Description

Technical Field

[0001] The present invention relates to the technical field of power equipment, and more particularly to an insulating support structure of high-stability power transformation equipment. Background Art

[0002] The high-voltage busbar bridge in a substation, also known as a bridge connection, is the main connection that connects two power supply lines to two transformers using a jumper circuit breaker (BCD). During installation, especially when erected outdoors, the busbar bridge requires support and fixation.

[0003] For example, application number 2023213444109 discloses a substation high-voltage busbar bridge support device, which relates to the technical field of substation auxiliary equipment, specifically a substation high-voltage busbar bridge support device, including a support plate and an adjustment frame, the upper surface of the support plate is provided with an insulating column, the insulating column is provided with a connecting plate at one end away from the support plate, the interior of the connecting plate is provided with a mounting groove, the interior of the mounting groove is rotatably connected to a connecting shaft, the outer surface of the connecting shaft is provided with an adjusting gear, the adjusting gear is located inside the mounting groove, and a limiting ratchet is provided at the end of the connecting shaft away from the adjusting gear.

[0004] In the supporting structure, the insulating column is used to achieve the insulation function. Since the outer side of the insulating column is provided with a vertically arranged skirt structure, dust is easily accumulated inside, so it needs to be cleaned regularly. In addition, once the insulating column is cracked or damaged, it must be replaced to ensure its normal insulation performance, thereby ensuring the stable power supply of the cable. However, the current insulating columns are usually connected by independent vertical bolts, which makes the connection easy to loosen and lack stability. At the same time, during the replacement operation, since the power supply needs to be kept on, the connection between the cable and the insulating column must be manually disassembled, which not only increases the operational risk, but also makes the disassembly and replacement process quite difficult.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention; See also Figures 1 to 6 In the present invention, an insulating support structure of a high-stability substation equipment includes a base 1, a telescopic rod 2 is installed on the top of the base 1, a lifting plate 4 is fixedly installed between the top ends of the two telescopic rods 2, two positioning blocks 5 are installed on the top of the base 1, an adjusting member 6 is installed between the two positioning blocks 5, the top of the adjusting member 6 is in contact with the lifting plate 4, and three equidistantly arranged circular grooves 7 are opened on the top of the lifting plate 4. Four studs 8 are fixedly installed inside the circular grooves 7, and insulators 9 are fixedly installed between the four studs 8 by bolts. A first connecting plate 10 is fixedly installed on the top of the insulator 9, and the first connecting plate 10 is fixedly connected to a wire clamping assembly 11 by bolts.

[0019] The wire clamping assembly 11 includes a connecting seat 111, an upper clamp 112, a clamping mechanism 113 and a positioning member 114. The connecting seat 111 is fixedly connected to the insulator 9 by bolts. The bottom of one side of the upper clamp 112 is hinged to the connecting seat 111. The clamping mechanism 113 is installed on the upper clamp 112. The positioning member 114 is installed on the connecting seat 111 and is movably connected and cooperated with the upper clamp 112.

[0020] In the present invention, the base 1 is used as the device support installation, and the base 1 is used to be installed on the substation equipment, and then the high-voltage cable is passed through the wire clamping assembly 11 to achieve support for the high-voltage cable. The adjustment member 6 between the two positioning blocks 5 is used for adjustment to drive the lifting plate 4 to move vertically. At the same time, the two telescopic rods 2 cooperate with the adjustment member 6 to stably support the lifting plate 4 and adjust the support height of the insulator 9 at the same time. The operation is flexible and the support stability is good.

[0021] When the insulator 9 needs to be replaced and cleaned, first remove the bolt connection between the first connecting plate 10 on the top of the insulator 9 and the connecting seat 111. At this time, the entire wire clamping assembly 11 remains connected to the cable, and the insulator is removed independently. Then, the stud 8 inside the bottom circular groove 7 is used to remove the insulation 9 from the base 1 lifting plate 4. At this time, modular disassembly and assembly between the insulator 9, the wire clamping assembly 11 and the lifting plate 4 are realized. At this time, the disassembled insulator 9 is cleaned and replaced, and the operation is more convenient and efficient.

[0022] During installation, the cable is placed inside the connecting seat 111, and then the upper clamp 112 is closed, and the upper clamp 112 is positioned using the positioning piece 114, and then the clamping mechanism 113 is tightened to clamp and position the cable, thereby realizing that the device has the advantages of modular independent disassembly and assembly of the insulating column, high efficiency and flexibility, convenient cleaning of the interior, and efficient replacement of damaged insulating columns, and safer operation. It solves the problem in the prior art that once cracking and damage occur, replacement is required to ensure normal insulation of the insulating column and normal power supply of the cable. However, the current insulating columns are generally connected with independent vertical bolts, which are easy to loosen and have poor stability. At the same time, during the replacement operation, since the existing operation requires non-stop power supply, the connection between the cable and the insulating column needs to be manually removed, and the operation risk is very high, and disassembly and replacement are difficult.

[0023] See also Figure 3 and Figure 5 , wherein: the clamping mechanism 113 includes an I-frame 1131, an adjusting rod 1132 and a sliding block 1133, the I-frame 1131 is fixedly mounted on the upper clamp 112, the bottom end of the adjusting rod 1132 passes through and is threadedly connected to the bottom of the I-frame 1131, the bottom end of the adjusting rod 1132 is rotatably connected to the sliding block 1133, and the outer side of the sliding block 1133 is slidably connected to the upper clamp 112.

[0025] See also Figure 3 and Figure 5 , wherein: the positioning member 114 includes a C-shaped rod 1141 and a tension spring 1142, the bottom end of the C-shaped rod 1141 passes through and is slidably connected to the interior of the connecting seat 111 and is elastically connected to the connecting seat 111 through the tension spring 1142, and the top end of the C-shaped rod 1141 passes horizontally through and slides into the interior of the upper clip 112.

[0026] In the present invention, the C-shaped clamping rod 1141 is cooperated with the tension spring 1142 to pull the C-shaped clamping rod 1141 to stretch the tension spring 1142, so that the top end of the C-shaped clamping rod 1141 is separated from the upper clamp 112 to release the separation of the upper clamp 112. Conversely, under the pulling force of the tension spring 1142, the C-shaped clamping rod 1141 clamps and positions the upper clamp 112, and the loading and unloading operations are more stable.

[0027] See also Figure 1, wherein: the adjusting member 6 includes a toggle block 61, a horizontal screw 62 and two supporting sliders 63, the inner part of the toggle block 61 is fixedly connected to the outer side of the horizontal screw 62, the two ends of the horizontal screw 62 respectively pass through and are threadedly connected to the two sides of the two supporting sliders 63, and the two ends of the two horizontal screws 62 are respectively rotatably connected to the two positioning blocks 5.

[0028] In the present invention, the horizontal screw 62 is driven to rotate by the toggle block 61 to drive the two supporting sliders 63 to move relative to each other along the horizontal screw 62, so as to realize the lifting and lowering adjustment of the lifting plate 4, which is convenient to operate and has a more stable supporting effect.

[0030] In the present invention, by rotating the adjusting disk 91 to move vertically along the outer side of the insulator 9, the elastic sleeve 92 and the rubber ring 93 at the bottom are driven to descend and contact the lifting plate 4, thereby waterproofing and sealing the circular groove 7 to achieve anti-corrosion protection.

[0032] In the present invention, the first arc groove 1134 cooperates with the second arc groove 115 to form a cable placement cavity, and the flexible insulating pad 3 is used to effectively improve the insulation effect of the entire device.

[0033] See also Figure 2 and Figure 4 , wherein: a plum blossom disk 12 is fixedly installed at the bottom of the insulator 9, and a connecting hole 13 for the stud 8 is opened on the plum blossom disk 12.
