Embodiment Construction
[0038] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0039] The present invention is a UHV DC corona current data acquisition card based on USB transmission, and its system block diagram is as follows figure 1 As shown, it consists of a signal conditioning module, an A / D conversion module and a USB control module connected in series.
[0040] Such as figure 2 Shown is the signal conditioning module of the present invention, which is composed of a limiter protection circuit, a program-controlled amplifier circuit, an anti-aliasing filter circuit and an emitter follower circuit connected in sequence.
[0041] The limiting protection circuit includes a parallel transient suppression diode TVS and a ceramic discharge diode, which are used to limit the amplitude of the acquisition signal of the A / D conversion module and prevent the high voltage from breaking down the A / D modu...
