Description

technical field

[0001] The invention relates to a remote control device and method for an operating handle of a switchgear protection measurement and control device, and belongs to the technical field of power supply maintenance. Background technique

[0002] In existing substations, the protection, measurement and control devices of the switchgear are arranged in the mechanical room together with the switchgear. When it is necessary to open and close the switch, "remote operation" is the first choice, that is, through the monitoring system in the station. , operate the equipment in the mechanical room on the background machine in the main control room. The advantage of this method of operation is that you don’t have to go to the site to touch the specific equipment, which greatly reduces the risk, but it needs a complete automation system to support it. It cannot be used temporarily, and it is necessary to operate the handcart switch. There is another corresponding method c...
