[0041] The following will further illustrate the technical solutions of the present utility model in conjunction with the attached Figures 1 to 6 drawings and through specific embodiments.
[0042] The utility model provides a compatible magnetic induction sensor, which comprises a detection and installation component 1, a detection component 2, a hose clamp 3, two magnet adjustment components 4, a first magnet 5 and a second magnet 6; one end of the detection and installation component 1 is provided with a knife switch installation multi-stage structure, which is used for installing and connecting with the installation seat 100 of the knife switch, and the position between adjacent two levels of the knife switch installation multi-stage structure is adjustable; the other end of the detection and installation component 1 is provided with a detection and installation multi-stage structure, which is used for installing and connecting with the detection component 2, and the position between adjacent two levels of the detection and installation multi-stage structure is adjustable; the magnet adjustment component 4 is in a multi-stage structure, and the angular position between adjacent two levels is adjustable. The first magnet 5 is installed on one of the magnet adjustment components 4, and the second magnet 6 is installed on the other magnet adjustment component 4. The two magnet adjustment components 4 are installed on the hose clamp 3, and the hose clamp 3 is installed on the transmission column 200 of the knife switch and switches between the open position and the closed position therewith. When in the open position, the first magnet 5 is inductively connected with the detection component 2, and when in the closed position, the second magnet 6 is inductively connected with the detection component 2.
[0043] When using the magnetic induction sensor with the above structure, since the detection component 2 is arranged on the mounting seat 100 of the disconnecting switch and the first magnet 5 and the second magnet 6 are respectively arranged on the driving column 200 of the disconnecting switch, when the outdoor disconnecting switch is switched between the open and closed positions (states), the detection component 2 can detect and identify the first magnet 5 and the second magnet 6, so that the open and closed state information of the outdoor disconnecting switch can be obtained. For the neutral point disconnecting switch lightning arrester, since the pivot of the disconnecting switch is arranged on the driving column 200 below the lightning arrester, when the open and closed states of the disconnecting switch change, the induction component 2 on the mounting seat 100 is relatively fixed, while the positions of the first magnet 5 and the second magnet 6 on the driving column 200 relative to the induction component 2 will change, and the induction component 2 will detect different magnets, and then feedback the state of the neutral point disconnecting switch lightning arrester as a feedback signal. Further explanation, one end of the detection and installation component 1 connected to the mounting seat 100 is provided with a multi-stage structure for disconnecting switch installation. Through this multi-stage structure for disconnecting switch installation, the position and distance between the detection and installation component 1 and the mounting seat 100 can be adjusted, which is suitable for the installation and connection of different disconnecting switch mounting seats; in addition, one end of the detection and installation component 1 connected to the detection component 2 is provided with a multi-stage structure for detection and installation.

At the same time, since the magnet adjustment component 4 is also a multi-stage structure, the magnet adjustment component 4 can adjust its angle with the hose clamp 3 and the detection component 2 through its own multi-stage structure to ensure that the two magnets correspond to different states of the disconnecting switch. The utility model can be installed on disconnecting switches of different structural types through the detection and installation component 1 provided with a multi-stage structure for disconnecting switch installation. The detection component 2 is installed on the detection and installation component 1 through the multi-stage structure for detection and installation, and the two magnets are installed on the magnet adjustment component 4 with an adjustable angle. By respectively adjusting the detection and installation component 1 and the magnet adjustment component 4, the relative position, angle and distance between the detection component 2 and the two magnets can be adjusted to ensure the accuracy of detection and induction; and it can be applied to disconnecting switches / ground switches of different structures, improving the versatility, adaptability and compatibility of the utility model.

[0045] As Figure 3 and Figure 4 As shown, the detection and installation component 1 includes a mounting plate 11, a horizontal adjustment fixing plate 12, and a vertical adjustment fixing plate 13, where the horizontal adjustment fixing plate 12 and the vertical adjustment fixing plate 13 are the aforementioned detection and installation multi-stage structures, and this detection and installation multi-stage structure is provided on the side of the mounting plate 11 opposite to the knife switch mounting multi-stage structure; specifically, the lower part of the horizontal adjustment fixing plate 12 is installed and connected to the mounting plate 11, and the vertical adjustment fixing plate 13 is installed and connected to the upper part of the horizontal adjustment fixing plate 12, enabling the detection and installation multi-stage structure to have the function of multi-stage adjustment and installation. Further explanation, the horizontal adjustment fixing plate 12 includes a horizontal part 121 and a vertical part 122. The distance between the detection component 2 and the mounting seat 100 in the horizontal direction is adjusted by the specific installation position of the horizontal part 121 of the horizontal adjustment fixing plate 12 and the mounting plate 11 in the horizontal direction; the distance between the detection component 2 and the mounting seat 100 in the vertical direction is adjusted by the installation height of the vertical part 122 of the horizontal adjustment fixing plate 12 and the vertical adjustment fixing plate 13 in cooperation with each other, making the detection and installation component 2 more adjustable.
[0046] Further, one side of the mounting plate 11 is provided with a mounting recess 111. Both ends of the mounting recess 111 are mounting parts 112. The mounting parts 112 are provided with a plurality of fixing holes 1121. The plurality of fixing holes 1121 form a multi-level structure for mounting the knife switch. After the mounting recess 111 abuts against the mounting base 100, the mounting plate 11 is detachably mounted and fixed to the mounting base 100 by a fastener passing through the fixing holes 1121. On the other side of the mounting plate 11, there are several groups of horizontal adjustment holes 113.

[0047] One side of the mounting plate 11 is used for mounting and connecting with the mounting base 100 of the knife switch. Specifically, after the mounting recess 111 is clamped on the mounting base 100, a fastener such as a screw is used to pass through the fixing holes 1121 on the two ends of the mounting part 112, so that the mounting plate 11 is fixed on the mounting base 100.
[0048] For further explanation, on the other side of the mounting plate 11 away from the mounting part 112, there are several groups of horizontal adjustment holes 113, and the horizontal part 121 of the horizontal adjustment fixing plate 12 is provided with several mutually parallel horizontal mounting grooves 1211 corresponding to the horizontal adjustment holes 113. By using a fastener such as a screw rod to pass through the horizontal mounting grooves 1211 and the horizontal adjustment holes 113 in sequence, the mounting plate 11 and the horizontal adjustment fixing plate 12 are mounted and fixed. Since the several groups of horizontal adjustment holes 113 are arranged in an array along the length direction of the mounting plate 11, the distance between the horizontal adjustment fixing plate 12 and the mounting base 100 in the horizontal direction can be adjusted by adjusting the specific mounting positions of the horizontal mounting grooves 1211 and the horizontal adjustment holes 113, which is equivalent to adjusting the distance between the detection assembly 2 and the knife switch in the horizontal direction.
[0049] Further, the vertical part 122 is provided with several groups of vertical adjustment holes 1221. The several groups of vertical adjustment holes 1221 are arrayed along the extending direction of the vertical part 122.

[0050] The vertical portion 122 of the horizontal adjustment fixing plate 12 is provided with several groups of vertical adjustment holes 1221, and the vertical adjustment fixing plate 13 is provided with several threaded holes 131 corresponding to the vertical adjustment holes 1221. By using fasteners such as screws to sequentially pass through the vertical adjustment holes 1221 and the threaded holes 131, the horizontal adjustment fixing plate 12 and the vertical adjustment fixing plate 13 are installed and fixed. Since several groups of vertical adjustment holes 1221 are arranged in an array along the extending direction of the vertical portion 122, the height distance between the horizontal adjustment fixing plate 12 and the vertical adjustment fixing plate 13 in the vertical direction can be adjusted by adjusting the specific installation positions of the threaded holes 131 and the vertical adjustment holes 1221, making the detection and installation assembly 2 more adjustable.
[0051] Furthermore, the detection assembly 2 includes an induction box body 21 and two induction elements 22.

[0052] The two induction elements 22 are arranged vertically one above the other in the induction box body 21. Since the first magnet 5 and the second magnet 6 are installed on the hose clamp 3 through the magnet adjustment assembly 4, and the hose clamp 3 can rotate with the transmission column 200 to make the first magnet 5 inductively connected to the detection assembly 2 or the second magnet 6 inductively connected to the detection assembly 2. When two induction elements 22 are arranged in the detection assembly 2 to respectively correspond to the two (position) states of the knife switch, the first magnet 5 and the second magnet 6 can respectively correspond to the two induction elements 22, and the induction signals are used as the signal feedback of the open and closed states of the knife switch, making the accuracy and sensitivity of the magnetic induction sensor of the present application higher, reducing signal interference, and further improving the flexibility of the system.

On the other hand, since the induction element 22 is adjustably installed in the vertical installation groove 211, the specific position of the induction element 22 in the induction box body 21 can also be adjusted to make the first magnet 5 / second magnet 6 correspond to the two induction elements 22 one by one.
[0055] The front and both sides of the induction box body 21 are provided with waterproof rubber pads 23, so that the overall installation of the induction box body 21 reaches the IP55 waterproof level.

By using fasteners such as screws to pass through the adjustment arc groove 4311 and the magnet plate adjustment holes, the magnet fixing plate 44 is fixedly installed with the angle adjustment plate 43, so as to adjust the horizontal distance and / or height distance between the first magnet 5 / second magnet 6 and the transmission column 200 through the adjustment arc groove 4311, which is equivalent to adjusting the relative position between the first magnet 5 / second magnet 6 and the detection component 2 (induction element 22).
