Description

Technical Field

[0001] The invention belongs to the field of ring main units, and particularly relates to a medium and large-sized high-voltage outdoor ring main unit based on full insulation protection type. Background Technique

[0002] A ring network refers to a looped distribution network, that is, the power supply main line forms a closed loop. The power supply feeds power to this looped main line, and then distributes power outward through high-voltage switches one by one from the main line. The advantage of this is that each distribution branch can obtain power from both the left-side main line and the right-side main line. When a fault occurs in the left-side main line, it can continue to obtain power from the right-side main line, and when a fault occurs in the right-side main line, it can continue to obtain power from the left-side main line. In this way, although the total power supply is single-circuit power supply, each distribution branch can obtain the benefits similar to double-circuit power supply, thereby improving the reliability of power supply. And the "ring main unit" is to set a switch cabinet (outgoing line switch cabinet) for each distribution branch, and the busbar of this switch cabinet is simultaneously a part of the looped main line.

The other end of the clamping rod 707 is adapted to the top block 705. Limiting rings 708 are symmetrically sleeved on the outer side of the clamping rod 707.

[0033] Working principle: When in use, turn on the motor body 507 to make the output gear of the motor body 507 rotate. The output gear of the motor body 507 meshes with the upper sprocket 509, and the upper and lower sprockets 509 are driven by a chain 510. Therefore, after the output gear of the motor body 507 rotates, it drives the two rotating rings 508 to rotate. The inclination direction of the first fan blades 511 arranged on the inner wall of the upper rotating ring 508 is opposite to the inclination direction of the second fan blades 512 arranged on the inner wall of the lower rotating ring 508. Therefore, after the upper rotating ring 508 rotates, it pushes the outside cold air into the inner groove 3. After the lower rotating ring 508 rotates, it drives the hot air inside the inner groove 3 to be discharged from the inside of the inner groove 3, thereby driving the air circulation inside the inner groove 3, and thus improving the heat dissipation efficiency inside the inner groove 3;

[0034] When the upper rotating ring 508 rotates, it drives the outside cold air into the air collecting cylinder 601. Since the air collecting cylinder 601 is arranged in a frustum shape, the entering cold air is gathered. Then the cold air enters the inner groove 605, making the water-absorbing epoxy resin in the inner groove 605 contact the cold air. Thus, the water-absorbing epoxy resin absorbs the moisture in the cold air, ensuring the dryness of the air entering the inner groove 3, and thus protecting the electronic components inside the inner groove 3. A part of the cold air enters the inner groove 605 through the first air inlet hole 606, and another part of the cold air enters the inner groove 605 through the second air inlet hole 608, the outer groove 609 and the through groove 610, thereby increasing the contact area between the air and the water-absorbing epoxy resin inside the inner groove 605, and thus improving the water removal efficiency;

[0035] When the water absorption efficiency of the water-absorbing epoxy resin in the inner groove 605 decreases, the water removal cylinder 603 needs to be replaced at this time. Through the upper communication groove 501, turn the screw rod 703, so that after the screw rod 703 rotates, it moves outwards, thereby making the top block 705 move outwards. At this time, the clamping rod 707 moves back under the elastic force of the spring 710, so that the clamping rod 707 disengages from the clamping groove 701. Then take out the water removal cylinder 603, which facilitates the disassembly and assembly of the water removal cylinder 603, and thus facilitates the replacement of the water removal cylinder 603.
