星三角启动器
产品概述:星三角启动控制箱由断路器、交流接触器、热继电器、按钮、指示灯、电压表、电流表等组成。电机在起动时采用星形接法，以降低绕组电压，起动后切换到三角形接法，电机按正常电压运行的一种降压启动方式。该方式可有效降低启动电流，保护电机免受启动电流烧毁。
适用范围:适用于11kW~75kW大负载，启动时间长的各种型号风机作不频繁启动、停止控制。如4-72、9-19、Y5-47、C6-46大惯性离心风机、罗茨风机等使用。 -
Star triangle start control box
Product Overview: 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.
Scope of application: 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
