Problems solved by technology

Its topology is as Figure 17 As shown, the number of components is large and the electrical connection is complicated
[0005] The five semiconductor components of the electrical sub-module all require a large press-fit force to meet their electrical performance. Traditional components are press-packed with large components, and it is difficult to connect wires between components in the unit. This has great impact on the assembly and Maintenance is very difficult

Abstract

The invention provides a direct-current energy consumption device valve module. The direct-current energy consumption device valve module comprises a rectangular frame and a series sub-module arrangedon one side of the rectangular frame. Each sub-module comprises electrical modules which are connected in series. The direct-current energy consumption device valve module is in electrical connection, and the structure is easy to assemble and maintain.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to a valve module of a DC energy consumption device. Background technique [0002] The direct current transmission line can efficiently and conveniently transmit a large amount of electric energy from the energy base to the load center. For the direct current transmission project in operation, the electric energy consumed by the receiving end is balanced with the electric energy sent by the sending end , the voltage and operating frequency of the power grid at the sending end remain constant. When the power system at the receiving end is disturbed or fails and cannot absorb the electric energy sent by the sending end, the voltage and frequency of the sending end power grid will be disturbed, and this disturbance can be reduced by quickly adjusting the output of the generator; if the power supply at the sending end is For thermal or hydroelectric generators, the output of ...
