Abstract
The utility model relates to an insulation pull rod of the high pressure breaker, which is composed of an outer insert, an inner insert, and an insulation pipe, the end of which is arranged between the outer and inner inserts; a plurality of grooves are arranged on the inner surface of the outer insert and the outer surface of the inner insert, the inner and outer surfaces of the insulation pipe matching with the outer and inner insert is a processed rough surface, an adhesive dose is filled in the fitting clearance between the insulation pipe and the outer insert and between the insulation pipe and the inner insert. The structure improves the adhesive intensity of the interface; by test, the pulling resistance intensity of the insulation pull rod is larger than 220kN.
Description
Technical field
The utility model belongs to the parts on the primary cut-out, relates in particular to the insulated tension pole on the primary cut-out.
Background technology
Insulated tension pole is the vitals of circuit breaker, and to the very high requirement that has of its electric property and mechanical performance, the quality of insulated tension pole quality directly has influence on the reliability of circuit breaker and the safe operation of electrical network; So, it much is to adopt external insulated tension pole that circuit breaker product in the 252kV gas-insulated gas insulated metal enclosed swit chgear (GIS) of domestic production has, but, because the circuit breaker and the external product of domestic production are different, the operating work that home products needs is very big, usually more than 210kN, the intensity of import pull bar generally is lower than 180kN, in pull test, joint when pulling force reaches 180kN in the insulated tension pole and insulated tube will come off, and the specification requirement that hot strength can't reach product design also often appears in the therefore external insulated tension pole of producing.
Summary of the invention
The purpose of this utility model is: the insulated tension pole that provides a kind of circuit breaker product tension intensity that can satisfy domestic production to require, the tensile strength of this insulated tension pole is more than or equal to 210kN.
The purpose of this utility model realizes by following scheme: this insulated tension pole that is used for primary cut-out, comprise externally inlaid part, embedded component and the end insulated tube between externally inlaid part and embedded component, the inner surface of externally inlaid part and the outer surface of embedded component are provided with many grooves, and the degree of depth of groove is 0.3mm～0.7mm; The surfaces externally and internally of the insulated tube of the part that matches with externally inlaid part and embedded component is the coarse surface of processing, and surface roughness Ra is 12.5-50 μ m, is filled with bonding agent between insulated tube and the externally inlaid part and in the fit clearance between insulated tube and the embedded component.
Many grooves of the outer surface setting of the inner surface of described externally inlaid part and embedded component are the V-type groove, and they are parallel to each other, and the degree of depth of V-type groove is 0.4mm-0.5mm.
Described insulated tube and externally inlaid part and embedded component fit clearance are 0.1mm～0.3mm.
Described insulated tube and externally inlaid part and embedded component fit clearance are 0.2mm.
Described bonding agent is an epoxide-resin glue.
The inner surface of the externally inlaid part of this insulated tension pole that is used for primary cut-out and the outer surface of embedded component are provided with many grooves, and the surfaces externally and internally of the insulated tube of the part that matches with externally inlaid part and embedded component is the coarse surface of processing, in their fit clearances, be filled with bonding agent again, therefore improved adhesive effect, the utility model has been selected preferable fit clearance for use in addition, has further improved the adhesive strength of joint; After tested, the insulated tension pole tensile strength in the utility model adopts our self-produced product greater than 220kN, has saved enterprise originally from the spending of foreign procurement, has reduced the cost of primary cut-out product.
