Description

Technical Field

[0001] This utility model belongs to the field of surge protector technology, and more specifically, it relates to a surge protector tripping mechanism. Background Technology

[0002] Surges are a factor that affects power stability. They are usually caused by instantaneous changes in voltage and current, such as direct lightning strikes, lightning induction, or switching operations, capacitor and inductor switching within the power grid. They can easily damage electronic equipment. Therefore, surge protectors are needed to protect against surge hazards.

[0003] By monitoring voltage and current fluctuations in the line, the connection of the line is disconnected through a tripping mechanism when a surge occurs, thereby protecting the downstream equipment. For example, Chinese utility model patent No. 202020177271.5 provides a tripping mechanism. This mechanism, through the arrangement of a drive mechanism, a tripping element, a hanging ring, and a current transformer, monitors voltage and current fluctuations in the line through the current transformer during use. When a surge occurs, the drive mechanism is activated, causing the tripping element to disengage from the hanging ring and disconnect the line. However, in traditional tripping mechanisms, after the line is disconnected, no current flows through the current transformer, making it impossible to detect the line. Manual inspection of the line is required, and the tripping mechanism must be manually closed, resulting in a lack of convenience. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a surge protector tripping mechanism to solve the technical problem that in the prior art, after the traditional tripping mechanism trips and disconnects the line, the current transformer cannot detect the line, requiring manual detection of the line and manual reactivation of the tripping mechanism, resulting in a lack of convenience.

[0005] The purpose and effect of this surge protector tripping mechanism are achieved by the following specific technical means:

[0006] A surge protector tripping mechanism includes a housing with a mounting groove on the top. Two sets of hooks are arranged in the mounting groove, and a rotatable tripping member is arranged between the two sets of hooks. The tripping member can be connected to one of the sets of hooks. A connecting piece is provided on one side of each set of tripping members. One end of one set of connecting pieces is connected to a Hall current detection module. A second output pin is connected to one side of the Hall current detection module, and the second output pin is connected to an external detection load or a grounding wire.

Connecting buckles are provided on both sides of the release member, and connecting slots are opened on the adjacent side of the two sets of hooks corresponding to the two sets of connecting buckles.

[0008] According to a preferred embodiment, two sets of mounting plates are also provided in the mounting slot. The current transformer and the Hall current detection module are respectively mounted on the top of the two sets of mounting plates, and one end of the other set of connecting pieces is connected to the current transformer.

[0009] According to a preferred embodiment, a drive assembly is provided at the bottom of one set of mounting plates, and an isolation plate is provided between the drive assembly and the release member, with a through hole provided on the isolation plate.

[0010] According to a preferred embodiment, one end of the drive assembly is connected to an insulating connecting shaft, and the other end of the insulating connecting shaft passes through the through hole and has a connecting groove, and the bottom end of the release member is connected to the connecting groove.

[0011] According to a preferred embodiment, a top cover is provided on the top of the mounting slot, and a first connecting slot and a second connecting slot are provided on the top of the top cover. A first output pin is provided in the first connecting slot, and one side of the current transformer is connected to the first output pin.

[0014] According to a preferred embodiment, both the first output pin and the input pin are connected to an external circuit.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. By setting up a Hall current detection module, when the mechanism detects a surge and trips, the tripping component will connect to the Hall current detection module.

[0017] 2. By setting the drive component, when using this mechanism, after the Hall current detection module detects that the circuit has returned to normal, the drive component is activated to drive the tripping component to rotate through the insulated connecting shaft, so that it returns to the initial connection state and re-engages with one of the tripping components, restoring the circuit path; no manual operation by the user is required on site, which improves convenience.

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides a surge protector tripping mechanism, including a housing 11 as a support. A mounting groove 12 is formed on the top of the housing 11, and two sets of hooks 13 are arranged symmetrically within the mounting groove 12. A rotatable tripping element 14 is arranged between the two sets of hooks 13 to achieve line switching. The tripping element 14 can be connected to one of the sets of hooks 13, allowing the line current to pass smoothly. Furthermore, a connecting piece 15 is provided on one side of each set of tripping elements 14. One end of one set of connecting pieces 15 is connected to a Hall current detection module 16. The Hall current detection module 16 can be selected from A... The CS712T model can sense changes in the magnetic field in the circuit and thus obtain the current status. The Hall current detection module 16 has a second output pin 17 connected to one side. The second output pin 17 is connected to an external detection load or ground wire. In this way, when the mechanism detects a surge and trips, the tripping component 14 will disengage from one set of hooks 13 and connect to another set of hooks 13 to connect with the Hall current detection module 16. The Hall current detection module 16 continuously captures the circuit status information and detects abnormal current in the circuit, solving the problem that traditional tripping mechanisms cannot continuously detect the circuit after tripping.

[0028] Please see as follows Figure 3 and Figure 4 As shown, mounting brackets 18 are provided on the inner walls of both sides of the mounting groove 12. The mounting brackets 18 can be fixed by welding or bolt connection to ensure that there will be no loosening or displacement during the operation of the device. Hooks 13 are provided on the adjacent side of the two sets of mounting brackets 18, so that the hooks 13 are supported and can maintain a stable position during the frequent contact and disengagement of the tripping piece 14, and will not be deformed or misaligned due to external impact. Connecting buckles 19 are provided on both sides of the tripping piece 14. Connecting slots 20 are opened on the adjacent side of the two sets of hooks 13 respectively corresponding to the two sets of connecting buckles 19. When the tripping piece 14 needs to connect with the hooks 13, the connecting buckles 19 can enter the connecting slots 20 to achieve a reliable mechanical connection and ensure the stability of the line connection.

[0029] Please see as follows Figure 2 As shown, two sets of mounting plates 21 are also provided in the mounting slot 12, which can provide a stable mounting surface for the components above; the current transformer 22 and the Hall current detection module 16 are respectively installed on the top of the two sets of mounting plates 21. The current transformer 22 can be of model LZZBJ9-10C; one end of another set of connecting pieces 15 is connected to the current transformer 22. The current transformer 22 can detect whether there is a surge in the circuit based on the principle of electromagnetic induction. When a surge is detected, the rear hook piece 13 separates from one of the trip pieces 14, so that the power line is disconnected, thereby protecting other electronic equipment from the overvoltage and overcurrent impact caused by the surge.

[0030] Please see as follows Figure 2 and Figure 4 As shown, a set of mounting plates 21 has a drive assembly 23 at the bottom, which serves as the power source for rotating the tripping element 14. An isolation plate 24 is provided between the drive assembly 23 and the tripping element 14 to electrically isolate the drive assembly 23 and the tripping element 14, preventing malfunctions caused by electrical contact during the driving process and improving stability. The isolation plate 24 has a through hole, and one end of the drive assembly 23 is connected to an insulating connecting shaft 25. One end of the insulating connecting shaft 25 is connected to the drive assembly 23, and the other end passes through the through hole and has a connecting groove 26. The bottom end of the tripping element 14 is connected to the connecting groove 26. When a power surge is detected, the start-up drive assembly 23 drives the trip unit 14 to rotate via the insulated connecting shaft 25, separating it from the line with the current transformer 22 and connecting it to the line with the Hall current detection module 16. When the Hall current detection module 16 detects that the line has returned to normal, the start-up drive assembly 23 is restarted to drive the trip unit 14 to rotate, returning it to the initial connection state and restoring the line path. The entire process requires no manual operation by the user on site, improving convenience, reducing maintenance difficulty and labor costs, and enabling the power system to quickly return to normal operation after being hit by a power surge.

[0031] Please see as follows Figure 2 As shown, the top of the mounting slot 12 is provided with a top cover 27 to prevent dust, moisture and other impurities from entering and affecting the internal components; the top of the top cover 27 is provided with a first connecting slot 28 and a second connecting slot 29. The first connecting slot 28 is provided with a first output pin 30, and one side of the current transformer 22 is connected to the first output pin 30. The second connecting slot 29 is provided with a second output pin 17.

[0032] Please see as follows Figure 3 and Figure 4 As shown, a through slot is also provided at the bottom of the housing 11, and an input pin 31 is provided in the through slot. The input pin 31 serves as the entrance for external current. A connecting seat 32 is provided at the top of the input pin 31. A connecting rod 33 is provided on one side of the tripping member 14 corresponding to the connecting seat 32. One end of the connecting rod 33 is rotatably connected to the connecting seat 32. Both the first output pin 30 and the input pin 31 are connected to the external circuit, thus integrating the mechanism with the power system.
