上することを目的とする。This type of vacuum pulp shield is designed to prevent particles generated from the contacts and the contacts between them during the opening/closing process from rebounding. It is supported by either a ring or a wire lattice. It also additionally includes a molecular sieve material combined with a cooling cylinder that dissipates the energy absorbed by this type of shielding device - the invention improves heat dissipation from the shield surrounding the contact. The purpose of this invention is to improve the breaking ability of vacuum pulp for circuit breakers.

金属がら成る真空パルプと組合せると特に有利である。This object is achieved in the Shin-9 pulp of the above-mentioned type according to the invention in that the shield is at least locally joined by a surface to the cylindrical part of the container. This method of attaching the shield is different from the conventional method of fixing the shield, in that heat is conducted to the cylindrical part of the vacuum pulp through the thin fixed part of the shield. The structure of the shield based on this invention is It is particularly advantageous in combination with vacuum pulp, the cylindrical part of which consists of metal.

接による結合により蒔られる。It is best to form a shield by attaching a wave mold-like 0. Such a shield can be easily made on flat ice,
After that, it is possible to bend it into a circle and match it with the diameter C of the cylindrical part. Good heat conduction can be obtained simply by press-fitting the bending shield into the cylindrical portion kc. Even better values are achieved by brazing or welding connections.

た考慮される。Both contacts 6.7 are surrounded by a shield 12 which is constructed in a pleated manner like a bellows; the shield 12 therefore has a relatively large surface area and a correspondingly large heat absorption - By matching the outer diameter of the pleats to the inner diameter of the cylindrical portion 3, each pleat portion comes into contact with the cylindrical portion. The desired good fuel transmission is achieved by the mutual interference between the t-shield and the cylindrical part. In addition, for example metal-ceramic bonding by brazing between the two is also conceivable.

The selection is such that any particles or metal vapors generated or gases that are accidentally released are not bounced back into the intercontact space but are retained between the folds. , the depth of the pleats is about 10% of the diameter of the cylindrical part n. Further, the pleats are formed such that the surfaces arranged in the radial direction of the inner folds are parallel to each other and face each other. Alternatively, the selection of the radial depth and shape of the corrugations can be varied to suit the requirements placed on the shield. Additionally, the shield can be provided with holes or roughened surfaces to further reduce splashback or increase heat retention. The outer periphery of the pleats can also be connected, for example by brazing or spot welding or similar means, in such a way that the cylindrical part can reach υ at least in places.
