The utility model discloses a novel
lightning arrester with stable structure relates to
lightning arrester technical field, including insulating installation base, the top of insulating installation base is installed with
lightning arrester body, the top of
lightning arrester body is installed with equalizing ring through connecting mechanism, and the top of connecting mechanism and
lightning arrester body are connected in cooperation, and the top of connecting mechanism is inserted with the
protection mechanism for the protection of the top of connecting mechanism and is matched with the
protection mechanism. The utility model discloses through the setting of connecting mechanism can increase the convenience of the connection between
lightning arrester body and equalizing ring, through the collapsible connecting mechanism increases the convenience of the device in the transportation process, avoids the collision in the transportation process and leads to the deformation of equalizing ring and connecting mechanism, influences the
assembly of device later period, in addition, the connecting mechanism that can expand can increase the connection cooperation degree between connecting mechanism and equalizing ring, and can improve the stress uniformity of equalizing ring, increases the overall stability and use intensity of device.
