As shown in fig. 1-7, the utility model provides a moisture-proof and dust-proof dry-type transformer, which comprises an outer box 1, a winding 2 and an external component 3, and is characterized in that the outer box 1 is divided into a first cavity 11 and a second cavity 12, the winding 2 is located in the first cavity 11, and the external component 3 is located in the second cavity 12; the outer box body 1 is further provided with an automatic adjusting device 4 and a ventilation assembly 6, the automatic adjusting device 4 comprises a processor 42 located in the second cavity 12 and a sensor located in the first cavity 11, the ventilation assembly 6 is connected with the processor 42 and comprises an exhaust fan 61 which is detachably and fixedly arranged on one side surface of the length direction of the first cavity 11 and a filtering air intake assembly 62 which is arranged on the other corresponding side surface, the filtering air intake assembly 62 comprises a plurality of stacked and detachable dustproof filter nets 621, a moistureproof filter net 622 and a driving unit 63 which is fixedly arranged on the first cavity 11, the moistureproof filter net 622 is divided into a fixed net 6222 which is fixedly arranged and a movable net 6221 which is provided with a slide rail and movably arranged relative to the fixed net 6222, the movable net 6221 and the fixed net 6222 of the moistureproof filter net 622 are arranged in a staggered manner, and the movable net 6221 is fixedly connected with the driving unit 63, and the movable net 6221 can be driven by the driving unit 63 to move along the sliding rail to the overlapping position of the fixed net 6222, so as to form a ventilation opening 623 free of the filtering of the moisture-proof net.

As a further arrangement of the above solution, the driving unit 63 may adopt an air cylinder or a servo motor as a power source.

As a further arrangement of the above scheme, the outer box 1 is further provided with a plurality of retractable universal wheels.

As a further configuration of the above solution, the sensor includes a temperature and humidity sensor.

As a further configuration of the above solution, the processor 42 is located in the second cavity 12 and includes a touch display screen 41.

As a further arrangement of the above solution, the processor 42 further includes a danger alarm device.

As a further arrangement of the above scheme, an outer frame is further provided for installation and fixation in addition to the movable net 6221 and the fixed net 6222 of the moisture-proof filter net 622.

As a further arrangement of the above scheme, the dustproof filter screen 621 and the moisture-proof filter screen 622 are mounted with the filtering air intake assembly 62 in a clamping manner.

The transformer of this scheme is provided with dual cavity, and transformer work main part is located first cavity 11, and first cavity 11 only leaves one-way air exit and one-way scavenge port for the confined space.

When an operator installs the transformer, the transformer can be moved by putting down the universal wheels, and the universal wheels are retracted after the transformer reaches a specified position to put down the fixed foot stool so as to realize fixation and positioning; after the transformer is placed, the wire can be connected into the transformer only by opening the movable door on the second cavity 12.

Carry out normal operating condition at the transformer, automatic regulating apparatus 4 operation this moment, exhaust fan 61 low-power lasts the worker and takes a breath as in first cavity 11, the temperature that sets up in first cavity 11, the centralized calculation in humidity transducer detected signal output to automatic regulating apparatus 4's the treater 42, when the temperature, when the skew preset value of humidity, automatic regulating apparatus 4 control exhaust fan 61 works with higher speed, discharge the air in first cavity 11, outside air gets into in first cavity 11 through filtering the multiple dampproofing dustproof filter screen of subassembly 62 that admits air simultaneously and filtering back, this scheme adopts the multilayer filter screen, from outer to interior in proper order range upon range of dustproof filter screen 621 and dampproofing filter screen 622, guarantee that the air of new entering does not influence the transformer as far as possible.

The dampproofing filter screen 621 of this scheme divide into activity net 6221 and fixed network 6222, the activity of the relative fixed network 6222 of activity net 6221 sets up, when the high temperature in first cavity 11, need accelerate exhaust fan 61 speed, improve air flow rate, realize the rapid exchange cooling of inside and outside air, nevertheless because of the existence of dampproofing filter screen 621, lead to the production of the not in time low pressure environment of sending of air inlet easily, therefore, reach a definite value after the rotational speed of exhaust fan 61, automatic regulating apparatus 4 need control drive unit 63 work, the activity net 6221 activity of the dampproofing filter screen 622 of drive is to overlapping with fixed network 6222, it avoids admitting air not enough and leads to inside production low pressure environment to let go, lead to the heat dissipation variation and lead to the accident. Because only under the too high condition of inside temperature, exhaust fan 61 just can accelerate for work is relieved to dampproofing filter screen 621, and inside temperature is higher than first cavity 11 ambient temperature far away this moment, so also need not worry the air condensation and the dampproofing problem in inside of unfiltered steam, only need keep dustproof can.

The transformer of this scheme, still automatically regulated humiture when guaranteeing dirt-proof, and nimble control filter screen, the atmospheric pressure environmental change of the outer box 1 inside of avoiding taking a breath fast and leading to is too big, and short-term maintenance only need open the filtration subassembly 62 that admits air and change dustproof filter screen 621 and dampproofing filter screen 622 and the cleaning of surface can.

The above description should not be considered as limiting the present invention, and any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included within the protection scope of the present invention.
