HRW11-10/100A, HRW11-10/200A, RW11-10/100A, RW11-10/200A outdoor high-voltage drop-out fuse 

 First, use 
 HRW11-10/100A, HRW11-10/200A Outdoor AC high voltage drop fuse for 10 kV 50Hz and 60Hz power system for transmission and distribution lines and power transformer short-circuit protection and overload protection. 

 Second, the scope 
 1. Product of the environmental conditions: 
 (1) the ambient temperature is not higher than +40 ℃, not less than -40 ℃; 
 (2) Altitude less than 1000m; 
 (3) wind speed is not greater than 35m / s; 
 (4) not more than eight seismic intensity. 
 2. Product does not apply to the following sites: 
 (1) Combustion or dangerous place; 
 (2) places severe vibration or shock; 
 (3) conducting, the role of chemical gases and heavy pollution areas. 

 Third, the structure and operation principle 
 Products from porcelain insulators, the upper and lower static contact and fuse tubes of three parts, the upper and lower static contact installed in the insulator at both ends, mounting plate fixed to the insulator the middle. Fuse tube material, it not only has good breaking capacity, and ensure a high mechanical strength. Products with mounting plate fixed to the mounting bracket. Fuse in series in power system operation, in normal operation, with the buttons installed in the fuse tube fuse contacts are used on the film's release with pressure relief cap pressed to fuse the end of line through the melting wire tube pulled out, twisted back pressure plate will pop up near vents, and under the contact link, the pop-up fuse panel under the effect of torque has been in a tight connection status, and tighten the joint activities. In the fuse at the closing position, due to the static contact down and outward thrust of shrapnel, so that more reliable contact with the fuse. When the power system failure, fault current will be quickly blown fuse in the fuse tube arc, the arc tube fuse under the action of a large amount of gas, when the pressure of the gas over to the set value, the release button pressed is the first open , reducing the pressure inside the fuse tube, the current zero crossing to produce a strong effect of the arc off free. When the gas pressure does not exceed the value to be set, the release tablet does not move, the strong current zero crossing to produce free gas emitted from the bottom vents, pop-up panel fuse tails pulled quickly, so that the arc goes out. Fuse blows, the release of active joints, fuse tube in the static contact, under pressure from shrapnel, coupled with its role in weight rapidly drops, the circuit is cut off to form a clear breaking gap.
