Technical field
The utility model relates to power domain, particularly voltage source switch controller electric power system in one.
Background technology
Emergency power supply is the power supply adopted in order to emergency lighting, emergency lighting and fire protection equipment etc. in current important building, can provide emergency service under emergency rating.Clear stipulaties in " design of civil buildings specification ": first order load should by two Power supplies, and when a power failure, another power supply should unlikelyly be damaged; The form of power of first order load has two tunnel high voltage sourcies and a road high voltage source and a road low-tension supply, diesel generating set and batteries; In first order load, the load of particular importance is except above-mentioned two power supplys, also must set up emergency power supply.Conventional emergency power supply has: EPS (EmergencyPowerSupply) emergency power supply, UPS (UninterruptiblePowerSupply) uninterrupted power supply, provide diesel emergency generating set for oneself, have the special feeder line independent of normal power source of automatic throw-in equipment and provide emergent gas turbine generator group for oneself.
Middle voltage source switch controller is mainly used in electric power system monitoring two-way power work situation, when conventional line under-voltage, decompression or power-off time control mains switch load circuit switched power supply to emergency power supply from conventional, control mains switch when conventional power up is normal and load circuit is switched to conventional power supply from emergency power supply, to guarantee that important load runs continuously, reliably.In existing middle voltage source switch controller electric power system, when power supply is unstable, middle voltage source switch controller cannot Timeliness coverage abnormal, if electric power output voltage is low to certain value, middle voltage source switch controller may quit work, cannot detect the two-way power supply of mains switch, record and even switch, and then the normal operation of whole electric power system can be affected.
Utility model content
The technical problems to be solved in the utility model be in middle voltage source switch controller electric power system in voltage source switch controller cannot the abnormal conditions such as Timeliness coverage supply voltage is too low, provide a kind of can the middle voltage source switch controller electric power system that exports of Real-Time Monitoring power supply.
The utility model solves above-mentioned technical problem by following technical proposals:
Voltage source switch controller electric power system in one, its feature is, comprises power module, display module, middle voltage source switch controller and transmitter; Described middle voltage source switch controller comprises the signal of telecommunication receiver module with analog interface; Described transmitter is electrically connected with the analog interface of described power module and described middle voltage source switch controller respectively; Described display module is electrically connected with described middle voltage source switch controller; Described transmitter is used for the voltage signal that described power module exports to be converted to current signal; Described display module is for showing the value of the current signal of described signal of telecommunication receiver module reception.
Preferably, described middle voltage source switch controller electric power system also comprises alarm, and described alarm is electrically connected with described middle voltage source switch controller; Described middle voltage source switch controller is also for the more described signal of telecommunication receiver module current signal received and the alarm current value preset, when described default alarm current value is greater than the current signal of described signal of telecommunication receiver module reception, described middle voltage source switch controller triggers described alarm equipment alarm.
Preferably, described power module voltage output range is 0 ~ 24 volt, changes after-current range of signal into 4 ~ 20 milliamperes through described transmitter.
Preferably, described analog interface is multiple.
Positive progressive effect of the present utility model is: compared with existing middle voltage source switch controller electric power system, the direct voltage that power module exports converted to by increasing transmitter the current signal that middle voltage source switch controller can receive, display shows the value of current signal in electric power system in real time, thus can Timeliness coverage abnormity of power supply processing.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the middle voltage source switch controller electric power system of the utility model one preferred embodiment.
Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
As shown in Figure 1, voltage source switch controller electric power system in one, comprises power module 4, display module 5, middle voltage source switch controller 1, transmitter 3 and alarm 6.Wherein middle voltage source switch controller 1 comprises the signal of telecommunication receiver module 2 with analog interface; Transmitter 3 is electrically connected with the analog interface of power module 4 and middle voltage source switch controller 1 respectively; Display module 5 and alarm 6 are electrically connected with middle voltage source switch controller 1 respectively; Transmitter 3 is converted to for the d. c. voltage signal exported by power module 4 current signal that signal of telecommunication receiver module 2 can receive, in the present embodiment, the voltage output range of power module 4 is 0 ~ 24 volt, the current signal scope exported after transmitter 3 is changed is 4 ~ 20 milliamperes, and in after voltage signal is only converted to the current signal of above-mentioned scope herein, voltage source switch controller 1 just can receive and identify.By the value of the current signal observing display on display module 5, display module 5, for showing the value of the current signal of signal of telecommunication receiver module 2 reception, can judge in this, in voltage source switch controller electric power system, whether abnormal power module 4 exports.Middle voltage source switch controller 1 is also for comparing the current signal and the alarm current value of middle voltage source switch controller 1 internal preset that signal of telecommunication receiver module 2 receives, when the current signal value that the alarm current value preset is large and signal of telecommunication receiver module 2 receives, middle voltage source switch controller 1 triggered alarm 6 is reported to the police.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that these only illustrate, protection range of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these execution modes, but these change and amendment all falls into protection range of the present utility model.
