●Outline
Drop (can be cast type, removable) is the distribution type arrester MOA after modification cleverly mounted on drop-out fuse drop-out mechanism, to continue in the case of electricity, can make use of insulated wind up manipulating lightning rod for easy detection, repair and replacement, not only to ensure the smooth flow of lines, but also greatly reduces the electricity maintenance personnel work intensity and duration, not particularly suited to places such as the blackout telecommunications, airports, railway stations, hospitals, downtown business district and so on. Other performance products with distribution arresters.
The second generation increased from fall arrester, a fault occurs when an exception occurs in the arrester using frequency short-circuit current from the device to allow movements to automatically disengage from the grounding terminal, arrester elements turn over, quit running to prevent further incidents, maintenance personnel to detect and easy to carry out maintenance and replacement. Its turn over principle similar to a fuse blown fuse caused melting tube turn over.
I am using the currently most advanced hot blast from the device, compared with traditional hot-melt-type action from having fast, wide operating current range, and can withstand shock and movement provisions of the advantages of the current load.
● Installation Instructions
Please check before installation tightness between the drop-arrester elements and agencies to ensure good contact and cast unloading flexible. Drop-body connection termination on high-voltage lines, the next terminal must be grounded, not reversed.
Arrester precautions and put into operation before being put into operation after the same distribution type arrester. When arrester need repair or replacement, you can continue to power in the case, with the insulation wind up on the joystick retractors aligned arrester unit easy to operate, as the replacement drop-melting tube.
