Intelligent current receiving system

Abstract

The invention relates to an intelligent current receiving system, which comprises a current receiver, a conducting groove, an automatic control system and other accessory devices, wherein the current receiver comprises a support frame, a guide rail, a slide table, a pre-jacking arch transmission device, a gas storage tank, an electric control box, a dragging chain and a driving mechanism, wherein the pre-jacking arch transmission device comprises an air cylinder, a rack, a gear, a rotating arm, a shaft coupler and a power receiving head component, and is integrally arranged on the slide table. The power receiving head is arranged on the top end of the rotating arm through the shaft coupler, and the conducting groove is fixedly formed in a ceiling positioned above a parking space of a station, is in a long strip shape in the longitudinal direction and is in a door shape in the transverse direction. The automatic control system controls the work states of components through obtaining the state signals of the current receiver system per se and the state signals and the control signals of an electric car, and meanwhile, charging state information is also fed back to an electric car control box. The other accessory devices comprise a positioning device, a connecting fastening and releasing device and a charging detection protection device. The intelligent current receiving system has the beneficial effects that the intellectualization degree is high, the charging process is fast and convenient, and the integral safety is good.

Description

technical field [0001] The invention relates to the technical field of current receiving for fast charging, in particular to a current receiving system for fast charging of supercapacitors in urban electric buses. Background technique [0002] Urban electric buses (hereinafter referred to as trams) have many advantages such as no emission, low noise, and environmental protection, so they are very popular. The existing power supply methods can be divided into two types: ordinary battery power supply and elevated contact wire power supply. For ordinary battery power supply methods, because the charging current cannot be large enough, the whole charging process is often too slow, and each charging time takes about 7-8 hours, and it can only be carried out at some fixed charging stations or bus terminals, so it cannot Achieve continuous operation. For the power receiving mode of the overhead contact wire, it can be subdivided into two types: the continuous power receiving thro...

Problems solved by technology

Although this structure has the advantages of simple structure and easy processing of the charging row and pantograph; there is not much control process in the charging process, and the operation or control is relatively simple, but it also has the following disadvantages: the exposed connectors, whether it is the charging row or the receiving The bow is easy to be damaged; the charging row is always charged and exposed to the outside, even if it is erected at a height of 5 meters, there are still potential safety hazards; the connection between the pantograph and the charging row is not fastened, which is suitable under the current charging current conditions. However, it will no longer be suitable for larger charging currents, and it is not suitable for solutions with larger battery capacity and faster charging speed.
