Abstract
The utility model relates to a resistor, in particular to a chromel non-inductive resistor, which comprises a bracket, one to two porcelain tubes equipped on the bracket, and an insulating gasket arranged between the porcelain tube and the bracket. The porcelain tube wherein is centrally provided with mutually opposite threaded grooves. Chromel wires are coiled in the threaded grooves. A distance between an outgoing plate and the bracket is no less than 30 to 40mm. The utility model solves the problems of the existing resistor of large volume, easy rusting, lower voltage resistance, and inductance reactance.
Description
Technical field
The utility model relates to a kind of resistor, particularly chromium nickel noninductive resistor.
Background technology
At present, the resistor that applies to the intelligent ground compensation pressure limiting device of 6-66KV ZTID series is a ZX series resistance device.This resistor adopts iron, chromium, Mo, and it easily gets rusty, volume big, induction reactance is arranged, contact is many, easily open a way, poor reliability.And, the application of this resistor in the intelligent ground compensation pressure limiting device of 6-66KV ZTID series to control circuit in the resonance point influence bigger, it is also low that it is withstand voltage.
The utility model content
The purpose of this utility model just is to provide a kind of chromium nickel noninductive resistor, its solved existing resistor volume greatly, easily get rusty, withstand voltage low, problem that induction reactance is arranged.
The purpose of this utility model is achieved through the following technical solutions: the utility model by support and be fitted in one to two earthenware on the support and be located at earthenware and support between insulation cushion constitute, earthenware offers reverse each other thread groove respectively from the middle, coiling chrome-nickel line in the thread groove, the distance between lead-out tablet and support is not less than the 30-40 millimeter.When above-mentioned earthenware was made as two, the chrome-nickel line was made as series connection on two pipes.
After the utility model adopts said structure, owing on earthenware, establish positive and negative thread groove, the chrome-nickel line is formed during coiling just rewind on this pipe to, it has just constituted noninductive resistor like this, eliminated the influence of induction reactance to circuit, pad is established insulating barrier between earthenware and support, and makes lead-out tablet and set spacing＞=30-40mm, it makes, and the utility model is withstand voltage to satisfy circuit requirement with creepage distance, withstand voltage ten thousand volts of 1-2.Adopt the chrome-nickel line, its resistivity height, overload are good, make the utility model a lot of than existing resistor volume-diminished, and this resistor interface is few in addition, lead-out wire employing brazing, reliability height.
