Description
Technical field
The utility model relates to the street lighting control field, specifically a kind of street lamp Comprehensive Control case.
Background technology
Streetlight control box has been widely used in the street lighting control field, can automatically open and close street lamp according to ambient light illumination.But common streetlight control box can only open and close all street lamps that are subject to its control simultaneously.And, about when night zero, people's outdoor activity has reduced, streetlight control box can not the closed portion street lamp, reduces outdoor brightness with the conservation of power resource.Particularly, in school, factory and other public place, the quantity of street lamp is more, and cause a large amount of energy waste because can not partly closing night.Therefore, be necessary to design a kind of can be in needs the control cabinet of automatic closed portion street lamp.
The utility model content
The purpose of this utility model is to provide a kind of street lamp Comprehensive Control case, and this control cabinet can open and close street lamp automatically according to ambient light illumination, and at the time closed portion street lamp of setting in advance, to make up deficiency of the prior art.Also be provided with manual control circuit, while detecting for the operational administrative personnel or open temporarily or close street lamp.
The technical solution of the utility model is as follows: a kind of street lamp Comprehensive Control case, comprise the control relay group, described control relay group by the actuating coil of the second A.C. contactor (2KM) with after the time delay break contact (KT-1) of time-delay relay is connected, then with the actuating coil formation in parallel of actuating coil and the time-delay relay (KT) of the first A.C. contactor (1KM); The output of described control relay group is connected to the zero line (N) of AC power, the input of control relay group is connected to the output of light-operated switch (LX) normally opened contact, the input of light-operated switch (LX) normally opened contact is connected to first output (2) of change over switch (ST), and the input (1) of change over switch (ST) is connected to the live wire (L) of AC power; Also comprise manual control circuit, described manual control circuit is parallel to the second auxiliary contact of the first A.C. contactor (1KM) by normally open push button switch (SA), then forms after the normally closed push button switch of connecting (TA); The input of described manual control circuit is connected to second output (3) of change over switch (ST), and output is connected to the input of control relay group.
Use for the ease of the operational administrative personnel, street lamp Comprehensive Control case also is provided with indicating circuit, specific as follows: also comprise the dead electricity indicating circuit, described dead electricity indicating circuit is connected respectively to live wire (L) and zero line (N) formation of AC power by the two ends of the first indicator light (HL-1); Also comprise working indicating, described working indicating is by the second indicator light (HL-2) with after the 4th auxiliary contact (1KM-4) of the first A.C. contactor (1KM) is connected, and live wire (L) and zero line (N) that two ends are connected respectively to AC power form; Also comprise the delay working indicating circuit, described delay working indicating circuit is by the 3rd indicator light (HL-3) with after the 4th auxiliary contact (2KM-4) of the second A.C. contactor (2KM) is connected, and live wire (L) and zero line (N) that two ends are connected respectively to AC power form.
While using street lamp Comprehensive Control case, street lamp need be divided into to two groups.The break-make of first group of street lamp is controlled by the main contact of the first A.C. contactor, and the break-make of second group of street lamp is controlled by the main contact of the second A.C. contactor.If street lamp is powered by three-phase alternating current, should use three-phase ac contactor, now still need all street lamps are divided into to two groups.For the load of balance three-phase alternating current, also the street lamp in each group should be further divided into to three parts, make each part controlled by a main contact of a three-phase ac contactor.The light-operated switch (LX) of street lamp Comprehensive Control case should be arranged on outdoor, not affected by indoor light, with the unlatching that guarantees light-operated switch, the sensitivity of closing.
The control function of street lamp Comprehensive Control case is achieved in that the input 1 of change over switch ST is switched to the first output 2, enters automatic mode.When coming night, the ambient light illumination automatic detection circuit trigger output voltage of light-operated switch LX inside, the normally opened contact closure of light-operated switch LX, the actuating coil of on-delay relay K T makes time delay break contact KT-1 closure, enters the delay working state.Now, the actuating coil of the first A.C. contactor 1KM and the second A.C. contactor 2KM all is switched on, and two A.C. contactor actions, connect its main contact, after the street lamp energising under main contact control, lights.After the prior delay time of setting of time-delay relay KT has arrived, time delay break contact KT-1 automatic disconnection, the actuating coil outage of the second A.C. contactor 2KM, disconnect its main contact, and the street lamp that the main contact of the second A.C. contactor is controlled extinguishes.When after the daybreak in the morning, the ambient light illumination automatic detection circuit of optical controlling switch for public light LX inside stops trigger output voltage, the normally opened contact of light-operated switch LX disconnects, the actuating coil outage of the first A.C. contactor 1KM, its main contact is disconnected, and the street lamp that the main contact of the first A.C. contactor 1KM is controlled extinguishes.
If light-operated switch LX goes wrong or the operational administrative personnel need to open or close street lamp, available operate in manual mode temporarily.In manual mode, at first the input of change over switch ST 1 is switched to the second output 3, then clicks normally open push button switch SA.Now, the actuating coil of on-delay relay K T makes time delay break contact KT-1 closure, enters the delay working state.The actuating coil of the first A.C. contactor 1KM and the second A.C. contactor 2KM all is switched on, and two A.C. contactor actions, connect its main contact, after the street lamp energising under main contact control, lights.The auxiliary contact 1KM-2 of the first A.C. contactor 1KM also is switched on, and makes the control relay group keep conducting.After the prior delay time of setting of time-delay relay KT has arrived, time delay break contact KT-1 automatic disconnection, the actuating coil outage of the second A.C. contactor 2KM, disconnect its main contact, and the street lamp that the main contact of the second A.C. contactor is controlled extinguishes.At any time, as needed closing control relay group, only need click normally closed push button switch TA, the power down of control relay group, all street lamps cut out.
The time delay of time-delay relay KT can be followed according to street lamp function and purposes and artificially set opening time, generally with 4~7 hours, is advisable.
The utility model has changed the method for controlling street lamps of common while opening and closing, both reached and opened and closed automatically street lamp according to ambient light illumination, again can setting-up time, realize the on purpose function of closed portion street lamp, the all right interim opening and closing street lamp of manual operation, made up the deficiencies in the prior art.Use the utility model to be conducive to the conservation of power resource.
