Overview
This series of product is applied to power system with indoor AC50HZ-60HZ, rated voltage being 3. 6kv -405kv, and it could be cooperation-uscd with other protection electric device(such as vacuum con-nector,load switch etc) to be overload or short protection compon-ents of highvoltage motor, electrical voltage transformer voltage mutual conduc torand other elcctrical equipment
This product is suitable for indoor AC 50Hz, rated voltage 3.6KV, 7.2KV, 12KV, 24KV, 40.5KV systems. It can be used with other switches, electrical appliances (such as load switches, vacuum contactors), power transformers and other electrical equipment. It is reliable and can reliably cut off any fault current between the minimum breaking current and the rated breaking current. It also has the high breaking capacity of the limited current fuse, and has better small current for non current limiting fuse. Protection characteristics, good full range disconnection protection characteristics can be obtained.
Product Structure
The high-voltage fuse has the advantages of good current limiting characteristics, high breaking capacity, fast and accurate action, reliable operation, etc. It also features small installation volume and reliable contact; The impactor is connected in parallel with the molten liquid made of pure silver, and the chemically treated high-purity quartz sand is sealed in the melting tube: the melting tube is made of high-temperature and high-strength alumina ceramics. When the production line fails, the melt melts. At the moment of arc in the melt, the high resistance metal wire of the impactor parallel to the melt is immediately ignited, and the high pressure generated by igniting the gunpowder will rapidly spray the impactor and push the interlocking electric contact. Automatically switch circuit or send fuse signal.
