At this time, the current in the circuit will be guided inside the single-chip microcomputer device 4 through the wire 5, providing working power for the single-chip microcomputer device 4 and enabling the sensors equipped inside the single-chip microcomputer device 4 to operate. At the same time, the wire 5 conducts the current into the two input resistors 6. After passing through the inside of the input resistors 6, it drives the input diode 7 to emit light. During the operation of the device, the input diode 7 always remains lit, facilitating personnel to directly observe the state of the vacuum circuit breaker.

[0029] In a further preferred embodiment of the present utility model, as Figure 3 - Figure 4 and Figure 6 shown, the power-off structure is provided with a mechanical box 8, and a contact 9 is provided on one side of the mechanical box 8. A sealing cylinder 10 is provided outside the contact 9, and one end of the sealing cylinder 10 is fixedly connected to one side of the mechanical box 8.

Both ends of the sealing cylinder 10 are sealed with the mechanical box 8 and the fixed box 11 respectively, and the inside of the sealing cylinder 10 is a vacuum environment.

[0030] The single-chip microcomputer device 4 integrates a variety of sensors internally, which are respectively: a current sensor for measuring the current value in the circuit; a voltage sensor for measuring the voltage value in the circuit to help confirm the circuit state and voltage stability; a temperature sensor for measuring the temperature of the environment or the device. The single-chip microcomputer device 4 integrates diverse sensors and an Internet of Things system internally. The data collected by various sensors will be transmitted to the cloud through the Internet of Things system. The data during the device operation will be compared with other normal data. If an abnormality occurs, the Internet of Things system will push the abnormal data to the terminal device. Personnel can monitor the real-time working state of the vacuum circuit breaker to detect and troubleshoot possible faults in a timely manner. When abnormal data continues to be generated for a set time and the device is still in the operating state, the device will determine that there is a fault in the circuit. At this time, the single-chip microcomputer device 4 will drive the opening and closing operation to separate it from the travel switch, thereby opening the circuit.

[0032] The output diode 14 is located in the opposite direction to the input diode 7, and the electrode 15 connected to it through the wire 5 serves as the output end of the device. During the operation of the device, the output diode 14 will continuously light up. On the contrary, if there is a short circuit or open circuit inside the device, since the current cannot directly pass through the wire 5 to the output diode 14, at this time the output diode 14 will go out. Through the cooperative action of the output diode 14 and the input diode 7, it is convenient for personnel to directly observe the operating state of the vacuum circuit breaker.
