Abstract
The utility model discloses a vacuum interrupter protective structure, there is the upper and lower mount pad of circuit breaker housing body one side including fixed mounting, installs vacuum interrupter between the upper and lower mount pad, the upper and lower support of fixedly connected with respectively on the upper and lower mount pad have upper and lower stand, the internal diameter of going up the stand is less than the internal diameter of stand down, and the rear end of upper and lower stand is rotated respectively and is connected with upper and lower mount pad, corresponds to be connected with the spring front end of the front end suit of last stand under between upper and lower support and the upper and lower mount pad respectively. The utility model discloses simple structure constitutes vacuum interrupter's outer protective structure through nested upper and lower stand together, and play that protection vacuum interrupter avoids strong exogenic action and the spring when needs are maintained or are changed vacuum interrupter, only need be extrudeed to the effect that damages, the upper and lower stand that outwards turns, relieve the two nested within each other can, it is very convenient to operate.
Description
Technical field
The utility model relates to vacuum interrupter field, specifically a kind of vacuum interrupter safeguard structure.
Background technology
Vacuum interrupter, have another name called vacuum switch tube, it is the core component of mesohigh power switch, its Main Function is, by can blow-out suppress electric current rapidly after managing the excellent insulating properties of interior vacuum and making mesohigh circuitry cuts power supply, avoid accident and unexpected generation, be mainly used in the power transmission and distribution control system of electric power, be also applied to the distribution systems such as metallurgy, mine, oil, chemical industry, railway, broadcast, communication, industrial high-frequency heating.There is energy-conservation, material-saving, fire prevention, explosion-proof, volume is little, the life-span is long, maintenance cost is low, the feature such as reliable and pollution-free.
Vacuum interrupter is divided into again arc extinguishing chamber for breaker and on-load switch arc control device purposes, and arc-extinguishing chamber of circuit breaker is mainly used in transformer station in power department and electrical network facilities, and on-load switch arc control device are mainly used in the terminal use of electrical network.
The glass tube of vacuum extinction outdoor or earthenware are comparatively fragile, if run into stronger External Force Acting, are easy to break, cause vacuum interrupter to be damaged.
Utility model content
The purpose of this utility model be in order to overcome prior art exist defect and deficiency, a kind of vacuum interrupter safeguard structure is provided.
The technical solution of the utility model is as follows:
A kind of vacuum interrupter safeguard structure, include and be installed with the upper of case for circuit breaker body side, lower mount pad, described is upper, between lower mount pad, vacuum interrupter is installed, it is characterized in that: on described, lower mount pad is fixedly connected with respectively, undersetting, include, lower pillar stand, the internal diameter of described upper pillar stand is less than the internal diameter of described lower pillar stand, on, the rear end of lower pillar stand is rotatably connected to respectively, lower mount pad, described is upper, undersetting and upper, spring has been connected respectively between lower mount pad, the front end sleeve of described upper pillar stand is contained in the front end of described lower pillar stand.
Described vacuum interrupter safeguard structure, is characterized in that: described upper and lower column adopts plastic conduit respectively.
The beneficial effects of the utility model:
The utility model structure is simple; the outer safeguard structure of vacuum interrupter is formed by the upper and lower column nested together; play the effect that protection vacuum interrupter damages from stronger External Force Acting; when needs are safeguarded or change vacuum interrupter; only need extrusion spring; outwards stir upper and lower column, both releasings mutually nested, operation is very easy.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
See Fig. 1, a kind of vacuum interrupter safeguard structure, include and be installed with the upper of case for circuit breaker body 1 side, lower mount pad 2, 3, on, lower mount pad 2, vacuum interrupter 4 is installed between 3, on, lower mount pad 2, be fixedly connected with respectively on 3, undersetting 5, 6, include, lower pillar stand 7, 8, the internal diameter of upper pillar stand 7 is less than the internal diameter of lower pillar stand 8, on, lower pillar stand 7, the rear end of 8 is rotatably connected to respectively, lower mount pad 9, 10, on, undersetting 5, 6 with upper, lower mount pad 9, spring 11 has been connected respectively between 10, the front end sleeve of upper pillar stand 7 is contained in the front end of lower pillar stand 8.
In the utility model, upper and lower column 7,8 adopts plastic conduit respectively.
Claims (2)
