Abstract
The utility model discloses an oily formula distribution transformer oil level gaugember pressure testing device, connect and the oil level gaugember seat including box, air cock, the air cock connects and the oil level gaugember seat all is fixed in the box and communicates with each other with the box inner chamber, the utility model discloses an oily formula distribution transformer oil level gaugember pressure testing device can detect pressure relief valve and whether have the defect, has solved the defect that original nothing detected, guarantee the oil level gaugember in the gas leakage of product nothing in service, the circumstances of the normal work of pressure release effectively promotes the transformer product quality, easy operation and no environmental pollution during the use have guaranteed the safety of transformer product operation.
Description
Technical field
The utility model relates to pick-up unit, particularly relates to a kind of oil immersion-type distribution transformer oil level indicator pressure testing device.
Background technology
Current oil immersion-type distribution transformer majority adopts the oil level indicator of band pressure relief valve; fuel tank can be protected; when oil-filled transformer be in operation break down time; because coil is overheated; a part of transformer oil is vaporized; in oil tank of transformer, pressure increases sharply, and at this moment utilizes pressure relief valve to send action, the protection unlikely distortion of fuel tank or explosion.Not used for the pick-up unit detected pressure relief valve in prior art, can not detected pressures relief valve whether existing defects.But directly the oil level indicator of band pressure relief valve is used on product, the stability of product can not be ensured reliably.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of oil immersion-type distribution transformer oil level indicator pressure testing device, solve the original defect without detecting, ensure oil level indicator in product runs without gas leakage, the situation that earth pressure release normally works, effective lifting power transformer product quality, simple to operate and non-environmental-pollution during use, ensure that the safety that power transformer product runs.
Oil immersion-type distribution transformer oil level indicator pressure testing device of the present utility model, comprises casing, air nozzle connector and oil level indicator seat; Described air nozzle connector and oil level indicator seat are all fixed on casing and communicate with cabinets cavity.
Further, described air nozzle connector is provided with the external thread for connecting supply air line.
Further, described oil level indicator seat is provided with the internal thread for connecting oil level indicator.
Further, also comprise a tensimeter connector and be fixedly connected on described tensimeter connector and the extension be communicated with cabinets cavity between casing and by tensimeter connector.
Further, also capping is comprised; Described capping is sealingly fastened in oil level indicator seat removably one to one for closing setting for corresponding oil level indicator.
Further, described oil level indicator seat is provided with multiple, and each oil level indicator seat and extension are arranged in box top and the arrangement in matrix.
The beneficial effects of the utility model are: oil immersion-type distribution transformer oil level indicator pressure testing device of the present utility model, can detected pressures relief valve whether existing defects, solve the original defect without detecting, ensure oil level indicator in product runs without gas leakage, the situation that earth pressure release normally works, effective lifting power transformer product quality, simple to operate and non-environmental-pollution during use, ensure that the safety that power transformer product runs.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Fig. 1 is structural representation of the present utility model, Fig. 2 is the vertical view of Fig. 1, and the oil immersion-type distribution transformer oil level indicator pressure testing device of the present embodiment, comprises casing 1, air nozzle connector 2 and oil level indicator seat 3, described air nozzle connector 2 and oil level indicator seat 3 are all fixed on casing 1 and communicate with casing 1 inner chamber, the oil level indicator of required detection is arranged on oil level indicator seat 3, valvular for band supply air line and air nozzle connector 2 are spun, open valve to carry out detected pressures relief valve to insufflation gas in casing 1 and can normally open and close and sensitivity, solve the original defect without detecting, ensure oil level indicator in product runs without gas leakage, the situation that earth pressure release normally works, effective lifting power transformer product quality, simple to operate and non-environmental-pollution during use, ensure that the safety that power transformer product runs, the steadying plate that a level is stretched out is fixed in casing 1 bottom surface, weight or testing staff can be placed in testing process directly ride the stability improving casing 1 and place on steadying plate on steadying plate.
In the present embodiment, described air nozzle connector 2 is provided with the external thread for connecting supply air line, matches, be convenient to dismounting with existing supply air line joint.
In the present embodiment, described oil level indicator seat 3 is provided with the internal thread for connecting oil level indicator; Match with oil level indicator structure, be convenient to the installation of oil level indicator and can enough strength of joint be produced.
In the present embodiment, also comprise a tensimeter connector 4 and to be fixedly connected between described tensimeter connector 4 and casing 1 and by the extension 5 of tensimeter connector 4 with casing 1 inner space, on tensimeter connector 4, a tensimeter can be installed, be convenient to observe the pressure condition in casing 1, the force value on tensimeter can be write down when earth pressure release valve events, judge whether oil level indicator meets the demands, improve accuracy of detection.
In the present embodiment, also comprise capping; Described capping is sealingly fastened in oil level indicator seat 3 removably one to one for being closed by corresponding oil level indicator seat 3, capping can be arranged on oil level indicator seat 3 when not using, extraneous dust impurity etc. is avoided to enter in casing 1, also can oil level indicator seat 3 be arranged multiple simultaneously, detect multiple oil level indicator simultaneously, when oil level indicator quantity is less than the quantity of oil level indicator seat 3, capping can be adopted to be closed by remaining oil level indicator seat 3, easy to use.
In the present embodiment, described oil level indicator seat 3 is provided with multiple, and each oil level indicator seat 3 and extension 5 are arranged in casing 1 end face and the arrangement in matrix, can detect multiple oil level indicator simultaneously, practical.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
