Specific embodiment
With reference to the accompanying drawing and the utility model is described further in specific embodiment.
Embodiment 1：As shown in Fig. 1-Figure 10, a kind of counter device for the replacement that do not have a power failure for arrester, including electric discharge
The power end of counter 1, discharge counter 1 is connected on connection conductor 5 by disconnecting link 1, and ground terminal is connected by disconnecting link 33
To ground wire 4, disconnecting link 26 is connected between ground wire 4 and connection conductor 5, connection conductor 5 is fixedly connected on insulator foot 14, insulate
Arrester 15 is installed, insulator foot 14 passes through fixed bracket 16 and is fixedly connected on electric pole 8 above pedestal 14.
Preferably, above-mentioned disconnecting link 1, disconnecting link 26 and disconnecting link 33 are fixedly connected in mounting box 7, and mounting box 7 is fixed to be connected
