[0017] Beneficial effects

[0018] The present invention provides a high-precision travel monitoring system for circuit breakers. Compared with the prior art, it has the following advantages:

[0019] (1) The high-precision travel monitoring system of the circuit breaker is provided with a monitoring mechanism in the device. When the contact rotates, the driving plate drives the rotating block and the connecting frame to move, and the connecting frame drives the pointer to move. The user can directly observe the movement trajectory of the pointer through the tempered glass. The pointer cooperates with the scale to facilitate the user to read the horizontal travel of the connecting frame. The horizontal travel of the connecting frame is equal to the horizontal travel of the contact in the contact. The vertical travel of the contact can be calculated by the length of the driving plate and the Pythagorean theorem. During the movement of the connecting frame, the sensor is squeezed by the connecting ring, spring and connecting column. The sensor cooperates with the pressure gauge to display the squeezing force on the pressure gauge. The pressure gauge outputs the squeezing data to the processor, and the processor records the data at all times.

[0020] (2) The high-precision stroke monitoring system of the circuit breaker is configured to provide a first regulating member in the monitoring mechanism to periodically switch the direction of the three-way solenoid valve. Gas is ejected from the back end of the pointer through the three-way solenoid valve and the second pipe. The gas ejected from the second pipe blows and cleans the surface of the scale to avoid affecting the user's reading.

[0021] (3) The high-precision stroke monitoring system of the circuit breaker is provided with a second regulating member in the monitoring mechanism. The air pump extracts the external gas through the anti-blocking member. The extracted gas is injected into the heat dissipation block through the first pipe, and then the gas is injected into the airbag through the connecting pipe, the first regulating member and the third pipe. The airbag gradually expands. The expanded airbag drives the connecting rod, the connecting column, the second cleaning brush and the jet ring to move away from the airbag end. During this process, the second cleaning brush gradually cleans the side wall of the driving plate and the connecting frame, and promotes the removal of impurities attached to their surfaces. When the jet ring protrudes from the rotating block, the gas in the airbag is ejected from the connecting rod and the jet ring. The gas ejected by the jet ring promotes the separation of the detached impurities from the driving plate and the connecting frame. The separated impurities fall into the recovery tank, and then the solenoid valve is started. The gas in the fourth pipe is injected into the upper end of the driving plate through the fourth pipe and the solenoid valve and ejected. The ejected gas dissipates heat for the electromagnetic coil.

[0022] (4) The high-precision stroke monitoring system of the circuit breaker is equipped with an anti-blocking device in the device. During the operation of the air pump, the gas pumped by the air pump drives the impeller to rotate when passing through the casing, and the impeller drives the filter ring to rotate. The first cleaning brush cleans the impurities attached to the surface of the rotating filter ring to avoid blockage. BRIEF DESCRIPTION OF THE DRAWINGS

The switch 4 drives the dial block 6 and the contact 7 to rotate through the connecting block 5. At this time, the dial block 6 is engaged with the lever 11, and the contact 7 is fitted with the first conductive block 3. At this time, the circuit is connected, and the current flows to the load end through the first terminal block 2, the first conductive block 3, the contact 7, the electromagnetic coil 10, the metal sheet 13, the conductive plate 14, the second conductive block 15, and the second terminal block 16. When the current is overloaded, the metal sheet 13 is bent by heat and the conductive plate 14 and the lever 11 is lifted up, and the lever 11 toggles the toggle block 6, which separates the contact 7 from the first conductive block 3 through the connecting block 5 and resets the switch 4 to achieve overload protection. When the line is short-circuited or severely overloaded, the electromagnetic coil 10 generates a large magnetic field, and the iron block at the bottom of the electromagnetic coil 10 is magnetized. The magnetized iron block is attracted by the iron sheet on the surface of the toggle 12 to achieve the rotation of the toggle 12 and the lever 11. The lever 11 toggles the toggle block 6, which separates the contact 7 from the first conductive block 3 through the connecting block 5 and resets the switch 4 to avoid safety hazards. In the above process, when the contact 7 rotates, the driving plate 816 drives the rotating block 813 and the connecting frame 818 to move, and the connecting frame 818 drives the pointer 8153 to move. The user can directly observe the movement through the tempered glass 18. Observe the movement trajectory of pointer 8153. Pointer 8153 cooperates with scale 82 to facilitate the user to read the horizontal stroke of connection frame 818. The horizontal stroke of connection frame 818 is equal to the horizontal stroke of the contact in contact 7. The vertical stroke of the contact can be calculated by the length of driving plate 816 and Pythagorean theorem. During the movement of connection frame 818, sensor 872 is squeezed by connecting ring 84, spring 86 and connecting column 871. Sensor 872 cooperates with pressure gauge 88 to display the squeezing force on pressure gauge 88. Pressure gauge 88 outputs the squeezing data to processor 89. Processor 89 records the data at all times. The displacement of connection frame 818 can be obtained by pressure and elastic coefficient of spring 86. The obtained displacement is consistent with pointer 8153 and scale 8 2 can be compared with the displacement read to form a verification. At the same time, the air pump 8111 extracts external gas through the anti-blocking member 8112, and the extracted gas is injected into the heat dissipation block 8123 through the first pipe 8121. Then the gas is injected into the airbag 8172 through the connecting pipe 814, the first adjusting member 815, and the third pipe 8171. The airbag 8172 gradually expands, and the expanded airbag 8172 drives the connecting rod 8173, the connecting column 8174, the second cleaning brush 8175, and the jet ring 8176 to move away from the airbag 8172. During this process, the second cleaning brush 8175 gradually cleans the side walls of the driving plate 816 and the connecting frame 818, promoting the removal of impurities attached to their surfaces. When the jet ring 8176 protrudes out of the rotating block 813,The gas in the airbag 8172 is ejected from the connecting rod 8173 and the jet ring 8176. The gas ejected from the jet ring 8176 promotes the separation of the impurities from the driving plate 816 and the connecting frame 818. The separated impurities fall into the recovery tank 83, and then the solenoid valve 8178 is activated. Part of the gas in the fourth pipe 8177 is injected into the upper end of the driving plate 816 through the fourth pipe 8177 and the solenoid valve 8178 and ejected. The ejected gas dissipates heat to the electromagnetic coil 10, and the three-way solenoid valve 8151 is reversed at a certain time. The gas passes through the three-way solenoid valve 8151 and the second pipe 8178. 52 is ejected from the back of pointer 8153. The gas ejected from second pipe 8152 cleans the surface of scale 82. After turning off air pump 8111, the buffer wire inside second adjusting member 817 resets all links inside second adjusting member 817. During the operation of air pump 8111, the gas pumped by air pump 8111 passes through housing 81121, driving impeller 81122 to rotate. Impeller 81122 then drives filter ring 81123 to rotate. First cleaning brush 81124 cleans impurities attached to the surface of rotating filter ring 81123 to prevent clogging.
