Generator analog management
The generator cabinet houses the main diesel-generator management equipment. The flyer describes that cabinet as easy to operate, reliable, and easy to maintain.
The AC control module is the core of diesel-generator control, for the CAT 3512A, the CAT 3512B, and other diesel engines. The printed operating temperature is −30°C to 50°C. The active voltage regulation rate is less than 1%. The reactive voltage regulation rate is 3%. The frequency stability regulation rate is less than 1%. AC components are interchangeable.
Named protections are over-frequency, under-voltage, overvoltage, reverse power, and pulse loss.
SCR analog DC control
The DC module controls the conduction angle of the SCR elements. It turns a constant-voltage, constant-frequency AC supply into a continuously adjustable DC supply for stepless speed and torque control of the drawworks, mud pumps, rotary table, or top drive.
The DC control module outputs the trigger pulses for SCR conduction and balances the load between two motors on one shaft. Speed regulators are interlocked with their assigned contactors. The flyer prints a rotary-table over-current figure of 150%.
The 40D to 90D configuration table stays on SCR control.
Questions buyers ask
- What is the ROSS HILL 1400 control system?
- It is the analog generator and SCR control set for diesel-electric rigs. The AC module controls the diesel generators. The DC module fires the SCRs for the drawworks, mud pumps, rotary table, or top drive.
- Which engines does the AC module name?
- CAT 3512A, CAT 3512B, and other diesel engines. Named protections are over-frequency, under-voltage, overvoltage, reverse power, and pulse loss.
- Where is the 40D to 90D table?
- On SCR control. This page is the module flyer. The wider drive chain is drilling rig electric drive.
