Abstract

The invention discloses a substation real-time monitoring device with ground wire faulty operation prevention locking, relates to the substation real-time monitoring device, and aims to solve the problems that real-time monitoring of a ground wire of a working site cannot be performed and monitoring cannot be performed for preventing faulty operation of the substation operation personnel in the conventional substation ground wire monitoring device. A data signal output and input end of a ground signal acquisition component is connected with a data signal input and output end of a signal space and control component; the data signal output and input end of the signal space and control component is connected with the data signal input and output end of a substation end control component; a control signal output end of the signal space and control component is connected with a control signal input end of external primary equipment; and the device can realize the functions that the substation operation personnel can monitor the ground wire of the working site in real time and avoid the faulty operation for logic locking. The device can be widely applied to monitoring the connection state of the ground wire of a high-voltage line of various voltage levels.

Description

technical field [0001] The invention relates to a real-time monitoring device for a substation. Background technique [0002] With the gradual deepening of power grid renewal and transformation, substations have begun to apply a large number of new power on-line monitoring and control systems, and gradually eliminate old equipment such as the original control panel, instrument panel, and operation simulation panel. Organically integrate the substation monitoring system and the grounding wire monitoring device, give full play to their respective advantages, and develop a new type of grounding wire intelligent monitoring system to meet the urgent needs of safe production for intelligent power grids. [0003] The existing substation grounding wire monitoring device can only monitor the closing and opening status of the grounding switch, but the real-time monitoring of the grounding wire at the work site and the prevention of misoperation by the substation operator from closing ...
