[0020] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention. Example

[0021] A disconnector adjustment device comprises a frame 4, a disconnecting block 1, a control assembly 3 and an actuating arm 2, wherein the disconnecting block 1 is slidably matched with the frame 4, the actuating arm 2 is matched with the disconnecting block 1 via a hook structure 13, the disconnecting block 1 is matched with a first spring 5, the control assembly 3 is rotationally matched with the actuating arm 2 so that the hook structure 13 is disengaged, the control assembly 3 is slidably matched with the frame 4, and the sliding direction of the control assembly 3 is perpendicular to the direction of the rotation axis of the actuating arm 2.

[0022] In order to realize the active disconnecting function of the backup protection breaker of the surge protector, the backup protection breaker of the surge protector now controls the action of the electromagnetic release through the current transformer, and the action side of the electromagnetic release cooperates with the moving contact of the spacing structure arranged on the grounding circuit through the linkage mechanism. The action side of the electromagnetic release moves the moving contact to be separated from the grounding circuit through the linkage mechanism, thereby disconnecting the grounding circuit.

[0023] In order to solve the problem that the electromagnetic release is a relatively independent integrated component, and the direction and stroke of its action end are fixed, it needs to be linked with the breaking block 1 through a linkage mechanism. The electromagnetic release and the linkage mechanism occupy a large space in the surge protector, which is not conducive to the miniaturization of the product. The control component 3 in this scheme has the function of a general electromagnetic release, and the control component 3 rotates with the action arm 2. The action arm 2 has the function of the action end of the general electromagnetic release. Compared with the existing scheme, the action end of the electromagnetic release needs to be linked with the breaking block 1 through a linkage mechanism. The action arm 2 in this scheme directly cooperates with the breaking block 1 through the hook structure 13. The control component 3 rotates with the action arm 2, so that the action arm 2 rotates until the hook structure 13 between it and the breaking block 1 is disengaged, and the breaking block 1 moves to be separated from the grounding circuit under the action of the first spring 5, thereby disconnecting the grounding circuit.

[0024] In order to achieve the miniaturization of the active disconnecting functional structure, the control component 3 and the action arm 2 are rotated together to realize the functions of the action end and the linkage mechanism of the general electromagnetic release. The action arm 2 forms a lever structure, which replaces the existing linkage mechanism to realize the problem of fixing the direction and stroke of the action end of the general electromagnetic release. However, the arc motion trajectory during its rotation can easily cause the hook structure 13 between it and the breaking block 1 to be stuck, resulting in the inability to separate the action arm 2 and the breaking block 1. To solve this problem, the control component 3 in this scheme is slidably matched with the frame 4, and the sliding direction of the control component 3 is perpendicular to the direction of the rotation axis of the action arm 2, so as to facilitate the position adjustment of the control component 3 and the action arm 2. The relative position of the breaking block 1 remains unchanged, and the matching relationship of the hook structure 13 between the action arm 2 and the breaking block 1 is changed to obtain the optimal matching position of the hook structure 13 between the action arm 2 and the breaking block 1. The breaker adjustment device in the present scheme can realize the rapid adjustment of the hook structure 13 between the action arm 2 and the breaking block 1, so as to solve the problem of the hook structure 13 getting stuck before the device is finalized, and the device can be retained after the device is finalized so as to facilitate adjustment according to the dimensional tolerances of the various components of the backup protection breaker during product assembly, so as to avoid the relative position deviation between the action arm 2 and the breaking block 1 after assembly due to the dimensional tolerances of the various components, and the hook structure 13 is easily stuck, resulting in the risk of failure of the backup protection function.

[0025] In an optional embodiment, the frame 4 cooperates with the control component 3 through a sliding structure, and the control component 3 is arranged around the hook structure 13 .

[0026] The sliding structure is an arc structure, and the arc structure is arranged around the hook structure 13 , so that the control component 3 and the action arm 2 can rotate around the hook structure 13 .

[0027] Specifically, the action arm 2 rotates in coordination with the control component 3, that is, the action arm 2 has a rotation axis, and the hook structure 13 on the action arm 2 can rotate with the action arm 2 around the rotation axis to cooperate with or disengage from the structure on the dividing block 1. Due to the existence of the sliding structure, the rotation axis of the action arm 2 rotates around the hook structure 13, thereby adjusting the coordination between the action arm 2 and the dividing block 1 to avoid the hook structure 13 from getting stuck.

[0028] In an optional embodiment, the hook body structure 13 includes a hook body portion arranged on the action arm 2 and a groove body portion arranged on the dividing block 1, the frame body 4 includes two split bodies that can be enclosed to form a cavity, the control component 3 is located in the cavity, the control component 3 includes a bracket 10 and an additional component 8 located on both sides of the bracket 10, the sliding structure includes a second sliding portion 7 respectively arranged on the two split bodies and a first sliding portion 6 respectively arranged on the two additional components 8, the two second sliding portions 7 are located in the cavity and arranged opposite to each other, the first sliding portion 6 corresponds to the second sliding portion 7, the second sliding portion 7 is arranged around the groove body portion, and the two split bodies are against the control component 3.

[0029] The hook body is arranged at the end of the action arm 2, and the hook body can extend into the slot body on the breaking block 1 as the action arm 2 rotates, constraining the breaking block 1 to prevent the breaking block 1 from moving under the action of the first spring 5. The action arm 2 can rotate around the slot body along with the action arm 2 and the control assembly 3, so that the hook body at the end of the action arm 2 can adjust the angle of extending into the slot body, preventing the hook body from getting stuck with the slot body when the action arm 2 rotates around its rotation axis to extend out of the slot body.

[0030] The fixation between the frame 4 and the control component 3 is achieved by clamping the control component 3 by the split body. Specifically, the split body is enclosed to form a cavity, and the control component 3 is located in the cavity. The control component 3 includes a bracket 10 that cooperates with the action arm 2 and an additional part 8 located on both sides of the bracket 10. A second sliding part 7 extending along an arc is provided on the side of the split body facing the cavity, and a first sliding part 6 extending along an arc is provided on the side of the additional part 8 corresponding to the split body. When the two split bodies are buckled, the two groups of first sliding parts 6 and second sliding parts 7 cooperate respectively. When the two split bodies are not buckled, the control component 3 is matched with one of the split bodies, and the position is adjusted to the matching of the hook body and the groove body, and then the other split body is buckled, and the fixation is achieved by the mutual extrusion of the two split bodies and the control component 3.

[0031] Alternatively, the split body and the control component 3 are fixed by screws, and screw holes are provided at corresponding positions of the split body and the control component 3. When the two split bodies are not buckled together, the control component 3 is matched with one of the split bodies, and the position is adjusted so that the hook body and the groove body are matched, and then the other split body is buckled together, and finally the screws are inserted into the screw holes to achieve fixation.

[0032] In an optional embodiment, the control component 3 includes a bracket 10, a coil assembly 12 and a second spring 9. The bracket 10 is a semi-enclosed structure with an opening on one side. The bracket 10 has a first end and a second end on both sides near the opening, respectively. The action arm 2 has relative hook ends and rotating ends, respectively. The action arm 2 near the rotating end rotates with the bracket 10 near the second end, and a second spring 9 is provided between the action arm 2 and the bracket 10. The action arm 2 near the hook end can be offset with the bracket 10 near the first end under the action of the magnetic field of the permanent magnet 11); the coil assembly 12 is mounted on the bracket 10, and the coil assembly 12 is connected to the secondary side of the transformer mounted on the grounding circuit of the surge protector.

[0033] The bracket 10 is C-shaped, with an opening on one side, and the two sides of the opening are respectively a first end and a second end, the first end and the second end are respectively against the action arm 2, wherein the second end can form a rotational match with the rotating end of the action arm 2, and the first end adsorbs the action arm 2 under the action of the magnetic field to make them against each other. The hook body part at the hook body end of the action arm 2 cooperates with the groove body part on the breaking block 1, so that the action arm 2 constrains the breaking block 1 along its moving direction.

[0034] Preferably, the abutment position between the first end of the bracket 10 and the action arm 2 is located between the hook end and the rotating end of the action arm 2 .

[0035] The coil assembly 12 includes a sleeve and a wire wound on the sleeve. The sleeve is sleeved on the bracket 10 between the first end and the second end. The wire is connected to the secondary side of the current transformer. The surge protector in this scheme is used for an AC circuit. Therefore, the direction of the magnetic field generated by the coil assembly 12 changes with the current. When the direction of the magnetic field is opposite to the direction of the magnetic field generated by the permanent magnet 11), the magnetic field generated by the coil assembly 12 offsets the magnetic field generated by the permanent magnet 11) or the two offset and weaken until the suction force on the action arm 2 is less than the elastic force of the second spring 9, so that the action arm 2 rotates under the action of the second spring 9.

[0036] In an optional embodiment, the bracket 10 is provided with a slot, and the permanent magnet 11) is embedded in the slot.

[0037] In an optional embodiment, a second spring 9 is provided on the action arm 2 near the rotation axis and connected to the control assembly 3 .

[0038] In an optional embodiment, the end of the second end of the bracket 10 abuts against the action arm 2 near the second end, and the hook end and the rotating end of the action arm 2 are respectively located on both sides of the second end of the bracket 10, so that the hook end of the action arm 2 can be rotated to the first end close to the bracket 10, and one end of the second spring 9 is connected to the action arm 2 between the rotating end and the second end of the bracket 10.

[0039] The end of the second end of the bracket 10 forms a fulcrum structure, which abuts against the action arm 2. The area where the action arm 2 abuts against the first end is located on one side of the end of the second end of the bracket 10. The rotating end of the action arm 2 extends from the other side of the end of the second end of the bracket 10. One end of the second spring 9 is connected to the action arm 2 between the rotating end and the second end of the bracket 10, so that the action arm 2 and the end of the second end of the bracket 10 cooperate to form a seesaw structure. The hook end of the action arm 2 and the area abutting against the first end of the bracket 10 are located on one side of the second end of the bracket 10, and the second spring 9 and the rotating end of the action arm 2 are located on the other side of the second end of the bracket 10. When the action arm 2 abuts against the first end of the bracket 10 The second spring 9 is in a stretched state, and the magnetic attraction force and the elastic force of the second spring 9 are respectively on both sides of the second end of the bracket 10, so that the end of the action arm 2 and the second end of the bracket 10 are pressed tightly. When the magnetic field generated by the coil assembly 12 offsets the magnetic field generated by the permanent magnet 11) or the two offset and weaken to the point where the attraction force on the action arm 2 is less than the elastic force of the second spring 9, the second spring 9 pulls the rotating end of the action arm 2 to make the action arm 2 rotate around the second end of the bracket 10, so that the action arm 2 is separated from the first end of the bracket 10, and the hook end of the action arm 2 is also separated from the breaking block 1. On the premise of achieving the rotational coordination between the action arm 2 and the bracket 10, the rotation structure is simplified to avoid the introduction of a rotating shaft or other structural parts.

[0041] The function of the clamping member is to constrain the action arm 2 to prevent the action arm 2 from moving along the axial direction of rotation.

[0042] In an optional embodiment, a corresponding position of the end surface of the split body toward the additional member 8 is protruded to form the second sliding portion 7, and a corresponding position of the end surface of the additional member 8 toward the split body is recessed to form the first sliding portion 6.
