Abstract
The utility model provides a distribution box emergency lighting device which comprises a distribution box body and an emergency lighting device. The emergency lighting device is mounted above the inside of the distribution box body; the emergency lighting device comprises a short circuit protection unit, a time interval charging unit, an LED (Light-emitting Diode) charging unit, a discharge conversion unit and a door-opening lighting-on unit mutually coupled and connected. An alternative time relay is adopted as the time interval charging unit. When the distribution box (cabinet) is wrong, the distribution box (cabinet) can provide light to operating personnel for lighting independently through the emergency lighting device so as to avoid incorrect manipulation accidents and electric shock accidents of the operating personnel caused by insufficient beams. A distribution box (cabinet) emergency lighting system can timely provide light for the working personnel timely for about two hours under the conditions that the distribution box (cabinet) and a distribution room are cut off from power simultaneously, so that the working personnel can overhaul and construct conveniently so as to guarantee the safety.
Description
Technical field
The utility model relates to the high and low voltage electric distribution apparatus field, particularly a kind of distribution box emergency lighting device.
Background technology
Old-fashioned distribution box (cabinet) does not generally have maintenance emergency lighting in the cabinet, therefore in maintenance process, can bring a lot of inconvenience, as:
One, under the situation of distribution box (cabinet) fault, bad because of light, cause danger coefficient high;
Two, in the charged situation of distribution (cabinet) case, operating personnel operate in cabinet, as easy as rolling off a logly cause maloperation, thereby cause inner accident and outside accident;
Three, at distribution box (cabinet) aspect the maintenance, generally need two people, people's operation, a personal emergency (protection).If one of them people gives people's illumination of maintenance again when emergent, break down this moment, certainly will influence the promptness of emergency measure;
Four, under the situation of civil power dead electricity, maintenance does not have illumination, if unexpected at this moment incoming call, danger coefficient is high.
The utility model content
The purpose of the utility model be to provide a kind of can be in the situation that lose extraneous power supply supply, rely on self electric power that the distribution box emergency lighting device of illumination is provided.
The utility model distribution box emergency lighting device comprises: distribution box body; Emergency lighting device, said emergency lighting device are installed in the inner top of said distribution box body; Said anxious lighting device comprises short-circuit protection unit, time interval charhing unit, LED driver element, the converting unit of discharging that mutual coupling connects, lighting unit opens the door.What said time interval charhing unit adopted is the alternate type time relay.
The utility model distribution box emergency lighting device is under the situation of distribution box (cabinet) fault, and distribution box (cabinet) can self provide light to operating personnel's illumination, thus misoperation fault, the electric shock accidents of having avoided operating personnel to cause because of insufficient light.Under the situation of distribution box (cabinet) dead electricity, simultaneously also under the situation of dead electricity, power distribution cabinet (case) maintenance emergency lighting system in time provides the illumination about 2 hours to the staff to power distribution room, with maintenance, the construction that makes things convenient for the staff, guarantees safety.Aspect the maintenance, generally need two people at distribution box (cabinet), people's operation, a personal emergency (protection).If one of them people gives people's illumination of maintenance again when emergent, break down this moment, certainly will influence the promptness of emergency measure, and this emergency lighting has been arranged, and the monitoring personnel can attentively guard, and increase constructor's safety coefficient greatly.

The specific embodiment
Below in conjunction with accompanying drawing the utility model distribution box emergency lighting device is done further explain.
Like Fig. 1, shown in Figure 2, the utility model distribution box emergency lighting device is installed in the emergency lighting device 2 of the top of distribution box body 1 inside.Comprise operating circuit in the emergency lighting device 2, during work, mains supply L is through short-circuit protection unit 3; KA coil in the time interval charhing unit 4 gets electric, the KT coil simultaneously electric, this moment, power supply began power supply for LED driver element 5; LED drives output, and (get because of the KA coil this moment through the KA of overdischarge converting unit 6 normally opened contact; So the trap of often bursting at the seams of KA is closed), the normally-closed contact of process KT is given lithium cell charging this moment to lithium battery E again; The travel switch SQ in the lighting unit 7 of opening the door is normally closed to supply power to led light source.KT in the circuit is the cycle alternation type time relay, generally establishes conversion in 99 hours and opens and 99 hours passes, and each civil power dead electricity is first charged state under the situation of sending electricity, so can but protect the normal guarantee power supply of power supply E.
Under the situation of mains supply L dead electricity, the normally opened contact of KA breaks off, and can ensure that like this redundant electrical power E does not oppositely send electricity to the LED driving, strengthens lithium battery and effectively uses often.
Travel switch SQ is a small-sized microswitch that opens the door, and has only under the situation that the user opens the door and could connect light source H, and SQ is in off-state under the situation that does not have to open when cabinet door and chamber door.
The preferred embodiment of below the utility model having been created specifies; But the utility model is not limited to said embodiment; Those of ordinary skill in the art also can make all modification that is equal to or replacement under the prerequisite of the invention spirit, modification that these are equal to or replacement all are included in the application's the scope.
