Abstract
The utility model relates to a lightning protection device, and particularly relates to a lightning protection device applied to a 500KV line. The lightning protection device mainly comprises a line support insulator, a first lightning arrester body and a second lightning arrester body, wherein both ends of the line support insulator are connected with a wire and the first lightning arrester body by adopting standard line hardware, the first lightning arrester body and the second lightning arrester body adopt flexible connection therebetween, and the second lightning arrester body and an extension insulator adopt flexible connection therebetween and then the second lightning arrester body is connected with a tower through the extension insulator. The lightning protection device provided by the utility model realizes installation of a 500KV line lightning arrester in a middle phase, and solves that the lightning arrester has a good stress state in the operating process and satisfies a safe distance between a lightning arrester operation high-voltage terminal and a grounding body of the tower in the aspect of electrical appliances, thereby ensuring safe operation of the lightning arrester, and making contributions to lightning protection for the domestic 500KV line and reducing the tripping rate.
Description
Technical field
The utility model relates to a kind of lightning-protection device, more particularly, relates to a kind of lightning-protection device for 500KV.
Background technology
500KV insulator supporting gap leakage conductor is arranged on two limit phases of shaft tower conventionally, because product structure is longer, if the requirement that is difficult to guarantee product mechanical performance and electric property is installed in the middle usual method that adopts on mutually, therefore middle install on mutually lightning arrester to the operation of 500KV line security by significant.
Summary of the invention
The deficiency existing in order to overcome prior art, the utility model object is to provide a kind of lightning-protection device for 500KV.This lightning-protection device has solved the problem of lightning arrester bearing tension in running well, aspect electrical equipment, met lightning arrester operation high-pressure side to tower grounding body safe distance requirement, thereby guaranteed the safe operation of 500KV circuit.
In order to realize foregoing invention order, solve the existing problem of prior art, the technology that the utility model is adopted
Scheme is: a kind of lightning-protection device for 500KV; mainly comprise circuit supporting insulator and first and second lightning arrester body; described circuit supporting insulator two ends adopt respectively the line hardware of standard to be connected with wire and the first lightning arrester body; between described the first lightning arrester body and the second lightning arrester body, adopt and be flexible coupling, described the second lightning arrester body is connected with shaft tower by extending insulator with extending to adopt between insulator after being flexible coupling again.
Described circuit supporting insulator and line insulator spacing are 5.5-6.5m.
Described circuit supporting insulator and shaft tower spacing are at least 3.6m.
The utility model beneficial effect is: a kind of lightning-protection device for 500KV; mainly comprise circuit supporting insulator and first and second lightning arrester body; described circuit supporting insulator two ends adopt respectively the line hardware of standard to be connected with wire and the first lightning arrester body; between described the first lightning arrester body and the second lightning arrester body, adopt and be flexible coupling, described the second lightning arrester body is connected with shaft tower by extending insulator with extending to adopt between insulator after being flexible coupling again.Compared with the prior art, the utility model has been realized the installation of 500KV leakage conductor in middle phase, is all guaranteeing the safe operation of lightning arrester aspect electrical machinery two, is domestic 500KV line thunder protection, reduces trip-out rate and contributes.
