Description
Technical field
What the present invention proposed is the accessory of power domain, specifically a kind of power line insulators M shape electromagnetic signal emitting pin.
Background technology
Existing power line insulators locks mutually with pin usually, and due to by wind impact, pin easily comes off, and pin comes off descendant for can not perception, therefore easily occurs that insulator is separated from each other, power transmission line is dropped, cause the generation of power-off or security incident.Existing used pin is straight shape, easily comes off.
Summary of the invention
Whether exist in order to pin can be monitored, the invention provides a kind of power line insulators M shape electromagnetic signal emitting pin.This pin adopts M shape, pin is provided with electromagnetic signal emitter, producing induced current by power mains induced electric organ is that electromagnetic signal emitter is powered, electromagnetic signal emitter is generated electromagnetic waves signal, receive by the hand-held telemeter in ground and show, determine whether the sub-pin of every point insulating exists, solve the technical problem of pin state aware.
The scheme that invention technical solution problem adopts is:
Cross-arm by upper insulator and lower insulation subgroup to being interconnected and hanging power transmission line.
In upper insulator mesopore, pin is housed, is provided with joint pin on lower insulator top, in joint pin, is provided with connecting hole, connection hole wall is laterally provided with pin hole, on pin, is also provided with the pin hole corresponding with connecting hole wall simultaneously, and is interspersed with pin.
Pin structure is M shape, and pin is provided with electromagnetic signal emitter.
Electromagnetic induction electric organ is hung with by insulating hanger between power transmission line and foot insulator, at electromagnetic induction electric organ built with induction coil, induction coil one end is connected with earth connection, the other end as power supply output line, power supply output line respectively with insulation subgroup between the pin circuit that interts be connected.
Hand-held telemeter is provided with the Signal reception display corresponding with often organizing insulator pin.
Good effect, the electromagnetic wave signal that the present invention can be sent by ground hand-held telemeter reception pin, thus determine whether each pin exists, therefore, it is possible to monitor the location status of pin in time, come off to avoid pin and cause the generation of accident.Owing to adopting M shape pin, so be not easy to come off.The suitable application of installation as the monitoring of power line insulators pin.
