Problems solved by technology
[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 The combiner controlled within an excellent range is the solution to the problem of multi-channel integration in the communication system

The invention discloses a detection communication system for a power system, and the system comprises two power detection devices at the same frequency. The signal output ends of the two power detection devices are respectively connected with two signal input ends of a combiner. A signal output end of the combiner is connected with a communication device. The communication device enables a coupled signal of the combined to be transmitted to a ground analysis center for analyzing a power signal. Through the excellent design of the combiner, the system achieves the combination of output signals of two groups of power detection equipment, is strong in resistance disturbance of the electric field, and achieves low-cost power detection.
Description
technical field [0001] The invention relates to a power system detection communication system. 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 in a communication system.
