[0002] A circuit breaker is a switch device that can close, carry and disconnect current under normal circuit conditions and close, carry and disconnect 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. The boundary between high and low voltage is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances.

[0003] Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. They can automatically cut off circuits when serious overloads, short circuits, undervoltage faults, etc. occur. Their functions are equivalent to the combination of fuse switches and over- and under-temperature relays, and generally no parts need to be changed after disconnecting the fault current. They have been widely used.

[0004] However, the existing circuit breakers have poor heat dissipation performance. When working for a long time in a high temperature environment, the service life of their parts may be affected due to their height. Therefore, they do not meet the existing needs. We propose a circuit breaker with a heat dissipation structure. Utility Model Content

During the process of flowing inside the water source circulating flow pipe 2, the water will enter the interior of the externally threaded pipe 7 communicated with the interior of the water source circulating flow pipe 2, and enter the interior of the water source transfer groove 14 along the externally threaded pipe 7. The water entering the water source transfer groove 14 will pass through the water The source flow pipe 6 enters the interior of the heat dissipation water source storage tank 5 that is in contact with the circuit breaker 1, and is discharged from the water source flow pipe 6 connected to the lower end surface of the heat dissipation water source storage tank 5, and enters the interior of the water source transfer groove 14 that communicates with the interior of the water source flow pipe 6 along the water source flow pipe 6, and passes through the water source transfer groove 14 to enter the interior of the external threaded pipe 7 located below the circuit breaker 1 and finally flows back to the interior of the water source circulation flow pipe 2.

[0026] The outer surface of the externally threaded tube 7 is sleeved with a fixing sleeve 11 matching its external thread, and the fixing sleeve 11 is connected to the connecting head 13 through a roller bearing; when the circuit breaker 1 needs to be replaced, the fixing sleeve 11 is rotated, and the rotating fixing sleeve 11 can move up and down through the transmission of the external thread of the externally threaded tube 7. At this time, the fixing sleeve 11 is moved in the opposite direction of the circuit breaker 1. During the movement of the fixing sleeve 11, the connecting head 13 connected to it through a roller bearing and the flow diverter 9 fixed to the connecting head 13 will move together.
