Abstract

본 발명은 브이시알 시스템의 전원 이상시에 해당 전원부를 차단 제어하는 수단에 관한 것으로서, 종래에는 이러한 브이시알 시스템에서 다수의 회로기판에 제각기 공급되는 다수의 주전원 트랜스 2차측 전원부에 이상이 있을때에 이에 대한 감지수단 및 적절한 조처를 강구할 수 있는 수단이 구비되어져 있지 않아 이러한 시스템 이용의 안전성 확보에 문제가 되어왔다,[0001] The present invention relates to a means for shutting off and controlling a corresponding power source when a power source of a Vishal system is faulty. In the conventional Vishal system, when a plurality of main power transformer secondary power sources are supplied to a plurality of circuit boards, There is no provision of means for sensing means and appropriate measures, which has been a problem in securing the safety of using such a system.

본 발명은 종래의 이러한 문제점을 개선할 수 있도록 상기 주전원 트랜스(22)이 2차측 전원부에서 시스템 마이크로 컴퓨터(31)구동의 2차측 전원부외의 2차측 전원부(21)에 제각기 설치되어져 있는 과전류 감지수단(11,12)과 2차측 전원부의 입력측에 설치되어져서 과전류 감지수단(11,12)으로 감지된 과전류 상태에 따라 소정2차측 전원부의 구동을 차단하는 제어 동작의 마이크로 컴퓨터(31)와, 이 마이크로 컴퓨터(31)의 제어하에 2차측 전원부의 입력을 차단하는 릴레이 수단(13,15)과, 상기 과전류 감지수단(11,12)으로 과전류가 발생되었을때 이를 외부로 표시하여 주는 디지트론(16)등을 포함한 구성으로 이뤄져 있는 브이시알의 전원이상 경고표시 시스템을 제공하는데 있다.In order to overcome such a problem, the present invention is characterized in that the main power transformer 22 is connected to an overcurrent detecting means (not shown) provided in the secondary side power source unit 21 other than the secondary side power source unit driven by the system microcomputer 31 in the secondary side power source unit And a control microcomputer 31 installed at an input side of the secondary side power supply unit to cut off the driving of the predetermined secondary side power supply unit according to the overcurrent state sensed by the overcurrent sensing means 11 and 12, Relay means 13 and 15 for shutting off the input of the secondary power source under the control of the computer 31 and a digital transistor 16 for indicating the overcurrent to the outside when the overcurrent sensing means 11 and 12 generate an overcurrent. And the like. The present invention also provides a warning system for displaying a power abnormality of a Vishal.
