Abstract

The invention provides a current transformer state monitoring system and method. The current transformer state monitoring system is characterized in that the system comprises a controller unit, a current transformer monitoring unit, a temperature monitoring unit, a humidity monitoring unit, a wireless communication unit, a monitoring processing unit, a status display unit, a voice alarm unit and a power supply unit. The system and method can monitor the running state of a current transformer online, can collect the operation parameters of the current transformer in real time, can realize wireless in-station transmission of monitoring data of the current transformer, can carry out identification and diagnosis on operation troubles of the current transformer, realize state monitoring and fault early warning of the current transformer, carry out voice alarm on fault information of the current transformer and send the fault alarm information to working personnel wirelessly for timely processing, thereby ensuring normal operation of the current transformer.

Description

technical field [0001] The invention belongs to the field of power system state monitoring, and relates to a state monitoring system and method of electric equipment, in particular to a state monitoring system and method of a current transformer. Background technique [0002] The transformer is one of the indispensable main equipment for the normal operation, monitoring, measurement, protection and control of the power grid. Its existence enables the application of high voltage and high current information. The quality of the transformer's operating status directly affects the accuracy of power system measurement and measurement, the reliability of relay protection and automatic devices, and has a great impact on the safe operation of the power system. [0003] At present, current transformers are widely used in power systems, but the problem of condition monitoring of current transformers has not been well studied and solved. The current transformer itself has performance...
