The On-line Insulates Monitor And Studies Application On The Main Transformer Of The 220kV Transformer Substation

The Shengli oil-field electrified barbed wire netting is generates electricity, changes the electricity, power supply in the integral of self-provided electrified barbed wire netting of biggest business enterprise in whole country. It owns 168 the transformer substation of 35 —220kV, It turns the amount of power supply about 60 hundred million kWh, tallest carry 1,070,000 kW every year. Electrified barbed wire netting of safe circulate to the pass the importance, especially normal circulate of the transformer substation equipments has the important meaning to assurance circulating of the electrified barbed wire netting and produce stability of oil-field. The main transformer of transformer substation is the main equipment of the electric power system, the security and reliability of the electric power system is directly influenced by its reliability, in order to guarantee the safe circulate of the electric power system, The insulation monitoring of the main transformer is necessarily reinforced.The on-line monitor principle and applied researches of dielectric loss of a tube of main transformer, with the dielectric loss for the on-line monitor principle method of the current and voltage leads zero phase shifts , analyzed to produce the reason of the error margin and the source of the system interferences, put forward the in keeping with spot the method of the actual anti-interference. Measuring the data actually explains possibility ofon-line monitor system of dielectric loss of the transformer' s tube. The research of the on-line monitoring of grounding electric current in iron core presents the new method that adopts diverse long-string sensor.The on-line monitor principle and applied researches of six kinds of dissolved gases in the transformer oil is the on-line chromatogram monitoring method based on various gases characteristic of the permeable film and multi-transmit gas sensitive component. Measuring the data actually analyzes the stability and the credibility.The research that develops the on-line monitor of the main transformer expanded the comprehensive automation no body' s station to lay a foundation for the oil-field, provide the dependable basis. Circulate the analytical enunciation: The on-line monitoring of the main transformer is reasonable and credible. It can judge the insulate condition of the main transformer.
