The phase angle setting circuit includes two dial switches 2, two triodes, and three key switches. The two dial switches are K21 and K22, and the two triodes are V1 and V2, the three key switches are K23, K24 and K25, and the data calculation and waveform compilation circuits are single-chip integrated circuits. The present invention greatly shortens the detection time, reduces the labor intensity of employees, improves work efficiency, improves test accuracy and correctness, and can The conversion of the generated square wave and sine wave plays a positive role in promoting the development of grid intelligent construction management technology.

Description

Technical field: [0001] The invention relates to a signal generating device, in particular to a three-phase, two-waveform adjustable phase-angle signal generating device for a power system. Background technique: [0002] At present, the development of society is advancing by leaps and bounds, and the society's demand for electricity is getting higher and higher, and the requirements for the stability of the power supply of the power system are also getting higher and higher. Now the construction of the power system grid, power production, scientific research, and laboratories for electrical equipment, instruments, etc. The signal generators used for testing and calibration are all single-phase, and cannot simultaneously output square waves and sine waves, which is inconvenient to use and has a great impact on work efficiency, test accuracy and correctness. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the deficiencie...
