Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Please refer to the attached Figure 1-5 In one embodiment of the present invention, a magnetic induction monitoring device for opening and closing of switches comprises an installation component 10, a closing magnetic steel component 20, an opening magnetic steel component 30 and a magnetic induction sensor device 40. First of all, it should be noted that, unlike the prior art, it is difficult for technicians to accurately know whether the disconnector is faulty before maintenance. Sometimes, when the disconnector is opening and closing, there will be external factors such as wind force, which may cause the opening and closing of the disconnector to be out of place and offset, but in fact the disconnector is not faulty, which affects the judgment of the technicians and leads to repeated maintenance, which is time-consuming and labor-intensive. Frequent occurrence increases the labor level of the technicians. The present application solves the above-mentioned defects in the prior art by providing a magnetic induction monitoring device for opening and closing of switches, as follows:

[0037] The mounting assembly 10 is used to be connected to the bearing seat of the isolating switch body 50, the closing magnetic steel assembly 20 and the opening magnetic steel assembly 30 are both connected to the mounting assembly 10 and are both arranged telescopically in the vertical direction, and the closing magnetic steel assembly 20 and the opening magnetic steel assembly 30 are arranged at intervals along the circumference of the mounting assembly 10; the magnetic induction sensor device 40 includes a magnetic induction sensor body 410, a closing reed switch 420 and an opening reed switch 430, the magnetic induction sensor body 410 is used to be installed on the switch base 550, the closing magnetic steel assembly 20 and the opening magnetic steel assembly 30 are both arranged at intervals above the magnetic induction sensor body 410, the closing reed switch 420 and the opening reed switch 430 are both built in the magnetic induction sensor body 410, and the closing reed switch 420 and the opening reed switch 430 are arranged at intervals.

[0038] Specifically, the magnetic induction monitoring device for closing and opening the switch in the present application includes an installation component 10, a closing magnetic steel component 20, an opening magnetic steel component 30 and a magnetic induction sensor device 40. The installation component 10 is used for installing the closing magnetic steel component 20 and the opening magnetic steel component 30, and is connected to the bearing seat to connect the closing magnetic steel component 20 and the opening magnetic steel component 30 to the bearing seat, so that they can rotate with the bearing seat. The installation component 10 can be in the form of an arc ring to facilitate installation on the bearing seat, and can be conveniently installed by bolt connection. After tightening, it can rotate with the bearing seat. For details, please refer to the attached Figure 3 The closing magnetic steel assembly 20 and the opening magnetic steel assembly 30 are used to cooperate with the magnetic induction sensor device 40 respectively, so as to send out a closing signal and an opening signal respectively when the closing and opening positions are in place, so that the technical personnel can know the fault condition of the disconnector. It can be understood that the closing magnetic steel assembly 20 and the opening magnetic steel assembly 30 are arranged at intervals along the circumference of the mounting assembly 10, so that when the mounting assembly 10 follows the circular rotation of the bearing seat itself, it also follows the circular rotation, so that the closing magnetic steel assembly 20 and the opening magnetic steel assembly 30 arranged at intervals along the circumference can both rotate to the magnetic induction sensor device 40.

[0039] Among them, the magnetic induction sensor device 40 includes a magnetic induction sensor body 410, a closing reed switch 420 and an opening reed switch 430. The magnetic induction sensor body 410 is used to transmit signals after power is turned on, and the reed switch is usually composed of two soft magnetic metal reeds. When an external magnetic field approaches, the two reeds are magnetized to generate magnetic fields of different polarities. When the magnetic field strength is sufficient, the two reeds will be attracted together to make the circuit conductive; when the external magnetic field moves away, the reeds are gradually demagnetized and disconnected, and the circuit is disconnected. Therefore, based on this principle, the closing reed switch 420 and the opening reed switch 430 built into the magnetic induction sensor body 410 need to be arranged at intervals through the cooperation of the magnetic steel assembly and the reed switch to avoid interference with each other. In this way, when the closing magnetic steel assembly 20 moves with the bearing seat When it rotates to just above the closing reed switch 420, the magnetism of the closing magnetic steel assembly 20 causes the closing reed switch 420 to be attracted, and at this time the magnetic signal is conducted and converted into an electrical signal, and the magnetic induction sensor body 410 sends a closing state signal to ensure that the closing is in place; similarly, when the opening magnetic steel assembly 30 rotates with the bearing seat to just above the opening reed switch 430, the magnetism of the opening magnetic steel assembly 30 causes the opening reed switch 430 to be attracted, and at this time the magnetic signal is conducted and converted into an electrical signal, and the magnetic induction sensor body 410 sends an opening state signal to ensure that the opening is in place, so that in this way it can be ensured at all times whether the isolating switch is in place for opening and closing, and normal operation can be guaranteed, so as to distinguish whether there is a fault, and then decide whether to perform maintenance, so as to reduce the number of incorrect maintenance by maintenance personnel and improve efficiency.

[0040] Preferably, the closing magnetic steel assembly 20 and the opening magnetic steel assembly 30 are both vertically telescopically arranged, so that the distance between the magnetic steel and the magnetic induction sensor body 410 can be adaptively adjusted, that is, the attraction range of the magnetic field can be adjusted to avoid the weakening of magnetism after a long period of use, resulting in an unclear magnetic attraction effect. At this time, the spacing 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 telescopic adjustment to ensure the magnetic attraction effect, thereby ensuring that the device can operate normally, thereby extending the service life and reducing replacement costs.

[0041] As a preferred embodiment of the present invention, the closing magnetic steel assembly 20 includes a closing magnetic steel bracket 210, a closing support plate 220 and a closing magnetic steel 230, wherein the closing support plate 220 is arranged in a bent shape, and the closing support plate 220 includes a first vertical adjustment portion 221 and a first horizontal placement portion 222, wherein the top end of the closing magnetic steel bracket 210 is connected to the mounting assembly 10, the first vertical adjustment portion 221 is vertically movably and adjustably connected to the bottom end of the closing magnetic steel bracket 210, the first horizontal placement portion 222 is cantilevered and connected to the bottom end of the first vertical adjustment portion 221, and the closing magnetic steel 230 is connected to the first horizontal placement portion 222.

[0042] It should be noted that the closing magnetic steel bracket 210 is used for the installation of the closing support plate 220, and its top end is connected to the mounting assembly 10, and the closing support plate 220 is used for the installation of the closing magnetic steel 230, so as to cooperate with the connection of the closing magnetic steel 230 to the mounting assembly 10. The closing support plate 220 is arranged in a bent shape, so that the vertical part is connected to the closing magnetic steel bracket 210 in a vertically movable and adjustable manner, which is convenient for adjusting the magnetic attraction range, and the horizontal part is for placing the closing magnetic steel 230, so it includes a first vertical adjustment part 221 and a first horizontal placement part 222, and the first vertical adjustment part 221 is used to adjust the connection position with the closing magnetic steel bracket 210 along the vertical movement, and the closing magnetic steel 230 is connected to the first horizontal placement part 222. It can be understood that the first horizontal placement part 222 is arranged above the magnetic induction sensor body 410 along the vertical interval, and it can be within the magnetic attraction range.

[0043] As a preferred embodiment of the present invention, the opening gate magnetic steel assembly 30 includes a opening gate magnetic steel bracket 310, a opening gate support plate 320 and a opening gate magnetic steel 330, the opening gate support plate 320 is arranged in a bent shape, and the opening gate support plate 320 includes a second vertical adjustment portion 321 and a second horizontal placement portion 322, wherein the top end of the opening gate magnetic steel bracket 310 is connected to the mounting assembly 10, the second vertical adjustment portion 321 is vertically movably and adjustably connected to the bottom end of the opening gate magnetic steel bracket 310, the second horizontal placement portion 322 is cantilevered and connected to the bottom end of the second vertical adjustment portion 321, and the opening gate magnetic steel 330 is connected to the second horizontal placement portion 322.

[0044] It should be understood that, similar to the closing magnetic steel bracket 210 and the closing support plate 220, the opening magnetic steel bracket 310 adopts the same structural form as the closing magnetic steel bracket 210 and the closing support plate 220, so as to facilitate processing and installation together, and the spacing distance between the magnetic induction sensor body 410 is consistent, which is convenient for adjustment to ensure consistent magnetic attraction effect. The second vertical adjustment part 321 is used for vertical telescopic adjustment, and the second horizontal placement part 322 is used for connection of the opening magnetic steel 330.

[0046] It is worth noting that the vertical adjustment effect is achieved by respectively opening the first long hole 223 and the second long hole 211 on the first vertical adjustment portion 221 and the closing magnetic steel bracket 210. Therefore, the first long hole 223 and the second long hole 211 are both extended vertically. After adjusting the position of the closing support plate 220, the first limiting bolt 240 and the first limiting nut 250 can be used to fix it.

[0048] It can be understood that, similar to the first vertical adjustment part 221, the second vertical adjustment part 321 is also adjusted by opening a third long hole 323 to cooperate with the fourth long hole 311 on the gate magnetic steel bracket 310, and it is consistent during processing and production, and batch processing of parts is convenient.

[0050] It should be noted that the gasket can reduce the pressure of the nut on the magnetic steel bracket, reduce local stress concentration, avoid damage to the bracket due to excessive force, and enhance the stability of the connection. Therefore, the first limiting nut 250 and the second limiting nut 350 are each respectively provided with a first gasket 260 and a second gasket 360 when they are matched and connected.

[0051] Further, the number of the first long hole 223, the second long hole 211, the third long hole 323 and the fourth long hole 311 are all two.

[0052] It should be understood that the number of the long holes can be determined according to the length of the vertical adjustment portion. In the present application, as a preferred embodiment, the number is set to two, and those skilled in the art can choose according to actual needs.

Maintaining the spacing setting can not affect the closing and opening of the switch with the magnetic attraction effect. However, when the magnetic attraction effect is not obvious, the spacing distance can also be set to 0, that is, the magnet is set to fit the top of the magnetic induction sensor body 410. Technical personnel in this field can set it according to actual conditions.

[0055] Furthermore, the mounting assembly 10 is connected to the bearing seat by bolts.

[0056] It should be noted that the installation assembly 10 can be easily disassembled, assembled and replaced later by means of bolt connection.
