B&W的SQ-300 i混合自動電壓控制（AVC）是我們久經(jīng)考驗的SQ-300產(chǎn)品線的成員。基于同樣值得信賴的技術，SQ-300i混合AVC既可以控制傳統(tǒng)的單相變壓器整流器（T/R）組，也可以控制低ESP電壓紋波的三相T/R組。

正如其前輩一樣，SQ-300i混合AVC是除塵器控制系統(tǒng)的一個組成部分。它同時控制T/R裝置的電源，分析警報，并與基于計算機的數(shù)據(jù)采集軟件接口。能夠控制兩種不同類型的電源，一種已經(jīng)使用了80年，另一種是未來的發(fā)展方向，這為產(chǎn)品線增加了一個的維度。

混合設計的特點

單相和三相電源源自同一設計。它們都使用可控硅整流器（SCR）進行電源控制，都不需要主動冷卻系統(tǒng)，并且都具有很高的可靠性。有了這些相似之處，SQ-300i混合控制器的開發(fā)就自然而然地進行了。

SQ-300i混合AVC的優(yōu)勢

• 三相低紋波單相電源的單組件解決方案
• 低成本高可靠性
• 采用現(xiàn)代大規(guī)模集成組件和裝置，降低了控制尺寸和復雜性
• 簡化結(jié)構(gòu)；一個可與工廠系統(tǒng)接口的電源控制系統(tǒng)
• 備件庫存所需資源減少
• 作為升級組件的雙重功能；滿足常規(guī)控制替換的即時需求，即使T/R裝置后來升級為三相，也能繼續(xù)使用
• 自動線路電壓和控制電壓檢測
• 通過簡單的固件更改從單相切換到三相（反之亦然）

B&W’s SQ-300 i Hybrid Automatic Voltage Control (AVC) is the latest addition to our proven SQ-300 product line. Based on the same trusted technology, the SQ-300i hybrid AVC can control both conventional single-phase transformer rectifier (T/R) sets and three-phase T/R sets with low ESP voltage ripple.

Like its predecessors, the SQ-300i hybrid AVC is an integral part of the dust collector control system. It simultaneously controls the power supply to the T/R device, analyzes alarms, and interfaces with computer-based data acquisition software. Being able to control two different types of power supplies, one that has been in use for 80 years and the other that is the way forward, adds a unique dimension to the product line.

Hybrid design features

Single-phase and three-phase power supplies are derived from the same design. Both use thyristor rectifiers (SCRS) for power control, both do not require an active cooling system, and both have high reliability. With these similarities, the development of the SQ-300i hybrid controller was a natural progression.

Benefits of SQ-300i hybrid AVC
