Background technology
The insulated overhead line overwhelming majority suffers indirect lightning strike, when the lightning overvoltage flashover, because overvoltage protection device is parallelly connected with line insulator; The high potential that lightning current causes makes the series gap action of overvoltage protection device, has reduced the potential difference of tower arm and lead, guarantees no longer flashover of insulator; Thereby avoided the line tripping power failure; In order to guarantee the operate as normal of overvoltage protection device, the clearance distance between the outer sparking electrode of necessary assurance is in the scope of regulation, and spacer ring of the prior art is processed by spring stainless steel wire integral body; Have following problem in the design: 1. processing is relatively had any problem; 2. because the wind rotation is moving, can not prevent that spacer ring from moving, and the gap between insulator and the spacer ring can not guarantee uniformity.
Summary of the invention
The purpose of the utility model is to overcome the defective of prior art, proposes a kind of fixing circuit fixed interval (FI) overvoltage protection device structure of clearance distance between sparking electrode that satisfies.
The technical solution of the utility model: its structure is to comprise tape insulation lead lightning arrester; Tape insulation lead lightning arrester connects with 10kV insulated overhead line customary insulation, circuit cross-arm through the anti-slip mounting bracket; Tape insulation lead lightning arrester connects with the 10kV insulated conductor through puncture larynx hoop; Composite insulator is installed in tape insulation lead lightning arrester bottom; Be equiped with right sparking electrode base between tape insulation lead lightning arrester and the composite insulator, right sparking electrode connects with right sparking electrode bolt of lower base, installs left sparking electrode in anti-slip support middle and lower part.
The advantage of the utility model: the discharging gap fixed distance is exempted from adjustment, guarantees two electrode lightning discharge stable performances.Because sparking electrode adopts the circular cone spherical structure, the sensitiveness that can guarantee the acute angle discharge can guarantee reliability and the multiple discharge not burning of discharging, sparking electrode employing austenitic stainless steel material, good weatherability, anticorrosion again.This product weight is light, simple in structure, attractive in appearance, practical, easy for installation, non-maintaining.
Description of drawings
Accompanying drawing 1 is the structural representation of circuit fixed interval (FI) overvoltage protection device.
