Problems solved by technology

[0003] However, when the fault indication unit of the existing intelligent circuit breaker is in use, the display of the fault cause of the intelligent circuit breaker is relatively general, which causes the staff to carry out a large amount of investigation work during maintenance and reduces the work efficiency of the staff. In view of the above problems, Propose a fault indication unit of intelligent circuit breaker

Embodiment 1

[0029] see figure 1 , the fault indication unit of the intelligent circuit breaker, including the fault indication unit, the indication unit includes the data acquisition module, the intelligent identification module, the electronic control module, the adjustment module, the signal display module and the switching module, the output end of the data acquisition module and the intelligent identification module The output end of the intelligent identification module is connected with the input end of the electronic control module, and the output end of the electronic control module is respectively connected with the input end of the adjustment module, the input end of the signal display module and the input end of the splitting module.

Embodiment 2

[0031] see figure 2 , the data acquisition module is used to monitor the working status of the intelligent circuit breaker and the lines connecting each circuit in real time, and collect the information of the target circuit that has failed, so as to grasp the working status of each part of the intelligent circuit breaker in time, and it is convenient to The fault line of the intelligent circuit breaker is grasped in time, and the overload of the intelligent circuit breaker is monitored through the temperature sensor 4 to ensure the comprehensiveness of the information collection of the intelligent circuit breaker. The intelligent identification module is used to judge and identify which part of the circuit of the intelligent circuit breaker is faulty. Reduce the fault scope of the intelligent circuit breaker and clarify the fault cause of the intelligent circuit breaker.

Embodiment 3

[0033] see figure 2 , the electronic control module is used to perform different operations according to the fault information identified by the intelligent identification module and the preset programming logic. When the electronic control module sends the fault information to the signal display module, the signal display module displays the fault information, so as to facilitate The staff can grasp the fault information in time. During the signal display, the signal display module broadcasts the fault cause in real time according to the fault information, and flashes and beeps the alarm light. The staff repairs the intelligent circuit breaker through the fault information displayed by the signal display module.

Abstract

The invention relates to the technical field of intelligent circuit breakers, and discloses a fault indication unit which comprises a data acquisition module, an intelligent identification module, an electronic control module, an adjustment module, a signal display module and an opening and closing module. The fault range of the intelligent circuit breaker is narrowed, the fault reason of the intelligent circuit breaker is determined, the signal display module broadcasts the fault reason in real time according to the fault information, and flickers and sounds an alarm lamp, so that a worker can timely master which part of the intelligent circuit breaker has a fault, the intelligent circuit breaker is convenient to maintain, and the working efficiency is improved. A large amount of troubleshooting of fault reasons of the intelligent circuit breaker is avoided, low-speed disconnection when the current is small and high-speed disconnection when the current is large are adjusted through the adjusting module, so that the optimal disconnection effect in electrical and mechanical properties is obtained, motion characteristics adaptive to the current system working state are obtained, and the working performance of the intelligent circuit breaker is ensured.

Description

technical field [0001] The invention relates to the technical field of intelligent circuit breakers, in particular to a fault indication unit of an intelligent circuit breaker. Background technique [0002] The intelligent circuit breaker mechanism is located on the front of the circuit breaker. The mechanism adopts a five-link free release mechanism and is designed in the form of energy storage. During the use of the intelligent circuit breaker, the mechanism is always in the pre-energy storage position. As long as the circuit breaker is connected When the closing command is reached, the circuit breaker can be closed instantly, the release of the pre-stored energy is completed by the button or the closing electromagnet, the electric transmission mechanism is self-contained, and the energy-storing shaft and the main shaft are movably connected by a concave-convex wedge. It is easy to assemble and disassemble. The intelligent circuit breaker is used to control and protect the...
