Embodiment 1
[0063] Such as figure 2 As shown, the ground automatic phase separation device used in the partition of this embodiment includes a control unit 1, a detection unit connected to the control unit 1, two thyristor valve group units 2, and the two thyristor valve group units 2 are located in the neutral zone and the partition. Between the power supply arms of the substation on both sides of the substation, that is, between the neutral zone and the power supply arm on one side, and between the neutral zone and the power supply arm on the other side, a thyristor valve group unit 2 is respectively arranged, and each thyristor valve group unit 2 It includes two thyristor valves connected in anti-parallel connection, each thyristor valve is connected to the control unit 1, when the train is over-phased, the detection unit detects the network pressure signal and the current signal of the two thyristor valve group unit 2, and sends them to the control unit 1, The control unit 1 generate...
Embodiment 2
[0083] Such as Figure 5 As shown, from left to right is forward driving, and from right to left is reverse driving. The thyristor valve group unit 2 of this embodiment specifically includes a thyristor valve connected between the power supply arm of the substation on the left side of the divisional substation and the neutral zone. K1, thyristor valve K3, and thyristor valve K2, thyristor valve K4, thyristor valve K1, thyristor valve K3, thyristor valve K2, and thyristor valve K4 connected between the neutral zone and the power supply arm of the substation on the right side of the district substation are respectively connected with the control The unit 1 is connected, and the control unit 1 generates control signals and sends them to the thyristor valve K1, the thyristor valve K3, the thyristor valve K2, and the thyristor valve K4 to control on-off. By controlling the on-off of thyristor valve K1, thyristor valve K3, thyristor valve K2, and thyristor valve K4 independently thr...
