The present invention relates to a circuit breaker operation monitoring method for quickly and completely closing a circuit breaker when a circuit breaker requiring synchronization verification is selected.
従来、この種遮断器の操作手順を示すものとし

５を動作させて該遮断器を投入する。 Conventionally, the operating procedure for this type of circuit breaker is shown in FIG. 1. In the illustrated circuit breaker operation monitoring method, in STEP 1,
First, the circuit breaker selection circuit 1 selects a circuit breaker. Then, it is determined whether synchronization verification is performed by the selected circuit breaker. When it is determined that the circuit breaker requires synchronization verification based on the above-described determination of the presence or absence of synchronization verification, the process moves to STEP 2, the synchronization verification operation switch 2 is turned on, and the synchronization verification circuit 3 performs synchronization verification. Further, after the synchronization is confirmed by the synchronization detection circuit 4, the process moves to STEP 3 and the circuit breaker closing operation circuit 5 is operated to close the circuit breaker.

回路１はリセツトされる。 On the other hand, if the above synchronization judgment in STEP 1 determines that the selected circuit breaker does not require synchronization verification by closing, immediately
The process moves to STEP 3, and the circuit breaker closing operation circuit 5 is operated to close the circuit breaker. When those circuit breakers are turned on, the circuit breaker selection circuit 1 is reset.

る方法として、第２図に示すものがあつた。 However, the conventional circuit breaker operation and monitoring described above relies on the operator's judgment as to whether or not a synchronization test has been performed when closing the circuit breaker, and an incorrect judgment can result in an accident. There is a big possibility. For this reason, a method shown in FIG. 2 has been proposed as a method for preventing accidents caused by the above-mentioned erroneous determination.

戻ることになり、不必要な操作をしなければなら
ず、その操作が煩わしくまたロス操作が多くな
る。 That is, the operating procedure shown in the second diagram performs the synchronization verification.
Before proceeding to STEP 2, even if a breaker that requires synchronization verification is selected in STEP 1, the closing operation of that breaker is restricted unless synchronization verification switch 2 is operated. After 2 is inserted, the lock is released and a synchronization test is performed. However, in this case, if the operator mistakenly determines that synchronization is not required, the operator will move to STEP 3 and then learn that the circuit breaker closing operation circuit 5 is inoperable, and then return to STEP 2, resulting in the failure. Necessary operations must be performed, which are cumbersome and result in many loss operations.

る。 The present invention has been made in order to eliminate the above-mentioned drawbacks of the conventional circuit breaker, and includes a synchronization determination circuit that determines whether synchronization has been detected for the circuit breaker to be selected, and a display that displays the determination result. The present invention provides a method for monitoring the operation of a circuit breaker, which allows synchronization verification of the circuit breaker and its closing operation to be quickly and safely performed without malfunctioning by means of the display.

を行う。 Hereinafter, one embodiment of the present invention will be described based on FIG. 3. According to the illustrated operation monitoring method, in STEP 1, the circuit breaker selected by the circuit breaker selection circuit 1 is tested for synchronization by the synchronization determination circuit 6. The presence or absence is determined. When a circuit breaker requiring synchronization verification is selected, the closing operation of that circuit breaker is locked, and the display 7 outputs a display signal of the synchronization verification operation to be performed. Then, the display 7
When the operator turns on the synchronization verification switch 2, the circuit breaker closing operation lock is released, and the synchronization verification circuit 3 is configured, and the synchronization detection circuit 4 allows the synchronization detection circuit 4 to transfer to STEP 2. When the synchronization status of is detected, STEP3
will be moved to Then, in STEP 3, the closing operation circuit 5 is operated to issue a command to close the circuit breaker. Furthermore, the display 7 and the circuit breaker selection circuit 1 are reset by the closing operation of the circuit breaker, and the process is completed.
On the other hand, after the synchronization determination circuit 6 described above determines that the selected circuit breaker does not require synchronization,
Immediately after moving from STEP1 to STEP3, the closing operation circuit 5 is operated to close the circuit breaker.
