HSR291 Voltage Parallel Switch Device
Application Scope
HSR291 voltage parallel switch device is applicated to two-stage bus voltage parallel in substation automation systems. The device adopting embedded structure can be installed in switchgear dispersedly, it can also be installed in cabinet in group. The prnciple, wiring and performance is good, reasonable and reliable.
Function Configuration
When the wiring mode is double bus or signal bus and TV of one bus needs repairing due to fault, TV of the other bus need to supply voltage the two bus needs, above situation calls TV parallel switch, the prerequisite of which is reliable close state of buscoupler or switch CB.
Voltage parallel switch principle:two-side disconnectors or handcart is distinguished to be working state under buscoupler or switch CB DL is in close state, turn conversion switch to parallel position, secondary parallel of two-stage bus voltage can be fulfilled.
