The double-slider current collector has the advantages of simple structure and low cost, and is suitable for popularization and use in various places with trolley conductors.
Description
Technical field
The utility model relates to and moves power consumption equipment and the fixing electrical connection arrangement between the power-supply trolley line, is specifically related to a kind of double-slider current-collector device with the short-circuit protection of job-hoping.
Background technology
Electrical connection arrangement between domestic mobile power consumption equipment and the fixing power supply slip generally has conduction connected modes such as cable drum conduction, cable coaster, drag chain, trolley current-collector at present; Wherein trolley current-collector electrically conducting manner is used very extensively, particularly is applied in big electric current, the high-tension connection.Trolley current-collector electrically conducting manner mainly is divided into three kinds in safety sliding contact line and its made-up set electrical equipment, rigid body trolley and its made-up set electrical equipment, angle steel trolley and its made-up set electrical equipment.
For guaranteeing its conduction reliability and avoid in short-term phase shortage that current-collector generally adopts two brush (slide block) structures, and adopts spring compression between slide block and the support to the infringement of rear end electric equipment; The relative speed of service between segment set electrical equipment and the trolley reaches 100 meters/minute the soonest, even higher; The trolley guide rail is to save by one to assemble, and in installation process, there are certain error in horizontal direction or vertical direction; The general design standard regulation of distance between phase and phase is nearer; Be 350mm; And because of the distance of current-collector two conductive sliders greater than reasons such as 350mm; The single slide block of current-collector exists the phenomenon of jumping out its corresponding slip and sliding into other slip, and this kind phenomenon also repeatedly takes place in actual use, causes phase fault.If what adopt is traditional two brush current-collectors, can not in time break off after the short circuit, it is excessive to make trolley bear electric current, burns out slip and maintenance isolating switch easily, even burns out transformer; The power consumption equipment phase fault burns out stube cable, circuit element easily, even causes electrical control cubicles on fire, endangers very big.
Traditional double-slider current collector structure figure is as shown in Figure 1.In the course of the work; Jump out the slip corresponding and when sliding into other slip when one in two slide blocks with it; Article two, slip just through the current-collector conducting, causes phase fault, because the electric current that passes through on the slip is generally big electric current; This short circuit very easily causes huge injury, even burns out slip, maintenance isolating switch, supply transformer.
There are many deficiencies in the prior art, in order to solve the problem that exists in the prior art, necessaryly improve design.
The utility model content
When being directed on wherein slip that slides into other phases of two conductive sliders of current-collector of same phase; Traditional current-collector itself can not be with breaking off between two slide blocks; Can not be with the problem of breaking off that is connected of this current-collector and power consumption equipment, the utility model proposes a kind of double-slider current-collector device of novel band job-hopping short-circuit protection, when the current-collector job-hopping taking place cause phase fault; Can cut off three-phase current rapidly, protect whole slipping contact wire device.
The technical scheme that the utility model adopts is: a kind of double-slider current-collector device with the job-hopping protection; Comprise collector-block; The current-collector support, fuse and current-collector internal connection line road is characterized in that: fuse is installed on the current-collector support or is installed near the collector-block; Be connected through current-collector internal connection line road between collector-block and the fuse, insert current-collector from the conductive melt rear end of fuse to the power supply of power consumption equipment.
Said fuse has Alarm contactor output.
Said current-collector internal connection line road can be made up of insulativity high flexible cable or soft copper whip, and each bar electric wire leaves certain surplus.
The beneficial effect of the utility model is: with respect to traditional double-slider current-collector; When sliding into the phenomenon of other slip taking place slide block to jump out slip corresponding with it; The utility model not only can break off the short-circuit loop between two slide blocks immediately; And can this current-collector and power consumption equipment be isolated; Avoid phase fault and to make trolley bear electric current excessive and burn out trolley, maintenance isolating switch, transformer etc., avoid phase fault simultaneously and burn out the stube cable etc. of power consumption equipment, even cause heavy losses such as electrical control cubicles is on fire.In addition, the utlity model has characteristics simple in structure, with low cost, be adapted at each trolley occasion and promote the use of.
