要因となるので、遮断器に抵抗投入方式を採用するなど
によって、開閉サージの低減方策が講じられる。In particular, the magnitude of the switching surge largely depends on the system condition, and in the case of the 275 kV system or less, the lightning surge is generally the determining factor. However, in the 500 kV system, the air flashover characteristic of switching surge is saturated, which is the main factor in the insulation design. Therefore, a measure to reduce switching surge can be taken by adopting a resistance closing method for the circuit breaker.

たは数百Ω程度の抵抗が設置されている。For example, a circuit breaker with a resistor is designed to insert a resistor once in series with a line to suppress the switching overvoltage when the circuit breaker is turned on or off, and an optimal resistance value exists depending on the system configuration. All 500 kV circuit breakers in Japan have a resistance of 1 kΩ or several hundred Ω.

ないという問題があった。The idea of the circuit breaker with a resistor is such that the structure of the device is complicated, and the power is always turned off when a part of the device is replaced or added, so that the circuit breaker must be operated at all times. There was a problem that devices that cannot be replaced cannot be replaced or added.

To prevent this, a connector is provided with an ordinary electrode and an electrode that is connected earlier than the ordinary electrode in terms of time, so that when connecting the connector, a weak current is applied to the electrode that is connected earlier than the ordinary electrode. Since the capacitors used in the circuit are charged, inrush current can be prevented and noise and malfunction of the circuit can be prevented. Alternatively, it can be performed without stopping the device at the time of expansion for the function expansion.
