Operation principle of the present utility model is:
Surge arrester with external series gaps faulty indication operation principle:
Surge arrester with external series gaps is under normal operating condition; lightning arrester body 1 is in series with special disconnector 2, faulty indication electrode 3 and air gap successively; the ground end of lightning arrester body 1 upper end and protected insulator or equipment links; faulty indication electrode 3 is separated by by air gap and system high pressure; lightning arrester comprises that accident indicator is in parallel with protected insulator or equipment by the air gap; various atmosphere and system's internal overvoltage are added on lightning arrester body 1 and the air gap by accident indicator, and lightning arrester is realized various superpotential effective restrictions.Because accident indicator before action, is a short-circuit condition with respect to lightning arrester body 1, thus accident indicator to lightning arrester normal overvoltage protection work do not have influence.Because disconnector 2 normal running (operation) conditions can not move, faulty indication electrode 3 is also by special disconnector 2 and lightning arrester body 1 positive connection, as the state indication of lightning arrester operate as normal, referring to accompanying drawing 1 and accompanying drawing 2.
When surge arrester with external series gaps suffers thunder and lightning or system operation overcurrent, special disconnector 2 keeps non-action state, make faulty indication electrode 3 still by disconnector 2 and lightning arrester body 1 positive connection, it is unaffected to guarantee to continue to keep the normal operation operating state indication of lightning arrester.
When lightning arrester suffers thunder and lightning or system operation overcurrent, because special disconnector 2 can misoperation, so deterioration or flashover occurs after lightning arrester body 1 long-time running, behind the short trouble, the 50Hz power frequency continued flow of system is by the startup loop of special disconnector 2, make special disconnector 2 instantaneous operations be separated into two halves, because faulty indication electrode 3 and special disconnector 2 mechanical attachment, the action of special disconnector 2 breaks away from makes faulty indication electrode 3 lose fixing with lightning arrester body, separate with lightning arrester body and drop into ground, realized the malfunction indication of lightning arrester body.
Because the equal plurality of faulty indication electrode 3 length and widths doubly even tens of times of direction boards or indication coloured flag plant bulk, is maked an inspection tour personnel apart from the ground of hundreds of meters of lightning arresters, can be easy to observe electrodeless faulty indication.
Because faulty indication electrode double as lightning arrester guest performer clearance electrode, state indication normal or fault does not need additional source of energy-passive device, has realized simple structure, high reliability, and target has extensive use promotional value and basis cheaply.
