Urban rail construction, particularly underground railway construction, is also expanding in succession. The power supply mode of the urban rail transit is that electric energy is fed to a train in the form of an overhead contact line or a third rail through direct current traction transformation arranged along the line, and a running rail is used as a return circuit for returning. The third rail is a special light steel rail laid in parallel on one side of the steel rail, the shape of the third rail is similar to that of the steel rail, the shape of the section of the third rail is also in an I shape, but the third rail is much smaller than that of the steel rail, and the third rail is also called a current receiving rail. When the train operates, the collector shoe at the bottom of the train contacts the third rail to transmit power. At present, the third rail power supply voltage in China is 750 volts of direct current and 1500 volts of direct current. The traveling rail allows the live voltage to be dozens to hundreds of volts, but when a train passes through, large current flows on a corresponding section, and the return current can reach hundreds of amperes.

At present, a third rail is supported on a road surface through a plurality of insulators and is paved, and the third rail between the insulator supporting pieces is exposed and suspended outside without insulation treatment, so that accidents are easy to happen, and a solution is needed.
