The present invention relates to an eco-friendly lightning arrester integrated with a lead wire.

Generally, the distribution line protects various electric power equipment from an abnormal voltage such as induction lightning, direct lightning, surge, etc., and installs a lightning arrester to block the slave current and keep the system in a normal state.

The lightning arrester includes a lightning arrester module configured to perform non-pore discharge by applying an insulator, that is, a zinc oxide element having excellent nonlinearity, and a housing surrounding the lightning arrester module as an outer insulator.

However, in the conventional surge arrester, since the outer insulating housing is made of synthetic rubber such as ceramic or ethylene propylene rubber (EPDM), a housing made of ceramics causes secondary scattering due to explosion due to various factors And it was difficult to assemble or handle and transport. Further, ceramic or synthetic rubber, which is a housing of a conventional lightning arrester, has a problem that industrial waste is generated at the time of disposal to cause environmental pollution.

Also, when the housing is used as a ceramic or synthetic rubber in the course of manufacturing a conventional lightning arrester, a separate assembly procedure or a forced insertion method is applied, which makes it difficult to work and the housing is torn And the like.

The structure of the conventional lightning arrester includes a connection terminal to be fastened with a bolt on the upper side and a lead terminal for fixing the conductor of the lead wire from the bolt and the nut to the upper portion of the connection terminal, Respectively.

However, in the related art, since the conductor of the lead wire is inserted into the lead terminal of the lightning arrester and the bolts and nuts are tightly coupled to each other, it is difficult to work and if the assembly is wrong, the conductor of the lead wire may be detached from the lightning arrester. The conductor of the lead wire is dropped off due to a loosening phenomenon of the nut, and the wire is broken. Furthermore, since the airtightness of the interface due to the assembly of different materials can not be guaranteed, rainwater or moisture penetrates to cause equipment accidents such as thermal runaway, and when the insulation cover of the lightning arrester is detached or detached, There was a problem.

The electric pole and the housing are hermetically sealed to prevent a safety accident or a bird accident, Lead wire-attached polymer lightning arresters are known.

However, in the case of the above-mentioned prior art registration model No. 229020, since the insulating cap itself is formed of a rubber material only in the lightning arrester body so that the lead wire is integrally formed, industrial waste is generated at the time of disposal, The conventional problem of causing the problem to occur remains unchanged.

In the case of the above-mentioned prior art registration model No. 454411, since the lead wire is fixed in contact with the housing but is fixed not only by mutual surface contact but also by being interposed between the conductor of the lead wire and the connecting electrode, There is a problem that a short-circuit accident occurs due to separation from the housing.

In addition, since the lightning arrester assembles the lead wire to the connection electrode of the lightning arrester, then the lead wire is flexed in various directions or moved forcibly in the process of installing it on the electric pole as a finished product, so that the lead wire conductor and the connecting electrode are bent, Or the like, and the conductor of the lead wire is disconnected.
