滑觸線的特性和保養辦法有哪些？

1、安全：供電滑觸線外殼系由高絕緣性能的工程塑料制成。外殼防護等級可根據需要達以IP13、IP55級，能防護雨、雪和冰凍襲擊以及吊物觸及。產品經受多種環境條件考驗。絕緣性能良好，對檢修人員觸及輸電導管外部無任何傷害。

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：輸電導軌導電懷能*，散熱較快，并用電流密度高，阻抗值低，線路損失小，電刷由具有高導電性能，高耐磨性能的金屬石墨材料制成。受電器移動靈活，定向性能好，有效控制了接觸電弧和串弧現象。

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、經濟：供電滑觸線裝置結構簡單，采用電流密度高，電阻率低，電壓損耗低的銅排作為導電主體。可節電6%左右，實現以塑代鋼，以塑代銅，設計新穎，無需其他絕緣結構，無需補償線，安裝于起重機控制室同側，節省安裝材料和經費，其綜合費用與鋼質祼滑線大致相同。

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：供電滑觸線裝置將多級母線集合于一根導管之中，組半簡便。其固定支架，連接夾、懸吊裝置，均以通用件供應，裝拆、調整、維修亦十分方便。

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.

　　為了保證滑觸線正常運行，延長其使用壽命，在滑觸線投入運行后，應對其進行定期檢修。　　1、 電刷： 應根據移動用電設備使用情況每1—3個月檢查一次。重點檢查集電器電刷的磨損情況，若磨損量≥5mm時，必須更換。檢查時若發現電刷松動或發生磨損偏斜時，應查明原因，及時處理。

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、 集電器：至少每季度檢查一次。重點檢查緊固件有無松動、移位及塑料件和活動件磨損情況，檢查彈簧拉力(集電器電刷與導軌的接觸壓力應保持一定壓力(見下表)。發現問題及時處理。

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、 連接件：至少每年檢查一次。重點檢查緊固螺栓、焊縫及支撐件是否松動、銹蝕、移位等，發現問題，及時處理。

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、 日常檢查：重點檢查軌道的平直度有無明顯偏差(大于20mm)、錯位，絕緣保護件有無脫落、斷裂、破損，不銹鋼“v"型槽有無翹起;軌道上有無異物及導電粉塵等。必要時應檢測其絕緣電阻是否符合要求(相間絕緣電阻應≥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.).

　　特別對行車軌道重合度、軌距、傾斜度等偏差較大，使用頻繁、車間粉塵過大、溫度較高及有水、酸、堿、霧和室外使用的環境，必須加強日常檢查與維護。

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.
