An intelligent isolating switch control device and its control method

Abstract

The invention discloses an intelligent isolating switch control device, which comprises an isolating spindle for driving an isolating switch to act, a driving assembly, a transmission assembly and a controller. The driving assembly is rotationally connected with the isolating spindle through the transmission assembly. The driving assembly comprises a moving rod and a permanent magnet coil for driving the moving rod to move. The moving rod is provided with an iron core which is located on the inner circumference of the permanent magnet coil. A permanent magnet is arranged in the permanent magnet coil. The controller is used to apply a negative or positive voltage to the permanent magnet coil, so as to drive the moving rod to move. The moving rod drives the isolating spindle to rotate through the transmission assembly, so as to realize the closing or opening of the isolating switch. Because the permanent magnet coil instead of a spring is used as a power source, the output force characteristic curve is better matched with the action stroke of the switch, and the control accuracy for the isolating switch is improved. Compared with the spring, the structure of the whole device is simplified, the failure rate is reduced, and the service life is increased. A control method of the device is also provided.

Description

technical field [0001] The invention relates to the technical field of power grid control, in particular to an intelligent isolating switch control device and a control method thereof. Background technique [0002] With the scale of urban construction and the rapid development of the economy, higher requirements are put forward for the reliability, environmental protection, and intelligence of the power distribution network. The power system also has high reliability requirements in terms of mechanical performance, stability, and secondary control systems. Most of the existing isolating switch control devices use springs as power sources, such as quick opening and closing through manual spring energy storage and release, or use motors for spring energy storage. However, since the spring is a purely mechanical part, whether it is Both electric and manual spring energy storage isolation operating devices have the problem that the output force characteristic curve does not mat...

Problems solved by technology

Most of the existing isolating switch control devices use springs as power sources, such as quick opening and closing through manual spring energy storage and release, or use motors for spring energy storage. However, since the spring is a purely mechanical part, whether it is Both electric and manual spring energy storage isolation actuators have the problem that the output force characteristic curve does not match the action stroke of the switch, which makes the control accuracy of the isolation switch insufficient.
