Abstract
The utility model relates to an oily formula current transformer sealing performance's verifying attachment, characterized in that: including the ring flange, manometer installation cover and valve installation cover be equipped with on the ring flange admittedly, manometer installation cover is built -in to have the manometer that is used for measuring current mutual -inductor internal pressure value, is equipped with the valve in the valve installation cover, and the other end of valve is connected the oil feed and is connected, and it has the exhaust elbow connecting hole to make between the installation is overlapped with the valve at ring flange upward pressure table installation cover, and the rigid coupling is located to the blast pipe connecting hole has the exhaust elbow. The advantage is: the sealing performance that current transformer can be inspectd to the mode of pressing through buying oil can get rid of surplus air wherein again, can also simulate the transformer oil situation of current transformer when the operation and hunt leak, safe, reliable when having guaranteed to suppress the operation.
Description
Technical field
The utility model belongs to current transformer manufacturing technology field, particularly relates to a kind of oil-immersed current transformer closeThe verifying attachment of sealing property.
Background technology
At present, widely used outdoor oil immersion type mutual-inductor, is mainly used in distribution transformer high side voltage and electric current and surveysA kind of metering device of amount and electric energy metrical. Oil immersion type mutual-inductor is made up of parts such as fuel tank, insulator, oil conservater, expanders,Fuel tank adopts metal material to make, and transformer is contained in fuel tank, and in fuel tank, fills transformer oil as insulation, and each partsBetween conventionally to place O-ring seal and securing member fastening. Because hermetically-sealed construction is unreasonable, as sealing surface injustice, O-ring seal compressionAmount is not controlled, or encapsulant is not good enough, the reasons such as sand holes appear in fuel tank welding, causes oil immersion type mutual-inductor to exist sealing propertyThe drawback of bad, leakage of oil, therefore needs the transformer to assembling to carry out the reliable test of sealing property. If sealing propertyTest does not reach relevant mark and regulation, probably can cause product to occur leakage of oil in the time of operation, and then can cause peaceRow hidden danger for the national games.
Summary of the invention
The utility model provides one can effectively improve sealing property for solving the technical problem existing in known technologyTest effect, prevent that transformer is at when operation leakage of oil and the inspection of the reliable oil-immersed current transformer sealing property of handling safetyExperiment device.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
The verifying attachment of oil-immersed current transformer sealing property, is characterized in that: comprise ring flange, on described ring flangeBe fixed with Pressure gauge installation sleeve and valve installation cover, in-built being useful on of described Pressure gauge installation sleeve detected the inner pressure of current transformerThe Pressure gauge of power value, is equipped with valve in described valve installation cover, and the other end of described valve connects fuel inlet fitting, on ring flangeBetween Pressure gauge installation sleeve and valve installation cover, be shaped with exhaust elbow connecting hole, it is curved that described blast pipe connection hole is connected with exhaustPipe.
The utility model can also adopt following technical scheme:
On the circumference of described ring flange, be evenly distributed with 4 for connecting the installing hole of bottom plate for expander.
The gas outlet of described exhaust elbow is arranged on the leading flank of verifying attachment.
On described exhaust elbow, drain tap is housed.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, pass throughThe mode of the pressure of buying oil not only can be checked the sealing property of current transformer, also can be by getting rid of to the mode of current transformer oilingSurplus air wherein, ensures that its inside is full of transformer oil, is convenient to improve transformer oil performance; The force value of interiors of products canBy the pressure gauge reading on this device, convenient, directly perceived; Because the characteristic of oil good fluidity in the time that temperature is high, utilizes this deviceCan inject the transformer oil with uniform temperature, the transformer oil situation during with this dry run to current transformer; This dressThe exhaust elbow of putting design can be got rid of in surplus air and product decompression when pressure is excessive in the time of oiling, has ensured to suppress operationTime safe, reliable.

Detailed description of the invention
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples, and coordinateAccompanying drawing is described in detail as follows:
Refer to Fig. 1-Fig. 7, the verifying attachment of oil-immersed current transformer sealing property, comprises ring flange 5, described flangeOn dish, be fixed with Pressure gauge installation sleeve 4 and valve installation cover 3, the in-built detection current transformer that is useful on of described Pressure gauge installation sleeveThe Pressure gauge of internal pressure value, is equipped with valve 2 in described valve installation cover, and the other end of described valve connects fuel inlet fitting 1,The end opening of fuel inlet fitting is provided with valve. Between ring flange pressure gauge installation sleeve and valve installation cover, being shaped with exhaust elbow connectsHole, described blast pipe connection hole is connected with exhaust elbow 6.
In the present embodiment, described valve 2 adopts ball valve.
In the present embodiment, on the circumference of described ring flange, be evenly distributed with 4 for connecting the installing hole of bottom plate for expander5-1。
In the present embodiment, the gas outlet of described exhaust elbow is arranged on the leading flank of verifying attachment, gives vent to anger to ensureOutwards exhaust of mouth.
In the present embodiment, on described exhaust elbow, drain tap is housed.
Operation principle of the present utility model is:
After vacuum oil, pull down priming cup, this device is connected with bottom plate for expander. Open the valve of exhaust elbow and enterThe valve of oil joint end opening, and from the slow oiling of fuel inlet fitting, until the whole Bas Dischargeds in transformer. Exhaust elbow rowWhen fuel-displaced, close the valve of exhaust elbow, observe manometric reading, in the time that pressure reaches setting, close fuel inlet fitting end openingValve. Now, in transformer, be all full of oil, and reach the force value of regulation. Continue for some time as requested, then observeTransformer has or not leakage of oil, pressure gauge reading to have or not decline can complete inspection.
The embodiment that the utility model accompanying drawing is described is exemplary, only for explaining the utility model, and can not understandFor to restriction of the present utility model.
