1. What is analog screen. Analog panel is a kind of power equipment used in distribution room, substation and substation. It is one of the necessary devices. Its main function is to prevent power misoperation. There are electrical main wiring diagram, handle (commonly known as button switch) that can perform pre operation and indicator light that can indicate the status of equipment on the simulation screen.
2. Importance of analog screen. Electrical misoperation is a frequent accident threatening the safe operation of the power grid. The occurrence of the accident can cause large-scale power failure, electrical equipment destruction, power grid vibration and collapse, and even cause serious personal injury and death accidents. Preventing misoperation is an eternal topic of electrical operation. Using the analog panel system in the operation process is one of the powerful measures to prevent electrical misoperation.
3. Composition of analog screen. Analog screen is composed of analog screen frame, mosaic block, computer engraving primary system diagram, knife switch button, switch button, grounding device, plane light, power supply, etc. According to the user's requirements, it can be additionally equipped with: safety days, station establishment date, electronic clock, cycle table, ground wire error alarm device, etc. for users with strict requirements, it can also install a microcomputer locking device or select a simulation screen with logic preview and alarm functions, etc.
As an important analog display equipment in the industrial field, analog panel has been widely used in the system dispatching and monitoring center of public utilities and related fields. It can display the working parameters and running status of the field equipment in real time, and reflect the running status of the system equipment to the dispatcher in a timely, real and comprehensive way. In some systems with relatively frequent equipment changes, due to the limitations of the computer display itself, it is difficult to achieve the expected effect if it is used to simulate the display or to monitor the operation status of multiple pictures and parameters, which makes it difficult for the operators to master the situation of the controlled system.
Simulation panel was introduced into China in the early 1990s, and quickly became an important part of large-scale enterprise dispatching monitoring system. It plays an irreplaceable role in the central dispatching monitoring system of power, coal, water conservancy, environmental protection, highway, railway, aviation, chemical industry and other industries. The physical structure of the simulation screen is constantly updated. The screen material is from the initial metal material to the current flame-retardant engineering plastics, and the screen structure is also from the initial integrated type to the current block type. For more than 20 years, Shenle company has been committed to the research and development of the mosaic simulation screen field, and constantly adapt to the environment and the needs of various times.
