Description
Technical field:
The utility model relates to the reactive compensation system technical field, is specifically related to a kind of infrared radio control technology that is used for reactive compensation system.
Background technology:
So-called reactive power generally is exactly the power that power consumption equipment consumed of consumed power not.Such as in the capacitor incoming transport circuit, circuit will discharge and recharge capacitor, so just forms electric current; Capacitor stores electric energy during charging, capacitor is returned power supply to electric energy again during discharge, like this this power consumption equipment of capacitor consumed power not itself; Yet it but has power (power equals voltage and multiply by current strength), and though reactive power that Here it is is capacitor consumed power not; But because electric current is arranged; So meeting consumed power (electric wire all has resistance) on the power circuit, a kind of especially burden concerning the power transformer of power supply is because the capacity of transformer (power that it can provide) is limited; Reactive power can take the capacity of transformer, and normal power supply is restricted.Equally, an inductor incoming transport circuit, also can produce reactive power.But capacitor makes current phase leading, and inductor lags behind current phase, and their effect is just in time opposite, can cancel out each other.General power consumption equipment all is inductive, and like the motor in the factory, it can produce lagging reactive power, not only makes power line consumed power in vain, and the burden of the circuit that increases electric power takies the capacity of power transformer especially in vain, is very harmful.At this moment shunt capacitor on motor is cancelled out each other the effect of inductive load and capacitive load, and this has not just had the influence of reactive power concerning power circuit and transformer.Reactive power compensator is exactly supporting capacitor (being formed in parallel by many capacitors) frankly speaking, and it is by the automatic place in circuit of automatic control equipment, neither can undercompensation, can not compensate excessive yet.
Reactive power compensating controller has three kinds of sample modes, power factor type, reactive power type, reactive current type.Selecting that a kind of physics control mode in fact is exactly the selection to reactive power compensating controller.Controller is the command system of reactive power compensator, sampling, computing, sends the switching signal, and functions such as parameter setting, measurement, element protection are accomplished by compensating controller.Experienced for over ten years by discrete component that--process of a fast development of integrated circuit--single-chip microcomputer--dsp chip, its function is also perfect further.
Combination switch is the device that is used for control capacitance device switching.With the parallelly connected use of thyristor with relay tip, realize voltage zero-cross input and current over-zero excision by thyristor, come through continuous current by mechanical contacts, so just avoided the conduction loss problem of thyristor, shoving when also having avoided capacitor to drop into.Owing to not only used power electronic device but also used mechanical contacts, therefore be called combination switch.Combination switch drops into the characteristics of excising with current over-zero with its capacitor no-flashy-flow, has obtained to use widely.
And existing reactive compensation system is to adopt the wired connection mode; To each common fill switch, need slave controller to draw 2 control lines and receive on the control terminal of switch, divide fill switch then need connect 4 control lines to each; Under this mode, have the higher manual routing and the expense of cable.
The utility model content:
The purpose of the utility model provides a kind of infrared radio control technology that is used for reactive compensation system; It is with adopting the infrared radio connected mode between idle compensating control and the combination switch; Generally between 5-10M, transmission rate can reach 4Mbps to its communication distance the soonest, and communication media is that wavelength is the near infrared ray about 900 nanometers; And technology maturation, cost are low, the expense and the labour cost of having saved the electric wire auxiliary material greatly.
In order to solve the existing problem of background technology; The utility model is to adopt following skill scheme: it comprise idle compensating control 1, three-phase divide plerosis to run jointly to close 2, first three-phase altogether plerosis run jointly close 3 and second three-phase altogether plerosis run jointly and close 4, idle compensating control 1 through the infrared radio signal respectively with three-phase divide plerosis to run jointly to close 2, first three-phase altogether plerosis run jointly close 3 with second three-phase altogether plerosis run the infrared one of closing 4 one sides jointly and receive head and be connected.
The effect of described idle compensating control 1, the power factor of raising electrical network reduces the loss of supply transformer and outlet line in electric power system, improves power supplying efficiency, improves the power supply environment.Its concrete operation principle is: through to the voltage in the supply line; Electric current, reactive power and power factor etc. is carried out real-time follow-up, analyzes through microprocessor; Calculate reactive power and predefined numerical value compares; The compensation capacity that automatic selection can reach the The optimal compensation effect is controlled corresponding combination switch and is realized that shock-free input shunt capacitor improves the line power factor with this fast.
The effect of described combination switch: thoroughly solved the A.C. contactor switching and shoved greatly, contact easy-sintering and thyristor noncontacting switch energy consumption are big, and heating is big, produce the problem of harmonic wave; The assurance voltage zero-cross drops into, the current over-zero excision, and no surge, the contact is sintering not; Energy consumption is little, does not generate heat, and does not produce harmonic pollution; Realize the level and smooth of capacitor group, increased the service life, improved the quality of power supply.
The operation principle of the utility model: idle compensating control 1 output is sent the infrared communication signal through the 38khz infrarede emitting diode.Each combination switch all has an address toggle switch and the infrared one of 38khz to receive head.When idle compensating control 1 needed a certain road of switching combination switch, transmission earlier needed the address of the combination switch of control, sends corresponding switching signal then.Combination switch is received behind the address signal address check prior to itself, if address matches, then continues to receive the switching signal of back, then the switching of control capacitance device.If the address does not conform to, then no longer receive the switching signal of back, corresponding capacitor is not carried out switching yet.So just can send the switching that the infrared radio signal is controlled combination switch through infrarede emitting diode.
The utility model is with adopting the infrared radio connected mode between idle compensating control and the combination switch; Its communication distance is generally between 5-10M; Transmission rate can reach 4Mbps the soonest; Communication media is that wavelength is the near infrared ray about 900 nanometers, and technology maturation, cost are low, the expense and the labour cost of having saved the electric wire auxiliary material greatly.
