Description
Technical field
The present invention relates to electrical equipment, particularly to the UPS online Hot Spare switching realizing individually power supply, have a power failure completely
Device and changing method.
Background technology
The online Hot Spare of UPS is to be exported the backup as the input of another UPS static by-pass by the inversion of a UPS, it may be assumed that
If main UPS fault, load is forwarded on the inverter output loop of standby host UPS by static switch, not only will not interruption of power supply,
And ensure that UPS output supply voltage is inverter output voltage.Therefore, this configuration can be effectively improved UPS for electric loading
The stability of power supply and reliability.Apply this configuration, if main UPS or standby host UPS breaks down when need to keep in repair, it is impossible to
It is switched to another normal operation UPS and is individually for load supplying.Owing to there is the company of " Hot Spare " form between two UPS
Connect, during handling failure UPS, the UPS of normal work may be had influence on, by the power supply of impact load time serious.Use this
The load of configuration is generally important load, possibly cannot have a power failure, when overhauling UPS, can only switch to maintenance bypass,
During this, load supplying is civil power, due to spread of voltage, load power source scaling loss grade may be caused to make trouble former.Due to UPS
Maintenance bypass can only be switched to cannot realize having a power failure completely, there is the problem that UPS cannot be realized complete interruption maintenance, as needed
Maintenance part upkeep operation completely charged must carry out, even needs to stop load and carry out.
Summary of the invention
The technical problem to be solved is to provide the UPS online Hot Spare switching dress realizing individually power supply, having a power failure completely
Put.Overcome the drawback that an independent UPS cannot be load supplying, maintenance risk is big that UPS online Hot Spare technology exists,
Promote stability and reliability that online Hot Spare technology is powered further.
