Summary of the invention:
Purpose of the present invention is exactly at above-mentioned deficiency, and a kind of novel mesohigh system built-in fiber temperature signal transmission device is provided, this device can not only guarantee the signal transmission accurately, safety is with reliable, and simple structure, is convenient to make.
Novel mesohigh of the present invention system built-in fiber temperature signal transmission device, comprise the insulator that encases primary cut-out or other electrical equipment dut temperature contact or main circuit electric conductor, it is characterized in that encapsulating or being embedded with in the described insulator built-in fiber, one end of built-in fiber and the power valve close-coupled of signal Processing change-over circuit, the other end and low-pressure side receiving tube close-coupled.
Advantage of the present invention: the one, because power valve is positioned at the high-pressure side, receiving tube is positioned at low-pressure side, and built-in fiber can be crooked, increased insulation distance in limited space, so can improve dielectric strength, guarantees good potential isolation of high and low pressure side and safe operation.The 2nd, tube-launched signal is transferred to receiving tube by built-in fiber, and signal is not subjected to the interference of external interference signal in the built-in fiber internal transmission, thereby can guarantee the accurate and reliable of signal transmission.The 3rd, because fiber package or be embedded in the insulator body, so, still guarantee high dielectric strength in plum rain season or the bigger climatic environment of humidity.
