Description
Technical field
The present invention, which relates to, belongs to electric power overhaul field, is exactly a kind of Repair of Transformer oil-flow control apparatus.
Background technology
Power transformer applied in 500kV voltage class it is most of be oil-filled transformer.If transformer is being transported
Broken down in row, it is necessary to by its interruption maintenance., it is necessary to which the oil in transformer is released outside transformer body during maintenance.Due to
Transformer power off time limits, and drain the oil all can not all discharge transformer oil every time.According to Repair of Transformer position not
Together, also there is different requirements to the transformer oil amount of draining the oil.The overall principle is to control the transformer amount of draining the oil, existing filling type
Transformer can not stop draining the oil in time well.
The content of the invention
To solve the above problems, it is an object of the invention to provide a kind of Repair of Transformer oil-flow control apparatus.
The present invention to achieve the above object, is achieved through the following technical solutions:Including flowmeter, flowmeter passes through two hold-carryings
Blue connected pipes, first annular sliding block and the second ring slider, first annular cunning are symmetrically housed in the both sides of oil pipe flow meter
Block is provided with screwed hole, and screw rod is housed on screwed hole, and the second ring slider is provided with annular groove, anchor ear is set with annular groove,
Drop handle is fixedly connected with anchor ear.The material of the anchor ear is doping formula High-strength steel, the material of the doping formula High-strength steel
Matter (weight) component is by mass percentage:
The .041-0 .043% of carbon 0;
The .3-0 .4% of chromium 0;
The .1-0 .2% of calcium 0;
0 .05-0 .06% of silver;
The .02-0 .03% of magnesium 0;
Lead tungstate 0.57-0.58%;
Surplus is iron.
Further to realize the purpose of the present invention, following technical scheme can also be used:The length of described screw rod is more than
The length of screwed hole.Described anchor ear is made up of two symmetrical semicircular rings, and one end is hingedly connected together, and the other end leads to
Cross and be bolted to together.Also include flow line, flow line connects the first oil pipe and the second oil pipe, and the second oil pipe connects the first valve
Door, the first valve connect oil pipe, the valve of another termination second of oil pipe, and the second valve connects the 3rd oil pipe, and the second oil pipe connects the 3rd valve
Door, the 3rd valve connect the 3rd oil pipe, and the 3rd oil pipe connects oil pump entrance point, and fuel pump outlet terminates the 4th oil pipe.
The advantage of the invention is that:The material of the anchor ear of the present invention is doping formula High-strength steel, compared to common steel
Material, the improvement well that yield strength obtains, we are had found in carbon, chromium, calcium, silver, magnesium and iron content identical through overtesting
In the case of, it is doped into and the intensity of formula High-strength steel is adulterated after lead tungstate can be improved, particularly wolframic acid lead content reaches
During 0.57-0.59%, the yield strength of doping formula High-strength steel obtains rising to for certain numerical value, reaches 248-249Mpa.This hair
The setting of bright middle flowmeter, which to drain the oil, measures control, and the setting of drop handle make it that device is easy to carry, and the use of the device is big
The big time for reducing Repair of Transformer, maintenance duration is shortened, improves the operational reliability of transformer.In order that drop handle is firm
Gu reliable, the length of the screw rod on first annular sliding block is more than the length of screwed hole, when tightening screw rod, you can fixation is first annular
Sliding block, due to being equipped with anchor ear on the second ring slider, two anchor ears are fixedly connected with the both ends of drop handle, therefore the second ring slider
It can not move left and right, so as to which drop handle will not double swerve.The present invention also has compact, manufacturing cost simple for structure cheap and used
The advantages of easy.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;Fig. 2 is partial sectional view in Fig. 1;Fig. 3 is anchor ear schematic diagram in Fig. 1;
Fig. 4 is pipeline schematic diagram.
Brief description of the drawings:1 drop handle, 2 flowmeter, 3 flange, 4 screw rod, the 5 first annular annulars of 6 annular groove of sliding block 7 second are sliding
The oil pump 16 of 13 second 18 first valve of oil pipe of block 8 anchor ear, 9 oil pipeline, 10 bolt, 11 flow line, 12 first oil pipe 15
The oil pipe of 17 19 second the 3rd the 3rd oil pipe 22 of valve 21 of valve 20 of screwed hole of flange the 4th.
Embodiment
A kind of Repair of Transformer fuel-flow control of the present invention, as depicted in figs. 1 and 2, including flowmeter 2, flowmeter 2
By the connected pipes 9 of two end flanges 3, in the both sides of the flow meter 2 of oil pipe 9 symmetrically equipped with the first annular annular of sliding block 5 and second
Sliding block 7, first annular sliding block 5 are provided with screwed hole 17, and screw rod 4 is housed on screwed hole 17, and the second ring slider 7 is provided with annular
Groove 6, anchor ear 8 is set with annular groove 6, drop handle 1 is fixedly connected with anchor ear 8.The setting of flowmeter 2 cause overhaul transformer some
Drained the oil during position and measure control, the setting of drop handle 1 is easy to carry when causing use device.The material of the anchor ear 8 is doping
Formula High-strength steel, material (weight) component of the doping formula High-strength steel are by mass percentage:
The .041-0 .043% of carbon 0;
The .3-0 .4% of chromium 0;
The .1-0 .2% of calcium 0;
0 .05-0 .06% of silver;
The .02-0 .03% of magnesium 0;
Lead tungstate 0.57-0.58%;
Surplus is iron.
The material of the anchor ear 8 of the present invention is doping formula High-strength steel, and compared to common iron and steel material quality, yield strength obtains
Improvement well, we through overtesting find in the case of carbon, chromium, calcium, silver, magnesium and iron content identical, be doped into wolframic acid
The intensity of formula High-strength steel is adulterated after lead to be improved, and when particularly wolframic acid lead content reaches 0.57-0.59%, adulterate formula
The yield strength of High-strength steel obtains rising to for certain numerical value, reaches 248-249Mpa.
In order that drop handle 1 is solid and reliable, the length of the screw rod 4 on first annular sliding block 5 is more than the length of screwed hole 17, twists
During tight screw rod 4, you can fixed first annular sliding block 5, due to being equipped with anchor ear 8, two anchor ears 8 and drop handle 1 on the second ring slider 7
Both ends be fixedly connected, therefore the second ring slider 7 can not move left and right, so as to which drop handle 1 will not double swerve.
In order that anchor ear 8 more convenient during drop handle 1, described must be installed by two symmetrical semicircular ring structures
Into one end is hingedly connected together, and the other end is bolted on together.
When overhauling transformer position, in order to accurately control oil mass of draining the oil, flow line 11 connects the first oil pipe 12 and second
Oil pipe 13, the second oil pipe 13 connect the first valve 18, and the first valve 14 connects oil pipe 9, the second valve of another termination 19 of oil pipe 9, and
Two valves 19 connect the 3rd oil pipe 21, and the second oil pipe 13 connects the 3rd valve 20, and the 3rd valve 20 connects the 3rd oil pipe 21, the 3rd oil pipe 21
Connect the entrance point of oil pump 15, the outlet of oil pump 15 the 4th oil pipe 22 of termination.When needing to release whole oil masses in transformer, first is closed
The valve 19 of valve 18 and second, the 3rd valve 20 is opened, open oil pump 15, until the 4th oil pipe 22 is discharged without oil.Work as needs
When controlling the amount of draining the oil, the 3rd valve 20 is closed, opens the first valve 18 and the second valve 19, opens oil pump 15, observes flowmeter
2, when the pointer of flowmeter 2 instruction amount of draining the oil needed for, close the valve 18 of oil pump 15 and first.
Technical scheme is not restricted in the range of embodiment of the present invention.The not detailed description of the present invention
