The invention discloses a maintenance safety protection method for a charging rail of an energy storage type tramcar, which is suitable for maintenance of the charging rail in a field section and comprises the following steps: after a vehicle enters the field section and an energy storage unit is completely discharged, moving a roof charging rail to a recovery position; when the car roof charging rail moves away to the recovery position, an additional negative pole branch is formed, so that the car roof charging rail is communicated with the steel rail (negative pole). The invention further discloses an overhaul safety protection device for the charging rail of the tramcar. According to the method and the device provided by the invention, the car roof charging rail is communicated with the steel rail (negative pole) by forming an additional negative pole branch when the car roof charging rail is moved to the recovery position, so that the charging rail can be directly connected with the steel rail during maintenance; the situation of wrong charging caused by the fact that the rail-ground transition impedance or the internal resistance of the energy storage element cannot be recognized is avoided, and potential safety hazards are completely eradicated.
本申请公开了一种用于储能式有轨电车充电轨的检修安全防护方法,适用于场段内的充电轨检修,其包括在车辆进入场段内并在储能单位完全放电之后,将车顶充电轨移动至回收位置处,在车顶充电轨移开至回收位置处时形成额外的负极支路,使车顶充电轨与钢轨(负极)连通。本发明还公开了一种用于有轨电车充电轨的检修安全防护装置。本发明的方法和装置通过在车顶充电轨移开至回收位置处时形成额外的负极支路,使车顶充电轨与钢轨(负极)连通,从而可以使得在检修期间充电轨与钢轨直连,不会出现因为无法识别轨地过渡阻抗还是储能元件内阻而导致的误充电情况,杜绝安全隐患。
