Abstract
The invention relates to a lightening protection product fault indicator comprising a signal acquisition system, a measurement control unit, an initiation unit, and a mark belt action mechanism, which are sequentially connected. The signal acquisition system, the measurement control unit, the initiation unit and the mark belt action mechanism are combined to form an integrated structure body. The measurement control unit includes a current measurement circuit, a comparator circuit, a trigger circuit, and a protection circuit, which are sequentially connected. A color mark belt is arranged in the mark belt action mechanism. The fault indicator is reliable in guarantee, lays a foundation for wide application of disconnection-preventing (lightening protection) insulators, reduces the work time and difficulty of fault point searching substantially, wins precious time for timely troubleshooting of a power system, and reduces resource waste effectively.
Description
Technical field
The present invention relates to a kind of accident indicator, be specifically related to a kind of power system breaking line preventive (lightning protection) insulator breakdown indicator.
Background technology
Flourish along with electric utility, overhead transmission line insulating has become developing direction, and suspended insulated guide wire is widely used, and it not only solves the environmental protection problems such as tree line, and Electrical Safety accident is greatly decreased.But lightning-caused breaking happens occasionally, it has also become the main restricting factor of overhead transmission line insulating development.For this problem, domestic use the most in a large number breaking line preventive (lightning protection) insulator to substitute traditional support insulator, to reach to prevent the purpose of lightning-caused breaking.But, while breaking line preventive (lightning protection) insulator obtains user's affirmative, user also been proposed new requirement.Aerial insulated wire is intact but breaking line preventive (lightning protection) insulator is difficult to look in trouble point 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 invention aims to overcome deficiency of the prior art, a kind of reliable guarantee is provided, extensively application for breaking line preventive (lightning protection) insulator is paved the way, activity duration and the difficulty of trouble-shooting point are greatly decreased, fix a breakdown in time for power 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 above-mentioned technical problem, a kind of lightning-protected product fault detector of the present invention, it includes 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 includes current measurement circuit, comparator circuit, triggering circuit and protection circuit, and they are linked in sequence；It is provided with colored marking band in described mark band actuating mechanism.
Described integral structure body is provided with installing hole.
Described signal acquiring system uses current transformer.
Initiating unit is similar to electric cap, and when the electric current having certain value passes through, gunpowder detonates.Opening mark band door, mark band is blown out.
The present invention, by the power current of measure-controlling unit detection breaking line preventive (lightning protection) insulator, when power frequency electric flow valuve is not up to setting value, does not start initiating unit；After power current reaches setting value, starting initiating unit, mark band is blown out.When breaking line preventive (lightning protection) insulator is by lightning current, although current amplitude is high, but owing to the time is the shortest, about tens of microseconds, initiating unit will not be started.Protection circuit protection indicator is not damaged when leading to super-high-current.
Beneficial effect: the present invention is compared with prior art, its remarkable advantage is: the present invention uses current transformer to obtain power current, measure-controlling unit ensures when power current reaches setting value, and initiating unit starts, and mark band is blown out and indicated breaking line preventive (lightning protection) insulator to damage.This product safety is reliable, and road has been paved in the extensively application for breaking line preventive (lightning protection) insulator, activity duration and difficulty is greatly decreased, fixes a breakdown in time for power system and win the quality time, effectively reduce the wasting of resources.
