【発明の詳細な説明】
本発明はガスしや断器に係り、特にガスしや断
器の試験方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to gas cylinders and disconnectors, and particularly to a method for testing gas cylinders and disconnectors.
従来、SF6ガスしや断器においては、投入及び

整を行なつていた。 Conventionally, when performing operation tests to check the on-off and on-off times or the operating characteristics of resistance devices, etc., SF 6 gas insulators and disconnectors have been filled with a single charge gas to maintain the same operating conditions. Then, the operating characteristics were measured, and if the results showed that the characteristics deviated from the specified values, the gas was vented and the resistance device etc. were readjusted.
しかし、SF6ガスは、空気等の他のガスが混入
した場合、絶縁性能が低下するので、ガス容器の
真空引等を十分を行なう必要があり、ガス排気、
ガス充填などに時間がかかるばかりでなく、高価
なSF6を放散してしまうという欠点があつた。 However, when SF 6 gas is mixed with other gases such as air, its insulation performance deteriorates, so it is necessary to thoroughly vacuum the gas container,
Not only did it take time to fill the gas, but it also had the disadvantage of emitting expensive SF 6 .
本発明の目的は、ガスの排気及び充填時間を短
縮し試験時間を短縮した試験方法を提供するにあ
る。 An object of the present invention is to provide a test method that shortens the gas evacuation and filling time, thereby shortening the test time.
本発明は、SF6ガスしや断器の操作試験を行な

操作を行なうものである。 In the present invention, when performing an operation test of an SF 6 gas tank or disconnection switch, the SF 6
Instead of gas, other inexpensive and easily managed gases are sealed and operated.
以下、本発明を図面に示す実施例により説明す
る。 The present invention will be explained below with reference to embodiments shown in the drawings.

施し時間の協調を確認する。本操作試験方法は、
ガス容器内に、しや断部を構成し運転状態と同じ
状態に、SF6ガスを充填する前に次のような異種
ガスを充填し操作試験を行なうものである。 The drawing is a schematic diagram showing the contact configuration of a general gas shield and disconnector. In the figure, contacts 1 and 2 are arranged in parallel with closing resistance contacts 3 and 4 to constitute an opening/closing section 6, which is housed in a gas container 5. For gas cylinders and disconnectors, the opening and closing times of the main contact and closing resistance contact described above are required to be within a certain range, so an operation test of the opening/closing part 6 is carried out after assembly.
Check the coordination of almsgiving times. This operation test method is
The gas container is constructed with a shear section, and before being filled with SF 6 gas, an operation test is performed by filling the container with the following different gases in the same state as the operating condition.
例えば、SF6に比べて安価で管理の容易な空
気、ちつそ窒素フレオンガス等を充填しておこな
う。 For example, fill with air, nitrogen, freon gas, etc., which is cheaper and easier to manage than SF 6 .
操作試験を完了した後は、これらのガスを上記
ガス容器から回収又は大気中に放出し、真空引を
行ない運転状態のSF6ガスを例えば５気圧充填す
る。 After the operation test is completed, these gases are collected from the gas container or released into the atmosphere, and the container is evacuated and filled with SF 6 gas of, for example, 5 atmospheres in the operating state.
この場合、運転状態つまりSF6ガスを５気圧充
填した場合と他のガスを充填した場合の操作特性
をあらかじめ把握しておくことにより、操作特性
の適否を容易に判定できる。 In this case, by knowing in advance the operating conditions, that is, the operating characteristics when filling with 5 atmospheres of SF 6 gas and when filling with other gases, it is possible to easily determine whether the operating characteristics are appropriate.
この断定を容易にするには、空気、窒素ガス、
フレオンガス等のガスを単種で用い、圧力を管理
すれば良い。これらのガスについては、他種のガ
スの多少の混入があつても特性が変化せず、充填
及び回収の時間が非常に短かい。 To facilitate this assertion, air, nitrogen gas,
It is sufficient to use a single type of gas such as Freon gas and control the pressure. The characteristics of these gases do not change even if a certain amount of other gases are mixed in, and the filling and recovery time is very short.
以上説明したように、本発明は運転状態とは異
なる気体を用いて操作試験を行なうようにしたた
め、この試験に要する時間を短縮できる。 As explained above, since the present invention conducts the operation test using a gas different from that used in the operating state, the time required for this test can be shortened.
