Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, in particular to an intelligent circuit breaker with a load characteristic identification function. Background Art

[0002] A circuit breaker is an electrical device used to protect an electrical circuit from damage due to electrical faults such as overload, short circuit and ground fault. Its main function is to interrupt the flow of current in a circuit to avoid overloading the circuit or damaging the electrical appliances.

[0003] However, although the existing circuit breakers are capable of short-circuit fault detection and non-directional wiring, due to changes in electrical equipment, even if the old circuit breaker is not damaged, it is still necessary to replace the circuit breaker with a different rated current, resulting in a waste of resources. At the same time, the existing circuit breaker cannot be forcibly disconnected to protect the electrical equipment when a jump occurs.

[0004] The existing patent (Announcement No.: CN 116344285 A) discloses: an intelligent circuit breaker with a load characteristic recognition function, including a housing component, which, through the mutual cooperation between the load characteristic recognition component, the bimetallic strip, etc., firstly, realizes real-time detection of the current in the load circuit by detecting the change of the magnetic flux, and secondly, detects and determines the cause of the circuit breaker fault or circuit fault through the mutual cooperation between the load characteristic recognition component, the bimetallic strip, etc., and through the mutual cooperation between the load characteristic recognition component, the bimetallic strip, etc., firstly, after the rated current is adjusted, the resistance value of the sliding rheostat is adjusted to simulate the electrical equipment in the load circuit, and the corresponding relationship between the current and the magnetic flux detected by the magnetic flux sensor is obtained. The system is corrected so that the new real-time detected current is accurate, avoiding errors in the real-time detected current due to adjustment of the rated current; secondly, even if the circuit breaker jumps due to sticking of the moving and static contacts, it can still cut off the power to protect the electrical equipment. By setting an arc extinguishing component, the arc extinguishing component includes multiple arc extinguishing plates, and the arc extinguishing plates are arranged on one side of the conductive rod and the conductive block. When the conductive rod contacts or separates from the conductive block to generate an arc, the arc enters the groove on one side of the arc extinguishing plate. At this time, the arc disappears after multiple reflections in the groove, thereby achieving the extinguishing of the arc, thereby avoiding damage to the remaining components in the device by the arc, thereby ensuring the normal use of the device.

[0005] However, the above technical solution still has certain defects. When connecting the cable and the circuit breaker, the contact piece and the screw need to cooperate to fix them. After fixing, a gap is set between the cable and the circuit breaker. When there is moisture in the air, it contacts the contact piece, causing oxidation damage to the contact piece, resulting in poor contact. Therefore, an intelligent circuit breaker with load characteristic recognition function is proposed. Utility Model Content

One side of the moving column 220 is connected to the connecting column 240 through the rotating column 230, and the rotating column 230 is rotatably installed on the inner wall of the circuit breaker body 110 through the rotating rod 320. One end of the connecting column 240 is slidably installed in the inside of the mounting cylinder, and the other end of the connecting column 240 is fixedly connected to the rubber pad 250. The push rod 270 is slidably installed on the inner wall of the cylinder 280, and a spring is provided between the cylinder 280 and the push rod 270, and the cylinder 280 is connected to the air bag 2910 through the pipe 290.

[0024] The insulating column 130 drives the contact piece 120 into the inside of the socket 140. When the insulating column 130 moves to a certain position, the extrusion block 210 is squeezed. The extrusion block 210 drives the movable column 220 to move outward, and at the same time, one end of the rotating column 230 and the connecting column 240 move inward, and then drives the rubber pad 250. The insulating column 130 is positioned by the rubber pad 250.
