Visual alternating current distribution board with interlock protection function

Abstract

The invention provides a visual alternating current distribution board with interlock protection function. The distribution board comprises a bus bar which is connected with an alternating current power supply and is provided with a circuit breaker and a contactor. The distribution board is characterized by also comprising a detection and acquisition unit, an interlock control unit and a comprehensive display unit, wherein the detection and acquisition unit is connected with the alternating current power supply and is used for acquiring the voltage value, the current value, the power factor and the power of the alternating current power supply; the interlock control unit is connected with the circuit breaker and the contactor and is used for acquiring state signals of the circuit breaker and the contactor, processing the state signals, outputting control signals and feeding the control signals back to the circuit breaker and the contactor, and the comprehensive display unit is connected with the detection and acquisition unit and the interlock control unit and is used for receiving signals and displaying states on different screens. Due to the adoption of visualization function and interlock protection function, real-time running of the alternating current power supply and a power supply network is monitored, and all switch protection elements in the alternating current distribution board are controlled and protected.

Description

technical field [0001] The invention relates to an AC power supply and distribution network. Background technique [0002] The AC distribution board is the most important power distribution equipment in land and marine power grids. It is responsible for the power supply and distribution of power equipment, and has comprehensive functions such as power grid management, protection, and operation. With the development of modern technology, on the one hand, the protection function of power distribution equipment for the power grid is becoming more and more perfect; on the other hand, users have higher and higher requirements for the safety and humanization of the comprehensive operation of the power distribution board on the entire ship's power grid. . [0003] With the increase of the complexity of the AC power grid, the safety, reliability and rationality of the operation of the AC distribution board are becoming more and more important. On the one hand, if operators lack a ...

AI Technical Summary

Problems solved by technology

On the one hand, if operators lack real-time knowledge of the operating status of the entire network, they often need to check and confirm the power supply and distribution status of the grid before operating the AC distribution board, which is inefficient; on the other hand, operators are operating Always keep a clear mind, operate properly, and strictly follow the operating procedures, otherwise it is very easy to misoperate, which may cause power failure accidents and bring adverse effects on the AC power grid and electrical equipment
