Embodiment 1

[0047] A comprehensive detection system for high-voltage circuit breakers based on the ubiquitous power Internet of Things, including servers and local terminals, such as figure 1 As shown, the local end includes: a vibration detector 40, which detects the mechanical vibration of the circuit breaker 1; a magnetic field generator 20, which generates a changing magnetic field; a detection device 30, which is connected to the secondary plug-in of the circuit breaker 1, and detects the secondary circuit; the control unit 10. Connect the vibration detector 40, the magnetic field generator 20 and the detection device 30, and upload the local data to the server; the server calculates various parameters of the circuit breaker 1 through the obtained data. The high-voltage circuit breaker 1 will be affected by a certain magnetic field in the working state. Therefore, the present invention detects mechanical vibration and secondary circuits in a simulated magnetic field environment, which...

Embodiment 2

[0080] Such as image 3 As shown, this embodiment is roughly the same as Embodiment 1, the difference is that the fixed frame of the vibration detector 40 is a barrel-shaped hoop 7, one side of the barrel-shaped hoop 7 is connected to the measuring frame 2 through the rotating shaft 6, and the other side is The tightness of the barrel-shaped hoop 7 is adjusted by screws. Wherein the vertical support 3 is used to be placed on the ground when operating on the ground, and the barrel-shaped hoop 7 is used for use when measuring near positions such as utility poles.

[0081] Such as Figure 4 As shown, the barrel-shaped hoop is composed of several movable joints 8, and each movable joint 8 is connected to each other in the vertical direction. This design can increase structural strength.

[0082] The beneficial effects of this embodiment will not be described in detail.

[0083] Through the description of the above embodiments, those skilled in the art can understand that for t...

Description

technical field [0001] The invention relates to the field of performance detection of high-voltage circuit breakers, in particular to a comprehensive detection system and method for high-voltage circuit breakers based on the ubiquitous power Internet of Things. Background technique [0002] The circuit breaker is an important device in the high-voltage power grid, which mainly plays the role of control and protection equipment. With the increase of service time, some parts of the circuit breaker will continue to age or be damaged, such as the wear of the mechanical mechanism, the wear of the contacts, the failure of the opening and closing secondary mechanism, etc. These problems may lead to abnormal operation of the circuit breaker, and even affect the safe operation of the entire power grid. Therefore, it is very important to regularly check the performance of the circuit breaker and detect its operating status. However, there are many problems in the detection method of...
