葫芦岛干式变压器：接触调压器

接触调压器 　　
接触调压器即自耦调压器。接触调压器有单相的，也有三相的。
单相接触调压器的工作原理，与自耦葫芦岛干式变压器一样，它的铁心做成环形，绕组就绕在这个环形铁心上。二次绕组的接头是一个能够沿着绕组的裸露表面自由滑动的电刷触头，当移动电刷触头的位置时，就可以平滑地调节输出电压。三相接触调压器可由三个单相接触调压器组合而成。通常使用的自耦调压器，大容量只有几百千伏安，电压只有几百伏。
接触调压器单元容量在10kVA及以下的均为环式，单、三相容量大于30kVA的多为柱式。多个环式的单元，共轴Y联结可组成三相，共轴通过平衡电抗器并联可组成单相大容量的接触调压器。
环式的铁心卷绕成环状，截面呈正方形，柱式的铁心叠成柱状，截面呈圆形。接触调压器绕组采用纸包线或裸铜线绕制，电刷采用特制的银铜合金。柱式调压器调压过程中，电刷沿绕组绕向螺旋升成或实现连续、平稳调压，并且基本上可从零起升压。
接触调压器是不能代替安全葫芦岛干式变压器使用的，因为万一接线不合适，就会发生触电事故。若将电源相线位置接反(误将1端接地线)，尽管二次输出电压很低，但当人站在地面上触及低压侧的任一导线时，都相当于触及了上百伏的电压，将有生命危险。因此，安全葫芦岛干式变压器一定要采用双绕组葫芦岛干式变压器。

Contact with the regulator

Contact voltage regulator, auto voltage regulator. Contact with the regulator single-phase, three phase.
Single-phase cont华盈非晶合金变压器有限公司act with the working principle of the regulator, with the autotransformer, its core made ??of the ring, winding around in the ring core. The secondary windings of the connector is an exposed surface free sliding along the winding brush contact, when the location of the mobile brush contacts, you can smoothly adjust the output voltage. Three-phase contact with the regulator by three single-contact voltage regulator combination. Autotransformer, usually used with a maximum capacity of only a few hundred kVA, voltage is only a few hundred volts.
Contact voltage regulator unit capacity of 10kVA and below are ring type, single, three-phase capacity greater than 30kVA of more than for the column. Multiple ring unit, coaxial Y link can be composed of three-phase coaxial parallel balancing reactor composed of single-phase high-capacity contact the regulator.
Core winding of the ring into the ring, the cross-section was square, and column of the core quartet built cylindrical cross-section was circular. Contact with the regulator winding a wrap wire or bare copper wire brush using a special silver-copper alloy. Pole regulator regulator process, the brush along the winding around the helix or to achieve a con手 机：13287501888tinuous, steady voltage regulator, and can basically be from zero from the boost.
Contact with the regulator is not a substitute for safety transformer, electric shock occurs in case of improper wiring. If the power supply line position reversed (mistakenly one termination ground), secondary output voltage is very low, but when standing on the ground touching the low pressure side of any one of the wires are equivalent to touch hundreds of volts voltage, there will be life-threatening. Therefore, the security transformer must be two-winding transformer.
