PROBLEM TO BE SOLVED: To provide a new electric power transmission equipment capable of avoiding a deterioration in the reliability of power supply side opening and closing elements Ssp, Ssn and charging side opening and closing elements Sbp, Sbn belonging to electric power transmission equipment in the electric power transmission equipment provided with a relaying capacitor 26.SOLUTION: A control device 44 performs opening and closing operations of the power supply opening and closing elements Ssp, Ssn and the charging side opening and closing elements Sbp, Sbn while avoiding both the power supply side opening and closing elements Ssp, Ssn to be a pair and the charging side opening and closing elements Sbp, Sbn to be a pair from being subjected to a closing operation. In such a case, the power supply side opening and closing elements Ssp, Ssn are subjected to opening and closing operations such that switching timing from one to the other between the opening operation and the closing operation is different between the power supply side opening and closing elements Ssp, Ssn to be a pair with each other. In addition, the charging side opening and closing elements Sbp, Sbn are subjected to opening and closing operations such that switching timing from one to the other between the opening operation and the closing operation is different between the charging side opening and closing elements Sbp, Sbn to be a pair with each other. |
