1. Overview
DC control module is the core component to control the DC motor speed and torque. It can control series motor, shunt motor can also be controlled. It can output strong trigger pulse,Ensure fast and reliable SCR conduction, make the same load coaxial drive two motors balanced load distribution.
2. adjusting
Each drilling function has independent current limit, the turntable can be smoothly adjusted current limit. Given current with increasing features, allows smooth motor torque increases.
Speed regulator for all drilling functions are related to the assigned contact with the chain, closed the door turntable overcurrent threshold is set at 150% of the maximum current limit values. Even with a zero
Lock protection device to prevent its sudden high-speed rotation of the motor assignments. Automatic detection and control of dynamic braking inputs and exit. You can manually adjust the potentiometer assembly,
To test the output voltage SCR bridge. Each cabinet module can replaced with each other.
3. main functions:
Depending on the speed of a given size handwheel, determine the phase angle SCR conduction achieve variable speed motor.
According to the size of the load, automatically adjust the magnitude of the current in order to maintain the stability of the motor speed.
Meet the control circuit zero lock requirements.
Provide the required control circuit voltage.
Detection and control of dynamic braking.
4. the 1400 SCR drive control cabinet
Each DC drive system includes a thyristor rectifier bridge, DC control module, a cooling fan, surge suppression circuit, contactor control circuit and pulleys slip protection circuits and other devices are installed in a drive cabinet. The cabinet superior performance, high reliability, easy operation and maintenance. SCR cabinet adjustable output voltage 0-750VDC, current up 1950ADC. Upper cabinet equipped 2000A circuit breaker with undervoltage trip coil and auxiliary contacts. Installation voltmeter (0-1000VDC), ammeter (0-2000ADC) and power-on indicator on the front panel and other devices. SCR rectifier bridge with fan forced cooling. In each phase input rectifier bridge is equipped with fuses, with micro switch, which temperature sensor and line circuit breaker trip coil interlock. Micro Switch off represents the main fuse damaged. When the temperature is too high, the temperature sensor is disconnected, normally closed contact, whether the main fuse inside temperature is too high can damage or tripping the circuit breaker to trip. Cabinet install surge suppression circuitry, can weaken any spikes harm SCR element.
Each SCR cabinet can drive mud pumps, drawworks and rotary. The motor can be driven series excitation, it may also be shunt. With a series motor driving mud pump is equipped with a pulley-slip protection device.
5.ROSS HILL (ZJ70D) DC control module
DC control module is the core component to control the DC motor speed and torque. It can control series motor, shunt motor can also be controlled. It can output strong trigger pulse, to ensure fast and reliable SCR is turned on, make the coaxial drive the same load of two motors balanced load distribution. Each drilling function has independent current limit, the turntable can be smoothly adjusted current limit. Given current with increasing features, allows smooth motor torque increases. Speed regulator for all drilling functions are related to the assigned contact with the chain, closed the door turntable overcurrent threshold is set at 150% of the maximum current limit values. With a zero chain protection device to prevent its means
When equipped with high-speed rotation of the motor suddenly. Automatic detection and control of dynamic braking inputs and exit. Potentiometer assembly can be adjusted manually to test the output voltage SCR bridge. Each cabinet module can replaced with each other.
The main function:
● Depending on the speed of a given size handwheel, determine the phase angle SCR conduction achieve variable speed motor.
● according to the load size, automatically adjust the size of the current, in order to maintain the stability of the motor speed.
● Meet the control circuit of zero lock requirements.
● provide the required voltage control loop.
● dynamic braking of detection and control.
