[0023] Two rows of outgoing line chambers 3 are arranged side by side directly below the busbar chamber 2. A circuit breaker is provided in the outgoing line chamber 3 to control the current. When the current is overloaded, the circuit breaker starts to disconnect the current.

[0024] The busbar chamber 2 and the outgoing line chamber 3 are separated by a busbar chamber partition 4. Under the action of the busbar chamber partition 4, the busbar chamber 2 and the outgoing line chamber 3 are separated, so that the busbar chamber 2 is an independent space;

[0025] Two adjacent outgoing line chambers 3 are separated by an outgoing line chamber partition 5. Under the action of the outgoing line chamber partition 5, the outgoing line chambers 3 exist independently, and a single outgoing line chamber 3 can be processed separately.

[0026] A busbar frame 7 for carrying the main busbar 6 is provided in the busbar chamber 2. The busbar frame 7 is used to fix the main busbar 6 on the one hand, and to shunt the main busbar 6 on the other hand to separate multiple independent vertical busbars 8. The busbar frame 7 is provided with multiple vertical busbars 8 arranged in sequence along its length direction. The starting end of the vertical busbar 8 is connected to the main busbar 6, and the end of the vertical busbar 8 is connected to the corresponding outlet chamber 3.

After the fixing is completed, the outgoing circuit breaker 9 is opened, and the current flows into the wire. At the same time, under the action of the current transformer 16, the current will not flow in too much in a short time, so the electrical appliances can be protected. Moreover, since the multiple outgoing chambers 3 exist independently, when operating one of the short-circuit chambers, it will not cause interference to the other outgoing chambers 3.
