Comprehensive Overview
The Drop-out Fuse and Pull Load Drop-out Fuse signify the pinnacle of outdoor high-voltage electrical protection. Each meticulously engineered device is strategically installed on the high-voltage side of distribution transformers or as integral support links within distribution lines. They serve as essential guardians, protecting against transformer and line short circuits and overload scenarios while enabling seamless current management for opening and loading operations. With an innovative design, the drop-out fuse integrates an insulating bracket and fuse tubes, securely clamping static contacts at each end, while the moving contacts are elegantly attached to the ends of the fuse tube. The fuse tube features a cutting-edge inner arc tube, combined with a robust outer phenolic paper tube or epoxy glass cloth tube. The Pull Load Drop-out Fuse stands out with its enhanced versatility, featuring auxiliary contacts and a meticulously crafted arc chute for smooth current load transitions.

During regular operations, the drop-out fuse is fastened securely in a closed position, with the fuse tube held under precise tension. Upon fault detection, the fault current acts swiftly, blowing the fuse and generating an arc. This vigorous arc ignites the arc tube, decomposing a significant volume of gas and creating high pressure within the tube to forge a vertical wind path that skillfully stretches and elongates the arc. As the fuse blows, the moving contact releases, elegantly rotating outwards while the locking mechanism disengages, allowing the fuse tube to drop and achieve a definitive breaking position. When load pulling is required, an insulating rod is employed to draw out the moving contact while maintaining connection with the static contact. With continuous force application, the auxiliary contacts separate, generating an arc that stretches within the hood slit. The arc cover adeptly contains the gas, facilitating efficient arc extinguishment as the current approaches zero.

Applications and Compliance Standards
This esteemed product is meticulously designed for deployment in 10 to 35KV distribution lines, encompassing branching lines and the primary side of distribution transformers. It provides unwavering protection against overloads and short circuits while ensuring effective separation and combination of the rated load current, delivering unmatched reliability in high-voltage environments.
The precision-crafted design of this product meets the rigorous JB/T8321-1996 Method for AC high-voltage fuse preparation. Its specifications align with the prestigious GB15166.3-1994 standards for high voltage fuses Expulsion fuses. In the absence of detailed definitions, adjustments are 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 represent the zenith of high-performance outdoor high-voltage protective devices. Meticulously designed to connect with the incoming feeder of distribution transformers or lines, they play a vital role in protecting transformers and lines from short circuit incidents and overload conditions while adeptly managing the on/off load current. The drop-out fuse cutout comprises robust insulating supports and a fuse tube, with static contacts strategically fixed on both sides and moving contacts expertly affixed at the ends of the fuse tube. The fuse tube features 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 typical operational situations, the fuse link ensures the fuse tube remains tightly closed. Upon encountering faults, the fault current swiftly 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, transitioning to an open position. For cutout load switching, operators deftly utilize an insulating operating bar to draw the moving contact. Initially, the main contact remains engaged with the auxiliary static contact. As the auxiliary contact is pulled further, 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.
