Description
Technical field
The utility model has related to a kind of transmission line protective gap device, has been specifically related to a kind of various electric pressures especially super ultra high voltage grade transmission line and lightning protection inter space device that can the segmentation arc extinguishing of being applicable to.
Background technology
The transmission line lightning protection always is the important content of power department Thunder Protection, and lightning fault remains one of key factor affected power grid security.The transmission line lightning strikes, cause the line insulator flashover, and the power frequency continued flow thereupon risen damages insulator string and gold utensil, causes insulator string to burn and blows the wire accident.Traditional " blocking type " lightning protection mode, the transformation pole tower ground resistance, set up coupling ground wire and lightning conducter, installation leakage conductor etc., due to its limitation, can only solve 50% lightning strike accident.In recent years, in order further to improve the reliability of transmission line power supply, the power department employing is installed protection in parallel gap additional at transmission line and is prevented lightning strike accident.Yet, in actual motion, it is as follows that protection in parallel gap has obvious defect:
At first, protection in parallel gap is arranged on the insulator string two ends, is that the method by shortening the insulator string creepage distance plays the effect that while being struck by lightning, preferential insulator string punctures.The insulator string creepage distance is by short circuit; not only causing the whole lightning withstand level of power system transmission line to descend increases tripping rate with lightning strike; power frequency insulation level while simultaneously causing electric power system normally to move descends, and has improved protection in parallel gap mistakenly hit under temporary overvoltage and switching overvoltage between invisible to wear probability.
Secondly, when the transmission line lightning strikes, protection in parallel gap, preferentially because the overvoltage that thunderbolt causes punctures, leaks into the earth by lightning current, thereby plays the effect of protection transmission line and electric equipment.Yet because parallel connection protection gap does not have the arc extinguishing ability; can not extinguish the power frequency continued flow caused after the insulator string flashover; electric arc is long-time calcination between the protection gap; to cause insulator string to damage; when serious; may cause the transmission line broken string, electric arc can cause ablation and reduce its protective value electrode simultaneously.The final circuit breaker that relies on comes extinguish arcs to realize protecting 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 that does not possess the arc extinguishing ability for common parallel connection gaps, the inventor is in the patent of applying for before, China Patent No. is 2011201046273 to disclose a kind of 10～35kV overhead transmission line constraint space gas jet arc extinguishing lightning protection clearance apparatus that is applicable to 10～35kV overhead transmission line, this device is installed in parallel in the line insulator string two ends, flashover voltage between the protection gap is less than protected insulator string, thereby having precedence over protected insulator string when transmission line is struck by lightning punctures, during disruptive discharge, the automatic induction lightening stream signal of signal pickup assembly also triggers the high velocity jet gas generating unit, moment produces the high velocity jet air-flow to the intense impact longitudinally of afterflow electric arc in constraint space, be cooled to and extinguish.And for example China Patent No. is 2011200053246 to disclose the constraint space jet-stream wind arc extinguishing lightning protection clearance apparatus for each electric pressure transmission line, this device is installed in parallel in the line insulator string two ends, flashover voltage between the protection gap is less than protected insulator string, thereby having precedence over protected insulator string when transmission line is struck by lightning punctures, during disruptive discharge, when the gas exhausted material of constraint space inside is sharply heated the generation gases at high pressure by high-temperature electric arc, the automatic collection signal of signal pickup assembly also starts the gas jet generating means, moment produces high velocity air and longitudinally electric arc is impacted, be cooled to and extinguish.The patent of application plays a good role for extinguishing power frequency arc before the inventor, but some shortcomings still: 1. and the connection installation of high-low pressure termination electrode is at the 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 the main gap distance not to be inconsistent with set point; Power frequency arc that rise in gap is very near apart from insulator string in addition, easily burns insulator string and causes the broken string accident at the wire clamp place; 2. the device of patent is all one section arc extinguishing before, fully applicable for 110kV and following electric pressure, but 220kV and above, insulator string length is very long, and the ability of one section arc-control device is effective, easily produces the phenomenon of restriking; 3. Patent equipment is because be arranged on the insulator string two ends, near apart from aerial condutor before, can not realize charged with changing operation; 4. one section arc-control device bullet capacity is less, and service life is short, and the workload of changing, safeguarding is increased.Therefore, above-mentioned device also needs to be further improved, thereby reaches better effect, improves the stability of electric power system.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, a kind of overhead transmission line that more is applicable to super ultra high voltage grade is provided, can successfully 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, need not frequently change and can realize electric arc is carried out the lightning protection inter space device of segmentation arc extinguishing.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of different electric pressure segmentation arc extinguishing lightning protection clearance apparatus, comprise arc-control device and be arranged on side by side near the protection inter space device of insulator string; The protection inter space device mainly consists of low-pressure end electrode and high-pressure side electrode; Wherein, described arc-control device comprises arc extinguishing cylinder and arc extinguishing storage magazine I in the form of annular discs, in described arc extinguishing storage magazine I, is provided with trigger winding, trigger electrode, bullet trigger position, arc extinguishing bullet and plane scroll spring; Described trigger electrode one end is connected with trigger winding, and the other end extends to the bullet trigger position and is connected with the arc extinguishing bullet; Described plane scroll spring is arranged on the center of arc extinguishing storage magazine I; Described arc extinguishing bullet stores up in the storage bullet track of magazine I by the twisting force close-packed arrays of plane scroll spring at arc extinguishing; 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 the low-pressure end electrode.
