Abstract

The invention provides an insulated I-shaped beam of a modularization multi-level voltage source transverter module unit. The insulated beam is used for the modularization multi-level voltage source transverter module unit. The cross section of the insulated beam is in an I shape. The I-shaped beam comprises U-shaped beams which are bilaterally symmetrical. The I-shaped insulated beam is high in rigidity, light in quality and convenient to install and use, and has an excellent mechanical performance and an excellent electrical performance.

Description

technical field [0001] The invention relates to an insulating beam of power electronics, in particular to an insulating I-shaped beam of a modular multilevel voltage source converter module unit. Background technique [0002] In power electronic equipment, converters with IGBT as the core are widely used in low-voltage systems. However, the voltage level of IGBT can only reach several thousand volts, while the voltage level of the power grid may be tens of kilovolts or more. In engineering applications, multi-level technology can be used to obtain high-voltage, large-capacity converters. That is to say, the basic independent modules (referred to as sub-modules) manufactured by low-voltage power devices are expanded into larger module units in a certain way. Through the coordinated control of the control system, higher voltage levels and higher power are realized. commutation function. Modular multi-level voltage source converter is a new topology of VSC. It can not only ef...
