*fuse supporter (fuse base) In many application cases, fuse links are installe on fuse supporters/application Cases.They are not to be used as switches for connectionand disconnecton of the load. *factors to be considered for selection of fuse links 1.Normal working current 2.Working voltage 3.Ambient temperture 4.Overload current and cutout time 5.Possible malfunction current 6.Impluse current surge current starting current and transient value of the line 7.Size and dimensions connection methods indicators etc According to the order
1. Use (H) RW 12-27 drop fuse and pull-load drop fuse are outdoor high-voltage protective appliances, which are assembled on the high-voltage side of distribution transformer or branch lines of distribution line, and are used for overload and short-circuit protection of transmission lines and power transformers and for sharing rated load current. 2. Brief introduction of structure The drop fuse consists of two parts: insulating bracket and fuse pipe. The static contacts are installed at both ends of the insulating bracket, and the movable contacts are installed at both ends of the fuse pipe. The fuse pipe consists of an inner arc extinguishing tube and an outer epoxy glass tube. Pull-load drop fuse adds elastic auxiliary head and arc extinguishing cover to divide and close load current. When a drop fuse is in normal operation, the fuse pipe is tensioned by means of the fuse. Then a closed position is formed. When the system fails, the fault current causes the fuse to fuse rapidly and form an arc. The arc extinguishing tube is heated by the arc and decomposes a large number of gases, which forms a high pressure in the tube and blows longitudinally along the pipeline. The arc is rapidly elongated and extinguished. After the fuse is fused, the lower moving contact loses tension and turns down. The locking mechanism releases the fuse tube, and the fuse tube falls down, forming an obvious breaking position. When the load needs to be pulled, the contact is pulled by the insulating rod. At this time, the active and static contacts are still in contact. The contacts are pulled by the insulating rod, and the auxiliary contacts are separated. Arc is generated between the auxiliary contacts. The arc is elongated in the slot of the arc extinguishing hood. At the same time, the arc is extinguished when the current passes zero. 3. Implementation criteria The product performance conforms to GB15166.3-94 national standard and IEC282-2 international standard. 4. Conditions of Use 1. Environmental temperature: - 40 ~40 C; 2. No more than 1200 m above sea level; 3. The wind speed is not more than 35m/s. 4. Earthquake intensity does not exceed 8 degrees. 5. Fuses are not suitable for the following places: A. Places where there is a danger of combustion or explosion; B. Places with violent vibration or shock; C. Areas with heteroelectrochemical gases, severe air pollution and salt fog. 5. Instructions for Order 1. Product type, name, rated voltage, rated current and rated switching-on current; 2. Environmental requirements (anti-pollution, plateau type); 3. Special requirements can be consulted with our company. Manufacturer of intelligent switch cabinet--low-voltage, high voltage power distribution switch cabinet, also have many other electric equipment electric power accessories, intelligent transmission and distribution automation system
Drop out fuses and load-drop fuses are outdoor high voltage protection appliances. It is installed on the high voltage side of the distribution transformer or on the branch line of the distribution line. used as a short circuit of the transformer and the line, overload protection and split load current. The drop fuse is composed of two parts: An insulating bracket and a fuse tube. The static contact is installed at two ends of the insulating bracket, the movable contact is installed at both ends of the fuse tube, and the fuse tube is composed of an inner arc extinguishing tube and an outer layer. It consists of a phenolic paper tube or an epoxy glass tube. The load drop fuse enhances the elastic auxiliary contact and the arc extinguishing cover to divide and combine the load current. Product use environment: 1. The ambient temperature is not higher than +40 C, not lower than-40 C 2.The altitude does not exceed 3000m 3.The maximum wind speed does not exceed 35m/s 4.The earthquake intensity does not exceed 8 degrees Product Character: 1,High mechanical strength 2,Good pollution resistance performance 3,Acid and alkalis resistance 4,Good brittle resistance 5,Easy to install
