Description
Technical field
The present invention relates to arrester field more particularly to a kind of Penetrative lightning arresters.
Background technology
Low-voltage distributing line is the level-one power supply system of closer user in electric system, be responsible for industrial and agricultural production,
The important duty of resident's daily life power supply has the characteristics that line construction is complicated, circuit total amount is more, area coverage is wide.It crosses
It goes long-term existence to focus on the thought of the light distribution of major network, leads to status of equipment, technical merit of current distribution etc. and major network phase
Than there is larger gaps.Distribution line dielectric level is relatively low at present, and lightning protection measures are single, compared to ultra-high-tension power transmission line at
Ripe lightning-protecting engineering, distribution line is easier that lightning stroke flashover tripping occurs, to seriously affect power supply reliability.
With the raising of China 10kV Distribution Network Frame hollow wires insulation rate, insulated conductor breakage caused by lightning stroke problem is increasingly prominent
Go out, great threat is constituted to operation of power networks and personal safety.Installation Transmission Line Arrestor is that a kind of effective lightning protection is arranged
It applies, it discharges thunder energy by non-linear resistor, inhibits the power frequency continued flow starting the arc, protects insulator that flashover does not occur, and
Prevent insulated conductor breakage caused by lightning stroke.Therefore, Transmission Line Arrestor is gradually extensively using in distribution line.
Currently, in 10kV power distribution networks external series gap Penetrative lightning arrester use it is commonplace.Such as publication number
CN201420450567.4 discloses a kind of protection insulated conductor band external series gap Penetrative lightning arrester, can effectively prevent aerial exhausted
The lightning-caused breaking of edge conducting wire.But it is disclosed to exist in the prior art many problems, such as：One, external series gap is atmospheric environment, but just
Under normal operating voltage, deterioration is generated since valve block bears power-frequency voltage effect for a long time, causes its C-V characteristic to generate variation, leads
The increase of the leakage current of valve block is flowed through in cause.Resistive component in electric current sharply increases, and can make temperature rise on valve block and occur
Thermal runaway when serious, or even causes the explosion accident of arrester；Two, the design of open type can not avoid electric arc to distribution line
Influence, be easily damaged insulator when power frequency continued flow electric arc drifts about towards insulator direction；Three, the design structure of open type makes
The discharge component of arrester and draw electrical components and be exposed in oxygen, gradually aoxidizes, lightning-arrest effect slowly fails very much；Four, outer room
Gap exposes in air, since the humidity in air changes with the variation of environment, leads to its electric conductivity under different humidity
Can also can be different, seriously affect the lightning-arrest effect of arrester；Five, the discharge part for drawing electric position and electrical verification ring of arrester at present
Position all uses ellipsoid to design, and can also have a greatly reduced quality in lightning-arrest effect.
Invention content
The present invention for existing external series gap Penetrative lightning arrester design in arrester resistor disc easily influenced by power-frequency voltage, work
Frequency afterflow electric arc eliminates without effective means, electric discharge position and draws that electric position is oxidizable and it constructs unreasonable problem and outer room
Gap arrester series of technical easily affected by environment etc., provide a kind of Penetrative lightning arrester.
The purpose of the present invention is to provide a kind of Penetrative lightning arresters, to solve the above technical problems.
The present invention using following technical scheme in order to solve the above technical problems, realized：
A kind of Penetrative lightning arrester, the puncture arrester puncture electrical verification mechanism by high pressure, column, arrester, consolidate
Determine pedestal and is sequentially connected composition from top to bottom；It includes electric discharge position that the high pressure, which punctures electrical verification mechanism, and electric discharge position is plugged in column
The inside of shape body；The column lower end includes cylinder；The arrester and cylinder are bolted by first；It is described to keep away
Thunder device includes drawing electric position, draws electric position and is connected to arrester upper end and plugs the inside into column；It is envelope inside column
The chamber closed is filled with inert gas by inflation port；The electric discharge position is pyramidal structure with electric position is drawn；Described consolidates
Determine pedestal to connect with the earth by ground wire.
Since external series gap uses hermetic design, it is filled with inert gas in closed chamber, under 10kV power-frequency voltages,
Due to the stability of inert gas, the resistor disc of arrester will not be influenced by power-frequency voltage, and resistor disc C-V characteristic will not become
Change, to ensure that the stability of arrester；When by effects of lightning, it can puncture in cavity under the action of high voltage of thunder and lightning
Inert gas, arrester can be very good energy introducing the earth, and the power frequency continued flow electric arc then generated can be very good to inhibit
In cavity, fire hazard will not be generated because of insulator, the wire insulation around the electric arc influence of generation；Additionally, due to cavity
Inside not oxygenous and discharge component and draws electrical components and use tip design, using the principle of point discharge, discharge component and draw electricity
Component not will produce oxidation and take shelter from the thunder better.
Preferably, the high pressure puncture electrical verification mechanism include puncture tooth, pierce through folder lid, striking electricity ring, discharge position and
Plastic housing.
Preferably, the arrester is metal zinc oxide lightning arrester.
Preferably, the puncture tooth is pyramidal structure, and one layer of insulation silicone grease of surface smear can prevent puncturing structure shadow
