A power system detection communication system provided with a second filter

Abstract

The invention discloses a power system detection and communication system provided with a second filter, which includes two power detection devices with the same frequency; the signal output terminals of the two power detection devices are connected with two input signals of a combiner The signal output terminal of the combiner is connected with a communication device; the communication device sends the signal coupled by the combiner to the ground analysis center for analyzing the power signal; through the excellent design of the combiner, the The output signals of the two sets of power detection equipment are combined, which has strong resistance to electric field interference and realizes low-cost power detection.

Description

technical field [0001] The invention relates to a power system detection communication system provided with a second filter. Background technique [0002] At present, there are many detection equipments, such as: application number 200910079341.1; The detection environment is very complex. If you want to save costs and use two detection devices to combine and then transmit, the requirements for the combiner are very high. It is necessary to control the electrical performance such as phase difference and return loss within an excellent range; moreover, Among them, in order to prevent the influence of the electric field environment as much as possible, the combiner should have the input signal and the output signal on the same side, so a new combiner that can realize the input and output can be set on the same side and can reduce the phase difference and return loss A combiner controlled within an excellent range is the solution to the problem of combining multiple channels i...
