A working method of an adaptive protection switch cabinet comprises the following steps:
step S1, mounting components, namely selecting the mounting positions of the components according to the heating conditions of the components, mounting the components in the first cabinet body 11 with smaller heating value, mounting the components in the second cabinet body 12 with medium heating value and mounting the components in the third cabinet body 13 with larger heating value, and electrically connecting the components;

step S3, shockproof, vibration amplitude is measured through the vibration monitor 7, and the control box 8 controls the electric push rod 54 to extend or shorten: if the vibration amplitude is increased, the electric push rod 54 is shortened; if the measured vibration amplitude decreases, the electric push rod 54 is extended.
In the step S2, if the temperature measurement data of the infrared thermometer 6 indicates that the temperature of the component in a certain cabinet exceeds the set temperature threshold, and the temperature of the component exceeds the set time threshold for the ordinary heat dissipation time and does not drop, the control box 8 controls the semiconductor heat sink correspondingly connected to the component to start, so as to locally cool the component.
In the embodiment of the application, the working principle of the self-adaptive protection switch cabinet and the working method thereof is as follows: the mounting area of the components is selected according to the heating condition, and the heat dissipation effects in different cabinets can be adjusted by controlling the opening of the electric control air volume adjusting valve, so that the diversity of the heating condition of the components during operation is adapted; meanwhile, if a scene with insufficient air cooling heat dissipation capacity is met under an extreme condition, the semiconductor refrigerating sheet rapidly cools the components, and the overall heat dissipation effect of the switch cabinet is improved.
In the embodiment of the application, the sliding power connection device controls the on-off of the electromagnet, when the metal contact contacts with the conductive plate, the electromagnet is electrified, repulsion force is formed between the electromagnet and the magnet block to push the mounting plate to move upwards, and meanwhile, the reset spring obtains elastic potential energy; when the metal contact is separated from the current conducting plate, the electromagnet is powered off, the repulsive force between the electromagnet and the magnetite disappears and is converted into attractive force of the magnet block to the iron core of the power-off electromagnet, the elastic potential energy of the reset spring is released, the mounting plate is rapidly pushed to move downwards, and dust or impurities on the filter sheet are still stopped in the original position by inertia and are separated from the filter sheet. Along with the reciprocating motion of the first limit switch and the second limit switch control slide block, the electromagnet also forms a power-on-power-off-power-on periodic state, and the mounting plate also periodically and automatically cleans ash.
Through adjusting shockproof mechanism, can deal with the operational environment that cubical switchboard body vibration amplitude is different: if the vibration amplitude of the switch cabinet body is larger, the electric push rod is shortened, the tightening degree of a vibration-proof spring in the vibration absorber is weakened, the vibration-proof effect is improved, the vibration of the switch cabinet body is counteracted, and components in the switch cabinet body are protected; if the vibration amplitude of the switch cabinet body is larger, the electric push rod extends, the tightening degree of a vibration-proof spring in the vibrator is enhanced, the vibration-proof effect is reduced, and the stability of the switch cabinet body is improved; in addition, the balancing weight reduces the center of gravity of the switch cabinet body and improves the stability of the switch cabinet body.
