Abstract
The invention discloses a porcelain shell combination structure for a vacuum arc-extinguishing chamber. The porcelain shell combination structure comprises a porcelain shell (1) and a shielding tube (2) and is characterized in that the shielding tube (2) is fixed in the porcelain shell (1) through a spring clamp (3). The porcelain shell combination structure is pushed into the porcelain shell through a stainless steel spring clamp welded on the shielding tube, and a boss in the porcelain shell is clamped by utilizing the principle of the spring clamp, so that the shielding tube is fixed in the porcelain shell. The two ends of the spring clamp have the extending angles of 15 to 20 degrees; when the fixed position at the middle part of the porcelain shell is in a maximum size, the shielding tube can be clamped; and when the fixed position at the middle part of the porcelain shell is in a minimum size, the spring clamp extends after being stressed. The porcelain shell is welded in a furnace at one time instead of being welded into a component independently and then being welded in the furnace again. The porcelain shell is easy to operate; the production efficiency is improved; evaporation pollution and man-made pollution caused by welding the porcelain shell, the shielding tube and the spring clamp in the furnace twice are reduced; the insulation performance of a product is improved; the cost is reduced; and energy resource is reduced.
Description
Technical field
The invention belongs to a kind of vacuum arc-extinction porcelain shell combining structure, relate to the vacuum switch tube technical field.
Background technology
Existing combined structure of ceramic case is first retainer ring and shielding cylinder to be advanced stove to be welded into the shielding cylinder combiner, advance stove by retainer ring transition and insulation porcelain shell and other assembling parts together with more again and carry out secondary welding, due to the restriction that is subjected to porcelain shell dimensional tolerance, the product axiality is difficult for guaranteeing.It is large that the parts secondary advances stove power consumption, and secondary advances heat size and easily cause evaporative emission, affects the product insulation property.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of Novel vacuum interrupter porcelain shell combined structure, a welding fabrication, and energy savings, avoided secondary pollution, guaranteed the axiality of product, improved reliability and the insulating properties of product.Simultaneously, in the middle of the porcelain shell, fixed mask cylinder place need not metallize, few one technological process.
Technical scheme of the present invention: the vacuum arc-extinction porcelain shell combining structure, comprise porcelain shell and shielding cylinder, described shielding cylinder is fixed in the porcelain shell by the shell fragment clamp.
Aforesaid vacuum arc-extinction porcelain shell combining structure, described shell fragment clamp adopts more than 3, and shell fragment clamp one end is welded on shielding cylinder.
Aforesaid vacuum arc-extinction porcelain shell combining structure, described shell fragment clamp two ends are provided with for 45 ° of fixing bendings, and bending is stuck on the boss of porcelain shell inwall.
Aforesaid vacuum arc-extinction porcelain shell combining structure, described shell fragment clamp is provided with curved the analysing more than 2 times, is provided with the extension bending of 15 °～20 ° of gradients at shell fragment clamp two ends.
Beneficial effect: compared with prior art, the present invention has following features:
The stainless steel shell fragment clamp of this vacuum arc-extinction porcelain shell combining structure by welding on shielding cylinder, be advanced in the porcelain shell, utilizes shell fragment clamp principle that porcelain shell inner convex platform is blocked, and shielding cylinder is fixed in the porcelain shell.15 °～20 ° of shell fragment clamp two ends is to extend angle, can block shielding cylinder when porcelain shell middle part bearing full-size, when porcelain shell middle part bearing is minimum dimension, and the stressed rear extension of shell fragment clamp.The porcelain shell need not first be welded into separately after parts secondary again and advance the stove welding, but once advance the stove welding, operate simple and easy, improved production efficiency, reduce porcelain shell and shielding cylinder and spring clip secondary and advanced evaporative emission and the artificial pollution that the stove welding causes, improve the insulation property of product, reduced cost, saved the energy.

Embodiment
Embodiment 1.As shown in Figure 1 and Figure 2, shell fragment clamp 3 on useful laser welding on shielding cylinder 2, shell fragment clamp 3 intermediate fabrication go out less bending, be used for fixing, produce the bending 5 of 45 ° at shell fragment clamp 3 two ends, shielding cylinder 2 is advanced in porcelain shell 1, porcelain shell 1 inner convex platform 4 is expressed to the middle part of shell fragment clamp 3, utilize 45 ° of shell fragment clamp 3 bendings 5 and plane to be stuck in shielding cylinder 2 and porcelain shell 1, thereby realize that product parts once advances the stove welding.Produce curved analysing more than 2 times at shell fragment clamp 3, produce the extension bending 6 of 15 °～20 ° of gradients at shell fragment clamp 3 two ends, fixed effect is better.Can block shielding cylinder 2 when porcelain shell 1 middle part bearing full-size, when porcelain shell 1 middle part bearing was minimum dimension, the stressed rear extension of shell fragment clamp 3, regulated the deformation of shell fragment clamp 3.
The above, it is only preferred embodiment of the present invention, not the present invention is done any pro forma restriction, any technical solution of the present invention content that do not break away from,, all still belong in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does according to technical spirit of the present invention.
