Abstract
The utility model discloses an oil pressure balance device for a capsule oil conservator. The oil pressure balance device is arranged on the oil conservator; an oil level gauge is arranged in the oil conservator; a gas relay pipe joint is arranged at the lower part of the oil conservator; an exhaust pipe is arranged above the oil conservator; and a moisture absorption device is arranged at a valve end of the exhaust pipe. As the moisture absorption device is additionally arranged at the valve end of the exhaust pipe of the oil conservator, the valve is in a normally open state to balance the pressure in the oil conservator. When the pressure in the oil conservator is over-high due to gas accumulation, air in the oil conservator is exhausted through the exhaust pipe and the moisture absorption device; and when the pressure in the oil conservator is reduced due to the fact that the oil surface in the oil conservator falls down, gas is sucked into the oil conservator through the moisture absorption device and the exhaust pipe; and as the moisture absorption device can absorb water vapor and impurities in air, the quality of insulating oil in the oil conservator can be guaranteed. Proved by experiments, the method can effectively solve the false oil level defect of the capsule oil conservator.
Description
Technical field
The utility model belongs to transformer station's electric equipment parts technical field, particularly a kind of capsule-type oil conservator oil pressure bascule.
Background technology
Oil conservator is one of primary clustering of transformer, and its effect is volumetric expansion or the contraction that the compensation insulating oil produces because of variations in temperature, guarantees to be full of oil in the oil-filled equipment body always.Common oil conservator has three types of open type, capsule-type or diaphragm type and bellows-types.That the capsule-type oil conservator is installed in oil conservator is one airtight, can bear the capsule of elevated pressures, by capsule insulating oil and outside air are separated, and stop steam to enter capsule by dehydrating breather, in service, capsule floats on the pasta, carry out air-breathing or exhaust along with pasta rises or descends,, guarantee to be full of insulating oil in the transformer body always with pressure at both sides inside and outside this autobalance capsule.Main transformer is in long-time running, having portion gas enters in the oil conservator, oil conservator extraneous air under negative pressure condition infilters in the cabinet, gas in the fuel tank also can enter in the cabinet, and these gases have occupied the expiration that certain position has influenced capsule in the oil conservator, causes to be malleation in the oil conservator when gas is too much, make oil meter false pasta occur, when the main transformer load increased the temperature rising, insulating oil also can cause the oil in the cabinet outwards to overflow from respirator because of expansion pasta rising oil conservator internal pressure height.
The utility model content
The utility model provides a kind of capsule-type oil conservator oil pressure bascule that solves the false oil level fault of capsule-type oil conservator, uses this device interior pressure of balance oil conservator at any time, thereby effectively solves the problem of false oil level.
A kind of capsule-type oil conservator oil pressure bascule is arranged on the oil conservator, in the described oil conservator oil level gauge is set, and the bottom is provided with the Buchholz relay pipe joint, and the top of described oil conservator is provided with blast pipe, and the valve end of described blast pipe is provided with dehydrating breather.
Because the utility model installs a dehydrating breather additional at oil conservator exhaust valve place, valve is in normally open, is used for the pressure in the balance oil conservator.When the oil conservator internal cause is saved bit by bit gas and is caused hypertonia, air in the oil conservator is discharged through blast pipe and dehydrating breather, when the decline of the pasta in the oil conservator causes the cabinet internal pressure to reduce, suck gas by dehydrating breather and blast pipe, because steam and the impurity of dehydrating breather in can purifying air, therefore can guarantee the quality of insulating oil in the cabinet.Through experiment showed, that this method can effectively solve the false oil level fault of capsule-type oil conservator.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a user mode reference diagram of the present utility model.
Embodiment
As shown in Figure 1: a kind of capsule-type oil conservator oil pressure bascule, be arranged on the oil conservator 1, in the described oil conservator 1 oil level gauge 2 be set, the bottom is provided with Buchholz relay pipe joint 4, the top of described oil conservator 1 is provided with blast pipe 3, and the valve end of described blast pipe 3 is provided with dehydrating breather 5.
Because the utility model valve place of blast pipe 3 on oil conservator 1 installs a dehydrating breather 5 additional, valve is in normally open, be used for the pressure in the balance oil conservator, when the oil conservator internal cause is saved bit by bit gas and is caused hypertonia, air in the oil conservator 1 is discharged through blast pipe 3 and dehydrating breather 5, when the decline of the pasta in the oil conservator 1 causes the cabinet internal pressure to reduce, suck gas by dehydrating breather 5 and blast pipe 3, because steam and the impurity of dehydrating breather in can purifying air, therefore can guarantee the quality of insulating oil in the cabinet.Through experiment showed, that this method can effectively solve the false oil level fault of capsule-type oil conservator.
Claims (1)
1. capsule-type oil conservator oil pressure bascule, be arranged on the oil conservator, in the described oil conservator oil level gauge be set, the bottom is provided with the Buchholz relay pipe joint, the top of described oil conservator is provided with blast pipe, it is characterized in that: the valve end of described blast pipe is provided with dehydrating breather.
