Abstract
The utility model relates to high-voltage switch gear technical field, is specifically related to a kind of arc-extinguishing chamber of circuit breaker quiet side radome.It comprises cover body, and described cover body is the cylindrical housings with both ends open, and upper end open place is with arc transition place.The limit, one end of described cylindrical housings curves inwardly and forms arc transition place.The utility model is the shielding case structure of overall rotary extrusion type spinning, effectively improves the Electric Field Distribution of arc control device inside, absorbs a part of arc energy, condensation electric arc product.When arc control device cut-off short circuit current, the heat energy major part conductively-closed system that electric arc produces absorbed, and is conducive to improving the medium recovery strength between contact.Overall rotary extrusion type spinning radome is by rotating screw thread mounting means simultaneously, effectively avoid the problems such as the corner angle that mounting process and running may cause, thus the generation of the electric discharge preventing Potential distribution inequality from causing and insulation breakdown, ensure that power system safety and stability runs.
Description
Technical field
The utility model relates to high-voltage switch gear technical field, is specifically related to a kind of arc-extinguishing chamber of circuit breaker quiet side radome.
Background technology
Arc-extinguishing chamber of circuit breaker quiet side radome can prevent contact from arcing process, producing a large amount of metallic vapours and droplets, pollutes the inwall of insulation crust, avoids the dielectric strength causing arc control device shell decline or produce flashover.Improve the Electric Field Distribution of arc control device inside, absorb a part of arc energy, condensation electric arc product.Particularly arc control device are when cut-offfing short circuit current, and the heat energy major part conductively-closed system that electric arc produces absorbed, and is conducive to improving the medium recovery strength between contact.
Radome design in general arc-extinguishing chamber of circuit breaker quiet side is assembled by two parts, is easy to because mounting process problem produces dislocation and occurs corner angle, causing non-uniform electric thus, charge concentration and discharging, and insulation easily punctures.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of arc-extinguishing chamber of circuit breaker quiet side radome, adopt overall rotary extrusion type spinning structure, effective uniform electric field distribution, the electric field avoiding the problems such as the dislocation because mounting process causes and corner angle to produce is concentrated and electric discharge.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of arc-extinguishing chamber of circuit breaker quiet side radome, comprise cover body, cover body is the cylindrical housings with both ends open, and upper end open place is with arc transition place.
The limit, one end of described cylindrical housings curves inwardly and forms arc transition place.
Screw thread is provided with inside the described lower ending opening with the cylindrical housings of both ends open.
Described cover body is overall spinning structure, without seam.
Described cover body is made up of stainless steel material.
Be connected by the quiet side of screw thread and arc-extinguishing chamber of circuit breaker inside the described lower ending opening with the cylindrical housings of both ends open.
Advantage of the present utility model and beneficial effect are:
The utility model, by carrying out Curve guide impeller, the shielding case structure of overall rotary extrusion type spinning to the structure of arc-extinguishing chamber of circuit breaker quiet side radome, effectively improves the Electric Field Distribution of arc control device inside, absorbs a part of arc energy, condensation electric arc product.When arc control device cut-off short circuit current, the heat energy major part conductively-closed system that electric arc produces absorbed, and is conducive to improving the medium recovery strength between contact.Simultaneously by the change of mounting means, overall rotary extrusion type spinning radome is by rotating screw thread mounting means, effectively avoid the problems such as the corner angle that mounting process and running may cause, thus the generation of the electric discharge preventing Potential distribution inequality from causing and insulation breakdown, ensure that power system safety and stability runs.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that in-site installation of the present utility model uses schematic diagram.
In figure: cover body 1, arc transition place 2, lower ending opening 3, radome 4, fixed contact 5, moving contact 6, Capacitor banks 7, supporting insulator 8.
Embodiment
The utility model is a kind of arc-extinguishing chamber of circuit breaker quiet side radome, as shown in Figure 1, formed primarily of cover body.Cover body 1 is for having the cylindrical housings of both ends open, and radome is overall spinning structure, without seam.Wherein, upper end open place is with arc transition place 2, and be curved inwardly by the limit, one end of this cylindrical housings to form arc transition, the transition angle at this arc transition place 2 is larger.Being provided with screw thread inside the lower ending opening 3 with the cylindrical housings of both ends open, being fixed on arc-extinguishing chamber of circuit breaker fixed contact side by rotating screw thread.Described cover body 1 is made up of stainless steel material.
As shown in Figure 2, each electric elements of circuit breaker mainly comprise fixed contact 5, moving contact 6, Capacitor banks 7 and supporting insulator 8.During concrete enforcement, radome 4 described in the utility model is connected with the quiet side of arc-extinguishing chamber of circuit breaker fixed contact 5 side is firm by the inside thread with the lower ending opening 3 of the cylindrical housings of both ends open, outside the phase post being namely fastened on each electric elements.
Above-mentioned embodiment is preferred embodiment of the present utility model; can not limit the utility model; concrete execution mode can be determined according to the technical solution of the utility model and actual conditions; other any substitute mode for deviating from change that the technical solution of the utility model makes or other equivalence, is included within protection range of the present utility model.
