The signal acquisition device generates signal after the generation of the arc. The gas generation device is started and therefore generates the airflow capable of blowing out the arc. The invention has the following benefit effects: the device features wide application, light weight, convenient transportation, assembly and disassembly, re-use, lower operation cost as well as environment protection; the device is fast in action, which is able to extinguish the arc quickly and enhance the success rate of recloser; the device is capable of decreasing the trip rate of the transmission line, and protect power facilities, thus being good for the power safety production and improving the power grid reliability.
Description
Technical field
The present invention relates to a kind of lightning protection device, particularly a kind of air blast arc-quenching lightning protection inter space device that is used for each electric pressure transmission line.
Background technology
For transmission line, for fear of causing impulse flashover, cause line insulation to be damaged because of thunder and lightning hits lead, the protection gap is installed in the general employing of electrical production department additional or lightning arrester comes protection circuit.When circuit was struck by lightning, the protection gap leaked into the earth at first because of overvoltage punctures with a large amount of lightning currents, the overvoltage degree is declined to a great extent, thereby play the effect of protection circuit and electric equipment.Its weak point is: the protection gap does not have the arc extinguishing ability, can not turn-off the power frequency continued flow that short circuit causes, can cause circuit breaker trip for phase fault.Can cause the circuit phase-deficient operation for single phase ground fault, make the load tripping operation.Heavy then the electric arc clearance electrode of can ablating causes the gap to lose the protection insulating effect.When not having the insulator arc-over of assemblage gap, electric arc can blow lead and cause that the broken string accident is interrupted supply of electric power if can not extinguish; Leakage conductor costs an arm and a leg, use, maintenance cost height, and leakage current is big, and useful life is short, changes frequently, and blast easily under lightning impulse, be unfavorable for electrical network economy, safe operation.
Summary of the invention
The objective of the invention is to avoid the weak point in the above-mentioned background technology and a kind of air blast arc-quenching lightning protection inter space device is provided.This air blast arc-quenching lightning protection inter space device comprises the wire bond body, the ground connection union body, gas generating unit, signal pickup assembly, high-field electrode, parts such as grounding electrode, the wire bond body is connected respectively on the corresponding electrode with the ground connection union body, and form electrode gap between the corresponding electrode, whole device is by the wire bond body, the ground connection union body is suspended on side by side with insulator string, being used to connect lead and forming reliable wire bond body connection electrode gap one end that is connected with lead is high-field electrode, the ground connection union body that reliably is connected with the ground connection object, being connected to the electrode gap other end is grounding electrode, gas generating unit places near the electrode gap that forms between two electrodes, signal pickup assembly produces the back at electric arc and generates signal, thereby starts the air-flow that gas generating unit produces is enough to blow out electric arc; Gas generating unit is triggered and is moved and produce the arc extinguishing air-flow by being punctured earth current that the back produces with protected insulator electrode gap arranged side by side by lightning voltage.The present invention has following beneficial effect: this device scope of application is wide, is not subjected to the influence of electric pressure, conductor arrangement, insulator type, shaft tower tower, polar effect; Light weight is convenient to transportation, installs, is dismantled; Once mounting can be reused for a long time, and operating cost is low, environmental protection and saving; Be swift in motion, extinguish arcs improves the reclosing success rate fast; Can reduce the transmission line trip-out rate, the protection electric power facility helps electric power safety production, improves electric network reliability.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with embodiment essentiality content of the present invention is described in further detail.
Depend on shown in Figure 1, the lightning protection inter space device of this gas blast arc-quenching comprises parts such as wire bond body 1, ground connection union body 5, gas generating unit 4, signal pickup assembly 6, high-field electrode 2, grounding electrode 3, wire bond body 1 is connected respectively on the corresponding electrode with ground connection union body 5, and form electrode gap 7 between the corresponding electrode, whole device is suspended on insulator string side by side by wire bond body 1, ground connection union body 5.Being used to connect lead and forming the reliable wire bond body that is connected 1 connection electrode gap 7 one ends with lead is high-field electrode 2, the ground connection union body 5 that reliably is connected with the ground connection object, being connected to electrode gap 7 other ends is grounding electrode 3, gas generating unit 4 places near the electrode gap 7 that forms between two electrodes, signal pickup assembly 6 produces the back at electric arc and generates signal, produces the air-flow that is enough to blow out electric arc thereby start gas generating unit 4.Gas generating unit 4 is triggered and is moved and produce the arc extinguishing air-flow by being punctured earth current that the back produces with protected insulator electrode gap 7 arranged side by side by lightning voltage.The distance of electrode gap 7 can be adjusted to adapt to different electric pressures between the electrode.In the practical application, when circuit normally moves, potential difference U between two electrodes
U-dEqual single-phase voltage to earth U
G, do not reach the disruptive critical voltage U of air gap
1, there is not electric arc between two electrodes, can't start gas generating unit 4.If at thunderstorm weather; lightning takes place and hit lead; powerful lightning overvoltage passes to the line insulator string place with the form of ripple by lead; because the dielectric strength of this lightning protection inter space device is lower than the insulation level of protected circuit; protective gap is at first breakdown because of overvoltage; a large amount of lightning currents are leaked into the earth, overvoltage is descended significantly, thereby play the effect of protection circuit and electric equipment.Simultaneously, though the lightning current duration very short (the long 0.5s that impacts, the short only μ s rank of impacting), however amplitude of lightning current is very high, can start gas generating unit 4, and moment produces a large amount of gases and forms air-flow.Because this air-flow has high speed, can produce greatly electric arc and impact, arc temperature is owing to blowing over of air-flow reduced, and the while air-flow has elongated electric arc, makes electric arc can not keep and extinguish, thereby reaches the purpose of extinguish arcs.Impact because the intensity of electrode gap 7 is enough born repeatedly electric arc, gas generating unit 4 also can repeatedly produce high-strength impact gas, so this device can use repeatedly, reaches once mounting, and repeatedly the purpose of Shou Yiing is saved greatly and invested.And the gas that this device produces is safe from harm compliance with environmental protection requirements to biological, environment.
