Switchgear handcart electric remote operation device and method

Abstract

The invention relates to a switchgear handcart electric remote operation device and method and belongs to the technical field of electrical equipment. The technical scheme is characterized in that the device comprises a power device (1), a local control panel (6), a local measurement and control device (12) and a remote monitoring host (13). The remote monitoring host (13), the local measurement and control device (12) and the local control panel (6) are connected in sequence. The power device (1) comprises a low-speed motor (2), a small gear (3), a large gear (4) and a transmission connection rod (5). The low-speed motor (2) is connected with the small gear (3); the small gear (3) and the large gear (4) are engaged mutually; the large gear (4) is mutually connected with the transmission connection rod (5); the local control panel (6) is connected with the low-speed motor (2); and the transmission connection rod is connected with a roll-in-roll-out bearing of a handcart switch. The device can achieve a purpose of remote roll-in-roll-out control of the handcart switch, thereby reducing operator on-site operation frequency and improving operation efficiency.

Description

technical field [0001] The invention relates to an electric remote operation device and method for a handcart of a switch cabinet, belonging to the technical field of electric power equipment. Background technique [0002] At present, in the power system, especially the operation of 10kV or 35kV switchgear in the substation, the switch is opened remotely, and then the operator operates the handcart switch on the spot, pulls the handcart switch to the standby position, and then the line maintenance personnel can work. With the increase of substations, intelligent substations and unattended substations, personnel drive to the site to operate the trolley, resulting in a lot of waste of manpower and material resources, and prolonging the time for power outage maintenance. Contents of the invention [0003] The object of the present invention is to provide an electric remote operation device and method for a handcart of a switchgear. By adopting an on-site measurement and contr...
