It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and should not be construed as indicating or implying relative importance.

[0021] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] As Figures 1 to 3 shown, the intelligent circuit breaker 100 with temperature acquisition of the present utility model includes a housing 1, a circuit breaker handle 2 provided on the housing 1, a plurality of static contact connection lines 3 provided in the housing 1, a main circuit board 4 for controlling the intelligent circuit breaker 100 with temperature acquisition, an incoming line end temperature acquisition circuit board 5 plugged into the main circuit board 4, a first temperature sensor 6 provided on the incoming line end temperature acquisition circuit board 5, a plurality of outgoing line connectors 7 provided in the housing 1, an outgoing line end temperature acquisition circuit board 8 provided in the housing 1, and a second temperature sensor 9 provided on the outgoing line end temperature acquisition circuit board 8.

[0023] A first slot 11 and a second slot are provided on the housing 1, and the first slot 11 and the second slot are respectively used to support the incoming line end temperature acquisition circuit board 5 and the outgoing line end temperature acquisition circuit board 8.

[0024] The number of the static contact connecting wires 3 is multiple, and correspondingly, the number of the outgoing line connecting parts 7 is also multiple, and both are the same as the number of the first temperature sensors 6 and the second temperature sensors 9. In this embodiment, the number is three. Each of the static contact connecting wires 3 corresponds to one of the circuit breaker handles 2, but the number of the circuit breaker handles 2 can be more than three. In this embodiment, the number of the circuit breaker handles 2 is four. A leakage function coil 10 is provided below one of the circuit breaker handles 2. Since the leakage function coil 10 does not easily generate heat, a corresponding temperature sensor does not need to be provided.

[0025] The first temperature sensor 6 is located above the static contact connecting wire 3. The number of the first temperature sensors 6 is multiple, and one of the first temperature sensors 6 is correspondingly provided on each of the static contact connecting wires 3.

[0026] The first temperature sensor 6 is used to detect the temperature of the corresponding static contact connecting wire 3. The first temperature sensor 6 is electrically connected to the incoming line temperature acquisition circuit board 5 to transmit the acquired temperature information to the incoming line temperature acquisition circuit board 5.

[0027] The multiple static contact connecting wires 3 are arranged at intervals in the horizontal direction. One of the circuit breaker handles 2 is correspondingly provided on each of the static contact connecting wires 3.

[0028] The incoming line temperature acquisition circuit board 5 extends in the horizontal direction. The main circuit board 4 extends in the vertical direction and is perpendicular to the incoming line temperature acquisition circuit board 5.

[0029] One end of the incoming line temperature acquisition circuit board 5 is inserted into the first slot 11, and the other end is in plug-in fit with the main circuit board 4 through a connection terminal 51. The connection terminal 51 can transmit the temperature information acquired by the incoming line temperature acquisition circuit board 5 to the main circuit board 4. The main circuit board 4 compares the acquired temperature with a set threshold value. If it exceeds the threshold value, an alarm is issued or the corresponding circuit breaker handle 2 is closed to prevent electrical fires and the like.

[0030] Each of the outgoing line connecting parts 7 is electrically connected to one of the static contact connecting wires 3. If the outgoing line connecting part 7 is not tightened, it is also easy to generate high temperature and cause an electrical fire. Therefore, in this embodiment, an outgoing line temperature acquisition circuit board 8 and the second temperature sensor 9 thereon are additionally provided.

[0031] The second temperature sensor 9 is arranged above the outgoing line connecting part 7. The outgoing line temperature acquisition circuit board 8 is electrically connected to the main circuit board 4.

[0032] One end of the outgoing line terminal temperature acquisition circuit board 8 is inserted into the second slot, and the other end is plugged and matched with the main circuit board 4 to be electrically connected to the main circuit board 4. The second temperature sensor 9 detects the temperature of the corresponding outgoing line connector 7. The outgoing line terminal temperature acquisition circuit board 8 acquires the corresponding temperature information and transmits it to the main circuit board 4. The main circuit board 4 compares the detected temperature information with the pre-stored threshold value. If an abnormality occurs, an alarm is issued or the corresponding circuit breaker handle 2 is closed to prevent electrical fires caused by excessive temperature at the outgoing line connector 7 and the like.

[0033] For the intelligent circuit breaker 100 with temperature acquisition of the present utility model, by setting the first temperature sensor 6, the temperature of the static contact connection line 3 can be acquired, so that when the temperature of the static contact connection line 3 is too high, it can be monitored in time and the data can be fed back, and at the same time, the circuit breaker is opened to protect the circuit system and prevent electrical fires.

[0034] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0035] The above-described embodiments merely represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
