Description

Technical Field

[0002] Universal air circuit breaker is an electrical appliance that has both manual switch function and automatic protection against loss of pressure, undervoltage, overload, and short circuit. It can be used to distribute electric energy, start asynchronous motors infrequently, and protect power lines and motors. It can automatically cut off the circuit when they have serious overloads or short circuits and undervoltage faults. Its function is equivalent to the combination of fuse switches and over-underheating relays, and generally does not require the replacement of parts after breaking the fault current. It has been widely used. With the continuous improvement of the requirements of the power system, the performance requirements for circuit protection switches are getting higher and higher. Miniaturization, high performance, modularization, and high reliability are the development direction of circuit breakers at this stage.

[0003] In order to improve the intelligence, automation and information level of frame circuit breakers, the intelligent controller combines the current development trend of intelligent controllers for low-voltage circuit breakers at home and abroad, absorbs advanced experience of intelligent controllers at home and abroad, and uses high-performance microprocessors and high-precision data acquisition technology to research and develop intelligent controllers suitable for frame circuit breakers.

[0004] The current controller is connected directly to the wire terminals of the components between the frame circuit breaker body through the terminals on the controller.

If the wires are crushed on the production line, the workers need to disassemble and reassemble them, which not only wastes time, but also produces some defective materials. In the future, when customers replace the controller or perform after-sales maintenance, the operation space is small, making it difficult to operate and inconvenient to install.
