Detailed description of the invention
Fig. 1 to Fig. 3 below in conjunction with the accompanying drawings controls device to a kind of breaker closing of the present utility model and makees the most in detail
Describe in detail bright.
A kind of breaker closing of the present utility model controls device, refer to Fig. 1-3, including phase acquisition device 1, phase place prison
Control module 2 and chopper 3；Described phase acquisition device 1 is connected with described phase place monitoring module 2, is used for receiving the monitoring of described phase place
The reclosing command that module 2 sends, and feedback signal is to described phase place monitoring module 2；Described phase place monitoring module 2 and described open circuit
Device 3 connects, and is used for sending switching signal, makes described chopper 3 close a floodgate at set angle.So, phase place monitoring module 2 is to phase place
Harvester 1 sends reclosing command, after phase acquisition device 1 receives reclosing command, starts to detect line voltage waveform,
When voltage waveform proceeds to set angle, phase place monitoring module 2 feeding back switching signal, phase place monitoring module 2 receives combined floodgate
After signal, transmission switching signal, to chopper 3, makes chopper 3 close a floodgate in the angle set, and utilizes the one of this programme to break
Road device closing control device, it is possible to control chopper 3 and close a floodgate in optimum angle, reduce peak electricity in chopper 3 making process
