Abstract
The utility model discloses a lightning arrester. The lightning arrester is characterized in that connecting flanges are arranged at both ends of an insulating external sleeve and sleeved with the insulating external sleeve, a resistor core column comprises a core column body which is composed of a plurality of resistance sheets, the resistance sheets are mutually overlapped, position pins are arranged at both ends of the core column body, an insulating fixing layer is arranged around an outer circle, a cover board which is connected with the connecting flange is arrange at one end of the resistor core column, and the cover board is provided with a fixing sleeve. A compressing spring, a connecting sleeve, a fixing seat and a platen are arranged at the other end of the resistor core column in sequence. The connecting sleeve is connected with the fixing seat through screws, a sealing gasket is arranged between the platen and the fixing seat, and the insulating outer sleeve is filled with nitrogen. In case that appearance and size are not changed, the lightning arrester is capable of adjusting the number of the resistance sheets randomly, the lightning arrester with different resistance can be produced fittingly, and an internal electric discharging phenomenon is fundamentally eradicated. Meanwhile, the lightning arrester is simple in structure and convenient to manufacture and assemble. Therefore, manufacturing cost of the lightning arrester is greatly reduced and accordingly production efficiency is improved.
Description
Technical field
The utility model relates to electrical equipment technical field, relates in particular to a kind of lightning arrester.
Background technology
The present employed lightning arrester of power transmission and transformation system, usually formed by insulating coating and resistance stem stem, wherein the resistance stem stem comprises the many groups resistor disc that mutually stacks, one pair of plastic splint or plastics adjustment spacer are set between every two adjacent resistor disc groups, plastic splint installs the location by 4 insulating rods, and fills the nitrogen for insulation between insulating coating and resistance stem stem.This lightning arrester is complex structure not only, member processing and assembling are wasted time and energy, production efficiency is low, and clamping plate, adjustment spacer and insulating rod owing to processing reason or transhipment, assembling process produce easily corner angle or burr or, projection, electric discharge phenomena in use often occur, cause the erosion of burning of each member of lightning arrester, affect the lightning arrester serviceability, severe patient causes the lightning arrester inefficacy to scrap, and also affects thus the normal operation of power equipment, even causes wider security incident.
The utility model content
It is a kind of simple in structure that the utility model provides, and processes easy to assembly fast, can enhance productivity, and reduces labor intensity, and can effectively avoid electric discharge phenomena to occur, and guarantees the use procedure dependable performance, the lightning arrester of long service life.
Realize that the technical scheme that above-mentioned purpose is taked is: a kind of lightning arrester, comprise insulating coating, resistance stem stem and adpting flange, described adpting flange is positioned at the two ends of insulating coating, and be connected with insulating coating suit, described resistance stem stem comprises the stem stem body that is comprised of several resistor discs that mutually stack, the two ends of stem stem body arrange the location pin, outer circumferential sides arranges the insulation fixed bed, the cover plate that one end setting of described resistance stem stem is connected with adpting flange, fixed cover is set on the cover plate, the other end of resistance stem stem sets gradually holddown spring, adapter sleeve, holder and pressing plate, described adapter sleeve is connected with holder by screw, between described pressing plate and the holder sealing gasket is set, is filled with nitrogen in the described insulating coating.
Described insulation fixed bed adopts the impregnation glass wool cloth to be entwined.
Adopt between described adpting flange and the insulating coating that pouring layer is bonding to be connected.
Lightning arrester of the present utility model is by the adjustment of resistance stem stem two end axles pin size, and the in addition effect of holddown spring can be in the situation of profile in conjunction with size constancy, and the quantity of adjusting resistance sheet is suitable for the production of different resistance lightning arresters arbitrarily.This lightning arrester has fundamentally been stopped the internal discharge phenomenon, and simple in structure, and the processing assembling all becomes very easy, the thus manufacturing cost of decrease lightning arrester, and the corresponding production efficiency that improved.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, lightning arrester of the present utility model comprises insulating coating 1, resistance stem stem and two adpting flanges 8,15, two adpting flanges 8,15 are sleeved on the two ends of insulating coating 1, adpting flange 8,15 with insulating coating 1 between adopt pouring layer 14,19 bonding connections.Described resistance stem stem comprises the stem stem body 2 that is comprised of several resistor discs that mutually stack, the two ends of stem stem body 2 arrange location pin 5,17, stem stem body 2 outer circumferential sides arrange insulation fixed bed 3, this insulation fixed bed 3 adopts the impregnation glass wool cloth to be entwined, and is used for the location pin 5,17 at each resistor disc and two ends is adhesively fixed together.The cover plate 16 that one end setting of described resistance stem stem is connected with adpting flange 8 is welded with fixed cover 18 on the cover plate 16, fixed cover 18 cooperates with pin 17, the resistance stem stem is fixed on the axis part of insulating coating 1.The other end of resistance stem stem sets gradually holddown spring 13, adapter sleeve 6, holder 7 and pressing plate 10, and described adapter sleeve 6 is connected with holder 7 by screw 11, and adapter sleeve 6 cooperates with pin 5, and the resistance stem stem is fixed.Described holddown spring 13 is used for the elastic compression of resistance stem stem between adapter sleeve 6 and pin 5, and the adjusting resistance sheet stacks the accumulated error of rear generation thus.Be filled with the nitrogen for insulation in the cavity of described insulating coating 1, and between described pressing plate 10 and holder 7, sealing gasket 9 is set, prevent the leakage of nitrogen, in the cavity of insulating coating 1, be provided with drier 12, be used for the drying of lightning arrester internal structure and nitrogen, guarantee the state of insulation that it is good.Lightning arrester of the present utility model is by the adjustment of resistance stem stem two end axles pin size, and the in addition effect of holddown spring can be in the situation of profile in conjunction with size constancy, and the quantity of adjusting resistance sheet is suitable for the production of different resistance lightning arresters arbitrarily.And because stem stem body 2 is comprised of several resistor discs that mutually stack, its outer circumferential sides arranges insulation fixed bed 3, does not have the multiple member that convex-concave is alternate, mutually be misplaced, thereby has fundamentally stopped the internal discharge phenomenon.And compared with prior art, this lightning arrester structure is simpler, and the processing assembling all becomes very easy, the thus manufacturing cost of decrease lightning arrester, and the corresponding production efficiency that improved.
