Nondestructive test electric power monitoring device, system and method

Abstract

The invention provides a nondestructive test electric power monitoring device, system and method. The nondestructive test electric power monitoring device includes a multi-turn spiral induction coil, an AD sampling module, and a processor, the multi-turn spiral induction coil winds on the power line of an electric device, the first end of the multi-turn spiral induction coil is connected with the AD sampling module, the AD sampling module is further connected with the processor, the multi-turn spiral induction coil inducts the power frequency electromagnetic field of the power line, the processor controls the AD sampling module to acquire the first voltage value corresponding to the power frequency electromagnetic field and obtain the first voltage value, and determines whether the power line has faults based on the relation between the first voltage value and the preset voltage value. The nondestructive test electric power monitoring device, system and method ensure the power line security level and the integrity of the power line while realize the effective monitoring of the working state of the power line, thereby improving the user's satisfaction.

Description

technical field [0001] The invention relates to power monitoring technology, in particular to a non-destructive detection type power monitoring device, system and method. Background technique [0002] At present, IoT sensors mostly monitor environmental parameters such as temperature, humidity, and air quality. It is of great significance to maintain the normal operation of the equipment. The normal power supply to environmental maintenance equipment is the primary factor to ensure the normal operation of environmental equipment, so it is necessary to monitor the power of environmental maintenance equipment. Wherein, the power monitoring refers to detecting whether the power line of the environmental maintenance equipment is working normally. [0003] The power monitoring in the prior art mainly adopts on-line monitoring and transformer monitoring. On-line monitoring is to monitor the measuring equipment connected in series on the power line, and the transformer monitorin...

AI Technical Summary

Problems solved by technology

Since the online monitoring equipment is connected in series on the circuit, if the measurement equipment fails, it will lead to the failure of the overall line of the environmental maintenance equipment, which reduces the safety level of the overall line and cannot be used in high-safety occasions.

Transformer monitoring Since the mutual induction coil can only be effectively inserted into the live wire on the power line, it is necessary to cut the power line in which the live wire and the neutral wire are packaged together, and put the transformer on the live wire separately. generally unacceptable
