Abstract
The utility model relates to a metal-oxide lightning arrester of a complex outer sleeve type, which comprises a core body, a puncturing wire clamp and a mounting bolt, wherein the puncturing wire clamp and the mounting bolt are respectively arranged at both ends of the core body, and an insulating cylinder is sealed outside the core body; a silicone rubber complex outer sleeve of formed by once vulcanization is arranged outside the insulating cylinder, and a circular discharge electrode is sleeved on the outer sleeve. The lightning arrester has the advantages of simple operation, excellent sealing performance, high strength resisting extension and bending, low maintenance cost and convenient mounting.
Description
Technical field
The utility model relates to a kind of lightning arrester, especially relates to a kind of line type band series gap insulator composite sheath formula metal oxide arrester.
Background technology
Composite sheath formula metal oxide arrester is that the power transmission and transforming equipment of protection electric power system is avoided the most effective protection electrical equipment of damage such as atmospheric over-voltage or switching overvoltage.10kV and following transmission system are to bear the effect of insulating and supporting in the high voltage overhead power circuit by post insulator at present, because no lightning protection equipment, the flashover or the breakdown accident of insulator happen occasionally, and greatly reduce the reliability of power supply.For avoiding insulator arc-over or breakdown accident to take place, need be installed in parallel lightning arrester protected in addition, so not only increase installation workload, and investment is big, influence the shortcoming such as attractive in appearance of shaft tower.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of line type band series gap insulator composite sheath formula metal oxide arrester that the post insulator function has the lightning protection function that has concurrently at the prior art present situation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this composite sheath formula metal oxide arrester, wire clamp and construction bolt that it includes core body and is positioned at two, it is characterized in that described core body is encapsulated with insulating cylinder outward, insulating cylinder outside mold pressing is the silicon rubber composite sheath of sulfidization molding once, puts outward and is arranged with the ring discharge electrode.
Described wire clamp adopts the penetration type structure.
Compared with prior art, advantage of the present utility model is: owing to have the function of insulator support function and lightning protection simultaneously, improved the power supply reliability of transmission system greatly; The requirement that simultaneously lightning arrester need not be installed has in addition again promptly reduced cost and has improved installation effectiveness again, thereby significantly reduced the workload of maintenance cost and operation maintenance.The wire clamp structure is a penetration type, especially is used in high-voltage insulating wire, can peel off the high-voltage conducting wires insulating barrier, passes insulating barrier and inner lead connection by the tip that tights a bolt, and makes wiring more convenient rationally.Lightning arrester has the gap in addition, and isolating with system does not at ordinary times have voltage to pass through, and then ageing resistace is better, and lightning arrester occurs can not causing direct short-circuit after the accident, has the ring discharge electrode simultaneously, makes discharge more reliable and more stable.
Description of drawings
Fig. 1 is the profile schematic diagram (band broken section structure) of the utility model embodiment.
Fig. 2 is the structural representation (not containing wire clamp, construction bolt and sparking electrode) of the utility model embodiment.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
In conjunction with Fig. 1, shown in Figure 2, lightning arrester of the present utility model mainly is to be made of assemblings such as wire clamp 1, ring discharge electrode 2, core body 3, insulating cylinder 4, silicon rubber composite sheath 5, construction bolts 6, wherein core body 3 is the columns that are assembled into by top electrode 31, resistor disc 33 and bottom electrode 34 etc., insulating cylinder 4 is enclosed within the outside of core body 3, and coats by the rubber seal sealing.
Silicon rubber composite sheath 5 is the more piece umbrella, adopts disposable sulfidization molding, is embossed in the outside at insulating cylinder and core body top.When making, earlier dry the drying of inner core soma to be reinstalled in the insulating cylinder, then carry out the sulfidization molding silastic material one time.
Ring discharge electrode 2 is enclosed within the outside of silicon rubber composite sheath 5, and it is by bolt, and bolt is screwed on the inner core body, and at this core body position wiring aluminium block 32 and connection bolt 8 is housed, to be communicated with core body inside by wiring aluminium block and connection bolt.And, between connection bolt 8 and insulating cylinder 4 walls, be provided with rubber seal 7 in order to guarantee sealing.
Wire clamp 1 and construction bolt 6 are contained in two of lightning arrester respectively, and wire clamp 1 structure adopts penetration type, can peel off the high-voltage conducting wires insulating barrier like this, passes insulating barrier by the tip that tights a bolt, and can be communicated with inner lead, make wiring more convenient rationally.
Use lightning arrester of the present utility model, when transmission system is struck by lightning, it can be before the circuit breaker action, block power frequency continued flow fast, make the voltage of insulator be clamped at the residual voltage level of lightning arrester, can effectively prevent accidents such as damage to crops caused by thunder broken string and insulator damage, avoid because of circuit breaker action interruption of power supply.The utility model in the use after tested, both satisfied exchanging the requirement of overhead transmission line, satisfied the requirement of AC metal oxide lightning arrester GB11032 and the requirement that polymeric metal oxide surge arrester DL/T815 is used in the transmission line of alternation current again with composite insulator GB/T19519.
Claims (2)
1, a kind of composite sheath formula metal oxide arrester, wire clamp (1) and construction bolt (6) that it includes core body (3) and is positioned at two, it is characterized in that: the outer insulating cylinder (4) that is encapsulated with of described core body (3), insulating cylinder (4) outside is the silicon rubber composite sheath (5) of sulfidization molding once, is arranged with ring discharge electrode (2) on the overcoat (5).
2, composite sheath formula metal oxide arrester as claimed in claim 1 is characterized in that: described wire clamp (1) adopts the penetration type structure.
