Abstract
The utility model discloses a kind of intelligent substation illumination equipment, this intelligent substation illumination equipment comprises a road AC power and a road DC power supply also realizes conversion automatically, described AC power is through circuit breaker Q F1, be connected in series to rectifier U1, AC power is rectified into direct current, is then connected in series to contactor KM1 end of incoming cables; Described DC power supply is through circuit breaker Q F2, and be connected in series to contactor KM2 end of incoming cables, KM1, KM2 leading-out terminal is also connected to KM3 end of incoming cables, and KM3 leading-out terminal receives emergency light.Owing to adopting a road AC power and a road DC power supply also to realize conversion automatically, can keep emergency lighting electricity consumption, the voltage that can not affect again the direct current operative power source of switchgear house significantly declines, and has safe and reliable advantage.
Description
Technical field
The utility model relates to a kind of lighting apparatus, particularly relates to a kind of Emergency Lighting Supply of switchgear house.
Background technology
At switchgear house except conventional illumination is set, also will emergency lighting be set.So-called emergency lighting refers to when switchgear house has an accident dead electricity, a kind of illumination adopting direct current supply.Emergency lighting is used for electric operation under accident condition, accident treatment and maintenance of equipment, and the emergency lighting power supply in switchgear house is got at present to come from and specialized in power distribution station operation, the power supply that the DC cabinet of relaying protection provides.Because in switchgear house, the capacity of storage battery is limited, if in the state of accident, emergency lighting power supply is provided for a long time and maintains power supply needed for control of power supply system signal, storage battery can be made to be pressed in amplitude decline, affect the electric recovery operation after accident treatment, because of a little, in fact the DC power cabinet in switchgear house is adopted to be the needs that really cannot meet emergency lighting as emergency lighting power supply.
In order to emergency lighting electricity consumption can be kept, the voltage that can not affect again the direct current operative power source of switchgear house significantly declines, both economical method does not take the special DC cabinet power supply of electric power system, use a kind of DC-AC two-use power supply instead and have emergency luminaire, this light fixture band dry cell itself, when civil power loses for some reason, the dry battery power that light fixture carries can be enabled automatically, thus the DC control supply of switchgear house can not be affected.
Summary of the invention
The purpose of this utility model is to provide the intelligent substation illumination equipment that a kind of alternating current-direct current is changed automatically.
The purpose of this utility model is achieved through the following technical solutions, this intelligent substation illumination equipment comprises a road AC power and a road DC power supply also realizes conversion automatically, described AC power is through circuit breaker Q F1, be connected in series to rectifier U1, AC power is rectified into direct current, is then connected in series to contactor KM1 end of incoming cables; Described DC power supply is through circuit breaker Q F2, and be connected in series to contactor KM2 end of incoming cables, KM1, KM2 leading-out terminal is also connected to KM3 end of incoming cables, and KM3 leading-out terminal receives emergency light.
Described SB1 is scram button, and SB2 is manual automatic transfer switch.
Its operation principle is: forward manual position to, available SB3, SB4 pushbutton enable and the conventional power supply KM1 of stopping, and SB5, SB6 stop stand-by power supply KM2 automatically, forward automated location to, conventional power supply KA1 relay adhesive, KA1 normally opened contact starts the KT1 time relay, through time delay, KT1 starts KM1 contactor, when conventional power supply loses point, KA1 relay disconnects, KA1 normally-closed contact starts the KT2 time relay, KM2 contactor and KA2 relay is started through time delay KT2, KA2 relay starts KT3 time delay relay for subsequent use, when the time that stand-by power supply sets more than the KT3 time relay discharge time, the action of KT3 normally-closed contact disconnects KM2, prevent storage battery over-discharge from damaging storage battery, KM1, KM2 interlocks, guarantee can only adhesive one tunnel.
SB7 emergency light manual automatic transfer switch, manual position SB8, SB9 stop starting KM3 contactor.Automated location, KM3 through irritated switch control rule, when darkness reaches the setting of photosensitive switch, photosensitive switch action launching KM3, KM3 adhesive automatic lighting lamp.
The beneficial effects of the utility model: owing to adopting a road AC power and a road DC power supply also to realize conversion automatically, can keep emergency lighting electricity consumption, the voltage that can not affect again the direct current operative power source of switchgear house significantly declines, and has safe and reliable advantage.
Accompanying drawing explanation
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing
Fig. 1 is inlet wire duplicate supply schematic diagram of the present utility model
Fig. 2 is emergency light control principle drawing of the present utility model
Embodiment
As shown in Figure 1, 2, this intelligent substation illumination equipment comprises a road AC power and a road DC power supply also realizes conversion automatically, and described AC power, through circuit breaker Q F1, is connected in series to rectifier U1, AC power is rectified into direct current, is then connected in series to contactor KM1 end of incoming cables; Described DC power supply is through circuit breaker Q F2, and be connected in series to contactor KM2 end of incoming cables, KM1, KM2 leading-out terminal is also connected to KM3 end of incoming cables, and KM3 leading-out terminal receives emergency light.Its operation principle is: forward manual position to, available SB3, SB4 pushbutton enable and the conventional power supply KM1 of stopping, and SB5, SB6 stop stand-by power supply KM2 automatically, forward automated location to, conventional power supply KA1 relay adhesive, KA1 normally opened contact starts the KT1 time relay, through time delay, KT1 starts KM1 contactor, when conventional power supply loses point, KA1 relay disconnects, KA1 normally-closed contact starts the KT2 time relay, KM2 contactor and KA2 relay is started through time delay KT2, KA2 relay starts KT3 time delay relay for subsequent use, when the time that stand-by power supply sets more than the KT3 time relay discharge time, the action of KT3 normally-closed contact disconnects KM2, prevent storage battery over-discharge from damaging storage battery, KM1, KM2 interlocks, guarantee can only adhesive one tunnel.SB7 emergency light manual automatic transfer switch, manual position SB8, SB9 stop starting KM3 contactor.Automated location, KM3 through irritated switch control rule, when darkness reaches the setting of photosensitive switch, photosensitive switch action launching KM3, KM3 adhesive automatic lighting lamp.
