Principle: electric elements are all contained on machine core trolley, when movement breaks down, can pull out dolly outside case, to overhaul and change standby movement; The turnover campaign of machine core trolley adopts rack and pinion engagement manual actuation mode, and dolly pulls out, advance and operate steadily, fast, reliably, and machine core trolley Auxiliary Track is installed and adopted accordion structure can save space reduced volume; Microcomputerized overall protective device, has the defencive functions such as overload, short circuit, electric leakage, cable insulation supervision, has electric current, function displaying voltage, has fault category textual representation function.
Permanent magnetic actuator vacuum circuit breaker has the advantages such as high-performance, highly reliable, non-maintaining, connecting-disconnecting function strong, divide-shut brake speed is fast, and realizes overvoltage protection by distribution type silicon rubber Zinc-oxide piezoresistor, has eliminated the hidden peril of explosion of common piezo-resistance.
Lower chamber is provided with a zero-sequence transformer and control line outlet nozzle, and user can draw control line and monitoring communication realizes the interlocking that He Tai and platform are controlled in a distant place.
Chamber door is eyelet bolt presser type shutter structure, and arrange reliable mechanical locking device (in running, can not open chamber door, only have breaker open operation, isolation latch in separation point position, remove casing with locking, door closure can be opened).Liquid crystal display window, state display window to change mouth and illumination are set on chamber door, seven buttons start, stop, leaking electricity, be shifted, confirm, reset.
On housing ante-chamber left side plate, respectively have an observation window, can see isolation latch deciliter situation, right side is provided with " dividing ", " closing " lock of isolation latch, manual-operating mechanism, circuit breaker manual brake separating operating mechanism.
Beneficial effect: volume of the present invention is little, lightweight, compact conformation, rationally, operation is directly perceived, flame proof chamber door adopts quick operating valve pattern, the inner handcart-type that adopts, all primary element permanent magnetic actuator vacuum circuit breakers, (electric current, voltage) instrument transformer and high-tension fuse and secondary component low-tension fuse etc. are all contained on handcart, and ,Wei simple to operate procuratorial organ just; There is advanced, perfect microcomputerized overall protection system; controlled circuit is had to short circuit, overcurrent, electric leakage, insulation monitoring, overvoltage, under-voltage and phase failure protection function, combine the self-checking function of possessing fault own, full Chinese display; simple, intuitive, and there is fault long-term memory function.And needn't open casing gate and can carry out adjusting of Protection parameters, be convenient to operation and improved the reliability of bulk supply.
