Series of Harmonic Eliminator Resistors
1. Overview
Series ~ Nonlinear Resistor Harmonic Eliminator Damper for Neutral Point of Voltage Transformer (referred to as Primary Harmonic Eliminator ), is installed on the primary winding of a voltage transformer (hereinafter referred to as voltage transformer or transformer). A nonlinear resistor harmonic damping device between the wiring neutral point and the ground. The harmonic eliminator uses C with excellent electrical properties and ultra-fine particles as the base material. It is pressed into a high-density rectangular or round cake-shaped body by a large-tonnage press. It is then sintered at a high temperature of thousands of degrees in a reducing atmosphere. become. The surface structure of the exposed resistor has been specially treated to withstand the sun and rain, and can be used directly indoors and outdoors. Its small size, light weight, fast heat dissipation, high strength and easy installation make it very popular among users.
This product fully complies with the provisions of Article .. of the current Ministry of Electric Power Standards/"Overvoltage Protection and Insulation Coordination of AC Electrical Installations", and can have a good effect in limiting the ferromagnetic resonance of voltage transformers.

< br/> According to the system voltage classification, the series of harmonic elimination resistors are divided into three types: It is a cylindrical harmonic eliminator. Type I and type II harmonic eliminators are divided into two types: harmonic eliminator and harmonic eliminator. Type III harmonic eliminator is divided into three types.
For example: II is a system-wide, weakly insulated, cylindrical primary harmonic eliminator.
3. Conditions of use
Suitable for indoor and outdoor use, ambient temperature ℃～+℃
Rated frequency: ~>
, the altitude is not greater than, earthquake rupture degree and below areas
, places without serious pollution and corrosive media in the atmosphere>
, connected in series with AC ~ non-effective grounding Between the neutral point of the primary winding of the system and the ground, when there are multiple voltage transformers connected in a system, a harmonic eliminator should be installed at the neutral point of the three-phase high-voltage winding of each transformer. Only in this way can the arc ground overvoltage and ferromagnetic resonance be effectively limited.
