Transformer substation intelligent protection warning method based on Internet of Things

Abstract

The invention provides a transformer substation intelligent protection warning method based on the Internet of Things, and belongs to the technical field of power protection methods. The method comprises the following steps: setting a protection warning device in a transformer substation, and enabling the protection warning device to be in signal connection with a transformer substation control workstation; the transformer substation control workstation displays the operation state of the protection warning device and transmits a control instruction to the protection warning device through a signal transmitting control mainboard according to transformer substation remote signaling information; after receiving the control instruction, a motor controller of the protection warning device controls an electric push rod to act; and meanwhile, an angle sensor arranged on the electric push rod sends a real-time inclination angle signal of the electric push rod to a motor controller, and afterthe motor controller receives the angle signal, the action speed and the stroke distance of the electric push rod are adjusted till the requirements of the control instruction are met. According to the application of the invention, the time for arranging and dismounting existing barrier and / or warning sign can be greatly reduced, and the operation safety and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of electric power protection methods, and in particular relates to an intelligent protection warning method for substations based on the Internet of Things. Background technique [0002] When working in a substation, the scheduled time is usually the start time of the switching operation. After the switching operation is completed, it takes a certain amount of time to set up fences and sign boards. The larger the work site, the more complicated the setting of on-site measures, which affects the maintenance work time. Similarly, after the maintenance work is over, it is necessary to dismantle the fence and signboard, which takes a lot of time and affects the power transmission time. [0003] The patent document with publication (announcement) number CN202009267U discloses an integrated monitoring and analysis system for intelligent substation equipment status, including multiple substation monitoring systems...
