Abstract
The utility model relates to a gas buffer, which is used for a load switch unit that uses compressed gas as arc-extinguishing medium. The characteristics are as follows: the arc generated by a load switch during break-brake is extinguished by the compressed gas generated by a moving contact during downward running, and the impact force generated by the moving contact during downward running is related to the service life and the mechanical strength of the load switch; the impact force on the bottom in the moving contact moving process can be greatly reduced through the gas buffer provided by the utility model, and the energy of the impact force can be basically reduced to zero when closing to the bottom. The gas buffer is safe and reliable.
Description
Affiliated technical field
The utility model relates to the gas cushion of the pressured gas arc extinguishing that contracts in a kind of high voltage switchgear, belongs to the high voltage power transmission and transforming field.
Background technology
Along with China's power transmission and transforming equipment in modern age is updated, in the existing high voltage switchgear, the on-load switch of the pressured gas arc extinguishing that contracts, on-load switch is when separating brake, because the downward rapid movement of moving contact can produce bigger impulsive force, if this impulsive force can not be slackened near 0, will inevitably cause very big impulsive force to the moving contact bottom, intensity reduces, the shortening in useful life.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, new gas buffer device that can prolong load switching unit useful life to slacken the problem to 0 to solve the impulsive force that produces during the moving contact separating brake that can not make of the prior art.
The technical solution of the utility model is achieved in that and will adds a tower spring in the gas cushion, the impulsive force that moves downward during accurate Calculation on-load switch separating brake, make it when the compression spring, be subjected to the obstruction of power, after moving to end, impulsive force just slackens 0, thereby has improved the useful life of product.
The beneficial effects of the utility model are:
Cellular construction of the present utility model is simple, invest little, the useful life of having improved on-load switch.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is the theory structure schematic diagram of gas cushion of the present utility model
Among the figure
1 piston is led end, 2 guiders, 3 cylinder bodies, 4 pillars, 5 displacers, 6 tower springs, 7 bases
Embodiment
Below, describe preferred embodiment of the present utility model in detail with reference to accompanying drawing.Need to prove before this, employed term or word can not limited interpretation be common implication or the implication in the dictionary in this specification and claims book, and should be based in order to illustrate that in the best way principle that its practical novel inventor can suitably define the notion of term is interpreted as meeting the implication and the notion of the utility model technological thought.Thereupon, the structure of representing in embodiment that this specification is put down in writing and the accompanying drawing is one of the utility model most preferred embodiment, can not represent technological thought of the present utility model fully, therefore should be understood that for the utility model, to have various equivalents and the variation that to replace.
As shown in Figure 1, the utility model gas cushion is led end (1), guider (2), cylinder body (3), pillar (4), displacer (5), tower spring (6), base critical pieces such as (7) by piston and is formed.
Described this gas cushion is used for a kind of with the load switching unit of Compressed Gas as arc-extinguishing medium, displacer (5) moves downward, the impulsive force that motion produces, cancel out each other with the reaction force that tower spring (6) produces, make base (7) be subjected to less than active force, thus the life-span of having improved product.
Tower spring (6) is a truncated conical shape in described this gas cushion, makes spring in the process of being compressed, the held stationary state, and can not depart from contact between the base (7).
Claims (1)
1. gas cushion, comprise by piston and lead a kind of new gas buffer that end (1), guider (2), cylinder body (3), pillar (4), displacer (5), tower spring (6), base (7) are formed, it is characterized in that, tower spring (6) is arranged at the lower end of displacer (5), the impulsive force that after displacer (5) moves downward, produces, the reaction force that produces after can being compressed with tower spring (6) is cancelled out each other, and described tower spring (6) is a truncated conical shape.
