Product Introduction：
Our company provides a complete set of technical solutions and engineering services for the electrification power transformation of various drilling rig networks. The overall principle of network electrification transformation is to follow the principles of reliable work, economical operation, advanced performance, convenient transportation, and meeting HSE requirements. The system, shockproof, moisture-proof, and waterproof meet the requirements for safe operation.

The electrification power transformation of the drilling rig network is mainly based on the 35KV or 10KV high-voltage power supply in the oilfield area, taking into account the geographical environment of different oil areas, high-voltage power grid layout, original drilling rig configuration, and working electricity load characteristics.

Only the power unit and electrical system (high-voltage transformer and electrical control system) of the drilling rig's backend will be electrified, and no other changes will be made.

The 35KV/0.6KV mobile high-voltage transformation and distribution system converts the power supply of the high-voltage power grid in the oilfield area into 06KV, and the asynchronous motor+hydraulic speed control box provides power for the drilling rig. The intelligent electronic soft starter starts the asynchronous motor. The 0.6KV/0.4KV/1250KVA dry-type transformer supplies power to the 0.4KV/VFD system of the drilling rig. In the power outage condition of the industrial power grid, the 400V auxiliary generator set is divided into two power supplies, one directly supplying the MCC/VFD system of the drilling rig, and the other returning to a high-voltage AC motor through a transformer. The drilling rig can perform emergency operations.


The system includes an integral sled type power unit and an electrical system designed for two power rooms, which can be lifted and towed. Meet the control requirements of mobile substations, electrical control modules, intelligent AC motor soft starters, mobile control rooms, high and low voltage cable laying, emergency power systems, etc.
