GAS INSULATED APPARATUS PARTIAL DISCHARGE DETECTING SENSOR AND DETECTING APPARATUS BY ITS SENSOR

摘要

PURPOSE: A partial discharge detection sensor of a gas insulation device and a detection device using the sensor are provided to reduce the manufacturing costs of the detection sensor using a compact and lightweight printed circuit technique. CONSTITUTION: A detection sensor (30) integrates an upper patch (40), a central patch (50), and a lower patch (60). The central patch and the lower patch are formed in a square shape. The upper patch is bonded with the central patch and is composed of a pair of circular plates (41), a connection plate (42), and a junction plate (43). The circular plates and the connection plate are formed on the central part of the central patch. The junction part is corresponded to an edge part of the central patch. The central patch is made of alloy materials having a permittivity of 2.2. The upper patch and the lower patch are composed of electric conductors (PEC).
