一、概述 8K型机车辅助回路供电电源,采用了静止变流器装置,该装置为交一直一交变流器,可将机车上的单相交流整成直流再逆变成三相工频交流(380伏)取代了旋转劈相机。该变流器由以下几部分组成:(见图1) 1.一个半控整流器,GG 2.Lz、Cz滤波器。(中间电路) 3.二个三相变流器WR_1、WR_2。WR_1为变频变压逆变器(v.v.v.f)。WR_2是恒频恒压逆变器(c.v.c.f)。 4.控制调节整流器与逆变器用的电子装置。 5.外壳、母线及脉冲变压器、电流互感器等。其整流器部分采用单相半控桥,中间
First, an overview 8K locomotive auxiliary circuit power supply, using a static converter device, the device is to pay a direct current converter, the locomotive can be integrated into a single-phase DC and then into a three-phase AC inverter (380 volts) replaced the rotating split-phase camera. The converter consists of the following components: (see Figure 1) 1. A half-controlled rectifier, GG 2.Lz, Cz filter. (Intermediate circuit) 3. Two three-phase converters WR_1, WR_2. WR_1 is a variable frequency inverter (v.v.v.f). WR_2 is a constant frequency constant voltage inverter (c.v.c.f). 4. Control and regulate the rectifier and inverter electronic device. 5. Shell, bus and pulse transformers, current transformers and so on. The rectifier part of the single-phase half-control bridge, the middle
