Therefore, an important inspection of the disconnecting switch is required. Under the general circumstances, for the safety and dustproof, waterproof and oilproof, each power plant is to put the export isolator of generating set in the sealed cowling to set up transparent organic glass observation window on the dustcoat of plug-in strip top, the staff of being convenient for looks over isolator's running state.
The isolating switch mainly has the following states: the closed state, the split state, the incomplete closed state, the incomplete split state and the open-phase operation. In the on-state and the off-state, the disconnecting switch is normal. Under other states, the isolating switch is in an abnormal state, and the isolating switch operates in the abnormal state, so that the isolating switch can influence equipment of the isolating switch, and the operation of other power generation equipment can be influenced when serious.
The knife type isolating switch can be separated and closed incompletely, the influence on power generation equipment is large under the condition, and serious accidents can be generated in serious cases. The isolating switch belongs to a normal operation state in a fully closed and fully separated state, and has certain problems in other states, and the operation of power generation equipment can be seriously influenced in some states.
In daily work, power plant staff can check and process when relevant alarms appear in a monitoring system besides checking the isolating switch during daily equipment inspection. However, when an alarm related to the isolating switch is sent, the equipment has obvious faults, and normal and stable operation of the generator set can be affected. Therefore, the abnormal state of the isolating switch needs to be timely found in advance, and the abnormal state is rapidly and accurately processed, so that the safe and stable operation of the generator set is ensured.
