Description
Technical field
The utility model relates to arrester fields, and in particular to arrive a kind of arrester.
Background technique
Arrester is divided into many kinds, there is a metal oxide arrester, Line type's MOA, continuously gap line
Type metal oxide arrester, all insulation polymeric metal oxide surge arrester, detachable lightning arrester.
The main Types of arrester have tube type arrester, valve-type arrester and Zinc-Oxide Arrester etc..Each type is lightning-arrest
The main operational principle of device is different, but their work be substantially it is identical, be provided to the protection communications cable and logical
Believe that equipment is without damage.
There is a kind of gap arrester on the market at present, however the discharging gap of this gap arrester is non-adjustable mostly
, it is inconvenient to use.
Utility model content
In order to overcome the shortcomings of background technique, the utility model provides a kind of arrester, mainly solves present gap
The discharging gap of arrester is nonadjustable, inconvenient problem with use mostly.
The technical scheme adopted by the utility model is
A kind of arrester, including ontology, are connected with the first guide rod and the second guide rod on the ontology, first guide rod and
It is equipped with discharging gap between second guide rod, is equipped with the first threaded hole and the second threaded hole on the ontology in the horizontal direction, it is described
First guide rod is L-type structure, and including the first bar being threadedly coupled with first threaded hole, first bar outer end is equipped with downward
The second bar extended, second boom end are chondritic；Second guide rod is line-styled structure, second guide rod
One end is threadedly coupled with second threaded hole, and other end end is chondritic.
Insulation sleeve is coated in the first bar peripheral outer wall.
The ontology is equipped with boss, and described insulation sleeve one end inner wall and the outer wall of boss are engaged by clamping.
Locking nut is also connected on first bar, the locking nut front end face and the outside the boss end face are tight
Pressure.
The body outer wall is equipped with several parachute skirts.
The parachute skirt includes the big full skirt being relatively large in diameter and the lesser small full skirt of diameter, the big full skirt and described small
Full skirt is uniform staggered on the ontology axial direction.
The upper surface of the big full skirt is equipped with several reinforcing ribs extended along the big full skirt radial direction.
The ontology peripheral outer wall is also wrapped on alkali-free glass fibre layer, and the alkali-free glass fibre layer is set to the ontology
Between outer wall and the parachute skirt inner wall.
The beneficial effects of the utility model are: the utility model provides a kind of arrester, the first guide rod and the second guide rod
It is adjustable, and then the size of adjustable discharging gap, using effect is more preferably.
Detailed description of the invention
Fig. 1 is the schematic cross-sectional view of the utility model one embodiment.
Fig. 2 is the enlarged diagram in Fig. 1 at A.
Fig. 3 is the top view of the big full skirt of the utility model one embodiment.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing: a kind of arrester, including ontology 1, on the ontology
It is connected with the first guide rod 2 and the second guide rod 3, discharging gap 4, the ontology are equipped between first guide rod 2 and the second guide rod 3
On be equipped with the first threaded hole 11 and the second threaded hole 12 in the horizontal direction, first guide rod is L-type structure, including with described the
The first bar 111 that one threaded hole is threadedly coupled, first bar outer end are equipped with the second bar 112 extended downwardly, second bar
End is chondritic；As shown, second guide rod is line-styled structure, second guide rod and described second
Threaded hole is threadedly coupled, and other end end is chondritic.First bar is threadedly coupled with ontology, the position of adjustable installation
It sets, which is threadedly coupled with the second threaded hole, also the position of adjustable installation, to realize the adjusting of discharging gap.
In the present embodiment, as shown, being coated with insulation sleeve 1111 in the first bar peripheral outer wall.It prevents from leaking electricity.
In the present embodiment, as shown, the ontology be equipped with boss 15, described insulation sleeve one end inner wall with it is described convex
Platform outer wall is engaged by clamping.It is easy for installation.
In the present embodiment, as shown, being also connected with locking nut 113 on first bar, before the locking nut
Press with the outside the boss end face end face.Installation is firm.
In the present embodiment, as shown, the body outer wall is equipped with several parachute skirts.Increase creepage distance.
In the present embodiment, as shown, the parachute skirt includes that the big full skirt 261 being relatively large in diameter and diameter are lesser
Small full skirt 262, the big full skirt 261 and the small full skirt 262 are uniform staggered on the ontology axial direction.
In the present embodiment, as shown, the upper surface of the big full skirt 261 is equipped with along the 261 radial direction side of big full skirt
To several reinforcing ribs 5 of extension.Increase big full skirt intensity.
In the present embodiment, as shown, the ontology peripheral outer wall is also wrapped on alkali-free glass fibre layer 6, the nothing
Alkali containing glass fibre layer 6 is set between 1 outer wall of ontology and the parachute skirt inner wall.Since alkali-free glass fibre has tension
The high feature of load is stretched, in this way when arrester is by lightning stroke burning, prevents core four from dissipating and blows, improve anti-flammability
Can, using safer.
