Abstract
The utility model relates to a multilevel compensation oil storing box, and the shell of the utility model is provided with a plurality of compensation ripple pipe cavity. The utility model is characterized in that the top parts of each springy ripple pipe and the closed shell are respectively welded; the ripple pipe end is provided with a weight steel plate; the ripple pipe and the closed shell are connected with a vacuum device through a vacuum pipe; an oil feeding port and an oil level instruction meter are arranged out of the shell; the ripple pipes are connected through the gas conducting pipe lines; and the end of the pipe line is connected with the air through a wet absorbing device. The utility model is characterized in that the ripple pipe has the similar shape and size with the shell to make the volume and the compensation volume reach the highest. The utility model makes the ripple pipe and the closed oil storing shell be positioned in the same vacuum status to fill oil and solves the oil filling problem of the prior patent; the ripple pipe compensation and the inner top surface of the shell are welded together; the weight steel plate of the lower end is connected with the air; the compensation ripple pipe adjusts the inflation and shrinking in the oil surface along with the change of the pressure and the temperature; the utility model has a balanced stress and has a long service life. Moreover the utility model is convenient to be filled or discharged oil.
Description
Technical field
The utility model relates to the oil conservator of transformer, a kind of multistage oil conservator of elastic bellows.
Background technology
Transformer has various ways such as drum type brake, expansion type with oil conservator, the oil mass that expands and when being used to hold transformer high temperature, but when transformer low temperature oil volume is shunk, oil conservator is because of low on fuel or do not have oil at all, make transformer be negative pressure state, cause the moisture intrusion and cause accident to take place.The applicant's patent formerly: " multistage compensation oil conservator " ZL02209676.0, in housing, establish a plurality of metal bellows compensators as shoe cream room, the heavy steel plate of bellows top establishing, corresponding priority valve is set between each bellows, and the lowermost level FlexbleJoint is communicated with the transformer oil conservator.Design philosophy is that liquid level is relatively higher than the big volume compensator of isodose in the compensator, thereby can reduce total innage, makes also corresponding the diminishing of volume of oil conservator.The oil that transformer comes when high temperature participates in moving in the compensator along sequence valve successively, can improve the operational reliability and the life-span of oil conservator.The problem that runs in actual use is: after the bellows inner chamber is vacuumized, under negative pressure to bellows in oiling, occurred just can not filling with oil, oil also can enter phenomenon in the vacuum equipment along vacuum tube.
Summary of the invention
The purpose of this utility model provides a kind of new multistage compensation oil conservator, overcomes above-mentioned shortcoming, makes compensation rate reach maximum.
The design's multistage compensation oil conservator, a plurality of compensation ripple tube chambers are arranged in the housing, it is characterized in that each elastic bellows and closed shell inner top weld respectively, bellows end has the counterweight steel plate, bellows is connected same vacuum equipment with closed shell is interior respectively by vacuum-pumping tube, housing has pouring orifice, oil level dial gauge outward, is communicated by the air guide pipeline between each bellows, and this pipeline end communicates with atmosphere through dehydrating breather.
The advantage of the design's multistage compensation oil conservator is: bellows and shell shape, size are close, make volume and compensation rate reach maximum.The design allows bellows and airtight oil storage housing the inside be in oiling under the same vacuum degree state, has solved the oiling problem of patent formerly.The bellows compensated cavity has the counterweight steel plate with the weldering of housing inner top surface for one, lower end and communicates with atmosphere, and bellows can keep good air-tight state in frequent motion, can not produce residues such as analyte, can not produce transformer oil and pollute.The compensation bellows in air pressure and temperature variant oil level, regulates self expand, contraction, stress equalization, long service life.The oil conservator oiling or the oil extraction of this form are also more convenient.

Embodiment
Multistage compensation oil conservator, see Fig. 1-3: a plurality of compensation bellows 3 cavitys are arranged in the housing 6, it is characterized in that a plurality of metallic elastic bellowss 3 and closed shell 6 inner tops difference solder bond, bellows end face weld counterweight steel plate 4, be connected same vacuum equipment respectively by vacuum tube 7 in each metal bellows 3 and the closed shell 6, establish Pressure gauge, valve 8 in the pipeline 7; Oil level dial gauge 1 is established in the housing side, is communicated by wireway 9 between each bellows, and this pipeline end communicates with atmosphere through dehydrating breather.The oil level dial gauge is established in the closed shell side, and has indicator in connecting rod and the housing to rotate ball float 2 to link to each other, and closed shell 6 is divided into into and out of hydraulic fluid port 5.
The design's oil conservator is for increasing compensation volume, and is close a plurality of bellows design one-tenth and hull shape, size, sees Fig. 4, Fig. 5: cross-sectional shape of bellows can be square, circular arc line and the straight line or the combination of circle etc.
User mode: closed shell 6 is connected same vacuum equipment with bellows 3 respectively by vacuum tube 7, vacuumizes simultaneously, begins oiling when reaching same vacuum degree in two kinds of cavitys.According to design considerations such as oil temperature, ambient temperatures, when certain value is arrived in oiling, ball float 2 floats with oil level by connecting rod, oil level gauge 1 pointer shows oil level, when liquid level reaches setting, close the valve 8 of vacuum line, remove vacuum in the bellows, the dehumidifier of vacuum tube end is opened, and compensator communicates with atmosphere by pipeline.
Claims (2)
1. multistage compensation oil conservator, a plurality of compensation ripple tube chambers are arranged in the housing, it is characterized in that each elastic bellows and closed shell inner top weld respectively, bellows end has the counterweight steel plate, bellows is connected same vacuum equipment with closed shell is interior respectively by vacuum-pumping tube, housing has pouring orifice, oil level dial gauge outward, is communicated by the air guide pipeline between each bellows, and this pipeline end communicates with atmosphere through dehydrating breather.
