HY5WS-17/50DL 10KV Removable Zinc Oxide Arrester Drop-out arrester
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.
Model Description
Product Structural features and scope of use
1. The arrester unit can be loaded and unloaded at any time with electricity, especially suitable for places where power failure is not suitable.
2. With a disconnector, when the arrester unit fails, it can automatically fall down and exit operation to ensure the normal operation of the line.
3. When the unit falls down, a clear sign is formed, which is easy to find and repair and replace in time.
4. The arrester adopts composite jacket, and the drop mechanism adopts composite pillar, which has good water repellency and strong anti-fouling ability.
a.An ambient temperature of -40 degrees to +40 degrees C
b.Height is not more than 3000m
c.Power frequency of 48 Hz~62Hz
d.The maximum wind speed of no more than 35m/s
e.Seismic intensity of 7 degree and below
Product installation instructions
1. This product should be installed on the line of the system and equipment whose rated voltage is consistent with the rated voltage of the arrester.
2. Before installation and use, please check the tightness between the arrester element and the drop mechanism to ensure good contact and flexible casting.
3. Adjustment method: Rotate the copper contact (with pull ring) on the arrester to make the opening pulling force within 6~10KG, and keep the pull ring side of the copper contact facing outward, and then tighten the lower nut to make the pull ring difficult turn.
4. When installing, the arrester should be at an angle of 15~30 degrees with the vertical line, and the distance between them should not be less than 200mm.
