The utility model has the advantages that the special power saving system device for road lamp has power supply of two paths, to satisfy different voltage demands in the start and the normal-on period of road lamp, the delay relay and the commutator can automatically switch the power supply of two paths, and the power saving shifts can be automatically changed by setting times via a time control switch and a phase-shifting transformer.
Description
Technical field
The utility model relates to power saving apparatus, more specifically says, it relates to a kind of street lamp private section electric system device.
Background technology
All there is tangible peak valley in each city electricity consumption of China, and the change in voltage of urban district electricity consumption peak phase and paddy phase is more outstanding again.Such as falling sharply at the commercial power consumption of midnight resident and enterprise, be tending towards the paddy phase, line loss reduces, and voltage increases in the supply line at this moment.The street lamp control system light efficiency of prior art is lower, and useful life is short.Can not realize the Based Intelligent Control of street lamp, can't respectively the power of street lamp be regulated and control according to the required illumination difference of different time periods and the variation of supply power voltage.Also have some to reduce power consumption by reducing voltage, its outstanding problem is an electric light starter difficulty after the step-down, also damages street lamp easily.
Summary of the invention
The purpose of this utility model is to overcome deficiency of the prior art, provides a kind of rational in infrastructure, can adjust power at times, and is effectively energy-conservation, the street lamp private section electric system device of long service life.
The purpose of this utility model is achieved through the following technical solutions.This street lamp private section electric system device, it is series on the main circuit three-phase electricity of street lamp, comprise a circuit breaker of connecting with main circuit three-phase electricity input, circuit breaker other end tap first branch road and second branch road, wherein first branch road connect successively the economize on electricity contactor, shift to transformer, second branch road series connection city electric contactor, first branch road and second branch road are terminal connects with main circuit three-phase electricity output, the economize on electricity contactor links to each other with change over switch with city's electric contactor control end, is connected with the time relay between change over switch control end and the economize on electricity contactor.
As preferably, to shift to transformer and be provided with at least two gears, the gear control end is connected with time switch.
As preferably, the first branch road end is connected with capacitor by capacitor switching contactor.
Owing to adopt technique scheme, street lamp private section electric system device of the present utility model is by the employing design of supplying power with double circuit, when having solved the street lamp startup with of the different requirements of normal bright stage to voltage; By adopting the automatic switchover that realized supplying power with double circuit of time-delay relay and change over switch; By adopting time switch and phase shifting transformer, the economize on electricity gear can be by automatic conversion of time period is set.Street lamp can be lighted at first, avoid early stage because of the too low defective that can not start street lighting of voltage; And afterwards in service, can according to the time period to the different gears that economize on electricity that automatically switch of the requirement of illumination, do not need the special messenger to guard.And local compensation power factor.

Embodiment
Below in conjunction with drawings and Examples the utility model is described further.Though the utility model will be described in conjunction with preferred embodiment, should know, do not represent that the utility model is limited among the described embodiment.On the contrary, the utility model will be contained alternative, modified model and the equivalent in the scope of the present utility model that can be included in attached claims qualification.
Referring to Fig. 1-2, the street lamp private section electric system device of Jie Shaoing generally is used for the street lamp power supply, road lamp power supply circuit here, yet should know that the utility model also can be used for other power supply circuits that same demand is arranged etc.This street lamp private section electric system device, it is series on the main circuit three-phase electricity of street lamp, comprise a circuit breaker 1 of connecting with main circuit three-phase electricity input, circuit breaker 1 other end tap, first branch road and second branch road, wherein first branch road connect successively the economize on electricity contactor 3, shift to transformer 4, second branch road series connection city electric contactor 2, first branch road and second branch road are terminal connects with main circuit three-phase electricity output, economize on electricity contactor 3 links to each other with change over switch 10 with city's electric contactor 2 control ends, is connected with the time relay 11 between change over switch 10 control ends and the economize on electricity contactor 3.Shift to transformer 4 and be provided with three gears, be followed successively by first gear 6, second gear 7, third gear 8, the gear control end is connected with time switch 12.The first branch road end is connected with capacitor 9 by capacitor switching contactor 5.
In former main circuit, three-phase electricity is crossed circuit breaker 1 back and is divided two-way with this device serial connection, and one tunnel contactor 3 that advances to economize on electricity by phase shifting transformer 4, utilizes contactor 5 to incorporate capacitor 9 into, picks out illuminating street lamp; One the tunnel advances city's electric contactor 2, picks out illuminating street lamp.This two-way switches to be controlled by change over switch 10.When selecting electricity-saving state, at first enter circuit by civil power, make the normal startup of street lamp shinny, then by the time relay 11 time-delays, 3 adhesives of envoy's electric contactor, city's electric contactor 2 disconnects, and enters economize on electricity gear first gear 6.Then by time switch 12, according to the time period difference, needed illumination difference is selected automatically to the economize on electricity gear accordingly.Street lamp can be lighted at first, avoid early stage because of the too low defective that can not start street lighting of voltage; And afterwards in service, can according to the time period to the different gears that economize on electricity that automatically switch of the requirement of illumination, do not need the special messenger to guard.And local compensation power factor.
