Description
Technical field
The utility model is related to field of track traffic, especially a kind of vacuum circuit-breaker insulated and vacuum circuit breaker.
Background technology
Insulator used in existing BVAC.N99 series and TDV10 series vacuum circuit breakers mostly uses greatly porcelain, silicon rubber
Material is connect with metal-ware, and volume and quality are larger, cannot be satisfied installation space narrow in interior or high-voltaghe compartment, and insulate
Ontology and metal-ware once occur the failures such as loosening, crack, and there are some potential safety problemss.It is analyzed from structure, existing vacuum
The insulator of breaker is split structure, is realized over the ground by two insulator right angle settings or the combining form being superimposed up and down
And electrode insulation occurs electric discharge phenomena, causes under vacuum circuit breaker performance frequently under moist or seriously polluted application environment
Drop.
Invention content
Technical problem to be solved in the utility model is, in view of the shortcomings of the prior art, it is exhausted to provide a kind of vacuum circuit breaker
Edge and vacuum circuit breaker improve the reliability of vacuum circuit breaker.
In order to solve the above technical problems, technical solution used by the utility model is：A kind of vacuum circuit-breaker insulated,
Including ontology；Described body by integral forming, and the first connector is set in the middle part of the ontology；The ontology top is equipped with the second connection
Part；Second connector outer surface is equipped with insulating layer.
First connector is connect for ontology with external equipment.
First connector, the second connector are respectively connected by lower metal insert, upper metal insert and the ontology
It connects.Metal insert is detachable, easy access and maintenance.
It is equipped with sealing ring between second connector and the ontology, dust-proof, waterproof action is played to internal cavity.
First connector is annular, plays the role of inside and presses, avoids point discharge.
The ontology is in pagoda-shaped from top to bottom, it is ensured that the stability of insulator center of gravity.
One, ontology top full skirt, two, middle part full skirt, the full skirt of bottom end one is ellipse, remaining full skirt is circle
Shape, the electric clearance and creepage distance between high voltage input terminal and output end, between output and ground had not only been increased, but also
Reduce insulator volume and weight.
First connector, the second connector are flange.
It is spiral formula structure that the body lower part, which divides inner cavity from bottom to top, and insulator inner cavity is from bottom to top helically
Ascending manner structure, the helical structure are distributed in insulator lower cavity, and insulator upper cavity is used to install vacuum bubbles, and absolutely
Gap silicon rubber filling between edge inner cavity and vacuum bubbles, played between vacuum bubbles shell and interior insulator isolation and
Cushioning effect, and the insulation performance of vacuum bubbles outer can be improved, avoid interior insulator discharge breakdown.
Ontology material is epoxy resin, solves the problems, such as that silicon rubber, porcelain insulator loosen, crack.
Correspondingly, the utility model additionally provides a kind of vacuum circuit breaker, uses above-mentioned insulator.
Compared with prior art, it is had the beneficial effect that possessed by the utility model：The utility model uses epoxy resin material
Expect integrally formed insulator, solves the problems, such as that silicon rubber, porcelain insulator loosen, crack；Insulator umbrella is ellipse,
Not only ensure good insulation performance, but also alleviated volume and quality, and be suitable for installation in roof and high-voltaghe compartment.
Description of the drawings
Fig. 1 is the utility model embodiment structural schematic diagram；
Fig. 2 is the sectional view along A-A of Fig. 1.
Specific implementation mode
As depicted in figs. 1 and 2, the utility model upper flange 2（That is the second connector 2）Material is copper, exposed surface and peace
Fill the processing of end face electrosilvering, it is ensured that the electric conductivity of well conducting.It is connected with screw between upper flange 2 and insulator body 5, it can
Dismounting, in order to overhaul and safeguard；There is sealing ring 3 between upper flange 2 and insulator body 5, internal cavity is played dust-proof, anti-
Water acts on；2 outside wrapping portion epoxy resin 1 of upper flange（That is insulating layer 1）Material, to improve insulation performance.
Upper metal insert 4,7 material of lower metal insert are stainless steel, are respectively used to upper flange 2 and insulator body 5, insulation
Connection between sub- ontology 5 and external equipment；Upper and lower metal insert is previously implanted in insulator body.
Intermediate embedded flange 6（That is the first connector 6）By copper material machine-shaping, intermediate embedded flange is designed as ring
Shape plays the role of inside and presses, avoids point discharge.Intermediate embedded flange 6 is previously implanted in insulator body.
Insulator body material is cycloaliphatic epoxy resin, is in pyramid-like structure from top to bottom, it is ensured that insulator center of gravity
Stability；In insulator umbrella design, up and down and intermediate four full skirts are ellipse, remaining full skirt is circle, is both increased
Electric clearance between high voltage input terminal and output end, between output and ground and creepage distance, but reduce volume and
Weight；Insulator inner cavity is that spiral formula structure, the helical structure are distributed in insulator lower cavity from bottom to top, is insulated
Sub- upper cavity is for installing vacuum bubbles, and the gap silicon rubber filling between insulator inner cavity and vacuum bubbles, to vacuum bubbles
Isolation and cushioning effect are played between shell and interior insulator, and can improve the insulation performance of vacuum bubbles outer, avoid insulating
Sub- internal discharge breakdown.
