封入された容器内に一括して収納してなるガス絶
縁開閉装置に関する。[Detailed description of the invention] This invention is a gas insulation system in which the beam, disconnector, disconnector, earthing switch, bus bar, and other components are all housed in a container filled with an insulating medium such as SF 6 gas. Regarding switchgear.

ころである。 This type of gas-insulated switchgear is different from conventional systems in which individual components are housed in cylindrical or spherical metal capsules and electrically connected to each other.
By significantly improving the space utilization rate as a box, it is possible to downsize the entire device and improve economic efficiency, as well as reduce the number of gas-tight areas, the number of parts, and gas piping. Because of the advantages associated with this, such as improved reliability of the device and improved environmental friendliness, its adoption is being widely considered.

がある。 In this type of device, as shown in FIG.
SF 6 gas at a relatively high pressure is sealed in order to satisfy the current insulation performance, and in order to reduce the manufacturing cost of the box 1, the box body 1 has a length that satisfies the insulation performance. It is filled with low pressure (usually slightly above atmospheric pressure) SF 6 gas. Since the shield breaker 2 disconnects a large current in the event of a short-circuit accident, it is necessary to maintain and replace the contacts at necessary intervals.

ケース３の開口を覆うマンホール蓋である。 An insulated operating rod connected to a movable earpiece is housed within the shield disconnector 2, and this insulated operating rod is connected to a crank lever housed within the crankcase 3. However, in the case of the conventional device, the relationship between the insulating tube 5 of the sheath breaker 2 and the crankcase 3 is as shown in FIG. are both fixed by bolts 6 and 7. Note that 8 and 9 are gaskets that prevent the gas in the insulating cylinder 5 from leaking into the box 1 or outside, and 10 is a manhole cover that covers the opening of the crankcase 3.
このように従来装置では、側壁４に絶縁筒５と
クランクケース３をそれぞれ支持固定しているの
で以下のような欠点を有する。即ち、
１ しや断器を完成状態で箱体に装着できないた
め、箱体内のせまいスペースでしや断器を組立
てる必要があり組立の作業性が良くない。 As described above, the conventional device has the following drawbacks because the insulating tube 5 and the crankcase 3 are supported and fixed to the side wall 4, respectively. That is, 1. Since the cylindrical breaker cannot be attached to the box body in a completed state, it is necessary to assemble the cylindrical breaker in a small space inside the box body, resulting in poor assembly work efficiency.
２ 箱体に組込み完了するまでしや断器が完成し
ないので、しや断器単体試験ができず箱体組立
完成後しや断器の試験をする必要があり装置の
検査スケジユールが長くなる。2. Since the shield breaker is not completed until it is assembled into the box, it is not possible to test the shield breaker individually, and it is necessary to test the shield breaker after the box is assembled, which lengthens the equipment inspection schedule.
３ 側壁の内面に気密パツキンを装着するための
加工を要しコストが高くつくばかりか、絶縁筒
のガス洩れチエツクの作業性が悪い。3. Processing is required to attach the airtight packing to the inner surface of the side wall, which not only increases the cost, but also makes it difficult to check for gas leaks from the insulating cylinder.
この考案は上記従来装置の欠点を解消すること
を目的とする。 The purpose of this invention is to eliminate the drawbacks of the above-mentioned conventional devices.
以下この考案の一実施例を第３図について説明

相当部分を示す。 An embodiment of this invention will be described below with reference to FIG. Note that the same reference numerals as in FIGS. 1 and 2 indicate the same or corresponding parts.

れた凹部に装着されている。 As can be easily understood from FIG. 3, in this invention, the insulating cylinder of the breaker and the crankcase 3 are fastened together with bolts 6, and the crankcase 3 is supported on the side wall 4 of the box body 1 by bolts 7. Fixed. Note that 9 and 10 are gas leakage prevention gaskets, which are mounted in recesses provided in the crankcase 3.
以上のようにこの考案の構成によれば、しや断

果が著しい。 As described above, according to the configuration of this invention, it is possible to attach the capacitor to the box body in a fully assembled state, so there is no need to assemble the capacitor to the box body, and the assembly work efficiency is greatly improved. improve. Since the shield disconnector itself can be attached to the box body after completing the necessary operation tests and airtightness tests, the number of days required for equipment inspection etc. can be shortened and the mass production effect is large. Unlike the conventional method, there is no need for machining to attach an airtight gasket to the inner surface of the side wall, so there are significant effects such as a significant reduction in machining costs.
