Description

Technical Field

[0001] The utility model relates to the technical field of circuit breakers, and in particular to a 4G intelligent Internet of Things circuit breaker. Background Art

[0002] A circuit breaker is a switch device that can close, carry and disconnect the current under normal circuit conditions and close, carry and disconnect the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, protect power lines and motors, etc. When they have serious overloads or short circuits and undervoltage faults, they can automatically cut off the circuit. Its function is equivalent to the combination of fuse switches and over-underheating relays. Moreover, it is generally not necessary to change parts after breaking the fault current. It has been widely used. Power distribution is an extremely important link in the generation, transmission and use of electricity. The power distribution system includes transformers and various high and low voltage electrical equipment, and low-voltage circuit breakers are a kind of electrical appliances with a large number of uses. Low-voltage circuit breakers, also known as automatic air switches, can be used to connect and disconnect load circuits, and can also be used to control motors that are not frequently started. Its function is equivalent to the sum of some or all functions of electrical appliances such as knife switches, overcurrent relays, undervoltage relays, thermal relays and leakage protectors. It is an important protective electrical appliance in low-voltage distribution networks.

[0003] Smart IoT circuit breaker refers to the remote control of the circuit by controlling the switch state of the circuit breaker through remote control signals. It is widely used in power distribution automation, industrial monitoring, smart home and other fields. The principle of the smart IoT circuit breaker is mainly to control the electromagnetic mechanism inside the circuit breaker through remote control signals to change its switch state. First, the remote control signal needs to pass through the signal conditioning unit to adjust the signal to adapt to the control circuit inside the circuit breaker. Secondly, the signal conditioning unit sends the adjusted signal to the relay unit, and the relay unit converts the control signal into mechanical movement to control the switch state of the circuit breaker through the electromagnet. It should be noted that the electromagnet here does not directly act on the circuit breaker switch, but transmits the power generated by the electromagnet to the switch through a complex transmission mechanism.
