自动重合闸装置和防跳回路都是合闸回路的重要组成部分,相互间有密切联系,分析了由SEL微机继电器和VD4断路器机构所组成的合闸回路中,自动重合闸装置和防跳回路配合产生误动作的原因。提出了改变SEL继电器整定值的措施,有效提高了装置性能。
Automatic reclosing device and anti-jump circuit are all the important components of closing circuit. They are closely related to each other. The automatic reclosing device and anti-jump device are analyzed in the closing circuit composed of SEL microprocessor relay and VD4 circuit breaker mechanism. Loop with the cause of malfunction. Proposed to change the setting of the SEL relay measures to effectively improve the performance of the device.
