Abstract
The utility model relates to a generating line among high-voltage apparatus supports, insulating novel bus insulator. The technical scheme is as follows: the base body is in a buckled basin shape, the middle upper part of the base body is provided with an insulator, and a bus through hole is axially arranged along the center line of the insulator. And a raised sealing ring extends towards the axis direction from the inner wall of the bus through hole. The sealing ring is usually made of rubber materials, has good flexibility, and can meet the requirement that a bus with a certain diameter range keeps good centering and stability in a through hole, so that the field intensity distribution from the center to the edge of the surface of the insulator is uniform, and the reliability of insulation is improved.
Description
One, technical field: the utility model relates to the novel bus insulator that the bus in a kind of High-Voltage Electrical Appliances supports, insulate.
Two, background technology: in combined electrical apparatus, fixedly the disc insulator of bus and bus plug-in type contact must have secure support and insulation against ground level.The bus through hole of the bus disc insulator in the high pressure combined electrical apparatus itself does not have retractility before, fixedly makes troubles for the bus of different-diameter, makes insulator surface inhomogeneous by the extrorse field strength distribution in center, has influenced the reliability of insulation.
Three, summary of the invention: the purpose of this utility model is exactly the defective that exists at prior art, and a kind of novel bus insulator is provided.
Its technical scheme is: its matrix is the benzvalene form of detaining, and is provided with insulator in the middle and upper part of matrix, is axially arranged with the bus through hole along the center line of insulator.Described bus through-hole wall is extended with the sealing ring of projection to axis direction.
Sealing ring adopts elastomeric material to make usually, self has good retractility, it is good placed in the middle and stable that the bus that can satisfy the certain diameter scope keeps in through hole, thereby make insulator surface even by the extrorse field strength distribution in center, improved the reliability of insulation.
Four, description of drawings:
Accompanying drawing is a sectional structure chart of the present utility model.
Five, specific embodiment:
With reference to accompanying drawing, seeing on the profile with existing disc insulator has nothing basic identical, and its matrix 1 is the benzvalene form of detaining, and is provided with insulator 2 in the middle and upper part of matrix 1, is axially arranged with bus through hole 3 along the center line of insulator 2.Different is bus through hole 3 inwalls are extended with sealing ring 4 from projection to axis direction.Sealing ring adopts elastomeric material to make usually, self has good retractility, it is good placed in the middle and stable that the bus that can satisfy the certain diameter scope keeps in through hole, the situation analysis of insulating surface field strength distribution shows that the electric field strength potential difference of each point is little from inside to outside for the utility model provides under similarity condition insulator inside and outside contour surface, and insulating reliability is significantly improved.
