Zusammenfassung:	The invention provides a steel rail potential limiting device and a control method. According to the device, one end of a direct current contactor, one end of an anti-parallel thyristor module and oneend of a voltage detection module are connected with an earth screen; the other end of the direct-current contactor is connected with the other end of the anti-parallel thyristor module and then is connected with a steel rail andthe other end ofthe voltage detection module through a current detection module; and a controller is respectively connected with the direct current contactor and the anti-parallel thyristor module. The method comprises the following steps: when a steel rail voltage value respectively reaches a first-section voltage protection setting value, a second-section voltage protection setting value and a third-section voltage protection setting value, respectively controlling the direct current contactor to be switched on in a time delay manner, controlling the direct current contactor to be switc
