Product details
Our company has developed a new V-shaped structure windproof drop type fuse based on wind farms, which effectively avoids accidents. According to the analysis of the wind farm, our company's product can solve the problem. The improvement mainly involves increasing the thickness of the upper and lower contact steel support plates to 12 millimeters, changing the contact points, all using copper alloy precision castings, increasing the current flow rate, effectively avoiding increased contact resistance and operational changes, changing the structure of the upper contact point, adding auxiliary contacts, installing locking state cards and parts, and improving the original tongue plate to 2 millimeters phosphor bronze material to better increase elasticity. Adding auxiliary contacts to the contacts on the high-pressure melting tube can effectively prevent and control wind speeds up to 50 meters by changing the structure of the closing contacts to avoid situations where they are not easily dropped or fail to fall during operation. High temperature resistant resin and glass fiber winding process have also been added to the high-pressure melting tube to avoid spontaneous combustion of the melting tube due to temperature changes. The high-voltage fuse uses quaternary alloy material with a melting temperature of 219 degrees, effectively reducing the arc time and temperature of fault current. Our company's products are equipped with fixed structural components at the drainage line, which are less likely to cause resonance between the wires and contact parts during operation, thus avoiding the generation of electric sparks during operation.
