Embodiment 1
[0044] This embodiment provides as Figure 1-9 A modular intelligent measuring circuit breaker with integrated signal indication and communication functions is shown, including:
[0045] The housing assembly 1 includes a base 11 and a middle seat 12, and a drive shaft 9 rotatably arranged between the base 11 and the middle seat 12. The drive shaft 9 has the function of driving the moving contact when the circuit breaker is normally opened. The first position where the head is separated from the static contact to form the first opening distance, and the second position where the moving contact is separated from the static contact to form the second opening distance when the circuit breaker trips due to a fault. The opening distance of the second section is greater than the opening distance of the first section;
[0046] The installation groove structure 8 is arranged on the middle seat 12, and the bottom thereof is provided with a through hole 80 opposite to the drive shaft 9;...
