| Power grid used in the reactor is essentially a non-magnetic materials, the hollow coil. It can be arranged as needed for the vertical, horizontal, and three kinds of assembly forms a triangle. When a short circuit in the power system will result in significant short-circuit current value. If you do not impose restrictions on the dynamics of electrical equipment to maintain the stability and thermal stability is very difficult. Therefore, in order to meet the requirement of the capacity of certain circuit breakers breaker, often in the qualifying series circuit breaker at reactor and increase the short-circuit impedance to limit short-circuit current.As a result of the reactor in the event of short circuit, the reactor voltage drop on the larger, so it played a role in the maintenance of bus voltage level, so that the voltage fluctuations on the smaller bus to ensure that the non-users on the fault line of electrical equipment Stability of operationIt is in the power system has an irreplaceable role, therefore, it corrupted the inner surface of the periodic examination is very important. The current reactor most of the inner surface detection methods are based on artificial fiber optic endoscopic detection method based, low efficiency, error rate, limited number of factors such as inadequate. Collected a huge number of images returned, there is no associated with a specific software to deal with, often the problem can not be resolved or not resolved in time. The project produced an independent can be targeted at the inner surface of hollow reactor test came back collected a large number of pictures batch system. to use software to cut pictures, pictures, scans, and even corrupted pictures machine selection, eliminating the shortcomings of artificial time-consuming, but also can effect the picture processing.The core of this paper includes a set of simple digital image acquisition program, with specific image processing system. Through the reactor inner surface of the image acquisition, preservation, and use computer software processing can be achieved on the corrupted part of picture is accurate, rapid identification, in order to protect the power system safe and efficient operation. |
