Abstract
The utility model discloses a drop-out type hidden fusion tube all-insulation fuse, which is characterized in that the inner cavity of an insulating sleeve is hollow, a fusion tube is arranged in the inner cavity of the insulating sleeve, moving contacts and fixed contacts are arranged on the inner wall of the insulating sleeve, the moving contacts and the fixed contacts are positioned on the inner wall of the insulating sleeve at two ends of the fusion tube, and a compression spring is arranged at one end of the fusion tube. The fuse effectively solves the problem of the non insulation of partial nodes of an insulation wire, has light structure, is especially suitable for all insulated insulation wires, and mainly comprises three parts, namely, the insulating sleeve, the fusion tube, and the moving contact and the fixed contact. The fixed contacts are arranged at the upper end and the lower end of the inner wall of the insulating sleeve, a mounting plate is fixed in the middle of the sleeve, the fusion tube is made of composite material, the fuse not only has good breaking capacity, but also has the quick drop-out function. The product has reasonable structural design and strong practicability.
Description
Technical field:
The utility model relates to the technical field of electric power system distribution system, and a kind of specifically circuit is crossed the built-in fusion tube all insulation of the drop type fuse of flow of power protection, particularly its mechanical connecting structure.
Background technology:
All fuse switches all mainly comprise fusion tube and contact (seat) and insulator three parts composition at present, this structure fuse fusion tube and contact (seat) all expose, quickening along with distribution line insulating process, these charged positions of exposing become one of source of trouble of circuit outside destroy, press for to adopt technical measures to be improved.
The utility model content:
The purpose of this utility model is to provide the built-in fusion tube all insulation of a kind of drop type fuse, its structure is light and handy, be particularly suitable for all insulation circuit and adopt, it can realize the drop type work of fusion tube under all insulation state, overcome the shortcoming and defect that exists in the prior art.
To achieve these goals, the technical solution of the utility model is: the built-in fusion tube all insulation of a kind of drop type fuse, it mainly comprises insulating sleeve, it is characterized in that: insulating sleeve inner chamber hollow, the insulating sleeve inner chamber is provided with fusion tube, insulating sleeve inwall place is provided with dynamic/static contact, and dynamic/static contact is positioned at the insulating sleeve inwall place at fusion tube two ends, and an end of fusion tube is provided with holddown spring.
The utility model discloses the built-in fusion tube all insulation of a kind of drop type fuse, its can effectively solve insulated circuit part of nodes nonisulatedization problem and structure light and handy, being particularly suitable for all insulation circuit adopts, fuse mainly is made up of insulating sleeve, fusion tube and dynamic/static contact three parts, fixed contact is installed in insulating sleeve inwall two ends up and down, mounting panel is fixed in the middle of the sleeve pipe, fusion tube is a composite material, it not only has connecting-disconnecting function preferably, and have and fall function fast, this product structure design is reasonable, and is practical.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a holddown spring impaction state structural representation.
Fig. 3 presses the relaxation state structural representation for holddown spring.
Embodiment:
With reference to the accompanying drawings, the utility model further is described
The utility model is the built-in fusion tube all insulation of an a kind of drop type fuse, as Fig. 1 as shown in it, it mainly comprises insulating sleeve 1, it is characterized in that: insulating sleeve 1 inner chamber hollow, insulating sleeve 1 inner chamber is provided with fusion tube 2, insulating sleeve 1 inwall place is provided with dynamic/static contact 3, dynamic/static contact 3 is positioned at the insulating sleeve 1 inwall place at fusion tube 2 two ends, one end of fusion tube 2 is provided with holddown spring 4, fuse 5 one ends of holddown spring 4 usefulness bracelets compress, the other end of fuse 5 is connected with fusion tube, and holddown spring 4 one ends are fusion tube 2, and the other end of holddown spring 4 props up the step 5 at insulating sleeve 1 inwall place.
Product is fixed on the installing rack by mounting panel.Be connected in the distribution line during fuse operation, when operate as normal, the fuse of bracelet compresses holddown spring, and when distribution line broke down, fault current produced free gas with the fuse quick-break.Holddown spring discharges behind the fuse failure, and under the pressure effect of spring, fusion tube falls rapidly pulls out the fuse buttock line, makes arc extinction.Falling of fusion tube forms tangible breaking gap.
