Product Description Electrical /Battery Driven-Double Power Workover RigMain parts1.Power systemThe power system adopts double-power configurationPower I: Diesel engine+gearboxPower II: AC Variable Frequency MotorThe driving power of the chassis comes from Power I; The operating power can be provided by either Power I (diesel engine) or Power II (AC variable frequency motor). By switching the transfer case, power conversion and high/low speed gear switching of the AC variable frequency motor can be achieved. At the same time, the diesel engine can also drive the drum as an emergency drive for the drawworks. The operating power and the chassis power are controlled through the operating handle set on the transfer case, ensuring that the platform operation and chassis driving are not used simultaneously, and ensuring safety and reliability during driving and operation.1.2 Power switching transfer boxThe power switching transfer case is a power input, output, and switching device that integrates a two-speed gearbox with a parallel transfer case. The function of the power switching transfer case is to input the power of the engine and drive the drawworks system on the vehicle through the power output end at the upper end; The middle power output end drives the rotary table through the transmission shaft, lower chain transmission box, and upper chain transmission box; The lower two power output end drive the chassis driving system. The motor power input end integrates high and low gear switching to meet the operational performance requirements of the drawworks and rotary table, ensuring the lifting capacity of the hook and ensuring, safety and reliability.The power of the engine and the power of the motor cannot be input into the power switching transfer case at the same time. The supplier needs to install a power input detection device in the parallel box, which can be interlocked and linked with the control system.2. Main motorThe main motor adopts explosion-proof AC frequency conversion motor, with strong overload capacity and perfect protection measures. The main cable adopts explosion-proof aviation plug-in parts. The main motor is installed by the chassis factory and equipped with motor suspension fixing bolts and drive shaft.Rated power 400kW Rated voltage 400V Rated frequency 33.5Hz3 Electronic control system3.1 Overall requirementsThe design and manufacturing of electronic control systems should adhere to the principles of "advanced, reliable, safe, convenient, economical, and HSE", with the overall performance and manufacturing quality reaching international standards. The high-voltage transformer system, variable frequency drive and control system, MCC system, various protection functions, interlock functions, etc. can meet the working needs and process requirements of the XJ1350 dual power workover rig. Adopting correct and reliable explosion-proof, shockproof, moisture-proof, and waterproof measures, in compliance with safety operation requirements.The electronic control system can operate reliably and stably at an ambient temperature of -35oC to +45oC and a relative humidity of ≤90% (+20oC), with a fault shutdown rate of less than one in a thousand.The high voltage transformer system can be connected to the 10KV, 6.3KV power grid and output AC400/50HZ.(4)The variable frequency transmission and control system adopts advanced full digital vector control, using the combination of bus technology and program control technology to connect the variable frequency transmission part and remote operation part in the workover rig system, so as to realize driller intelligent control of the drawworks.(5)The power distribution and control of the MCC system is reasonably designed to meet the requirements of AC380V/220V 50HZ electrical equipment.(6)The overall level of electric workover rig has been substantially improved(7)Three-phase five-wire power supply(TNS).No.NameQtyRemarks1Electrical control room1≤9300mmX3000mmX2900mm2Ring main unit2One set 10kV, One set6.3kV, with metering3Voltage changer1800kVA AC10kV,6.3kV/400V4High voltage cable and accessories1 5Switch cabinet1400V6Active filter cabinet1400V 100A7Drawworks frequency converter cabinet1Domestic mature brands8Touch screen1 10PLC1Siemens11Driller operation control system1Includes control buttons and handles12400V Junction cabinet1 13MCC cabinet1 14Plug-in cabinets1Including connectors (including 200A), copper bars are used for currents above 200A, and copper bars need to be protected16Main vehicle explosion-proof cabinet1(Provided by the supplier)17Integrated hydraulic station explosion-proof cabinet1≥37kw motor, Voltage-Drop Starting (including hydraulic oil tank heat tracing control) (provided by the supplier)19Lighting lamps1The main vehicle, drill floor and mast adopt DC24V.20Lighting explosion-proof control box1(provided by the supplier)21Power and control cables1Including the electrical control room and well site (low temperature), the cable from the electrical control room to the main vehicle is 40 meters, and the cable from the electrical control room to the driller's room is 60 meters.22Cable tray1From the electrical control room to the main vehicle (with a total length of 50 meters, divided into three specifications of 2m, 4m, and 6m, including 2 sets of 90°elbow cable trays, ensuring smooth contact between cables and cable trays)23Grounding system1
