Abstract
The utility model provides a tool for disassembly and assembly of a transformer gas relay. The tool for disassembly and assembly of the transformer gas relay is characterized by comprising two oil pipe snap rings symmetrically arranged, two connecting rods respectively connected with the two oil pipe snap rings, and an extensible pull rod connected with the two connecting rods. Oil pipes arranged at two ends of the gas relay are respectively and conveniently through the two oil pipe snap rings composed of upper clamp splices and lower clamp splices, then the oil pipes can be conveniently separated to the two ends of the gas relay through rotation of the extensible pull rod for connection of the two oil pipe snap rings, and therefore the gas relay is steadily disassembled and assembled, and the gas relay and connecting flanges are not damaged. Meanwhile, sealing rings between the oil pipes and the flanges can be accurately installed in place, and the problem of oil leakage caused by displacement of assembly sealing pieces is avoided. The tool for disassembly and assembly of the transformer gas relay has the advantages of being simple in structure, convenient to use, flexible in operation, and the like. The tool for disassembly and assembly of the transformer gas relay is not only applicable to disassembly and assembly of the transformer gas relay, but also widely applicable to disassembly and assembly of valves, connecting parts on various pipelines, and the like.
Description
Technical field
The utility model relates to a kind of dismantling device, and particularly a kind of instrument that is exclusively used in dismounting transformer Buchholz relay belongs to the transformer maintenance technical field.
Background technology
Buchholz relay is the main protection of transformer, and it is installed on the oil pipe under the installation for transformer by flange.When carrying out transformer cycled recondition, need the dismounting Buchholz relay, to carry out verification, on the oil pipe under the installation for transformer of again it being packed into afterwards.Because there is larger stress in Buchholz relay two ends oil pipe to it, prior art is by conventional instruments such as flat mouth bottle opener or little crowbars, prize by force the slit at Buchholz relay and adpting flange place, Buchholz relay could be split out, so very easily to relay and ring flange injury.In addition, it is very inconvenient that the instruments such as use flat mouth bottle opener shift out relay, and personnel and equipment damage accident easily occur.Moreover in installation process, because the effect of pipe stress easily causes the seal displacement, cause the poorly sealed and oil impregnate of attaching parts, thereby affect transformer moves normally, makes power supply reliability decline.Therefore be necessary prior art is improved.
Summary of the invention
The purpose of this utility model is to provide the instrument of convenient, fast, the safe dismounting transformer of a kind of energy Buchholz relay.
The utility model is finished by following technical proposal: a kind of instrument of dismounting transformer Buchholz relay, it is characterized in that it comprises symmetrically arranged two oil pipe snap rings, the connecting rod that links to each other with two oil pipe snap rings respectively, the telescopic lever that connects two connecting rods, in order to two oil pipe snap rings are separately fixed on the oil pipe at transformer Buchholz relay two ends, after connecting connecting rod on the two oil pipe snap rings by telescopic lever again, can be by the adjusting of telescopic lever, after the oil pipe axial displacement with transformer Buchholz relay two ends, easily pull down the transformer Buchholz relay.
Described oil pipe snap ring comprises on it that with the upper and lower fixture block of groove, the groove of upper and lower fixture block is connected to respectively on the oil pipe, and upper and lower fixture block is fixed by the connector of both sides, front and back respectively.
The upper and lower end of described upper and lower fixture block is respectively equipped with the contiguous block with hangers, the contiguous block hangers is fixed by screw and nut and connecting rod one end, the connecting rod other end is provided with vertical nut, the vertical nut of connecting rod links to each other with the telescopic lever of its TBE (threaded both ends) respectively in twos, with the rotation by telescopic lever, make vertical nut, connecting rod and upper and lower fixture block drive oil pipe and move axially.
The utlity model has following advantages and effect: adopt such scheme, can be easily by two oil pipe snap rings that consisted of by upper and lower fixture block, clamp respectively the oil pipe at Buchholz relay two ends, pass through again the rotation of the telescopic lever of two oil pipe snap rings of connection, can easily oil pipe be strutted to the Buchholz relay two ends, thereby dismounting Buchholz relay reposefully, and can not injure Buchholz relay and adpting flange, sealing ring between oil pipe and flange can precisely, be installed simultaneously with putting in place, avoid the fitting tight part to be shifted and the oil impregnate problem that causes.The utlity model has the characteristics such as simple in structure, easy to use, flexible operation, be not only applicable to the dismounting of transformer Buchholz relay, also be widely used in the dismounting of valve, attaching parts etc. on the various pipelines.
