1. Operation sequence of power failure:
1) When the drop-open fuses are arranged horizontally and there is wind, the power outage operation should be carried out against the wind direction. First open the leeward side drop-out fuse, then pull out the middle-phase drop-out fuse, and finally pull out the upper-wind side. Drop-out fuse. When the drop-out fuses are arranged horizontally and there is no wind, the middle-phase drop-out fuse should be opened first, and then the left and right side-phase drop-out fuses should be opened.
2) Kada su osigurači raspoređeni u trokut i postoji vjetar, operacija nestanka struje bi prvo trebala otvoriti osigurač sa zavjetrinske strane, zatim izvući gornji osigurač pada na strani vjetra i na kraju izvući osigurač pada srednje faze. Kada su osigurači raspoređeni u trougao i nema vjetra, operacija nestanka struje prvo otvara lijevi i desni fazni ispadni osigurač, a zatim izvlači osigurač srednje faze.
2. Redoslijed operacija prijenosa energije: Bez obzira na to da li su osigurači raspoređeni u trokut ili horizontalno, operacija prijenosa energije treba prvo zatvoriti osigurač pada srednje faze, a zatim zatvoriti osigurače s obje strane.
3. Upotrijebite osigurač za zaustavljanje i slanje grananja i sekvence rada transformatora:
1) Shutdown of distribution transformers. First, open the air circuit breaker or low-voltage fuse on the low-voltage side of the transformer, stop the low-voltage load of the distribution transformer, and then open the drop-out fuse on the high-voltage side of the distribution transformer.
2) The distribution transformer is put into operation. First close the drop-out fuse on the high-voltage side of the distribution transformer, and then close the air circuit breaker or low-voltage fuse on the low-voltage side of the transformer.
3) The drop-out fuse of the branch line is out of service. The operator shall operate according to the outage operation sequence of a single distribution transformer, outage the distribution transformers on the branch line one by one, and finally open the drop fuse that controls the branch line and remove the fuse tube. The power delivery procedure is the opposite.
