Hollow Reactor Electric Field And Electric Problem Analysis

The Air-core reactor has the advantages of simple structure, light weight, good linearity, low loss, low noise, easy maintenance, in recent years, Air-core Reactor in Electrodynamic Force, metallurgy, mine, chemical industry, wind power and electric railway fields of application. In depth analysis of air-core reactor internal insulation electric field intensity distribution, contribute to the Air-core Reactor insulation design. The Air-core Reactor power analysis, contribute to the design of mechanical strength, avoid Air-core Reactors in a suitable change process undergo great Electrodynamic Force to destroy the reactor.The first chapter on Air-core reactor structure characteristics are expounded, Air-core reactor is composed of a plurality of glass fiber epoxy resin dipping glue solidified coaxial winding package seal, electrical all package are connected together in parallel. Air-core reactor is mainly composed of star frame arm, a reactor coil, Stubbs rods, pillar insulator, a mounting base, the magnetic isolation elevated seat components. Because the Air-core reactor only winding, no core (magnetic shielding reactor with the exception), is essentially a hollow inductor winding.According to the actual structure of Air-core Reactor, using the ANSYS software respectively on the hollow filter reactor, air-core shunt reactor developed a two-dimensional electric field analysis model. Using the Finite element method of electric field analysis model was split, and the electric field analysis, draw the corresponding Air-core Reactor sealing internal electric field intensity and the analysis results. Hollow filter reactor in normal operation, the terminal voltage is generally not too high, this paper use the MATLAB software, the switching state of the terminal voltage are analyzed, and the corresponding analysis results. In addition, for surface insulation cracking reactor, using the Finite element method, the maximum Electric field intensity on the insulation structure and its position was analyzed, and the conclusion, insulation cracking is generated tree discharge on the surface of one of the main reasons.Because the Air-core Reactor main magnetic flux and wire chain, reactor the entrapment in each turn of wire under a certain electrodynamic force. The reactor by Electrodynamic Force, Electrodynamic Force in each package produce mechanical stress, and spread to other components of reactor structure. At rated current, Electrodynamic Force is not great, however in the transient process, core reactor will flow through the larger current, cause Electrodynamic Force surge, even make the reactor fault. The Air-core Reactor under normal operation state and short-time current state of the mechanical properties were calculated, using ANS YS software, obtained the air-core reactor in Electrodynamic Force distribution for Air-core Reactors, the design provides a theoretical basis.
