Product Description
The detachable arrester is the refitted zinc oxide arrester of the distribution type, and is cleverly installed on the drop-type structure of the drop-out fuse, so that the arrester can be conveniently carried out with the help of insulating brakes and rods under the condition of uninterrupted power supply. Detection, repair and replacement not only ensure the smooth flow of the line, but also greatly reduce the work intensity and time of power maintenance personnel, especially suitable for places where power failure is not suitable, such as post and telecommunications, airport stations, hospitals, bustling business districts, etc. Other properties of the product are the same as the distribution type arrester. The second-generation drop arrester adds a disconnector. When an abnormality occurs in the arrester, the power frequency short-circuit current is used to make the disconnector move, so that the grounding end of the disconnector is automatically disconnected, and the arrester element falls and exits operation to prevent further expansion of the accident. It is easy for maintenance personnel to find and repair and replace in time.
Our company adopts the most advanced RWI2 type drop mechanism in the world at present, with reliable contact, flexible opening and closing, and advanced accessories of stainless steel cover with composite pillars, which are anti-fouling, fast action, wide current range, and can withstand the specified current. Advantages of shock and motion loads. The product performance meets the national standard GB11032-2000 (eqvIEC60099-4:1991) "AC non-gap metal oxide arrester", JB/T8952-2005 "composite jacket non-gap metal oxide arrester for AC system", GB311.1-1997 " Insulation coordination of high-voltage power transmission and transformation equipment.
