Product Description
| 1 Applicable scope |
| The Y CQD 7 series intelligent integrated star delta starter ( here in after referred to as the starter ) is suitable for three - phase squirrel cage induction motors with AC 5 0 Hz , rated voltage of 3 8 0 V / 4 0 0 V , and rated working current of up to 1 1 0 A ( phase current when the starter is delta connected ) , controlling power up to 9 0 kW . It is used to control the start , operation , and stop of the stator winding from star to de lta co nve rs io n , i n o rde r to red uce the i m pact of sta rti ng c u rre nt a nd moto r sta rti ng o n the t ra ns m iss io n netwo rk . The starter adopts a modular design and integrated structure , integrating contact or s , intelligent co nt ro lle rs , a nd a ux ilia ry co ntacts . The i nte llige nt co nt ro lle r ca n a uto matica lly co nt ro l the starter to run according to the predetermined program , there by completing the star delta starting of the motor . |

| 4 Normal working and installation conditions |
| 4.1 The altitude of the installation site shall not exceed 2000m. 4.2 The upper limit value of the normal operating environment temperature shall not exceed +40 ºC, the lower limit value shall not be lower than -5 ºC, and the average temperature value within 24 hours shall not exceed+35 ºC; When the ambient temperature exceeds the range, users need to negotiate with the manufacturer. 4.3 Vertically installed starters have power terminals facing upwards and load terminals facing downwards; The inclination angle between the installation surface and the vertical surface of all starters shall not exceed ± 5 °, which does not affect their performance. 4.4 No abnormal vibration or impact. 4.5 Pollution level: Level 3. 4.6 Fixation method: screw installation. |
| 5 Structural features and working principles |
| Star Delta Start: When the control coil is energized with a 220V control voltage, the main contactor of the product closes, forming a star circuit with the star contactor. The motor starts running at reduced voltage. When the operating time reaches the set switching time and the motor speed approaches normal speed, the main contactor automatically disconnects and then simultaneously closes with the angle contactor, forming a triangular circuit, and the motor runs at full voltage. Mechanical emergency: When the signal line or the control line of the fire pump control box malfunctions, making it impossible to automatically or manually start the fire pump, the mechanical emergency start device on the fire pump control box door can be used to manually close the main and corner contactors of the fire pump to start the fire water pump. |
