YH5WS Removable arrester

• The detachable arrester is a modified zinc oxide arrester for power distribution, which is cleverly installed on the drop-out structure of the drop-out fuse, so that the arrester can be easily detected with the help of an insulated pull-gate operating rod under the condition of uninterrupted power supply. Maintenance and replacement not only ensure the smooth flow of lines, but also greatly reduce the work intensity and time of power maintenance personnel. It is especially suitable for places that are not suitable for power outages such as post and telecommunications, airport stations, hospitals, and bustling commercial areas. The other performance of the product is the same as that of the power 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 operate, so that the grounding terminal of the disconnector is automatically disconnected, the arrester component falls, and exits operation to prevent further accidents. It is easy for maintenance personnel to find out and repair and replace in time. The falling principle is similar to that of a fuse fuse blowing and causing a fuse tube to fall. Our company uses the most advanced RW12 road fall mechanism in the world, which is reliable in contact, flexible in opening and closing, and advanced accessories of stainless steel cover with composite pillars. It has anti-fouling, fast action, wide current range, and can withstand The advantages of being. subjected to the specified current impact and operating load. Product performance meets the national standard GB11032-2000 (eqvIEG60099-4:1991) "AC Gapless Metal Oxide Surge Arrester", JB/T8952-2005 "Composite Jacket Gapless Metal Oxide Surge Arrester for AC System", GB311.1-1997 " Insulation coordination of high-voltage power transmission and transformation equipment"

 USE ENVIRONMENTAL CONDITION

• Ambient temperature: -40°C~+40°C;
• The altitude is not more than 3000m;
• Power frequency: 48Hz-62Hz;
• The maximum wind speed does not exceed 35m/S;
• Earthquake intensity 7 degrees and below areas.

 STRUCTURAL FEATURES

• The arrester unit can be loaded and unloaded at any time when the power is on, which is especially suitable for places where power failure is not suitable
• With a disconnector, when the arrester unit fails, it can automatically fall down and exit operation to ensure the normal passage of the line.
• Due to the failure of the unit, the unit will fall down to form an obvious sign, which is easy to find and repair and replace in time.
• The lightning arrester adopts a composite jacket, and the drop mechanism adopts a composite pillar, which has good water repellency and strong pollution resistance.

• 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.
• Before installation and use, please check the tightness between the arrester components and the drop mechanism to ensure good contact and flexible handling.
• Adjustment method: Turn the copper contact (with pull ring) on the arrester to make the opening tension within 6-10kg, and keep the copper contact pull ring side facing outward, and then tighten the lower nut to make the pull ring difficult to rotate
• When installing, make the arrester and the plumb line form an angle of 15-30 degrees, and the distance should be at least 200mm.
