Description
Technical field
This utility model relates to a kind of power equipment, particularly relates to a kind of for open air, especially seems the zinc oxide in field
Anti-thunder insulator.
Background technology
Zinc oxide anti-thunder insulator is a kind of common power equipment.The product of zinc oxide anti-thunder insulator in prior art
Structure is very simple, consists of upper and lower gold utensil, dwell set, zinc oxide resistance sheet, epoxy cylinder.
The wherein effect of dwell set: discharged by dwell set when of thunder and lightning effect, between passing through the when that thunder and lightning not acting on
Gap isolation line voltage distribution avoids zinc oxide resistance sheet voltage ageing.When circuit by Lightning Over-voltage and not yet reaches insulator arc-over
During voltage, gap starts electric discharge, afterwards by spacer ring, overcurrent is guided zinc oxide resistance sheet, and is discharged into greatly through resistor disc
Ground.
And prior art there is problems in that
1, after equipment fault from display capabilities.When after device fails, owing to faulty equipment is at tower masthead end, it is impossible to
Clearly recognize faulty item.Additionally when line walking at night, it more difficult to find faulty equipment.
2, anti-thunder insulator single-phase earthing probability is reduced.When lightning current energy is excessive, internal pressure cannot be released in time
Put, the structure within destruction, cause equipment single-phase earthing.
3, the impact after equipment explosion is prevented.Internal pressure is excessive, it is impossible to discharge in time, and equipment cannot bear, overall fried
Split and drop.There is potential safety hazard.
It is true that when original product breaks down, body occurs slight crack, form the single-phase earthing of circuit.Circuit event
After barrier is reported to the police, when trouble-shooting product, owing to tower bar height is at 10m 12m, it is difficult to find faulty item.
Utility model content
The purpose of this utility model is to provide indicating fault type zinc oxide anti-thunder insulator, the energy when breaking down warning
It is quickly found out faulty insulator to change in time, avoids insulator entirety simultaneously and burst to drop and cause unexpected injury.
In order to realize described purpose, this utility model indicating fault type zinc oxide anti-thunder insulator, by upper gold utensil, lower gold
Tool, dwell set, zinc oxide resistance sheet, epoxy cylinder form, and are surrounded by insulating coating outside described epoxy cylinder, and described epoxy cylinder is provided with
The pressure relief opening of at least one pair of symmetry, epoxy cylinder outer sheath is connected to indicating fault ring, fills nail and is fixed on by indicating fault ring
Pressure relief opening position, described epoxy cylinder scribbles bright-coloured reflector layer.
Preferably, to be not more than two right for described pressure relief opening quantity.Too much pressure relief opening can cause bulk strength
Decline.
Preferably, pressure relief opening is arranged on epoxy cylinder from top to bottom at 70mm.Determine that a position arranges pressure and releases
Discharge hole is conducive to maintainer to find whether failure judgement occurs.
Preferably, described epoxy cylinder is only equipped with reflector layer at corresponding indicating fault.The most not only save material, Er Qieke
To avoid other events to cause reflector layer to expose the erroneous judgement brought.
Preferably, described nail of filling is aluminium nail.Aluminium nail light weight, easy for installation, it is best suitable for such occasion.
Preferably, described reflector layer is yellow.Yellow is the most bright-coloured, it is simple to observation.
Preferably, described insulating coating is silastic material, and described silastic material paints redness.Reddish yellow aberration is obvious,
And the silastic material of redness can play the effect of certain bird dispelling.
By such structure, when suffering multiple thunderbolt and direct stroke generation anti-thunder insulator internal flashover fault,
Internal gas is heated, and pressure increases, and washes silastic material open, discharges rapidly internal pressure, thus prevents and wash gold utensil, fried open
The situation splitting epoxy cylinder occurs, and protection insulated conductor is injury-free.The gas that simultaneous faults indicating ring is released is washed open and is dropped, shape
Become significantly mark, make the anti-thunder insulator that can find to break down during operation maintenance personnel inspection circuit very easily, enter
Row is changed.
By such setting, this utility model indicating fault type zinc oxide anti-thunder insulator is possible to prevent equipment in thunderbolt
During burst owing to internal pressure is excessive, improve equipment safety.Also reduce simultaneously and cause tables of equipment owing to inside bursts
The probability of phase ground connection, improves power supply reliability.Even if also increasing the fault ability from display when breaking down, conveniently look in time
Look for and more exchange device.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of this utility model indicating fault type zinc oxide anti-thunder insulator.
Fig. 2 is pressure relief opening position when not installing filling nail of this utility model indicating fault type zinc oxide anti-thunder insulator
Put each Rotating fields and resolve schematic diagram.
Detailed description of the invention
As shown in Figure 1 and Figure 2: indicating fault type zinc oxide anti-thunder insulator, by upper gold utensil 1, lower gold utensil 2, dwell set, oxygen
Change zinc resistor disc, epoxy cylinder 3 forms, and is surrounded by insulating coating 4 outside described epoxy cylinder 3, and described epoxy cylinder 3 is provided with at least one pair of
Symmetrical pressure relief opening 5, epoxy cylinder 3 outer sheath is connected to indicating fault ring 6, fills nail 7 and indicating fault ring 6 is fixed on pressure
Release aperture 5 position, described epoxy cylinder 3 scribbles bright-coloured reflector layer.It is right that described pressure relief opening 5 quantity is not more than two.Pressure
Release aperture 5 is arranged on epoxy cylinder 3 from top to bottom at 70mm.Described epoxy cylinder 3 is only provided with reflective at corresponding indicating fault ring 6
Layer.Described nail 7 of filling is aluminium nail.Under normal circumstances, described reflector layer is yellow.Described insulating coating 4 is silastic material, institute
State silastic material and paint redness.So aberration is obvious, it is easier to find guilty culprit during easy access.
1, power current is as when anti-thunder insulator is internal.
During power frequency short circuit, short circuit current 1 16kA can make protection switch immediately trip.Owing to relay protection is from accepting signal
To completing tripping operation, need about 0.2 second time at the soonest.The temperature of the heat that power frequency arc produces is up to about 7000 degree, at this
In the case of sample, internal pressure increases can open pressure relief opening 5, so makes indicating fault ring 6 fall, and exposes inside
Reflector layer, it is simple to maintainer finds.
2, when repeatedly thunderbolt or lightning current are more than 65kA.
In these cases, also can improve rapidly the pressure of body interior, make pressure relief opening 5 open.
