ODM 24KV 38PF Live Line Capacitors , High Voltage Ceramic Capacitor 3.6KV 40.5KV

ODM 24KV 38PF Voltage Indicator High Voltage Ceramic Capacitor 3.6KV 40.5KV rod ceramic capacitor for lightning arrestor

Theory

       In its simplest form the Live-Line Indication consists of a high voltage ac rated capacitor which is connected in series with the neon indicator between the phase and earth lines. (Fig.1) The addition of higher value, low voltage rated capacitor in parallel with the neon is sometimes preferred. (Fig.2) The object is two-fold - firstly to advise the operator that the connections are live and secondly for operation of re-routing systems in the event of inadvertent disconnection.

Application 

       To indicate the presence of voltage and for fault detection on power frequency high voltage distribution switchgear (6.6kV-36kV systems).The capacitor is connected directly to the HV line and a small current (low voltage signal) is passed which illuminates a neon lamp mounted on the front panel of the switch. Alternatively the low voltage signal may be used to feed a sensing circuit which monitors for supply failure and circuit condition. The capacitor is normally contained within a resin moulding. Usually the moulding is made by the switch manufacturers themselves in a shape to suit their own particular needs but we can offer certain complete mouldings or can advise on suitable sources.

COMPANY OVERVIEW

    Xian Xiwuer Electronic & Info. Co., Ltd. located in Beiguan , Xi'an City, covering an area of 4000 square meters, the existing staff of 2300 people, about 580 technical personnel, including 135 engineers, senior engineers 21 people. The company's total assets of 315 million yuan, fixed assets of 137 million yuan, is a large-scale enterprise mainly engaged in the production of electronic components. The company has the largest production scale of varistors, surge protectors and high voltage ceramic capacitors in China, and the main products are as follows:
