滑触线的特性和保养办法有哪些？

1、安全：供电滑触线外壳系由高绝缘性能的工程塑料制成。外壳防护等级可根据需要达以IP13、IP55级，能防护雨、雪和冰冻袭击以及吊物触及。产品经受多种环境条件考验。绝缘性能良好，对检修人员触及输电导管外部无任何伤害。

1, security: power supply sliding contact wire shell is made of high insulation performance engineering plastics. Shell protection grade according to the need of using IP13, IP55, rain, snow and frost protection attacks and hanging touch. The product to a variety of environmental conditions test. Good insulation properties, the maintenance personnel to reach transmission outside the vessel without any harm.

　　2、可靠：输电导轨导电怀能*，散热较快，并用电流密度高，阻抗值低，线路损失小，电刷由具有高导电性能，高耐磨性能的金属石墨材料制成。受电器移动灵活，定向性能好，有效控制了接触电弧和串弧现象。

2, reliable transmission guide: conductive with excellent, fast heat dissipation, and high current density, low impedance, line loss is small, brush with high conductivity, made of metal graphite material with high wear resistance. The appliance is and flexible, the directional property is good, the contact arc and the series arc phenomena effectively.

　　3、经济：供电滑触线装置结构简单，采用电流密度高，电阻率低，电压损耗低的铜排作为导电主体。可节电6%左右，实现以塑代钢，以塑代铜，设计新颖，无需其他绝缘结构，无需补偿线，安装于起重机控制室同侧，节省安装材料和经费，其综合费用与钢质祼滑线大致相同。

3, economic power: sliding contact line device has the advantages of simple structure, the high current density, low resistivity, low voltage loss of copper as a conductive body. Can save electricity by 6%, to plastic steel to plastic, copper, novel design, no other insulation structure, without compensation wire, installed in the crane control room with the side, save installation materials and funds, and the comprehensive cost of steel exposed slip line roughly the same.

　　4、方便：供电滑触线装置将多级母线集合于一根导管之中，组半简便。其固定支架，连接夹、悬吊装置，均以通用件供应，装拆、调整、维修亦十分方便。

4, convenient: power sliding contact line device will be set in a multistage bus duct, semi simple group. The fixed bracket, connecting clip, the suspension device, are in general parts supply, install, adjust, repair is also very convenient.

　　为了保证滑触线正常运行，延长其使用寿命，在滑触线投入运行后，应对其进行定期检修。　　1、 电刷： 应根据移动用电设备使用情况每1—3个月检查一次。重点检查集电器电刷的磨损情况，若磨损量≥5mm时，必须更换。检查时若发现电刷松动或发生磨损偏斜时，应查明原因，及时处理。

In order to ensure the normal operation of the sliding contact line, prolong the service life of the sliding contact line, after putting into operation, should carry out regular maintenance. 1, brush: electric equipment should be based on the use of every 1 - 3 months check once a. Focus on examination of the collector brush wear, if wear is greater than or equal to 5mm, must be replaced. If found loose or worn oblique brush examination, should identify the reasons, timely treatment.

　　2、 集电器：至少每季度检查一次。重点检查紧固件有无松动、移位及塑料件和活动件磨损情况，检查弹簧拉力(集电器电刷与导轨的接触压力应保持一定压力(见下表)。发现问题及时处理。

2, the collector: at least quarterly check once a. Focus on examination of the fastener without loosening, displacement and plastic parts and moving parts wear, check the spring tension (contact pressure collector brush and guide should maintain certain pressure (see table below). Found problems in a timely manner.

　　3、 连接件：至少每年检查一次。重点检查紧固螺栓、焊缝及支撑件是否松动、锈蚀、移位等，发现问题，及时处理。

3, connection: at least once a year to check. Focus on examination of the fastening bolts, welds and support is loose, corrosion, shift, found the problem, timely treatment.

　　4、 日常检查：重点检查轨道的平直度有无明显偏差(大于20mm)、错位，绝缘保护件有无脱落、断裂、破损，不锈钢“v"型槽有无翘起;轨道上有无异物及导电粉尘等。必要时应检测其绝缘电阻是否符合要求(相间绝缘电阻应≥5MΩ)。

4, the daily inspection: inspection of key rail straightness has no significant deviation (more than 20mm), dislocation, insulation protection piece off, fracture, damage, stainless steel "V" type groove is not tilted orbit; there is no foreign body and conductive dust etc.. When necessary, to detect the insulation resistance is required (interphase insulation resistance should be greater than or equal to 5M.).

　　特别对行车轨道重合度、轨距、倾斜度等偏差较大，使用频繁、车间粉尘过大、温度较高及有水、酸、碱、雾和室外使用的环境，必须加强日常检查与维护。

Especially on large track gauge, coincidence degree, gradient error, use frequently, workshop dust is too large, high temperature and water, acid, alkali, fog and outdoor environment, must strengthen the routine inspection and maintenance.
