High-voltage drop-out fuses normative operation

High-voltage fuses are the simplest and earliest to use a protective electrical appliance. High-voltage fuses are the simplest and earliest protective electrical appliances used to protect electrical equipment in electrical circuits from overload and short circuit currents. High-voltage fuses cannot be used to properly cut off and turn on current hazards. Must be used in conjunction with other electrical equipment (isolation switches, contactors, circuits, and other electrical appliances (disconnectors, contactors, load switches, etc.). Switches, etc.). Widely used in 1000V and below devices; in devices with voltages up to and below; Widely used in and below devices in high voltages of 3 to 35KV, mainly used as low power power lines, high voltage devices, High-voltage devices are mainly used as protection devices for low-power power lines, electrical transformers, power capacitors, electrical transformers, power capacitors, and voltage transformers.
High-voltage fuses are circuit protection switches that are often used in line branching and distribution transformers because of their high protection performance and their economical convenience when used, which has been well received by many users. In addition, when it is used, it has the advantage of strong adaptability of the environment, that is, no matter what kind of environment it is, it can be used at any time, but it is after all electrical equipment, with a lot of technology, so It must also pay attention to its standard operation during installation.
First of all, avoid touching the heat. There are many users nowadays using this type of drop-type fuse, which often causes the phenomenon of hair-thirsty heat. The biggest reason is that during the installation, the melt is not tight, so under high load Will it make it hot.
Second, pay attention to the angle of the melt tube. When installing a fused pipe, it must be noted that it has a downward inclination, which is generally 25 degrees, so that it can use its own weight to reach the maximum when the high-voltage fuse melts. Good fall.
Then the firmness of the high-voltage drop-out fuse. No matter what the installation is, it is necessary to pay attention to the firmness. This kind of drop-out fuse is no exception. It is usually installed on the stretcher. Therefore, the stretcher must be required to be reliable without any vibration. phenomenon.
Finally, the length of the high-voltage drop-type fuse should pay attention to the correct adjustment, must be moderate, under normal circumstances, are also after the closing, can hold more than two-thirds, so you can avoid the melt in the tube When falling on the ground, unexpected accidents do not occur, and you must be careful not to let it die.
