Abstract
The utility model relates to a bus insulating plate and belongs to the technical field of power distribution arrangement. The bus insulating plate comprises an insulating plate main body. The insulating plate main body is provided with an O-shaped through groove and the middle part of the lower end of the insulating plate main body is provided with a U-shaped through groove to make the front side of the insulating plate main body of a UO shape. Left and right sides of the insulating plate main body are symmetrically provided with sliding slots. The utility model has simple structure and reasonable design, adopts a UO-shaped track insertion method, and effectively solves the problems caused by the performance indexes such as resisting high temperature, resisting high voltage, resisting extrusion of the heavy pressure, and the like which cannot meet the requirements of the national standards. The adopted unsaturated polyester fiber glass material has large insulating resistance and strong high voltage resistance to effectively guarantee the insulation reliability among phases of a bus. A comparative tracking index value meets the national standards, thus, the bus insulating plate has no tracking. The bus insulating plate has high flexural strength and can guarantee that the bus does not crack under the condition of bearing a large pressure when arranging a fastening bolt so as to ensure the long-term normal operation of the bus.
Description
Technical field
The utility model belongs to the technical field that distribution is provided with, and is specifically related to a kind of bus insulation plate that distribution bus is installed that is used for.
Background technology
Bus in the existing low-voltage distribution apparatus generally is fixedly mounted on the framework by insulator, when the insulator of traditional structure is connected with bus, need punch on bus, uses bolt again, thereby equipment installation friendship trouble, and installation effectiveness is low.And the bus duct insulation board all selects for use the intoxicated asbestos of trimerization hydrogen first as material usually in the market, and the problem that this material exists is the pressure requirement that flexural strength does not satisfy the actual installation needs, make the bus butt joint time install that fastening dynamics does not reach requirement as yet and insulation board has ftractureed, cause electric clearance and creepage distance deficiency between alternate electrified body, cause phase fault.
The utility model content
At problems of the prior art, the purpose of this utility model is to provide the technical scheme of the good bus insulation plate of a kind of easy for installation, high temperature resistant, high voltage withstanding and anti-high pressure performance.
Described bus insulation plate is characterized in that comprising the insulation board main body, and O type groove is set on the insulation board main body, and middle part, insulation board main body lower end is provided with U type groove, makes insulation board main body front be the UO type, and insulation board main body side is symmetrical set chute.
Described bus insulation plate is characterized in that described insulation board main body adopts the unsaturated polyester glass fiber material to make.
Described bus insulation plate is characterized in that described insulation board main body side is wedge structure up and down.
The utility model is simple in structure, reasonable in design, adopt UO type rail mounted insertion, the performance index such as extruding that solved effectively owing to high temperature resistant, high voltage withstanding and anti-high pressure do not reach the problem that request of national standard causes, the unsaturated polyester glass fiber material insulation resistance that adopts is big, high voltage withstanding ability is strong, has effectively guaranteed each alternate insulating reliability of bus.The phase ratio creepage tracking index value satisfies national standard, no tracking.The flexural strength height can be guaranteed that bus bears under the situation of very big pressure not ftracture when fastening bolt is installed, guaranteed the long-term normal operation of bus.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the side-looking structural representation of Fig. 1.
Among the figure: 1-insulation board main body, 2-O type groove, 3-chute.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The bus insulation plate comprises insulation board main body 1, and O type groove 2 is set on the insulation board main body 1, and middle part, insulation board main body 1 lower end is provided with U type groove, makes insulation board main body 1 front be the UO type, and insulation board main body 2 sides are symmetrical set chute 3.When the bus insulation plate was installed, insulation board main body 1 front was the UO type, and side is symmetrical set chute 3, can directly adopt the rail mounted insertion, and is quick and easy for installation.Insulation board main body 1 adopts the unsaturated polyester glass fiber material to make, insulation board main body 1 side is wedge structure up and down, the performance index such as extruding that solved effectively owing to high temperature resistant, high voltage withstanding and anti-high pressure do not reach the problem that request of national standard causes, the unsaturated polyester glass fiber material insulation resistance that adopts is big, high voltage withstanding ability is strong, has effectively guaranteed each alternate insulating reliability of bus.The phase ratio creepage tracking index value satisfies national standard, no tracking.The flexural strength height can be guaranteed that bus bears under the situation of very big pressure not ftracture when fastening bolt is installed, guaranteed the long-term normal operation of bus.
