Abstract
The utility model relates to a combined type compound jacket zinc oxide arrester which comprises an arrester, an action counter, a detachment device and an insulating bracket, wherein the arrester is a compound jacket zinc oxide arrester; an upper end of the action counter passes through one end of the insulating bracket and then is connected with a lower end of the arrester; the lower end of the action counter is connected with the upper end of the detachment device; and the lower end of the detachment device is connected with a ground lead. Compared with the prior art, the combined type compound jacket zinc oxide arrester has the advantages that the daily monitoring for the arrester is convenient, the response is quick, the arc extinguishing effect is good, the breaking capacity is strong, no power outage is caused, the working reliability is high, the volume is small, the weight is light, the sealing property is excellent, an obvious mark is supplied to a fault arrester, and a maintainer can quickly find a fault point and can timely maintain and replace the arrester.
Description
Technical field
The utility model relates to a kind of lightning arrester in the electrical engineering technical field, is specifically related to a kind of combined overcoat zinc oxide arrester.
Background technology
At present, be used for lightning arrester that the electric equipment that moves at power network is protected, be sitting type structure; When lightning arrester self breaks down; Can not be out of service from power network automatically because of it, often cause power network to pass through the ground short circuit situation that lightning arrester and pedestal and the earth are connected, so that lead to the large-area pernicious power outage of power network; And mark can not be provided, be not easy to the attendant and find the fault point.
The utility model content
The purpose of the utility model is exactly the defective that exists to prior art, and a kind of combined overcoat zinc oxide arrester is provided.
Its technical scheme is: comprise lightning arrester, operation counter, disconnector and insulating support, lightning arrester is the composite sheath zinc oxide arrester.The lower ends that the upper end of said operation counter is passed behind the end of insulating support with lightning arrester connects, and the lower end of operation counter is connected with the upper end of disconnector, and the lower end of disconnector is connected with ground lead.
Wherein, said operation counter is a JSQ-10 type discharge counter.
The utility model compared with prior art, the advantage that has is: be convenient to the daily monitoring to lightning arrester, reaction is fast; Arc quenching effect is good, and breaking capacity is strong, does not cause power failure; Functional reliability is high, and volume is little, in light weight, good airproof performance; For the fault lightning arrester provides the visible marking, be convenient to the attendant and find fault point and in time keep in repair and change rapidly.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
With reference to Fig. 1, a kind of combined overcoat zinc oxide arrester comprises lightning arrester 1, operation counter 2, disconnector 3 and insulating support 4, and lightning arrester 1 is the composite sheath zinc oxide arrester.The lower ends that the upper end of operation counter 2 is passed behind the end of insulating support 4 with lightning arrester 1 connects, and the lower end of operation counter 2 is connected with the upper end of disconnector 3, and the lower end of disconnector 3 is connected with ground lead 5.Wherein, operation counter 2 is a JSQ-10 type discharge counter.
During use, the other end of edge support 4 is fixed on the overhead line structures, the upper end of lightning arrester 1 connects AAA, and ground lead 5 is connected with ground wire or metallic circuit shaft tower and gets final product.When lightning arrester 1 under abnormal conditions; Because when the stability that fault current causes lightning arrester 1 to move automatically was damaged, the disconnector 3 in the utility model promptly can come off rapidly automatically, make ground lead 5 automatic and ground connection disengagements; Fault lightning arrester 1 is withdrawed from rapidly from network system; Guarantee uninterrupted power supply, and give the lightning arrester that is out of order with visible disengaging sign, greatly facilitate the attendant and find the fault point rapidly, and in time carry out maintain and replace through operation counter 2.
Claims (2)
1. combined overcoat zinc oxide arrester; Comprise lightning arrester, operation counter, disconnector and insulating support; Lightning arrester is the composite sheath zinc oxide arrester; It is characterized in that: the lower ends that the upper end of said operation counter is passed behind the end of insulating support with lightning arrester connects, and the lower end of operation counter is connected with the upper end of disconnector, and the lower end of disconnector is connected with ground lead.
2. combined overcoat zinc oxide arrester according to claim 1 is characterized in that: said operation counter is a JSQ-10 type discharge counter.
