いる。2. Description of the Related Art In this type of conventional switchgear, the insulator type circuit breaker shown in FIG. 6 is typical. In FIG. 6, the breaking device 1 is configured by installing a fixed electrode 3 and a movable electrode 4 in a porcelain porcelain tube 2 filled with an insulating gas, for example, SF6 gas. A nozzle 5 is fixed to the movable electrode 4. In FIG. 6, a porcelain porcelain tube 2 composed of these electrodes 3 and 4 and a nozzle 5 is provided near the contact point.

【発明が解決しようとする課題】上述した従来の碍子形
遮断器においては、固定電極３および可動電極４により
構成される開閉装置接点が、磁器碍管内部に設置されて
いることから、その開閉状態を直接目視することができ
ない、という欠点がある。In the above-mentioned conventional insulator-type circuit breaker, since the switch contact formed by the fixed electrode 3 and the movable electrode 4 is installed inside the porcelain porcelain tube, its open / closed state. Has the drawback that it cannot be directly observed.
【０００５】このことは、機器の保守点検のために作業
員が高電圧導体に直接触れるときに、特に重要な課題と
なる。すなわち、開閉装置の接点の開閉状態が直接作業
員の目で確認できる状態であれば、その状態を見誤るこ
とはなく、確実に、また安心して作業を遂行できる。This is a particularly important problem when a worker directly touches the high voltage conductor for maintenance and inspection of equipment. That is, if the open / closed state of the contacts of the switchgear can be directly confirmed by the operator's eyes, the state is not mistaken, and the work can be performed reliably and with peace of mind.

リンクが外れていて、ON,OFF表示が実際の接点の開閉状

性が存在する。However, if the open / closed state cannot be directly visually confirmed, and there is no choice but to rely on the ON / OFF display of the contact through the operation mechanism of the contact, that is, via the link, the link is disconnected, and If the ON / OFF display differs from the actual open / close state of the contact, there is a possibility of causing a serious human injury.

器であるからである。This situation is more prominent in an insulator-type disconnector, in which the disconnector contact, which has recently started to be noticed, is installed in the insulator tube, as compared with the conventional insulator-type circuit breaker. That is, when a worker directly touches the high-voltage conductor, it is the disconnector that normally disconnects the high-voltage charging unit.

は、作業員は遮断器であっても高圧充電部に触れる場合
がある。However, in recent years, for the purpose of reducing the cost of substation construction, there is a movement to make the circuit breaker function as a disconnector to reduce the number of disconnectors. In such a situation, the worker may touch the high-voltage charging section even with the circuit breaker.
