New materials, new processes, innovative thermal release mechanism for a hundred years

05 Nov,2024

In today's constantly evolving power protection technology, circuit breakers, as key safety protection devices, have a direct impact on the stability of the power system and the safety of users' lives and property. The traditional thermal bimetallic strip tripping mechanism has been used in the electrical industry for nearly a century, but with the rapid development of new energy, low-carbon industry, and energy IoT, its limitations are becoming increasingly prominent. Therefore, Jingsi Intelligent has successfully developed and applied for an innovative technology patent based on the characteristics of soft magnetic materials, relying on its deep research and development strength and continuous technological accumulation in the field of circuit breakers. This innovative achievement not only changes the design framework of traditional thermal double metal trip mechanisms, but also brings revolutionary breakthroughs to the field of circuit breakers with its unique advantages.
This patent from Jingsi Intelligent proposes a new design scheme for thermal trip mechanism, which relies on the unique physical properties of soft magnetic materials to achieve thermal trip function as a backup overload protection for intelligent circuit breakers. The internal components of the organization include temperature sensing power components, connecting components, and fasteners installed inside the circuit breaker housing. The temperature sensing power component can sense temperature changes in the circuit in real time and convert these changes into tripping power through connecting components. When the temperature reaches the set threshold, the release component will quickly act to cut off the circuit, thereby protecting electrical equipment from the impact of overload faults.


Institutional optimization, small size, big impact
The traditional hot double metal release mechanism often requires a large operating space to ensure the normal deformation and release of the bimetallic sheet, but this patented design by Jingsi Intelligent cleverly abandons this limitation. By optimizing the internal structure and material selection, the mechanism has achieved a significant reduction in volume, providing more flexibility and space utilization for the overall design of circuit breakers, and meeting the needs of modern electrical equipment for miniaturization and integration.
 
Intelligent control simplifies the thermal adjustment function
Jingsi's patented technology not only lies in hardware innovation, but also integrates the concept of intelligent control. The thermal trip mechanism combines electronic overload protection and soft magnetic material thermal trip mechanism to form a dual overload protection system. Under normal working conditions, the electronic protection system prioritizes response to achieve fast and accurate overload monitoring and control; When the electronic system fails, the soft magnetic material thermal release mechanism serves as a backup guarantee and can immediately intervene to ensure circuit safety. This dual protection mechanism not only improves the overall reliability of the circuit breaker, but also greatly simplifies the complexity of traditional thermal regulation functions and reduces maintenance costs.
 
Strong release force ensures quick response
Different from the limited release force generated by the deformation of bimetallic sheets, Jingsi Intelligent's patented technology optimizes the release power structure and directly drives the release action using the elastic force of the release spring, generating a release force far greater than the force provided by traditional bimetallic sheet deformation. This design ensures that the circuit breaker can quickly and accurately cut off the circuit in emergency situations, effectively preventing safety accidents such as electrical fires. At the same time, this thermal trip mechanism also has higher mechanical strength and stability, which enables the trip mechanism to maintain excellent performance in long-term use and is more suitable for circuit breakers with linkage slider mechanisms.
This invention patent of Jingsi Intelligence is another example of Jingsi adhering to the core value concept of "customer first, daring to be the first", insisting on the original spirit guided by customer needs, constantly exploring and breaking through, and creating cross-border innovations. On the path of future development, Jingsi will firmly adhere to its original intention and continue to innovate and create in the Pasteur quadrant as always. We are well aware that only by constantly standing at the forefront of technology and daring to explore the unknown, can we provide customers with safer, more efficient, and intelligent electrical solutions.
