Main transformer vacuum oil is one of operation very crucial in transformer overhaul and capital construction work, and it directly affects the insulating property of transformer.When main transformer vacuum oil, maintainer does not observe the inner real oil level of transformer, can only carry out with the situation of change of injection flow, vacuum meter the Position Approximate of guestimate oiling transformer, often there will be two kinds of situations, the one, oiling oil level is too low, the device body of transformer is not immersed in oil completely, and after releasing vacuum, air enters fuel tank, and moisture enters insulation course to be reduced transformer performance index and has potential safety hazard; The 2nd, oiling oil level is too high, build-up of pressure release action oil spout, and also transformer oil enters vacuum pump and causes unnecessary waste, when serious, can damage vacuum pump.
Summary of the invention
The present invention is used for solving the defect of above-mentioned prior art and provides a kind of simple in structure, and reaching after predetermined altitude can automatic alarm and stop the transformer vacuum oil auto-stopper of oiling.
Problem of the present invention solves by the following technical programs:
A kind of transformer vacuum oil auto-stopper, its special feature is: it comprises support, the first tongue tube, the first floating drum, the second tongue tube, the second floating drum and ring flange, support is fixed on ring flange bottom, the first tongue tube, the second tongue tube are separately fixed on support from high to low, described the first floating drum is positioned at the first tongue tube bottom, hinged with support, the 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, described first, second spar structures is identical, formed by floating drum shank and floating drum body respectively, floating drum body is bucket-shaped, its base angle is arc-shaped transitional surface, described magnetic piece is arranged on the lateral wall place of floating drum body near tongue tube, and described floating drum shank end is provided with counterweight nut.
Above-mentioned transformer vacuum oil auto-stopper, described ring flange bottom is provided with the first binding post, the second binding post, wherein, the first binding post connects the first tongue tube, external oiling power-off loop in wire, and the second binding post connects the second tongue tube, external oiling alarm circuit in wire.
Above-mentioned transformer vacuum oil auto-stopper, described the first floating drum, the second floating drum and vertical direction angle α are 30-45 °.
Above-mentioned transformer vacuum oil auto-stopper, is also provided with two gag lever posts on described support, each gag lever post lays respectively at the hinge rear portion of first, second floating drum.
Above-mentioned transformer vacuum oil auto-stopper, described ring flange bottom is provided with sealing gasket.
The present invention is directed to 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 arranged on transformer open top position, when transformer vacuum oil, can send and reports to the police and stop oiling according to oil level, uses this device can effectively prevent the drawback that causes transformer core body to make moist because oil level is low, is conducive to extend transformer serviceable life; This device can also prevent from running oily phenomenon because of the too high appearance of oil level in the time of oiling, can reduce the loss of transformer oil, prevents oiling device damage.The present invention is simple in structure, use, easy to carry.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the structural representation of floating drum.
In accompanying drawing, the label of each parts is expressed as follows: 1. ring flange; 2. sealing gasket; 3. the first binding post; 4. the first tongue tube; 5. the first floating drum; 6. the second binding post; 7. the second tongue tube; 8. the second floating drum; 9. magnetic piece; 10. support; 11. oiling power-off loops; 12. oiling alarm circuits; 13. gag lever posts; 14. counterweight nuts.
Embodiment
Referring to Fig. 1, Fig. 2, the present invention includes support 10, ring flange 1, for controlling the first tongue tube 4, first floating drum 5 in oiling power-off loop, for controlling the second tongue tube 7, second floating drum 8 of oiling alarm circuit.Support 10 is fixed on ring flange 1 bottom, the first tongue tube 4, the second tongue tube 7 are separately fixed on support from high to low, described the 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, described ring flange 1 bottom is provided with the first binding post 3, the second binding post 6, wherein, the first binding post 3 connects the first tongue tube 4 in wire, external oiling power-off loop 11, the second binding posts 6 connect the second tongue tube 7, external oiling alarm circuit 12 in wire.Oiling alarm circuit 12 and oiling power-off loop 11 (not shown) that is connected with panalarm, power cutoff device respectively.For ensureing sealing, be provided with sealing gasket 2 in ring flange 1 bottom.
Referring to Fig. 3, described the first floating drum 5, the second floating drum 8 structures are identical, and they are made up of floating drum shank and floating drum body respectively, and floating drum body is bucket-shaped, and its base angle is arc-shaped transitional surface, and described magnetic piece 9 is arranged on the lateral wall place of floating drum body near tongue tube.The designed spar structures shape of the present invention both can have been 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 by adjusting the quality of counterweight nut, make two floating drums is 30-45 ° with vertical direction angle α under the state of nature of not floating.Spar design of the present invention is lever, and selects suitable state of nature angle, than direct-lifting floating drum, is active in one's movements and is not easy to be stuck, and the latter is easily broken down.And, if the excesssive gap between floating drum and guiding parts can affect the action sensitivity of tongue tube, if gap is too small, although sensitivity fluctuation diminishes, is easily subject to ectocine and occurs stuck fault.
