摘要： PURPOSE:To eliminate a blind operation and reduce mental burden of assembly operators by a method wherein it can be visually recognized that a high voltage coil connection wire does not come out of a high voltage shielding cylinder. CONSTITUTION:When an insulation spacer 9 is mounted on a metal container 5, the length of a high voltage coil connection member 17 is determined in the following manner. A position where a connection part 17a between a tip of the high voltage coil connection member 17 and a high voltage coil connec tion wire 11 is inserted a little into an inlet of a high voltage shielding cylinder 3b is determined. A distance between that position and the surface of a flange 5a of the metal container 5 is defined as the dimension X. The distance between the surface of the flange 5a and an end surface of a fitting bolt 12 of a cover 8 fitted to the insulation spacer 9 is defined as the dimension Y. The distance between the end surface of the fitting bolt 12 and the connection part 17a is determined as the dimension L. Then the length of the high voltage coil connec tion member 17 is so determined as to conform to the conditions, L>O and Y-X

摘要： PURPOSE:To prevent entrance of the external air into an exclusive tank even in case a pressure tank is opened, by providing an exclusive tank having a hermetically sealed structure which is resistive to a little pressure difference and valves communicating with internal and external sides and also providing a gas insulated potential transformer. CONSTITUTION:A gas insulated potential transformer 3 is previously filled with insulation gas and is stored under the condition that an automatic valve 7 is closed. At the time of assembling, the transformer 3 is housed together with an exclusive tank 2 within a pressure tank 1. After the assembling of interior, the tank 1 undergoes sealing, vacuum exhaustion and supply of gas. Namely, in the case of vacuum exhaustion, the valve 7 operates and opens depending on a pressure difference between internal and external pressure. Therefore, an excessive pressure difference is not applied on the tank 2. For the supply of gas, the valve 7 operates and opens depending on the pressure difference when the tank 1 is filled with the insulation gas, the insulation gas flows into the tank 2 from the tank 1, not generating an excessive pressure difference. Thereby, the transformer 3 holds initial insulation performance and it is enough for the tank 2 to have the sealed structure which is resistive to an internal and external pressure difference of about 0.3-0.4kg/cm .
摘要翻译：目的：为了防止外部空气进入专用水箱，即使在打开压力罐的情况下，通过提供具有阻力小的压力差的气密结构的专用油箱和与内部和外部相通的阀也可以提供气体绝缘电位变压器。构成：气体绝缘电压互感器3预先填充有绝缘气体，并在自动阀7关闭的条件下储存。在组装时，变压器3与专用箱2一起容纳在压力罐1内。在组装内部之后，箱1经历密封，真空排气和供应气体。也就是说，在真空耗尽的情况下，阀7根据内压和外压之间的压差而运行和打开。因此，不会对罐2施加过大的压力差。为了供给气体，阀7根据当罐1填充有绝缘气体时的压差而动作开启，绝缘气体流入槽2 来自罐1，不产生过大的压力差。因此，变压器3保持初始绝缘性能，并且足以使罐2具有耐大约0.3-0.4kg / cm 2的内部和外部压力差的密封结构。

摘要： PURPOSE:To offer the titled device of small size and low cost excellent in withstand voltage characteristic by a method wherein an insulation member with a relative dielectric constant at least of 3 is arranged between a high- tension coil and a high-tension shield. CONSTITUTION:The insulation member 10 is made of a synthetic resin such as a shieldform rubber or vinyl chloride, so-called a plastic member, and is flexible, expandable-contractable, and soft. This member is high in insulation durability with a relative dielectric constant of 3 or more. The gap formed by the opposed surfaces of the high-tension shield 9 and the high-tension coil 3 and an insulation member 4 is formed with this sheet insulation member 10, and they are formed in such a manner that the inside of the high-tension shield 9 comes in adhesion to the high-tension coil 3 and the insulation member 4 that are opposed to it. The part filled with the insulation member 10 becomes less charged with voltage, resulting in the reduction in electric field stress; therefore, this part improves in withstand voltage performance against the invasion of high voltages of high wave-front steepness. Reduction in size of the high-tension coil is enabled, and the whole gas PT can be reduced.
