Skid-mounted electronic control integrated transformer substation with voltage class of 220 kV and below

Abstract

The invention provides a skid-mounted electronic control integrated transformer substation with voltage class of 220 kV and below. A main transformer chamber and a main transformer heat dissipation chamber are arranged in the transformer substation, and the transformer substation comprises a skid body, an automatic control protection unit, an intelligent power supply unit, an operation and maintenance environment intelligent monitoring system and an intelligent equipment management service system. GIS combined electrical equipment is adopted in the high-voltage power distribution unit, a basin-type insulator is adopted to be connected with a bus, the basin-type insulator is of a double-circular shielding inner ring structure, gas sealing is conducted through double sealing rings, and design parameters in the double-circular shielding inner ring structure are determined according to preset constraint conditions and a target function. Remote control personnel can pay more attention to abnormal information and take corresponding measures more quickly, interaction between the equipment and a remote control center and between the equipment and a client is more efficient and smoother, the safety and automation level of device operation can be improved, and the system and the method are suitable for power supply and use requirements of scattered equipment in oil and gas field engineering.

Description

technical field [0001] This application relates to the field of electric control technology for oil and gas fields, and in particular to a skid-mounted electronic control integrated substation with a voltage level of 220kV and below with intelligent management functions. Background technique [0002] At present, most of the 220kV or 110kV (including the following grades) substations operating on the market are traditional civil structure or ordinary prefabricated substations. Traditional civil structure substations occupy a large area, have a long construction period, low reusability, and pollute the construction process. Seriously, for most cities with extremely tight construction land, the economic efficiency and environmental protection are extremely low; while ordinary prefabricated substations are generally only used at power supply terminals with low power supply quality requirements, and the product functions are relatively single, and generally do not have unattended ...

AI Technical Summary

Problems solved by technology

[0004] This application provides a 220kV and below voltage level skid-mounted electronic control integrated substation to improve land use conflicts, shorten the construction period, improve construction economy and environmental protection, and overcome the "unattended" in the prior art that cannot grasp the equipment in real time Due to the defects of the operation and maintenance environment, an innovative smart device management service platform is created. Users can query, monitor and process device information through the computer web terminal and mobile app terminal.
