Description
Technical field
The utility model relates to high voltage protective technical field, particularly relates to a kind of novel inside and outside double gap explosion-proof multiple
Close pillar insulator.
Background technology
The insulated circuit that power department was selected in recent years is combined pillar zinc oxide anti-thunder insulator, effectively reduces
With the generation preventing insulated conductor breakage caused by lightning stroke.But in actual motion, it has been found that have only a few lightning protection exhausted
Edge breaks down damage, and during as suffered to be struck by lightning by force, interior insulator gas drastically expands, and easily washes gold utensil open
Or destruction epoxy cylinder, particularly operations staff are difficult to the anti-thunder insulator that finds to have damaged when patrolling and examining.According to
Power distribution network runs actual conditions and customer requirement, and my the company technique department special development and production second generation is novel
Dual lightning protection explosion-proof combined column formula insulator.These series of products are for protecting power system transmission line to insulate
The important protection electrical equipment that wire damages from atmospheric over-voltage, provides for distribution line safe operation reliably
Ensure.
Utility model content
The purpose of this utility model is to provide a kind of novel inside and outside explosion-proof compound pillar insulator of double gap, striking
Ring is because having significantly mark, easy-to-look-up trouble point when arc flash is damaged；Insulator is energy after overvoltage
Cutting off power frequency continued flow in time, protection insulated conductor is not blown by electric arc；It is double that interior external series gap makes insulator possess
Weight lightning protection function, arc ring increases the protection domain of insulated conductor and plays striking effect.
To achieve these goals, the utility model have employed following technical scheme: a kind of novel inside and outside double
The explosion-proof compound pillar insulator in gap, including insulator body, described insulator body includes insulating cylinder, sets
Insulation sleeve outside insulating cylinder；
Described insulator body top is provided with clamp piece, and clamp piece is fastened on Insulating A High-Voltage wire；
Described insulator body lower end is provided with installation bolt；
The zinc oxide resistance sheet of a series gap it is provided with in the middle part of described insulator body；
A pair arc ring, described arc ring and zinc oxide resistance sheet phase is added in the middle part of described insulator body
Even.
Wherein, described insulating cylinder has 2 symmetrical pressure relief openings.
Wherein, described insulation sleeve is silicone rubber sleeve.
The beneficial effects of the utility model are: possessing explosion prevention function, dual anti-thunder insulator is because of arc flash
Significantly mark, easy-to-look-up trouble point is had during damage；Insulator and arrester function are in one；During installation
Need not to divest the insulating barrier of insulated conductor or use penetrating cable clamp, will not damage wires insulating barrier, cause rain
Water is from divesting an infiltration, etching insulative wire, and can reduce installation and material cost；With clamp insulator,
Common discharging gap is compared, and dual anti-thunder insulator can cut off power frequency continued flow after overvoltage in time, extinguishes
Electric arc, protection insulated conductor is not blown by electric arc；Inside and outside gap makes insulator possess dual lightning protection function,
Arc ring design increases the protection domain of insulated conductor and plays striking effect.
Accompanying drawing explanation
In order to be illustrated more clearly that the utility model embodiment technical scheme, institute in embodiment being described below
The accompanying drawing used is needed to be briefly described, it should be apparent that, the accompanying drawing in describing below is only this practicality
Novel in order to be illustrated more clearly that the utility model embodiment or technical scheme of the prior art, below by p-
In embodiment or description of the prior art, the required accompanying drawing used is briefly described, skill common for this area
From the point of view of art personnel, on the premise of not paying creative work, it is also possible to obtain other according to these accompanying drawings
Accompanying drawing.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is plan structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical side in the utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that the utility model part is real
Execute example rather than whole embodiments.Based on the embodiment in the utility model, ordinary skill people
The every other embodiment that member is obtained under not making creative work premise, broadly falls into the utility model
The scope of protection.
The explosion-proof compound pillar insulator of double gap inside and outside one as shown in Fig. 1～2 is novel, including insulator this
Body 1, described insulator body 1 includes insulating cylinder, the insulation sleeve being located at outside insulating cylinder；Described insulator body
1 top is provided with clamp piece 3, and clamp piece 3 is fastened on Insulating A High-Voltage wire 4；In described insulator body 1
Portion is provided with the zinc oxide resistance sheet 5 of a series gap；In the middle part of described insulator body 1, add a pair draw
Arc ring 2, described arc ring 2 is connected with zinc oxide resistance sheet 5.
Bolt 6 is installed by metallic support or wired earth in described insulator body 1 lower end.
Anti-thunder insulator body 1 installs a pair arc ring 2, with internal high energy ZnO resistors sheet 5 phase additional
Even, form external series gap lightning current release channel, when insulated conductor suffers lightning induced voltage, to produce
Wandering plays striking effect, and this structure increases the anti-thunder insulator protection domain to insulated conductor, and
Lightning strike protection effect still can be played when internal clearance lost efficacy.
Built-in electrical insulation cylinder is designed with 2 symmetrical pressure relief openings 7, is suffering that multiple thunderbolt and direct stroke are sent out
Time raw, during anti-thunder insulator internal flashover fault, internal gas is heated, and pressure increases, and washes silicon rubber open
Set, discharges rapidly internal pressure, thus prevents the situation generation washed clamp piece 3 open, burst insulating cylinder, protect
Protect Insulating A High-Voltage wire injury-free.
The gas that arc ring 2 (being also pressure release mark) is released is washed open or deforms, and forms significantly mark,
Make can find very easily out of order anti-thunder insulator during operation maintenance personnel inspection circuit, carry out
Change, thus protect aerial insulated wire line conductor and do not break, it is to avoid system decompression and relay protection action are jumped
The generation of lock situation, it is to avoid because broken string, insulator arc-over or puncture cause the damage of large-area power-cuts and electricity sales amount
Lose or cause great personal injury accident, it is ensured that normal power supply.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
