[0016] A monitoring method for a switch circuit breaker monitoring device comprises the following steps: S1.

At this time, the elastic strip rebounds and drives the knocking ball to knock on the static contact and the moving contact, causing the static contact and the moving contact to vibrate, and the high-temperature resistant scraping strip to vibrate, thereby removing the soot and soot residue on the surface of the static contact and the moving contact through vibration.

[0019] 3. The rotation of the fan blades of the present invention generates air pressure in the boost chamber, which makes the air flow in the smoke pipe flow faster, increases the gas flow rate in the smoke pipe, and the smoke collecting nozzle gathers the smoke into the smoke pipe, and the smoke is discharged outward through the smoke pipe, avoiding blackening of components, improving conductivity and reducing failure rate.

[0020] 4.

[0021] 5. In the present invention, when the temperature of the static contact and the moving contact reaches the maximum value, the thermal expansion liquid further expands due to the heat, the lower pressure plate drives the displacement rod to continue to descend, the displacement rod presses down the top column, the top column drives the moving contact plate to descend, and the moving contact plate drives the moving contact to descend.

[0037] Example 2 refer to Figures 1 to 14The present invention provides a switch circuit breaker monitoring device. When the static contact 13 and the moving contact 14 are adhered, it is difficult to separate the static contact 13 and the moving contact 14. When the current is too large, the static contact 13 and the moving contact 14 may generate high temperature, which may easily cause the static contact 13 and the moving contact 14 to burn, resulting in soot and soot residue on the surface of the static contact 13 and the moving contact 14, affecting the conductivity of the static contact 13 and the moving contact 14, causing poor contact and causing fireworks. It is difficult to separate the static contact 13 and the moving contact 14 to cut off the power, which may easily cause safety accidents, and the smoke generated in the circuit breaker is difficult to discharge. The smoke exhaust efficiency of the smoke pipe 521 is slow, resulting in soot generated on the inner wall of the smoke pipe 521, which is difficult to remove, affecting the smoke exhaust efficiency. In order to solve the above problems.

[0038] During the specific use of the present invention, when the surface temperature of the static contact 13 and the moving contact 14 rises, in order to avoid the generation of soot and smoke residue, which affects the conductivity; the thermal expansion liquid 21 expands when heated, and the lower pressure plate 22 slides in the expansion shell 27, and the lower pressure plate 22 drives the displacement rod 23 to descend, and the spiral bevel on the displacement rod 23 presses down, and the downward pressure of the spiral bevel causes the rotating gear 24 to rotate, and the rotating gear 24 drives the rotating gear ring 31 to rotate, and the rotating gear ring 31 drives the high-temperature resistant scraper 32 to rotate, and the high-temperature resistant scraper 32 fits with the static contact 13 and the moving contact 14, and the high-temperature resistant scraper 32 rotates along the surface of the static contact 13 and the moving contact 14. The rotation of the high-temperature resistant scraper 32 can scrape off the soot or smoke residue generated on the surface of the static contact 13 and the moving contact 14, thereby reducing the safety hazards of the static contact 13 and the moving contact 14.

[0039] When scraping off the soot and soot on the surface of the static contact 13 and the moving contact 14, in order to avoid the soot and soot being difficult to scrape off and falling off easily, resulting in poor contact; when the high-temperature resistant scraping strip 32 rotates, the high-temperature resistant scraping strip 32 drives the dial shaft 41 and the arc-shaped limit strip 44 to rotate. When the dial shaft 41 rotates and passes through the elastic strip 42, the dial shaft 41 moves the elastic strip 42 away from the static contact 13 and the moving contact 14. The end of the elastic strip 42 passes through the arc-shaped limit strip 44. At this time, the elastic strip 42 rebounds and drives the knocking ball 43 to knock on the static contact 13 and the moving contact 14, causing the static contact 13 and the moving contact 14 to vibrate, and removing the soot and soot on the surface of the static contact 13 and the moving contact 14 through vibration.

[0040] When smoke is generated on the surface of the static contact 13 and the moving contact 14, in order to prevent the smoke from blackening the components, causing poor contact of the components, reducing conductivity, and posing a safety hazard; the thermal expansion liquid 21 expands due to heat, the upper pressure plate 511 drives the support column 512 to rise, the support column 512 drives the rack 513 to rise, the rack 513 drives the driving gear 514 to rotate, the driving gear 514 drives the large diameter pulley 515 to rotate through the rotating shaft, the large diameter pulley 515 drives the small diameter pulley 525 to rotate through the high temperature resistant leather, and the large diameter pulley 515 is larger than the diameter of the small-diameter pulley 525, which can increase the rotation speed of the small-diameter pulley 525. The small-diameter pulley 525 drives the rotating rod 523 to rotate, and the rotating rod 523 drives the fan blades 524 to rotate. The rotation of the fan blades 524 generates air pressure in the boost chamber 522, which makes the air flow in the smoke pipe 521 flow faster, increasing the gas flow rate in the smoke pipe 521. The smoke collecting nozzle 527 gathers the smoke into the smoke pipe 521, and the smoke is discharged outward through the smoke pipe 521, avoiding blackening of components, improving conductivity, and reducing failure rate.

[0041] When smoke is exhausted around the static contact 13 and the moving contact 14, in order to avoid a lot of soot adhering to the inner wall of the smoke pipe 521 and affecting its use, and to scrape off the soot and residue and vibrate and clean the surfaces of the static contact 13 and the moving contact 14; when the dial shaft 41 contacts the elastic strip 42, the elastic strip 42 has a certain resistance to the dial shaft 41. According to the above, the lower pressure plate 22 also produces resistance, which reduces the downward movement speed of the lower pressure plate 22. According to the temperature thermal expansion liquid 21, the expansion amount remains unchanged, the upward movement speed of the upper pressure plate 511 increases, the upward movement speed of the rack 513 increases, and the rack 513 drives the rotation speed of the driving gear 514 and the large diameter pulley 515 to increase at the same time. The large diameter pulley 515 drives the rotation speed of the small diameter pulley 525 to further increase. The speed of the fan blade 524 increases step by step, and the small-diameter pulley 525 drives the fan blade 524 to increase its rotation speed, and the gas circulation in the smoke tube 521 increases. When the dial shaft 41 is not in contact with the elastic strip 42, similarly, the downward speed of the lower pressure plate 22 increases, and the upward speed of the upper pressure plate 511 decreases, the speed of the fan blade 524 decreases, and the gas circulation in the smoke tube 521 decreases. By rotating the rotating gear ring 31, the air flow circulation in the smoke tube 521 can be continuously reduced or increased, and an air pressure pulse can be generated in the smoke tube 521, which can clean the soot attached to the inner wall of the smoke tube 521, and the gas flow rate around the static contact 13 and the moving contact 14 can be changed with the air pressure pulse in the smoke tube 521 to clean the soot on the surface of the static contact 13 and the moving contact 14.

[0042] When the temperature of the static contact 13 and the moving contact 14 reaches the maximum value, in order to avoid burning the circuit breaker body 7 and causing a safety hazard; the thermal expansion liquid 21 further expands due to the heat, the lower pressure plate 22 drives the displacement rod 23 to continue to descend, the displacement rod 23 presses down the top column 28, the top column 28 drives the moving contact plate 12 to descend, and the moving contact plate 12 drives the moving contact 14 to descend. At this time, the moving contact 14 is separated from the static contact 13 and the power is cut off to increase safety.

[0043] In summary, the rotation of the high-temperature resistant scraper 32 can scrape off the soot or soot residue generated on the surface of the static contact 13 and the moving contact 14, and remove the soot and soot residue on the surface of the static contact 13 and the moving contact 14 through vibration. The rotation of the fan blade 524 can increase the gas flow in the smoke tube 521, and an air pressure pulse can be generated in the smoke tube 521 during vibration, which can clean the soot attached to the inner wall of the smoke tube 521 and change the gas flow rate around the static contact 13 and the moving contact 14 with the air pressure pulse in the smoke tube 521. When the temperature of the static contact 13 and the moving contact 14 reaches the maximum value, the moving contact 14 is separated from the static contact 13 and the power is cut off.

[0044] Example 3 A monitoring method for a switch circuit breaker monitoring device comprises the following steps: S1. The thermal expansion liquid 21 expands due to heat, driving the expansion component 2, which drives the scraping component 3 to rotate the high-temperature resistant scraping strip 32 to scrape off the soot and residue; S2. When the scraping assembly 3 is scraping off soot and smoke residue, the scraping assembly 3 drives the vibration assembly 4 to drive, and the vibration assembly 4 knocks and vibrates the soot and smoke residue on the surfaces of the static contact 13 and the movable contact 14 to clean them; S3, the thermal expansion liquid 21 expands due to heat, driving the smoke exhaust assembly 5, causing the fan blades 524 to rotate, generating air pressure in the smoke pipe 521 to increase the smoke flow rate; S4. When the dial shaft 41 and the elastic strip 42 are in continuous contact, the gas flow in the smoke tube 521 is continuously increased, and a pressure pulse is generated in the smoke tube 521, which can clean the soot attached to the inner wall of the smoke tube 521; S5. When the temperature of the thermal expansion liquid 21 reaches the maximum value, the thermal expansion liquid 21 expands due to the heat to drive the expansion component 2, and the expansion component 2 drives the movable contact plate 12 to move downward. At this time, the movable contact 14 and the static contact 13 are separated and the power is cut off.
