Description
Technical field
The utility model relates to lightning protection field, is related specifically to a kind of discharger for high-voltage large current.
Background technology
Thunder damages it mainly through two kinds of forms, and one is that thunder directly hits, on building, thermal effect effect and electrodynamic action occurs; Two is secondary actions of thunder and lightning, i.e. the electrostatic induction that produces of lightning current and electromagnetic induction.
The mode of what we saw usually release electric power facility thunder and lightning is that the simple lightning protection device of one forming portable protective gaps by two metal electrodes is comparatively general.One of them electrode is fixing, and connect with live wire, another electrode is connected with earthing device by auxiliary gap on the insulator, keeps the clearance distance specified between two electrodes.Portable protective gaps simple structure, easy to maintenance, but its arc extinguishing ability is poor voluntarily.
Limited for common lightning discharger derivative in the field of lightning protection lightning current of mostly releasing above, some does not reach the standard of safety-security area, part also have high energy thunder amplification discharger ability but small product size is larger.For lightning discharger; it is the first critical point of all power consumption equipment lightning protections; if it is released, lightning current is limited; damage will be caused to rear class lightning protection device; thus the power consumption equipment extending to rear class lacks enough safeguard protections; expensive device will be likely caused to be ruined, even whole system collapse.Along with the rise of electric equipment and the electronic equipment to voltage-sensitive, also more and more higher to the requirement of lightning protection.And the most volume of lightning discharger is on the market comparatively large, lightning current of releasing is reliable not, and stability is not ideal enough.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of compact high-performance lightning discharger, its compact conformation, and volume is little, good reliability, and thunder and lightning of releasing is stablized.
Be achieved through the following technical solutions above-mentioned purpose:
A kind of compact high-performance lightning discharger, comprise discharge cavity, be arranged at electrode in discharge cavity and arc-extinguishing plate, arc-extinguishing plate and electrode are connected with the firing circuit be arranged at outside discharge cavity respectively, described discharge cavity comprises the insulation inner chamber that is placed in the hollow cylinder shape of its inside, one end in described insulation inner chamber arranges two electrodes forming ladder type gap, and the other end arranges an arc-extinguishing plate relative with described gap; Described firing circuit is integrated in one with on the arc-shaped circuit board coordinated outside discharge cavity, and described arc-shaped circuit board and described discharge cavity are arranged side by side.
In above-described a kind of compact high-performance lightning discharger, preferably: described discharge cavity also comprises the Wiring button of a pair symmetry be connected with described electrode and arc-extinguishing plate.
In above-described a kind of compact high-performance lightning discharger, preferably: described insulation inner chamber, Wiring button and arc-shaped circuit board are arranged in a flat T shape shell jointly.
In above-described a kind of compact high-performance lightning discharger, preferably: described insulation inner chamber is insulated by an insulation board and described discharge cavity.
The beneficial effects of the utility model are: 1. during ladder type gap discharge; electric arc can move up rapidly along below and be elongated; draw together large discharge space; when lightning current reduces by guiding lightning current by arc-extinguishing plate arc extinguishing voluntarily; gap can not serious burn; guarantee that there is good fail safe, be therefore more suitable for the lightning protection of distribution line and controller switching equipment.Under normal circumstances; discharging gap is insulation; and dielectric strength is higher than the normal operating level of institute's protection circuit; therefore; when circuit is struck by lightning, portable protective gaps is first breakdown because of overvoltage, is released by a large amount of lightning current; overvoltage is significantly declined, thus plays the effect of protection circuit and electric equipment.2. be a kind of one pole, voltage switch type high energy surge protector, insulation inner chamber surge relieving capacity is large, and voltage protection level is low, fast response time, and afterflow is little.3. inner adopt exquisite discharging gap closed structure, at utmost decrease stained to discharging gap of the injection of discharge spark and environment.4. the specific alloy material precision of discharging gap arc ablation resistance excellent performance is made, when gap voltage is no more than maximum continuous operating voltage, due to the effect of electric clearance, in high-impedance state between electrode; When voltage exceedes ignition voltage, gap is breakdown, occurs arc discharge, and surge energy discharges; Meanwhile, electrical discharge arc crashes by arc-extinguishing plate, reduces afterflow; After afterflow is cut off completely, discharging gap returns to high-impedance state again.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is described in further detail, it should be noted that, the direction term mentioned in following examples, such as " upper and lower, left and right " are only the directions with reference to accompanying drawing, therefore, the direction term of use is used to illustrate and is not used for limiting the utility model.
As Figure 1-4, a kind of compact high-performance lightning discharger, entirety comprises the module of discharge portion and the module of circuit part, both combine by compact space structure the space that whole discharger is taken and reduce, comprise discharge cavity 8, be arranged at the electrode 4 in discharge cavity 8 and arc-extinguishing plate 3, arc-extinguishing plate 3 is connected 7 with the firing circuit be arranged at outside discharge cavity 8 respectively with electrode 4, and this structure, discharge cavity 8 comprises the insulation inner chamber 5 that is placed in the hollow cylinder shape of its inside, one end in described insulation inner chamber 5 arranges two electrodes 4 forming ladder type gap, therefore the discharger discharge energy that forms of firing circuit 7 and discharge cavity 8 is large, the other end arranges an arc-extinguishing plate 3 relative with described ladder type gap, described firing circuit 7 is integrated in one with on the arc-shaped circuit board coordinated outside discharge cavity 8, and described arc-shaped circuit board and described discharge cavity 8 are arranged side by side.Be connected to the electrode 4 inside insulation inner chamber 5 and arc-extinguishing plate 3, be connected with firing circuit by Wiring button 1, firing circuit 7 is in parallel with the discharger that discharge cavity 8 forms to be located in the inner chamber formed by the shell 6 of plastics jointly.
In above-described a kind of compact high-performance lightning discharger, preferably: described discharge cavity 8 also comprises the Wiring button 1 of a pair symmetry be connected with described electrode 4 and arc-extinguishing plate 3.
In above-described a kind of compact high-performance lightning discharger, preferably: described insulation inner chamber 5, Wiring button 1 and arc-shaped circuit board are arranged in a flat T shape shell 6 jointly, this shell 6 inner flat, take up room little, whole module is carried and installs all quite convenient, the symmetrical shape of shell 6, easy to use.
In above-described a kind of compact high-performance lightning discharger, preferably: described insulation inner chamber 5 is insulated with described discharge cavity 8 by an insulation board 2.
