Problems solved by technology
These measures and data are also obtained after several failures. Even so, there are still many problems in the actual heat treatment results, such as excessive partial discharge, excessive skeleton deformation, enameled wire adhesion, etc., basically because the partial discharge exceeds the standard and can only repeat heat treatment. Lead to serious consequences such as skeleton deformation and enameled wire adhesion, resulting in serious waste of manpower, material resources and electricity

The invention discloses a high-voltage test transformer insulation heat treatment system and a heat treatment method thereof. At present, there are many testing and evaluating means for transformer insulation and ageing at home and abroad, and no very good post insulation heat treatment means exits. The system comprises a transformer heat treatment tank, a vacuum degree sensor, a capacitance transmitter, a temperature transmitter, a vacuum pump, a heating device and a control device connected with the vacuum degree sensor, the capacitance transmitter, the temperature transmitter and the heating device; capacitance information collected by the capacitance transmitter comprises capacitance between winding layers of a transformer and between winding and a grounding transformer heat treatmenttank in the heat treatment process, and the control device controls the heating device and the vacuum pump to work according to the collected capacitance information so as to quantitatively control the heat treatment process. According to the technical scheme, qualitative effect analysis and quantitative calculation analysis of insulation treatment can be achieved conveniently, the controllable insulation treatment process is achieved, and the uncertainty of transformer insulation treatment for a high-voltage test is eradicated.
Description
technical field [0001] The invention relates to the field of transformers, in particular to a high-voltage test transformer insulation heat treatment system and a heat treatment method thereof. Background technique [0002] Electric energy is one of the commonly used energy sources for social and economic development today, so it is very important to ensure the normal operation of the power system. As an important part of the power system, the insulation aging of the transformer not only increases the operating cost of the power supply enterprise, but also poses potential safety hazards to the safe operation of the power grid. The insulation aging of the transformer in operation may cause electric leakage, which can lead to personal injury and death accidents caused by electric shock to people and livestock, or damage to electrical equipment caused by lightning hitting the transformer due to weakened insulation, so good insulating materials and insulating parts are the guara...
