Description
Technical field
The utility model relates to a kind of arrester, specifically a kind of Novel lightning arrester for power distribution network.
Background technique
Arrester is continued for protecting electrical equipment against high transient overvoltage and endangering and limit time of afterflow and also often limit
Flow a kind of electric appliance of amplitude.For any outer gap necessary to the electric appliance normal function when this term includes operation installation,
Regardless of its whether a component as a whole, arrester is generally connected between power grid conducting wire and ground wire, however sometimes
It is connected to by electric appliance winding or between conducting wire, arrester is otherwise referred to as over-voltage protector, overvoltage limiter, and arrester is
The communications cable prevent thunder and lightning when damaging through frequently with the important equipment of another kind.
It needs to be applied to arrester when protecting damage of the power distribution network from lightning stroke, prior art discloses Patent No.:
A kind of power distribution network arrester of CN201820370000.4 melts meltable support column using power frequency short circuit current, loses
As former state, fixed both ends of the shaft is drawn inside for the spring-return of support, is detached from arrester from fixator, and arrester, which turns over, to be fallen, when lightning-arrest
Device turns over backwardness, and power distribution network loses the protection of arrester in the non-maintenance period, it is possible to will appear thunder and lightning, cause power distribution network paralysed
Paralysis causes huge property loss, and therefore, those skilled in the art provide a kind of Novel lightning arrester for power distribution network, with solution
Certainly the problems mentioned above in the background art.
Summary of the invention
The purpose of this utility model is to provide a kind of Novel lightning arresters for power distribution network, to solve above-mentioned background technique
The problem of middle proposition.
To achieve the above object, the utility model provides the following technical solutions:
A kind of Novel lightning arrester for power distribution network, including it is connecting plate, fixed plate one, fixed plate two, fixed plate three, lightning-arrest
