星三角啟動(dòng)器 星三角啟動(dòng)控制箱由斷路器、交流接觸器、熱繼電器、按鈕、指示燈、電壓表、電流表等組成。電機(jī)在起動(dòng)時(shí)采用星形接法，以降低繞組電壓，起動(dòng)后切換到三角形接法，電機(jī)按正常電壓運(yùn)行的一種降壓?jiǎn)?dòng)方式。該方式可有效降低啟動(dòng)電流，保護(hù)電機(jī)免受啟動(dòng)電流燒毀。
適用于11kW~75kW大負(fù)載，啟動(dòng)時(shí)間長(zhǎng)的各種型號(hào)風(fēng)機(jī)作不頻繁啟動(dòng)、停止控制。如4-72、9-19、Y5-47、C6-46大慣性離心風(fēng)機(jī)、羅茨風(fēng)機(jī)等使用。

Star triangle start control box The Star Delta Startup Control Box consists of circuit breakers, AC contactors, thermal relays, buttons, indicator lights, voltmeters, and ammeters. When the motor is started, the star connection method is adopted to reduce the winding voltage. After starting, it is switched to the delta connection method, and the motor is operated according to the normal voltage. This method can effectively reduce the starting current and protect the motor from the starting current.
Applicable to 11KW~75kW large load, various types of fans with long starting time for infrequent start and stop control. Such as 4-72, 9-19, Y5-47, C6-46 large inertia centrifugal fan, Roots
