產品特征

1.調頻及功率元件使用*日本進口的優質元器件；
2.充分利用公司現有資源，*獨立自主開發和設計及生產該設備的所有組成部分：變頻電源、勵磁變壓器、高壓電抗器、電容補償器和高精度電容分壓器；
3.具備全自動（自動調諧、自動升壓）、全手動（手動調諧、手動升壓）以及半自動（自動調諧、手動升壓及手動調諧、自動升壓）的多種功能，可任意切換使用；
4.具備試驗電壓、加壓時間、報警電流整定、報警電壓整定、頻率范圍、起始電壓的設置；
5.具備放電保護功能，在試品發生閃絡時，或其他原因造成的諧振回路突然失諧，變頻控制電源立即自動快速切斷輸出，并顯示保護類型和閃落電壓值；
6. 測量顯示輸出電壓、輸出頻率及加壓時間、保護動作類型等相關信息，在試驗完成時電壓自動下降到零位；
7.大液晶全中文界面平臺技術，全觸摸屏操作,數據保存.
8. 技術特點要點歸納：
1. *數字、功率技術：功率器件采用國外推出的集驅動、保護和功率變換為一體的智能功率模塊（IPM），極大的提高了整機的可靠性，減少了體積和重量。
2. 完備的保護功能：
過電壓保護：保護值可設置，動作時間小于1 毫秒；
雙重過電流過熱保護：大功率器件自身保護和軟件保護相結合，動作時間小于10 微秒；
閃絡保護：動作時間小于1 毫秒，并可記錄下閃絡電壓值；
零位保護：零電壓啟動。
3. *的四種工作模式：
手動試驗：手動尋找諧振點并手動升壓到所需電壓，按鍵后自動計時；
自動試驗：根據設置自動尋找諧振點后自動升到設定電壓后自動計時；
自動調諧手動升壓：根據設置自動尋找諧振點后，需手動升電壓到所需的電壓值，按“自動計時”鍵后自動計時；
手動調諧自動升壓：手動尋找諧振點，根據設置自動升壓后自動計時。
4.友好的人機接口：
的DSP 顯示平臺，大容量的數據存儲器，大屏幕LCD 顯示；
豐富的幫助應用信息，幫助你現場分析試驗發生保護動作時可能出現的問題；
可保存200 次測試數據;
具有調頻時顯示頻率－電壓波形曲線，直觀的觀察到是否尋找到諧振點；
掃頻范圍可以在規定范圍內任意設定，掃頻方向可以向上向下任意選擇，方便用戶操作；
對于那些需要在50Hz 條件進行試驗的試品（比如發電機），我們采用了調頻調感技術，我們的電抗器電感值可以根據試驗需要進行適當調節，壓緊裝置可以保證降低在通電時電抗器的噪音；
5.*的結構設計：調頻電源控制箱的接入和輸出采用插接和螺絲連接兩種方式，安全、方便、可靠、美觀精致；
電抗器采用*的環氧澆注工藝，防潮防顛震；
整體(ti)色彩和外型由專(zhuan)業的設(she)計公司專(zhuan)門設(she)計，美觀大(da)方。
