specific Embodiment approach
[0060] The specific implementation of the converter valve of the present invention: 1) first install the slide rail 2 on the bottom plate 23 of the chassis 3, then install the dovetail groove 4 on one of the radiators 7 of the sub-module 1, and install the connecting piece 6 2) Install the backplane 8 into the chassis 3, slide the SCE board 9, the low-voltage power supply board 10, and the IGBT driver 11 into the chassis 3 through the guide rail 18, and plug in and out through the backplane The terminal 17 is electrically connected to the backplane 8; 3) The fuse board 12 and the high-voltage power supply board 13 are fixed to the top of the chassis 3 . 4) Connect each adjacent side plate of the chassis 3, and the side plate and the cover plate 16 through the buckle 221 and the buckle hole 141; The whole body is slidably installed above the radiator 7, and when the connecting piece 6 is slid to limit fit with the chassis, the chassis 3 is fixedly connected with the connecting ...
specific Embodiment 2
[0064] Specific embodiment 2 of the converter valve of the present invention, the converter valve includes at least two converter valve sub-module assemblies, and the converter valve sub-module assembly includes a sub-module and a converter valve sub-module control for controlling the sub-modules The circuit unit, the control circuit unit of the converter valve sub-module includes a chassis, which is integrated with a backplane and at least two control circuit boards that are conductively connected to the backplane for controlling the submodules, and the backplane is connected to the submodule The terminals of the sub-modules are conductively connected to realize the control of the sub-modules by each control circuit board. At least two control circuit boards are integrated in the same case. When performing fixed installation of the control circuit unit of the converter valve sub-module, it is only necessary to install the control circuit board integrated in the case in the cas...
specific Embodiment 5
[0067] The specific embodiment 5 of the converter valve of the present invention, as a further optimization of the specific embodiment 4 of the converter valve of the present invention, in order to prevent the rainwater entering the chassis from flowing to the sub-module terminals along the wires, the bottom plate in this embodiment An annular boss protrudes upward from the wire passing hole. The ring-shaped boss can block rainwater on the outer periphery of the wire hole, preventing rainwater from flowing along the wire to the terminal of the sub-module, causing a safety accident. In other embodiments, no annular boss may be provided at the wire passing hole.
[0068] The specific embodiment 6 of the converter valve of the present invention, as a further optimization of the specific embodiment 4 of the converter valve of the present invention, in order to prevent the rainwater from flowing along the chassis to the sub-modules, in this embodiment, there is a protrusion under t...
