1, drop-out fuse and pull the load drop fuse is outdoor high-voltage electrical protection, it assembled in the distribution transformer high side or distribution lines branch trunk road, for transmission lines, power transformers overload and short circuit protection and division and rated load current use. 2. Introduction to drop fuse structure consists of two parts insulated bracket and fuse tubes, static contact insulation installed at both ends of the stent, the moving contact is installed at both ends of the fuse tube fuse from the inner tube Consumers arc tube and the outer glass epoxy components. Pull the load drop fuse head and increase the flexibility of the auxiliary interrupter cover to open, close the load current. Drop-out fuse in normal operation, the fuse tube by means of a fuse to form a closed position after tensioning. When the system fails, the fault current to fuse rapidly fuse and form an arc, arc extinguishing the arc tube by burning, decomposition of large amounts of gas, so that the formation of high pressure in the pipe, and the formation of vertical blowing along the pipeline, the arc is rapidly stretched extinguished. 3, the implementation of standards of product performance in line with national standards GB15166.3-94. 4, using the conditions 1, ambient temperature: -40 ℃ ~ 40 ℃; 2, altitude not exceeding 1200m; 3, the wind speed is not greater than 35m / s; 4, earthquake intensity does not exceed 8 degrees; product 5, does not apply to fuses The following places; a, there is a fire or explosion hazard sites; b, there are severe vibration or shock sites; c, there are different electrochemical gas effect and severe air contamination, salt spray areas. 6. Ordering Information 1, product type, name, rated voltage, rated current, rated breaking current; 2, environmental requirements (pollution prevention, Plateau); 3, special requirements can be negotiated with the company. 7, fuse operation and maintenance management (1) fuses and fuse with rated current and the load current value is to match the appropriate tie must be adjusted if improperly. (2) fuses each operation must be carefully, not careless, especially in the closing operation, must be dynamic and static contact good contact (3) To avoid drop-out fuse disconnect repeatedly rated breaking capacity for melting steel pipe wall paper tube fuse, rated breaking capacity succession should not exceed three times. Must be used within (4) standard melt melting tube regular manufacturers, prohibit the use of copper instead of aluminum wire fuse, but not allowed to use copper wire, aluminum wire and live wire lashing use the contacts. (5) for a new installation or replacement of the fuse, to strict inspection procedures, regulations must meet quality requirements. After fusing (6) should be replaced with a new fuse with the specifications of the melt, melt blown not link up again after melting into the tube to continue to use. (7) should be regularly inspected for fuses, night patrol at least once a month, to see whether the spark and bad phenomenon, not power, will be accompanied by a hissing sound, as soon as possible to arrange for treatment.
