Abstract
A fully isolated high voltage dropping fuse is wrapped by isolating materials to be an option of silastic in which outer insulating material of fuse carrier is independently coated and other parts of up-lower connecting terminals, arc-suppressing cover are wrapped wholly by insulating materials. This invention realizes true complete isolation for over head insualting circuit and avoids discharging faults appearing to the outer objects.
Description
The present invention relates to power circuit system and outdoor transformer equipment, more specifically relate to the protective device of insulated overhead line.
China's electric power system at present generally adopts insulated overhead line in urban distribution network, its use amount accounts for more than 70% of distribution.In insulated overhead line, be extensive use of high voltage drop-out type fuse cutout; and existing high voltage drop-out type fuse cutout on it lower connecting terminal, fusing carrier expose; there is not any insulation protection; this just makes insulated overhead line greatly reduce its insulation effect, brings hidden danger for the electrical power distribution system safe operation.
The purpose of this invention is to provide a kind of full-insulating high-voltage drop-off fuse, it is coated that this fuse carries out outer cover with insulating material with existing high voltage drop-out type fuse cutout, make high voltage drop-out type fuse cutout and external insulation, avoid or reduce the various accidents of insulated overhead line.
In order to achieve the above object, the present invention adopts following technical scheme: it is coated with insulating material existing high voltage drop-out type fuse cutout to be carried out outer cover, wherein the exterior insulation material of fusing carrier is coated separates the remainder insulating material integrated cladding of fuses such as upper and lower binding post, arc-extinguish chamber with other parts.
The present invention compared with prior art has following advantage: (1) is coated by with insulating material existing high voltage drop-out type fuse cutout being carried out outer cover, and fuse will keep insulation with the external world, make insulated overhead line realize real all insulation state; (2) owing to upper and lower binding post, fusing carrier, arc-extinguish chamber etc. all use insulating material coated, avoided causing its discharge accident to exterior objects such as branches because of exposing of parts such as upper and lower binding post, fusing carriers; (3) owing to have tangible cut-off point when guaranteeing line maintenance coated separation of the coated insulation of insulation of fusing carrier with other parts; (4), thereby make full-insulating high-voltage drop-off fuse can become the regeneration product of high voltage drop-out type fuse cutout miniaturization, freedom from repairs because the present invention has above-mentioned advantage.
Fig. 1 is a kind of schematic diagram of full-insulating high-voltage drop-off fuse.
Following according to Fig. 1, the present invention is further illustrated.
With insulating material that the outer cover of upper connecting terminal 1, lower connecting terminal 2, arc-extinguish chamber 3, fusing carrier 4 is coated with insulating material 5, wherein the exterior insulation material of fusing carrier is coated separates the remainder insulating material integrated cladding of fuses such as upper and lower binding post, arc-extinguish chamber with other parts.
Embodiment:
Insulating material is selected silicon rubber for use, the outer cover of upper connecting terminal, lower connecting terminal, arc-extinguish chamber, fusing carrier is coated with silicon rubber, wherein the outer silicone of fusing carrier is coated separates the remainder insulating material integrated cladding of fuses such as upper and lower binding post, arc-extinguish chamber with other parts.
Claims (2)
1, a kind of full-insulating high-voltage drop-off fuse mainly is made up of upper connecting terminal (1), lower connecting terminal (2), arc-extinguish chamber (3) and fusing carrier (4), it is characterized in that, the outer cover of this fuse is coated with insulating material (5).
2, a kind of full-insulating high-voltage drop-off fuse according to claim 1, it is characterized in that, described outer cover is coated, and wherein the exterior insulation material of fusing carrier is coated separates the remainder insulating material integrated cladding of fuses such as upper and lower binding post, arc-extinguish chamber with other parts.
