Abstract
The utility model discloses a drop-out lightning arrester and relates to the technical field of electrical equipment. The drop-out lightning arrester comprises a post insulator and a lightning arrester main body. The top of the post insulator is connected with the top of the lightning arrester main body by a top connecting plate. The bottom of the post insulator is connected with the bottom of the lightning arrester main body by a bottom connecting plate. The bottom of the lightning arrester main body is connected with a disengaging device which is connected with a screw rod. The bottom of the screw rod is connected with the bottom connecting plate by a drawing wire through a drawing ear. The top of the top connecting plate is connected with a fixed terminal. The top of one end of the fixed terminal is connected with a binding post. A contact is disposed between the top of the lightning arrester main body and the top connecting plate and is connected with a conductive board. The binding post is configured in an L shape and is fixed on the fixed terminal and the top connecting plate through a bolt. A wire connecting bolt is disposed on the binding post. The drop-out lightning arrester has characteristics of a simple structure and reasonable design. The binding post is designed in an L shape while the bottom connecting plate is designed in a Z shape so that stable operation is guaranteed and reliable dropping speed is achieved.
Description
Technical field
The utility model relates to electrical equipment technical field, is specifically related to a kind of drop type lightning arrester.
Background technology
Lightning arrester is the important overvoltage protection of electric power system, will cause line tripping and damage power transmission and transforming equipment once occur damaging; And because lightning arrester regular maintenance and damage back dismounting also will have a power failure; All can cause huge direct and indirect economic loss every year.So how to make line outage out of service and unlikely automatically after the lightning arrester fault, can find the lightning arrester of fault easily and can not have a power failure and change easily, be to need the further problem of research at present.Constantly there were the device research and development of various novel lightning arresters to use in recent years, denomination of invention is " detached type lightning arrester ", the patent No. is: the Chinese utility model patent of ZL00220510.6 has been introduced a kind of arrester device, it is characterized in that adopting porcelain vase pillar two ends that upper and lower static contact is installed fixes with the lightning arrester of going up lower moving contact, have and can adopt insulating bar under situation about not having a power failure, to load and unload its lightning arrester advantage partly, but when having fault lightning arrester can not break away from automatically, shortcoming such as the difficult discovery of fault lightning arrester.All there are some problems in present release unit both domestic and external, has certain limitation.
