Abstract
The invention relates to a full-sealing fuse. The full-sealing fuse comprises a body ceramic sleeve, wherein an upper outlet lead and a lower outlet lead are respectively arranged at two sides of the body ceramic sleeve and respectively connected with the body ceramic sleeve through rubber sleeves in a transition mode, an upper electrode and a lower electrode corresponding to the upper outlet lead and the lower outlet lead are arranged inside the body ceramic sleeve, and a fuse tube with a fuse wire is arranged inside the body ceramic sleeve and is connected with the upper electrode and the lower electrode. The full-sealing fuse has the advantages that the insulating performance is good, the fuse is fully insulated, all electrified portions are covered inside, the phenomena like abnormal heating and burning loss of the electrified portions caused by pollution are avoided, and safe use of the fuse is guaranteed.
Description
Technical field
The present invention relates to a kind of fuse, especially a kind of hermetically sealed fuse.
Background technology
The fusion tube of existing fuse switch generally is the outside that is overlapped on the body insulator, and its poor sealing can cause creepage distance to shorten, and causes faults such as short circuit, open circuit, has the foreign matter overlap joint on the electrode, causes forming big electric current.
Summary of the invention
The present invention will solve the shortcoming of above-mentioned prior art, and a kind of safe and reliable hermetically sealed fuse is provided.
The present invention solves the technical scheme that its technical problem adopts: this hermetically sealed fuse, comprise the body insulator, the both sides of body insulator are respectively equipped with the upper outlet lead-in wire and export lead-in wire down, upper outlet lead-in wire and being connected by the rubber sleeve transition between outlet lead-in wire and the body insulator down, be provided with in the body insulator and upper outlet lead-in wire and the outlet lead-in wire is corresponding down upper electrode and lower electrode, the fusion tube that has a fuse is located at body insulator inside and is connected with lower electrode with upper electrode.
As preferably, described body insulator bottom is provided with seal cover.
As preferably, the bottom of described body insulator is provided with tapered seal closure.
As preferably, described fusion tube comprises fusion tube upper electrode and the fusion tube lower electrode with fuse two end in contact, wherein the fusion tube lower electrode divides for movable part and the standing part that is connected by spring, movable part is provided with bolt, fuse is connected with lead, lead and bolt by passing internally behind the compression fusion tube lower electrode.
As preferably, described fusion tube upper electrode is provided be used to opening the metal cap that fuse is placed in the back.
As preferably, the part that described fuse contacts with the fusion tube upper electrode is provided with the metal roof of cap shape.
As preferably, described body insulator is provided with the installation anchor ear.
Inventing useful effect is: insulating properties of the present invention is better, all insulationization, and all charged positions are inner cover, stop it because contaminated and situations such as the abnormal heating that causes, scaling loss have been guaranteed the safe handling of fuse.

Description of reference numerals: upper outlet lead-in wire 1, body insulator 2 is installed anchor ear 3, following outlet lead-in wire 4, seal closure 5, seal cover 6, rubber sleeve 7, fusion tube 8, fusion tube upper electrode 81, fusion tube lower electrode 82, metal cap 83, spring 84, bolt 85, movable part 86, standing part 87, fuse 9, metal roof 91, lead 92.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
Embodiment: as Fig. 1-4, this hermetically sealed fuse, comprise body insulator 2, body insulator 2 upper ends are provided with the upper outlet lead-in wire 1 that is connected to distribution line, below one side is provided with the following outlet lead-in wire 4 that is connected to transformer side, upper outlet lead-in wire 1 and being connected by rubber sleeve 7 transition between outlet lead-in wire 4 and the body insulator 2 down, be provided with in the body insulator 2 and upper outlet lead-in wire 1 and outlet lead-in wire 4 is corresponding down upper electrode and lower electrodes, it is inner and be connected with lower electrode with upper electrode that the fusion tube 8 that has a fuse 9 is located at body insulator 2.Body insulator 2 bottoms are provided with seal cover 6, prevent that dust, dirt etc. from entering fuse inside, and the bottom of insulator 2 is provided with tapered seal closure 5 and seal cover 6 is covered in wherein.
Seal cover 6 need be opened when fusion tube 8 is installed, utilize special-purpose operating grip, and pass through the tapered guide of seal closure 5, fusion tube 8 is put in body insulator 2 inside, and contact with lower electrode with upper electrode.Fusion tube 8 comprises fusion tube upper electrode 81 and the fusion tube lower electrode 82 with 9 liang of end in contact of fuse, wherein fusion tube lower electrode 82 divides for movable part 86 and the standing part 87 that is connected by spring 84, movable part 86 is provided with bolt 85, at first the metal cap 83 on the fusion tube upper electrode 81 is opened during installation, fuse 9 is put into fusion tube 8, compress fusion tube lower electrode 82 then, because fuse 9 is connected with lead 92, it after passing, standing part 87 is wrapped on the bolt 85, thus movable part 86 and standing part 87 compressions is fixing.Fuse 9 one ends are connected with fusion tube lower electrode 82 by lead 92, and an end contacts with fusion tube upper electrode 81 by the metal roof 91 of cap shape.
During work, fuse by being installed, is installed on the gold utensil in anchor ear 3 settings, behind the fuse failure, the movable part 86 of fusion tube lower electrode 82 and standing part 87 are removed the constraint of lead 92 and bolt 85, under the effect of spring 84, fusion tube 8 produces downward reaction force, adds the gravity of fusion tube 8 self, and fusion tube 8 drops downwards after backing down seal cover 6.Seal closure 5 protection seal cover 6 in it is not contaminated, corrosion etc., successfully comes off automatically during fault to guarantee seal cover 6 again.
In addition to the implementation, the present invention can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of requirement of the present invention.
