Abstract

The invention belongs to the field of electrical safety monitoring, and discloses an electrical safety monitoring and warning method and device. The method includes the following steps: acquiring first monitoring parameters of an electrical circuit; comparing the first monitoring parameters with set thresholds; and giving a warning for potential electrical safety hazards according to the comparison results. The first monitoring parameters include: residual active power and load power, or / and resistive residual current, or / and insulation conductance, or / and intermittent leakage harmonic currentand intermittent leakage harmonic power, wherein the residual active power is used as a monitoring parameter for determining whether a potential electrical safety hazard occurs on an electrical line,the load power is used as a monitoring parameter for determining whether a potential electrical safety hazard occurs on electrical equipment, the resistive residual current is used as a monitoring parameter for residual current type potential electrical safety hazards, the insulation conductance is used as a monitoring parameter for hidden danger of electrical insulation, and the intermittent leakage harmonic current and the intermittent leakage harmonic power are used as fault arc monitoring parameters. Comprehensive and efficient monitoring of electrical safety can be realized.

Description

technical field [0001] The invention relates to the field of electrical safety monitoring, in particular to an electrical safety monitoring and early warning method and device. Background technique [0002] With the large-scale popularization of electric power applications, the number of accidents such as electrical safety and electrical fires has also increased significantly. Especially at the present stage in our country, the incidence rate of electrical fires has remained high for a long time. Electrical fires account for about 30% of the total fires in my country, and the proportion of electrical fires in serious and extraordinarily large fires is as high as 60%. Accidents are basically caused by electrical fires. This is because electrical fires have the characteristics of strong concealment, rapid burning, and mostly occur at night, and the victims do not have enough time to escape. [0003] Electrical insulation aging is the main cause of electrical failures, safety a...
