Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome that the two trigger devices in the prior art are only used to detect the opening and closing state of the circuit breaker, and it is impossible to distinguish whether the circuit breaker is tripping, fault opening or normal opening. And the installation structure of the two trigger devices on the circuit breaker is complicated, the installation and replacement operations are inconvenient, and the installation cost is high

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;...

Abstract

The invention discloses a modularized intelligent measurement circuit breaker integrating signal indication and communication functions, which comprises a shell assembly, a driving rotating shaft and a signal alarm device mounted in a mounting groove structure through a connecting structure, and is characterized in that the signal alarm device comprises a first switch structure, a second switch structure and a power supply unit device which are mounted on a shell frame structure; the first switch structure and the second switch structure are respectively provided with a first contact pin and a second contact pin which extend on a rotation path of the driving rotating shaft, the signal alarm device adopting the technical scheme is simple in structure, modularized and integrated installation can be realized, the occupied installation space is small, the installation and replacement operations of the two switch structures on the circuit breaker are facilitated, and the installation cost is reduced. According to the invention, the setting cost is reduced, a power supply can be provided for the carrier communication device through the power supply unit device, the opening and closing state information of the circuit breaker can be detected through the two switch structures, whether the circuit breaker is normally opened or is tripped and opened due to a fault can be distinguished, and the use safety of the product is ensured.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a modular intelligent measuring circuit breaker with integrated signal indication and communication functions. Background technique [0002] The existing intelligent circuit breaker has overload long-time delay and short-circuit instantaneous protection functions, and can also be used in conjunction with the communication carrier module to realize intelligent communication functions. The most common way for this kind of communicable intelligent circuit breaker to output opening and closing signals is this The opening and closing signals are provided by the auxiliary contact attachment installed in the circuit breaker housing. This auxiliary contact attachment takes up a lot of space and is easily unable to be installed due to the space limitation of the circuit breaker housing. The installation matching is very poor. [0003] For this reason, Chinese patent document CN20...
