Abstract

The invention relates to a partial voltage monitoring anti-interference device which comprises the components of a partial voltage monitoring system which has an input end that is connected with a to-be-tested power supply and is used for converting high voltage of the to-be-tested power supply into low voltage; the acquisition end of the data acquisition system is connected with the output end ofthe voltage division monitoring system through a signal transmission line, and the data acquisition system is used for acquiring and processing low voltage to obtain the voltage of the to-be-tested power supply; and the power supply is used for supplying power to the data acquisition system, the power supply comprises an isolation transformer, a distribution parameter attenuator and a low-pass filter, the distribution parameter attenuator comprises a first coil and a second coil, and the first coil and the second coil are both formed by winding twisted pairs. The isolation transformer and thelow-pass filter can effectively suppress interference of high and low frequencies, and the attenuator can ensure the anti-interference capability of the low-pass filter, so that interference introduced by a power supply can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to an anti-jamming device for partial pressure monitoring. Background technique [0002] Interference generally refers to noise other than useful signals, some harmful electrical changes that occur during signal input, transmission, and output, and these changes force errors or artifacts in the transmission value, indication value, or output value of the signal. Generally, interference is divided into two categories, one is the interference caused by equipment and feeder system, and the other is other interference, which can be considered as external interference. Common interferences include conducted interference and radiated interference. Among them, conducted interference refers to the interference transmitted to sensitive devices through wires, and radiated interference refers to the interference transmitted to sensitive devices through space radiation. [0003] In the data ...
