Working principle
KB L系 列 穩 壓 器 結 構 它 由 三 相 補 償 變 壓 器、三相調壓變壓器、傳動機構、
電刷接觸系統、控制系統和箱體等組成。三相調壓變壓器圓盤式繞組外表面
經磨光加工，去除絕緣，呈光滑的導體面，以便於電刷良好接觸;傳動機構由
伺服電機、變速箱、碳刷總成組成;電刷接觸系統由壓力彈與碳刷組成，結構
合理可靠；箱體採用封閉櫃式，體積小，散熱好，面板數顯儀錶醒目，精度
高;控制 系統 採用集成電路(微電腦控制)，控制功能強，功能完善，調節方便
穩定可靠。
KB L系 列 穩 壓 器 基 本 原 理 是 當 輸 入 電 壓 高于或者低于380V時，控制取樣電
路會偵測到輸出電壓過高或者過低，系統會向調壓電機發出補償電壓命令，
帶動碳刷改變調壓變壓器的匝數比，從而改變補償變壓器一次側輸入電壓，
達到補償變壓器二次側的電壓補償V數，使輸出達到穩定380V的目的。
KBL series voltage regulator structure is composed of three-phase
compensation transformer, three-phase voltage regulating transformer, transmission
mechanism, brush contact system, control system and box. The outer surface of the
disc winding of the three-phase voltage regulating transformer is polished to remove
the insulation and form a smooth conductor surface for good contact with the brush;
The transmission mechanism is composed of servo motor, gearbox and carbon brush
assembly; The brush contact system is composed of pressure spring and carbon
brush, with reasonable and reliable structure; The box body adopts closed cabinet
type, with small volume, good heat dissipation, eye-catching panel digital display
instrument and high precision; The control system adopts integrated circuit
(microcomputer control), with strong control function, perfect function, convenient
adjustment, stability and reliability.
The basic principle of KBL series voltage regulator is that when the input voltage
is higher or lower than 380V, the control sampling circuit will detect that the output
voltage is too high or too low, and the system will send a compensation voltage
command to the voltage regulating motor to drive the carbon brush to change the turn
ratio of the voltage regulating transformer, so as to change the input voltage at the
primary side of the compensation transformer, so as to compensate the voltage
compensation V at the secondary side of the compensation transformer and stabilize
the output at 380V.
