RW11-10 drop-out fuse device, RW11 high drop switch, RW11 drop-melt ..

First, the model: RW11-10 / 100A 200A RW11-10F / 100A 200A HRW11-10 / 100A 200A HRW11-10F / 100A 200A RW11-10 drop-out fuse and pull the load drop fuse is outdoor high-voltage protection of electrical, it assembled In the high voltage side of distribution transformer or distribution lines branch trunk road, as transmission lines, electric power transformer overload and short circuit protection and division and rated load current use. ◆ structure Introduction RW11-10 high drop-out fuse consists of two parts insulating holder 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 tube is made inner and outer arc tube composed of glass epoxy. Pull the load drop fuse head and increase flexibility auxiliary interrupter cover to open, close the load current. RW11-10 high 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 tube by electric arc burning, decomposition of large amounts of gas, so that the formation of a high pressure tube, and to form a vertical blowing along the pipeline, the arc is quickly stretched extinguished. After the fuse is blown, the lower part of the moving contacts lose tension and the next turn, the locking mechanism to release the fuse tube, fuse tube drop, breaking forming a clear position. When you need to pull the load, the moving contact with the insulating rod pull, then take the initiative, to help contact remains stationary contacts, continue contacts with insulating rod pull, auxiliary contacts are separated between auxiliary contacts arcing, the arc is elongated slit in the arc chute, while arc chute produce gas in the current zero, the arc is extinguished. ◆ performance standards RW11-10 high drop-out fuse, product performance in line with national standards and IEC282-2 GB15166.3-94 international standards. Conditions of Use 1, ambient temperature: -40 ℃ ~ 40 ℃; 2, altitude does not exceed 1000m; 3, the wind speed is not greater than 35m / s; 4, earthquake intensity does not exceed 8 degrees; fuses apply to the following places: a, there is a fire or explosion hazard place; b, there is severe vibration or shock place; c, there are different electrochemical gas effect and severe air contamination, salt spray areas. 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
