Description
Technical field
The present invention relates to the novel fuse protection device of electric distribution network overhead wire, belong to electrical network prevent and reduce natural disasters technology neck
Territory.
Background technology
The fuse protection device product almost all that domestic electrical company uses at present is tradition fuse switch, and greatly
Mostly being homemade goods, only minority Utilities Electric Co. uses imported product.And the tradition structural manufacturing process of fuse switch and right
The requirement of manufacturing condition is not the most the highest, and the producer possessing production capacity the most both at home and abroad is countless, and factory greatly
Management level, technique, the raw material of family, manufacture, assemble, the link such as test the highest.Therefore there is techniques below defect:
1) tradition fuse switch constructs reason due to it, and insulating properties are the highest, therefore easily owing to the environment such as raining, make moist
Factor causes electrode rust dead, causes the adverse consequences that can not cut-off；
2) cartridge fuse be caught in the rain make moist reinforcement sunshine after it may happen that expand, cause fuse to be pulled off, cause accidental power failure, these
All make fuse easily damage, affect its safe operating life；
3) not exclusively seal due to the charging position of conventional fuse, in riverine, the coastal and work of the inclement conditions such as dust, salt dirt
The areas such as industry garden, electrode easily occurs burn into rust to wait indefinitely damage, and weatherability is very poor.
Summary of the invention
It is an object of the invention to the deficiency overcoming prior art to exist, it is provided that a kind of simple in construction, easy to operate, use
Safe and reliable, it is easy to safeguard, all insulation, bird pest hermetically sealed, anti-, fuse can be protected with the fusing of reusable overhead transmission line
Protect device.
It is an object of the invention to complete by following technical solution: a kind of overhead transmission line fuse protection device, its bag
Include that a top is provided with electrode, bottom is provided with bottom electrode, middle cavity is provided with the body of arc-extinguishing unit and cartridge fuse
Insulator, described body insulator upper end is provided with and the upper outlet integrated rubber sleeve of lead-in wire, and the centre of this rubber sleeve is stretched
Go out and have upper outlet to go between；It is configured with fixing rubber seal cover on the end face oral cavity of bottom, and the avris in this bottom draws
Go out to have lower outlet lead-in wire integrated with rubber bodies, be provided with in the middle of described body insulator and body insulator is installed to gold utensil
On installation anchor ear.
As preferably: described body insulator upper end is fixed with the rubber sleeve in taper angle shape, and described rubber bodies is
The reducing rubber column of the tail shape being fixed on body insulator sidewall is constituted；Another being further opened with on described rubber seal cover is used
In cartridge fuse being put into the opening of body insulator inner chamber, and it is configured with on this opening by being combined for sealing rubber with a lid
The sealing lid in glue seal closure upper shed portion.
The present invention is a kind of improvement to prior art, and it uses integrated structure, improves insulating properties, reduces installation absolutely
Edge distance；Fuse and charged position are the most built-in, are not susceptible to filth；Charging position is built-in, and electrode is difficult to get rusty；Anti-antacid
Rain, the mal-condition corrosion to electrode such as salt is dirty；Avoiding fuse switch cartridge fuse to make moist because drenching with rain in addition can after strong sunshine
The accidental power failure that the expansion that can occur causes fuse to be pulled off and causes；Outlet uses the integrally formed structure of rubber, effectively prevents
Dust pollution, salt are dirty, reinforced insulation safety, it is ensured that long-time stability；Top and the bottom electrode uses such as petal type contact side
Formula, high stability；Use such as slit arc quenching method, there is high security performance；Use import or high-quality fuse, tool
Standby excellent fusing curve.
The present invention has simple in construction, easy to operate, safe and reliable, it is easy to safeguard, all insulation, bird hermetically sealed, anti-
Evil, fuse such as can reuse at the feature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 1, and a kind of overhead transmission line of the present invention melts
Cut-off protector part, it includes, and a top is provided with electrode, bottom is provided with bottom electrode, be provided with arc-extinguishing unit in middle cavity
With the body insulator 1 of cartridge fuse, described body insulator 1 upper end is provided with and goes between 2 integrated rubber sleeves with upper outlet
3, the centre of this rubber sleeve 3 is extended with the upper outlet lead-in wire 2 connecting upper electrode；It is configured with fixing on the end face oral cavity of bottom
Rubber seal cover 4, and the avris in this bottom leads to lower outlet lead-in wire 6 integrated with rubber bodies 5, this lower outlet is drawn
Line 6 is connected to bottom electrode；It is provided with, in the middle of described body insulator 1, the installation anchor ear 7 being installed on gold utensil 9 by body insulator.
Shown in figure, body insulator 1 upper end of the present invention is fixed with the rubber sleeve 3 in taper angle shape, and described
Rubber bodies 5 is that the reducing rubber column in tail shape being fixed on body insulator 1 sidewall is constituted；Another at described rubber seal cover
Be further opened with the opening for cartridge fuse being put into body insulator 1 inner chamber on 4, and be configured with on this opening by with a lid
In conjunction with the rubber closure 8 for caulking gum seal closure 4 upper shed portion.
The present invention is primarily directed to tradition, and fuse switch insulating properties are the highest, fragile, easy-to-rust, misoperation, conjunction
The problems such as lock success rate is low, use integration insulator seal closed form spray structure and new type fuse, possess good antifouling, anti-without reason
Barrier comes off, anti-operation is dangerous, close a floodgate fast, good arc-suppression function, can effectively protect fuse, reinforced insulation safety, expire
Service requirement steady in a long-term under the severe environmental conditions such as the most coastal and industrial occupancy of foot.
Invention have the technical effect that hermetically sealed, all insulation, reach anti-to get rusty, salt moistureproof, anti-bird pest dirty, anti-, preventing heavy metal
The effect that haze etc. corrode, even if can reuse again after fuse changes fuse after short trouble simultaneously.
(1) aerial line fuse protection device realizes hermetically sealed, conductor and protection all realize hermetically sealed, resist external humidification,
Ability along adverse circumstances such as sea salt dirt, heavy metal corrosion is strengthened；
(2) aerial line fuse protection device realizes all insulation, uses high-quality porcelain vase, can be greatly enhanced insulating properties, also can phase
To reducing installation insulation distance, be conducive to installing and using in the position of limited space；
(3) fuse can be reused, and service life, top and the bottom electrode used such as petal type typically at about 10 years
Contact mode, high stability, fuse, after circuit fusing, does not interferes with this running body；
(4) for the climatic characteristic in sea salt area, in spring, the busy season of season in autumn two avian reproduction, this fuse is used significantly to increase
Strong distribution network overhead line is to bird pest defensive ability/resistance ability.
(5) strengthen overhead transmission line reliability of operation, due to cartridge fuse do not have exposed outside, it is to avoid tradition drop type fusing
Device cartridge fuse because drenching with rain, making moist, in addition after strong sunshine it may happen that the fuse expanding and causing is pulled off, cause accidental power failure
Accident.
