Drop out fuse
Is a branch line of 10 kV distribution lines and the distribution transformer is the most commonly used a short-circuit protection switch. It has economic, convenient operation, to adapt to the outdoor environment with the characteristics of strong, is widely used in 10kV distribution lines and the distribution transformer primary side as protection and equipment, operation with. It is installed in the 10kV distribution line branch line, reduce the power outage, because it has a obvious disconnection point, has the function of isolating switch, create a safe working environment to the maintenance section of the line and equipment, increase the sense of the safety of maintenance personnel. Installed on the distribution transformer, can be used as the main protection of distribution transformers, so, in the 10kV distribution lines and distribution transformers have been popularized.
Its working principle is: fuse tube at both ends of the moving contact on fasten the fuse (melt), the moving contact push "duckbill" bulge, phosphorus, copper plate, etc. made of static contact on the top of a moving contact, therefore the fuse tube firmly clamped on the "duckbill". When the short circuit current through the fuse is blown out, arcing, fuse tube lining vulcanized fibre tube under the effect of arc produced large amounts of gas due to the upper end of the fuse pipe is blocked, gas toward the lower end of the spray, blow out the arc. Due to fuse, fuse tube moving contact fuse fastening force lost, the fuse tube static contact spring piece of self gravity, and under, fuse tube falling rapidly, the circuit disconnected, removal of the fault section of the line or equipment failure.
