Description

A kind of electrical equipment fault automatic early-warning system of infrared imaging temperature measuring
Technical field
The present invention relates to electric device maintenance maintenance technique field.
Background technology
At present, China's economy is constantly fast-developing, and also positive strong intelligent grid ranks stride forward power network, i.e., using extra-high voltage as Major network, the development of different brackets electric network coordination, the safe and stable operation of power system is even more raw safely containing the every profession and trade including colliery The basic guarantee of production.Intelligent grid has the feature of " self-healing ", including following two aspect:First, intelligent grid can be automatically fast The isolated fault of fast ground, and the power supply of normal section is ensured in time;Secondly, grid operating conditions can be monitored on-line, it is occurred Failure alert in time, and adopt an effective means and remove a hidden danger, so as to ensure the safe and reliable operation of power network, avoid power network The generation of failure.
Thus, how using high-tech intelligent means, power network is monitored on-line, automatic fault detection, disappeared in time Except equipment dangerous spot, destructive factor is reduced, and carries out systematization, the management of standardization, is put in power system scientific research personnel face Preceding new problem.And transformer station is the important composition unit of power network, therefore study substation equipment detection and fault diagnosis skill Art has substantial worth, can not only reduce the incidence of accident, also contributes to electric power netting safe running and its reliability Improve.
In order to carry out security monitoring to Substation Electric Equipment, visible ray remote viewing system is generally carried out both at home and abroad and has ground Study carefully and plan, and the technology such as coded image data, compression, transmission and information processing is quite ripe.However, visible ray Remote viewing system is only capable of detecting the external phenomenon of equipment, identical with human eye finding, when the phenomenon one that some can visually perceive Situations such as denier occurs such as explode, smolder, now equipment fault just can not have been prevented and avoided.
In the past few years, actively application of the research infrared thermal imaging technique in terms of electrical equipment is started both at home and abroad, In terms of detection and its Fault Identification judgement mainly to equipment.At present, a kind of hand of commercialization is widely used in power system Formula infrared radiation detection apparatus are held, electrical equipment is detected when it is maked an inspection tour dedicated for operation maintenance personnel and is used.However, the infrared radiation detection apparatus are also deposited In many deficiencies:
