Problems solved by technology
However, the online installation of sensors and other instruments requires a lot of capital investment, and it still takes a lot of money and time in the operation and maintenance phase
Since the traditional power monitoring system is designed with "invasive" technology, it is generally necessary to conduct a short-term power outage to the power supply users during installation and maintenance, which may easily cause user dissatisfaction or other economic losses, and it is difficult to meet system optimization, energy saving, and fault detection and analysis at the same time. and other needs; it may also change the electrical performance of the monitored object and reduce the service life of the monitored object, which is contrary to the original intention of installing online monitoring

The application discloses a high-voltage switchgear with on-line monitoring and emergency functions, including a frame, and three-phase switching components arranged on the frame, and the switching components of each phase are provided with switches in different positions. The high-voltage switchgear also includes a monitoring component, an emergency component, and a control device; the monitoring component has three and is correspondingly arranged at the opening and closing components of each phase, and the monitoring component is rotatably arranged at the On the frame; the emergency component has two and is correspondingly arranged between the two-phase switching components; the control device is suitable for controlling the monitoring component to collect the operating status information of the switching component, so The control device is further adapted to control the emergency component to switch between the normal state and the emergency state according to the operating state information of the switching component. It has the advantages of being non-invasive, having a wide monitoring range, high monitoring accuracy, and being able to deal with abnormal conditions.
Description
technical field [0001] The present application relates to the field of power equipment, in particular to high-voltage switchgear. Background technique [0002] In recent years, the online monitoring technology of high-voltage switchgear in the power system transmission and distribution network has been a research hotspot in the industry. break direction. However, the online installation of sensors and other instruments requires a lot of capital investment, and it still takes a lot of money and time in the operation and maintenance phase. Since the traditional power monitoring system is designed with "invasive" technology, it is generally necessary to conduct a short-term power outage to the power supply users during installation and maintenance, which may easily cause user dissatisfaction or other economic losses, and it is difficult to meet system optimization, energy saving, and fault detection and analysis at the same time. It is also possible to change the electrical p...
