摘　　要：所谓跳跃是指由于合闸回路手合或遥合接点粘连等原因,造成合闸输出端一直带有合闸电压的现象。当开关因故障跳开后,会立刻合上;而保护动作开关会再次跳开,因为一直加有合闸电压,开关又会再次合上。上述情况被通俗地称为“开关跳跃”。一旦发生开关跳跃,开关会被损坏,所以防跳功能是操作回路中一个必不可少的部分。The so-called jump refers to the phenomenon that the closing circuit hand-closed or remote joining joint bonding and other reasons,resulting in the gate output has been with the closing voltage.When the switch jumps off due to a fault,it will close immediately,and the protective action switch will jump off again,because the closing voltage is always applied,and the switch will close again.The above situation is popularly known as"switch jump".Once the switch jumps,the switch will be damaged,so the anti-jump function is an essential part of the operating circuit.
