Drop Arrester

　Summarize

Removable arrester is a kind of smart installation of distribution type zinc oxide arrester on the drop-type structure of the drop-type fuse after refitting, so that the arrester can be detected, repaired and replaced conveniently with the help of insulated pull-out lever without power failure. It not only ensures the unimpeded line, but also greatly reduces the work intensity and time of power maintenance personnel, especially. Suitable for places not suitable for blackouts, such as post and telecommunications, Airport stations, hospitals, busy business districts, etc. The other performance of the product is the same as that of the distribution type lightning arrester. The second generation dropping arrester adds disconnectors. When the arrester occurs abnormally, the disconnectors are operated by short circuit current of power frequency, which makes the grounding end of the disconnector automatically disconnect, the components of the arrester fall off, and withdraws from operation to prevent further enlargement of the accident. It is easy for maintenance personnel to find out in time for maintenance and replacement. Its turnover principle is similar to that caused by fuse fuse fuse. 。Our company adopts the most advanced RWl2 type road falling mechanism in the world at present, which has reliable contact, flexible splitting and closing, and advanced accessories of stainless steel cover with composite pillars. It has the advantages of anti-fouling, fast action speed, wide current range, and can withstand specified current shock and action load. The product performance meets the national standard GB11032-2000 (eqvlEC60099-4:1991), "AC Gapless Metal Oxide Arrester", JB/T8952-2005 "Composite Coat Gapless Metal Oxide Arrester for AC System", GB311.1-19

Conditions of use

1. Ambient temperature: -40℃~40℃；
2. The altitude is not more than 3000m；
3. Power supply frequency: 48Hz~62Hz；
4. Maximum wind speed not exceeding 35 m/s；:
5. Areas with seismic intensity of 7 degrees or less.

Characteristic

1. The arrester unit can be loaded and unloaded at any time when it is electrified. It is especially suitable for places where power failure is not appropriate.
2. With disconnector, the arrester unit can automatically fall down and withdraw from operation when it breaks down, so as to ensure the normal passage of the line.
3. When the unit falls down due to the fault, it forms obvious signs, is easy to find, and can be repaired and replaced in time.
4. The lightning arrester adopts a composite coat and the drop mechanism adopts a composite pillar, which has good hydrophobicity and pollution resistance.

Product Model Description

Product parameters

Note: The parameters of lightning arrester are the same as those of conventional lightning arrester. The above type is distribution type and can be replaced by other types
such as capacitive type.
