Abstract
A patch board with an internally arranged three-pole discharge tube lightning protection device comprises a patch board shell and a patch board circuit. The three-pole discharge tube lightning protection device is installed in the patch board circuit, when the voltage in the circuit reaches a three-pole discharge tube threshold value due to the lightning induction or other reasons, a three-pole discharge tube is conducted, an electric current is released to a ground wire, and therefore the lightning protection purpose can be achieved. Further, the three-pole discharge tube is provided with three pins, one pin is connected with a fire wire, one pin is connected with a zero wire, and the other pin is connected with the ground wire; no matter overvoltage and overcurrent are introduced from the zero wire or the fire wire, the three-pole discharge tube can release the overvoltage and the overcurrent to the ground wire to achieve the lightning protection purpose, and therefore the electrical safety of the patch board is improved; meanwhile, the patch board with the internally arranged three-pole discharge tube lightning protection device is simple in structure and low in production cost, and can meet the popular demands.
Description
Technical field
The present invention relates to a kind of wiring board of improvement.
Background technology
Wiring board is the articles for daily use often used in life, that various power consumption equipment is powered requisite equipment, the wiring board that common wiring board in life is powered based on single function, most wiring board does not have the function of lightning protection, and the Special lightning protection patch board on market is complicated, expensive, ordinary people requirement can not be met, for this reason, the invention provides a kind of simplicity of design, the lightning protection wiring board of low production cost, to meet ordinary people demand.
Summary of the invention
It is simple that technical problem to be solved by this invention is to provide a kind of structure, and the lightning protection wiring board of low production cost, to meet ordinary people demand.
The present invention is achieved through the following technical solutions: a kind of wiring board of built-in electrode surge arrester lightning protection device, comprise wiring board shell, wiring board circuit, in described wiring board circuit, electrode surge arrester lightning protection device is installed, because of when in lightning induction or other reason circuit, voltage reaches electrode surge arrester threshold values, electrode surge arrester conducting, electric current is discharged into ground wire, thus reaches the object of lightning protection.
Further, described electrode surge arrester has three pins, and a pin connects live wire, a pin connects zero line, and another one pin connects ground wire, like this, no matter overvoltage electric current introduces from zero line, or introduce from live wire, and electrode surge arrester can be discharged into ground wire.
The invention has the beneficial effects as follows: wiring board of the present invention, in wiring board circuit, electrode surge arrester is installed, because of when in lightning induction or other reason circuit, voltage reaches electrode surge arrester threshold values, electrode surge arrester conducting, electric current is discharged into ground wire, thus reach the object of lightning protection, improve wiring board electrical safety, meanwhile, patch board provided by the invention is simple, production cost is comparatively cheap, can meet public demand.
Accompanying drawing explanation
For ease of illustrating, the present invention is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is common wiring board circuit theory schematic diagram.
Fig. 2 is circuit theory schematic diagram of the present invention.
Embodiment
With reference to shown in Fig. 1, common wiring board circuit theory schematic diagram, live wire connects wiring board switch, connect two jacks respectively again, a jack of Three-hole socket connects ground wire grounded, and a jack connects live wire, another hole connects zero line, two spring hole scoket one jacks connect live wire, and another jack connects zero line, does not connect ground wire.
With reference to shown in Fig. 2, the wiring board circuit theory schematic diagram of a kind of built-in electrode surge arrester lightning protection device of the present invention, it has installed electrode surge arrester on common wiring board circuit base, electrode surge arrester has three pins, a pin connects live wire, a pin connects zero line, and another one pin connects ground wire.No matter overvoltage electric current introduces from zero line, or introduce from live wire, as long as when in circuit, voltage reaches electrode surge arrester threshold values, electrode surge arrester all can conducting, and electric current is released to ground wire, thus reaches the object of lightning protection, improves wiring board electrical safety.
With reference to shown in Fig. 2, from structure, in fact electrode surge arrester can be regarded as and is made up of a pair of two pole discharge tube, when temporary overvoltage acts on live wire or zero line, if wherein first a pole discharge, then the free electron now produced by gas ionization at tube interior can cause ionization by impact at another pole interpolar rapidly, is discharged very soon in another pole, like this, electrode surge arrester can also play the object of release current in advance.
Meanwhile, patch board provided by the invention is simple, and production cost is comparatively cheap, can meet public demand.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of obtaining without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection range that protection scope of the present invention should limit with claims is as the criterion.
