Star Triangle Start Control Cabinet

Star Triangle start control cabinet Product features: Star Triangle start control cabinet with overload, short circuit, lack of phase protection and pump body water leakage, motor overtemperature and leakage and other protection functions and complete status display, and has a single pump and multi-pump control mode, a variety of main and standby pump switching modes and various starting modes.

1, with over current, over voltage, under voltage, lack of phase protection and accident alarm function

2, excellent quality: careful international and domestic brand electrical components and high quality standard cabinet, carefully designed, seiko production.

3, diverse functions: from one control to one control five, the main and standby pump arbitrary combination, a variety of starting modes, various control forms. Automatic failover. It can also be specially designed for you.

4, control mode: (1), liquid level control: the change of liquid level as the control target; (2) Pressure control: take pressure change as the control goal;

5, switching mode: (1), manual switching; (2) Automatic alternating switching; (3), timing automatic switching.

6, starting mode: Star-triangle buck start: start the motor stator winding is connected to the "Y" shape to reduce the voltage and current of each phase winding, and the motor stator winding is restored to the "△" shape during operation.

7, starting performance: (1) Starting motor is Y connection, then the motor spindle winding voltage in the starting has been reduced to 57.7% of the rated voltage, the starting current is only 1/3 of the rated current of the motor. After starting, when the speed increases to 80% of the rated speed, it is converted into "△" shape connection operation, and the conversion time is adjusted by the time relay. (2) This product is intermittent long-term working system, can also be repeated short-time work, in the repeated short-time work, can be frequently operated no more than 30 times per hour. The interval between two consecutive starts is not less than 2 minutes.

Star triangle start control cabinet Technical parameters: Star Triangle start control cabinet control motor power: 15-90KW; Control voltage: 380V; Number of control pumps: 1-5.

Star Triangle start control cabinet is widely used: Star Triangle start control cabinet can be widely used in industrial and agricultural production and all kinds of building water supply, drainage, fire, spray pipe network pressurization and HVAC cold and hot water circulation and other occasions of automatic control, control motor power range of 15 ~ 90KW.

Star Triangle start control cabinet installation environment: "Star Triangle" step-down starting control cabinet is mainly used for AC 50Hz or 60Hz, rated working voltage to 380V, in the AC-3 use category, rated working current to 95A circuit, as the motor to start, the starter is equipped with air delay head, can automatically "star triangle" conversion, to reduce the motor starting current.
