Background technique
Contact box is used for various handcart switch cabinets, is a kind of insulating part, electric property to transformer and mechanically stable
Property plays an important role.In the use process of transformer, often since some factors physically or chemically lead to contact
There is aging in box.Firstly, transformer is power equipment, inside is filled with a large amount of electric power, and shelf depreciation is easy to produce ozone,
Ozone is a kind of very high substance of oxidisability, it is easy to cause insulator material to be cracked by ozone oxidation, here it is voltage ageings.
Secondly, there are also heat ageing, when operation, inside is easy to generate a large amount of heat transformer other than voltage ageing, from
And make insulating polymeric material that thermal degradation, low-molecular material generation or evolution occur, here it is common heat ageing, heat ageing can make
The insulation performance and mechanical performance of insulating materials are greatly reduced.Finally, being called environmental aging there are also a kind of aging, refer to insulation material
Pollution chemical reaction caused by expecting under the action of the factors such as light, oxygen, radiation and soda acid, and most significant of them is
Ultraviolet light in sunlight.
Summary of the invention
The technical problem to be solved by the present invention is in view of the deficiencies of the prior art, provide a kind of high pressure that can be anti-aging
Switch cabinet contact box, to enhance the service life of contact box.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is as follows:
A kind of contact box of high-voltage switch cabinet, including box body, busbar line outlet, static contact installation mold insert, busbar limit mold insert
And erecting bed, the box body include the first box body, the second box body and third box body being arranged successively from top to bottom, the first box
Busbar limit mold insert is fixed at the top of body, side is connected to busbar line outlet, and static contact installation mold insert is located at the first box body top
The connectivity part in portion and busbar line outlet；
The box body is made up of following parts by weight of component:
Wherein, using epoxy resin and polyurethane as basis material, 2,4-DihydroxyBenzophenone is added and stablizes as light
Agent, tin stabilizer is as heat stabilizer, and silica is as heat-resistant filler, and ethyl alcohol is as solvent and dispersing agent.
Further, the second box body longitudinal section is trapezoidal, and upper end opening is less than lower ending opening, and it is empty to be conducive to the intracorporal heat of box
Gas climbs.
Third box body longitudinal section be it is trapezoidal, upper end opening is greater than lower ending opening, and third box side wall is concave-convex alternate
Wave structure is convenient for heat extraction.
The bottom of the erecting bed is equipped with mounting hole and limit hole, and limit hole is shrinkage pool, is not connected to.
Further, the bottom of the busbar limit mold insert is fixed at the top of the first box body by stop collar, to reinforce
Busbar limits mold insert, prolongs its service life.
The utility model has the advantages that
Contact box of high-voltage switch cabinet structure of the present invention is simple, by the design of three box bodys, climbs convenient for the hot-air in box
And heat dissipation；The bottom of busbar limit mold insert is reinforced by adding stop collar, can effectively extend making for busbar limit mold insert
With service life and connective stability；Contact box box body is using epoxy resin and polyurethane as basis material, composite light stabilizer, heat
Stabilizer and heat-resistant filler keep the anti-aging property of box body significant.
Detailed description of the invention
The present invention is done with reference to the accompanying drawings and detailed description and is further illustrated, of the invention is above-mentioned
And/or otherwise advantage will become apparent.
Fig. 1 is the vertical section structure figure of the contact box of high-voltage switch cabinet；
