Technical field
It the utility model is related to arrester technical field, more particularly to a kind of arrester of built-in inductance coil.
Background technology
Relative to voltage levels power transmission network, power distribution network dielectric level is low, power distribution network accident caused by lightning surge
Probability is higher.In order to increase power supply reliability, power distribution network typically uses neutral non-effective grounding mode, and this also brings power distribution network
The problem of overvoltage level is higher, the distribution transformer insulation breakdown caused by thunder and lightning, positive and negative conversion overvoltage often occurs, it is high
Pressure fuse frequently fuses, the accident such as arrester damage.
Transformer is mainly that positive and negative conversion overvoltage causes by lightning damage.Nomal transformation overvoltage is lightning surge
Along low-voltage circuit invasion distribution transformer low-pressure side, the overvoltage in low pressure winding is produced by electromagnetic coupled on high pressure winding
Higher overvoltage, cause high-voltage isulation punch through damage.Inverse transformation overvoltage shows as lightning wave and passes to transformation along high-tension line
Device head end, high-pressure side lightning arrestor movement, thunder and lightning flows through arrester and earthing or grounding means enters ground, due to the arrester of transformer, shell,
Low pressure neutral point using 3 points of totally one ground the mode of connection, lightning current can grounded resistance make low pressure neutral point potential lifting, connect
Overvoltage is presented in ground body, and the overvoltage overwhelming majority is added in low pressure winding；By inverse transformation process, high pressure winding will appear from feeling
Voltage is answered, because now high-pressure side lightning arrestor movement, high-pressure side winding terminal current potential are fixed by residual voltage of arrester, overvoltage
Voltage is along high voltage winding component cloth.The current potential highest at the neutral point of high-pressure side, may puncture insulation near neutral point or winding is exhausted
Edge.
It follows that although controller switching equipment employs arrester, protective effect is served for fraction thunder and lightning, but not
It can avoid distribution transformer that overvoltage occurs completely, reduce accident.
Utility model content
The deficiency for more than, the utility model provide a kind of arrester of built-in inductance coil, it is steep can to suppress lightning current
Ripple and controller switching equipment is avoided to suffer lightning damage.

Include inductance coil, the inductance coil between the resistor valve sheet and the Top electrode, and with the resistor valve sheet
It is connected with Top electrode.
In use, Top electrode is connected with high-pressure side, i.e., Top electrode is on high-tension side electrode.When lightning current enters arrester
When, inductance coil is first passed through, the characteristic that the suppression electric current having using inductance coil can not be mutated, suppresses lightning current steep wave and drop
Low amplitude of lightning current, then absorb thunder and lightning stream energy with entering through resistor valve sheet, effectively suppress the overvoltage of grounding body, so as to reach suppression
Lightning current steep wave processed and the purpose for avoiding controller switching equipment from suffering lightning damage.
On the basis of above-mentioned technical proposal, the utility model also has further optimization and improved.
Further, arrester provided by the utility model also includes spring, and the spring is located at the resistor valve sheet
Between the inductance coil.Spring can apply pressure to resistor valve sheet and inductance coil, play a part of a kind of compression, ensure
Resistor valve sheet, inductance coil and interelectrode effectively connection.

Filling epoxy resin can play a part of sealing, isolation.
Preferably, the resistor valve sheet is ZnO resistors valve block.
Compared with prior art, the beneficial effects of the utility model are：Arrester provided by the utility model by using
The characteristic that the suppression electric current that inductance coil has can not be mutated, installs inductance coil additional inside conventional arrester, passes through inductor wire
Circle reduces the electric current for flowing through arrester and high-voltage line trackside, so as to reduce the electric current for flowing through grounding resistance, suppresses grounding resistance electricity
Lifting is pressed, avoids the infringement of the controller switching equipment caused by positive and negative conversion overvoltage, and then avoids controller switching equipment by broken by lightning.
