Technical Field

[0001] This application relates to the field of circuit breaker technology, and in particular to a manual / automatic integrated reclosing intelligent circuit breaker. Background Technology

[0002] Reclosing circuit breakers are widely used in low-voltage power distribution networks, mainly in various places such as industry, commerce, high-rise buildings and residential buildings. They can provide overcurrent protection and leakage protection for electrical equipment such as motors, power distribution lines and lighting circuits, and play a role in controlling and protecting circuits. The opening and closing actions of traditional reclosing circuit breakers need to be completed manually.

[0003] With the development of my country's smart grid, the need for intelligent control of electrical appliances is becoming increasingly urgent, while ensuring the safe operation of the power grid. To cope with the new situation, existing reclosing smart circuit breakers, through electric operating mechanisms for remote electric opening and closing, have automatic reclosing functions, enabling the reclosing circuit breaker to open and close under remote signal control. They can be used directly in conjunction with prepaid energy meters to achieve reclosing after payment.

[0004] The existing automatic reclosing circuit breaker has an unreasonable structural design, cannot achieve modular assembly, and has defects such as complex structure, unreliable performance, and inconvenient assembly. Utility Model Content

[0005] This application provides a manual / automatic integrated reclosing intelligent circuit breaker, which has the advantages of simple structure, stable and reliable performance, and convenient assembly.

[0006] The intelligent circuit breaker with manual / automatic integrated reclosing mechanism provided in this application adopts the following technical solution:

[0007] A manual / automatic integrated reclosing intelligent circuit breaker includes a circuit breaker unit and a reclosing device assembled with the circuit breaker unit for controlling the opening and closing operation mechanism in the circuit breaker unit. The reclosing device includes a plastic shell base connected to the circuit breaker unit, a cover plate covering the plastic shell base and forming a cavity therewith, a drive unit installed in the cavity of the plastic shell base, a circuit board, and a linkage unit. The linkage unit is connected between the output end of the drive unit and the opening and closing operation mechanism. An automatic opening and closing button unit is installed on the cover plate, which is electrically connected to the drive unit and controls the opening and closing operation mechanism through the linkage unit. The circuit board is installed on the inner wall of the plastic shell base and is electrically connected to the circuit breaker unit, the drive unit, and the automatic opening and closing button unit. A manual control unit is installed on the cover plate, which acts on the linkage unit to link it and control the opening and closing of the opening and closing operation mechanism through the linkage unit.

[0008] Preferably, the linkage unit includes a rotating plate connected to the output end of the drive unit, a fixed column eccentrically mounted on the rotating plate, a connecting rod movably connected at one end to the fixed column, and a connecting column fixedly mounted on the handle of the opening and closing operation mechanism. The other end of the connecting rod is movably connected to the connecting column. The drive unit drives the rotating plate to rotate, and the manual control unit can act on the fixed column to make the rotating plate rotate.

[0009] Preferably, the manual control unit includes a manual rotating column rotatably mounted on the cover plate and a lever fixedly connected to one end of the manual rotating column. The lever is located in the cavity inside the plastic shell base and can act on the fixed column. The other end of the manual rotating column passes through the cover plate on its outer surface.

[0010] Preferably, the lever is in the shape of a " "Shape setting.

[0011] Preferably, the automatic opening and closing button unit includes an opening and closing button body installed on the outer surface of the cover plate and an opening and closing control module installed in the cavity of the plastic shell base. The opening and closing button body is electrically connected to the opening and closing control module, and the opening and closing control module is electrically connected to the drive unit.

[0012] Preferably, it also includes a circuit breaker unit for opening and closing indication, the circuit breaker unit including an opening and closing indication sign, an indication window being provided on the cover plate, and the opening and closing indication sign being located below the indication window.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] By operating the automatic opening and closing button unit, the drive unit is linked to the linkage unit to operate, which in turn automatically controls the opening and closing mechanism of the circuit breaker. At the same time, by setting up a manual control unit, it acts on the linkage unit to control the opening and closing mechanism of the circuit breaker. By integrating the drive unit, circuit board, linkage unit, automatic opening and closing button unit, and manual control unit into one reclosing device, it is possible to achieve manual and automatic control of the opening and closing mechanism of the intelligent circuit breaker. It also forms a modular and quick assembly with the circuit breaker unit, which has the advantages of simple structure, stable and reliable performance, small size, and convenient assembly.

[0016] By pressing the opening and closing button, the drive unit drives the rotating plate in the linkage unit to rotate. The rotating plate drives the linkage rod to rotate, causing the connecting column to rotate the handle in the opening and closing operation mechanism, thus realizing the opening and closing operation of the circuit breaker unit.

[0017] By operating the manual rotating column to rotate on the cover plate, the lever acts on the fixed column to cause the rotating plate to rotate, which in turn drives the connecting rod to move, thereby achieving the purpose of opening and closing the circuit breaker mechanism.

[0018] During the opening and closing process of the circuit breaker unit, the opening and closing indicator unit is activated by linkage, so that the opening and closing indicator sign displays the opening and closing indicator mark through the indicator window, thereby improving the identification function of the circuit breaker opening and closing.

[0019] By sliding a card slot blocking lever on the cover plate, the installation and removal of the memory card in the memory card module can be facilitated by operating the position of the card slot blocking lever. The memory card module improves the data storage and acquisition of the circuit breaker. Attached Figure Description
