Abstract

【課題】高圧区分開閉器(PAS)のGR制御器の動作確認試験を、制御出力線を切り離すことなく、いつでも安全・簡単に行うことができるようにしたGR試験補助装置を提供する。【解決手段】GR制御器トリップ信号出力1はGR試験補助装置の信号入力2に接続、通常は「PAS/試験」切り替えスイッチ3「PAS」側を経て出力端子8より区分開閉器(PAS)のトリップコイル9へ接続する。GR制御器の動作試験を行う場合は「PAS/試験」切り替えスイッチ3を「試験」側にして制御器トリップ出力をPASから切り離し、ダミー抵抗R1:4へ接続する。これによりGR試験器はPASに連動することなく制御器単体の動作試験を行うことが可能となる。月次点検等においてはGR制御器のテストボタンを押して制御器の表示を確認するとともに、補助装置の動作表示LED6の点灯によりトリップ出力の電圧を確認することができる。【選択図】図1A GR test auxiliary device is provided that can perform an operation confirmation test of a GR controller of a high voltage section switch (PAS) safely and easily at any time without disconnecting a control output line. A GR controller trip signal output 1 is connected to a signal input 2 of a GR test auxiliary device, and usually through a "PAS / test" changeover switch 3 "PAS" side from an output terminal 8 to a section switch (PAS). Connect to trip coil 9. When performing an operation test of the GR controller, the “PAS / test” changeover switch 3 is set to the “test” side to disconnect the controller trip output from the PAS and connect it to the dummy resistor R1: 4. As a result, the GR tester can perform an operation test of the controller alone without interlocking with the PAS. In monthly inspection, etc., the test button of the GR controller can be pressed to check the controller display, and the trip output voltage can be checked by turning on the operation display LED 6 of the auxiliary device.

Description

本考案は、GR制御器の動作試験に関するものである。   The present invention relates to an operation test of a GR controller.

高圧区分開閉器(PAS)のGR制御器において、年次点検等における制御器単体の動作試験は、区分開閉器のトリップ動作をさせないため、制御出力線をはずして行っている。この操作にあたっては、作業条件の悪い状況のなかで、制御線が他と接触しないように充分注意を払い、狭隘な制御端子板で制御線の取り外しおよび取付け作業を行っている。   In the GR controller of the high voltage section switch (PAS), the operation test of the controller alone in the annual inspection etc. is performed with the control output line disconnected to prevent the section switch from tripping. In this operation, paying attention to prevent the control line from coming into contact with other conditions under poor working conditions, the control line is removed and attached with a narrow control terminal board.

月次点検等における制御器の動作確認は、制御電源や異常の表示確認のみに限られ、制御動作の確認は行われていない。その理由は過去において、制御線処理の作業途中で制御器を故障させるなどの事例が発生しているからである。   The operation check of the controller in the monthly check or the like is limited only to the control power supply and the display confirmation of abnormality, and the control operation is not checked. This is because there have been cases in the past such as failure of the controller during the control line processing.

しかし、年次点検時に限らず夏期の襲雷時等においては、制御器の動作確認を行う必要があり、安全・簡単に動作点検ができる方法が望まれていた。 However, it is necessary to check the operation of the controller not only at the annual inspection but also at the time of a lightning strike in the summer, etc., and a method capable of checking the operation safely and easily has been desired.

解決しようとする問題点は、GR制御装置の動作確認が安全・簡単にできない点である。   The problem to be solved is that it is not possible to confirm the operation of the GR controller safely and easily.

本考案は、GR制御装置のトリップ信号出力と区分開閉器(PAS)トリップ信号入力間に、簡単な試験補助装置を付加することにより、制御線の取り外し等を行うことなく、GR制御器の動作確認ができることを特徴とする。   The present invention adds a simple test auxiliary device between the trip signal output of the GR controller and the section switch (PAS) trip signal input, so that the operation of the GR controller can be performed without removing the control line. It can be confirmed.

本考案のGR試験補助装置により、GR制御器の動作確認をいつでも安全・簡単に行うことができる。   With the GR test auxiliary device of the present invention, the operation check of the GR controller can be performed safely and easily at any time.

図1はGR試験補助装置を示した説明図である。(実施例1)FIG. 1 is an explanatory view showing a GR test auxiliary device. Example 1

いつでも安全・簡単にGR制御器の動作確認を行うという目的を、簡単な補助装置を付加することで実現した。   The purpose of confirming the operation of the GR controller safely and easily at any time was realized by adding a simple auxiliary device.

図1は、本考案装置の1実施例の回路図であって、1はGR制御器トリップ出力であり、9は区分開閉器(PAS)トリップコイル入力である。   FIG. 1 is a circuit diagram of an embodiment of the device according to the present invention, in which 1 is a GR controller trip output and 9 is a section switch (PAS) trip coil input.

GR制御器トリップ信号出力1はGR試験補助装置の信号入力2に接続、通常は「PAS/試験」切り替えスイッチ3「PAS」側を経て出力端子8より区分開閉器(PAS)のトリップコイル9へ接続される。   The GR controller trip signal output 1 is connected to the signal input 2 of the GR test auxiliary device, usually via the "PAS / test" selector switch 3 "PAS" side and from the output terminal 8 to the trip coil 9 of the segment switch (PAS) Connected.

GR制御器の動作試験を行う場合は「PAS/試験」切り替えスイッチ3を「試験」側にして制御器トリップ出力をPASから切り離し、ダミー抵抗R1:4へ接続する。これによりGR試験器はPASに連動することなく制御器単体の動作試験を行うことが可能となる。月次点検等においてはGR制御器のテストボタンを押して制御器の表示を確認するとともに、補助装置の動作表示LED6の点灯によりトリップ出力の電圧を確認することができる。   When performing an operation test of the GR controller, the “PAS / test” selector switch 3 is set to the “test” side to disconnect the controller trip output from the PAS and connect it to the dummy resistor R1: 4. As a result, the GR tester can perform an operation test of the controller alone without being linked to the PAS. In monthly inspection, etc., the test button of the GR controller can be pressed to check the controller display, and the trip output voltage can be checked by turning on the operation display LED 6 of the auxiliary device.

GR試験装置の動作時間測定についてはダミー抵抗R1:4の両端の電圧を、出力端子7よりGR試験装置トリップ信号電圧入力に接続することで動作時間測定が可能となる。 Regarding the operation time measurement of the GR test apparatus, the operation time can be measured by connecting the voltage across the dummy resistor R1: 4 from the output terminal 7 to the GR test apparatus trip signal voltage input.

また年次点検等においては、区分開閉器(PAS)の内部絶縁環境の確認のため、制御線Va,VCを制御器から切り離してトリップコイルの絶縁抵抗を測定していたが、本装置を使用することにより、制御線を切り離すことなく切り替えスイッチ3を「試験」の状態で、端子8の絶縁抵抗を測定することによってその目的は達せられる。 In addition, in the annual inspection, etc., the insulation resistance of the trip coil was measured by disconnecting the control lines Va and VC from the controller to confirm the internal insulation environment of the section switch (PAS). Thus, the object can be achieved by measuring the insulation resistance of the terminal 8 with the change-over switch 3 in the “test” state without disconnecting the control line.
