Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, and in particular to a protection control system and method for an intelligent circuit breaker. Background Art

[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions, and closing, carrying, and interrupting current under abnormal circuit conditions within a specified timeframe. Circuit breakers are categorized as high-voltage and low-voltage based on their scope of use. The distinction between high and low voltage is relatively vague, with those above 3kV generally considered high-voltage. Circuit breakers are used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. They automatically disconnect circuits in the event of severe overloads, short circuits, or undervoltage faults. Their functionality is equivalent to a combination of a fuse-type switch and an over- and under-voltage relay. Furthermore, interrupting fault current generally requires no component changes. Currently, circuit breakers have found widespread application. Power distribution is a crucial link in the generation, transmission, and use of electricity. Power distribution systems include transformers and various high- and low-voltage electrical equipment. Low-voltage circuit breakers are widely used.

[0003] When an existing circuit breaker trips, people need to push the switch up. The circuit breaker will age after long-term use. When the circuit breaker trips and energizes, the switch will collide with the housing, causing a certain degree of damage to the switch. In addition, the circuit breaker switch is made of plastic. When pushing the switch up, due to excessive force, the switch is easy to break, and then it is easy to scratch people's hands.

[0014] Preferably, a mounting plate is integrally formed on the front and back sides of the fixing body, and a mounting hole is formed through one side of the mounting plate.

[0015] The present invention also discloses a method for controlling a protection system of an intelligent circuit breaker, which specifically includes the following steps:

[0016] S1. Auxiliary Mechanism Installation: First, compress the guide rod into the movable chamber and tilt the bottom plate. Then, place the barrel into the first groove through the first through-slot and loosen the guide rod. Then, insert the bottom end of the guide rod into the second groove. Then, align the first through-slot so that the second through-slot is aligned with the first and second thread grooves.

[0017] S2. Install the fixed body: Then, align the mounting holes with the holes on the intelligent circuit breaker body, and then fix the fixed body with screws;

[0018] S3. Power supply to the circuit breaker: Then, the protrusion is pushed upward to the left, thereby driving the second connecting plate to move upward to the left, thereby driving the push rod to move through the connecting arm, and then the push rod drives the switch on the intelligent circuit breaker body to move upward, and the bottom plate rotates upward via the first rotating shaft, so that the cylinder rotates on the screw through the rotating plate, and the guide rod compresses the buffer spring.

Since the initial position of the push rod is in a horizontal state, the switch will contact the push rod during the movement, and the switch and the push rod move to the lowest point together, so that the buffer spring applies elastic force to the bottom plate through the guide rod, so that the switch and the push rod are subject to resistance when moving together, thereby avoiding the switch from colliding with the intelligent circuit breaker body and achieving a protective effect. Therefore, it solves the problem that the switch collides with the shell when the existing circuit breaker trips and supplies power, which will cause a certain degree of damage to the switch.

[0020] Preferably, when the fixed body is fixedly installed in step S2, the switch on the intelligent circuit breaker body needs to be in a tripped state, and the initial state of the buffer spring in step S3 is a compressed state.

[0040] The embodiment of the present invention further discloses a method for controlling a protection system of an intelligent circuit breaker, which specifically includes the following steps:

[0041] S1. Installation of the auxiliary mechanism: First, compress the guide rod 36 into the movable chamber 7 and tilt the bottom plate 204. Then, insert the barrel 34 into the first groove 31 through the first through-slot 202 and loosen the guide rod 36. Then, insert the bottom end of the guide rod 36 into the second groove 32. Then, align the first through-slot 202 so that the second through-slot 332 is aligned with the first thread groove 4 and the second thread groove 5. Then, fix the screw 6 in the first thread groove 4, the second through-slot 332, and the second thread groove 5. Fix the rotating plate 331, thereby fixing the barrel 34.

[0042] S2. Installing the fixed body: Next, align the mounting hole 10 with the hole on the intelligent circuit breaker body 1, and then fix the fixed body 201 with screws;

[0043] S3. Power supply to the circuit breaker: Then, the protrusion 213 is pushed upward to the left, thereby driving the second connecting plate 209 to move upward to the left, thereby driving the push rod 212 to move through the connecting arm 211, and then the push rod 212 drives the switch on the intelligent circuit breaker body 1 to move upward, and the bottom plate 204 rotates upward via the first rotating shaft 203, so that the cylinder 34 rotates on the screw 6 via the rotating plate 331, and the guide rod 36 compresses the buffer spring 352.

[0044] S4. Circuit breaker tripping: Finally, when the intelligent circuit breaker body 1 trips, the switch moves from the highest point to the lowest point. Since the initial position of the top rod 212 is in a horizontal state, the switch will contact the top rod 212 during the movement, and the switch and the top rod 212 move toward the lowest point together, so that the buffer spring 352 applies elastic force to the bottom plate 204 through the guide rod 36, so that the switch and the top rod 212 are subjected to resistance when moving together, thereby avoiding the switch from colliding with the intelligent circuit breaker body 1, achieving a protective effect. Therefore, the problem that the switch collides with the shell when the existing circuit breaker trips and supplies power is solved, which will cause a certain degree of damage to the switch.
