产品概述 Product description

动态电压调节装置PSTN-AVC是一款先进的电压扰动治理设备，能够起到稳压，治理电压暂降、电压暂升的作用，可以对负载设备进行保护。

The dynamic voltage regulation device PSTN-AVC is an advanced voltage disturbance control device that can stabilize voltage, control voltage sag and voltage rise, and protect load equipment.

电压补偿模式（可设定） Voltage compensation mode (adjustable)

在线工作模式：bypass-CB和SCR分断，逆变器通过注入变压器对系统电压实时调节，将输出电压补偿至Un±2%。

热备工作模式：外电源正常时SCR闭合，逆变器无输出。当外电源发生电压扰动超过10%(可设定)，SCR关断，逆变器通过注入变压器对系统电压实时调节，将输出电压补偿至Un±2%。

ONLINE COMPENSATION MODE：Bypass-CB and Bypass-SCR open, the inverter through the injection transformer the system voltage real-time regulation the output compensation with an accuracy ±2%*Un (Critical application can be ±1%*Un).

OVER-LIMIT COMPENSATION MODE：When the voltage disturbance less than 10% Un (confi gurable), Bypass-SCR closed, the INVERTER does not regulate the system voltage, while the grid voltage swell more than 10% UN, SCR open, the inverter output standard voltage through injection transformer, the system voltage real time regulation the output compensation with an accuracy ±2%*Un (Critical application can be ±1%*Un).

检修/旁路模式 BY PASS/MAINTENANCE

装置检修时，检修开关闭合，输入输出开关断开，负载设备供电正常，PSTN-AVC本体完全处于电气隔离状态，进行检修维护工作。

Close the Bypass-CB before maintenance and disconnect the disconnecting switches at both incoming and outgoing ends. The grid power will supply the load device and main body of PSTN-AVC is completely electrically isolated.

合理布局 Rational layout

根据客户用电设备对电压波动的敏感程度和设备在工业流程中的重要程度，以及关键设备在配电系统中的排列方式、数量和安放的位置不同，PSTN-AVC为您提供了在负载侧治理和在母线侧治理的灵活接入方式和母线侧集中治理的灵活接入方式。

Based on the sensitivity of customer electrical equipment to voltage fluctuations and the importance of the equipment in industrial processes, as well as the arrangement, quantity, and placement of key equipment in the distribution system, PSTN-AVC provides you with flexible access methods for load side management and bus side management, as well as flexible access methods for centralized bus side management.
