Embodiment 1

[0023] In a typical embodiment of the present invention, such as figure 1 As shown, the present invention is a comprehensive monitoring and management system for the environment of the control cabinet based on intelligent perception and coordinated control, including a main control terminal in the cabinet, a temperature and humidity sensor, a dehumidifier, a heater, an exhaust fan, a communication module and a system platform , There are multiple control cabinets, and each control cabinet is equipped with a temperature and humidity sensor, a dehumidifier, a heater, and an exhaust fan. The temperature and humidity sensor is used to collect the temperature and humidity inside and outside the control cabinet and transmit it to the system platform.

[0024] The gamb it software is used to establish the physical model of the control cabinet, and the mesh is divided, and then poured into the fluent software for fluid simulation. The turbulence model adopts the common model of enginee...

Embodiment 2

[0041] In a typical embodiment of the present invention, such as figure 1 As shown, a method for comprehensive monitoring and treatment of the environment of the control cabinet of the present invention uses a comprehensive monitoring and treatment system for the environment of the control cabinet as described in Embodiment 1 to operate, and uses the main control terminal, dehumidifier, and exhaust fan in the cabinet , The temperature and humidity sensor controls the temperature in the control cabinet, develops the environment monitoring and coordination control system platform in the cabinet, and monitors the terminal operation of each dehumidification device in real time. The system platform sends the control cabinet temperature and humidity control command to the terminal of the dehumidification device, and the terminal feeds back the environmental monitoring information after the control command is run. The new control model training sample corrects the model between the f...

Abstract

The invention discloses a control cubicle environment comprehensive monitoring and treatment method and system, which belong to the field of power systems, optimizes and integrates operation and inspection resources by means of Internet of Things multi-sensor intelligent sensing, artificial intelligence control and big data analysis technology means, realizes automatic acquisition, real-time uploading, visualization and remote sensing of environment information in a control cubicle, and realizes intelligent adjustment of the environment of the control cubicle. The system platform monitors thetemperature and humidity in the cubicle in real time through a temperature and humidity sensor arranged in the control cubicle. The system platform forms a control model training sample through temperature and humidity monitoring information in a plurality of substations, corrects a model between the characteristic quantity and the condensation defect of the control cubicle, and forms an information closed loop, thereby achieving the advanced adjustment and comprehensive control of the environment.

Description

technical field [0001] The invention belongs to the field of electric power systems, and in particular relates to a method and system for comprehensive monitoring and treatment of the environment of a control cabinet. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] With the development of electrical equipment manufacturing level, HSBC cabinets have been widely used in power systems, and the application prospects are good. As the insulation distance shrinks again and again, the insulation level of the cabinet with condensation is severely tested. Condensation is a phenomenon in which water vapor condenses on relatively low-temperature objects when the air is saturated. The water droplets cover the surface of the insulating material, generating partial discharge and damaging the insulation. Long-term operation will cause insulation breakdown failure...
