Embodiment Construction

[0037] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] The invention relates to a crimping type IEGT flexible DC transmission power module, such as figure 1 As shown, the box 100 is provided with a vacuum contactor 300 , a power module 500 , a controller 600 , an IEGT power unit 200 , and an energy storage capacitor 400 in sequence from front to back.

[0039] Wherein, the vacuum contactor 300 provides a bypass disconnection function for the circuit of the entire power module. Due to its large size, it is arranged at the lowermost position in the front of the box body 100 to facilitate maintenance and operation. At the same time, the vacuum contactor 300 The conductive bus bar of the whole power module is also directly used as the external connection bus bar of the whole power module, which av...

The crimping IEGT flexible DC transmission power module includes a casing and an IEGT power unit and an energy storage unit which are arranged in the casing in a front-rear layout, the IEGT power unit and the energy storage unit are connected by a DC laminated busbar, the input end of a power supply module is connected with the DC laminated busbar, the output end of the power supply module is connected with a controller, and the controller is connected with an IEGT driver and a vacuum contactor. The power module has the characteristics of large power density, simple and smooth power flow, convenient detachment and maintenance, scientific and reasonable water cooling pipeline setting, good cooling performance, high electrical wiring operability and anti-interference capability, and stable overall performance, and has the leakproof function.

Description

technical field [0001] The invention belongs to the technical field of direct current transmission, and specifically relates to a press-connection type IEGT flexible direct current transmission power module, which is mainly used in the fields of new energy access to large power grids, island power transmission, urban ring networks, and interconnection of asynchronous power systems. Background technique [0002] Flexible DC transmission technology, also known as VSC-HVDC technology, is a new DC transmission technology based on Voltage Source Converter (VSC) and Insulated Gate Bipolar Transistor (IGBT), and is an upgrade of conventional DC transmission technology. Compared with AC power transmission and conventional DC power transmission, it can flexibly adjust the voltage of the AC system connected to it while transmitting energy. The advantages of DC transmission technology are extended to the distribution network, which greatly broadens the application range of HVDC and has...
