The high-voltage switch characteristic detection system comprises a high-voltage switch (circuit breaker); the output end of the high-voltage switch (circuit breaker) is connected with a CCD camera; the output end of the CCD camera is connected with an image acquisition device; the image acquisition device is connected with a computer; the output end of the CCD camera is also connected with a TTL flip-flop; the TTL flip-flop is connected with a switch signal detector; the input end of the switch signal detector is connected with the high-voltage switch (circuit breaker); the output end of the switch signal detector is connected with a timing connecting device; the output end of the timing connecting device is connected with the computer; the output end of the computer is connected with a switch control power source; the output end of the switch control power source is connected with a tripping coil; the tripping coil is in linkage with the normally-closed contact of the high-voltage switch (circuit breaker); and the computer is connected with a parameter calculation module and a relational database, and is provided with a communication interface, and is connected with a display device. According to the high-voltage switch characteristic detection system of the invention, advanced control equipment is adopted, so that detection can be more accurate.

Description

technical field [0001] The invention relates to the technical field of high-voltage switch detection in power systems, in particular to a high-voltage switch characteristic detection system using image measurement technology. Background technique [0002] With the continuous expansion of the scale of the power system and the deepening of the power control technology, various high-voltage switches and other on-off control devices are more and more widely used. When the power system is running normally, it is used to switch the operation mode, connect the equipment or line to the circuit or exit the operation, and play a control role; when the electrical equipment or line fails, the circuit breaker is used to quickly remove the fault to ensure that the non-faulty part is normal Run and protect. It can be seen that the high-voltage switch plays an extremely important role in the opening and closing of the operation and the breaking of important loads. When there is an abnorma...
