用途和结构特殊的矿用电缆 Purpose and structure of special mine cable 1.低电感电缆 1. Low inductance cables 有强电与弱电之分,这里介绍一种强电用低感电缆。此电缆带有热耗散装置,用于各类接触焊机、电弧焊机与气动焊钳间相连接的新型水冷式低感电缆,具有结构简单合理、冷却水流通量大、不会形成堵塞阻断和限流现象、散热效果好、使用寿命长等特点。 With heavy current and weak current, here introduces a kind of high voltage with low sense of cables. The cable with a heat dissipation device, used for all kinds of resistance welder, arc welder and pneumatic electrode holder connected between the new type of low water cooled cable, has simple and reasonable structure, large cooling water circulation, will not become blocked block and the limit of flow phenomenon, good heat dissipation effect, long service life, etc. 这种新型低感电缆也包括电缆和电缆端头上固装着的接头,且电缆也是由正极缆芯和负极缆芯同装于外胶管中构成。由于这类低感电缆一般都是用于电压为25-50V、电流在7000-12000A之间的场合,冷却水在电缆中的短路导电现象基本上可忽略不计,所以在此低感电缆中没有使用隔离正极缆芯和负极缆芯的橡胶软管,只是特别设置了一条横断面呈轮辐状(俗称“梅花芯”状)的芯架,其“轮心”和相邻“辐条”间所围成的空间在顺轴线方向上即形成纵向沟槽,芯架上的纵向沟槽与电缆所配置的正极缆芯的总根数相同,其电缆部分就是以正极缆芯和负极缆芯分别搁于芯架的纵向沟槽内装置在外胶管中构成。正极缆芯和负极缆芯的两端头部分别同极集合成束夹固于缆芯夹中,然后固装在接头上,电缆的外胶管的端头部套装在接头的尾端部,并用套装在外胶管外的收紧箍紧密封 This new type of low sense of cable also include cable and cable end solid loading on the joint, and it is by the positive and negative cable core line cable core is packed with to the hose. Because this kind of sense of low cable is generally used in voltage of 25 to 50 v, current situation, between 7000-12000 - a short circuit conductive in the cooling water in the cable almost negligible, so in this sense of low cable didn't use the isolation of the positive and negative cable conductor cable core rubber hose, just set up a special cross-sectional spokes shaped (commonly known as the "plum blossom core") core frame, the heart of round and round into the space between adjacent "spokes" in longitudinal groove is formed along the axis direction, core frame longitudinal grooves and the positive cable conductor of the cable configured at the same total number of root, the cable is in the positive and negative cable conductor cable core put aside in the core of the longitudinal grooves device respectively among the hose. The positive and negative ends of the cable core cable core head respectively with a collection into a bundle of clip is the core in the clip, and then fixed on the connector, cable outer hose end head suits at the end of the joint, and set out hose outside tightening banding seal
