Abstract

The invention discloses a transformer substation remote signal resetting device and method. The device comprises a box body, a resetting receiver, and an electromagnetic relay, the outer wall of the electromagnetic relay is electrically connected with the outer wall of the resetting receiver through a power line, and the outer wall of the electromagnetic relay is electrically connected with an indication lamp through the power line. The input end of the electromagnetic relay is electrically connected with a first connector through an arranged power line, the output end of the electromagnetic relay is electrically connected with a second connector through an arranged power line, and an arranged indication lamp is used for detecting whether the electromagnetic relay needs to be reset or not. A worker observes the indication lamp of the resetting device at the regulation and control center through the robot and the video monitoring system, and when the indication lamp is turned off, the resetting receiver is connected with the regulation and control center through a cable, so that the worker can remotely control the resetting receiver to reset the electromagnetic relay, and the device can work normally; therefore, the effects of remote control and automatic reset are achieved.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a remote signal reset device and method for a substation. Background technique [0002] In order to reset the abnormal signal of the protection device at the first time, it is necessary for the operation and maintenance personnel to drive to the site for manual reset at the first time, so as to ensure the safe and stable operation of the protection secondary equipment. But now most substations of 500kV and below in our province are managed by unattended operation and maintenance teams. The operation and maintenance personnel need to go to the site to perform manual reset. Due to the different voltage levels, the number of stations under the jurisdiction of each operation and maintenance team is also different. Under the influence of road conditions, weather and other factors, the time it takes for the operation and maintenance personnel to travel from...
