Description
Technical field
The utility model relates to a kind of accident indicator, is specifically related to a kind of electric system breaking line preventive (lightning protection) insulator breakdown indicator.
Background technology
Flourish along with electric utility, overhead transmission line insulating becomes developing direction, and suspended insulated guide wire is widely used, and it not only solves the environmental protection problems such as tree line, and significantly reduces Electrical Safety accident.But lightning-caused breaking happens occasionally, become the main restricting factor of overhead transmission line insulating development.For this problem, domestic breaking line preventive (lightning protection) insulator that adopts in a large number carrys out alternative traditional support insulator, to reach the object preventing lightning-caused breaking.But while breaking line preventive (lightning protection) insulator obtains user's affirmative, user also been proposed new requirement.Be difficult to look in trouble spot at intact but breaking line preventive (lightning protection) insulator of aerial insulated wire after suffering broken by lightning, waste time and energy, be badly in need of a kind of breaking line preventive (lightning protection) insulator that can provide obvious fault point, to solve an above-mentioned difficult problem.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome deficiency of the prior art, a kind of reliable guarantee is provided, for the widespread use of breaking line preventive (lightning protection) insulator is paved the way, significantly reduce activity duration and the difficulty of trouble-shooting point, fix a breakdown in time for electric system and win the quality time, effectively reduce the lightning-protected product fault detector of the wasting of resources.
Technical scheme: in order to solve the problems of the technologies described above, a kind of lightning-protected product fault detector described in the utility model, it comprises signal acquiring system, measure-controlling unit, initiating unit and mark band actuating mechanism, they are linked in sequence, described signal acquiring system, measure-controlling unit, initiating unit and mark band actuating mechanism composition integral structure body; Described measure-controlling unit comprises current measurement circuit, comparator circuit, trigger circuit and protection circuit, and they are linked in sequence; Colored marking band is provided with in described mark band actuating mechanism.
Described integral structure body is provided with mounting hole.
Described signal acquiring system adopts current transformer.
Initiating unit is similar to electric detonator, when have the electric current of certain value by time, gunpowder detonates.Open mark band door, mark band is blown out.
The utility model detects the power current of breaking line preventive (lightning protection) insulator by measure-controlling unit, when power frequency electric flow valuve does not reach setting value, does not start initiating unit; After power current reaches setting value, start initiating unit, mark band is blown out.When breaking line preventive (lightning protection) insulator is by lightning current, although current amplitude is high, because the time is very short, about tens of microseconds, can not start initiating unit.Protection circuit protection indicator does not damage by during big current.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model adopts current transformer to obtain power current, when measure-controlling unit ensures that power current reaches setting value, initiating unit starts, and mark band is blown out and indicated breaking line preventive (lightning protection) insulator to damage.This product safety is reliable, for road has been paved in the widespread use of breaking line preventive (lightning protection) insulator, significantly reduces activity duration and difficulty, fixes a breakdown in time and win the quality time, effectively reduce the wasting of resources for electric system.
Accompanying drawing explanation
