Abstract
The utility model relates to the technical field of arrester testing and discloses a general testing tool for proportional units of 35kV-and-above arresters with composite or ceramic sleeves. The general testing tool comprises an upper gland, an upper flange, a main insulation cylinder, a lower flange and a lower gland, wherein the upper gland and the upper flange are fixedly connected through a screw rod, the lower flange and the lower gland are fixedly connected through a screw rod, the upper end and the lower end of the main insulation cylinder are provided with external threads, and the upper flange and the lower flange are screwed and locked at the upper end and the lower end of the main insulation cylinder respectively. The general testing tool is applicable to most of the prior 35kV-and-above arresters with composite or ceramic sleeves, a proportional unit does not need to be customized for each tested product, the manufacturing cost is reduced to the greatest extent, and unnecessary waste is reduced; the flanges and a cover plate are made of high-strength metal, the general testing tool can be assembled only by opening the cover plate and is suitable for long-term use; and the general testing tool is easy to assemble, components are high in strength and easy to process, and the general testing tool can be reused for many times.
Description
Technical field
The utility model belongs to lightning arrester experimental technique field; Relate to the general test frock of a kind of 35kV and above composite sheath or porcelain coat lightning arrester ratio unit.
Background technology
At present, according to the IEC60099-4:2006(international standard) requirement of " interchange gapless metal-oxide lighting arrester " and China standard GB11032-2010 " interchange gapless metal-oxide lighting arrester ", tests such as operating duty in the lightning arrester type approval test must be carried out on section of an arrester, require section of an arrester must have the performance characteristic identical or harsher with whole lightning arrester and comprise their heat dissipation characteristics, electrical specification and internal atmosphere etc.
Because zinc oxide resistance sheet is sealed in the lightning arrester overcoat, must make by certain principle and have the equivalence section of an arrester, and before test the hot equivalence of checking section of an arrester and whole lightning arrester, and then carry out the test of the examination zinc oxide resistance sheet thermal characteristics stipulated in the type approval test, really test evaluation go out the energy absorption capability of whole lightning arrester, otherwise test and test findings will not have in all senses.
Yet the section of an arrester of producing the conformance with standard requirement has certain difficulty.The lightning arrester construction profile of each manufacturer and the internal resistance sheet property of there are differences need the different ratio unit of custom-made, even need die sinking to make, expense height not only, and can not guarantee to meet hot equivalence requirement, repeated multiple times possibly.Underproof and the test after the ratio unit just scrapped, cause great waste.
The utility model content
The purpose of this utility model is to provide 35kV and the general test frock of above composite sheath or porcelain coat lightning arrester ratio unit, to solve the problems of the technologies described above.
To achieve these goals, the utility model adopts following technical scheme:
The general test frock of a kind of 35kV and above composite sheath or porcelain coat lightning arrester ratio unit comprises upper press cover, upper flange, major insulation tube, lower flange and lower cover; Upper press cover is fixedlyed connected by screw rod with upper flange, and lower flange is fixedlyed connected by screw rod with lower cover; The top and bottom of major insulation tube are equipped with external thread, and upper flange and lower flange difference screw lock are in the top and bottom of major insulation tube.
The utility model further improves and is: be provided with first O-ring seal between upper press cover and the upper flange; Be provided with second O-ring seal between lower flange and the lower cover.
The utility model further improves and is: be provided with interior insulating cylinder in the major insulation tube.
The utility model further improves and is: upper press cover is provided with some first heat radiations and adjusts the hole; Lower cover is provided with some second heat radiations and adjusts the hole.
The utility model further improves and is: described some first heat radiations are adjusted and some or all ofly in the holes are sealed by screw; Described some second heat radiations are adjusted and some or all ofly in the hole to be sealed by screw.
The utility model further improves and is: described major insulation tube is that epoxy fibreglass twines insulation tube.
Compared with prior art, the utility model beneficial effect is:
1. economy.Be suitable for present most 35kV and above composite sheath or porcelain coat lightning arrester, need not to send trial product custom-made ratio unit at every kind again, farthest reduced and manufactured cost, reduced unnecessary waste.
2. property easy to use.Censorship manufacturer only need provide the resistor disc identical with the inner institute of lightning arrester dress resistor disc specification can carry out correlation test.
3. long-life property.Flange and cover plate adopt high duty metal, only need open cover plate during assembling, are fit to long-term the use.
4. reusability.The design is easy to assembling, and strength of parts is high and be easy to processing, can be repeatedly used.
5. high universalizable.No matter lightning arrester is a composite sheath, or the porcelain overcoat, all can adopt this test frock; Not limited by lightning arrester internal resistance sheet specification; By adjusting measures such as louvre, interior insulating cylinder, liner thermal insulation material, can satisfy requirement with whole the hot equivalence of lightning arrester.

Fig. 1 is a frock synoptic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
See also shown in Figure 1, the general test frock of the utility model 35kV and above composite sheath or porcelain coat lightning arrester ratio unit comprises upper press cover 2, first O-ring seal 3, upper flange 4, interior insulating cylinder 5, major insulation tube 6, lower flange 7, second O-ring seal 8 and lower cover 9.
Major insulation tube 6 top and bottom are equipped with external thread, and upper flange 4 and lower flange 7 difference screw locks are in the top and bottom of major insulation tube 6.Interior insulating cylinder 5 is arranged in the major insulation tube 6, under the slightly little situation of resistor disc, in the insulating cylinder 5, then interior insulating cylinder 5 is put into major insulation tube 6 in putting it into.
This frock according to the resistor disc full-size design inner chamber of present 35kV and above whole composite sheath or porcelain coat lightning arrester inside, and leaves certain nargin with reference to the architectural feature of domestic and international 35kV and above whole composite sheath or porcelain coat lightning arrester.The outer epoxy fibreglass that adopts twines major insulation tube 6, solved dielectric voltage withstand problem (outer composite sheath or the porcelain overcoat of adopting of lightning arrester, mainly be to solve resistant and Insulation Problems, and the ratio unit is only tested under indoor environment, so can not consider the resistant problem).For increasing durability and property easy to use, two ends, major insulation tube 6 top are with metal flange and metal cover board.Metal flange is connected by screw rod with metal cover board, is furnished with heat radiation on the metal cover board and adjusts the hole.
