cavity 2 into the air cavity 3; and a photoelectric liquid level switch 9 is arranged at the lower part of the cover plate 8 and used for sensing whether transformer oil permeates into the tube seat 7 or not, and monitoring whether the corrugated tube 4 leaks or not is realized by utilizing the liquid sensing function of the photoelectric liquid level switch 9. The photoelectric liquid level switch 9 comprises an infrared light-emitting diode and a photoelectric receiver, light emitted by the infrared light-emitting diode is guided into a prism at the top of the sensor, and if no liquid exists, the light emitted by the infrared light-emitting diode is directly reflected back to the photoelectric receiver from the prism; when the liquid dips into the prism, the light is refracted into the liquid, so that no light or only a small amount of light is received back to the light receiver. By sensing this change, the photoelectric receiver can drive the electrical switch of the internal photoelectric liquid level switch 9 to work, thereby starting an external alarm or control circuit. The photoelectric liquid level switch 9 is arranged at the lowest part of the outer sealing plate 5 of the corrugated pipe 4, so that transformer oil permeating into the corrugated pipe 4 can be sensed most quickly.
