Abstract
The utility model discloses a miniaturized vacuum interrupter, including moving conducting rod, uide bushing, going up the seal ring, porcelain ring, bellows, covering and closing the cover, moving contact, static current conducting plate, screw rod, porcelain ring and last seal ring, cover and close the cover and be connected, go up the seal ring and be connected with uide bushing, bellows, cover and close the cover and be connected with bellows, static current conducting plate, move the conducting rod and be connected with moving contact, bellows, the uide bushing is located moves the conducting rod outside, the static contact is connected with static current conducting plate, static current conducting plate is connected with the screw rod. On the premise of ensuring the electrical service life of the vacuum arc-extinguishing chamber, the heights of a corrugated pipe, a movable conducting rod and the like of the vacuum arc-extinguishing chamber are reduced, so that the height of the vacuum arc-extinguishing chamber is only 34mm, the vacuum arc-extinguishing chamber is applied to an on-load tap changer, the height of the on-load tap changer is reduced, the height of the on-load tap changer is not required to be increased when the vacuum arc-extinguishing chamber is installed in a distribution transformer, and the production cost of.
Description
Technical Field
The device relates to the technical field of electric power products, in particular to a miniaturized vacuum arc-extinguishing chamber for an on-load tap changer.
Background
With the integral development of domestic industrial technology, the switch gradually tends to be highly reliable and miniaturized. Although the volume of the vacuum arc-extinguishing chamber is continuously reduced, the volume of the vacuum arc-extinguishing chamber applied to the on-load tap changer in the existing market is relatively large, so that the volume of the on-load tap changer is large, and in order to reduce the volume (especially the height) of the on-load tap changer and further enable the on-load tap changer to be installed in a transformer, the volume of the transformer does not need to be increased, and the demand of the vacuum arc-extinguishing chamber is required to be met by a more miniaturized.
Disclosure of Invention
The utility model aims at providing a miniaturized vacuum interrupter, its appearance size is little, especially its high greatly reduced, and its superior performance, has solved among the prior art because of the bulky loaded tap changer volume problem of influence of vacuum interrupter.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a miniaturized vacuum arc-extinguishing chamber comprises a movable conducting rod, a guide sleeve, an upper sealing ring, a porcelain ring, a corrugated pipe, a shielding cover, a movable contact, a static conducting plate and a screw rod.
According to the utility model discloses a preferred embodiment, the distance of going up seal ring extremely static conductive plate is 34mm, promptly miniaturized vacuum interrupter's height is 34 mm.
Compared with the prior art, the beneficial effects of the utility model are that under the electric life prerequisite of ensureing vacuum interrupter, reduce vacuum interrupter's bellows, move the height of conducting rod etc for vacuum interrupter's height only is 34mm, uses on-load tap changer, reduces on-load tap changer's height, makes its height that does not need to increase distribution transformer of installing in distribution transformer, reduces on-load tap changer's manufacturing cost.

fig. 2 is an internal structure schematic diagram of a miniaturized vacuum interrupter of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings. The embodiments described below are merely intended to more clearly illustrate the technical solutions of the present invention, are selected embodiments of the present invention, and are not all embodiments, and therefore the scope of the present invention should not be limited thereto. All other embodiments obtained by a person skilled in the art without making any inventive step are within the scope of protection of the present invention.
Referring to fig. 1 and 2, a miniaturized vacuum arc-extinguishing chamber comprises a movable conducting rod 1, a guide sleeve 2, an upper sealing ring 3, a ceramic ring 4, a corrugated pipe 5, a shielding cover 6, a movable contact 7, a static contact 8, a static conducting plate 9 and a screw rod 10, wherein the ceramic ring 4 is connected with the upper sealing ring 3 and the shielding cover 6, the upper sealing ring 3 is connected with the guide sleeve 2 and the corrugated pipe 5, the shielding cover 6 is connected with the corrugated pipe 5 and the static conducting plate 9, the movable conducting rod 1 is connected with the movable contact 7 and the corrugated pipe 5, the guide sleeve 2 is positioned on the outer side of the movable conducting rod 1, the static contact 8 is connected with the static conducting plate 9, and the static conducting plate 9 is connected with the screw.
The design height of the miniaturized vacuum arc-extinguishing chamber is only 34mm, the height of the miniaturized vacuum arc-extinguishing chamber is greatly reduced compared with that of a conventional vacuum arc-extinguishing chamber, the miniaturized vacuum arc-extinguishing chamber is installed on an on-load tap changer, the height of the miniaturized vacuum arc-extinguishing chamber is reduced, and then the production cost of a distribution transformer increased due to the height of the on-load tap changer is reduced.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of changes and improvements can be made without departing from the technical principle of the present invention, and these changes and improvements should also be considered as the protection scope of the present invention.
