Detailed Product Description: | PRWG2-35KV outdoor fall-fuse - Xing melt electrical The PRWG2-35KV outdoor drop fuse - Shanghai (Yueqing) Hing melting Electric Co., Ltd. specialized in manufacturing high voltage fuse, high voltage wall bushings, high-voltage load switch, high voltage insulator, high voltage surge arrester and so on. 24-hour nationwide service hotline 577 -57,777,272. Official website: http://www.shxrdq.com/ \ PRWG2-35KV outdoor drop fuse [product information] First, an overview The drop-out fuse and pull the load drop-out fuse is outdoor high-voltage protection of electrical. It installed in the high pressure side of the distribution transformer or distribution lines, trunk road, used as a transformer and line short circuit, overload, and points to co-load current. Drop fuse the two parts of the insulating bracket and fuse tube, static ports installed in the inner arc tube and the outer layer of insulation bracket both ends of the moving contacts installed in both ends of the fuse tube, fuse tube Phenolic paper tube or epoxy glass cloth tube. Pull the load drop fuse enhanced flexibility auxiliary contact and interrupter cover for the points, co-load current. Drop-out fuse in normal operation, the fuse tube to form a closed position with the fuse tension. When a system failure, fault current fuse quickly blows, and the formation of the arc, the arc tube arc burning, decomposition of large amounts of gas, the formation of high pressure inside the embassy, ??and the formation of vertical blowing along the pipeline, arc rapidly elongated And go out. Fuse blows, the lower part of the moving contacts lose tension of two down, locking mechanism, release the fuse tube, fuse tube drop, the formation of a breaking position. Opened the moving contact when the need to pull the load, with insulating rod, and this time take the initiative to, static and dynamic contact still contacts continue to use the insulated rod pulling contacts, auxiliary contacts separation between the auxiliary contact arcing, arc off cover a slot in the elongated, while the interrupter cover the gas, the zero crossing of the current arc will extinguish. Second, use Outdoor high-voltage fuse applies to the 50Hz power system of the 35kv and under voltage and frequency for the transmission line, power transformer overload and short circuit protection, division and rated load current with mechanical life of ≥ 2000. Third, the conditions of use Applies to the ceiling for ambient temperature 40 ° C, the lower limit of -30 ℃ within. Altitude does not exceed 1000m, the wind speed is not greater than 35m / s, 3 fuse does not apply to the following places 3.1 have fuel or explosion hazard areas. 3.2 The place of the severe vibration or shock. 3.3 There are different electrochemical gas and serious air of filthy, smoke areas. Fourth, the structure Introduction The fuses are composed of two parts of the base and arc suppression device to the bottom of the interrupter tube fitted with a possible rotation of the spring bracket, always fuse a state of tension, to ensure that the interrupter tube in the closing position of self-locking, line and transformer overload or short circuit in the fuse fuse fuse rapidly from out of the interrupter tube, the interrupter pipe is designed to progressively exhaust to solve breaking size of the current contradictions in the same fuse.
