An intelligent time and light perception controller SK controls an intermediate relay KA1 and an intermediate relay KA2 according to time and light; a normally open contact of the intermediate relay KA1 controls an all-night street lamp contactor KM1; a normally close contact of the intermediate relay KA1 controls a step-up grade of an on-load switch controller HMK of a transformer; a normally open contact of the intermediate relay KA2 controls an midnight street lamp contactor KM2; a normally close contact of the intermediate relay KA2 controls the step-up grade of the on-load switch controller HMK of the transformer; and a normally open contact of the intermediate relay KA2 controls a step-down grade of the on-load switch controller HMK of the transformer. The utility model has the characteristics of simple structure, intelligent control, energy conservation and the like.

Description

The energy-conserving intelligent street lamp control system

Technical field

The utility model relates to a kind of street lamp control system.

Background technology

The street corner street lamp generally be divided into full night street lamp and midnight two groups in street lamp, the transitional street lamps control system can't be according to the street lamp loading condition, automatically the transformer tapping range is adjusted in control, making the street lamp load terminal voltage remain on rated voltage allows within the fluctuation range, and when the street lamp load reduces, can't reduce the no-load loss of transformer, waste electric energy greatly.

Summary of the invention

For solving the problems referred to above that existing street lamp control system exists, the utility model provides a kind of energy-conserving intelligent street lamp control system, and its technical scheme of taking is:

This control system comprises time and light sensation intelligent controller SK, auxiliary relay KA1, auxiliary relay KA2, full night street lamp contactor KM1, midnight street lamp contactor KM2 and transformer loaded switch controller HMK, time and light sensation intelligent controller SK are according to time and light control auxiliary relay KA1 and auxiliary relay KA2, control street lamp contactor KM1 at full night the normal battle of auxiliary relay KA1, the shelves that boost of the normally closed point control transformer loaded switch controller HMK of auxiliary relay KA1, control street lamp contactor KM2 at midnight the normal battle of auxiliary relay KA2, the shelves that boost of the normally closed point control transformer loaded switch controller HMK of auxiliary relay KA2, auxiliary relay KA2 normal battle control transformer loaded switch controller HMK the step-down shelves.

Time and light sensation intelligent controller SK are when controlling road lamp switch automatically, according to loading condition, automatically the transformer tapping range is adjusted in control, making street lamp (load) terminal voltage remain on rated voltage allows within the fluctuation range, make the transformer flux variable density simultaneously, when the street lamp load reduced, magnetic flux density was along with reduction, thus the no-load loss of reduction transformer.

Therefore the utlity model has simple in structurely, realize Based Intelligent Control, characteristics such as energy savings.

Description of drawings

Fig. 1 is control circuit figure of the present utility model;

Fig. 2 is the application circuit of an embodiment.

Embodiment

Below in conjunction with accompanying drawing the utility model is described further:

As shown in Figure 1, this control system is applied in the control street lamp with on the prepackage box-type substation, this transformer station comprises equipment such as high and low voltage switch equipment, control appliance and on-load tap-changing transformer, and the control by time and light sensation intelligent controller SK is to the street lamp transmission of electric energy.Time and light sensation intelligent controller SK are according to time and light control auxiliary relay KA1 and auxiliary relay KA2, control street lamp contactor KM1 at full night the normal battle of auxiliary relay KA1, the shelves that boost of the normally closed point control transformer loaded switch controller HMK of auxiliary relay KA1, control street lamp contactor KM2 at midnight the normal battle of auxiliary relay KA2, the shelves that boost of the normally closed point control transformer loaded switch controller HMK of auxiliary relay KA2, auxiliary relay KA2 normal battle control transformer loaded switch controller HMK the step-down shelves.Every day 18:00-0:00 when full night street lamp and midnight street lamp complete when bright, transformer moves in specified tap, only complete when night, street lamp was bright when the time period at 0:00-6:00, auxiliary relay KA2 action, midnight, street lamp extinguished, auxiliary relay KA2 control transformer loaded switch controller HMK simultaneously boosts to+5% tap, when the time period at 6:00-18:00, auxiliary relay KA1 action, street lamp all extinguishes, auxiliary relay KA1 controls HK transformer loaded switch controller HMK simultaneously and boosts to+and 7.5%, street lamp is bright entirely during 18:00, and KA2 controls HK transformer loaded switch controller HMK simultaneously and is depressurized to specified tap.

As shown in Figure 2, with high pressure 10kV, low pressure 0.4kV, capacity are the transformer of 400kVA, and no-load loss is 570W, control 20 street lamps, and every 500W is an example, wherein 10 street lamps be full night bright (18:00-6:00) wherein 10 be midnight bright (18:00-0:00).When pressure regulation was to+5% tap when evening lamp is closed, this moment, the high-pressure side line voltage was constant, still was 10kV, and because of coil turn increases by 5%, street lamp side voltage is for being depressurized to 380V, and transformer noload losses is reduced to original 0.85 times; Reduce 85.5W, reduce load 5000W simultaneously.When pressure regulation was to+7.5% tap when full night-light is closed, this moment, the high-pressure side line voltage was constant, still was 10kV, and because of coil turn increases by 7.5%, street lamp side voltage is for being depressurized to 370V, and transformer noload losses is reduced to original 0.8 times; Reduce the about 114W of about energy consumption, reduce load 10000W simultaneously.
