Abstract

본 발명은 네온관 교류전압인가회로 및 무부하시 고전압발생정지회로에 관한 것으로, 트랜스(TS3)에서 발생되는 고주파전압(+,-)의 크기를 감쇄기(80)로서 제2도의 (나)도와 같이 다르게 하여 네온관(90)의 방울맺힘 현상을 제거하여 균일한 빛을 발산하게 하고, 네온관(90)의 파손 또는 연결선의 단선등의 상태에서는 고전압이 계속해서 발생되므로 트랜스(TS3) 코일(L3)에 연결된 고전압발생회로(70)에 의해 고전압발생을 자동으로 정지시켜 화재 및 감전사고를 미연에 방지할 수 있다.The present invention relates to a neon tube AC voltage application circuit and a high voltage generation stop circuit at no load, and the magnitude of the high frequency voltage (+,-) generated in the transformer (TS 3 ) as the attenuator 80 as shown in (b) of FIG. By differently removing the condensation phenomenon of the neon tube (90) to emit a uniform light, the high voltage is continuously generated in the state of breakage of the neon tube (90) or disconnection of the connection line, so that the transformer (TS 3 ) coil (L 3 By the high voltage generation circuit 70 connected to the high voltage generation can be automatically stopped to prevent fire and electric shock in advance.
