Technical field
The utility model relates to electrical equipment, the online Hot Spare switching device shifter of UPS particularly realize power supply separately, having a power failure completely.
Background technology
The online Hot Spare of UPS exports by the inversion of a UPS backup inputted as another UPS static by-pass, that is: if main UPS fault, load forwards on the inverter output loop of standby host UPS by static switch, not only can not interruption of power supply, and ensure that UPS output supply voltage is inverter output voltage.Therefore, this configuration effectively can improve UPS and to power the stability of load power source and reliability.Apply this configuration, if main UPS or standby host UPS breaks down when need keep in repair, cannot be switched to another normal operation UPS is separately load supplying.Owing to there is the connection of " Hot Spare " form between two UPS, during handling failure UPS, the UPS of normal work may be had influence on, time serious, will the power supply of load be affected.Adopt the load of this configuration to be generally important load, possibly cannot have a power failure, when overhauling UPS, can only switch to maintenance bypass, load supplying is civil power during this period, due to spread of voltage, load power source scaling loss grade may be caused to make trouble former.Cannot realize having a power failure completely because UPS can only switch to maintenance bypass, there is the problem of complete interruption maintenance of cannot realizing UPS, must chargedly carry out as part upkeep operation need be overhauled completely, even need to stop load and carry out.
Utility model content
Technical problem to be solved in the utility model is to provide the online Hot Spare switching device shifter of UPS realizing power supply separately, have a power failure completely.Drawback, the stability that the online Hot Spare technology of further lifting is powered and reliability that the independent UPS overcoming the existence of UPS online Hot Spare technology cannot have a big risk for load supplying, maintenance.
For achieving the above object, the utility model realizes by the following technical solutions:
The online Hot Spare switching device shifter of UPS realize separately power supply, having a power failure completely, switching device shifter by connection between main frame UPS1 and standby host UPS2, comprise commutation circuit, load circuit and the outer bypass power supply system of load, main frame UPS1 and standby host UPS2 is powered by higher level's electric power system respectively, its input arranges input switch Q1 and input switch Q3 respectively, main frame UPS1 output connects load circuit, and be provided with output switch Q2, the output of standby host UPS2 is connected with the static by-pass input of main frame UPS1, and be provided with diverter switch Q4 and diverter switch Q5, between the power supply circuits that commutation circuit is connected to main frame UPS1 and load circuit, and cross with the connecting circuit of main frame UPS1 and standby host UPS2, diverter switch Q6 and diverter switch Q7 is respectively equipped with before and after joint, the outer bypass power supply system of load is connected on load circuit, and be provided with outer bypass input switch Q8.
Described higher level's electric power system and the outer bypass power supply system of load are all furnished with low-voltage distribution cabinet, and low-voltage distribution cabinet is respectively equipped with low-voltage cabinet switch.
Under described main frame UPS1 and standby host UPS2 normal operating conditions, main frame UPS1 input switch Q1, main frame UPS1 output switch Q2, standby host UPS2 input switch Q3, diverter switch Q4 and diverter switch Q5 are "on" position, and diverter switch Q6, diverter switch Q7 and outer bypass input switch Q8 are gate-dividing state.
Described main frame UPS1 and higher level's electric power system of standby host UPS2, from two different transformers, do not allow paired running.
Compared with prior art, the beneficial effects of the utility model are:
The utility model small investment, rationally switches under the stability improving UPS out-put supply and reliability prerequisite.For the power supply not affecting load equipment during UPS time-based maintenance maintenance, separate unit or the process of two UPS equipment machine halt troubles provides solution.When separate unit UPS fault or when safeguarding, load can be switched to the UPS of another normal operation, the risk reducing fault UPS maintenance or safeguard, ensure that load supplying is still inverter out-put supply during this period.When two UPS simultaneous faultss, set up outer bypass changeover function, two UPS can have been departed from from online Hot Spare configuration, realize outer bypass directly to load supplying.In addition, this switching device shifter can realize two complete interruption maintenances of UPS or the maintenance of online Hot Spare configuration.
