It connects the lower end of spray point and draws the upper end of lower beam.
Spray point is process by round stainless steel material, and upper end is needle point top, and lower end is provided with an end face, is discharged
Needle lower end and draw lower beam and discharging gap insulator and form a air gap, it may be assumed that discharging gap.Discharging gap insulator one end
It can be screwed on spray point.Spray point is integrated with protective cover electrical connection simultaneously.
Protective cover is process using stainless steel material.Protective cover is connect with spray point, exhausted by protective cover with lower beam is drawn
Edge insulating sublayer.It is provided with capacitance group string and discharging gap insulator in protective cover, spray point, discharging gap insulator and draws lower beam
The discharging gap of composition also is located in protective cover.Silica gel can be used in protective cover by all device encapsulatings and is not in leak adhesive.
The capacitor array that capacitance group string is made of several nonpolarity high pressure resistant capacitors of large capacity.Capacitance group string one end with put
Acusector is connected, the other end is connected with lower beam is drawn.Capacitance group string surrounds spray point, draws lower beam and discharging gap insulator composition
Discharging gap around be uniformly distributed, while by conservation cover wrap up protect.Capacitance group string includes left capacitance group string (by three or more
Capacitor is connected in series) and right capacitance group string (being connected in series by three or more capacitors), left capacitance group string and right capacitance group string difference
Positioned at the left and right side of discharging gap insulator.The upper end of left capacitance group string is connected with spray point, lower end and draws lower beam phase
Connection, the upper end of right capacitance group string is connected with spray point, lower end is connected with lower beam is drawn.
Discharging gap insulator is process by insulating materials, is upper and lower opening, middle part is empty cylindrical barrel, barrel
Partial centre is also empty.Spray point lower end is fixed in discharging gap insulator one end, the other end is fixed on and draws lower beam upper end.It puts
The air for being formed and being discharged between lower beam upper surface, discharging gap insulator medial surface by high-voltage breakdown is drawn in acusector lower end surface

Effect.Draw lower beam upper end to be equipped with for fixing the stationary plane one of discharging gap insulator and for fixing with protective cover insulator
Stationary plane two.Draw lower beam lower end to be equipped with for the ring flange fixed with tower or building.
When the arrester in the utility model is installed on by protection building, there are when thundercloud above arrester,
Can be known by electromagnetism sense principle will will form charge inducing on arrester, and opposite with thundercloud polarity.Due to spray point and under drawing
Bar be mutually insulated and by capacitance group string be connected, thus arrester draw lower beam upper end will form it is opposite polarity with thundercloud
Charge is connected because drawing lower beam with the lower end of capacitance group string, the lower pole of capacitance group string can there are with the opposite polarity electricity of thundercloud
Lotus is to capacitor charging, and the upper end of capacitance group string will will form charge identical with thundercloud polarity and the quantity of electric charge will be with capacitance group string
Lower end is identical.Therefore the tip of spray point will will appear and the opposite polarity charge of thundercloud.When air is by thundercloud disruptive discharge,
Thundercloud discharge electric current will connect sudden strain of a muscle by the spray point in arrester first, then charge to capacitance group string, when capacitance group string is charged to one
When constant voltage, discharging gap breakdown will discharge, and electric current by disruptive discharge needle and draws the electric discharge between lower beam from spray point
Gap, which reaches, draws lower beam, completes entirely to flash journey to connecing for thunder and lightning to flow into the earth by downlead.
During connecing sudden strain of a muscle, after thundercloud guide first reaches spray point point neutralization needle point charge, charge with being formed to capacitance group string
The charging current of capacitor, rather than direct leakage current over the ground.Capacitance current be compared to leakage current over the ground have it is shorter
Path, the not no impedance phase of downlead, thus be compared to common arrester and have bigger leader current, it is more easier to generate first
Electrical conduction current.Pilot discharge will discharge over the ground to capacitor charging compared to common arrester when connecing sudden strain of a muscle, reduce under arrester draws
Body and the route induction reactance and impedance for connecing the sudden strain of a muscle body of rod, so that electric discharge guide is more prone to produce.The utility model arrester overcomes
Arrester downlead is too long, and downlead line impedance is excessive and discharge time for being formed is slow, disadvantage that discharge voltage is high.Yin Ben is real
It being reduced with novel middle arrester lightning rod discharge voltage, discharge time accelerates, thus increase the conservation radius of arrester, so that
Arrester has bigger lightning protected range.
Spray point has a tip, when there are feel to accumulate at its tip by electromagnetism when thundercloud for arrester upper end
Accordingly with the opposite polarity charge of thundercloud, simultaneously because point discharge effect, tip charge will be ionized and be formed with thundercloud
Discharge guide, and thunder and lightning is formed and is guided.Neighbouring thundercloud is directed on needle point and is discharged.
Protective cover has a hollow cavity, for placing capacitance group string, while can be by spray point lower end and under drawing
Bar upper end etc. is fixed in cavity.Play support and fixed effect.Protection is played to components such as the intracorporal capacitance group strings of chamber simultaneously
Effect, protects the intracorporal component of chamber not by the destruction of external strength, and be affected by the intracorporal component of chamber not.
Capacitance group string is formed in series and parallel using one group of capacitor, is connected to spray point and is drawn between lower beam.It is first when thundercloud discharge
It charges to it, so that thundercloud is faster to periphery object discharge.Simultaneously when thundercloud does not discharge, accumulation storage is played to charge
Effect.
Discharging gap, which has insulated, to be process using insulating materials, plays a part of to support to electric discharge needle point, while being played pair
Electric discharge needle point and draw the connection function of lower beam, electric discharge needle point and lower beam will be drawn be dielectrically separated to form discharging gap.Discharging gap exists
When capacitance group string is charged to certain voltage in discharging gap will ignition discharge, protective effect is stringed together to capacitance group.
Protective cover insulator is process using insulating materials, to protective cover and draws lower beam connection and supporting role, right
Component in protective cover shields and is sealed processing to protective cover, at the same by protective cover with to draw lower beam mutually exhausted
Edge.
Draw the support that lower beam plays all components of arrester, while insulating subgroup with spray point and discharging gap
At discharging gap.Drawing the design of lower beam lower part has mounting flange, for entire arrester to be fixedly mounted.
The utility model overcomes the deficiencies in the prior art, provide it is a kind of can equivalent the earth absorb guide connect sudden strain of a muscle
Device, simple and compact for structure, lightning protection fruit effect is good, effectively quickly thundercloud can be guided to discharge over the ground, easy to install and use, peace
It is complete reliable, it can be widely applied to protect direct stroke the occasions such as equipment, people, buildings, spacious environment.
