Abstract

(57) [Summary] This bulletin contains application data before electronic filing, so abstract data is not recorded.

Description

[Brief explanation of drawings]

1 to 3 show a conventional device, where FIG. 1 is a circuit diagram, FIG. 2 is a block diagram of the entire device, and FIG. 3 shows a specific structure of a resonant axle and a protective gap. FIG. 4 is a schematic diagram showing an embodiment of this invention, and FIG. 5 is a schematic diagram showing an example of the structure of a connecting terminal constituting the main part of this invention. In the figure, 2 is the main capacitor, 3 is the voltage dividing capacitor, 4 is the potential transformer, 5 is the resonant handle, 6 is the protection gap,
51 is an iron core of the resonant axle, 52 is a coil, 54 is a connection terminal, and 16 is a molding material. Note that the same reference numerals indicate the same or equivalent parts.

Claims (1)

[Claims for Utility Model Registration] 1. An instrument transformer to which the divided voltage of a series capacitor is applied, a resonant axle connected in series to the primary side of this instrument transformer, and a parallel connection to this resonant axle. In a capacitor type potential transformer device having a protective gap, each of the pair of connecting terminals of the resonant accelerator has a portion that can constitute a protective gap and a portion that can constitute a connecting terminal, and the surface connecting terminal is A capacitor-type potential transformer device, wherein portions that can form the protective gap face each other at a predetermined position to form a predetermined protective gap. 2. The capacitor-type instrument transformer device according to claim 1, wherein the resonance axle is a molded type in which an iron core, a coil, and a connecting terminal are integrally molded.
