[0002] Circuit breakers are important electrical equipment used for circuit protection. They mainly play a role in safety protection in power systems and low-voltage power distribution systems. When overload, short circuit or undervoltage occurs in the circuit, the circuit breaker can quickly cut off the circuit to prevent electrical equipment from being damaged due to abnormal current and effectively prevent safety accidents such as fire.

[0003] At present, more and more circuit breakers can view the power consumption of the circuit connected to the circuit breaker, and users can set the working parameters of the circuit breaker according to the power consumption, such as the trip current threshold. If the circuit connected to the circuit breaker by the user is a high-power appliance, and the appliance often trips during use, the trip current threshold can be appropriately increased. However, in order to prevent children from misoperating, general circuit breakers are usually set at a higher position indoors or in a place that is not easy to touch.

The contact system is responsible for connecting and disconnecting the circuit. When the circuit breaker needs to be operated, the moving contact will quickly separate from the static contact to cut off the current flow. The tripping mechanism usually performs a tripping operation after detecting an abnormal situation to ensure that the contact is quickly disconnected.

In addition, the strong electric environment around the circuit breaker can be avoided to avoid the risk of electric shock during the operation process.

The actuator 2 includes a second magnetic member 8, and the second magnetic member 8 is provided on the housing of the actuator 2; the second magnetic member 8 is provided corresponding to the first magnetic member 3.

[0064] The embodiment of the utility model uses the first magnetic component 3 and the second magnetic component 8 to detachably connect the actuator 2 and the setting mechanism 1. Compared with other connection methods that require holes and additional mounting parts, the magnetic component can be realized without holes and mounting parts, and can be directly disassembled and installed, which greatly facilitates the use of technicians.

[0065] Furthermore, in an optional embodiment, the setting mechanism 1 further includes a plurality of heat sinks 111 and a battery pack 128.

The display screen 123 is at least used to view the working parameters of the actuator 2. For the specific functions of the display screen 123, those skilled in the art may change it according to the actual application of the circuit breaker.

[0073] Furthermore, a display window 124 is opened on the operation panel 122; the display window 124 is arranged corresponding to the display screen 123, and after the operation panel 122 and the operation main board 121 are installed in the bottom shell 11, the display screen 123 can be flush with the display window 124, so that the technician can watch it normally.

[0074] Furthermore, in an optional implementation, a positioning notch 1211 is provided around the operating mainboard 121 , and a positioning step corresponding to the positioning notch 1211 is provided in the bottom shell 11 .

Furthermore, the positioning notch 1211 also plays a fool-proof role, preventing the installer from installing the operating mainboard 121 in the wrong direction during the installation process, further improving the installation efficiency.

[0076] Further, in an optional embodiment, the operating component 12 further includes a warning light 125, a warning light cover 126 and a through hole 127.

[0077] In this way, by setting the warning light 125, the embodiment of the utility model can allow technicians to determine whether the circuit breaker itself is in an emergency state, such as damage, overvoltage, short circuit, etc., according to the working status of the warning light 125, so that maintenance personnel can directly maintain the circuit breaker without the need to carefully check the circuit breaker, thereby improving maintenance efficiency.

[0078] Further, in an optional embodiment, the actuator 2 is provided with a first interface 10 on the housing facing the setting mechanism 1, the operating mainboard 121 is provided with a second interface 6 on the side away from the display screen 123, the bottom shell 11 is provided with a through hole 115 on the end face close to the first interface 10, and the second interface 6 is provided corresponding to the through hole 115, so that when the user uses it, he can directly align the first interface 10 with the through hole 115 and then insert it into the second interface 6 to complete the docking.

[0079] Furthermore, the interface type of the first interface 10 can be a USB interface, or other male or female connectors. During the installation process, the setting mechanism 1 is first installed, and then the second interface 6 is aligned with the first interface 10, and the bottom shell 11 of the setting mechanism 1 is directly installed on the actuator 2.

[0080] When the setting mechanism 1 is in the integrated state, the second interface 6 is inserted into the first interface 10 or the first interface 10 is inserted into the second interface 6 to connect the setting mechanism 1 and the actuator 2 by wired communication.

In addition, since the operating mainboard 121 can achieve wireless communication with the actuator 2, it can be moved over a large range without first measuring the distance from the power cord, which is convenient for technicians to operate. At the same time, the first interface 10 and the second interface 6 can provide power and charging while providing communication, integrating different functions, thereby improving the functionality of the first interface 10 and the second interface 6, and facilitating the use of technicians.

During the installation process, the guide groove 21 and the guide boss 114 are aligned, and the setting mechanism 1 can be directly slid to the installation position of the actuator 2. Compared with the technicians personally aligning and installing, it can obviously reduce the installation steps of the technicians and also has an anti-fool effect.

[0088] Furthermore, in an optional embodiment, the actuator 2 is provided with a status light 22 and an execution button 23 ; the status light 22 is used to indicate the working state of the actuator 2 ; and the execution button 23 is used to control the working state of the actuator 2 .

[0090] In such a configuration, since a single setting mechanism 1 and a single actuator 2 are paired to work in a traditional circuit breaker, the embodiment of the utility model uses a single setting mechanism 1 to communicate with multiple actuators 2 at the same time, so that the entire working process can be realized only by a single setting mechanism 1, which can significantly reduce the number of setting mechanisms 1 used and, to a certain extent, can reduce production costs and improve product competitiveness.
