Abstract

The present invention relates to a modular current limiting resistor comprising: a plurality of resistors which are stacked on one another, wherein the plurality of resistors each comprise a pair of coupling pieces and a conducting line integrally formed with the coupling pieces and having a zigzag shape between the coupling pieces; a pair of support frames which respectively support the stacked resistors, on both sides of the stacked direction; a plurality of coupling members which pass through one of the support frames, pass the coupling pieces, and then are inserted into the resistors through the other one of the support frames so as to fix the resistors; a plurality of conductor rings which are disposed between the plurality of resistors while passing through and being inserted into the coupling members, and which electrically connect the conducting line on each of the resistors; and a plurality of insulating rings which are disposed between the plurality of resistors while passingthrough and being inserted into the coupling members so as to insulate the resistors. At least one unit module is provided.

Description

technical field [0001] The invention relates to a modular current-limiting resistor with welding quality and easy resistance design. Background technique [0002] Usually, a current limiting resistor (CLR, Current Limiting Resistor) functions to limit a fault current (FaultCurrent). Apply current limiting resistors to power systems and limit fault currents that occur in power systems. If a current limiting resistor is used, even if a fault current occurs, it is possible to prevent electric equipment from being damaged or cut off. [0003] Since the size of resistance required varies depending on the system in which it is applied, the design of the current limiting resistor will vary depending on the size of the resistance. Next, a conventional current limiting resistor will be described with reference to the drawings. [0004] figure 1 It is a perspective view showing a conventional current limiting resistor. [0005] like figure 1 As shown, the existing current-limiti...
