Box type switching station

Abstract

The invention discloses a box type switching station, comprising an air-discharge device and a supervising device. The air-discharge device comprises an air-discharge duct, an air conditioner and a fan; the hot air in the switching station is discharged by utilizing the cold air in the air conditioner, and is discharged by force through the fan. The supervising device comprises a local control module and a monitoring module, wherein the monitoring module is used for collecting the temperature information, voltage information and current information in each power distribution cabinet in the box type switching station, and the working condition information of the air-discharge device, and transmitting data to the local control module; the local control module is used for controlling the starting, temperature and wind speed of the air conditioner according to received temperature information and working condition information of the air-discharge device, controlling the starting, temperature and wind speed of the fan, and receiving and displaying the voltage information and current information. Combined with the Internet of Things technology, and based on a sensor network measurement and control platform, the invention forms an intelligent box type switching station integrating various functions such as supervision, control and early warning.

Description

technical field [0001] The invention relates to the field of power transmission and distribution, and more specifically relates to a box-type switch station. Background technique [0002] The oil and gas industry usually adopts 35kV box-type switch station, 10(6)kV box-type switch station with main transformer and other equipment to form a complete set of power transmission and distribution system to meet the needs of oil exploitation. The traditional outdoor box-type switch station is a pre-installed complete set of power distribution equipment composed of high-voltage and low-voltage chambers. It is suitable for ring network, double-wire, and terminal power supply methods, and the three methods are interchangeable. Cables are used for the incoming line, and the high-voltage chamber adopts a compact design, which has the interlocking function of preventing misoperation, and is compatible with terminal load switches, air ring network switches, SF6 ring network cabinets, etc....

AI Technical Summary

Problems solved by technology

[0003] However, the existing box-type switch station has many advantages, which are increasingly unable to meet the needs, specifically:

[0004] (1) Power transmission and distribution equipment for oil exploration is often built in areas with harsh environments, especially in Northwest China due to factors such as large sandstorms, large temperature differences in summer and winter, and a large amount of alkaline dust in individual areas, so it is easy to dissipate heat and ventilate box-type switch stations The system is adversely affected, and the failure rate of the heat dissipation system is high, and maintenance is frequent; the phenomenon of burning out power distribution equipment (such as frequency converters, contactors, soft starters) due to the failure of the ventilation and heat dissipation system occurs frequently every year, which brings great impact to oil field production. indirect loss;

[0005] (2) The existing box-type switch station lacks information interaction function and auxiliary decision-making control function. At the same time, if the equipment is not operating normally, it cannot be pre-warned before shutdown. Respond and issue maintenance instructions only after failure occurs;

[0006] (3) The existing box-type switch station still uses traditional paper record information, lacks unified collection, analysis and management of information, and does not have fine management of the running time, use and replacement cycle of each component in the equipment;
