Oil-immersed high-power non-inductive resistor

Abstract

The invention relates to an oil-immersed high-power non-inductive resistor, which includes a resistance element. The laminated plate separates the stainless steel shell into an inlet chamber and an outlet chamber. The resistance element is composed of a resistance unit I and a resistance unit II which are integrated and placed in the inlet chamber and the outlet chamber. The resistance unit I and the resistance unit II are respectively along the The length direction is closely arranged in a continuous S shape and the direction of the two arrangements is opposite. The resistance unit I and the resistance unit II are respectively composed of a plurality of S-shaped resistance segments connected end to end. The outer wall of the resistance element is wrapped with Electrical paper, a set of porcelain insulating sleeves connected to the resistance unit Ⅰ and resistance unit Ⅱ is installed at the end of the stainless steel case, and the inlet chamber and the outlet chamber of the stainless steel case are filled with high temperature resistant insulating oil. The utility model has the advantages of simple structure, small volume and excellent anti-electric power performance.

Description

technical field [0001] The invention relates to a power device commonly used in the field of power transmission and distribution, in particular to an oil-immersed high-power non-inductive resistor. Background technique [0002] High-power non-inductive resistors are the most commonly used power devices in the field of power transmission and distribution. Filter resistors for UHV transmission projects, filter resistors for SVC, charging resistors for SVG, starting resistors for flexible DC transmission projects, neutral point grounding resistors, etc., all provide a wide range of markets for high-power non-inductive resistors space. [0003] With the upgrading of the transmission and distribution network, the power of non-inductive resistors is increasing. Traditional high-power non-inductive resistors are divided into cast iron resistors, grid resistors, strip resistors and mesh resistors. However, they all adopt natural air-cooled structure to dissipate heat for resistors...
