Description

Technical Field

[0001] This utility model belongs to the technical field of transformer components, specifically relating to a transformer high-voltage surge arrester mounting bracket. Background Technology

[0002] Transformers are devices that use the principle of electromagnetic induction to change AC voltage. To protect transformers, surge arresters are installed, and these arresters require mounting brackets. Chinese patent CN219716649U discloses a mounting bracket for a transformer high-voltage surge arrester. The bracket assembly and rotating assembly allow the surge arrester's installation direction to be changed. Rotating the outer sleeve and rotating tube changes the connection direction of the horizontal and vertical support plates, thus altering the arrester's installation direction. However, the surge arrester is bolted to the mounting bracket's mounting seat, resulting in low assembly and disassembly efficiency and making it difficult to adjust the arrester's position on the mounting seat.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figures 1-5 The transformer high-voltage surge arrester mounting bracket shown includes: a supporting horizontal plate 1, a bearing vertical plate 4, a mounting frame plate 5, an adjustment unit 2, and a limiting unit 3.

[0028] A horizontal support plate 1 is horizontally positioned, with one end hinged to the bottom of the supporting vertical plate 4 and the other end fixed to the mounting frame plate 5. The supporting vertical plate 4 can rotate around a hinged rod located at its bottom. The mounting frame plate 5 also has mounting blocks 6 with mounting holes. The mounting blocks 6 are symmetrically arranged on opposite inner sides of the mounting frame plate 5. In this embodiment, the mounting bracket is fixedly installed on the transformer through the mounting holes in the mounting blocks 6. The transformer typically has bolt holes for installing the surge arrester mounting bracket. The mounting holes of the mounting blocks 6 are aligned with the bolt holes of the transformer, and the bracket is installed using bolts. After the mounting bracket is installed on the transformer, the surge arrester is then installed.

[0029] The adjustment unit 2 is horizontally positioned above the support plate 1. One end of the adjustment unit 2 is hinged to the top of the support plate 4, and the other end is fixed to the mounting frame plate 5.

[0030] A limiting unit 3 is installed at the upper end of the supporting vertical plate 4. The limiting unit 3 includes a supporting disc 301 and a clamping component disposed on the supporting disc 301. The supporting disc 301 is used to support the base of the surge arrester, and the clamping component is clamped to the side wall of the base of the surge arrester.

[0031] Specifically, the clamping assembly includes a bidirectional lead screw 302, a support block 303, and a limiting arc plate 304; a strip-shaped limiting groove 305 is provided at the upper end of the support disc 301; the bidirectional lead screw 302 is installed in the strip-shaped limiting groove 305 and rotates with the support disc 301; the two ends of the bidirectional lead screw 302 are provided with two threaded sections with opposite helical directions; a support block 303 is threadedly fitted on each threaded section, and the upper end of the support block 303 is connected to the limiting arc plate 304; the arc surfaces of the two limiting arc plates 304 are arranged facing each other.

[0032] After the surge arrester base is placed on the support disc 301, the two support blocks 303 are moved closer together by rotating the bidirectional lead screw 302 until the limiting arc plates 304 on the two support blocks 303 clamp onto both sides of the surge arrester base, thus clamping the surge arrester and completing the installation. The mounting bracket of this embodiment is suitable for surge arresters on transformers below 10kV. When the bidirectional lead screw 302 rotates, the support blocks 303 move along the bidirectional lead screw 302. Before installing the surge arrester, the bidirectional lead screw 302 is rotated to move the two support blocks 303 away from each other, thus reserving installation space for the surge arrester base.

[0033] To enable the limiting arc plate 304 to clamp the surge arrester, the clamping assembly also includes a locking device; the locking device is fixed within the strip-shaped limiting groove 305 and located at opposite ends of the two limiting arc plates 304. The locking device includes a tapered rubber pin; the tapered rubber pin is inserted into the strip-shaped limiting groove 305, and the sidewall of the tapered rubber pin abuts against the strip-shaped limiting groove 305 and the limiting arc plate 304.

[0034] After the limiting arc plate 304 clamps the base of the surge arrester, the conical rubber pin is inserted into the strip-shaped limiting groove 305 of the limiting arc plate 304, which is opposite to the surge arrester. The bottom diameter of the conical rubber pin is smaller than its top diameter. As the bottom of the conical rubber pin is inserted downward into the strip-shaped limiting groove 305, the side wall of the conical rubber pin abuts against the inner wall of the limiting arc plate 304 and the strip-shaped limiting groove 305 as the insertion depth increases. The conical rubber pin is locked, restricting the displacement of the limiting arc plate 304, thus clamping the surge arrester with the two limiting arc plates 304. When it is necessary to remove the surge arrester, pull out the conical rubber pin and push the two limiting arc plates 304 away from each other, thereby releasing the clamp on the surge arrester and allowing it to be removed.

[0035] In some embodiments, the locking device may also be other structures, such as a wedge block that is inserted into the strip-shaped limiting groove 305 and abuts against the limiting arc plate 304.

[0036] like Figure 3 As shown, the adjustment unit 2 includes a sliding assembly, an adjustment crossbar 207, a first hinge rod 205, and a second hinge rod 206. The first hinge rod 205 and the second hinge rod 206 are connected to both ends of the adjustment crossbar 207, respectively. The first hinge rod 205 is hinged to the sliding assembly, which is connected to the mounting frame 5, and is used to drive the first hinge rod 205 closer to or further away from the mounting frame 5. The second hinge rod 206 is hinged to the supporting vertical plate 4. The sliding assembly includes a strip box 201, a transverse lead screw 202, a guide block 203, and a pusher frame 204. The strip box 201 is connected to the mounting frame 5, and its interior is provided with a cooperating transverse lead screw 202 and a guide block 203. One side of the strip box 201 has an opening slot for the guide block 203 to partially extend. The guide block 203 extending from the opening slot is connected to the pusher frame 204. The first hinge rod 205 is mounted on the pusher frame 204. One end of the transverse lead screw 202 extends out of the strip box 201 and is connected to a knob for driving the transverse lead screw 202 to rotate. The sliding assembly also includes a transverse guide rod 208; the transverse guide rod 208 is parallel to the transverse lead screw 202. There are two strip boxes 201, and the transverse guide rod 208 and the transverse lead screw 202 are respectively disposed in the two strip boxes 201. The push frame 204 is located between the two strip boxes 201. One end of the push frame 204 is connected to the transverse lead screw 202 through a guide block 203, and the other end of the push frame 204 is connected to the transverse guide rod 208 through another guide block 203.

[0037] When the transverse lead screw 202 rotates, the guide block 203 that cooperates with it moves along the length of the transverse lead screw 202, moving closer to or away from the mounting frame plate 5. The push frame 204 connected to the guide block 203 moves synchronously, thereby driving the adjusting crossbar 207 to move synchronously, causing the bearing vertical plate 4 connected to the adjusting crossbar 207 to move synchronously, moving closer to or away from the mounting frame plate 5. The guide block 203 connected to the other end of the push frame 204 is fitted onto the transverse guide rod 208. The guide block 203 slides on the transverse guide rod 208, and under the action of the transverse guide rod 208 and the guide block 203 thereon, the push frame 204 slides smoothly.

[0038] When the horizontal bar 207 is moved away from the mounting frame plate 5, the bearing vertical plate 4 tilts towards the side away from the mounting frame plate 5. When the horizontal bar 207 is moved closer to the mounting frame plate 5, the bearing vertical plate 4 tilts towards the side closer to the mounting frame plate 5.

[0039] In some embodiments, the adjusting unit 2 further includes a locking member for restricting the movement of the guide block 203, thereby limiting the support vertical plate 4 to a specific tilt angle. The locking member may be a rubber stopper inserted into the opening slot of the strip box 201. The rubber stopper is inserted into the strip box 201 and located on both sides of the guide block 203, abutting against the guide block 203, thereby restricting the movement of the guide block 203.

[0040] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
