Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
See Fig. 1 and Fig. 2, a kind of intelligent switch controller with quick outlet loop of the present invention comprises master cpu module, mother matrix connector and exports module fast, and supporting PC holds software, can regulate the action parameter of intelligent switch controller, as the time, phase place etc.
The divide-shut brake instruction that master cpu module sends, is also sent by different passages via microcontroller and FPGA two chip process simultaneously.
Quick outlet loop comprises relay tripping operation outlet loop and IGBT tripping operation outlet loop, and relay tripping operation outlet loop and IGBT trip outlet loop respectively by CPLD chip and difference chip drives.Quick outlet loop is used for substituting traditional relay circuit, and the time fast and accurately carries out breaker control.
The microcontroller of master cpu module and the CPLD chip links of quick outlet loop place module.Content of Communication is therebetween the message after coding.
The fpga chip of master cpu module and the difference of quick outlet loop place module turn single-ended chip links.Content of Communication is therebetween differential level signal.
Master cpu module is by the CPLD chip on message driving outlet loop, and then it is open to control exit relay, is equivalent to outlet and starts open; Meanwhile, master cpu module, by the punctual opening operation of differential conductor direct-connected control igbt chip, finally completes the quick and precisely action of whole outlet loop.Compared with traditional CPU control relay outlet mode, avoid uncertain link, very accurate on the time.
Relay tripping operation outlet loop feature is that withstand voltage is high, but operate time, uncertainty was high.The IGBT outlet loop that trips is characterised in that operate time accuracy is high.Both combine, the existing very reliable withstand voltage performance of bulk loop, and operate time is determined again completely, are applicable to the demand of the accurate zero crossing operating breaker of electric power system completely.
