Description

Technical Field

[0001] This utility model relates to the field of electrical equipment, specifically a frame-type dual power supply controller. Background Technology

[0002] A frame-type dual-power controller is an automated device used to control the switching between two frame-type circuit breakers. It is commonly used in critical power supply locations where power outages are unacceptable, enabling automatic switching between two mains power sources, two generator power sources, or one mains power source and one generator power source, ensuring continuous power supply. The working principle of the frame-type dual-power controller mainly involves power detection, logic judgment, control execution, status display, and communication. The controller uses components such as voltage transformers to monitor the phase and line voltages of the two three-phase power sources in real time. It can accurately measure voltage values ​​and determine whether abnormal conditions such as overvoltage (exceeding the rated value by a certain percentage, such as 110%), undervoltage (below the rated value by a certain percentage, such as 80%), or phase loss (one phase voltage is zero) occur. It also monitors the frequency of the two power sources to ensure that the power frequency is within the normal range. Generally, the mains frequency in my country is 50Hz. When the frequency deviation exceeds the allowable range, it may affect the normal operation of the equipment, and the controller will consider it an abnormality. Some controllers can also detect parameters such as three-phase current and power. By collecting current signals through current transformers and calculating parameters such as power, a comprehensive understanding of the power supply status can be obtained.

[0003] The control panel of a frame-type dual power controller has many buttons, including closing, opening, and other functions. To integrate multiple functions within the limited space of the control panel, the buttons are usually designed to be compact, with small spacing between adjacent buttons. In the power distribution room, control cabinet, and other places where frame-type dual power controllers are installed, the space is often relatively small. When operators are performing operations or maintenance, their bodies or tools may accidentally touch the buttons on the control panel, resulting in unintended operations. For example, accidentally triggering the opening or closing buttons may cause the circuit breaker, which is working normally, to unexpectedly open or unnecessarily close, causing power supply system failures and chaos.
