The invention provides a tramcar roof inverter box. The tramcar roof inverter box comprises a box body used for installing inverter elements and an air duct cavity arranged below the box body. The air duct cavity comprises a first drawer body and a second drawer body. The air duct cavity is a cooling air duct independent of the box body, and the air duct cavity can expand the space of the bottom of the box body through pulling, so that the bottom of the box body is convenient to overhaul and clean. When water is accumulated on the roof, the box body can meet the requirements of ventilation and water tightness. After the second drawer body is drawn out relative to the first drawer body, compared with the inverter box in a stable use state, the space of the air duct cavity is further expanded, and maintenance and cleaning work is greatly facilitated.
本申请提供的有轨电车车顶逆变器箱,包括:用于安装逆变器元件的箱体,以及设置于箱体下方的风道腔体;风道腔体包括第一抽屉体和第二抽屉体。风道腔体是独立于箱体的冷却风道,并且风道腔体可通过抽拉扩大箱体底部的空间,便于检修和清洁箱体底部。车顶积水时,箱体可以兼顾通风和水密性要求。在第二抽屉体相对第一抽屉体抽出后,相比于逆变器箱处于稳定使用时的状态,风道腔体空间得到进一步扩大,极大地便利了检修和清洁工作。
