Fault diagnosis device for electrical equipment using smart socket

Abstract

The invention discloses a fault diagnosis device for electrical equipment using smart socket. According to a specific embodiment of the present invention, based on the measured current of the corresponding load and the measured voltage of the corresponding circuit measured by a converter and a voltage sensor of the smart socket and the zero-phase current measured by the zero-phase converter, the harmful leakage current, overload, parallel arc and series arc precursor of each load are diagnosed in real time and the diagnosis result is transmitted to the user terminal, thereby preventing electrical damage of the corresponding load.

Description

technical field [0001] The present invention relates to a device for diagnosing faults of electrical equipment using smart sockets for each load, and in more detail, to a device based on the measured current of the corresponding load measured by the converter of the smart socket, the measured voltage measured by the voltage sensor, and the zero phase change The zero-phase current measured by the current meter, the real-time diagnosis of electrical faults of each load, including harmful leakage current, overload, parallel arc and series arc precursor, and the diagnosis result is transmitted to the user terminal, so as to prevent the electrical damage of the corresponding load. . Background technique [0002] In general, using electricity is convenient, but if it is not properly managed or used incorrectly, it is very dangerous, and there is a high possibility of serious accidents such as electrical fires and electric shocks. [0003] For this reason, after connecting the con...

Problems solved by technology

[0004] However, since the set current varies with the measurement point of the actual measured current and the type of load, it is difficult to diagnose whether there is an abnormality in various loads with a fixed set current.

[0005] As in the above-mentioned prior art documents, there is no suggestion at all of the following technology, that is, in the socket for supplying power to electronic products, especially through wireless communication (Bluetooth communication or Zigbee communication) to transmit the power consumed by a plurality of electronic products used in the home. Diagnose the abnormal state of the electrical equipment of each load for the current, voltage and zero-phase current that fluctuate according to the type of load in the smart socket such as the amount of current
