Description
Technical field
The utility model relates to intelligent power system control technology field, especially a kind of permanent magnetic vacuum breaker intelligent controller.
Background technology
The operation of present common permanent magnetic vacuum breaker control generally adopt detect by position switch close, the operating state of separating brake realizes control to coil drive current with this, its weak point is that position switch belongs to mechanical device, wear and tear for a long time or use under adverse circumstances and easily break down, make reliability decrease, the mechanical switch control precision is poor simultaneously.If position switch breaks down, controller can not in time detect operating mechanism put in place information and cut-off current immediately, and the danger that burns out coil and drive circuit is just arranged.
The utility model content
The purpose of this utility model is the deficiency on the traditional permanent magnetic vacuum breaker working method of improvement; adopt the high-speed figure central processing unit to carry out calculation process; insulated gate bipolar transistor IGBT is controlled the actuator's action of opening circuit; and RS485 interface and host computer carry out real-time communication; the Real Time Monitoring data; in time processing response, consist of Intellectualized monitoring, protection, information processing in the control unit of one.
for achieving the above object, design a kind of permanent magnetic vacuum breaker intelligent controller, it comprises wide region input switch power module, photoelectric coupling isolation signals input module, the CPU processor, the IGBT drive circuit, the relay signal output module, it is characterized in that: the power input of the CPU processor that wide region input switch power supply divides two-way to connect respectively to be integrated with display circuit and the power input of IGBT drive circuit, the signal input part that is integrated with the CPU processor of display circuit connects the output of photoelectric coupling isolation signals input module, an output that is integrated with the CPU processor of display circuit connects the signal input part of IGBT drive circuit, another output that is integrated with the CPU processor of display circuit connects the input of relay signal output module.
Described CPU processor also connects the RS485 interface circuit.
Described CPU processor adopting high-speed figure central processing unit carries out calculation process, control to drive insulated gate bipolar transistor IGBT and control the actuator's action of opening circuit, and RS485 interface and host computer carries out real-time communication.
The utility model compared with prior art, adopted the high-speed figure central processing unit to carry out calculation process, insulated gate bipolar transistor IGBT is controlled the actuator's action of opening circuit, and RS485 interface, good man-machine interface, stable control performance, long service life, non-maintaining, lightweight, volume is little, safe and reliable, carry out real-time communication with host computer easily by the RS485 interface.
Description of drawings
Fig. 1 is the connection diagram of utility model
Embodiment
The utility model is further described below in conjunction with accompanying drawing
Referring to Fig. 1, wide region input switch power module is the storage capacitor charging, for the CPU processor and the IGBT drive circuit power supply that are integrated with display circuit; The input of photoelectric coupling isolation signals has a pair of crawl to start, stop input signal, with the input signal that a pair of Long-distance Control starts, stops, CPU processor Real-Time Monitoring voltage, when accessible signal input, the ready signal of CPU processor output, liquid crystal display screen shows real-time status; When the CPU processor had detected enabling signal, the conducting of IGBT drive circuit came closed actuator, disconnected actuator when stop signal is arranged, and during actuator work, the real-time current data are effectively protected by the monitoring of Gather and input CPU processor.
