Description
Technical field
The invention belongs to field of electrical equipment, relate to a kind of main transformer on-load switch and exempt from dismounting quick sampling device.
Background technology
Existing transformer oil sample collecting work comprises following three contents: main transformer body simplifies oil sample collection, and main transformer body chromatogram oil sample gathers and main transformer on-load switch simplifies oil sample collection.Gather requirement according to existing cycle oil sample, a main transformer needs collection two secondary body to simplify oil sample and has to carry to simplify oil sample every year, and these oil samples are that the situation analysis that main transformer normally runs provides important foundation.
Wherein, main transformer on-load switch sampling valve is straight valve, first need pull down shrouding during sampling, then on oil sample collector, carrys additionally oil drum, turns on straight valve, uses sampling bottle access oil sample; Close straight valve after sampling, clean oil stain, reinstall closed, sampling terminates.Whole sampling process is comparatively loaded down with trivial details, the time expended on dismounting shrouding is more, due to inherent shortcoming during straight valve design, cause transformer oil in sampling process to splash and overflow, oily flow path direction and flow are difficult to hold, not only waste oil sample, also cause pollution to environment, the waste of oil sample also causes each collection capacity too much, thus decreases times of collection, cause the interval time of twice loaded switch repairing shorter, be about about 2 years.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide a kind of main transformer on-load switch simple and reasonable for structure to exempt from dismounting quick sampling device, this apparatus structure is simple, easy to use, is applicable to the main transformer of electric substation 110KV and 35KV.
According to technical scheme provided by the invention: a kind of main transformer on-load switch exempts from dismounting quick sampling device, it is characterized in that: hollow iron pipe afterbody is arranged in the mounting hole of base, hollow iron pipe outer circumference surface is set with copper block, and copper block lower end is arranged in base installing hole; The afterbody of described hollow iron pipe is taper, and at hollow iron pipe rear side face diameter to offering oiler, sets out hydraulic fluid port and oil recovery mouth at hollow iron pipe head, and described oil-out is connected with the hollow channel of oiler by hollow iron pipe.
As a further improvement on the present invention, described base is in the form of annular discs, and on base, circumferentially shape is uniform offers four connecting holes.
As a further improvement on the present invention, described copper block outer circumference surface is installed with round nut.
As a further improvement on the present invention, described oil-out is provided with the bolt for preventing oil outlet from coming off.
Compared with prior art, advantage is in the present invention: (1) the present invention, when sampling, without the need to dismounting, thus simplifies the course of work, shortens the whole working time.(2) when can overcome the sampling existing for original load switch sampling valve, transformer oil easily splashes and overflows, and oily flow path direction and flow are subject to the defect of the factor such as weather, equipment impact.(3) interval during the present invention can extend twice repairing, time needed for original load switch sampling is reduced to 5 minutes by 10 minutes, thus reduces the frequency of power cut of main transformer, reduce the job safety risk of maintainer, and the method is simple to operation, be conducive to promoting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is perspective structure schematic diagram of the present invention.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1 and Figure 2, base 1, outer side seal circle 2, oiler 3, sampling mouth 4, oil-out 5, copper block 6, hollow iron pipe 7, connecting hole 8, round nut 9 etc.
As shown in Figure 2, the present invention is that a kind of main transformer on-load switch exempts from dismounting quick sampling device, hollow iron pipe 7 afterbody is arranged in the mounting hole of base 1, the screw thread of hollow iron pipe 7 afterbody can be engaged compression with this body canal, by rotating the thimble turnover controlled in hollow iron pipe 7, when thimble is opened, oil flows through spherical oiler 3 and flows out, when closing, oiler 3 blocks by thimble, guarantee that transformer oil can not be excessive, hollow iron pipe 7 outer circumference surface is set with copper block 6, and copper block 6 lower end is arranged in base 1 mounting hole; The afterbody of described hollow iron pipe 7 is taper; and at hollow iron pipe 7 rear side face diameter to offering oiler 3; hydraulic fluid port 5 and oil recovery mouth 4 is set out at hollow iron pipe 7 head; described oil-out 5 is connected with the hollow channel of oiler 3 by hollow iron pipe 7; oil recovery mouth 4 reduces further compared to former sampling valve; make oil column can concentrate trickling out, the splashing of overflowing of oil sample can not be caused, while protection of the environment, effectively improve the tidiness of workplace.
Base 1 is in the form of annular discs, and on base 1, circumferentially shape is uniform offers four connecting holes 8, and connecting hole 8 is for fixedly mounting connection.
Described copper block 6 outer circumference surface is installed with round nut 9.
Oil-out 5 is provided with for spacing bolt, can prevent oil outlet from coming off and cause oil spout.
This product eliminates straight valve in existing apparatus and shrouding, and structure simplifies further, effectively can reduce the number of times of main transformer switch repairing after coming into operation, and reduces the technical risk because loaded switch repairing brings.
