Introduction of main products

1.AC CONTROL MODULE

The Generator Unit controls the engine/generator set todevelop a constant AC supply.The output of several generators generators are fed to a commom AC bus.

Each Generator Unit's AC Control Module has an electronic engine governor,a voltage regulator and a ciecuit breaker.

The circuit breaker is interlocked with a Protection circuit which automatically trips the breaker for ,malfunctions such as overcurrent,overvoltage, under/overfrequency and reverse power.

2.DC CONTROL MODULE

Features of the DC module:SCR firing circuits with “hard-firing”outputs to ensure positive SCR turn on High-speed current regulator with twenty millisecond response 

Automatic load sharing for motors driving the same shaft,when they are driven from separate armature supplies.

Each drilling function has independent current limit,factory adjusted,no rig setup required.

Rotary Table and Power Swivel current limit continuously variable through a potentiometer mounted in the Driller's Console.

Drawworks current reference is ramped to provide for smooth of increase in motor torque.

Motor speed regulator for all drilling functions interlocked with related assignment contactors.

Over current gate suppression set at 150% of largest current limit

Zero throttle interlock,a safety    feature,prevents accidental motor power up on assignment

Manual bridge phase up for testing purposes

Fault finder meter for troubleshooting possible control logic ＆speed reference problems

3. POWER LIMIT CONTROLLER

The Power Limit System will monitor the KW(engine loading) and KVA(generator loading) of each engine-generator set.If either of these parameters approaches its rated load limit,a signal will be sent to the DC drilling Drives causing them to reduce their output.
