Description
Technical field
The utility model relates to line overvoltage protection device production field, specifically provides a kind of composite type lightning protection line overvoltage protection device.
Background technology
The lightning protection line overvoltage protection device of prior art is formed primarily of lightning arrester body, lightning arrester drainage ball, wire drainage ball and connecting struts plate.Lightning arrester body bottom is fixed on connecting struts plate one end, and the connecting struts plate other end is fixed on insulator lower end and is connected with circuit cross-arm.Wire drainage ball is fixed on wire, and forms series gap with lightning arrester drainage ball.When circuit is subject to Lightning Over-voltage, when induction overvoltage not yet reaches insulator arc-over, the discharging gap between wire drainage ball and lightning arrester drainage ball starts electric discharge, and lead lightning current lightning arrester body.Lightning current discharges through lightning arrester body, and power frequency continued flow is then blocked by lightning arrester body, reaches the object of " taking shelter from the thunder ".
Although the lightning protection line overvoltage protection device of said structure can play a protective role to a certain extent, but still has the following disadvantages:
One, when there being big current by current limiting element, current limiting element is damaged because bearing, and as changed or safeguarding not in time, can form huge potential safety hazard;
Two, the discharging gap between wire drainage ball and current limiting element drainage ball can be subject to wind and put and the impact of seasonal variations, occurs the situation of gap discharge instability, affects the protective value of protector.
