Comprehensive Overview
The Drop-out Fuse and Pull Load Drop-out Fuse are at the pinnacle of outdoor high-voltage electrical protection, designed with precision and innovation. These expertly engineered devices are strategically positioned on the high-voltage side of distribution transformers or act as crucial support links within distribution lines. They serve as vital guardians against transformer and line short circuits, managing overload scenarios while offering seamless current management for opening and loading. The design of the drop-out fuse is a masterpiece of innovation, consisting of an insulating bracket and fuse tubes that securely hold static contacts at each end. The moving contacts are elegantly attached to the ends of the fuse tube. The product features an advanced inner arc tube, coupled with a robust outer phenolic paper tube or epoxy glass cloth tube. The Pull Load Drop-out Fuse stands out for its enhanced versatility, showcasing auxiliary contacts and a meticulously crafted arc chute for smooth current load transitions.

During standard operations, the drop-out fuse remains securely fastened in a closed position, with the fuse tube under precise tension. When system faults arise, the fault current swiftly blows the fuse and generates an arc. This dynamic arc ignites the arc tube, decomposing a generous volume of gas to create high pressure within the tube, forging a vertical wind path that skillfully stretches and elongates the arc. As the fuse blows, the moving contact gracefully releases, rotating outwards while the locking mechanism disengages, allowing the fuse tube to drop and achieve a decisive breaking position. For load pulling, an insulating rod is used to deftly draw out the moving contact while maintaining a connection with the static contact. Continuous force application causes auxiliary contacts to separate, generating an arc that stretches within the hood slit. The arc cover contains the gas efficiently, facilitating effective arc extinguishment as the current approaches zero.

Applications and Compliance Standards
This distinguished product is meticulously engineered for deployment in 10 to 35KV distribution lines, encompassing branching lines and the primary side of distribution transformers. It provides steadfast protection against overloads and short circuits while ensuring the effective separation and combination of the rated load current.
Crafted with precision, this product's engineering adheres to the rigorous JB/T8321-1996 Method for AC high-voltage fuse preparation. Its parameters align with the esteemed GB15166.3-1994 standards for high voltage fuses, specifically Expulsion fuses. In scenarios lacking detailed definitions, adjustments are expertly tailored in accordance with the JB/DQ2139-1986 interim technology requirements for 10 to 35KV outdoor high voltage drop fuses.
The Drop-out Fuse Cutout and Load Switching Fuse Cutout are the epitome of high-performance outdoor high-voltage protective devices. These meticulously designed devices are intended to connect with the incoming feeder of distribution transformers or lines, playing an indispensable role in safeguarding against short circuit incidents and overload conditions while efficiently managing on/off load current. The drop-out fuse cutout comprises robust insulating supports and a fuse tube, with static contacts strategically positioned on both sides and moving contacts expertly affixed at the ends of the fuse tube. The fuse tube boasts a sophisticated internal arc-extinguishing tube, complemented by an outer phenolic compound paper tube or epoxy glass tube. The load switching fuse cutout also incorporates high-performance, elastic auxiliary contacts and an arc-extinguishing enclosure for efficient on-off load current switching.

In standard operational scenarios, the fuse link ensures the fuse tube remains tightly closed. Upon encountering faults, the fault current rapidly melts the fuse, generating an electric arc that heats the arc-extinguishing tube, releasing substantial volumes of gas and creating high pressure to elongate the arc within the tube. Once melted, the moving contact loses tension, allowing the mechanism to lock, and the fuse tube to gracefully drop out and transition to an open position. For cutout load switching, operators deftly utilize an insulating operating bar to draw the moving contact. Initially, the main contact maintains engagement with the auxiliary static contact. As the auxiliary contact is further pulled, an electric arc forms between them, extending within the arc-extinguishing enclosure gap. Simultaneously, the arc-extinguishing mechanism expels gas to efficiently extinguish the arc as the current passes through zero.
