2) replacement of the melt; 1) Before installing a new melt, melt blown to find out the reasons fuses, fuse undetermined reason, do not try to replace them melt delivery: 2, replace them melt asked to do Fuse wholesale, to check whether the melt ratings match the device to be protected; 3) replacement of the melt, check the fuse burns inside of the tube and, if severe burns fuse, should also replace the fuse tube. Porcelain fused pipe damage, do not allow other materials pipe instead. When the filler is melt fuse replacement, pay attention to fill the filler. Fuses can be divided according to the use voltage and low-voltage fuses high-voltage fuses. Fuse (Figure 8) according to the protected object can be divided into protection for transformers and general electrical equipment fuse to protect the voltage transformer fuses, fuse protection of power capacitors, semiconductor element protection fuses to protect the motor fuse and protection fuses and other household appliances. According to the structure can be divided into open, semi-enclosed, tube and jet fuses. Fast Fuse | Fuse Lanzhou | Xi'an by the Xi'an high Huayi power plant.
