Performance characteristics
DZTK-ZL-×××/P DC main console is the control core of the DC hoist control system. It adopts Siemens S7 series (S7-200 or S7-300) programmable controller with advanced technology and reliable performance. The speed control cabinet composed of the all-digital SIMOREG DCM 6RA80 produced by Siemens or the DCS800 DC speed control device produced by ABB can complete the drive of the DC motor, the control of the lifting condition and the necessary electrical protection by means of constant magnetic field armature commutation. Features.
The equipment has seven characteristics, such as full digitization of process control, two-wire safety loop system, system modularization, real-time display of color touch screen data, language fault alarm, programmed control process, and emergency start-up. Real-time monitoring requirements for digital mine communication and data acquisition are realized by adding corresponding communication modules.
DZTK-ZL-×××/TS DC speed control cabinet
Purpose
The DC speed control cabinet is the key equipment in the control of the DC hoist, which is used to adjust and control the speed, current and torque of the DC motor. Siemens SIMOREG DCM 6RA80 or ABB DCS800 DC speed control device is used to drive the motor with a constant magnetic field and armature commutation.
Features
All digital logic non-circulating thyristor rectifier equipment is used to form the main circuit power supply, and all control functions are completed by parameter setting; the parameter settings of the speed regulator and current regulator are automatically optimized by the system; the current speed double closed-loop control can realize four-quadrant operation, Meet various control requirements. The main circuit has various configurations such as 6-pulse, 12-pulse in parallel and 12-pulse in series, and has the function of armature overvoltage absorption. The parallel 12-pulse system with a single device and 6-pulse operation can realize full-speed and half-load operation; the series twelve-pulse system with a single device and 6-pulse operation can realize half-speed and full-load operation.
DZTK-ZL-×××/LC DC excitation cabinet
Purpose
The DC excitation cabinet is the supporting equipment in the DC lifting electric control. It adopts Siemens SIMOREG DCM 6RA80 or ABB DCS300 DC speed control device to provide constant excitation power supply for the DC motor.
Features
The two excitation devices have dual excitation switching function, excitation overvoltage protection, excitation current detection and other protection functions.
