The circuit breaker is important electrical equipment of a power plant and a transformer substation, and is used for throwing in or withdrawing from the electrical equipment in normal time to change the running mode of a power grid; and the fault state is used for cutting off fault equipment, so that the system can continue to operate safely. In power plants and substations, circuit breakers of 220kV and above are commonly operated in split-phase mode. The control loop and the operating mechanism realize the split-phase opening and closing of the breaker.

A phase-splitting circuit breaker 100 according to an embodiment of the present utility model. The phase-splitting circuit breaker 100 includes a mechanism housing 10, a junction housing 20, and an interphase cable 30. The mechanism housing 10 may also be referred to as a mechanism cabinet.

In some embodiments of the present utility model, the mechanism housing 10 may include, for example, A, B, C three-phase mechanism housings (a disconnector may be provided in each mechanism housing). The mechanism box 10 generally has the functions of overload protection, short-circuit protection and the like, and can ensure the safe operation of the circuit.

The junction box 20 (may also be referred to as a junction box) is mainly used for setting electrical components therein, and is referred to as a monitoring device in a power system, and is used for monitoring and controlling an operation state of the power device in real time. The method can acquire parameters such as current, voltage, temperature and the like through the sensor, and transmit the data to the monitoring center, and the monitoring center can remotely monitor and control the power equipment. The control box 20 can monitor the running state of the power equipment in real time, discover abnormal conditions in time and take corresponding measures, so that the reliability and the safety of the power system are improved. The interphase cable 30 is used for connecting the mechanism box 10 and the junction box 20 to realize circuit connection.

The junction box 20 can be connected with three mechanism boxes 10 simultaneously to form a three-phase circuit breaker. Each mechanism housing 10 may be configured as one of three phases A, B, C.

In particular, as shown in fig. 1-3, the mechanism housing 10 includes a first opening 11, a first wire connector 12, a first wire frame 13, and a first wire connector lug 14. The first opening 11 is opened in the bottom wall of the mechanism case 10, whereby the passage of the interphase cable 30 can be achieved by the position of the first opening 11. The first wiring member 12 is detachably provided to the bottom wall of the mechanism case 10 at a position corresponding to the first opening 11. Therefore, when the interphase cable 30 passes through the position of the first opening 11, the interphase cable 30 is matched with the interphase cable 30, the first opening 11 is sealed, and the waterproof performance of the box body is improved.

As shown in fig. 1, a first land 13 is provided to an inner wall of the mechanism case 10, and a first land 14 is detachably connected to the first land 13. It can thus be seen that the first terminal 14 is disposed inside the mechanism housing 10. That is, the position where the interphase cable 30 is connected to the first connector lug 14 is also inside the mechanism case 10, so that the waterproof and dustproof functions can be provided to the connection of the first connector lug 14 and the interphase cable 30 by the case body of the mechanism case 10. Furthermore, the first land 13 serves as a mounting base for the first land 14, can provide a stable mounting platform for the mounting of the first land 14, and can also be connected to the first land 13 with the external housing removed from the first land 14. Compared to the connector lug 200 with the outer housing shown in fig. 4, the first connector lug 14 of the embodiment of the present utility model is smaller in size and lower in manufacturing cost.

The second wiring member 22 is detachably provided to a position of the bottom wall of the junction box 20 corresponding to the second opening 21. Therefore, when the interphase cable 30 passes through the position of the second opening 21, the interphase cable 30 is matched with the interphase cable 30, the position of the second opening 21 is sealed, and the waterproof performance of the box body is improved.

As shown in fig. 2 and 8 to 10, a second land 23 is provided to the inner wall of the junction box 20, and a second land 24 is detachably provided to the second land 23. It can thus be seen that the second connector lug 24 is disposed inside the junction box 20.

The first connector lug 14 is shown in fig. 5 as an example. The second terminal 24 is disposed in the position shown in the drawing of fig. 2.

As shown in fig. 1 and 2, one end of the interphase cable 30 passes through the first connector 12 into the mechanism box 10 to be connected with the first connector lug 14, and the other end of the interphase cable 30 passes through the second connector 22 into the junction box 20 to be connected with the second connector lug 24. Therefore, the waterproof performance of the interphase cable 30 at the connection with the first connector lug 14 or the second connector lug 24 is ensured, and the outer shells of the first connector lug 14 and the second connector lug 24 are omitted, so that the volumes of the first connector lug 14 and the second connector lug 24 can be reduced, and the manufacturing cost is reduced.

According to the split-phase circuit breaker 100 of the present utility model, the first connector lug 14 is connected to the first connector lug 13 by providing the first connector lug 13 inside the mechanism case 10, and the first opening 11 is opened in the bottom wall of the mechanism case 10, so that one end of the inter-phase cable 30 can be connected to the first connector lug 14 through the first opening 11.
