The utility model provides a holding storehouse and high -speed EMUs for high voltage component relates to the high -speed railway transportation and equips the design and manufacturing technology. Being used for high voltage component's holding storehouse, setting up on the top of automobile body, the holding storehouse is including dull and stereotyped, and the flat board is used for being connected with the top of automobile body, be provided with the mounting hole that is used for installing high voltage component on the flat board, and dull and stereotyped bottom is provided with the mounting base of the formula of sinking that is used for holding high voltage component, the mounting base still communicates with the guiding device to water in the discharge holding storehouse. High -speed EMUs include above -mentioned holding storehouse. Be used for the mounting base of holding high voltage component's the formula of sinking through the setting, can have the not mounting surface of co -altitude for the rail surface for each high voltage component provides to can effectively utilize the cubical space at automobile body top, reduce each high voltage component's interval, dwindle and arrange that the required automobile body top of high voltage component is regional, and then make the not smooth -going region of automobile body obviously reduce, improve automobile body streamline performance, reduce resistance to motion.
