摘要： A high voltage capacitor includes a pair of capacitors; a common conductor, and a pair of individual conductors. Each of the pair of capacitors includes an element body having a columnar shape with a first direction as an axial direction, and including a first side surface and a second side surface facing away each other in a second direction orthogonal to the first direction, a first electrode disposed on the first side surface and electrically connected to a corresponding individual conductor of the pair of individual conductors; and a second electrode disposed on the second side surface and electrically connected to the common conductor. The pair of capacitors is disposed in such a way that the first electrodes face each other in the second direction. The common conductor surrounds the pair of capacitors and the pair of individual conductors when viewed from the first direction.

摘要： The insulating member is integrated with only one of the busbars by insert molding in which one of opposing plate members in either one of the busbars is used as an insert target. The insulating member includes an insulation active portion, a reinforcing portion and a connecting portion. The insulation active portion is disposed on a back-surface side of one of the opposing plate portions and is interposed between the back-surface side and the other one of the opposing plate portions. The reinforcing portion is disposed on the front-surface side of the one of the opposing plate portions. The connecting portion serves to connect the insulation active portion and the reinforcing portion into an integral unit. In the insulating member, lower end regions of the insulation active portion, reinforcing portion and connecting portion, which are close to the capacitor element and extending from an upper-surface side to a lower-surface side of a side plate portion, are embedded in a mold resin that covers the side plate portion.

摘要： A vacuum-capacitor-type instrument voltage transformer (1) is equipped with a main capacitor (2) and an insulating tube (3) that accommodates the main capacitor (2). A voltage dividing capacitor (4) is connected to the main capacitor (2) in series. The main capacitor (2) is equipped with a plurality of vacuum capacitors (2a) to (2c) that are connected in series. A high-voltage-side electrode (6) is provided on a high-voltage side of the insulating tube (3), and a ground-side electrode (7) is provided on its low-voltage side. The high-voltage-side electrode (6) is equipped with a high-voltage shield (8). Electrostatic capacity of the vacuum capacitor (for example, the vacuum capacitor (2a)) disposed on the high-voltage side is set to be greater than electrostatic capacity of the vacuum capacitor (for example, the vacuum capacitor (2b)) disposed on the low-voltage side.
