Switch handle protection and measurement device operating handle remote control device and method

Abstract

The invention relates to a switch handle protection and measurement device operating handle remote control device and method, belonging to the technical field of power supply maintenance. The technical scheme is that the front center of a shell is provided with a switching switch handle (2) which is matched with a switch-on and switch-off switching shaft or handle on a switch cabinet, the switching switch handle (2) is connected to an output shaft of a stepping motor (6), the stepping motor (6), a PLC (7) and a motor controller (8) are arranged in the shell, the PLC (7) is connected to the stepping motor (6) through the motor controller (8), a wireless module (9) and a power supply are connected to the PLC (7), a magnetic part is formed by multiple strong electromagnets (3) and is arranged around the switching switch handle (2), and the multiple strong electromagnets (3) are connected to the power supply through a manual switch. The switch handle protection and measurement device operating handle remote control device and method have the advantages that the staff can operate the operating handle on the switch cabinet when the staff maintains a certain distance from the switch cabinet, the operation is accurate, the observation is convenient, and the personal safety of the staff is not threatened.

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...

[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 called "on-site operation", that is, to realize the operation of the switch by manually operating the opening and closing handle on the switch cabinet. The method goes through few links and is easy to succeed, but it requires staff to go to the equipment to implement it. Once the switchgear fails, the personal safety of the staff will be threatened
