Abstract
The utility model discloses a frequency-converting energy-saving system for a wind cabinet. The frequency-converting energy-saving system for the wind cabinet includes a temperature transmitter, and a three-phase AC power input terminal, a circuit breaker, a fuse, a current transformer, a frequency converter and a servo permanent-magnet synchronous motor used for the wind cabinet sequentially connected together. The temperature transmitter is connected to a control signal input terminal of the frequency converter. A wire outlet and a wire inlet of the frequency converter are both equipped with magnetic rings. The utility model overcomes a technical shortcoming of large energy loss of the air-condition wind cabinet in the prior art and provides the energy-saving frequency-converting energy-saving system for the wind cabinet.
Description
Technical field
The utility model belongs to the air-conditioning refrigeration system technical field, is specifically related to a kind of wind cabinet energy-saving and frequency-variable system.
Background technology
Conventional large-size water-cooling cabinet-type air conditioner generally all is designed to constant air volume system, wind cabinet centrifugal blower is usually in oepration at full load, usually the design day oepration at full load time quite few, load between with cold-room reduce after, motor can be according to the adjustment running speed, and it is bigger to consume energy.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of wind cabinet energy-saving and frequency-variable system that makes that the large-size water-cooling cabinet-type air conditioner is more energy-conservation.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
Wind cabinet energy-saving and frequency-variable system, comprise temperature transmitter and the three-phase alternating-current supply input, circuit breaker, fuse, current transformer, frequency converter, the servo permagnetic synchronous motor of wind cabinet that connect successively, described temperature transmitter is connected the control signal input of described frequency converter, and the incoming line of described frequency converter and line outlet all are equipped with magnet ring.
When the utility model uses, temperature transmitter is installed in wind cabinet return air inlet and detects return air temperature, utilize the operation of the signal controlling frequency converter of temperature transmitter, after wind cabinet motor adopts variable frequency control, original constant air volume system can change variable air volume system into, power frequency operation when return air temperature is high, converting operation when return air temperature is low is saved a large amount of electric energy.
The utility model is when starting, and it is soft start that frequency converter can be set, and can reduce the impact to the blower fan mechanical part, prolongs the useful life of equipment.
Install magnet ring additional and not only reduced the high-frequency harmonic that produced by frequency converter to the influence of instrument and equipment, and saved cost again greatly.The capacity difference of frequency converter, input reactance device and the cost price of corresponding increase is different for this reason, frequency inverter capacity is more big, and the cost that adopts the method for high frequency magnet ring to save is more low.After more than frequency inverter capacity is greater than 75KW, adopt the high frequency magnet ring to reduce the cost of humorous wave method, only account for and adopt the input reactance device to reduce 1/10th of humorous wave method cost, in addition lower.And after more than frequency inverter capacity is greater than 185KW, adopt the high frequency magnet ring to reduce the cost of humorous wave method, and only account for and adopt the input reactance device to reduce 1/20th of humorous wave method cost, in addition lower.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model wind cabinet energy-saving and frequency-variable system, comprise transmitter and the three-phase alternating-current supply input, circuit breaker Q F, fuse FU, current transformer CT, frequency converter, the servo permagnetic synchronous motor of wind cabinet that connect successively, described transmitter is connected the control signal input of described frequency converter, and the incoming line of described frequency converter and line outlet all are equipped with magnet ring K.Transmitter is temperature transmitter, can adopt model HB.55-SWP201.
Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection range of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
