COMPUTER-AIDED TESTING METHOD FOR ELECTRIC CIRCUITS OF SOPHISTICATED ENGINEERING PRODUCTS AND DEVICE FOR ITS IMPLEMENTATION

FIELD: electricity.SUBSTANCE: device comprises a computer as well as a tester of electric circuit parameters and low-voltage switch including two switch matrices for control of electric circuits without active elements or a tester of electric circuit parameters, program-controlled test input source and low-voltage switch including four switch matrices for control of electric circuits with active elements. There are also additional high-voltage tester, high-voltage switch, a harness for connection to contacts of electrical circuits in the tested facility and high-voltage harness for connection to contacts of high-voltage electrical circuits in the tested facility. At that inputs and outputs of the computer through interface main line are coupled to control inputs of the test input source, the tester of electric circuit parameters, the low-voltage switch, the high-voltage tester and high-voltage switch. Coded outputs of the tester of electric circuit parameters and high-voltage tester are connected to the computer through the interface main line. Input and body frame of the tester of electric circuit parameters are connected to common points of the first and second switch matrices of the low-voltage switch. During testing of electric circuits with active elements input and body frame of the test input source are connected to common points of the third and fourth switch matrices of the low-voltage switch. Output and input of the high-voltage tester are connected to common points of the first and second switch matrices of the high-voltage switch. The harness is connected to contacts of the switch matrices of the low-voltage switch. The high-voltage harness is connected to contacts of the switch matrices of the high-voltage switch.EFFECT: simplification of electric circuits testing.4 cl, 3 dwg
