PROBLEM TO BE SOLVED: To provide a battery-less voltage detection indicator for electric fences in which an impulse voltage applied to an electric fence line can be indicated even under the brightness of daytime (under sunlight).SOLUTION: When an impulse voltage is applied between the ground (E1) and a voltage detection unit (K1) and is divided by R1 - R6 and the voltage of (R6, R5, R4) reaches a lighting starting potential (normally, about 80 v) of neon tubes (NE3, NE2, NE1), the neon tubes are turned on and an electric current is made to flow and are rectified in diodes of (D1, D2, D3), and the electric current is made to flow to the light emitting diodes (LED1, LED2, LED3) connected to the positive sides (+) and the negative sides (-) of the diodes of the (D1, D2, D3), and thereby the light is emitted.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2017,JPO&INPIT【課題】電気牧柵線に印加されている衝撃電圧を昼間の明るい(太陽光線下)でも表示が可能な電池レス電気牧柵用電圧検知表示器を提供すること。【解決手段】 大地(E1)と電圧検知部(K1)との間に衝撃電圧が印加されR1~R6で分圧され(R6,R5,R4)の電圧がネオン管(NE3,NE2,NE1)の点灯開始電圧(通常80v程度)に達するとネオン管が点灯し電流が流れ(D1,D2,D3)のダイオードで整流され(D1,D2,D3)のプラス(+)マイナス(-)に接続された発光ダイオード(LED1,LED2,LED3)に電流が流れ発光する。【選択図】図3
