Description
Technical field
The utility model relates to a kind of lightning protection arc quenching protection device, has been specifically related to a kind of section of arc formula lightning arrester.
Background technology
Transmission line lightning protection always is the important content of power department Thunder Protection, and lightning fault remains one of key factor affecting power grid security.The impulse flashover that transmission line causes when there is thunderbolt, causes line insulator flashover, then produces very large power frequency continued flow, damages insulator string and gold utensil, causes line accident.Traditional " blocking type " lightning protection mode, due to its limitation, can not solve problem of lightning at all.Therefore power department generally adopts and installs portable protective gaps in parallel or leakage conductor additional to realize protective wire at transmission line.But in actual motion, portable protective gaps in parallel and leakage conductor have its obvious defect as follows:
First, when thunderbolt occurs transmission line, portable protective gaps in parallel preferentially punctures because being struck by lightning the overvoltage that causes, lightning current is leaked into the earth, thus plays the effect of protection transmission line and electric equipment.But there is no arc extinguishing ability due to portable protective gaps in parallel; the power frequency continued flow caused after can not extinguishing insulator string flashover; electric arc is long-time calcination between portable protective gaps; insulator string will be caused to damage; time serious; transmission line may be caused to break, and electric arc can cause ablation to electrode and reduce its protective value simultaneously.Final dependence circuit breaker carrys out extinguish arcs to realize protection transmission line and equipment, is to sacrifice the way that " trip-out rate " and " power supply reliability " exchanges " low rate of failure " for.
Secondly, leakage conductor is expensive, use, maintenance cost is high, Leakage Current is large, and useful life is short, changes frequent, and the zinc oxide module of leakage conductor under lightning impulse owing to there is obvious kelvin effect, easily explode under big current, cause circuit chromic trouble, be unfavorable for electrical network economy, safety, stable operation.
Therefore, people start to study for these problems, as the patent of inventor's earlier application, China Patent No. is 2011201046273 disclose a kind of 10 ~ 35kV overhead transmission line constraint space gas jet arc extinguishing lightning protection clearance apparatus being applicable to 10 ~ 35kV overhead transmission line, this device is installed in parallel in line insulator string two ends, flashover voltage between portable protective gaps is less than protected insulator string, thus had precedence over protected insulator string when transmission line is struck by lightning and puncture, during disruptive discharge, the automatic induced lightening current signal of lightening pulse harvester also triggers high velocity jet gas generating unit, produce high velocity jet air-flow instantaneously to afterflow electric arc longitudinally intense impact in constraint space, be cooled to extinguishing.For another example Chinese Patent Application No. is 2012103715793 disclose a kind of without afterflow electric arc lightning protection inter space protective device, comprises ground side arc-control device, is installed on the ground side gold utensil at line insulator string two ends and side of wire gold utensil respectively by fixture; Ground side arc-control device comprises lightening pulse harvester, insulated enclosure housing, gas generating unit and arcing chamber; The other end of ground side gold utensil is provided with connection tubule; Ground side arc-control device also comprises the tubular earth electrode and L shape earth electrode that use non-metallic conducting material to make, connection is inlayed by the connection tubule on Z-shaped connection gold utensil and ground side gold utensil in one end of L shape earth electrode, the other end of L shape earth electrode through lightening pulse harvester, and is connected with tubular earth electrode; The tubular earth electrode one end of non-metallic conducting material is embedded in arcing chamber, and the other end is connected with insulated enclosure housing.These patents have got good solution effect for the problems referred to above; but the arc-control device work times in these protective devices is limited; be mounted in the normal words sent out area or repeat the more incident coastal area of thunder of thunderbolt; need to change frequently arc-control device; considerably increase maintenance cost; if and increase the work times of arc-control device, the structural design of installing its arc extinguishing storehouse will inevitably increase the weight of arc-control device, is so also unfavorable for Long-Time Service.Therefore inventor is for the feature of the multiple thunder in minefield; lightning protection inter space protective device is improved again; while increasing rupturing duty number of times, alleviate the weight of protective device as far as possible, develop a kind of lightning arrester that can use for a long time, to meet the demand on market.
