Background technology
The main transformer vacuum oil is one of operation very crucial in transformer overhaul and the capital construction work, and it directly influences the insulating property of transformer.During the main transformer vacuum oil; The maintainer does not observe the inner real oil level of transformer, can only come the Position Approximate of guestimate oiling transformer with the situation of change of injection flow, vacuum meter, tends to occur two kinds of situation; The one, the oiling oil level is low excessively; The device body of transformer is not immersed in the oil fully, and air gets into fuel tank after the releasing vacuum, and moisture gets into insulation course to be reduced the transformer performance index and have potential safety hazard; The 2nd, the oiling oil level is too high, build-up of pressure release action oil spout, and also transformer oil gets into vacuum pump and causes unnecessary waste, can damage vacuum pump when serious.
Summary of the invention
The present invention is used to solve the defective of above-mentioned prior art and provides a kind of simple in structure, reaches the transformer vacuum oil auto-stopper that can report to the police and stop oiling behind the predetermined altitude automatically.
Problem according to the invention solves through following technical scheme:
A kind of transformer vacuum oil auto-stopper; Its special feature is: it comprises support, first tongue tube, first floating drum, second tongue tube, second floating drum and ring flange; Support is fixed on the ring flange bottom, and first tongue tube, second tongue tube are separately fixed on the support from high to low, and said first floating drum is positioned at the first tongue tube bottom, hinged with support; Second floating drum is positioned at the second tongue tube bottom, hinged with support, and first, second floating drum is provided with magnetic piece.
Above-mentioned transformer vacuum oil auto-stopper; Said first, second spar structures is identical; Be made up of floating drum shank and floating drum body respectively, the floating drum body is bucket-shaped, and its base angle is the arc transition face; Said magnetic piece is arranged on the lateral wall place of floating drum body near tongue tube, and said floating drum shank end is provided with the counterweight nut.
Above-mentioned transformer vacuum oil auto-stopper; Said ring flange bottom is provided with first binding post, second binding post; Wherein, first binding post connects first tongue tube, external oiling outage loop in lead, and second binding post connects second tongue tube, external oiling alarm circuit in lead.
Above-mentioned transformer vacuum oil auto-stopper, said first floating drum, second floating drum and vertical direction angle are 30-45 °.
Above-mentioned transformer vacuum oil auto-stopper also is provided with two gag lever posts on the said support, each gag lever post lays respectively at the hinge rear portion of first, second floating drum.
Above-mentioned transformer vacuum oil auto-stopper, said ring flange bottom is provided with sealing gasket.
The present invention is directed to the main transformer vacuum oil, the uppity problem of oil level height is improved, and has designed a kind of transformer vacuum oil auto-stopper.This device is installed in transformer open top position, during transformer vacuum oil, can send according to oil level and report to the police and stop oiling, uses this device can effectively prevent because of the low drawback that causes the transformer core body to make moist of oil level, helps prolonging transformer serviceable life; This device can also prevent when oiling, to run oily phenomenon because of the too high appearance of oil level, can reduce the loss of transformer oil, prevents the oiling device damage.The present invention is simple in structure, use, easy to carry.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation of floating drum.
The label of each parts is represented as follows in the accompanying drawing: 1. ring flange; 2. sealing gasket; 3. first binding post; 4. first tongue tube; 5. first floating drum; 6. second binding post; 7. second tongue tube; 8. second floating drum; 9. magnetic piece; 10. support; 11. oiling outage loop; 12. oiling alarm circuit; 13. gag lever post; 14. counterweight nut.
Embodiment
Referring to Fig. 1, Fig. 2, the present invention includes support 10, ring flange 1, be used to control first tongue tube 4, first floating drum 5 in oiling outage loop, be used to control second tongue tube 7, second floating drum 8 of oiling alarm circuit.Support 10 is fixed on ring flange 1 bottom; First tongue tube 4, second tongue tube 7 are separately fixed on the support from high to low; Said first floating drum 5 is positioned at the first tongue tube bottom, hinged with support; The second floating drum position 8 in the second tongue tube bottom, with support hinged, first, second floating drum is provided with magnetic piece 9.
Still referring to Fig. 1, Fig. 2; Said ring flange 1 bottom is provided with first binding post 3, second binding post 6; Wherein, first binding post 3 connects first tongue tube 4, external oiling outage loop 11, the second binding posts 6 and in lead, connects second tongue tube 7, external oiling alarm circuit 12 in lead.Oiling alarm circuit 12 and oiling outage loop 11 (not shown) that links to each other with panalarm, power cutoff device respectively.For guaranteeing sealing, be provided with sealing gasket 2 in ring flange 1 bottom.
Referring to Fig. 3, said first floating drum 5, second floating drum, 8 structures are identical, and they are made up of floating drum shank and floating drum body respectively, and the floating drum body is bucket-shaped, and its base angle is the arc transition face, and said magnetic piece 9 is arranged on the lateral wall place of floating drum body near tongue tube.The spar structures shape that the present invention designed both can be born certain pressure under vacuum state, can go up and action flexibly with oil level again.Be provided with counterweight nut 14 at floating drum shank end, can be through the quality of adjustment counterweight nut, making two floating drums is 30-45 ° with the vertical direction angle under the state of nature of not floating.Spar design of the present invention is a lever, and selects suitable state of nature angle, than direct lift floating drum, is active in one's movements and is not easy to be stuck, and the latter is then broken down easily.And, if the excesssive gap between floating drum and the guiding parts, can influence the action sensitivity of tongue tube, if the gap is too small,, receives ectocine easily and stuck fault occurs though sensitivity fluctuation diminishes.
