Description
Technical field
The present invention relates to a kind of transmission line protective gap device, be specifically related to a kind ofly be applicable to various electric pressure especially super ultra high voltage grade transmission line and can the lightning protection inter space device of segmentation arc extinguishing.
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.Transmission line is struck by lightning, and causes line insulator flashover, and the power frequency continued flow thereupon risen damages insulator string and gold utensil, causes insulator string to burn and blows wire accident.Traditional " blocking type " lightning protection mode, transformation pole tower ground resistance, erection coupling ground wire and lightning conducter, installation leakage conductor etc., due to its limitation, can only solve the lightning strike accident of 50%.In recent years, in order to improve the reliability that transmission line is powered further, power department adopts and installs portable protective gaps in parallel additional to prevent lightning strike accident at transmission line.But in actual motion, it is as follows that portable protective gaps in parallel has obvious defect:
First, portable protective gaps in parallel is arranged on insulator string two ends, is the effect that preferential insulator string punctures when playing thunderbolt of method by shortening insulator string creepage distance.Insulator string creepage distance is by short circuit; not only causing the overall lightning withstand level of power system transmission line to decline makes tripping rate with lightning strike increase; power frequency insulation level when simultaneously causing electric power system normally to run declines, and improves portable protective gaps in parallel and miss breakdown probability between invisible under temporary overvoltage and switching overvoltage.
Secondly, when thunderbolt occurs transmission line, the overvoltage that portable protective gaps in parallel preferentially causes because being struck by lightning and puncturing, leaks into the earth, thus plays the effect of protection transmission line and electric equipment by lightning current.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.
The defect of arc extinguishing ability is not possessed for conventional parallel gap, the patent that inventor is applying for before, 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 signal pickup assembly 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.And for example China Patent No. is the 2011200053246 constraint space jet-stream wind arc extinguishing lightning protection clearance apparatus disclosing for each electric pressure 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, while the gas exhausted material of constraint space inside is sharply heated produce gases at high pressure by high-temperature electric arc, the automatic collection signal of signal pickup assembly also starts gas jet generating means, produce high velocity air instantaneously longitudinally to impact electric arc, be cooled to extinguishing.The patent of applying for before inventor plays a good role for extinguishing power frequency arc, but still some shortcomings: 1. and the connection installation of high-low pressure termination electrode is at insulator string two ends; Because insulator string is arranged on the edge of shaft tower, artificial installs, maintenance difficulties is very high, and easily cause main gap distance not to be inconsistent with set point; In addition gap to play power frequency arc distance insulator string very near, easily burn insulator string and cause at wire clamp place line-outage contingency; 2. before, the device of patent is all one section of arc extinguishing, for 110kV and following electric pressure completely applicable, but 220kV and above, insulator string length is very long, and the ability of one section of arc-control device is effective, easily produces phenomenon of restriking; 3. Patent equipment before is because be arranged on insulator string two ends, and distance aerial condutor is near, can not realize charged with changing operation; 4. one section of arc-control device bullet capacity is less, and service life is short, makes the workload increase of replacing, maintenance.Therefore, above-mentioned device also needs to be further improved, thus reaches better effect, improves the stability of electric power system.
Summary of the invention
The object of the invention is to for the deficiencies in the prior art, provide a kind of overhead transmission line being more applicable to super ultra high voltage grade, successfully can extinguish the power frequency continued flow electric arc that lightning discharge causes and not reduce again electric power system power frequency insulation level, and durable, frequently need not change and can realize carrying out electric arc the lightning protection inter space device of segmentation arc extinguishing.
To achieve these goals, present invention employs following technical scheme:
A kind of different electric pressure segmentation arc extinguishing lightning protection clearance apparatus, comprises arc-control device and is arranged on the portable protective gaps device near insulator string side by side; Portable protective gaps device is formed primarily of low-pressure end electrode and high-pressure side electrode; Wherein, described arc-control device comprises arc extinguishing cylinder and arc extinguishing in the form of annular discs storage magazine I, is provided with trigger winding, trigger electrode, bullet trigger position, arc extinguishing bullet and plane scroll spring in described arc extinguishing storage magazine I; Described trigger electrode one end is connected with trigger winding, and the other end extends to bullet trigger position and is connected with arc extinguishing bullet; Described plane scroll spring is arranged on the center of arc extinguishing storage magazine I; Described arc extinguishing bullet is arranged closely in the storage bullet track of arc extinguishing storage magazine I by the twisting force of plane scroll spring; One end of described low-pressure end electrode is by connecting installation on cross arm of tower, and the other end is arranged in the trigger winding of arc-control device; One end of described high-pressure side electrode is arranged on aerial condutor, and the other end points to low-pressure end electrode.
Arc-control device of the present invention have employed discoid arc extinguishing storage magazine, the bullet that gas carries out arc extinguishing can be produced after can placing a large amount of triggerings, and make arc extinguishing bullet be arranged closely in the storage bullet track of arc extinguishing storage magazine I by the twisting force of plane scroll spring, after the triggering of current arc extinguishing bullet is dropped, next is sent out can enter bullet trigger position automatically, realizes from moving bullet.The deficiency that before overcoming, few, the effective arc extinguishing number of times of arc extinguishing bullet is few, does not need frequently to change arc-control device, reduces the number of times of the upper transmission tower of technical staff, has both decreased manual maintenance workload and cost, and ensured again the personal safety of staff.
Low-pressure end electrode is arranged on cross arm of tower by the present invention, high-pressure side electrode is arranged on aerial condutor, make the preferential insulator string of this device energy breakdown by charge inducing principle and the attracting principle of the charges of different polarity, be that insulator string is not subject to effects of lightning, can not damage because of thunderbolt; And ensure that the voltage endurance capability of power frequency is unaffected, the nothing decreased under switching overvoltage punctures.
In conventional parallel portable protective gaps device; low-field electrode and high-field electrode are arranged on insulator string top and bottom respectively; it also has shortcoming: insulator string is unique solid tie point of wire and shaft tower, subjects the Action of Gravity Field of wire itself, plays an important role to the safety of electrical network.Conventional parallel clearance electrode is installed with on insulator string, adds the stressed of insulator string undoubtedly, and when wind-force makes wire rock swing, this power can be multiplied; High and low pressure termination electrode is then installed on wire and shaft tower by the present invention respectively, does not have a direct impact the stressed of insulator string.
Conventional parallel gap attracts lightning current, protection insulator string, but punctures with thunder and lightning and the power frequency continued flow that rises can through the wire clamp of insulator string (be exactly wire be connected with insulator string that instrument) place and elbow link plate place.The heat of power frequency continued flow can cause wire clamp and conductor overheating, adds the probability of lightning-caused breaking; In the present invention; thunder and lightning punctures from wire toward shaft tower, even if having power frequency arc also can not cause insulator string burn phenomenon, and main protection clearance distance insulator string is far away; the possibility that power frequency arc burns insulator string reduces, better to the protected effect of insulator string.
Further illustrate as of the present invention, the bottom of above-described arc extinguishing cylinder is connected to a striking disk adopting electric conducting material to make.In the present invention; arc extinguishing cylinder adopts non-conducting material to make; such thunder and lightning punctures arc extinguishing cylinder again and then arrives low-pressure end electrode after attracteding to striking disk, this is just equivalent to striking disk and main protection gap is divide into small one and large one two gaps, more can improve arc extinguishing efficiency.And the thunder and lightning of striking disk to around certain air range plays sucking action (insulator string is within its protection range), increases striking ability, thus the main protection clearance distance of device is increased to be equal to or greater than insulator string creepage distance.Suppose that negative polarity thunderbolt is in aerial condutor, lightning wave is sent to close shaft tower insulator string and lightning protection inter space by wire.A large amount of negative electrical charges can be assembled before high-pressure side electrode punctures, by principle of induction known on striking disk by induce the opposite sex positive charge, powerful Coulombic attraction effect can be produced between inducing charge and charge inducing, attract thunder and lightning puncture towards low-pressure end electrode.Positive polarity thunderstorm hour then proving by the same methods.
Further illustrate as of the present invention, this different electric pressure segmentation arc extinguishing lightning protection clearance apparatus also comprises establishes female prolongation arc extinguishing cylinder; The arc extinguishing cylinder bottom of described arc-control device is provided with external screw thread, is threaded with establishing female prolongation arc extinguishing cylinder.Set up more than one prolongation arc extinguishing cylinder, better can adapt to the transmission line of super ultra high voltage grade, in the transmission line of super ultra high voltage grade, insulator string length is longer, and its electric arc puncturing air generation is also just longer, and the ability of one section of arc-control device is effective, easy generation is restriked phenomenon, so set up after extending arc extinguishing cylinder, we just can carry out segmentation arc extinguishing to it, stop phenomenon of restriking to the full extent.
Further illustrate as of the present invention, the bottom of above-described prolongation arc extinguishing cylinder is connected to a striking disk adopting electric conducting material to make.
Further illustrate as of the present invention, the side of above-described prolongation arc extinguishing cylinder is provided with arc extinguishing storage magazine II, is provided with trigger electrode II, bullet trigger position II, arc extinguishing bullet II and plane scroll spring II in arc extinguishing storage magazine II; The trigger winding that magazine I is stored up by wire and arc extinguishing in described trigger electrode II one end is connected, and the other end extends to bullet trigger position II and is connected with arc extinguishing bullet II; Described plane scroll spring II is arranged on the center of arc extinguishing storage magazine II; Described arc extinguishing bullet II is arranged closely in the storage bullet track II of arc extinguishing storage magazine II by the twisting force of plane scroll spring II.Set up the more than one prolongation arc extinguishing cylinder with arc extinguishing storage magazine, better can adapt to the transmission line of super ultra high voltage grade, in the transmission line of super ultra high voltage grade, insulator string length is longer, and its electric arc puncturing air generation is also just longer, and the ability of one section of arc-control device is effective, easy generation is restriked phenomenon, so set up after extending arc extinguishing cylinder, we just can carry out segmentation arc extinguishing to it, stop phenomenon of restriking to the full extent.
Further illustrate as of the present invention, above-described trigger winding is arranged on the center of plane scroll spring, and bullet trigger position is arranged on the side of trigger winding.
The position of trigger winding can prevent and treat according to needs of production in the present invention, can be placed on the marginal position of arc extinguishing storage magazine, also can be placed on plane scroll spring the center that arc extinguishing stores up magazine; Bullet trigger position always arranges the side of trigger winding simultaneously, and arc extinguishing cylinder also adjusts position accordingly, adapts with the position of trigger winding.
Further illustrate as of the present invention, the link of above-described striking disk extends and is deeply embedded in arc extinguishing cylinder.
Further illustrate as of the present invention, the link of above-described striking disk extends and is deeply embedded in and extends in arc extinguishing cylinder.Extend the link of striking disk, and it is inner to be deep into arc extinguishing cylinder, can reduce the size of striking disk like this, and striking effect does not reduce.
The electric power system of super extra-high voltage grade has the features such as the huge and corresponding insulator string length of short circuiting arc is long.Consider that system transmission capacity is huge, working voltage is high, causes portable protective gaps power frequency arc to be difficult to extinguish, and therefore must improve the arc extinction performance of arc extinguishing lightning protection clearance apparatus further.This device increases the arc extinguishing ability of device by the principle that the some arc extinguishing bullets of employing trigger simultaneously.Some arc extinguishing bullets spray action of high-speed airflow in electric arc at the difference of cylindricality long air gap electric arc simultaneously, make electric arc effective deformation and are compressed, and finally extinguish from arc control device ejection.In addition because super ultra high voltage grade insulator string length is long, iff gas jet within the scope of a bit of cast of electric arc one end, power frequency arc is very fast restriking after extinguishing probably.Adopt " can arc control device be extended " for this reason, increase cast arc extinguishing length, make gas more powerful be applied to electric arc, avoid it to restrike.
