高压蒸汽消毒器用调功定时器的研制

本文给出了用于控制高压蒸汽消毒器的调功定时器的设计方案。主电路采用双向可控硅作为无触点开关,控制回路彩用过零触发技术,从而实现了高压蒸汽消毒器的加热功率的控制。定时器部分采用减计数定时电路,可实现定时消毒并具有消毒完成后自动断开主回路电源及报警功能,从而确保消毒过程的正常进行。

The researching and making about regulating power timer of pressure steam disinfecting apparatus

The design of regulating power timer being used for pressure steam disinfecting apparatus is discussed in this article. BCR in the main electronic circuit and technology of over zero triggering in the loop is used in oredr to control heating power of steam disinfecting apparatus. The subtrahend timer time disinfecting and automatically relay loop and automatically alarm after finishing disinfecting.
