Description

【考案の詳細な説明】〔産業上の利用分野〕本考案は、開閉器内に浸入した水分や消弧ガス
が分解してできた有害ガスを吸着するための吸着
剤を収納する装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device that houses an adsorbent for adsorbing harmful gases produced by decomposing moisture and arc-extinguishing gas that have entered a switch.

[Conventional technology]

ガス開閉器は、接触子の開放時のアークを消弧
したり、絶縁特性を維持するためにケース内部に
SF₆ガス等のガスを封入したものである。 A gas switch is installed inside the case to extinguish the arc when the contact opens and to maintain insulation properties.
It is filled with gas such as SF ₆ gas.

このケース内に水分が浸入すると、絶縁特性が
低下し、また開閉時のアーク熱によりSF₆ガスの
分解ガスが発生し、また水素と化合してHFガス
になるなど、有害な活性ガスが生成し、これがケ
ースや接触子を腐食させるなど種々の悪影響を及
ぼす。 If moisture enters the case, the insulation properties will deteriorate, and the arc heat during opening and closing will generate decomposition gas of SF ₆ gas, which will also combine with hydrogen to become HF gas, producing harmful active gases. However, this has various adverse effects such as corrosion of the case and contacts.

これを防止するために、合成ゼオライト等の吸
着剤を開閉器のケース内に収納し、水分や活性ガ
スを吸着するようにしている。 To prevent this, an adsorbent such as synthetic zeolite is housed in the case of the switch to adsorb moisture and active gas.

従来、この吸着剤を収納するための構造とし
て、例えば第５図に示すように、ケース３１の天
井部に収納部３２を設けていた。図中３３は固定
接触子、３４は可動接触子、３５は操作レバーで
ある。 Conventionally, as a structure for storing this adsorbent, for example, as shown in FIG. 5, a storage section 32 has been provided in the ceiling of a case 31. In the figure, 33 is a fixed contact, 34 is a movable contact, and 35 is an operating lever.

[Problem that the invention attempts to solve]

しかしながら、このような構造であると、接触
子３３，３４などの充電部からの絶縁距離等の関
係で、ケース３１のサイズを、通常の天井高さ
H₀から、収納部３２を設けた分だけH₁の高さに
高くしなければならず、ケースの大型化、コスト
アツプにつながるという問題があつた。 However, with such a structure, the size of the case 31 is limited to the normal ceiling height due to insulation distance from live parts such as the contacts 33 and 34.
The height must be increased from H ₀ to H ₁ by the amount that the storage section 32 is provided, which poses the problem of increasing the size of the case and increasing costs.

本考案は、このような、吸着剤収納スペースに
よりケースの形状が大型化するという問題点を解
決することを目的とするものである。 The present invention aims to solve the problem of increasing the size of the case due to the adsorbent storage space.

[Means for solving problems]

器のガス吸着剤収納装置である。 The present invention provides a switch in which a pressure relief plate is provided in the center of a side plate of a switch case, which bulges out in a dome shape toward the inside of the case, and the side plate has an opening at a location facing the pressure relief plate. A gas adsorbent storage device for a switch is further characterized in that a partition plate is attached between the gas adsorbent storage device and the side plate to form an adsorbent storage interval approximately equal to the bulging height of the pressure relief plate.

これによつて、従来、活用されていないデツド
スペースに吸着剤を収納することができ、開閉器
ケース自体の大きさを変える必要がなくなる。 As a result, the adsorbent can be stored in a dead space that has not been utilized conventionally, and there is no need to change the size of the switch case itself.
