Description
Technical field
The utility model relates to power grid arrester technical field, specially a kind of arrester that failure is visual.
Background technique
10kV distribution line is the main distribution network in China, which mainly undertakes user oriented and directly provide electric energy
Task.Due to the complicated network structure, the dielectric level of route is low, and operation and maintenance level and the transmission line of electricity of route have biggish
Gap, distribution network are easily subject to lightning strike accident, cause insulator arc-over, broken string or trip accident, cause national economy and
People's life is impaired.Especially in recent years with economic rapid development, requirement of the people to power quality is also higher and higher, to matching
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 the maintenance work amoun for improving power supply reliability and mitigating route
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 increase, and will cause line loss increase, are 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 ground faults of two arresters, will cause switch protection movement and so that user is had a power failure, influence 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 line 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 are difficult to be widely applied.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts provides a kind of artificial manufacture insulator strength weak
Point makes the orientation explosion of arrester housing, finds phenomenon of the failure, the visual arrester of safe and reliable failure in time.
The utility model is achieved through the following technical solutions:
A kind of visual arrester of failure, including arrestor porcelain bushing, plug and capping, the inside of the arrestor porcelain bushing are set
There is the inner cavity for accommodating plug, is equipped with indicating fault portion 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 plug 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 the arrestor porcelain bushing, it is described
Capping is mounted in lumen openings.
As an improvement of the above scheme, the indicating fault portion is at least one of annular groove.
As an improvement of the above scheme, the periphery of the arrestor porcelain bushing is equipped with the installation for connecting with mounting bracket
Portion.
As an improvement of the above scheme, the cross sectional shape of the annular groove is arc-shaped or polygon.
The utility model has the following beneficial effects:
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 route；Arrester after self-destruction checks that appearance just can determine whether operating status, reduces trouble shooting time.
3) structure is simple, ingenious, and arrester is detached to be realized by self structure, does not need additional other equipment, machine of threading off
Structure is reliable.
4) after arrester aging, fragment will not splash, and hurt other equipment and personal safety.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the visual arrester of failure of the utility model.
Description of symbols: arrestor porcelain bushing 1, plug 2, capping 3, inner cavity 4, annular groove 5, adhesive layer 6, mounting bracket 7,
Mounting portion 8, high-field electrode 9.
Specific embodiment
Embodiment 1
As shown in Figure 1, a kind of visual arrester of failure, including arrestor porcelain bushing 1, plug 2 and capping 3, described is lightning-arrest
The inside of device insulator 1 is equipped with the inner cavity 4 for accommodating plug 2, sets in arrestor porcelain bushing 1 close to one end periphery that inner cavity 4 is open
There are three annular grooves 5 being axially distributed, the thickness of the annular groove 5, intensity are below the other parts of arrestor porcelain bushing 1；
The cross sectional shape of the annular groove 5 is rectangle.The plug is packed into the inner cavity 4 of arrestor porcelain bushing 1 and in the gap of inner cavity 4
Filling adhesive forms adhesive layer 6, and the adhesive layer 6 is for sealing and avoiding arrestor porcelain bushing 1 to fly because explosion generates fragment
It splashes；The high-field electrode 9 being connected to plug 2 is loaded onto the arrestor porcelain bushing 1, the capping 3 is mounted on the opening of inner cavity 4
On.The periphery of the arrestor porcelain bushing 1 is equipped with the mounting portion 8 for connecting with mounting bracket 7.
