Brief description
Fig. 1 is the basic structure schematic diagram of three-way power CB level automatic transfer switching equipment of the present invention.
Specific embodiment
Referring to Fig. 1, three-way power CB level automatic transfer switching equipment of the present invention, it is applied to three power supplys and automatically switch
In system；Including base plate 1, three choppers 2 and three motor-operating mechanisms 3 with energy pre-storage and intelligence are controlled
Device processed (not shown out), three choppers are moulded case circuit breaker, and it is mounted side by side on base plate,
Undertake connection and the disjunction work of three-way power respectively；Three motor-operating mechanisms with energy pre-storage are separately mounted to three
On platform chopper, drive connection and the disjunction of three choppers respectively；Three motor-operating mechanisms with energy pre-storage are pre-
First deposit has combined floodgate energy, when needing combined floodgate chopper, making electromagnet action, and discharge combined floodgate energy, open circuit
Device instantaneously closes a floodgate.Intelligent controller is arranged on base plate or is independently arranged, and controls three road electricity by motor-operating mechanism
Conversion between source.This intelligent controller detects magnitude of voltage, frequency values and the phase angle of three-way power, examines when real-time
Measure magnitude of voltage, frequency values and the phase angle of a certain road power supply and when setting value has deviation, start corresponding electric operating
Mechanism realizes the conversion between three-way power.
Three choppers in the present invention respectively come with under-voltage release, for electromechanical interlock, by Based Intelligent Control
Device, after a road power supply switching up, the power supply time delay of another road disconnects, and meets uninterrupted, no transition power reguirements,
Then interlocked with under-voltage release.
Before a road power supply switching, using phase angle phase shift technology, substantially it is consistent at the phase angle of two road power supplys
In the case of carry out power supply and uninterruptedly switch.
