        Drop type (type can be cast, removable) arrester is the distribution type Zinc Oxide arrester modified smart type mechanism mounted on the drop drop type fuse, reach in the energized condition, can use the insulating pull brake lever is convenient for arrester testing, maintenance and replacement, not only to ensure the smooth lines, and greatly reduce the work intensity and time of power maintenance, especially suitable for not blackout places such as airports, railway stations, hospitals e-post, bustling commercial district, other properties of products with distribution type arrester.

       The second generation of drop type arrester increases from the device, in the lightning arrester fault occurs, the power frequency short circuit current to let out of action, the disconnector grounding terminal automatically disengaged, arrester elements fall, out of operation prevent the accident further expansion, and easy maintenance personnel found timely maintenance and replacement. The principle of falling down is similar to that of fuse fuse caused by melting and falling. Our company adopts the state-of-the-art thermal explosion disconnector at present, which has the advantages of fast action speed, wide action current range, and tolerable current impulse and action load.

1. before installation, please check the tightness between the lightning arrester components and the falling mechanism, so as to ensure good contact and flexible unloading.

2. The connection end of the falling mechanism is connected to the high voltage line. The lower connection end must be grounded reliably.

3. The matters needing attention before and after the operation are put into operation are the same as the distribution type arrester.

4. when the arrester needs to be overhauled or replaced, it can contact the insulated switch lever to operate conveniently on the arrester unit under continuous power, just like replacing the drop type melting pipe.

Note: the parameters of the arrester are the same as the conventional lightning arrester. The above is the distribution type, which can be replaced by other types of capacitance.
