[0002] The voltage regulating switch of the existing wind power box transformer is mostly operated by manual rotation, which is simple in structure and low in cost.

[0022] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0023] The embodiments described in some embodiments of the present disclosure below do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.
[0024] like Figures 1 to 3 As shown, the present disclosure exemplarily provides a box-type on-load voltage regulating gear position anti-misoperation device, including a gear switch 1 and a base 2, wherein the gear switch 1 is provided with a first rotation limit structure 11, and the base is provided with a second rotation limit structure 21, the first rotation limit structure 11 and the second rotation limit structure 21 can cooperate to limit the circumferential rotation of the gear switch 1, and the gear switch 1 can be lifted relative to the base 2 to separate the first rotation limit structure 11 and the second rotation limit structure 21, and the box-type on-load voltage regulating gear position anti-misoperation device also includes a locking structure 3, which is used to lock the gear switch 1 in the rotation limit position.
[0025] The operator can perform the voltage adjustment operation by rotating the gear switch 1. The rotation limit structure can limit the circumferential rotation of the gear switch 1. Specifically, the circumferential rotation of the gear switch 1 is limited so that the gear switch 1 cannot perform the voltage adjustment operation, thereby achieving the purpose of preventing misoperation. The rotation limit structure can only limit the circumferential rotation of the gear switch 1, but not the movement of the gear switch 1 along the lifting direction. By lifting the gear switch 1, the first rotation limit structure 11 and the second rotation limit structure 21 can be separated. Once the two are separated, they no longer have the function of limiting the circumferential rotation of the gear switch 1, and the operator can perform the voltage adjustment operation. Conversely, for example, when the voltage adjustment operation is completed, the gear switch 1 is pressed down so that the first rotation limit structure 11 and the second rotation limit structure 21 are in the limit matching state again, which can prevent outsiders from misoperating the gear switch 1.
[0026] Considering that the rotation limit structure only limits the circumferential rotation of the gear switch 1, but does not limit the lifting direction of the gear switch 1, once an outsider mistakenly lifts the gear switch 1 and causes the first rotation limit structure 11 and the second rotation limit structure 21 to separate, there is still a risk of misoperation. Based on this, the on-load voltage regulation gear misoperation prevention device provided by the present disclosure also includes a locking structure 3, which is used to lock the gear switch 1 in the rotation limit position along the lifting direction. In this way, even if an outsider has the action of lifting the gear switch 1 upward, due to the existence of the locking structure 3, it is impossible to finally lift the gear switch 1 and separate the first rotation limit structure 11 and the second rotation limit structure 21, thereby achieving the purpose of preventing misoperation.
[0027] The technical solution provided by the embodiments of the present disclosure may include the following beneficial effects: the on-load voltage regulating gear position anti-misoperation device for the box-type transformer provided by the present disclosure sets a first rotation limit structure 11 on the gear switch 1 and sets a second rotation limit structure 21 on the base 2, so that when the gear switch is not lifted to separate the first rotation limit structure 11 and the second rotation limit structure 21, the gear switch 1 is in a state where it cannot rotate. At the same time, the on-load voltage regulating gear position anti-misoperation device for the box-type transformer is also provided with a locking structure 3 that can lock the gear switch 1 in a rotation limit position, so that the gear switch 1 cannot be lifted when locked, and thus cannot rotate, thereby achieving the purpose of preventing misoperation. The dual anti-misoperation structure formed by the rotation limit structure and the locking structure 3 of the present disclosure is conducive to improving the reliability of the anti-misoperation device and ensuring the safe and stable operation of the equipment.
[0028] like Figure 2 As shown, the first rotation limiting structure 11 can be configured as a limiting block 111, and the second rotation limiting structure 21 can be configured as a limiting groove 211 that can cooperate with the limiting block 111, and the limiting groove 211 can limit the circumferential rotation of the limiting block 111. Specifically, the base 2 is configured to be fixed relative to the box of the transformer, so that when the limiting block 111 is inserted into the limiting groove 211, the position of the limiting block 111 remains fixed in the circumferential direction, and then the gear switch 1 also remains fixed in the circumferential direction.
[0029] Also refer to Figure 2 and Figure 3, the limit blocks 111 and the limit grooves 211 are respectively provided with a plurality of matching numbers, and the plurality of limit blocks 111 and the limit grooves 211 are arranged at intervals along the circumferential rotation direction. Among them, the number of limit blocks 111 and the limit grooves 211 can be determined according to the number of gears that need to be adjusted, that is, a limit groove 211 and a limit block 111 can be set according to the angle that the gear switch 1 needs to rotate for each gear adjustment, so that in each pressure adjustment gear, it can be ensured that the first rotation limit structure 11 and the second rotation limit structure 21 cooperate after the gear switch 1 is pressed down.
[0030] It should be noted that the present disclosure is not intended to limit the specific form of the locking structure 3, and any structure and method that can achieve locking the gear switch 1 in the rotation limit position along the lifting direction can be applied to the present disclosure. Figure 1 As shown, the locking structure 3 includes a hook 31 and a padlock 32. The hook 31 is arranged on the outer edge of the base 2, and the padlock 32 is passed between the hook 31 and the gear switch 1. The outer edge of the gear switch 1 is formed with a retaining edge 12 that can be stopped by the padlock 32 in the lifting direction. The combined structure of the hook 31 and the padlock 32 is simple and easy to operate. The hook 31 is arranged on the outer edge of the base 2 and forms a space for the padlock 32 to pass through with the base 2.
[0031] During operation, the gear switch 1 is first pressed down to make the first rotation limit structure 11 and the second rotation limit structure 21 cooperate, and then the padlock 32 is inserted between the hook 31 and the gear switch 1. In this way, when an outsider lifts the gear switch 1 outward, the padlock 32 forms a stop for the retaining edge 12 of the hook 31, preventing the gear switch 1 from being further lifted to the position where the first rotation limit structure 11 and the second rotation limit structure 21 are separated.
[0032] Furthermore, a circular arc-shaped receiving groove 311 is provided on one side of the hook 31 facing the inside of the base 2, and the portion of the padlock 32 that passes between the hook 31 and the gear switch 1 is received in the receiving groove 311 in a matching shape. The receiving groove 311 has a limiting effect on the padlock 32, that is, it prevents the padlock 32 from being moved unexpectedly by the retaining edge 12, thereby affecting the locking effect of the gear switch 1.
[0033] In some other embodiments, in addition to the locking structure 3 of the hook 31 and the padlock 32 mentioned above, the locking structure 3 can also adopt a snap-on connection method, or a pin that can penetrate the gear switch 1 and the base 2 at the same time, etc., which will not be repeated here.
[0034] like Figure 2As shown, the gear switch 1 can be configured to include an operating handle 13 and an operating rod 14 for cooperating with the base 2, and the first rotation limiting structure 11 is arranged on the operating rod 14. The operating handle 13 can be constructed into a spherical or spherical shape suitable for holding. Optionally, an anti-slip structure can be provided on the operating handle 13, such as an anti-slip protrusion or a layer of anti-slip rubber pad. The operating handle 13 and the operating rod 14 can be constructed as an integrated structure, that is, the operating handle 13 and the operating rod 14 are integrally formed, with a simple structure and low cost. Of course, the operating handle 13 can also be a split structure with the operating rod 14. For example, different operating rods 14 can be provided with second rotation limiting structures 21 adapted to different bases 2, such as second rotation limiting structures 21 with different shapes or different numbers of second rotation limiting structures 21, thereby improving the versatility of the gear switch 1.
[0035] In addition, in order to further prevent outsiders from misoperating the gear switch 1, the on-load voltage regulation gear misoperation device provided by the present disclosure may further include a transparent protective cover arranged outside the gear switch 1, which can prevent misoperation and allow the gear switch 1 to be seen. In addition, a warning sign for warning outsiders not to tamper with the gear switch 1 may be arranged on the transparent protective cover.
[0036] According to the second aspect of the embodiment of the present disclosure, there is also provided a box-type transformer, comprising any one of the above-mentioned box-type transformer on-load voltage regulation gear misoperation devices, and having all its beneficial effects, which will not be repeated here.
[0037] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.
[0038] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.
[0039] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
