The present application is set to a kind of closing and opening magnetic induction monitoring device to solve the above defects in prior art, as follows:

[0037] The installation component 10 is used to be connected to the bearing seat of disconnecting switch body 50, the closing magnetic steel component 20 and the opening magnetic steel component 30 are connected to the installation component 10 and are arranged vertically and can be extended, the closing magnetic steel component 20 and the opening magnetic steel component 30 are arranged along the circumference of the installation component 10; The magnetic induction sensing device 40 includes magnetic induction sensor body 410, closing reed tube 420 and opening reed tube 430, the magnetic induction sensor body 410 is used to be installed on switch base 550, the closing magnetic steel component 20 and the opening magnetic steel component 30 are arranged above the magnetic induction sensor body 410, the closing reed tube 420 and the opening reed tube 430 are built-in in the magnetic induction sensor body 410, and the closing reed tube 420 and the opening reed tube 430 are arranged.

[0038] Specifically, the closing and opening magnetic induction monitoring device in the application comprises a mounting assembly 10, a closing magnetic steel assembly 20, an opening magnetic steel assembly 30 and a magnetic induction sensing device 40. The mounting assembly 10 is used for mounting the closing magnetic steel assembly 20 and the opening magnetic steel assembly 30, and is connected with a bearing seat to connect the closing magnetic steel assembly 20 and the opening magnetic steel assembly 30 to the bearing seat, so that the closing magnetic steel assembly 20 and the opening magnetic steel assembly 30 can rotate with the bearing seat. The mounting assembly 10 can adopt the form of an arc-shaped ring to facilitate installation on the bearing seat and is conveniently installed through bolt connection. After fastening, the mounting assembly 10 can rotate with the bearing seat. For details, please refer to the accompanying drawings Figure 3 The closing magnetic steel assembly 20 and the opening magnetic steel assembly 30 are used for cooperating with the magnetic induction sensing device 40 respectively to respectively send a closing signal and an opening signal when closing and opening are in place, so that the technical personnel can know the fault condition of the disconnecting switch. It can be understood that the closing magnetic steel assembly 20 and the opening magnetic steel assembly 30 are arranged along the circumference of the mounting assembly 10 to facilitate the mounting assembly 10 to rotate along the circumference when the bearing seat rotates along the circumference. In this way, the closing magnetic steel assembly 20 and the opening magnetic steel assembly 30 arranged along the circumference can rotate to the magnetic induction sensing device 40.

[0039] The magnetic induction sensing device 40 comprises a magnetic induction sensor body 410, a closing reed tube 420 and an opening reed tube 430. The magnetic induction sensor body 410 is used for transmitting a signal after being energized. The reed tube is usually composed of two soft magnetic metal reed pieces. When an external magnetic field is close, the two reed pieces are magnetized to generate magnetic fields with different polarities. When the magnetic field strength is sufficient, the two reed pieces are attracted together to make the circuit conductive. When the external magnetic field is far away, the reed pieces gradually demagnetize and disconnect, and the circuit is disconnected. Therefore, according to the principle, the closing reed tube 420 and the opening reed tube 430 built in the magnetic induction sensor body 410 need to be arranged at intervals to avoid interference between each other. In this way, when the closing magnetic steel assembly 20 rotates with the bearing seat to be directly above the closing reed tube 420, the magnetism of the closing magnetic steel assembly 20 attracts the closing reed tube 420.

Similarly, when the opening magnetic steel assembly 30 rotates with the bearing seat to be directly above the opening reed tube 430, the magnetism of the opening magnetic steel assembly 30 attracts the opening reed tube 430. At this time, the magnetic signal conduction is converted into an electric signal, the magnetic induction sensor body 410 sends an opening state signal to ensure that the opening is in place. In this way, the closing and opening of the disconnecting switch can be ensured at any time to ensure normal operation and to determine whether to repair to reduce the number of incorrect repairs by repair personnel and improve efficiency.

[0040] Preferably, the closing magnetic steel assembly 20 and the opening magnetic steel assembly 30 are vertically telescopic, so that the distance between the magnetic steel and the magnetic induction sensor body 410 can be adjusted, that is, the attraction range of the magnetic field is adjusted, so that after a long period of use, the magnetic property is not weakened, and the magnetic attraction effect is not obvious. At this time, the interval distance between the closing magnetic steel assembly 20 and the opening magnetic steel assembly 30 and the magnetic induction sensor body 410 can be adjusted by telescoping to ensure the magnetic attraction effect, thereby ensuring that the device can operate normally, prolonging the service life and reducing replacement costs.
