Description
Technical field
The present invention relates to technical field of electric equipment, specifically, being a kind of mating insulated pull rod of indoor vacuum circuit breaker.
Background technique
Insulator is a kind of special insulation control, can be played an important role in overhead transmission lines.It is propped up between one's early years
Column insulator is chiefly used in electric pole, and the one end for being slowly developed in high type high-tension bus-bar connection tower has hung the insulator of many outstanding shapes,
It is usually made of silica gel or ceramics to increase creepage distance, and insulator is just.Insulator is in overhead transmission lines
Two basic roles are played, i.e., the two effects must be guaranteed support conducting wire, and insulator should not with returning with electric current is prevented
The various electromechanical stress caused by environment and electric load condition change and fail, otherwise insulator would not generate great
Effect, the use and service life of whole route will be damaged.
Currently, domestic electrical main circuit breaker of railway engine arc-chutes insulator is all high tension insulator material, the base in insulation performance
Originally needs be can satisfy, however all there are problems that causing arc-chutes insulator to burst due to temperature change in various regions, especially
The area such as northeast, North China, northwest is even more to reflect seriously, seriously affects safety of railway traffic.
Summary of the invention
To solve prior art problem, the present invention provides a kind of mating insulated pull rods of indoor vacuum circuit breaker.
The specific technical solution that the present invention uses is as follows：
A kind of mating insulated pull rod of indoor vacuum circuit breaker, the insulated pull rod is whole in tubular construction, the both ends of the tubular structure
Lateral surface is provided with the umbrella skirt construction of stacking, and two surfaces of umbrella skirt construction are in symmetrical circular conical surface, and edge is arc, tubular structure
Outer surface be covered with organic insulating material.
Further improvement of the present invention, the insulated pull rod use epoxide resin vacuum pouring one-step forming.
Further improvement of the present invention, the both ends of tubular structure are additionally provided with extended segment, round peace are provided on extended segment
Fill hole.
Further improvement of the present invention, the length ratio of the umbrella skirt construction of the middle section and both ends of tubular structure are 2:1.
Further improvement of the present invention, the length of tubular structure are 160-220mm, and the length of extended segment is 20-30mm.
Further improvement of the present invention, the internal diameter of tubular structure are 20-30mm, and the diameter of circular mounting hole is 2-6.5mm.
Beneficial effects of the present invention：The present invention uses epoxide resin vacuum pouring one-step forming, and surface is smooth, does not beat
Mill, does not repair, does not paint, bright-colored, and pressure-resistant insulation performance is high, and partial discharge quantity is small, bending strength, and creepage distance all accords with
Standardization requirement, can normal use under the conditions of condensation filth.
