Product Introduction

YNXZ串联谐振总体介绍采用多级叠加的方式,多台电抗器可并联、串联使用,分压器既用来测量试验电压,也可以作为小电容量试品的补偿电容,使得谐振频率可以在30~300Hz范围内完成多种电力设备的交流耐压试验。变频串联谐振基本原理是采用可调节(30--300Hz)串联谐振试验设备与被试品电容谐振产生交流试验电压。

YNXZ串联谐振总体介绍由变频电源、激励变压器(也可称为励磁变压器)、电抗器和电容分压器组成。被试品的电容与电抗器构成串联谐振连接方式;分压器并联在被试品上,用于测量被试品上的谐振电压,并作过压保护信号;调频功率输出经激励变压器耦合给串联谐振回路,提供串联谐振的激励功率。 变频串联谐振试验装置是运用串联谐振原理,利用励磁变压器激发串联谐振回路,调节变频控制器的输出频率,使回路电感L和试品C串联谐振,谐振电压即为加到试品上电压。变频谐振试验装置广泛用于电力、冶金、石油、化工等行业,适用于大容量,高电压的电容性试品的交接和预防性试验。

Performance characteristics

1、所需电源容量大大减小,试验所需的电源功率只有试验容量的1/Q;

2、体积小,重量轻,一般为普通试验装置的1/3-1/5;

3、谐振电源调频及功率元件使用日本的优良元器件,设计的是谐振式滤波电路,能改善输出电压的波形畸变,获得很好的正弦波形,有效预防了谐波峰值对试品的误击穿;

4、变频电源保护功能强,稳定性好;具备具备全自动(自动调谐、自动升压)、全手动(手动调谐、手动升压)以及半自动(自动调谐、手动升压及手动调谐、自动升压)的多种工作模式,可任意切换使用;操作方便;采用220V或380V单相电源,方便现场取电;

5、配置灵活,扩展功能强。谐振电抗器采用多只方式,积木式组合,可串可并,满足多种试品的试验要求,更方便现场使用;

6、大屏幕触摸LED液晶彩屏和外接鼠标直接完成各种参数的设置,试验结果可保存、打印、上传、回查等。
