Description
Technical field
This utility model relates to a kind of transformator leakage testing device, belongs to transformer production technical field of measurement and test.
Background technology
The leak test test of transformator concerns the sealing property of transformator, and one of the sealing of transformator important performance indexes that to be transformator can dispatch from the factory safely uses. The equipment of the detection leak test that we commonly use at present and method, it is the air pressure utilizing a valve to be 50Kpa by air compressor machine toward charged pressure in transformer tank body, remaining force value is observed after 24 hours, force value is not less than the 70% of setting, and we are considered as the sealing of transformator and meet industry regulation; Otherwise, then judge that transformator sealing is defective. The gas injection device simply connected by this valve not only in gas injection and aerofluxus in-convenience in use; and usually have gas leak phenomenon and occur, so that it is defective to occur judging when leak test is unsatisfactory for condition that the casing leakage of transformator or the gas leakage of valve connecting device cause. Cause the transformator occasionally resulting in good seal performance also to there will be detection defective, cause the erroneous judgement to conforming product rate, not only have impact on production efficiency, and cause the waste of manpower, financial resources. Prior art is also had gas injection and the problem of aerofluxus inconvenience of being solved by one copper ball valve switching device of increase, but copper ball valve switch is contained on valve, and valve is connected with Pressure gauge etc. by connector, its structure is complex, and the air-tightness of this connection is also good not.
Summary of the invention
The purpose of this utility model is in that, for above-mentioned the deficiencies in the prior art, it is provided that a kind of simple in construction, and overall air-tightness is good, convenient installs and can observe the transformator leakage testing device that pressure shows at any time.
This utility model is to realize above-mentioned purpose by the following technical solutions:
This transformator leakage testing device is made up of three-way pipeline, jointing and seal washer, it is characterized in that: equipped with changeover valve on the above passage of described three-way pipeline, equipped with Pressure gauge on the left-hand channel of three-way pipeline, the right-side channels of three-way pipeline makes and has the screw thread valve being connected with air compressor machine, the lower end of the three-way pipeline pressure testing mouth by jointing connection transformer casing.
Described jointing is connected by nipple with the pressure testing mouth of transformer-cabinet, and junction is equipped with seal washer.
The bottom of described jointing makes spanner bayonet socket.
This utility model having the beneficial effects that compared with prior art:
This transformator leakage testing device adopts three-way pipeline structure, equipped with changeover valve on passage in the above, equipped with the Pressure gauge of display pressure on the passage on the left side, passage on the right makes and has the screw thread valve being connected with air compressor machine, jointing connection transformer casing is passed through in the lower end of three-way pipeline, and attachment structure is simple, passes through changeover valve, can the precision of Control experiment pressure requirements, and air pressure can be injected easily and discharge gas. It addition, screw thread valve is one-body molded with three-way pipeline, decrease connecting link, good volume ensure that the air-tightness of leakage testing device itself, greatly improve the accuracy of seal tightness test, it is to avoid prior art easily occurs the phenomenon of erroneous judgement, thus improve production efficiency.

Detailed description of the invention
This transformator leakage testing device is made up of three-way pipeline 1, jointing 5 and seal washer 7, equipped with changeover valve 2 on the above passage of described three-way pipeline 1, equipped with Pressure gauge 4 on the left-hand channel of three-way pipeline 1, the right-side channels of three-way pipeline 1 makes and has the screw thread valve 3 being connected with air compressor machine, the lower end of the three-way pipeline 1 pressure testing mouth by jointing 5 connection transformer casing. Described jointing 5 is connected by nipple 8 with the pressure testing mouth of transformer-cabinet, and junction is equipped with seal washer 7, and the bottom of jointing 5 makes spanner bayonet socket 6. (referring to accompanying drawing).
The work process of this transformator leakage testing device is, the pressure testing mouth of the nipple 8 of jointing 5 bottom with transformer-cabinet is threaded connection, and tightened by spanner bayonet socket 6 with spanner, the bottom of jointing 5, equipped with seal washer 7, can ensure that junction will not leak gas. Again the valve of air compressor machine is connected with screw thread valve 3 by nut, opens changeover valve 2, can be inflated in transformer tank body; During inflation, observe the blowing pressure in transformer tank body by Pressure gauge 4, when the blowing pressure reaches setting, close changeover valve 2 and take off the trachea of air compressor machine, by the Pressure gauge 4 i.e. change of observable transformer-cabinet internal gas pressure value.
The above is preferred embodiment of the present utility model, the example above illustrates flesh and blood of the present utility model is not done any pro forma restriction, any simple modification that above detailed description of the invention has been made according to technical spirit of the present utility model by person of an ordinary skill in the technical field after having read this specification or deformation, and the technology contents possibly also with the disclosure above is changed or is modified to the Equivalent embodiments of equivalent variations, all still fall within the scope of technical solutions of the utility model, without departing from spirit and scope of the present utility model.
