The invention discloses a simulation method based on a three-dimensional full-size physical model of a high-voltage shunt reactor, which adopts multi-physics field coupling simulation software to establish the three-dimensional full-size physical model considering an internal structural member, and simulates and analyzes the influence of fastener looseness on the vibration and propagation characteristics of the high-voltage shunt reactor. Research results show that the reduction of the pretightening force of the iron core cake and the pull rod causes the intensification of the vibration of the reactor iron core and the shell, and the vibration influence on the top end of the iron core column and the upper parts of the front and side surfaces of the shell is more obvious; compared with a pull rod, vibration increase caused by looseness of the iron core is more obvious. A simulation result can provide a theoretical basis for defect detection and fault diagnosis of the high-voltage shunt reactor based on acoustic vibration signals.
Description
technical field [0001] The invention relates to the field of vibration characteristic analysis of a high-voltage shunt reactor, in particular to a simulation method based on a three-dimensional full-scale physical model of the high-voltage shunt reactor. Background technique [0002] The high-voltage shunt reactor is mainly used to compensate the reactive power of the power system and suppress the overvoltage of the line. It is an important equipment to ensure the safe and stable operation of the power system. In order to avoid magnetic saturation, the high-voltage shunt reactor core adopts a segmented core structure, which has large magnetic leakage and more serious mechanical vibration compared with transformers. The severe vibration of high-voltage shunt reactors during long-term operation can easily lead to fatigue and loosening of coils, iron cores (clamps), bolt fasteners and other components. The decrease in preload force will further aggravate the occurrence of vibra...
