Net power supply reliability is put forward higher requirements.In order to realize the safe and stable operation of electric system, installation good using lightning protection effect
It safeguards simply and easily lightning protection product, there is important meaning to improving power supply reliability and mitigating the maintenance work amoun of circuit
Justice.
In long-term use, the main components varistor of Zinc-Oxide Arrester bears work to conventional oxidation zinc arrester
Voltage and different amplitudes, instantaneous lightning surge, the switching overvoltage of pulsewidth, electric property can be deteriorated gradually, if arrester is not
Breakdown completely, arrester leakage increases, line loss can be caused to increase, be unfavorable for the economical operation of power network, if arrester is breakdown,
One-point grounding fault is caused, since surge arrester failure is hidden failures, needs to consume a large amount of human and material resources trouble-shooting points；If
There are the different separate earth faults of two arresters, switch protection can be caused to act and user is made to have a power failure, influences to produce and live.
It can explode after existing Zinc-Oxide Arrester failure, the fragment of arrester splashes around, it may occur that fragment hurts sb.'s feelings,
Involve the accidents such as other equipment around, cause the accident expansion.
The disengaging of existing 10kV distribution lines arrester be rely on arrester lower end series connection thermal explosion disconnector to realize, but
Because of the structure and quality of thermal explosion disconnector, it is easy to happen " malfunction " and " tripping ", influences the lightning protection effect of arrester, and by
Cost and construction reason, it is difficult to be widely applied.
Invention content
The purpose of the present invention is overcoming the above-mentioned prior art, a kind of artificial manufacture insulator strength weak point is provided,
Make the orientation explosion of arrester housing, finds phenomenon of the failure, the visual arrester and preparation method thereof of safe and reliable failure in time.
The present invention is achieved through the following technical solutions：
A kind of production method of the visual arrester of failure, is as follows：
Step 1. processes indicating fault portion, institute by kerve technology in the lower end periphery of arrestor porcelain bushing in its outer surface
The thickness in the indicating fault portion stated, intensity are below the other parts of arrestor porcelain bushing；
Step 2. be packed into inside arrestor porcelain bushing plug and in arrestor porcelain bushing between plug filling adhesive, it is described
Adhesive be used to seal and avoid the indicating fault portion of arrestor porcelain bushing to splash because explosion generates fragment；
Step 3. loads onto the high-field electrode being connected to plug in arrestor porcelain bushing, and envelope is loaded onto in the opening of arrestor porcelain bushing
Lid.
As the improvement of said program, the indicating fault portion is at least one of annular groove.
As the improvement of said program, the adhesive is fine containing polyvinyl alcohol, liquid silastic, hydroxypropyl methyl
Tie up the water-soluble binder of element.
As the improvement of said program, the cross sectional shape of the annular groove is arc-shaped or polygon.
A kind of visual arrester of failure, including arrestor porcelain bushing, plug and capping, the inside of the arrestor porcelain bushing are set
It is useful for the inner cavity of accommodating plug, indicating fault portion is equipped with close to one end periphery of lumen openings in arrestor porcelain bushing, it is described
The thickness in indicating fault portion, intensity are below the other parts of arrestor porcelain bushing, and the core is packed into the interior of arrestor porcelain bushing
Chamber simultaneously forms adhesive layer in the gap filling adhesive of inner cavity, and the adhesive is used to seal and avoid the event of arrestor porcelain bushing
Hinder instruction unit to splash because explosion generates fragment；The high-field electrode being connected to plug is loaded onto in the arrestor porcelain bushing, it is described
Capping is mounted in lumen openings.
As the improvement of said program, the indicating fault portion is at least one of annular groove.
As the improvement of said program, the periphery of the arrestor porcelain bushing is equipped with the installation for being connect with mounting bracket
Portion.
As the improvement of said program, the cross sectional shape of the annular groove is arc-shaped or polygon.
The invention has the advantages that：
1) easy for installation, it is directly parallel on insulator steel cap, does not change original rod-type and insulator, it is easy for installation, it can
It substantially reduces construction cost and reduces maintenance work, and will not go offline, the failures such as single-phase earthing, do not influence normal power supply,
Power failure machine to be had can be replaced directly.
2) there is failure to warn, detachment function.When non-linear lightning protection component breaks down, arrester can orient self-destruction,
Automatically it is detached from circuit；Arrester after self-destruction checks that appearance just can determine whether operating status, reduces trouble shooting time.
3) simple in structure, ingenious, arrester is detached to be realized by self structure, does not need additional other equipment, dropout machine
Structure is reliable.
4) after arrester aging, fragment will not splash, and hurt other equipment and personal safety.
