Abstract
The present invention relates to a transformer leakage testing device, belonging to the field of the transformer production testing technology. The transformer leakage testing device comprises a tee-junction pipeline, an attachment joint and a sealing washer; a rotary valve is arranged at the upper channel of the tee-junction pipeline; a pressure gage is installed at the left channel of the tee-junction pipeline, and a thread air gap connected with an air compressor is arranged at the right channel of the tee-junction pipeline; and the lower end of the tee-junction pipeline is connected with the pressure testing port of a transformer box through the attachment joint. The transformer leakage testing device is simple in connection structure and good in sealing performance, is able to accurately control the testing pressure, and is easy to inject air pressure and exhaust gases by connecting a tee-junction pipeline structure with a rotary valve, a pressure gage and a thread air gap. Besides, the thread air gap and the tee-junction pipeline are integrated to form a one-body structure, so that the connection links are decreased, the airtight of the leakage testing device itself is ensured, the accuracy of the sealing test is greatly improved, and phenomenon is avoided that erroneous judgements are easy to occur in the prior art, therefore the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of transformer leakage testing device, belong to transformer production technical field of measurement and test.
Background technology
The leak test test of transformer concerns the sealing property of transformer, and one of the sealing of transformer important performance indexes that to be transformer can dispatch from the factory safely uses.Our equipment of detection leak test commonly used and method at present, utilize the air pressure that a valve is 50Kpa by air compressor machine toward charged pressure in transformer-cabinet, remaining force value is observed after 24 hours, force value is not less than 70% of setting, and we just think that the sealing of transformer meets industry regulation; Otherwise, then judge that transformer sealing is defective.The gas injection device simply connected by this valve not only uses inconvenient in gas injection and exhaust; and usually have gas leak phenomenon occur so that cannot judge when occurring that leak test does not satisfy condition transformer casing leak or valve coupling arrangement gas leakage cause defective.Cause sometimes cause the transformer of good seal performance also there will be detect defective, cause the erroneous judgement to product percent of pass, not only have impact on production efficiency, and cause the waste of manpower, financial resources.Also the problem solving gas injection and exhaust inconvenience by increasing a copper ball valve switchgear is had in prior art, but copper ball valve switch is contained on valve, and valve is connected with tensimeter etc. by web member, its structure is comparatively complicated, and the impermeability of this connection is also good not.
Summary of the invention
The object of the invention is to, for above-mentioned the deficiencies in the prior art, provide a kind of structure simple, overall impermeability well, is conveniently installed and can be observed the transformer leakage testing device of pressure display at any time.
The present invention realizes above-mentioned purpose by the following technical solutions:
This transformer leakage testing device is made up of three-way pipeline, jointing and packing washer, it is characterized in that: the passage above of described three-way pipeline is equipped with changeover valve, the left-hand channel of three-way pipeline is equipped with tensimeter, the right-side channels of three-way pipeline is manufactured with the screw thread valve be connected with air compressor machine, the pressure testing mouth of jointing connection transformer casing is passed through in the lower end of three-way pipeline.
Described jointing is connected by threaded connector with the pressure testing mouth of transformer-cabinet, and packing washer is equipped with in junction.
The bottom of described jointing is manufactured with spanner bayonet socket.
The present invention's beneficial effect is compared with prior art:
This transformer leakage testing device adopts three-way pipeline structure, passage is in the above equipped with changeover valve, the tensimeter of display pressure the passage of on the left side is equipped with, passage is on the right manufactured with the screw thread valve be connected with air compressor machine, the lower end of three-way pipeline is by jointing connection transformer casing, and syndeton is simple, passes through changeover valve, can the precision of Control experiment pressure requirements, and air pressure and Exhaust Gas can be injected easily.In addition, screw thread valve and three-way pipeline one-body molded, decrease connecting link, good volume ensure that the impermeability of leakage testing device itself, greatly improve the accuracy of impermeability test, avoid the phenomenon easily occurring erroneous judgement in prior art, thus improve production efficiency.
