Description
Technical field
The utility model relates to a kind of three-way power switching device shifter.
Background technology
In order to guarantee power supply reliability, the two-way Power supply generally all is set.Double loop power supply is set and powers when ， mono-road power supply breaks down afterwards, can enable another road Power supply, effectively guaranteed the normal operation of equipment, contribute to the relevant device non-stop run.The power supply of use double loop power supply, just need supporting dual power switching device, to realize timely, the reliable switching of power supply.
Current dual power switching device, comprise manual type and self-action, and the manual type dual power switching device is simple in structure, operates simple and easyly, and cost is low, and shortcoming is to need manual operation, has certain danger and hysteresis quality.Self-action dual power switching device structure is more complicated, and cost is higher, but can play the effect of automatic switchover when breaking down.No matter the dual power switching device of which kind of mode, although can realize the handoff functionality of power supply, but all can only be switched according to the fault of two-way power supply, that is to say when a road power supply breaks down, do not switched when another road power supply breaks down, and, when the two-way power supply does not all break down, can not carry out according to the power supply quality of power supply the selectivity switching, and the two-way power supply is while all breaking down, just do not had the power supply that can select to be switched, choice is less.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, can be according to the three-way power switching device shifter that the power supply quality of power supply is switched, the power supply range of choice is large, power supply reliability is high.
For reaching above purpose, the technical scheme that the utility model adopts is: comprise the first branch road and the second branch road that are electrically connected to the two-way independent current source, also comprise the 3rd branch road be electrically connected to generator, the middle part of described three branch roads is equipped with the contactor by the controller control action, on the input section of described three branch roads, the measurement module be electrically connected to the controller input is installed, the deferent segment of described three branch roads is connected in parallel by copper bar.
This three-way power switching device shifter is that switching construction is realized being switched according to the power supply quality of power supply, the power supply range of choice is large, power supply reliability is high by detecting.
Detecting switching construction mainly comprises the contactor that is arranged on these three branch roads middle parts of the first branch road, the second branch road and the 3rd branch road, is arranged on three measurement modules on branch roads input section, and the controller be electrically connected to measurement module and contactor, these three branch road deferent segments are connected in parallel by copper bar, have formed three tunnels and have inputted the overall structure that export on a road.Wherein, the Main Function of measurement module, be that the information such as voltage to three power supply branch roads, electric current detect in real time, and be real-time transmitted to controller.After controller receives the detection information of measurement module, can be analyzed the electric power thus supplied of three power branch, thereby get rid of, the power branch of power supply trouble occur and select the power supply branch road that power supply quality is higher.After analysis is obtained a result, controller will carry out the switching of three branch roads by control contactor, thus the power branch that the choice for use power supply is the most stable, power quality is the highest power supply.Because this three-way power switching device shifter is to automatically switch under the control of controller, so switch speed is fast, without any manual intervention.
As improvement, on the input section of described three branch roads, the input circuit breaker is installed.
Input circuit breaker by operation, can control the break-make of three branch road input sections, when breaking down, can, by manual intervention mode force disconnect power circuit, guarantee power supply reliability like this.
As improvement, the output circuit breaker is installed on the deferent segment of described three branch roads.
Export circuit breaker by operation, can control the break-make of three branch road deferent segments, when breaking down, can, by manual intervention mode force disconnect power circuit, guarantee power supply reliability like this.
As further improvement, described controller drives the contactor action by driver module.
Drive contactor work by special-purpose driver module, can strengthen driving power, guaranteed the reliability of contactor action.
In sum, adopt the three-way power switching device shifter of said structure, rational in infrastructure, can be switched according to the power supply quality of power supply, the power supply range of choice is large, power supply reliability is high.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model propradation.
Embodiment
As shown in the figure, this three-way power switching device shifter comprise the first branch road 1 and the second branch road 2, the first branch roads 1 and the second branch road 2 respectively the power supply separate with two-way be electrically connected to, such the first branch road 1 and the second branch road 2 are exactly the separate power circuit of two-way.This three-way power switching device shifter also comprises be electrically connected corresponding with generator output end of the 3rd branch road 3, the three branch roads 3.Like this, the first branch road 1, the second branch road 2 and the 3rd branch road 3 have just formed three power branch of this three-way power switching device shifter, and these three branch road deferent segments are connected in parallel by copper bar 6, have formed three tunnels and have inputted the overall structure that export on a road.
