The Wuxi KEMEI Electric sliding electric shock device patented technology Introduction

Security trolley line alternative old-fashioned Jiaotie mobile conductive device is now generally accepted by the majority of users. The trolley line refers to the trolley line body and supporting the use of collector assembly, usually user awareness of the quality of the trolley line is often confined to the body, while the collector is a consumable, with the bad ones can. This understanding mask collector in the end-of-life carbon brushes wear great hidden facts. In this paper, by the analysis of the collector, the new understanding of the importance of the collector, and to propose solutions. Wear unforeseen safety trolley line now mostly using the collector brush and conductive surface pressed contact, by frictional sliding achieve continuous power supply. The brush wear speed, the amount of wear and the wear and tear ultimate moment, with the frequency of use of the trolley line, systems of work, work environment, conductive surface roughness and pressure size and other factors, it is not monitored. This carbon brush wear the ultimate after unforeseen power outage has been set electrical use to solve the problem. Wear the ultimate hidden the collector trolley line in the effective carbon brush wear within the power supply is normal. Brush wear Ultimate, from static to see the lack of spring tension, the pressure is almost no resistance, poor contact. Carbon brush with conductive collector from dynamic look, wear is gradual, and work in a state of motion, even jog state, thus starting current, coupled with the movement of the vibration, the trolley line installation defects, deformation and other factors so surface touch-like non-contact, resulting in a strong spark burned collector black, carbon brush box deformation, increase trolley line conductive surface friction coefficient, affect the electrical conductivity. If the first collector life of one year, and thereafter, due to the rough conductive surface, coupled to the lifting of such a large current of the mechanical working environment after sequel electrical life will become increasingly shorter. Uses proven trolley line, regardless of the carbon brushes wear the ultimate hidden, the consequences will be serious collector design only consider collector.
