Description

A kind of lightning protection constant voltage equipment

Technical field

This utility model is related to barostat field and in particular to a kind of lightning protection constant voltage equipment.

Background technology

Galvanic element can form by the different metal of two kinds of metal activities or by the metal material conductive with other, passes through Produce two electrodes with the chemical back-pressure of electrolyte.Using the difference of the electromotive force of two electrodes, produce potential difference, so that electric Subflow is moved, and produces electric current.It is a kind of electrochemical cell that chemical energy can only be converted to electric energy.Galvanic element is using two electrodes Electrode potential difference, produce electric potential difference so that electronics flowing, produce electric current.Also known as non-accumulator, it is electrochemical cell One kind.Its electrochemical reaction can not reverse, and is chemical energy to be converted to electric energy.It is just briefly again to store up Deposit electric power, relative with accumulator.

Constant pressure source is exactly the regulated power supply that we often say, can guarantee that load（Output current）In the case of variation, keep electricity Pressure is constant.In daily life, constant pressure source is common, and accumulator, aneroid battery are DC constant voltage power supplys, and 220V alternating current, then It is regarded as a kind of AC constant voltage power supply, because their output voltage is basically unchanged, be the size not with output current And significantly change.

Thunder and lightning is a kind of common electric discharge phenomena in nature, and it can destroy building and various industrial or agricultural facility, simultaneously Fire and explosion accident also can be caused.High overvoltage and huge lightning current can be produced during thunder discharge, can not only shoot dead People and animals, also can cleave trees, electric pole etc..Electrostatic induction be thundercloud close to ground when, induce greatly at the top of ground ridge The amount charges of different polarity, after thundercloud with other positions or other thundercloud discharges, ridge loses constraint, and high in the form of lightning wave Speed is propagated and is formed.When lightning protection device accepts thunderbolt, very high electricity is all had on arrester, downlead and grounding body Pressure.Conventional thunder-lightning can be divided into direct striking thunder prevention electricity, anti-induction thunder and lightning and comprehensive thunder-lightning.The lightning arrester one of direct striking thunder prevention electricity As be made up of three parts, i.e. arrester, downlead and grounding body；Arrester is divided into discharging rod, lightning conducter, lighting proof strip again, takes shelter from the thunder Net.Using discharging rod as the thunder-lightning principle of arrester it is：Discharging rod accesses underground by wire, forms isoelectric level with ground Difference, using the height of itself, makes the thunder and lightning cloud electric field that electric field intensity increases to ultimate value be distorted, and starts ionization descending elder generation Lead electric discharge；Discharging rod produces point discharge under forceful electric power field action, forms pilot discharge upwards；Both junctions form thunder and lightning and lead to Road, spews out into the earth therewith, reaches lightning-arrest effect.In fact, discharging rod is attracting thunder needle, the thunder and lightning of surrounding can be attracted and put in advance Electricity, lightning current is transmitted to ground by the earth conductor of itself, it is to avoid protection object is directly struck by lightning.If lightning protection device with The inside and outside electrical equipment of building, electric wiring or other metallic conduit close proximity, will produce electric discharge between them, this Plant phenomenon to be referred to as strikeing back.Counterattack may cause insulation of electrical installation to damage, and metallic conduit burns, or even causes combustible and explosive articles Catch fire and explode.

Utility model content

This utility model aims to provide one kind can be clamped down on metallic conductor electrostatic induction voltage and put with eliminating its electrostatic high-pressure Electrical phenomena, and be capable of for moment high direct voltage being converted into the lightning protection constant voltage equipment that high current is released.

A kind of lightning protection constant voltage equipment described in the utility model, including metal pole I, metal pole II, electrolyte, described gold Belong to pole I, metal pole II is contacted with electrolyte respectively, metal pole I does not contact with metal pole II；Described metal pole I, metal pole II is prepared from for attribute identical metal material.

Described lightning protection constant voltage equipment can be arranged such that：Metal pole I is connected with arrester, and metal pole II is connected with the earth Connect；Or metal pole II is connected with arrester, metal pole I is connected with the earth.

Can also be by arbitrary metal pole of lightning protection constant voltage equipment and the electrical equipment that electrostatic potential or thunder and lightning need to be prevented Connect, another metal pole is connected with the earth, thus playing lightning protection anti electrostatic protective effect.

Described metal pole I is container, and electrolyte holds in a reservoir, and metal pole II is hanging in the electrolytic solution.

Described metal pole I is open-topped container.

Described metal pole II is metal bar, or connects, by the larger metal derby upper end of volume, the knot that metal bar is formed Structure.

The sealant that the upper opening of described metal pole I is made through insulant seals, described metal pole II's Upper end extends out through sealant, and the upper end of metal pole II is furnished with outer terminal.

The arbitrary place in chamber wall upper end of described metal pole I is provided with outer terminal.

Described metal pole I, metal pole II selects high magnetic conduction, high connductivity, high heat conduction, and corrosion resistant alloy material is made.

Preferably, the metal material that described metal pole I, metal pole II adopts is ferroalloy.

A kind of lightning protection constant voltage equipment described in the utility model, its structure is similar with a kind of galvanic element structure devices, and institute is not With the two extremely same or like metal materials of current potential are prepared from, and lead to the electrode that the two poles of the earth metal is formed with electrolyte Potential difference very little.

When static, there is oxidation reaction in the contact surface of electrolyte and two metal electrodes, produce two polarity and current potential phase Same electrode.Because two difference in Electrode Potential are zero, DC constant voltage device is nonpolarity it is impossible to use as battery.

When lightning protection constant voltage equipment two ends sense DC voltage, the electrode tip accepting forward voltage will aggravate its oxidation instead Should, produce a large amount of electronegative ions and flow to this electrode.Accept backward voltage and this current potential is less than the electrode tip of electrode potential, will send out Raw reduction reaction, produces a large amount of positive charged ions and flows to this electrode.So, electric energy is converted into chemical energy, the height of external voltage Be converted to the size of internal current.Meanwhile, this pulse current produces strong magnetic flux change, and in ferrous metal conductor Interior formation is vortexed heat, and thunder energy is converted into chemistry, magnetic and heat energy and discharges, and keeps the electrode potential of itself basic with this Constant, realize pressure-keeping functions.

And can be drawn by the C-V characteristic of lightning protection constant voltage equipment, its dynamic electric resistor very little, and voltage is higher, resistance Less, constant-voltage characteristic is better.

Lightning protection constant voltage equipment described in the utility model has following electrical characteristics：

（1）The quiescent voltage at battery the two poles of the earth is zero；

（2）Dynamic electric resistor very little, and voltage is higher, resistance is less, and constant-voltage characteristic is better；
