During operation of power networks, fuse carries the protective effect for cut-offfing line short fault electric current.Short circuit current Bigger, arc energy is bigger, burns stronger, the time of arc extinction is longer.The expansion of heat, gas that arc burning generates There is great harm to fuse with gas ionization decomposition product.In order to increase safety in utilization, the selection of fuse insulating casing It is most important with preparing.
Insulating sleeve as a kind of high security haveing excellent performance, it is necessary to meet following condition:
(1) when short circuit, electric arc can be knocked out in a very short period of time, lead scattered arc energy rapidly, to reduce molten The occurrence probability of disconnected device bursting accident.
(2) there is higher mechanical strength, the arc energy generated when because cut-offfing is very high, if intensity is not high, easily makes fuse Explosion.
(3) there is good heat resistance.Fuse can be made to generate heat when power on circuitry, insulating inner tube temperature is led to up to 100 DEG C sometimes Temperature can also be higher when crossing moment larger current.
(4) ageing-resistant, especially use outdoors, be chronically at light, electricity, heat, under wet influence, if material is easy to old Change, then the trial period can greatly shorten, and seriously affect the operational reliability of product.
Currently, insulating coating used in domestic high voltage electric appliance is still using ceramics as main material, this material fabrication process is multiple It is miscellaneous, and production process energy consumption is high, causes a large amount of energy waste, especially ceramic coat in use easily because of arc energy It is excessively high and burst, this to the personal safety either to circuit safety or operator for, be all to avoid greatly.
