〔発明の目的〕
(産業上の利用分野)
本発明は液体からなる冷却媒体により発熱部を冷却する
構造を有する高電圧電気機器に関する。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a high-voltage electric device having a structure in which a heat generating part is cooled by a cooling medium made of a liquid.
(従来の技術)
一般に、サイリスタバルブ装置、ガス絶縁変圧器等の高
電圧電気機器においては、絶縁ガスの冷却能力を補うた

却性に優れた有機化合物により発熱部を冷却する構造が
採用されている。(Prior technology) In general, in high-voltage electrical equipment such as thyristor valve devices and gas-insulated transformers, in order to supplement the cooling ability of insulating gas, organic liquids with excellent insulating and cooling properties such as perfluorocarbon liquid and fluorocarbon liquid are used. A structure is adopted in which the heat generating part is cooled by a compound.
また、通常発熱部は高電圧側にあり、熱交換器は接地電
位側に配設される。Further, the heat generating part is usually located on the high voltage side, and the heat exchanger is usually arranged on the ground potential side.
従って、冷却媒体の循環系は高電圧絶縁を保持する必要
があり、冷却媒体を通すパイプは高分子樹脂等の絶縁物
を利用して絶縁を保持している。Therefore, the cooling medium circulation system must maintain high voltage insulation, and the pipes through which the cooling medium passes are kept insulated by using an insulating material such as polymer resin.
ここで、サイリスタバルブ装置を例にとり従来の高電圧
電気機器の構成を第9図及び第10図を用いて説明する

3間を循環し再び他方の集液管7に戻る。Here, the configuration of a conventional high-voltage electric device will be explained using FIGS. 9 and 10, taking a thyristor valve device as an example. A thyristor stack 3 consisting of a large number of thyristor elements and a shield electrode 4 are insulated and supported by insulating spacers 5 and housed in a gas container 1 filled with an insulating gas 2 such as SF or gas. The perfluorocarbon liquid, which is a cooling medium, is circulated between the thyristor stacks 3 from one liquid collecting pipe 7 at ground potential by an insulating vibro made of polymer resin, and returns to the other liquid collecting pipe 7 again.

続されている。Furthermore, a piping 8 made of a metal pipe connected to a pair of liquid collecting pipes 7 is disposed outside the gas container 1 . A pump 9, a heat exchanger IO, and a pressure regulator 11 that prevents pressure from being applied to the insulated pipe are connected in the middle of the pipe 8.
ところで、パーフロロカーボン液が矢印12で示す流れ
を生じると、流動帯電により、冷却媒体であるパーフロ
ロカーボン液は負に帯電し、金属に正電荷を与える。そ
して、負に帯電した冷却媒体が絶縁バイブロ内を流動す
ると、絶縁バイブロは負に帯電し高電位になる。By the way, when the perfluorocarbon liquid generates the flow shown by the arrow 12, the perfluorocarbon liquid, which is a cooling medium, becomes negatively charged due to flow charging, and gives a positive charge to the metal. When the negatively charged cooling medium flows through the insulating vibro, the insulating vibro becomes negatively charged and has a high potential.
このような流動帯電は、配管据付時に混入する塵埃や配
管のM等の導電性粒子により大きく加速され、導電性粒
子の大きさが大きい程顕著となることが知られている。It is known that such flow charging is greatly accelerated by conductive particles such as dust mixed in during piping installation and conductive particles such as M in the piping, and becomes more pronounced as the size of the conductive particles increases.
また、流動帯電は、絶縁バイブロの沿面及び貫通方向に
放電を発生させ、絶縁バイブロの破損や絶縁ガス2の絶
縁破壊を誘発する危険性がある。In addition, the flowing electrification causes discharge to occur along the creeping surface and in the penetrating direction of the insulating vibro, and there is a risk of inducing damage to the insulating vibro and dielectric breakdown of the insulating gas 2.
そこで、配管8の途中にメツシュ状構造物13を垂直に
設け、一定以上の大きさの導電性粒子をメソシュ状構造
物13で捕獲する方法が採用されている。Therefore, a method is adopted in which a mesh-like structure 13 is provided vertically in the middle of the pipe 8 and conductive particles of a certain size or more are captured by the mesh-like structure 13.
しかしながら、この方法ではメツシュ状構造物13が目
詰りを起し易く、冷却媒体の流速が低下し冷却効率が低
下するとともにポンプ9に大きな負荷がかかることにな
る。However, in this method, the mesh-like structure 13 is likely to become clogged, the flow rate of the cooling medium is reduced, the cooling efficiency is reduced, and a large load is placed on the pump 9.

が低下する。(Problems to be Solved by the Invention) As described above, in conventional high-voltage electrical equipment, conductive particles that generate flowing electrification are captured by a mesh-like structure provided in the piping. As a result, the mesh-like structure is clogged with conductive particles, causing damage to the insulating pipe and dielectric breakdown of the insulating gas. Moreover, the cooling efficiency of the heat generating part is reduced, and the life characteristics and reliability of the high voltage electrical equipment are reduced.
