Description
Technical field
The utility model belongs to power transformation operation field, is related to main transformer, and especially a kind of load switch of transformer takes oil
Device.
Background technique
Transformer is most important electrical equipment in substation, and load switch of transformer is that transformer adjusts high and low pressure side change
The tap switch of ratio, since loaded switch needs to cut off load current, frequent arcing, the quality of insulating oil is lower, therefore has load
Switch interior insulation oil and main transformer interior insulation oil are not communicated with.It is provided according to Guo Wang incorporated business standard, loaded switch interior insulation
Oil needs routine test, and common transformer loaded switch insulating oil oil-containing groove is longer, take every time oil need to avoid it is residual in oil-containing groove
Oil, therefore waste more insulating oil.Repeatedly oil is taken to will lead to insulating oil oil level to be lower.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, provide it is a kind of facilitate testing crew to take oil,
Transformer Residual oil can be injected back into loaded switch fuel tank, and not introduce air pollution, final realize takes oily loss every time
Almost nil load switch of transformer oil taking apparatus.
The utility model technical scheme applied to solve the technical problem is:
A kind of load switch of transformer oil taking apparatus, including connecting flange, Electrocontrolled tee valve, take oil nozzle, two-way oil pump, storage
Oil Tank, spring, piston, oil level travel switch and oil pipe install spring, piston, the top of spring and oil storage in oil conservater
Cabinet top plate inner wall is fixedly mounted with, and bottom end and the piston of spring are fixedly mounted with, and oil level travel switch is installed in oil conservater upper inside wall, in oil conservater
One end of bottom plate connection one oil pipe of connection installs connecting flange in the other end of oil pipe, Electrocontrolled tee valve is installed on oil pipe, electricity
The interface connection of control triple valve takes oil nozzle, and the oil pipe passes through two-way oil pump.
Moreover, the Electrocontrolled tee valve is realized three two two intercommunicatings of valve export or is all closed.
Moreover, described takes oil nozzle to take oily wide-mouth bottle suitable for electrical test.
The advantages and positive effects of the utility model are as follows:
1, this oil taking apparatus by by transformer have carry oil-containing groove in Residual oil introduce oil conservater after, start to take oil, take oil it is complete
Finish, using two-way oil pump, the Residual oil in oil conservater is injected into load switch of transformer fuel tank, realizes and take oily damage every time
It consumes almost nil.And it can be avoided the case where getting Residual oil in oil-containing groove.
2, this oil taking apparatus installs spring and piston in oil conservater.It can be avoided insulating oil to contact with outside air, keep away
Exempt to pollute.
Detailed description of the invention
Fig. 1 is this load switch of transformer oil taking apparatus schematic diagram；
Fig. 2 main transformer oil-containing groove road schematic diagram.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by specific embodiment, and following embodiment is only retouched
The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of load switch of transformer oil taking apparatus, including connecting flange 1, Electrocontrolled tee valve 2, take oil nozzle 3, two-way oil pump
4, oil conservater 5, spring 9, piston 6, oil level travel switch 7 and oil pipe 8.Spring and piston are installed in oil conservater, spring
Top is fixedly mounted with oil storage cabinet top plate inner wall, and bottom end and the piston of spring are fixedly mounted with, and in the case where situation is not used, piston is under spring pressure
In oil conservater bottom, during taking oil, piston continues under the pressure of insulating oil to top movement, and compressed spring.?
Oil conservater upper inside wall installs oil level travel switch, one end of one oil pipe of connection is connected in oil conservater bottom, in the another of oil pipe
End installation connecting flange, installs Electrocontrolled tee valve on oil pipe, and the interface connection of Electrocontrolled tee valve takes oil nozzle, the oil pipe
By two-way oil pump.
Electrocontrolled tee valve may be implemented three two two intercommunicatings of valve export or all close.Connecting flange can and transformation
Device, which carries, sets oil-containing groove docking.It takes oil nozzle to be suitable for electrical test and takes oily wide-mouth bottle, oil conservater piston, which is realized, obtains insulating oil
And isolation, oil level travel switch can control Electrocontrolled tee valve and turn off or on.
The application method of the utility model are as follows:
Oil process orchid 12 is taken by what connecting flange was connected to 10 loaded switch fuel tank oil-containing groove 11 of transformer, first by automatically controlled three
1. and 2. port valves connect (flange port and take oil nozzle), discharge air in pipeline, after oil stream goes out, switching three-way valve is connected
3. 1. by (comprising taking Residual oil in pipeline) oily in loaded switch fuel tank injection oil conservater, to the close oil of oil conservater inner piston
1. and 2. after the travel switch of position, travel switch closes Electrocontrolled tee valve door, and Electrocontrolled tee valve door is connected, and testing crew starts
Oil normally is taken, after taking oil, switching Electrocontrolled tee valve door starts either-rotation motor to 1. and 3., by oil conservater interior insulation oil
It refills in load switch of transformer fuel tank, oil is taken to finish.
The utility model passes through laboratory test, complies fully with " electric power safety working regulation (power transformation portion, State Grid Corporation of China
Point) " in requirement, can apply at the scene.
Above-described is only preferred embodiments of the present invention, it is noted that for the ordinary skill of this field
For personnel, under the premise of not departing from utility model design, various modifications and improvements can be made, these belong to this reality
With novel protection scope.
