Abstract
The utility model discloses an outdoor high-voltage drop-out fuse. The outdoor high-voltage drop-out fuse is mainly provided with a fusion tube and an insulator, wherein the fusion tube is electrically connected with the upper end of the insulator through a movable contact and electrically connected with the lower end of the insulator through a fixed contact; a pull ring is arranged on the movable contact; one end of the fixed contact is hinged on the fusion tube, and the other end of the fixed contact is a connecting terminal fixedly connected with the lower end of the insulator; a disconnector and a fusion tube enhanced connecting sleeve are arranged at the lower end of the fusion tube; a disconnection component capable of enabling the fixed contact and the disconnector to be separated is arranged on the disconnector; a protecting cover is arranged on the movable contact; and the disconnection component is an alloy fusion piece arranged between the disconnector and the fixed contact. The outdoor high-voltage drop-out fuse has a simple structure, does not damage equipment, is safe and reliable, is convenient to mount and dismount, and has small contact resistance and high electric conductivity; the ceramic insulator has low probability of breakage due to high strength, and has a smooth surface and strong self-cleaning performance; the service life is long, the drop-out capacity is high, and repeated drop-out can be realized without the need of replacement; and the outdoor high-voltage drop-out fuse has the characteristics of ageing resistance and corrosion resistance.
Description
Technical field
The utility model relates to a kind of electric prospection equipment, relates in particular to a kind of outdoor high-voltage drop type fuse.
Background technology
Fuse switch is the most frequently used a kind of protective switch of the short circuit of 10kV distribution line branch line and distribution transformer; It has economy, easy to operate, adapt to characteristics such as outdoor environment property is strong, be widely used in 10kV distribution line and distribution transformer primary side as protection with carry out the equipment throwing, cut the usefulness of operation.
Be installed on the 10kV distribution line branch line, can dwindle the power failure scope,, possessed the function of isolating switch, created a safety work environment for maintenance section circuit and equipment, increased maintainer's the sense of security because of it has a tangible cut-off point.Be installed on the distribution transformer, can be used as the main protection of distribution transformer.
The utility model content
In view of this, the purpose of the utility model provides a kind of outdoor high-voltage drop type fuse.
The technical scheme of the utility model realizes with following method,
A kind of outdoor high-voltage drop type fuse mainly is provided with fusion tube and insulator, and fusion tube is electrically connected through moving contact with the insulator upper end; Fusion tube is electrically connected through fixed contact with the insulator lower end, also is provided with draw ring on the moving contact, wherein; The first end of stationary contact is hinged on the fusion tube; The other end is a link, and link is fixedly connected with the insulator lower end, and the fusion tube lower end also is provided with disconnector and fusion tube strengthens adapter sleeve; Disconnector is provided with the disengaging assembly that fixed contact is separated with disconnector, also is provided with protective cover on the moving contact.
Breaking away from assembly is the alloy fuse piece that is arranged between disconnector and the fixed contact.
