Abstract
The utility model discloses a heat dissipation mechanism of a cabinet type transformer. The heat dissipation mechanism comprises a cabinet body and a transformer body, wherein a no-power fan is arranged at the top of the cabinet body, a wind inlet is formed in a lower part of the cabinet body, and an induced draft fan is arranged at the lower part of the cabinet body; a temperature monitoring and controlling mechanism which is arranged in the cabinet body comprises a microprocessor, a temperature sensor which is arranged on the transformer body, and an electromagnetic switch which is arranged on a power circuit of the induced draft fan. Through the adoption of the mechanism, the heat dissipation conditions of the transformer can be effectively improved, so that the transformer is well protected, the reliable operation of the transformer is ensured, and the frequency and the time of stopping supplying electric power are greatly reduced. The mechanism is simple in structure, low in investment, low in operation cost and convenient to use; the mechanism can automatically operate for a long time, without attending; the mechanism has good benefits and better practical and popularized values.
Description
Technical field
The utility model relates to electrical equipment technical field, relates in particular to a kind of cabinet type transformer cooling mechanism.
Background technology
Cabinet type transformer is hermetically sealed with it, compact conformation, all insulation, good looking appearance, volume are little, need not power distribution room, can directly be placed in indoor or outdoors, can ensure personal safety reliably, be power supply facilities, can decorate again the advantages such as environment and be used widely, progressively replace traditional transformer.But because it is totally-enclosed, volume is little and cause radiating condition poor, moreover many installation and operations in the open, in addition mostly there is the unbalanced operation conditions of load, especially at torridity summer, be worth again peak of power consumption, often because machine heating has to stop transport, after temperature lowers, restart, user has discontented more to this again, even causes transformer damage accident.
Utility model content
The purpose of this utility model is to overcome defect of the prior art, and a kind of radiating condition that can effectively improve transformer is provided, and reduces equipment fault, guarantees the cabinet type transformer cooling mechanism of the reliability service of transformer.
The technical scheme taked is for achieving the above object: a kind of cabinet type transformer cooling mechanism, comprise cabinet and transformer body, and described cabinet top arranges unpowered fan, and bottom arranges air inlet.
Described cabinet bottom arranges induced draft fan.
Set temperature Monitoring and Controlling mechanism in described cabinet, this temperature monitoring controlling organization comprises microprocessor, is arranged on the temperature sensor on described transformer body and is arranged on the electromagnetic switch on described fan power circuit.
Described air inlet arranges shutter, and air inlet inner side arranges filter.
Described unpowered fan arranges protective cover.
Cabinet type transformer cooling mechanism of the present utility model; accelerate the cross-ventilation speed in cabinet by unpowered fan and induced draft fan two-stage; can effectively improve the radiating condition of transformer; and make thus transformer obtain good protection; guarantee the reliability service of transformer, greatly reduce stopping for the frequency and time of electric power.The utility model is simple in structure, small investment, and operating cost is low, easy to use, can automatically move for a long time, exempts from nurse, profitable, has good practical and popularizing value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, cabinet type transformer cooling mechanism of the present utility model, comprises cabinet 1 and transformer body 2, and described cabinet 1 top arranges unpowered fan 8, and bottom arranges air inlet 4, forms the cross-ventilation structure in cabinet 1 by unpowered fan 8 and air inlet 4.Described air inlet 4 arranges shutter 5, can prevent entering of animal, bird, prevent simultaneously rainwater float into; Air inlet 4 inner sides arrange window type filter 6, for preventing entering of insect.Described cabinet 1 bottom arranges induced draft fan 3, for increasing the convection velocity of cabinet 1 interior air, further improves the radiating effect of transformer.The interior set temperature Monitoring and Controlling of described cabinet 1 mechanism, this temperature monitoring controlling organization comprises microprocessor 10, be arranged on the temperature sensor 9 on described transformer body 2 and be arranged on the electromagnetic switch (not shown) on the power circuit of described induced draft fan 3.Described unpowered fan 8 also can arrange a protective cover 7, neither affects the discharge of air, can protect again unpowered fan 8 not to be damaged, and prevents that rainwater, foreign material from falling into cabinet 1 by exhaust outlet simultaneously.
Cabinet type transformer cooling mechanism of the present utility model is in the time that transformer moves, by forming the cross-ventilation structure in cabinet by unpowered fan 8 and air inlet 4, can accelerate the cross-ventilation in cabinet 1, make the air that temperature is lower constantly enter cabinet 1, the high-temperature gas in cabinet 1 is discharged by unpowered fan 8.When only depending on unpowered fan 8 to be not enough to the too high temperature rise of eliminating transformer, when transformer temperature can reach setup control temperature, feed back by temperature sensor 9, by microprocessor 10 transmitted signals, start induced draft fan 3, further strengthen the cross-ventilation speed in cabinet 1, reach the object of improving transformer radiating effect.Below transformer temperature is reduced to setup control temperature time, control by microprocessor 10 operation that stops induced draft fan 3, be beneficial to the saving of energy consumption.Thus, make transformer obtain good protection, guarantee the reliability service of transformer, greatly reduce stopping for the frequency and time of electric power.
