Transformer state monitoring and diagnosis system

Abstract

The invention provides a transformer state monitoring and diagnosis system. The transformer state monitoring and diagnosis system comprises a MDD host. The transformer state monitoring and diagnosis system is characterized in that the MDD host is connected with a transformer oil chromatogram on-line monitoring subsystem, a transformer partial discharge on-line monitoring subsystem, a transformer oil temperature on-line monitoring subsystem, a transformer winding deformation on-line monitoring subsystem, an iron core grounding current on-line monitoring subsystem and a transformer casing on-line monitoring subsystem. According to the MDD host, an integrated design ideas is adopted; with the transformer adopted as an objective, a hierarchical distributed network structure is adopted; remote, on-line, network centralized monitoring and fault diagnosis on the transformer can be achieved; and defects that the online monitoring systems of different equipment in one substation work independently in an isolated manner can be eliminated, and comprehensive fault diagnosis on the transformer can be realized.

Description

technical field [0001] The invention relates to the field of power supply, in particular to a transformer state monitoring and diagnosis system. Background technique [0002] Since the 1950s, my country's power plants have been carrying out regular blackout tests and maintenance in accordance with the preventive test regulations for power equipment, which is the so-called planned maintenance system. With the continuous increase of power system capacity, continuous improvement of voltage level, and the increasing requirements of power supply departments for power supply reliability, the number of unattended substations is increasing, and it is imperative to implement status monitoring for power system equipment. Row. In this situation, on-line monitoring systems for different high-voltage equipment have emerged as the times require. There are many types of on-line monitoring products for transformers, such as chromatography on-line, bushing insulation on-line, and partial di...
