IEC/ANSI/AS Applicable standard 11kv bushing insulator for fuses
One of the reasons why the fuses on the distribution transformers in the real 10kV line system cannot operate correctly is that the electricians have poor quality and a weak sense of responsibility, and do not carry out maintenance and repair of drop type fuses all year round; The second reason is that the product quality of drop type fuses is poor and cannot be flexibly pulled and closed. Two reasons have reduced the functionality of the drop type fuse. In reality, there are often cases of missing melt tubes, missing melt, or using copper wire, aluminum wire, or even iron wire to hook instead of melt. The tripping rate of the line and the fault rate of the distribution transformer remain high.
Drop-out fuse cutout and load switching fuse cutout are of outdoor used high voltage protective device,Tobe connected with incomin-g feeder of distribution transformer or distribution lines,it mainly protect transformer or lines from short circuit and overload,and on/off loading,current,Drop-out fuse cutout is composed of insulate insulator supports and fuse tube,static contacts is fixed on two sides of insulator support and moving contact is installed on two ends of fuse tube,Fuse tube is composed of inside arcexting tube.Outer phenolic compound paper tube or epoxy glasstube,Load switching fuse cutout provides enfored elastic auxiliry contacts and arc-extinguishing exclosure switching on-off loading current.
