Embodiment Construction

[0050] [0037] Exemplary embodiments according to the present invention will be explained below with reference to the drawings.

[0051] 【0038】 figure 1 is a diagram showing the structure of a three-phase and four-wire power distribution system according to an exemplary embodiment of the present invention.

[0052] 【0039】if figure 1 As shown, the three-phase and four-wire power distribution system according to the exemplary embodiment of the present invention includes four lines, specifically, the three-phase supply lines U, V, and W, the neutral line N, and the three-phase and a four-wire type transformer 1 (hereinafter, simply referred to as "balance transformer").

[0053] [0040] The balancing transformer 1 is optimally positioned on, for example, a mains or a branch line. The balance transformer 1 supplies unbalanced current flowing through the neutral line N back to one or more of the three-phase power supply lines U, V, and W, thereby making it possible to efficientl...

Abstract

The present invention relates to a three-phase four-cable power distribution system and a method for installing a balancer in the system. According to the method for installing the balancer in the three-phase four-cable power distribution system which comprises a three-phase power line and a neutral line, wherein the balancer supplies the unbalanced current flowing over the neutral line back to the three-phase power line. The method comprises the following steps: measuring the neutral line current in the line connecting the balancer; calculating the capacity of the balancer connected with the end of the line according to a maximum current in the neutral line current and a maximum voltage exerted to the line; and connecting the balancer with the calculated capacity to the end of the line.

Description

technical field [0001] [0001] The present invention relates to three-phase and four-wire power distribution systems and methods of arranging balancers in three-phase and four-wire power distribution systems. Background technique [0002] [0002] In developing countries, three-phase and four-wire systems are used as power distribution systems in which three-phase alternating current (AC) power is supplied through four wires. [0003] 【0003】 Figure 13 An example of the structure of a three-phase and four-wire power distribution system is shown. [0004] 【0004】if Figure 13 As shown, the three-phase and four-wire power distribution system includes four lines, specifically the three-phase power supply lines U, V and W and the neutral line N. [0005] [0005] When a machine that consumes relatively high power is used as a load (for example, a motor), three-phase power supply lines U, V, and W (three-phase three-wire) are used, while a device that consumes relatively low power is ...
