Abstract
The utility model relates to a thermal explosion releasable arrester used for an outdoor AC (alternating current) high-voltage line. The thermal explosion releasable arrester comprises a composite insulator and the arrester, wherein an upper fixed rack is arranged at the upper end of the composite insulator, and a lower fixed rack is arranged at the lower end thereof; an upper jointing clamp is arranged on one side of the upper fixed rack; an upper elastic reed is arranged on the other side of the upper fixed rack; a lower jointing clamp is arranged on one side of the lower fixed rack; an lower elastic reed is arranged on the other side of the lower fixed rack; an upper moving contact is fixed between a clamping cap and the upper elastic reed; the lower end of the upper moving contact is connected with the upper end of the arrester; a thermal explosion disconnector is connected to the lower end of the arrester; the upper end of the thermal explosion disconnector is hinged with a lower moving contact; and a metal tape is arranged between the lower end of the thermal explosion disconnector and the lower moving contact. Power off and working highly above the ground are no needed in the mounting of the thermal explosion releasable arrester; and the arrester on the line can be assembled or disassembled on the ground by using an insulating rod. Therefore, the workload for detecting, dismounting or replacing the arrester is greatly reduced, and the reliability rate of power supply is improved. Besides, the thermal explosion releasable arrester can drop automatically when being struck by lightning, can be spotted easily and timely, and saves the time to find fault point.
Description
Technical field
