[Overview] Speaking of fuse molds, in fact, it is necessary to pay attention to the fuse is concerned, it itself is based on the use of voltage that can be divided into high-voltage fuses and low-voltage fuses. The mold is that there will be high-voltage fuse mold and low-voltage fuse mold. Next, according to the protection of its object can be divided into protection of transformers and general electrical equipment with fuses.
Furthermore, in more detail, each type of fuse mold corresponds to a fuse product. In this context, it is also the fuse that protects the voltage transformer and protects the fuse of the power capacitor, and then, in itself, protects the fuses on the semiconductor components and protects the motor from fusing And can also protect the fuses on the home appliances.
According to its fuse mold structure can be divided into open, semi-closed, tube and jet fuse mold. In actual use, when it comes to open-type fuses, we actually find that it is relatively simple in structure. For the melt, it is completely exposed to the air and is made of porcelain Column for support, no bearings, suitable for low pressure outdoor use.
Next, in fact, we should pay attention to the semi-enclosed fuse melt is installed on the porcelain frame above, when inserted into both ends of the ceramic socket with metal socket which is suitable for low-pressure indoor use . Then, as it is in the breaking current, for its sound and light will be more easily blocked by the porcelain box.
Finally, there is a tube-type fuse in the fuse mold, the melt of which is contained in the fuse link. Next, the fuses produced for this type of fuse mold are either inserted into the pedestal or used directly on the circuit. For the fuse-link, that is, both ends of the sleeve there will be a metal cap or a fully enclosed sealed tube with a contact knife.
