Thread Content

Recently, the patent for “A Metal Oxide Arrester and Its Manufacturing Method”, applied for by Jiangdong Fittings Equipment Co., Ltd. and Jiangsu Zhongtian Technology Co., Ltd., was granted. The abstract indicates that this invention discloses a metal oxide arrester and its manufacturing method, which falls within the field of high-voltage electrical equipment. It comprises a connection frame, insulating pull rods, and at least two arrester units; these arrester units are connected to the connection frame. The connection frame consists of a rotating frame at the bottom and a crossbeam frame at the top. The rotating frame has mounting positions for the bottom ends of the arrester units, while the crossbeam frame is equipped with elastic conductive components against which the top ends of the arrester units rest. The top part of each arrester unit is confined by an insulating pull rod, and one or both ends of this insulating pull rod are fitted with pull rings. Multiple lightning arresters are installed, and they can be replaced using a rotating frame and insulating pull rods; these rods can be pulled from the ground, enabling quick replacement in case of damage during adverse weather conditions or at critical locations, thus allowing for rapid restoration of the circuit protection function.
