Anxious illumination.
Transformer station's emergency lighting system that this utility model provides, including: alternating current power supply, DC source,
Distribution box and illuminating lamp, alternating current power supply is that illuminating lamp is powered, when intelligence switch unit monitors alternating current
After source disappears, by inverter, transfer the unidirectional current that the DC source being attached thereto exports to exchange
Electricity continues as illuminating lamp and provides alternating current power supply, solves the DC power cabinet in employing switchgear house as thing
Therefore Emergency Lighting Supply is the problem that cannot really meet emergency lighting needs, and emergency light also makes
Power by alternating current power supply, it is to avoid different illuminating lamp models and performance requirement are to Substation Design, construction
The difficulty brought with maintenance.
Accompanying drawing explanation
In order to make content of the present utility model be more likely to be clearly understood, below according to this utility model
Specific embodiment and combine accompanying drawing, this utility model is described in further detail, wherein
Fig. 1 is that a kind of transformer station emergency lighting system internal structure that this utility model embodiment provides is shown
It is intended to.
Detailed description of the invention
The present embodiment provides a kind of transformer station emergency lighting system, as it is shown in figure 1, alternating current power supply 1, straight
Stream power supply 2, illuminating lamp 4, intelligence switch unit 31 and inverter 32；Wherein, alternating current power supply 1
For providing alternating current for illuminating lamp 4, when intelligence switch unit 31 monitors alternating current power supply power-off,
Utilize inverter 32 to transfer the unidirectional current that the DC source of connection provides to alternating current and continue as illuminating lamp
4 power supplies.
Transformer station's emergency lighting system that this utility model embodiment provides, when intelligence switch unit monitoring
After disappearing to alternating current power supply, by inverter, the unidirectional current that the DC source being attached thereto is exported
Transfer alternating current to and illuminating lamp offer alternating current power supply is provided, solve the DC source in employing switchgear house
Cabinet is the problem that cannot really meet needs as accident emergency mains lighting supply.
Intelligence switch unit 31 can be integrated in distribution box 3 with inverter 32, it is also possible to distribution
Case 3 is arranged in parallel in alternating current and galvanic inlet wire circuit, for the ease of wiring, the present embodiment
Preferably intelligence switch unit 31 and inverter 32 are integrated in distribution box 3.Alternating current power supply 1 can
To cause station AC low voltage power switch panel, after being distributed by distribution box, for electric equipment chamber in transformer station
The corresponding illuminating lamp 4 of emergency lighting system provides alternating current, electric equipment chamber can be GIS room,
Capacitor chamber, relay bungalow, transformer room, can also carry for the indicating lamp for emergency in transformer station simultaneously
For illumination；DC source 2 is caused station DC power supply panel or is transferred to by external communication electricity by commutator
Unidirectional current, provides DC source then, and the present embodiment preferably causes station DC source, when intelligence is cut
Change unit 31 and monitor alternating current power supply power-off, make the inverter circuit in inverter 32 will be connected to direct current
