Preferably, a sealing ring is mounted on the first rotating shaft 26 in the second through hole 82 to prevent the fourth cavity 94 from being directly exposed to air.

A using method of a transformer comprises the following specific steps:

firstly, when the transformer works normally and the temperature sensor 24 is not triggered by the internal temperature of the transformer, the first motor 16 is not electrified, the first electromagnet 49 is not electrified to cause the sealing block 52 to slide upwards and separate the sixth cavity 96 from the first cavity 91, the second sliding block 21 is in a normal position and does not trigger the first trigger sensor 19, the first transmission rod 31 is positioned in the third cavity 93 and is clamped by the clamping block 36, the baffle plate 27 is positioned in the fourth through hole 84 and triggers the second trigger sensor 28, the first sliding block 13 and the universal wheel 14 are completely positioned in the second cavity 92 at the moment, and calcium chloride particles capable of absorbing water are placed in the fourth cavity 94 positioned on the lower side of the inclined fixing block 42;

secondly, when the invention is required to move, the baffle 27 is opened backwards, the first transmission rod 31 is swung forwards and backwards, when the first transmission rod 31 swings forwards, the sealing block 34 slides upwards through the second transmission rod 33, at the same time, the through hole at the upper side of the flow channel 35 is positioned in the cavity 93 so that water in the cavity 93 can flow into the through hole 85 at the lower side of the sealing block 34 through the flow channel 35, when the first transmission rod 31 swings backwards, the sealing block 34 slides downwards through the second transmission rod 33, at the same time, the flow channel 35 is completely positioned in the through hole 85 at the fifth side, water in the through hole 85 at the fifth side is pressed into the cavity 92 at the upper side of the first sliding block 13 through the check valve 29 until the first sliding block 13 slides downwards and abuts against the limiting plate 15, at the same time, the universal wheel 14 is positioned at the lower side of the shell 11 and can drive the invention to move, when the invention is finished, the first transmission rod 31 is placed in the cavity 93 again and is held by, at the moment, the third cavity 93 is sealed through the baffle 27, when the baffle 27 closes the third cavity 93 and triggers the second trigger type sensor 28, the second trigger type sensor 28 releases a signal to open the ball valve 30, and at the moment, high-pressure water in the second cavity 92 flows into the fourth cavity 94 again through the sixth through hole 86 until the universal wheel 14 is completely positioned in the second cavity 92, so that the displacement of the universal wheel is completed;

thirdly, when the temperature sensor 24 is triggered due to overhigh temperature caused by higher working load of the transformer, the temperature sensor 24 releases a signal to enable the first motor 16 to be electrified and the third electromagnet 58 to be powered off, the first rotating shaft 26 to rotate when the first motor 16 is powered on, the third sliding block 62 outwards slides and abuts against the rectangular limiting block 60 when the third electromagnet 58 is powered off, so that the first rotating shaft 26 can drive the first bevel gear 37 to rotate through the first intelligent driving ring 110, the first bevel gear 37 drives the second rotating shaft 38 to rotate through the second bevel gear 41 which is meshed with the first bevel gear, and the fan blades 40 rotate to enable wind to enter the first cavity 91 and be discharged through the third through hole 83 for heat dissipation;

fourthly, when the working environment of the transformer is moist and reaches the threshold value of the humidity sensor 25, the humidity sensor 25 releases a signal to enable the first motor 16 to be electrified, the second electromagnet 58 to be powered off, the first electromagnet 49 to be electrified, the first rotating shaft 26 rotates when the first motor 16 is electrified, the first rotating shaft 26 can drive the third rotating shaft 43 to rotate through the second intelligent driving ring 111 when the second electromagnet 58 is powered off, the threaded disc 44 on the third rotating shaft 43 rotates and drives calcium chloride particles in the fourth cavity 94 to move upwards when the third rotating shaft 43 rotates, the calcium chloride particles enter the sixth cavity 96 through the ninth through hole 89 when the calcium chloride particles move to the upper side of the inclined plane limiting block 42, the first electromagnet 49 is electrified and attracts the sealing block 52 to enable the sixth cavity 96 to be communicated with the first cavity 91, the calcium chloride particles in the sixth cavity 96 can absorb water, and water solution formed by the water absorbed by the calcium chloride can enter the water receiving cavity 97 through the water drainage hole 54 In the box 53, when the humidity sensor 25 senses that the humidity in the first cavity 91 reaches the standard, the second electromagnet 57 is powered off and the first electromagnet 49 is powered off, at the moment, the sealing block 52 slides upwards and separates the sixth cavity 61 from the first cavity 91, calcium chloride particles in the fourth cavity 94 are prevented from continuously absorbing water, and consumable materials are reduced;

fifthly, when a line connected with the dry type transformer 23 in the first cavity 91 catches fire, the temperature in the first cavity 91 rises, at the moment, the heat dissipation device 102 automatically starts to work, when the temperature in the first cavity 91 enables mercury in the fifth cavity 95 to expand through the heat conduction layer 20 and enables the second sliding block 21 to slide upwards and trigger the first trigger type sensor 19, the first trigger type sensor 19 releases a signal to enable the dry type transformer to be powered off and enable the warning lamp 12 to work, due to the fact that the dry type transformer is adopted, after the power is off, the fire in the first cavity 91 of the dry type transformer is automatically extinguished, and the warning lamp 12 serves to prompt a worker to overhaul the dry type transformer.
