It can not only protect and monitor the transformer, but also perform fault diagnosis, thereby protecting the safety and normal operation of the transformer to the greatest extent. However, there are still some shortcomings in the existing transformer protection cabinet.

[0003] First, the transformer protection cabinet will generate a lot of heat when it is running, so it is necessary to install an exhaust fan on the cabinet to dissipate heat. The exhaust fan will fail when it runs for a long time. If the workers cannot find and repair it in the first time, it will easily cause the temperature inside the cabinet to rise and damage the internal parts.

[0004] Secondly, since the ground is not absolutely level, the cabinet is prone to shaking after installation. Although screws are now installed on the upper ends of the feet to adjust the height of the feet, workers still have difficulty turning the feet under the pressure of the cabinet's gravity.

[0043] The connecting seat 9 has a front end surface provided with a card slot, and the connecting seat 9 is fixedly mounted on the outer end surface of the left end side plate of the cabinet 1 , and the connecting seat 9 is located between the power supply component 7 and the alarm 8 .

[0044] Among them, the lower end surface of the support column 2 is provided with a connecting groove 201, and the inner end surface of the connecting groove 201 is provided with a thread. A connecting screw 301 is fixedly installed at the middle position of the upper end surface of the fixing block 3, and the connecting screw 301 is threadedly connected to the inside of the connecting groove 201. Four fixing tubes 303 are fixedly installed on the outer end surface of the fixing block 3. The four fixing tubes 303 are arranged in a ring-shaped structure. In use, the connecting screw 301 at the upper end of the fixing block 3 is threadedly connected to the connecting groove 201 at the lower end of the support column 2. When workers are installing the cabinet 1, some of the ground is uneven, so The four pads 302 are not on the same horizontal plane. At this time, the worker can rotate the fixing block 3 to adjust the position of the connecting screw 301 inside the connecting groove 201, so as to adjust the upper and lower height positions of the pads 302 to ensure that the cabinet 1 will not shake after installation.

[0047] By adopting the above scheme, the technical effect brought about is: when the exhaust fan 1021 is operating normally, the wind shield 5 drives the pull-down plate 501 to move outward, and at this time the conductive plate 5011 is detached from the connecting seat 9 inside the connecting seat 9, and a closed circuit cannot be formed between the power supply component 7 and the alarm 8. At this time, the alarm 8 will not alarm, and after the exhaust fan 1021 fails, the wind shield 5 will move toward the exhaust fan 1021, and at this time the conductive plate 5011 will be inserted into the card slot inside the connecting seat 9, and then the left and right ends of the conductive plate 5011 will fit together with the two conductive blocks 901, and at this time a closed circuit is formed between the power supply component 7, the first wire 701, the alarm 8, the second wire 702 and the third wire 801, and the alarm 8 will sound an alarm when powered on, reminding the workers that the exhaust fan 1021 has failed and stopped running, so that the workers can inspect and maintain the exhaust fan 1021 in time.

[0048] The specific usage and function of this embodiment are as follows:

[0049] In the present invention, the connecting screw 301 at the upper end of the fixing block 3 is threadedly connected to the connecting groove 201 at the lower end of the supporting column 2. When workers are installing the cabinet 1, some of the ground is uneven, so that the four pads 302 are not on the same horizontal plane. At this time, the worker can rotate the fixing block 3 to adjust the position of the connecting screw 301 inside the connecting groove 201, so as to adjust the upper and lower height positions of the pads 302 to ensure that the cabinet 1 will not shake after installation. The outer end surface of the fixing block 3 is also equipped with four fixing cylinders 303. When the worker rotates the fixing block 3 When the exhaust fan 1021 is operating normally, the wind blown out by the exhaust fan 1021 will blow toward the wind shield 5. Since the force-bearing area of ​​the wind shield 5 is large, the wind shield 5 will move outward, and the pull rod 601 will also move outward with the wind shield 5. At this time, the compression spring 603 outside the pull rod 601 is compressed to maintain a dynamic balance with the blowing force on the wind shield 5. When the exhaust fan 1021 fails, the wind blown out by the exhaust fan 1021 will blow toward the wind shield 5. Afterwards, the blowing force on the wind shield 5 disappears, and under the action of the elastic force of the compression spring 603, the pull rod 601 will move inward, and the baffle 602 will move to the innermost position of the connecting tube 4. At this time, the conductive plate 5011 on the surface of the pull-down plate 501 is inserted into the card slot inside the connecting seat 9. When the exhaust fan 1021 is operating normally, the wind shield 5 drives the pull-down plate 501 to move outward. At this time, the conductive plate 5011 is detached from the connecting seat 9 inside the connecting seat 9, and a closed circuit cannot be formed between the power supply component 7 and the alarm 8. At this time, the alarm 8 will not sound, and the exhaust fan 1021 will not sound. After fan 1021 fails, the wind shield 5 will move toward the direction of exhaust fan 1021. At this time, the conductive plate 5011 will be inserted into the slot inside the connecting seat 9, and then the left and right ends of the conductive plate 5011 will fit together with the two conductive blocks 901. At this time, a closed circuit is formed between the power supply component 7, the first wire 701, the alarm 8, the second wire 702 and the third wire 801. The alarm 8 will sound an alarm when powered on, reminding the workers that the exhaust fan 1021 has failed and stopped running, so that the workers can inspect and maintain the exhaust fan 1021 in time.
