High Voltage Falling Fuse 12kv

We are providing a wide range of high voltage falling fuse 12KV to our most valued client's. SSOC(NCF) outdoor AC high voltage falling fuse series are the devices for over current protection.The fuse installed on the distribution transformer or pole of power line serves as device for overload protection and switch on/off the load current.The fuse is composed of a main insulating and conducting structure and an arcing tube.The stationary contacts are fixed at both ends of the fuse tube composed of an arcing tube inside and an phenolic paper tube or epoxy glass tube outside.Equipped with a arcing chamber and elastic auxiliary contacts to interrupt load current and cappacitor current the SSOC(NCF)3 fuse is able to switch on/off the load current.
Principle
In operation the fuse tube with tightened fuse is at position "close".The fuse is melted quickly with fault current when system suffers from failure.Heated by arc the tube gives off gas which blows longitudinally along the tube and increases the pressure inside.As a result,the arc will be distinguished radically.After the fuse is below out the lower moving contact will turn downward due to the loss of tension to lock the mechanism and release the fuse tube.The fuse tube will fall down to realize a clear breaking.When it is necessary to pull the load,use the insulating rod to draw away the moving.
