Problems solved by technology

[0004] The existence of induced voltage and its high value greatly affect the authenticity of the data received from the background
Moreover, the peak induced voltage can easily break down and burn the serial and parallel ports on the plug-in of the communication device, greatly affecting the reliability of power supply and causing huge costs for plug-in replacement

Embodiment Construction

[0014] like figure 1 As shown, the present invention is a communication device of an integrated self-system based on OPT-103, which is mainly composed of a data input part 1, a conversion part 2, a transmission part 3 and an output part 4, which changes the traditional integrated self-system communication channel A mode consisting of a Cat5e or RS-485 cable. The data input part 1 receives the communication data of the protection device (as shown in the figure, the data collected for each interval of the 10KV and 35kV high voltage chambers), and then the conversion part 2 (this embodiment uses OPT-103) on the spot Converted to optical signals, the transmission medium of the transmission part 3 adopts optical fiber, and the data is sent to the conversion device of the output part 4 through the optical fiber transmission part 3, and the conversion device of the output part 4 converts the optical signal into an electrical signal for output. In this way, it can avoid the influence...

Abstract

The invention discloses an optical fiber communication channel of an integrated automatic system. The channel comprises an input part, a conversion part, a transmission part and an output part of data, wherein the input part is connected with the conversion part; the conversion part is connected with the output part through the transmission part; and an optical fiber is used as a transmission medium of the transmission part. In the channel, communication data output by a protective device is locally converted into an optical signal by a data conversion part OPT-103, and data is transmitted to a conversion device of the output part by an optical fiber transmission part and converted into an electric signal for outputting. In the optical fiber communication channel, a super type-V cable or an RS-485 cable can be prevented from being influenced by strong electromagnetic induction voltage in a cable channel, the data is real and a communication plug-in unit is prevented from being broken down or burnt down by induction voltage.

Description

technical field [0001] The invention relates to an optical fiber communication device, in particular to an optical fiber communication channel for an integrated automation system. Background technique [0002] The communication devices of power substations are generally located in the main control room or a separate communication room, while the 10KV and 35KV high-voltage rooms are generally located far away, so the communication between the 10KV and 35KV protection devices and the communication devices requires a long communication medium, and this The medium should be laid along the cable trench full of primary high-voltage cables, secondary AC and DC power supplies, and control cables. The traditional integrated system communication channel is a mode composed of a super five line, RS-485 or RS-232 cable, so that, according to the law of electromagnetic induction, the cable will be in this cable trench with a strong magnetic field density. The magnetic field lines are cut...
