Background technology
When distribution system because thunderbolt or quadratic effect when higher overvoltage occurring, usually can protect by the discharging gap device, that is: this device is when being subjected to the igniting discharge, produce free electron and ultraviolet light, electromagnetic radiation is to main discharge gap, discharging in the free main channel that forms of excited gas, lightning current is released into ground, thereby release lightning current or power surge electric current; Simultaneously distribution system built-in function overvoltage is played inhibitory action.At present, the structure of such device is in series by single gap or a plurality of single gap.Such device action time is long, the operation voltage height, and can not playing effectively, overvoltage suppresses protective effect.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of superpotential automatic igniting discharging gap device of low-voltage distribution system that is used to suppress is provided, and this device lightning current of both can having released can play inhibitory action to the distribution system internal overvoltage again.
The technical scheme that its technical problem that solves the utility model adopts is: be provided with the N layer; Every layer is provided with main discharge gap and horizontal auxiliary gap, and the horizontal auxiliary gap of each layer vertically forms the main discharge passage of synchronous conducting, and horizontal auxiliary gap and the impedance component that is connected in series with it form the horizontal auxiliary discharge passage of synchronous conducting; In ground floor and the n layer, be provided with outer electrode, they connect the impedance component of left and right two side of each layer respectively with lead; N is 〉=3 natural number.
The utility model has adopted the simultaneous ignition gap has been constituted the simultaneous ignition passage, and the structure by impedance serial connection loop, therefore; the utility model is short operate time; operation voltage is low, can effectively play overvoltage and suppress protective effect, protection low-voltage distribution system operate as normal.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
The utility model is a kind of discharge clearance devices with automatic ignition and protection of overvoltage that is used for low-voltage distribution system, its structure as shown in the figure: be provided with the N layer; Every layer is provided with main discharge gap and horizontal auxiliary gap, and the horizontal auxiliary gap of each layer vertically forms the main discharge passage of synchronous conducting, laterally auxiliary gap and the horizontal auxiliary discharge passage of the synchronous conducting of impedance component 6 formation of serial connection with it; In ground floor and the n layer, be provided with outer electrode 1, they connect the impedance component 6 of left and right two side of each layer respectively with lead 5; N is 〉=3 natural number.
Ground floor is in the n layer, and every layer is provided with 1 horizontal auxiliary gap, and it is formed by 2 transverse electric pole pieces 4.The transverse electric pole piece 4 of each layer is vertically forming the main discharge channel electrode; Laterally, its outer end respectively connects 1 impedance component 6.
The main discharge gap of ground floor and n layer, it is made of electrode slice 2 and intermediate electrode film 3, and the main discharge gap of other layer is made of 2 intermediate electrode films 3.
Above-mentioned main discharge gap, its puncture voltage can be at or about the auxiliary gap puncture voltage.
Operation principle of the present utility model is: when distribution system because thunderbolt or quadratic effect when overvoltage occurring, the free electron and the ultraviolet light that utilize horizontal auxiliary gap to produce, main discharge gap is punctured, overvoltage is suppressed, and the puncture voltage in this gap depends on the size of auxiliary gap puncture voltage.The generation of simultaneous ignition is to utilize by impedance serial connection loop, is produced by the overvoltage that applies itself to form.
