Embodiment Construction

[0020] In order to provide a solution that does not rely on the original remote signaling communication channel and utilizes two substations to realize remote signaling mutual transmission, the preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0021] refer to figure 2 As shown, an unattended station disconnected remote signal remote transmission device includes: a micro-processing module MCU1, a relay 2, a power supply module 3, and an optical fiber converter 4; MCU1 is electrically connected to the input point of the remote signal source; 2 electrical connection, the relay 2 is connected in series to the remote signaling circuit to control the on-off of the remote signaling circuit, the MCU1 is connected to the optical fiber converter 4, and the input and output interfaces of the optical fiber converter 4 are disconnected from another unattended station through the optical fiber. The input and output inter...

Abstract

The invention discloses an unattended station loss-of-communication remote signaling remote transmission device, which is used for solving problems that a remote signaling communication channel in theprior art is complex in transmission structure, and communication interruption can be caused when any one of nodes goes wrong. An MCU is electrically connected with a remote signaling source input contact; the MCU and is electrically connected with a relay, the relay is connected in series into a remote signaling loop for controlling on and off of the remote signaling loop; and the MCU is connected with an optical fiber converter, an input / output interface of the optical fiber converter is electrically connected with the input / output interface of the optical fiber converter of another unattended station loss-of-communication remote signaling remote transmission device through an optical fiber, and a power supply module is connected with the MCU, the relay and the optical fiber converter.The device has advantages that a problem that remote signaling cannot be uploaded after communication of a transformer substation is interrupted is solved, a chronic problem that signals are mistakenly sent in a telecontrol mode is solved, reliability of a power grid monitoring system is improved, and uploading of ''direct-current power source disappearing'' signals can be achieved.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a remote signaling and remote transmission device for unattended stations. Background technique [0002] Substation communication interruption has always been a problem in the power grid monitoring system, especially for unattended substations. After the communication of the whole station is interrupted, the substation loses monitoring and is in a "disconnected" state, and the remote signal cannot be uploaded. Bring inconvenience, even cause accident expansion, hidden danger is great. [0003] refer to figure 1 As shown, the existing substation remote signaling communication channel contains many communication devices, any device failure may cause communication interruption, and the risk of communication interruption is high. The following reasons will cause the communication interruption of the substation: [0004] (1) Loss of DC power leads to communication interrupt...
