Abstract
The utility model discloses an oil pumping and injecting device for a load switch of a transformer, which can realize the oil change for the load switch without uncovering and using a special oil pump. The device comprises an oil delivery pipe, a gas delivery pipe, an air valve and an oil valve, wherein the gas delivery pipe and the oil delivery pipe are respectively connected with the air valve and the oil valve; one end of the gas delivery pipe is communicated with the top end inside of the load switch, and the other end of the gas delivery pipe is placed outside the load switch; and one end of the oil delivery pipe is communicated with the bottom end inside of the load switch, and the other end of the oil delivery pipe is placed in an oil storage container arranged outside the load switch. By adopting the structure, the oil pumping and injecting device for the load switch of the transformer has simple structure, is convenient to operate, does not need the special oil pump and can carry out the oil pumping and injecting for the load switch without uncovering, so as to meet the requirements of a majority of industrial and mining enterprises.
Description
Technical field
The utility model relates to a kind of transformer loaded switch equipment, and especially a kind of transformer loaded switch is taken out oiling device.
Background technology
In the use of transformer loaded switch, the 10kV loaded switch generally after action 3 to 5,000 times, change the transformer oil in the switch, and the 10kV loaded switch does not generally have the special oiling device of taking out, change oil and need open switch cover, could be by special oil pump with the transformer oil sucking-off.Destroy the switch sealing easily and often uncap, also bring booty into switch easily.Part 35kV loaded switch is provided with takes out oiling device, this takes out oiling device also needs special oil pump cooperation to realize, general industrial and mining enterprises' majority does not possess this condition, causes prolonging oil changing interval or does not change oil, and buries very big hidden danger for the transformer safe operation.
The utility model content
The technical problems to be solved in the utility model provides a kind of can need not and uncaps, and oil pump that need not be special just can realize that the transformer loaded switch that loaded switch is changed oil takes out oiling device.
For addressing the above problem, a kind of transformer loaded switch of the present utility model is taken out oiling device, comprises petroleum pipeline, appendix and air valve and fuel tap, and appendix is connected air valve and fuel tap respectively with petroleum pipeline; One end of described appendix is communicated to the top of loaded switch inside, and the other end is positioned over the loaded switch outside; One end of described petroleum pipeline is communicated to the bottom of loaded switch inside, and an end is put into the oil vessel that is arranged on the loaded switch outside.
The transformer loaded switch of the utility model structure is taken out oiling device, in use, as need loaded switch is pumped, only need open air valve and fuel tap, the inside of loaded switch is communicated with ambient atmosphere by appendix, by appendix loaded switch inside is applied malleation or by petroleum pipeline loaded switch inside applied negative pressure, the transformer oil that it is inner is extracted out.At this moment oil vessel is positioned over the position that is lower than the loaded switch bottom, according to siphon principle, the transformer oil of loaded switch inside will flow out automatically.When needs carry out oiling to loaded switch, only oil vessel need be placed the position that is higher than the loaded switch top, can carry out oiling to it.
Adopt the transformer loaded switch of the utility model structure to take out oiling device, simple in structure, handled easily need not special oil pump equipment, and realizes the covered operation that just can take out oiling to loaded switch, can satisfy the demand of most of industrial and mining enterprises.
Description of drawings
Fig. 1 takes out the structural representation of oiling device oil pumping state for the utility model transformer loaded switch.
Fig. 2 takes out the structural representation of oiling device oiling state for the utility model transformer loaded switch.
Embodiment
In order to make those skilled in the art person understand technical solutions of the utility model better, the utility model is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 1, 2, a kind of transformer loaded switch of the present utility model is taken out oiling device, comprises petroleum pipeline 2, appendix 3 and valve 4, and appendix 3 and petroleum pipeline 2 are respectively by air valve and fuel tap in the valve 4; One end of described appendix 3 is communicated to the top of loaded switch 1 inside, and the other end is positioned over loaded switch 1 outside; One end of described petroleum pipeline 2 is communicated to the bottom of loaded switch 1 inside, and an end is put into the oil vessel that is arranged on loaded switch 1 outside.
The transformer loaded switch of the utility model structure is taken out oiling device, in use, as need loaded switch 1 is pumped, only need open air valve and fuel tap in the valve 4, the inside that makes loaded switch 1 communicates with ambient atmosphere by appendix 3, apply malleation or apply negative pressure by 2 pairs of loaded switch inside of petroleum pipeline by 3 pairs of loaded switch 1 inside of appendix, the transformer oil that it is inner is extracted out.At this moment oil vessel 5 is positioned over the position that is lower than loaded switch 1 bottom, according to siphon principle, the transformer oil of loaded switch 1 inside will flow out automatically.When needs carry out oiling to loaded switch 1, only oil vessel 5 need be placed the position that is higher than loaded switch 1 top, can carry out oiling to it.
Adopt the transformer loaded switch of the utility model structure to take out oiling device, simple in structure, handled easily need not special oil pump equipment, and realizes the covered operation that just can take out oiling to loaded switch, can satisfy the demand of most of industrial and mining enterprises.
