Switch cabinet operation state management monitoring system and method, and computing device

Abstract

The invention discloses a switch cabinet operation state management monitoring system and method and a computing device. The method comprises the steps of monitoring a grounding knife-switch state, ahandcart position and arc light; in the grounding knife-switch state monitoring process, the current position of the grounding knife-switch is identified through the grounding knife-switch image collected by the first image collection device at present, and whether the grounding knife-switch is in an opening state or a closing state at present is judged; in a handcart position monitoring process,the position of the handcart is identified through the handcart image currently acquired by the second image acquisition equipment, and whether the handcart moves to an opening or closing state or notat present is judged; in the arc light monitoring process, whether the arc light phenomenon occurs currently or not is judged according to the comparison result of the gray feature value between thecontact image, collected by the third image collection device currently, of the switch cabinet without illumination and the contact image, collected by the third image collection device, of the arc light phenomenon; the operation state of the switch cabinet is monitored in real time in a non-contact mode, and accurate monitoring of the operation state of the switch cabinet can be achieved.

Description

technical field [0001] The invention belongs to the field of electric power measurement, and in particular relates to a management and monitoring system, method and computing equipment for the operating state of a switchgear. Background technique [0002] Switchgear is an important electrical equipment in the power system. It plays the role of opening and closing, controlling and protecting electrical equipment in the process of power system power generation, transmission, distribution and power conversion. It is used in power plants, substations, petrochemical, There are a large number of applications in various occasions such as metallurgy and steel rolling, light industry textiles, factories and mines, residential quarters, and high-rise buildings. [0003] The interior of the switchgear contains circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. During the opening and closing process, each device needs to c...

AI Technical Summary

Problems solved by technology

During the opening and closing process, each device needs to cooperate with each other to complete the opening and closing of the switch. If the equipment fails or the coordination is not in place, it will cause the switch cabinet to fail, causing equipment and personnel injury. Therefore, it is very necessary to check the operating status of the switch cabinet. real-time monitoring

[0004] At present, the monitoring of the operating state of the switchgear mainly relies on various electrical sensors, which rely on monitoring various electrical signals to indirectly determine the working state of the switchgear, and the amount of monitored states is small and the visibility is poor.
