Abstract

一种有监测控制保护转换功能的恒电位仪,有一控制电源和电位测量器,其特征是在控制电源与电位测量器之间串联一监测控制器。本实用新型可监测参比电极的电位,如参比电极与被保护体之间的电位差偏离正常值或断路或短路,则监测控制器可切断电源或转换成其它安全保护控制模式,从而避免更大损失,大大提高了恒电位仪的可靠性。

Description

一种具有监测控制保护转换功能的恒电位仪
技术领域
本实用新型涉及一种具有监测、控制、保护、转换功能的恒电位外加电流保护装置。
背景技术
恒电位仪是恒电位外加电流保护装置的关键部件,通常由控制电源和电位测量器组成。工作时,它的一极连接一辅助电极,另一极通过电位测量器与一参比电极相连,辅助电极和参比电极固定在被保护体中。电位测量器把测量的信号反馈给控制电源,从而达到恒电位控制的目的。参比电极是恒电位外加电流保护装置的电位参考部件,常常因参比电极电位产生漂移,使被保护体电位偏离正常电位,有时也因参比电极的断路或短路使装置失控。
发明内容
本实用新型的目的是提供一种有监测、控制、保护、转换功能的恒电位仪,它能克服现有装置的上述缺点。
一种有监测控制保护转换功能的恒电位仪,有一控制电源和电位测量器,其特征是在控制电源与电位测量器之间串联一监测控制器。本实用新型可监测参比电极的电位,如参比电极与被保护体之间的电位差偏离正常值或断路或短路,则监测控制器可切断电源或转换成其它安全保护控制模式,从而避免更大损失,大大提高了恒电位仪的可靠性。
附图说明
附图为本实用新型的结构示意图。
具体实施方式
本实用新型有一控制电源1和电位测量器2,在两者之间串联一监测控制器3。使用本实用新型时,控制电源1的一极连接一辅助电极4,另一极通过电位测量器2与一参比电极6相连,将辅助电极4和参比电极6固定在被保护体5中,并将控制电源1和电位测量器2用导线与被保护体5连接起来。
本实用新型的监测控制器3一端监测参比电极6与被保护体5之间的电位,另一端接控制电源1;其作用是:当参比电极6与被保护体5之间的电位异常时,该监测控制器3可切断电源或由恒电位控制转换成其它安全保护控制模式。
