The first conductive layer 107 and the second conductive layer 108 are used to detect the load current of the electrical parts inside the outer shell cabinet 101, and can also drive the air outside the outer shell cabinet 101 to flow inside. Multiple rows of electrical mounting racks are arranged inside the outer shell cabinet 101, and a heat receiving plate 103 is fixed in the middle of the inner wall of the outer shell cabinet 101, and a resistor rod 102 is arranged through the heat receiving plate 103.

The transmission shaft 109 and the central driving gear 119 are connected by a transmission belt 124. A bottom protective shell 129 is provided on the outside of the separation chamber 110. The bottom protective shell 129 is fixed to the bottom of the outer shell cabinet 101, and a plurality of ventilation holes are provided on the bottom protective shell 129. A door panel 130 is also movably mounted on the outer shell cabinet 101.

[0022] The working principle of an intelligent monitoring system for electrical equipment disclosed in the present invention is as follows: the required electrical components are installed in an outer casing cabinet 101. As time and the surrounding environment change, the temperature inside the outer casing cabinet 101 may increase. At this time, the increased temperature will be transferred to the heat-receiving plate 103. The high temperature of the electrical components will heat the air. The air will heat the heat-receiving plate 103. The heat-receiving plate 103 transfers the temperature to the resistor rod 102. The increase in the temperature of the resistor rod 102 will cause its own resistance value to change. The change in the resistance value of the resistor rod 102 is used to control the speed of the output shaft of the drive motor 115. The rotation of the output shaft of the drive motor 115 drives the drive disk 116 to rotate. The rotation of the drive disk 116 will drive the center drive gear 119 to rotate through the planetary gear 118 (when the rotation of the limiting toothed plate 120 is restricted). The rotation of the center drive gear 119 will be transmitted through the transmission Belt 124 drives the transmission shaft 109 to rotate, and the rotation of the transmission shaft 109 will drive the two fan blades 106 to rotate. When the two fan blades 106 rotate, they will drive the external air into the separation chamber 110 through the air suction nozzle 111. Since the air suction nozzle 111 is set tangentially along the separation chamber 110, the air entering the separation chamber 110 will rotate at this time. If there are dust particles in the air, they will also rotate with the air. During the rotation, the dust particles will be affected by the centrifugal force and rotate on the inner wall of the separation chamber 110, while the lighter air will enter the diversion channel 105 through the partition pipe 112, and then enter the outer shell cabinet 101 through the air inlet pipe 104, and then be discharged vertically upward through the exhaust port 114. At this time, the hot air inside the outer shell cabinet 101 can be taken away, thereby achieving the purpose of heat dissipation for the electrical components inside the outer shell cabinet 101.

[0023] The rotation of the fan blades 106 will drive the first conductive layer 107 and the second conductive layer 108 to rotate. The rotation of the first conductive layer 107 and the second conductive layer 108 will cut the magnetic field generated by the working process of the cables inside the outer casing cabinet 101, and then generate an induced electromotive force at both ends of the first conductive layer 107 and the second conductive layer 108. Since the rotation speed of the fan blades 106 is known, the strength of the magnetic field can be known. The strength of the magnetic field depends on the size of the load current of the cables inside the outer casing cabinet 101, thereby achieving the purpose of real-time detection of the load current inside the outer casing cabinet 101, and at the same time can drive air flow. In order to facilitate the display of the distance between the first conductive layer 107 and the second conductive layer 108 in the figure, the distance between them is relatively large. In fact, the electromotive force at both ends of the first conductive layer 107 and the second conductive layer 108 that are not connected is detected. If the complex temperature inside the outer shell cabinet 101 is too high, the auxiliary drive motor 123 is started, and the output shaft of the auxiliary drive motor 123 is started (a one-way transmission mechanism is arranged between the output shaft of the auxiliary drive motor 123 and the limiting gear 121, such as a gearbox with a large transmission ratio, or a worm gear mechanism), and the output shaft of the auxiliary drive motor 123 drives the limiting gear 121 to rotate, and the limiting gear 121 drives the limiting toothed disc 120 to rotate. The rotation of the limiting toothed disc 120 will change the transmission ratio between the drive motor 115 and the transmission shaft 109, thereby increasing the rotation speed of the fan blades 106, and further increasing the air flow rate. At the same time, the temperature inside the outer shell cabinet 101 will be transferred to the heated plate 125, thereby heating the electronic fluoride liquid inside the heated plate 125. The heated plate 125 and the heat sink 126 are set at a negative pressure. The electronic incubator inside the heated plate 125 will evaporate after being heated, and the evaporated gas will flow to the heat sink 126. Since air flows through the heat sink 126, the heat sink 126 will be cooled. At this time, the temperature of the heat sink 126 will be lower than the boiling point of the electronic fluoride liquid. At this time, the gaseous electronic fluoride liquid will condense inside the heat sink 126, thereby becoming liquid, and then fall back into the heated plate 125 under the action of gravity.
