Background technology
Ring main unit is one group of transmission ＆ distribution electrical equipment（High-tension switch gear）In metal or non-metallic insulation cabinet or doInto the electrical equipment of assembled compartment ring network power supplying units, its core uses on-load switch and fuse, has structure letterIt is single, small, price is low, can improve the advantages that power supply parameter and performance and power supply safety.It is widely used in city and livesIn the power distribution station and box-type substation of the load centers such as residence cell, skyscraper, large public building, factory and enterprise.
In the prior art, lighting device is installed, but the lighting device needs operating personnel to open looped network in ring main unitCabinet finds bull switch, if surrounding enviroment illumination is dark, operating personnel easily touch when bull switch is gropedOther switches are touched, cause security risk.
Utility model content
The purpose of this utility model is to provide a kind of looped network case with automatic illuminating apparatus, it can be certainly when cabinet door is openedDynamic to open headlamp, avoiding operating personnel from finding controlling switch causes false touch.
The above-mentioned technical purpose of the utility model technical scheme is that：
A kind of looped network case with automatic illuminating apparatus, including cabinet and cabinet door, the cabinet are equipped with bending mechanism, instituteState bending mechanism and be equipped with headlamp, the cabinet inner wall, which is located at cabinet door closure, is equipped with normally closed microswitch K, the cabinet door inWhen being closed on the cabinet, the normally closed microswitch K is disconnected, and the headlamp is controlled by control circuit.
Further, the control circuit includes a triode Q, and the base stage of the triode Q is opened with the normally closed fine motionClose K to be electrically connected, the collector of the triode Q is electrically connected with the second direct current V2, the repellel concatenation illumination of the triode QConnect after lamp.
Further, the normally closed microswitch K is electrically connected startup power supply, and the startup power supply is the first direct current V1.
Further, power circuit is further included, the power circuit inputs 220V alternating currents, exports the first direct current of 5VThe second direct current V2 of V1 and 12V.
Further, the inner wall of the cabinet is equipped with electrical appliance kit, and the control circuit is arranged on the electric appliance with power circuitIn box.
Further, the normally closed microswitch K is equipped with button, and the cabinet inner wall, which is equipped with, accommodates the recessed of the buttonGroove, the button are equipped with the inclined-plane that cabinet opening is slipped into easy to cabinet door.
Further, the bending mechanism includes metal hose, and it is soft that the electric wire being connected with the headlamp is arranged in metalIn pipe.
Further, the headlamp is LED light.
In conclusion the utility model has the advantages that：
(1) by the setting of normally closed microswitch, when cabinet door closes, normally closed microswitch in opened condition, headlampDo not work, and when cabinet door is opened, normally closed microswitch closure makes control circuit path, headlamp lights, so as to avoid operatorMember gropes controlling switch and false touch other switches cause security risk；
(2) headlamp is connected by bending mechanism with cabinet inner wall, make headlamp according to operating personnel need illuminate phaseAnswer position.

Embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only explanation to the utility model, it is not the limitation to the utility model, abilityField technique personnel as needed can make the present embodiment the modification of no creative contribution after this specification is read, butAs long as within the protection scope of the present utility model all protected be subject to Patent Law.
A kind of looped network case with automatic illuminating apparatus, as shown in Figure 1, including cabinet 1 and cabinet door 2, cabinet 1 is equipped with curvedMechanism 3 is rolled over, as shown in Fig. 2, bending mechanism 3 is equipped with headlamp 4,1 inner wall of cabinet, which is located at 2 closure of cabinet door, is equipped with normally closed fine motionK is switched, when being closed on cabinet 1, normally closed microswitch K is disconnected cabinet door 2, and headlamp 4 is controlled by control circuit 5.
By the setting of normally closed microswitch, when cabinet door 2 closes, in opened condition, headlamp 4 is or not normally closed microswitchIt is bright, and when cabinet door 2 is opened, normally closed microswitch closure makes 5 path of control circuit, headlamp 4 lights, so as to avoid operatingPersonnel grope controlling switch and false touch other switches cause security risk.
As shown in Figure 1, normally closed microswitch K is equipped with button 8,1 inner wall of cabinet is equipped with the groove for accommodating button 8, button 8It is equipped with the inclined-plane 81 that the opening of cabinet 1 is slipped into easy to cabinet door 2.When cabinet door 2 closes, the side pressable button 8 of cabinet door 2 it is obliqueFace 81, makes button 8 enter groove, disconnects normally closed microswitch K.
The inner wall of cabinet 1 is provided with electrical appliance kit 7, and control circuit 5 and power circuit 6 are provided with electrical appliance kit 7.
As shown in figure 3, control circuit 5 includes a triode Q, the base stage of triode Q is electrically connected with normally closed microswitch K,The collector of triode Q is electrically connected with the second direct current V2, is connect after the repellel concatenation headlamp 4 of triode Q.Normally closed fine motionSwitch K and be electrically connected startup power supply, startup power supply is the first direct current V1.As shown in figure 4, power circuit 6 inputs 220V alternating currents,Export the second direct current V2 of the first direct current V1 and 12V of 5V.
3 bending mechanism 3 of bending mechanism includes metal hose, and the electric wire being connected with headlamp 4 is arranged in metal hose.MakeHeadlamp 4 can need to illuminate corresponding position in cabinet 1 according to operating personnel.Headlamp 4 uses LED in the present embodimentLamp.Common light bulb can be also used in other embodiments.
