Problems solved by technology

[0004] The power supply network is complicated, and there are a large number of circuit breakers, and some reclosing functions of circuit breakers on different lines need to be enabled, and some need to be disabled.
At present, dispatchers mainly use manual observation and recording on the spot to monitor and manage the switch-in and withdrawal status of the reclosing switch. First, the efficiency is low, and second, errors and omissions are prone to occur, and the overall effect is poor.

Abstract

The invention relates to the technical field of electric power monitoring, and particularly discloses a reclosing switch on-off state monitoring method which is suitable for power supply lines with breakers. An on-off condition of are closing function of each breaker is determined by anon-off state of the corresponding reclosing switch. The method comprises the following steps: imaging each powersupply line with the breaker to obtain a graphical interface; performing on-off signal acquisition on the on-off state of the reclosing switch corresponding to each power supply line; and differentially displaying a graphic identifier of the breaker in the graphic interface according to the on-off state of the reclosing switch. By using the reclosing switch on-off state monitoring method, automatic monitoring of the on-off states of reclosing switches can be realized, scheduling efficiency is improved and an error and leakage rate is reduced.

Description

technical field [0001] The invention relates to the technical field of electric power monitoring, in particular to a method for monitoring the throwing and withdrawing state of a reclosing switch. Background technique [0002] When the overhead line fault is cleared, closing the circuit breaker in a short time is called reclosing; since most overhead line faults are instantaneous or temporary, reclosing is one of the self-recovery power supply methods often used in operation. [0003] Generally, the reclosing function of the circuit breaker is performed by a reclosing control loop. A reclosing switch is provided in the reclosing control loop. When the reclosing switch is switched on, the reclosing control loop is turned on, and the reclosing function of the circuit breaker is activated. When the reclosing switch exits, the reclosing control circuit is open and the reclosing function of the circuit breaker is disabled. Therefore, the reclosing status of the reclosing switch d...
