Abstract
The utility model relates to a vacuum-pumping communicating pipe for an oil-immersed transformer, which belongs to the field of oil-immersed transformers, and comprises a main pipeline joint connected with a vacuum pump, a spherical supporting part and a plurality of branch pipeline joints, wherein the main pipeline joint is communicated with all the branch pipeline joints through the spherical supporting part, and valves are arranged on the main pipeline joint and all the branch pipeline joints respectively. The vacuum-pumping communicating pipe provided by the utility model has the advantages of convenience in connection, large amount of the branch pipelines, low manufacturing cost, and the like, and can effectively improve the vacuum-pumping efficiency.
Description
Technical field
The utility model relates to the oil immersed transformer field, and a kind of specifically oil immersed transformer vacuumizes the connecting tube of usefulness.
Background technique
In the large oil immersed formula oiling transformer process, have air in the transformer and moisture is remaining, in service as transformer work, transformer contains gas and exceeds the insulating oil safety standard requirements, makes insulation not enough, will cause discharge, influences the normal use of transformer.For fear of the problems referred to above; need before the oiling transformer to use vacuum pump that it is vacuumized; in vacuum; having a plurality of pipelines connects; because pipeline more complicated; through regular meeting the situation that several pipes cross simultaneously takes place, can reduce the speed that vacuumizes greatly, influence vacuumizes efficient.
Summary of the invention
In order to overcome above defective, the purpose of this utility model provides the connecting tube that a kind of oil immersed transformer vacuumizes usefulness.
The technical solution of the utility model is: a kind of oil immersed transformer vacuumizes the connecting tube of usefulness, it is made up of the main pipe joint that is connected with vacuum pump, spherical supporting and a plurality of subtube joint, described main pipe joint interlinks by spherical supporting and each subtube joint, is respectively equipped with valve on described main pipe joint and each subtube joint.
The cross-section area that the utility model has also designed described main pipe joint is not less than the cross-section area of each subtube joint.
The quantity that the utility model has also designed described subtube joint is at least four
The described valve seal mode that also designed the utility model adopts the oil resisting rubber jointing sealing.
Working procedure of the present utility model is: the main pipe joint interlinks by spherical supporting and each subtube joint, be respectively equipped with valve on described main pipe joint and each subtube joint, during use, open the valve of vacuum pump main pipe joint, open each subtube valve, as not having connecting pipeline on this subtube, just need not open the valve on time pipeline.
The beneficial effects of the utility model are: 1, the utility model effectively raises and vacuumizes efficient.
2, the utlity model has easy to connect, be in charge of characteristics such as many, low cost of manufacture.
3, the utility model has improved the flexibility that pipeline connects, and is easy to use.

Embodiment
As shown in Figure 1, a kind of oil immersed transformer vacuumizes the connecting tube of usefulness, it is characterized in that: it is made up of the main pipe joint 1 that is connected with vacuum pump, spherical supporting 2 and a plurality of subtube joint 3, described main pipe joint 1 interlinks with each subtube joint 3 by spherical supporting 2, is respectively equipped with valve 4 on described main pipe joint 1 and each subtube joint 3.
The cross-section area that the utility model has also designed described main pipe joint 1 is not less than the cross-section area of each subtube joint 3.
The quantity that the utility model has also designed described subtube joint 3 is at least four.
The utility model has also designed described valve 4 sealing means and has adopted the oil resisting rubber jointing sealing.
The utility model valve 4 can adopt check valve; only allow the medium one-way flow; in the vacuum; when causing vacuum pumping device to shut down because of power failure, fault or other emergencies; be subjected to the restriction of check valve; lubricant oil in the vacuum pump can't be gone in the transformer by suck-back, thereby can avoid the pollution of greasy dirt to transformer, the Safety performance height.
Working procedure of the present utility model is: main pipe joint 1 interlinks with each subtube joint 3 by spherical supporting 2, be respectively equipped with valve 4 on described main pipe joint 1 and each subtube joint 3, during use, open the valve 4 of vacuum pump main pipe joint 1, open each subtube valve 4, as not having connecting pipeline on this subtube, just need not open the valve 4 on time pipeline.
The beneficial effects of the utility model are: 1, the utility model effectively raises and vacuumizes efficient.
2, the utlity model has easy to connect, be in charge of characteristics such as many, low cost of manufacture.
3, the utility model has improved the flexibility that pipeline connects, and is easy to use.
Above-described mode of execution is the utility model preferred forms; be not to limit concrete practical range of the present utility model with this; scope of the present utility model comprises and is not limited to this embodiment, and the equivalence that all shapes according to the utility model, structure are done changes and all comprises protection domain of the present utility model.
