Abstract
The utility model relates to a soft starting controller for air conditioners, belonging to a soft starting controller for household air conditioners. The soft starting controller for air conditioners is composed of a rectification circuit, a delay circuit and a soft starting circuit. The soft starting circuit is connected in series with a return circuit which is composed of the output end of commercial power and a power input socket for air conditioners. The output end of commercial power is connected with the input end of the rectification circuit by a transformer. The output end of the rectification circuit is connected with the input end of the delay circuit whose output end is connected with the control end of the soft starting circuit. The utility model can limit starting current surge and can effectively avoid tripping operation, prevent a fuse from being burnt, prevent an electricity meter from being burnt and reduce fire accidents. The electric meter does not need to be changed and no power line needs to be arranged any longer when a household air conditioner is arranged.
Description
The utility model relates to a kind of air conditioner soft start-up controller, belongs to the domestic air conditioner soft start-up control device.
The starting current of existing domestic air conditioner is about 6 times of rated operational current, general refrigerating capacity at the domestic air conditioning starting current of 2-3 thousand kilocalories all more than 20 amperes, and air conditioner itself is not provided with the attachment device of preventing this startup surge, therefore, general family can not directly install and use air conditioner because of the supply lines footpath is thin, kilowatt-hour meter is less, and must draw power line in addition and change kilowatt-hour meter, for using air conditioner, the user makes troubles.
The purpose of this utility model is in order to overcome above-mentioned weak point of the prior art, and a kind of startup surge that can limit is provided, tripping operation that overload causes be can avoid again effectively, burn insurance, kilowatt-hour meter and or the air conditioner soft start controller of fire incident burnt.
The purpose of this utility model is achieved in that it comprises rectification circuit, delay circuit, soft starting circuit three parts, soft starting circuit is serially connected in the loop of civil power output and air conditioner power input socket formation, the civil power output also joins by the input of transformer and rectification circuit, the output of rectification circuit and the input of delay circuit join, and the output of delay circuit and the control end of soft starting circuit join.The utility model is after connecting civil power, at first by the current-limiting resistance step-down current limliting in the soft starting circuit, make air-conditioning begin soft start, the compressor starts low-speed running, meanwhile, rectification circuit provides working power for delay circuit, export control signal behind the delay circuit time-delay certain hour, control device in the starting soft starting circuit makes the current-limiting resistance short circuit, for compressor of air conditioner provides normal civil power.
The utility model compared with prior art, because the step-down current limliting of soft starting circuit and the time-delay of delay circuit power supply, avoided starting the appearance of surge current effectively, thereby tripping operation, burning insurance, burning ammeter even the breaking out of fire phenomenon of having avoided overload to cause, therefore, during the user installation air-conditioning, needn't change ammeter again, not need to draw in addition power line.
The explanation of accompanying drawing drawing:
Fig. 1 is a circuit block diagram of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment describes the utility model in detail below in conjunction with (accompanying drawing): the soft starting circuit in the present embodiment is made up of bidirectional triode thyristor BCR and current-limiting resistance R, is serially connected with after BCR and the R parallel connection in the loop of civil power output and air conditioner power input socket CZ formation; Delay circuit is by time base circuit 555, capacitor C
2, resistance R
1Form, resistance R is passed through in 555 3 pin output
2Join with the control end of bidirectional triode thyristor BCR; Rectification circuit is made up of rectifier bridge QL, and QL is by filter capacitor C
1Join with the input of delay circuit.The power switch of turning on the aircondition earlier when using this controller, after this controller power source K switch of closing then, the 220V electric main is given air condition power socket CZ power supply after current-limiting resistance R step-down current limliting, air-conditioning begins soft start, the compressor of air conditioner low cruise, meanwhile, after this controller power source K switch of closing, by transformer B and the rectification of rectifier bridge QL transformation, by capacitor C
1For time base circuit provides dc supply, at this moment, 2,6 pin of time base circuit 555 are high level, and 3 pin are output as low level, and bidirectional triode thyristor BCR is in closed condition, C
2Begin charging, after 3 seconds, C
2Charging finishes, and the output of 3 pin changes high level into, and this high level triggers the BCR bidirectional triode thyristor and makes it conducting, and current-limiting resistance R is by short circuit, and soft start finishes, and the 220V alternating current circuit is given air-conditioning socket CZ power supply through bidirectional triode thyristor, and compressor of air conditioner transfers normal operation to.
