Description
Technical Field
[0001] The present invention relates to the technical field of circuit breakers, and in particular to an intelligent integrated 10 kV circuit breaker. Background Art
[0002] 10kV circuit breakers are key devices for controlling and protecting circuits in distribution networks. They are used to switch on and off the load current and short-circuit current of 10kV power systems under normal and fault conditions. Their core structure includes an arc extinguishing chamber, an operating mechanism, an intelligent controller, and an insulating shell. They have the characteristics of strong breaking capacity and rapid action. Vacuum circuit breakers account for over 80% of distribution networks due to their high arc extinguishing efficiency and long life. The vacuum degree of their arc extinguishing chambers is maintained at 10⁻ 4 Pa or above, ensuring rapid recovery of insulation strength after disconnection. The intelligent circuit breaker integrates a microcomputer protection device, which can monitor current, voltage and other parameters in real time, supports three-stage overcurrent protection and automatic reclosing, and is connected to the distribution automation system through the RS485 interface.
[0003] Among existing 10 kV circuit breakers, such as the intelligent integrated 10 kV circuit breaker with application number 201220323494.3, its technical solution is as follows: it includes 1-10 kV distribution lines and poles, and an intelligent circuit breaker stainless steel housing box is installed on the pole. The intelligent circuit breaker stainless steel housing box is equipped with a circuit breaker, a circuit breaker operating mechanism, a distribution terminal FTU and a fiber optic junction box. The input and output ends of the circuit breaker are respectively electrically connected to the 1-10 kV distribution lines. The circuit breaker operating mechanism is electrically connected to the distribution terminal FTU through an aviation plug and socket. An optical cable access box is provided in the intelligent circuit breaker stainless steel housing box. However, the existing 10 kV circuit breaker is only connected to the distribution terminal FTU through an aviation plug and does not integrate an Internet of Things module or edge computing unit. It cannot realize real-time data analysis and fault prediction, and it is difficult to meet the intelligent operation and maintenance requirements of the distribution network. On the other hand, manual disconnection of the disconnector is required while monitoring the current and voltage, which wastes manpower and poses certain operation and maintenance risks.
[0004] In view of this, we conducted in-depth research on the above issues, which led to the emergence of this case.
[0005] In response to the above problems, an innovative design was carried out based on the original 10kV circuit breaker. Summary of the Invention
