Description
図は三相二線式配電線断線区間検出用区分開閉器の断線
の有無検出用のオーブンデルタ回路、投入コイル操作リ
レー、人工接地装置の原理並に構造の大要を示すもので
ある。The figure shows an overview of the principle and structure of an oven delta circuit, a closing coil operation relay, and an artificial grounding device for detecting the presence or absence of a break in a sectional switch for detecting a break in a three-phase, two-wire distribution line.
Claims (1)
閉器内の電源側区間末端３端子より、オープンデルタ結
線１７の負荷コイル１８を以て、電源側３線の何れの１
線が断線しても断線個所以降は単相になり、１Ｂコイル
が該重相電流にて投入コイル１６の回路のリレーｂ接点
を開いて開閉器を開くと同時に、２の生き線はリレーａ
接点により、１或は３の生き線は１４なる磁性体円盤の
落下により接地に導き断線区間を検出する三相三線式配
電線断線区間検出用区分開閉器。Connect any one of the three wires on the power supply side using the load coil 18 of the open delta connection 17 from the three terminals at the end of the power supply side section in the sectional switch used to detect the disconnection section in the three-phase three-wire electric line.
Even if the wire is disconnected, it becomes single-phase after the disconnection point, and at the same time, the 1B coil opens the relay B contact of the circuit of the closing coil 16 with the heavy phase current and opens the switch, and at the same time, the 2nd live wire is connected to the relay A.
A three-phase three-wire distribution line disconnection section detection switch that connects live wires 1 and 3 to the ground by falling magnetic disks 14 and detects disconnection sections.
