NETWORK FOR ONLINE MONITORING OF POWER TRANSFORMER AT INTELLIGENT SUBSTATION

摘要

A network for online monitoring of a power transformer at an intelligent substation, the network comprehensively taking into consideration all the current online monitoring items for a power transformer, including online monitoring of gas and micro-water dissolved in oil, online monitoring of sleeve pipes, online monitoring of winding optical fiber temperature measurement, online monitoring of local discharge, online monitoring of iron core grounding current, online monitoring of infrared temperature measurement, online monitoring of vibration, online monitoring of transformer load capacity, etc.; and comprehensively studying and specifying the basic configuration, technical parameters, etc. of each monitoring item. For the network for online monitoring of a power transformer at an intelligent substation, the technologies of online monitoring of a power transformer at an intelligent substation are studied in detail, the study covering the current monitoring principles and monitoring technology indicators of all transformer online monitoring units domestically available, and transformer load capacity monitoring units are proposed and applied for the first time, and the functions of online monitoring system software are studied in detail, thus establishing a complete set of normative technical standards of a power transformer online monitoring system for intelligent substations in the whole province.
