=====================================

When changing the setting value of distance protection, there was no withdrawal from the protection outlet pressure plate, and because of improper force, the setting value was set to low setting value, which caused the misoperation of I section of distance protection. Due to the poor performance of the components on the distance protection plug-in, the action value is changed, resulting in misoperation of the phase-to-phase distance exceeding. Because the auxiliary contact of busbar grounding switch is not in good contact and the voltage circuit is out of voltage, the distance protection section I trip when the system is in operation. Because the signal return button is stuck on the distance protection screen, the operator did not find it in time, which caused the signal relay return coil to be heated with electricity for a long time, and the signal relay return coil to be connected with the starting coil, the starting distance protects the main outlet relay CKJ, causing the breaker to trip. Due to the poor quality of the power supply, the coil and contact of the relay in the operating circuit will be burned out, and the protection will trip due to Maloperation. In addition, because of component damage, such as VFC board to the accident capacitor breakdown, resulting in earthing distance protection I section trip. Compared with the series DC motor, the asynchronous motor has several remarkable advantages:

誰愛菊?誰采到了菊?問茫茫塵世，幾人能夠?面向黃土背朝天的山野村夫，名韁利鎖的官宦商賈，菊花與他們無關，也無緣。有了放下，才會騰出手來采菊;有了割舍，才會接納傾情于菊。--謝正龍《采菊東籬下》
