Abstract
A simple power failure automatic switching apparatus. An apparatus protective housing adopts a PC material of high insulation strength, flame retardation and corrosion resistance and is internally provided with a switching control panel. The control panel comprises multi-contact heavy current relays, a fuse which prevents surge voltage and current, and a surge absorber. The beneficial effects of the simple power failure automatic switching apparatus are that by additionally arranging the apparatus and a standby power supply, overall average non-failure time of equipment is more than double, an average service life of the equipment is prolonged to more than double, and maintenance and repair cost of the equipment are greatly reduced at the same time.
Description
Technical field
The utility model relates to a easy power failure automatic switching control equipment, is specially adapted to that the inconvenience of some power supplys is changed, uses on the equipment of power supply maintenance difficult, especially can be used as LED lamp power servicing unit and uses.
Background technology
At present, generally the light fixture of Shi Yonging is mainly single power supply, is example with the LED light fixture, and the integrated substantially or modular mode of power supply is used, and this kind supply power mode has advantage such as easy to connect, with low cost.But the LED light fixture the link that the most easily breaks down as light fixture integral body of driving power, the MTBF time that can reduce whole lamp greatly.In some particular application, as tunnel, highway, mountain area, outlet light fixture etc.,, power supply cause light fixture to lose efficacy in case breaking down, and keeping in repair, replacing with and can cause great inconvenience, need a large amount of manpower and materials of cost to deal with problems.The corresponding contingency occurrence probability that light fixture inefficacy simultaneously may cause also can improve relatively.
Summary of the invention
In order to remedy deficiency and the hidden danger on the above occupation mode, the utility model relates to a easy power failure automatic switching control equipment.This device such as can be installed in the wall, lamp stand, light fixture easily at the position, when using this device, can increase a stand-by power supply and cooperate main power source to use.This device automatically starting stand-by power supply is the light fixture power supply when main power source breaks down, and cuts off main power source supply line simultaneously, in order to avoid cause unnecessary interference.
The technical scheme that its technical scheme that solves the utility model adopts is: the unit protection shell adopts high insulation resistance, fire-retardant, corrosion resistant PC material; the inner conversion and control plate of placing; comprise multifinger high-current relay on the control board, prevent the fuse and the surge absorber of surge voltage, electric current.Contain six input/output ports simultaneously, connect input, the output of high pressure input, main power source and stand-by power supply respectively, and the delivery outlet that connects light fixture.There are red, green two LED light at high voltage input terminal mouth place, and when main power source was worked, green indicating lamp was lighted; When stand-by power supply was worked, red led was lighted, and can in time find fault like this when overhaul of the equipments, in time changed, and avoided light fixture complete failure.
The beneficial effects of the utility model are, only need to increase this device and a stand-by power supply, the average accident-free duration that can increase light fixture integral body is more than 1 times, and it is original more than two times promptly improving equipment average life, has greatly reduced light fixture maintenance, repair cost simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model.
Fig. 2 is a left view of the present utility model.
Fig. 3 is a rearview of the present utility model.
Fig. 4 is the assembled configuration figure of device integral body.
Fig. 5 is circuit theory diagrams of the present utility model.
1. green light LED indicator lights among the figure; 2. red-light LED indicator light, 3. high voltage input terminal, 4.PC insulation crust loam cake; 5. main power source high voltage input terminal; 6. main power source low-voltage output, 7.PC insulation crust lower cover, 8. output; 9. relay; 10. protective circuit, 11. stand-by power supply high voltage input terminal, 12. stand-by power supply low-voltage outputs.
Embodiment
In Fig. 1, Fig. 2, Fig. 3, high voltage input terminal 3, main power source high voltage input terminal 5, main power source low-voltage output 6, output 8, green light LED indicator light 1, red-light LED indicator light 2, stand-by power supply high voltage input terminal 11, stand-by power supply low-voltage output 12 place four sides of PC insulation crust loam cake 4 respectively, and the main power source respective side is the stand-by power supply input/output terminal.During the light fixture operate as normal, be the main power source power supply, this moment, the green light LED indicator light 1 was lighted, and main power source breaks down, and when device can't detect normal main power source output, device can automatically switch to stand-by power supply work, and this moment, the red-light LED indicator light 2 was lighted.This function can point out the attendant normally patrolling and examining in the process, in time pinpoints the problems, and changes trouble power, thereby guarantees that light fixture does not in use have whole lamp failure phenomenon.
In assembling schematic diagram shown in Figure 3, PC insulation crust lower cover 7 uses tapping screw fastening with control circuit board, and enough insulation distances are left in control circuit board and insulation crust bottom, insulation crust side, prevent that circuit is creepage, cause unexpected injury.High voltage input terminal 3, main power source and stand-by power supply input/output terminal all use the binding post mode to be welded to control circuit board, can reach firm, durable effect.Integrated protective tube and antisurge device in the protective circuit 10, cut-out circuit when equipment suffers as failure and special such as thunderbolts, thus can protect the power supply that is connected on the device can not damage.Relay 9 is the switching device of controller, plays the transformation of main power source and stand-by power supply in circuit.
In the circuit theory diagrams of Fig. 5; the operation principle that has comprised control circuit board is at first placed protective circuit 10 in high voltage input terminal, prevents overcurrent, the overvoltage of electric power system; after the power supply power supply; because relay 9 is in normally open, thus two power supplys can start simultaneously, treat that the main power source electric power output voltage reaches the starting resistor of relay 9 after; relay 9 starts; the input and output contact of control stand-by power supply disconnects, and main power source is powered to light fixture, lights green light LED indicator light 1 simultaneously.Because relay 9 is very low with indicator light 1 power, so can ignore to the influence of luminaire efficiency.When main power source broke down, relay 9 stopped action, the closing of contact, and stand-by power supply is started working, and main power source output simultaneously disconnects, and red-light LED indicator light 2 is lighted.At this moment, the equal consumed power not of device does not have any influence to luminaire efficiency in the equipment, and after Awaiting Overhaul was changed normal power source, fault can be removed, and device recovers normal operating conditions.
