Problems solved by technology

[0002] At oil and gas field fracturing sites around the world, traditional fracturing equipment adopts the power transmission system configuration mode, that is, the diesel engine is connected to the gearbox to drive the fracturing plunger pump through the transmission shaft. This configuration mode has the following disadvantages: (1 ), large size and heavy weight: the diesel engine drives the gearbox to drive the fracturing plunger pump through the drive shaft, which is large in size, heavy in weight, limited in transportation, and low in power density
(2) Not environmentally friendly: Diesel engine-driven fracturing equipment will generate engine exhaust gas pollution and noise pollution during the operation of the well site. The noise exceeds 105dBA, which seriously affects the normal life of the surrounding residents.
(3) Uneconomical: Diesel engine-driven fracturing equipment has relatively high initial purchase costs, high fuel consumption per unit power during equipment operation, and high daily maintenance costs for engines and gearboxes.
In view of the fact that the global oil and gas development equipment is developing in the direction of "low energy consumption, low noise, and low emission", the above-mentioned shortcomings of traditional fracturing equipment powered by diesel engines hinder the development of unconventional oil and gas energy to a certain extent. development process
[0003] Electric drive equipment is a good solution to replace conventional diesel engine drive. In the existing electric drive technology, the power supply part of electric drive equipment is composed of multiple rectification units corresponding to multiple transformers, and each transformer is controlled by a high-voltage switch. However, in practical applications, when multiple rectifier units are required to work, corresponding multiple transformers need to be equipped on the job site, which causes the equipment on the job site to get together, and occupies a large area, consumes a lot of energy, and is not energy-saving. ,Not environmentally friendly

Abstract

The invention discloses an electric driving fracturing type power supplying semitrailer. The electric driving fracturing type power supplying semitrailer is characterized in that a high-voltage switch, a transformer and two rectifying unit sets are adopted to correspondingly drive a plurality of high-voltage converting units and a plurality of low-voltage converting units through common DC buses.The whole electric driving fracturing type power supplying semitrailer is small in size, compact in arrangement, and economic; the common high-voltage switch, the transformer and the rectifying unitsare adopted, so that the wiring of power supplying circuits can be reduced; the equipment quantity and investment output power can be decreased; and the use demand can be met.
