Technical field
A kind of recharging oil device for transformer is the utility model is related to, more particularly to a kind of oil immersed type station local coordinate frame is mended
Oily dolly.
Background technology
Station local coordinate frame leakage of oil problem is always to perplex a problem of power department in transformer station.Station local coordinate frame oozes
Oil leak can not only influence carrying out production strictly in line with rules and regulations for transformer station, the safe operation of entail dangers to station local coordinate frame when serious, cause its stoppage in transit.One
There is leakage of oil in denier station local coordinate frame, it is necessary to maintainer can in a short time to occur oil leak equipment carry out mending-leakage after again
Carry out repairing work, it is ensured that its reliability service.
At present, the station local coordinate frame repairing of most of transformer station works generally all by maintainer by oil can or oil drum hand
It is dynamic to carry out.Weak point：
1st, maintainer needs to carry out repairing operation by stair activity, and security is not high；
2nd, such as a large amount of repairings work (such as processing transformer bottom fuel outlet valve leakage of oil defect), prior art will be highlighted
Time-consuming, delays the equipment telegram in reply time；
3rd, impurity, moisture or bubble are there may be in the transformer oil injected, station is influenceed and becomes safe and stable operation；
4th, live repairing needs to carry the sundry miscellaneauses such as oil drum, oil pump, complex operation, and to the environmental sanitation in transformer station
Certain influence is produced, operating efficiency is not high.
The device that correlation is have developed for the people that solve the above problems is used to carry out oily benefit, but still exists necessarily
Contain more bubble in defect, such as oil.
Utility model content
The purpose of this utility model is that providing one kind can give station local coordinate frame quick repairing, and effectively reduces gas in oil
The oil immersed type station local coordinate frame repairing dolly of bubble.
This oil immersed type station local coordinate frame repairing dolly provided by the utility model, it includes movable tray and is arranged at work
Fuel reserve tank on dynamic chassis, fuel reserve tank is interior to be provided with heater, and fuel reserve tank is externally provided with outlet line and oil pump, set in outlet line
There is filter.
In order to improve the reliability of heating, the heater is set to include adding thermal resistance and air switch, adding thermal resistance is set
The bottom position being placed in the fuel reserve tank.
In a specific embodiment, the outlet line is made to include the first flowline and the second flowline, first is fuel-displaced
Pipe is arranged between the fuel reserve tank and the oil pump, and the second flowline is connected to the output end extroversion transformer repairing of oil pump.
In order to improve the cleannes of oil, be easy to adjust fuel delivery, one end of first flowline is set to pass through the first filtering
Device is communicated in the oil-out opening position of the fuel reserve tank, and the first flowline is provided with flow control valve.
In order to further reduce impure, bubbles volume in oil, the second filtering is provided with the oil outlet end of second flowline
Device.
In a specific embodiment, it is screen pack to make the first filter, and the second filter is oil strainer.
For the ease of controlling fuel delivery, it is furnished with frequency converter to the oil pump.
For proof strength, cleannes are improved, make the trolley that the movable tray is stainless steel.
Oil storage tank, outlet line and oil pump are integrated on movable tray by the utility model, reduce substation field station
With the complexity for becoming repairing operation sequence, efficiency is improved；And fuel reserve tank can be carried out by heater before repairing
Preheat in advance, can effectively reduce moisture, air bubble content in transformer oil, improve reliability.
Brief description of the drawings
Fig. 1 is the schematic front view of one preferred embodiment of the utility model.
Illustrate sequence number：
1-movable tray, 2-fuel reserve tank, 3-heater, the 4-the first flowline, the 5-the second flowline, 6-the first
Filter, the 7-the second filter, 8-flow control valve, 9-oil pump, 31-adding thermal resistance, 32-air switch.
Embodiment
As shown in figure 1, the present embodiment provide this oil immersed type station local coordinate frame repairing dolly, it include movable tray 1,
Fuel reserve tank 2, heater 3, the first flowline 4, the second flowline 5, first filter 6, the second filter 7, flow control valve 8
With the oil pump 9 with frequency converter.
Movable tray 1 is designed as trolley made of stainless steel material in the present embodiment, with proof strength and cleaning
Degree.Heater 3 is designed as including adding thermal resistance 31 and there is the air switch 32 of creepage protection function, adding thermal resistance 31 is set
It is placed in fuel reserve tank 2, the temperature of preheating is controlled by air switch, when adding thermal resistance will be heated to certain temperature space-time in fuel tank
Air cock disconnects, and stops heating；Fuel reserve tank is preheated in advance using preceding 2, using adding thermal resistance, can be effectively reduced
Moisture, air bubble content in transformer oil, improve the purity of transformer oil.It is screen pack that first filter 6, which is selected, screen pack
The oiler at the oil-out of fuel reserve tank 2 with the first flowline is arranged to connect, the oil-out of the first oil-out and oil pump it is defeated
Enter end connection, the output end of oil pump is connected to the second flowline, and the second filter is the oil for being arranged at the second flowline exit
Filter.
The present embodiment has carried out integration using trolley to recharging oil device, effectively reduces substation field station
With the complexity for becoming repairing operation sequence, environmental pollution is reduced；Fuel reserve tank is preheated in advance using adding thermal resistance simultaneously,
Moisture, the air bubble content in transformer oil can effectively be reduced；And when in-line sets first filter to cause oil pumping
Wait just can tentatively be filtered to oil, and the second filter effectively reduces the impurity and bubble in oil to the further filtering of oil；Return
Oil pump configures frequency converter so that the pump oil flow of oil pump can quantify control by changing frequency of supply；Additionally by fuel-displaced
The flow control valve of pipeline, it is possible to control the speed of oil stream, reduce bubble caused by oil stream during oil pumping oiling.So this
Embodiment has broken traditional repairing mode, can give the quick repairing of station local coordinate frame, and effectively reduce be injected into it is miscellaneous in oil
Matter, moisture and bubble.
The present embodiment utilizes certain transformer station's power failure machine meeting in practice, and repairing has been carried out to certain 35kV station local coordinate frame
Operation, needing two people in the past, above high-altitude carries out the work of repairing simultaneously, and only needing a people now, above high-altitude can is completed, and in oil
The more original direct filling oil method of bubble has larger reduction, ensure that the safe and reliable operation of equipment operation；Save a large amount of
The repairing working time, reduce manpower consumption, and the station local coordinate frame running situation is good at present, and equipment safely can may be used
The operation leaned on.
