Eddy current actuated three-phase three-mechanism intelligent vacuum circuit breaker based on internet of things technology

Abstract

The invention provides an eddy current actuated three-phase three-mechanism intelligent vacuum circuit breaker based on an internet of things technology. The three eddy current actuating mechanisms ofthree poles are arranged in a line on a frame, a main conductive loop of the circuit breaker and an operating mechanism are longitudinally distributed front and back and are linked through a transmission crank arm, in each pole, a fixed package pole column integrated with a wireless temperature measuring module, a Rogowski coil and a vacuum arc extinguish chamber is arranged, and a manual lever capable of manual test and switching-on and switching-off in emergency is arranged a charging unit for charging a super capacitor which discharges a switching-on coil through an IGBT module is arranged, an indicating piece for displaying the working state of the circuit breaker is arranged, a counter for recording the action times of the circuit breaker is arranged, and an auxiliary switch for linkage and switching of the working states and a self-reset displacement sensor are arranged. The circuit breaker is simple in structure, high in action speed and convenient to operate, information exchange and communication are performed through monitoring and control of the wireless and cloud server and the user terminal, and intelligent identification, positioning, tracking, monitoring and management of the circuit breaker are improved.

Description

technical field [0001] The invention relates to the technical field of intelligent vacuum circuit breakers based on Internet of Things technology, in particular to an eddy current actuated three-phase three-mechanism intelligent vacuum circuit breaker based on Internet of Things technology. Background technique [0002] With the development of the Internet of Things technology and the steady advancement of the national smart grid construction scale, it is the user's final choice to control more convenient, reliable, and smarter electrical equipment; at the same time, with the increase of sensitive loads, it is required to be an important control system for the power primary system. And protection equipment--vacuum circuit breaker, which allows the management to understand the operating conditions of the equipment anytime and anywhere, and requires them to realize synchronous intelligent operation, etc. The grid dispatching automation system is moving towards digitization, int...

Problems solved by technology

[0003] At present, the following are still widely used in the power system: 1. Circuit breakers with relatively complex operating mechanisms; 2. The operation functions of phase selection closing and synchronous breaking cannot be realized; 3. The action time cannot be guaranteed to be short enough; 4. Needs Separately equipped with a microcomputer protection device to monitor and control its operating conditions; 5. The degree of integration is not high; 6. The function is single; 7. It is not possible to check whether the mechanical characteristics of the circuit breaker are unfavorable to safe operation during operation. Changes, whether the heating condition between the moving and static contacts is kept within the allowable temperature rise range, whether a short-circuit fault occurs in the power supply feeder circuit, and whether the protection action can be taken in the shortest time, so as to quickly cut off the fault current and protect the stable operation of the power grid system , and at the same time, can the above information be passed on to the management personnel for processing and timely mastery, etc.
