Abstract
A kind of internal pressure release gear for voltage transformer, be set to be communicated with oil tank of transformer and absorb the capsule body (1) of the gas that to rise outside oil tank of transformer, by the gas that rises outside capsule body (1) absorption oil tank of transformer, the gas that makes to rise outside oil tank of transformer does not produce pressure, no longer air seal of rising outside oil tank of transformer is produced pressure in oil tank of transformer, therefore ensure that the inner pressure constant of voltage transformer, avoid occurring Seepage.
Description
technical field
The utility model relates to a kind of internal pressure release gear, especially a kind of internal pressure release gear for voltage transformer.
background technology
Power transformer is as the equipment of the different voltage class network of contact, it is component part in electric system and important, it is in the generating of electric system, transmission of electricity, distribution etc. are widely used in each, transport due to power transformer is far away and time gap is long, the temperature difference between manufactured place and transport destination may be larger, and voltage transformer is generally the transport of band oil, before transport, oil is noted apart from upper surface about 150mm, pasta top is dry air, because oil has the effect of expanding with heat and contract with cold, therefore as the voltage transformer of full-closed structure, in transportation, the pressure of its inside can change along with the change of temperature, if do not take special measure to be discharged in time by the pressure of inside to voltage transformer, because the change of pressure likely causes oil tank of transformer damaged, oil tank of transformer is caused to occur the situation of seepage, therefore the internal pressure release gear for voltage transformer is a kind of important transformer part, existing in the internal pressure release gear of voltage transformer, also there is no a kind of internal pressure release gear for voltage transformer.
summary of the invention
In order to overcome above-mentioned technical disadvantages, the purpose of this utility model is to provide a kind of internal pressure release gear for voltage transformer, therefore ensure that the inner pressure constant of voltage transformer, avoids occurring Seepage.
For achieving the above object, the technical scheme that the utility model is taked is: be set to be communicated with oil tank of transformer and absorb the capsule body of the gas that to rise outside oil tank of transformer.
When ambient temperature in transformer transporting process raises, internal pressure increases, in voltage transformer, gas enters in capsule body, alleviates tank internal pressure, prevents fuel tank from occurring seepage because pressure is excessive, owing to devising capsule body, absorb by capsule body the gas that to rise outside oil tank of transformer, the gas that makes to rise outside oil tank of transformer does not produce pressure, no longer air seal of rising outside oil tank of transformer is produced pressure in oil tank of transformer, therefore ensure that the inner pressure constant of voltage transformer, avoid occurring Seepage.
The utility model devises, also include casing, respirator, valve and supporting plate, capsule body to be arranged in the inner chamber body of casing and to be provided with pipeline and is communicated with oil tank of transformer, the pipeline that capsule body is communicated with oil tank of transformer is provided with valve, respirator is set to be communicated with the inner chamber body of casing and respirator is set to atmospheric envelope and is communicated with, and supporting plate is set to connect with oil tank of transformer also casing and is arranged on supporting plate.
The utility model devises, and casing is provided with opening and closing window.
The utility model devises, and capsule body is set to government rubber body.
The utility model devises, and respirator is set to silica gel respirator.
In the technical program, the capsule body of the gas that rises outside absorption oil tank of transformer is important technical characteristic, in the technical field of the internal pressure release gear for voltage transformer, has novelty, creativeness and practicality.
accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
detailed description of the invention
Fig. 1 is an embodiment of the present utility model, illustrate the present embodiment by reference to the accompanying drawings, include capsule body 1, casing 2, respirator 4, valve 5 and supporting plate 6, capsule body 1 to be arranged in the inner chamber body of casing 2 and to be provided with pipeline and is communicated with oil tank of transformer, the pipeline that capsule body 1 is communicated with oil tank of transformer is provided with valve 5, respirator 4 is set to be communicated with the inner chamber body of casing 2 and respirator 4 is set to atmospheric envelope and is communicated with, and supporting plate 6 is set to connect with oil tank of transformer also casing 2 and is arranged on supporting plate 6.
In the present embodiment, casing 2 is provided with opening and closing window.
In the present embodiment, capsule body 1 is set to government rubber body.
In the present embodiment, respirator 4 is set to silica gel respirator.
Before transformer transporting.By the opening and closing window of casing 2, air in capsule body 1 is discharged, again with voltage transformer UNICOM, open valve 5 and remain opening-wide state, when ambient temperature in transformer transporting process raises, internal pressure increases, in voltage transformer, gas enters in capsule body 1 by valve 5, alleviates tank internal pressure, prevents fuel tank from occurring seepage because pressure is excessive.When capsule body 1 expands, in casing 2, gas is discharged by respirator 4, due to the setting of respirator 4, prevents cabinet inside from entering steam, corrosion capsule body 1.
The utility model has lower feature:
1, owing to devising capsule body 1, the gas that to rise outside oil tank of transformer is absorbed by capsule body 1, the gas that makes to rise outside oil tank of transformer does not produce pressure, no longer air seal of rising outside oil tank of transformer is produced pressure in oil tank of transformer, therefore ensure that the inner pressure constant of voltage transformer, avoid occurring Seepage.
2, owing to devising casing 2 and respirator 4, ensure that the working environment of capsule body 1, extend the service life of capsule body 1.
3, owing to devising capsule body 1, casing 2, respirator 4, valve 5 and supporting plate 6, by the delivery mode of the gas that rises outside oil tank of transformer, the needs of the long-distance transportation of voltage transformer are met.
The technical characteristic connected with the capsule body 1 rising by gas outside absorption oil tank of transformer also having other is all one of embodiment of the present utility model; therefore in the internal pressure release gear technical field of voltage transformer, every be set to be communicated with oil tank of transformer and the technology contents absorbing the capsule body 1 of the gas that to rise outside oil tank of transformer all in protection domain of the present utility model.
