Removable arrester

Overview:

The detachable arrester is a modified zinc oxide arrester of the power distribution type to achieve that in the case of uninterrupted power, the arrester can be easily inspected, repaired and replaced with the help of an insulated switch operating lever, which not only guarantees the line, but also greatly It reduces the work intensity and time of power maintenance personnel, and is especially suitable for places that are not suitable for power outages, such as post and telecommunications, airport stations, hospitals, and prosperous business districts. 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 the withdrawal prevents the accident from further expanding. It is easy for maintenance personnel to find out in time for repair and replacement. The falling principle is similar to that of a fuse fuse blowing and causing a fuse tube to fall. Our company adopts the most advanced RWl2 road fall mechanism in the world, which is reliable in contact, flexible in opening and closing, and adopts advanced accessories of stainless steel cover of composite pillar. It has anti-fouling, fast action, wide current range, and can withstand Specify the advantages of current impulse and operating load.

Product performance meets the national standard GB11032 (eqv IEC60099) "AC gapless metal oxide arrester", JB/T8952 "Composite jacket gapless metal oxide arrester for AC system", GB311.1 "Insulation coordination of high-voltage power transmission and transformation equipment"

Product features producteatures

1. The arrester unit can be loaded and unloaded at any time when the power is on, which is especially suitable for places where power is not suitable.

2. With a disconnector, when the arrester unit fails, it can automatically fall down and exit operation to ensure the normal passage of the line.

3. When the unit is overturned, it will form an obvious sign, which is easy to find and repair and replace in time.

4. The lightning arrester adopts a composite jacket, and the drop mechanism adopts a composite pillar, which has good water repellency and strong pollution resistance.
