When replacing customized dropout fuse cutout, generally no load operation is allowed, only no-load equipment is allowed, the rated voltage and rated current levels of customized dropout fuse cutout cannot be expanded or reduced, only fuses with the same volume and the same working voltage level should be removed.
The specific precautions for replacing customized dropout fuse cutout are as follows:
1. The specific operation of replacing the customized dropout fuse cutout is carried out by two people (one person monitors, one person operates), but must wear qualified insulating gloves, insulating boots, wear goggles, and use qualified insulating rods with matching voltage levels. Operation is prohibited in heavy rain weather.
2. During the switching operation, pull the middle phase first, then pull the leeward side phase, and then pull the windward side phase according to the regulations.
3. When closing, the operation sequence is reversed, first close the windward side phase, then close the leeward side phase, and then close the middle phase.
4. The replacement of the fuse tube of the customized dropout fuse cutout is a frequent project. If you do not pay attention, it will cause burns on the contacts, lead to poor contact, overheat the contacts, anneal the spring, make the contact contact worse, and form a vicious circle.
Therefore, moderate force should be used when pulling and closing the fusion pipe. After closing, carefully check that the duckbill and tongue can tightly hold more than two-thirds of the length of the tongue. You can use the pull rod to hook the duckbill, press down a few times, and then try to pull it gently to check whether it fits. If the closing is not in place or firm, the static contact pressure on the customized dropout fuse cutout is insufficient, which may easily cause the contact to burn or the fuse tube to fall by itself.
