As shown in Fig. 9, a kind of alarm system of the radiating electrical cabinet of electrical automation control, the alarm system comprises signal acquisition module, signal transmission module and display alarm module;

The working principle and use process of the present invention: in the actual application process of the heat dissipation electric cabinet controlled by the electric automation, firstly, when the electric cabinet body 1 is running, the first heat dissipation fan 602 and the second heat dissipation fan 603 inside it are used to control the heat dissipation. The internal electrical components are heat-dissipated. At this time, the heat airflow blown out by the first heat dissipation fan 602 and the second heat dissipation fan 603 can be collected by the heat-collecting cone bucket 606, and can be improved by the heat-conducting metal strip 607 during collection. The collection effect of the heat-collecting conical bucket 606 on the thermal air flow is that the heat-collecting conical bucket 606 transports the thermal airflow to the heat-collecting runner 608 after the thermal airflow is collected;

And when the thermal air flow enters the heat collecting runner 608, and when the temperature inside the electrical cabinet body 1 is at a normal temperature, the thermal air flow will be directly introduced into the heat dissipation runner 621 after staying inside the heat collecting runner 608, Since the inner side of the heat dissipation flow channel 621 is provided with a gas barrier 622 and a spoiler 623, the gas barrier 622 and the spoiler 623 can delay the discharge time of the heat flow, so that the heat flow can stay longer in the heat collection flow channel 608 At last, the thermal air flow is discharged from the inside of the electrical cabinet body 1 by the cooling bucket 625 at the end of the cooling channel 621;

And when the heat carried inside the thermal airflow is too high, that is, when the temperature inside the electrical cabinet body 1 is too high, the thermal airflow will directly act on the heat-absorbing and expanding silica gel sheets 612 on both sides of the heat-collecting runner 608, and absorb heat. After the heat-expandable silica gel sheet 612 is affected by the high-temperature thermal air flow, due to the principle of its own thermal expansion, the heat-absorbing expansion silica gel sheet 612 will expand to the outside of the heat-collecting runner 608. The protruding head 613 will then be squeezed by the heat-absorbing and expanding silica gel sheet 612, so the movable plate 610 will slide along the guide slider 611 at the bottom along the fixed bracket 609, and when the movable plate 610 slides, its The moving rod 614 at one end will drive the extruding rod 616 and the moving contact 618 to move together, and at the same time the support spring 617 shrinks, and when the moving contact 618 moves to contact with the contact switch 620, the contact switch 620 operates at this time, and passes Contact the switch 620 to start the auxiliary cooling fan 605, and after the first heat dissipation fan 602, the second heat dissipation fan 603 and the auxiliary cooling fan 605 are all turned on, the wind force produced by the thermal air flow inside the heat dissipation flow channel 621 is compared with that of the first heat dissipation fan 602. When the first radiating fan 602 and the second radiating fan 603 are in operation, the airflow will generate more wind, so the gas barrier 622 and the spoiler 623 inside the radiating channel 621 will be deflected by the movable shaft 624 at its end to In this way, the diameter of the heat dissipation flow channel 621 can be quickly opened, so as to facilitate the rapid discharge of the heat flow and realize rapid heat dissipation. Through the above heat dissipation method, the basis of heat dissipation in the first heat dissipation fan 602 and the second heat dissipation fan 603 is realized. In combination with timely opening of the auxiliary cooling fan 605 to strengthen the heat dissipation effect inside the electrical cabinet body 1, so that the electrical cabinet body 1 can self-regulate and respond in time when dealing with sudden high temperature conditions, and through the above methods to achieve Automatic regulation, so that the electrical cabinet body 1 will not cause excessive energy consumption during normal operation, thereby avoiding energy waste;

In addition, after the moving contact 618 touches the contact switch 620, since the warning light 4 is connected to the contact switch 620, the warning light 4 will also run in time, so as to remind the staff in time, and then facilitate the staff to timely check the electrical cabinet body. 1 for maintenance, and after the auxiliary cooling fan 605 has been running for a period of time, and when the temperature inside the electrical cabinet body 1 tends to normal temperature, the thermal air flow inside the heat collecting runner 608 cannot expand the heat-absorbing expansion silica gel sheet 612, Therefore, the heat-absorbing expansion silicone sheet 612 will return to its original shape, and the deformation of the support spring 617 will be used to drive the extrusion rod 616 and the moving contact 618 to reset in time, so as to disconnect the contact switch 620 and make the auxiliary cooling Fan 605 stops running, so that the electrical cabinet body 1 runs at a normal temperature;

During the heat dissipation process of the first heat dissipation fan 602 and the second heat dissipation fan 603, the air intake slot 1001 on the side of the base 5 facilitates the timely delivery of the external cooling airflow to the inside of the electrical cabinet body 1, and at the same time, the external airflow enters to the bottom When inside the seat 5, the dust and sundries mixed in the external airflow can be blocked and filtered through the dirt-blocking screen 1004 on the outside of the air intake slot 1001, thereby preventing dust and sundries from entering the electrical cabinet body 1. Its internal electrical components cause pollution and damage;

At the same time, after the airflow enters the base 5, the desiccant filled inside the disassembly box 1102 can absorb the moisture and moisture in the airflow, thereby preventing the moisture and moisture from liquefying inside the electrical cabinet body 1, so that the electrical appliances damage to components;
