Abstract
The utility model discloses an energy saving device of a street lamp, which comprises two or more than two interlocking contactors; the upper end of each interlocking contactor is respectively connected with the output end of a transformer; the lower end of each interlocking contactor is connected in parallel with load of the street lamp; a controller controls the interlocking contactors to continually switch over a power supply; the controller can be used as a wireless remote receiving controller and a microcomputer time control switch. The utility model has the advantages that multiple stages of voltage supplies power; in order to use one kind of voltage to supply power, the interlocking contactors are continually switched over to ensure the purposes of power supply, voltage regulation, voltage reduction and energy saving of the street lamp.
Description
Technical field
The utility model relates to a kind of road lamp device, especially a kind of energy-saving device for road lamp.
Background technology
Street lamp dedicated transformer (three-phase is single-phase) low pressure output phase voltage is fixed as 220 volts at present.Output voltage changes with grid voltage change again, and during electricity consumption at midnight ebb, the low pressure output voltage rises sometimes and reaches 250 volts.The sodium vapor lamp that road lighting is used, Metal halogen lamp, gaseous discharge lamps such as mercury lamp raise with voltage, and electric current increases, and luminosity strengthens, on the contrary the voltage reduction, electric current reduces, and luminosity weakens.The high voltage operation causes power supply cost to strengthen, and has also shortened the useful life of ballast and bulb greatly.According to investigations, China small and medium-sized cities after 12 of midnights, also rare pedestrian, vehicle on the road behind the large size city 2:00 AM.After this period, still keep high illumination obviously to there is no need on the road.
Summary of the invention
The technical solution of the utility model is: a kind of energy-saving device for road lamp, comprise the interlocking contactor more than two or two in this energy-saving device for road lamp, the upper end of every All-China Federation of Taiwan Compatriots latch contact connects the output of transformer respectively, the lower end of interlocking contactor also is attached to the street lamp load, controller control interlocking contactor.Make the free of discontinuities Switching power by controller control interlocking contactor, controller can receive controller control switch also can be for microcomputer the time for wireless remote control.The length of the push rod on the auxiliary break contact on the interlocking contactor can be set arbitrarily, to regulate deciliter time.
Advantage of the present utility model is: multi-voltage grade power supply, and have only to switch and guarantee street lamp power supply, road lamp power supply and voltage stabilizing, the energy-conservation target of step-down for reaching a power voltage supply by interlocking contactor free of discontinuities.
Description of drawings
Fig. 1 is the utility model energy-saving device for road lamp structural representation;
Fig. 2 is auxiliary moving disconnected (normally closed) contact schematic diagram on the utility model energy-saving device for road lamp interlocking contactor.
Embodiment
Street lamp dedicated transformer 2 is made many taps, the transformer of multi-voltage grade.Whenever, make three voltages mutually, voltage request should ground and decide, and is about 220V, 200V, three ranks of 180V.
A kind of energy-saving device for road lamp, comprise the interlocking contactor 1 more than three in this energy-saving device for road lamp, the upper end of every All-China Federation of Taiwan Compatriots latch contact 1 connects the output of transformer 2 respectively, and the lower end of interlocking contactor 1 also is attached to street lamp 3 loads, microcomputer time switch 4 control interlocking contactors 1.Make the free of discontinuities Switching power by microcomputer time switch 4 control interlocking contactors 1, by the opening and closing of microcomputer time switch 4 control interlocking contactors 1.The length of the push rod 5 on auxiliary moving disconnected (normally closed) contact on the interlocking contactor can be set arbitrarily, to regulate deciliter time.
Operation principle: street lamp opens step-down automatically and cuts out is that control by microcomputer time switch 4 distich latch contact 1 is finished.Now carry out turning on light in one day brownout operation, the operation of turning off the light with microcomputer time switch 4.
Microcomputer time switch 4 time sets: one road 18:00 opens 23:01 and closes
Two road 23:00 open 2:01 and close
Three road 2:00 open 6:00 and close
Bright lamp: during 18:00 during microcomputer control switch 4 riches all the way goes out to control power supply and exchange interlocking contactor 1-1 pull-in winding through auxiliary moving disconnected (normally closed) contact to the first one pole vacuum that the second one pole vacuum exchanges interlocking contactor 1-2, the first one pole vacuum exchanges interlocking contactor 1-1 closure, the main power source 220V bright lamp of switching on.
Voltage stabilizing: during 23:00 during microcomputer control switch 4 two tunnel send the control power supply and exchange auxiliary moving disconnected (normally closed) contact to the second of interlocking contactor 1-3 one pole vacuum through the 3rd one pole vacuum and exchange the interlocking contactor 1-2 pull-in winding second one pole vacuum and exchange interlocking contactor 1-2 closure, main power source 200V power supply, auxiliary moving disconnected (normally closed) contact cuts off the first one pole vacuum simultaneously and exchanges interlocking contactor 1-1 control power supply, and the first one pole vacuum exchanges interlocking contactor 1-1 and disconnects main power source 220V.The 23:01 time switch is closed one tunnel control power supply.
Step-down is energy-conservation: during 2:00 during microcomputer control switch 4 three tunnel send the control power supply, the 3rd one pole vacuum exchanges interlocking contactor 1-3 adhesive main power source 180V power supply, auxiliary moving disconnected (normally closed) contact cuts off the second one pole vacuum simultaneously and exchanges interlocking contactor 1-2 control power supply, and the second one pole vacuum exchanges interlocking contactor 1-2 and disconnects main power source 200V.2:01 microcomputer time switch 4 is closed two tunnel control power supplys.The 6:00 control switch cuts out three tunnel control power supplys, and the 3rd one pole vacuum exchanges interlocking contactor 1-3 cut-out main power source 180V and turns off the light.
Interlocking auxiliary moving (normally closed) breakpoint on the contactor 1 is the core position of two power source conversion, install additional can set any push rod 5 length to regulate deciliter time.Guarantee that first one pole vacuum interchange interlocking contactor 1-1 disconnection exchanges interlocking contactor 1-2 closure and has 0.01 second-0.03 second time difference with the second one pole vacuum.If two one pole vacuum exchange the interlocking contactor closed simultaneously, will have potential difference, produce circulating current.Longer street lamp will extinguish opening time when two one pole vacuum exchange interlocking contactor conversion electric powers, and street lamp needs to start once more.
