Hand-held acousto-optic detector

Technical Field

The utility model relates to the technical field of acousto-optic detectors, in particular to a handheld acousto-optic detector.

Background

At present, the unattended transformer substation mainly tends to develop to a five-tele direction (telemetry, remote signaling, remote control, remote regulation and remote vision), a video monitoring system is utilized, the remote vision function is gradually realized in the transformer substation, but the monitoring of the internal sound of the operation equipment is not emphasized, the developed complete equipment is very few, and an intelligent audio recognition system aiming at the operation state of the power equipment is less.

The power equipment can emit various sounds in the operation process, and the operation state of the equipment, even the fault type, can be judged according to the sound change intensity. The existing inspection mode is often carried out by manual spot inspection, in order to judge the fault type of the transformer, one end of an insulating rod commonly used by a transformer substation operator is placed on an oil tank of the transformer, and the other end of the insulating rod is placed on an ear to carefully listen to sound. The method is simple to operate, but cannot realize remote continuous online detection, and does not accord with the development trend of an unattended transformer substation; meanwhile, the detection personnel are required to have abundant practical experience, and an unstable factor is brought to the accuracy of judgment.

In order to comprehensively master the real-time running condition of a transformer substation, discover fault equipment in time and make scientific decisions and processes, a novel portable imaging equipment audio monitoring method is necessary to be researched, the running state of the equipment is analyzed and recorded through monitoring the sound signals of the equipment in running, and the method is matched with the existing monitoring system of the transformer substation, so that the actual running condition of the equipment is mastered from multiple aspects, the management of the transformer substation system is optimized, and the method has important practical significance for improving the running and maintenance efficiency and reliability of the equipment, collecting the equipment data and prolonging the service life of the equipment.
