Abstract
The utility model relates to a cable belonging to basic electric components, particularly a high-voltage flat cable for a mine. The utility model is characterized in that the main core threads (1) of the cable are arranged in a figure-1 shape and form a flat shape, the outside of the main core threads (1) are coated and wound with a middle protective layer (2), and the cable sheath is a sectional bridge-shaped flat sheath parted by rubber rings (6) with expansion joints. The utility model has the advantages of good mechanical performance and good electrical performance. The structural strength is higher, the unit weight is lighter and the service life is longer than common rubber sheath flexible cables for a mine. The cable is laid and maintained simply and conveniently, and the automatic monitoring of cable operational accidents is implemented when the cable is matched with the special electric switch. The utility model is suitable for the use of the mobile safety power transmission to the excavation equipment for a mine.
Description
The utility model relates to the cable in the essential electronic element, is specially a kind of mine high pressure flat cable.
Domestic and international various extractive industry mine soft cables generally adopt Plastic-sheathed Cable at present.Because mine stope operating mode is abominable, cable cover(ing) breaks, and failure of insulation causes accident of power supplys such as phase fault or ground connection that generation is often arranged, and its main cause is that cable is inclined by rock often to fall and the impact of blasting flyrock, or rolled over by huge of ore deposit rock and mine car extruding to pound.This overwhelming majority that accounts for the mining cable rate of failure by the cable fault due to the mechanical external force.
The purpose of this utility model provides that a kind of to have shock resistance, anti-extruding, tension shearing resistance, mechanical performance and an electrical property good, lay and keep in repair easy, and can be supporting with special-purpose electric switch, realize the cable interruption of service mine high pressure flat cable of monitoring automatically.
Structure of the present utility model mainly contains four parts:
First, cable core: lead suede by the High-Voltage Insulation in three suitable line footpaths and be the in-line planar alignment, constitute the three-phase master core; Other has two common insulated conductors in little line footpath is monitoring cable.
Sheath during second portion, core insulation strengthen: adopt the wrapped cable master of high-intensity fiber impregnation strap phase-splitting heart yearn, form sheath in the core insulation enhancing, to improve ore deposit cable tension shear behavior.
Third part, the flat sheath of bridge shape: the flat ring assembled in series of bridge shape that is plugged with the I-shaped pad by some joint dresses forms the flat sheath of ore deposit cable bridge shape, and its bridge pier of the flat sheath of bridge shape is the I-shaped pad, and bridge opening is the space that holds cable master heart yearn, with carrying compression and impact load; There is an open groove upper surface of I-shaped pad to hold monitoring cable.
The 4th part, expansion joint: be assemblied in respectively by the flat ring-type cushion rubber of some joints and respectively save between the flat sheath of bridge shape, form ore deposit cable expansion joint.
The utility model is compared with existing rubber cover mining cable, the structural strength height, light unit weight, for ease of maintenaince, mechanical performance and electrical property all have good improvement, can obviously reduce the cable fault due to the mechanical external force, prolong the service life of mining cable, be fit to the transmission of electricity of mine excavation equipment moving type security and use.
Accompanying drawing 1 is the horizontal cut-away view of the utility model mine with the high pressure flat cable.
Accompanying drawing 2 is the external form vertical view of the utility model mine with the high pressure flat cable.
In the accompanying drawing: (1)-cable master heart yearn, (2)-middle sheath, (3)-I-shaped pad, (4)-monitoring cable, (5)-flat ring, (6)-expansion joint cushion rubber.
Cable master heart yearn of the present utility model (1) is selected chlorosulfonated polyethylene rubber, insulation 6KV, high pressure lead wire (JBYH) for use, or second third glue insulation neoprene sheath, high pressure lead wire (JFEM); Monitoring cable (4) is selected polyethylene insulation copper conductor (BY-1.5) for use.Every main heart yearn is by the vertical bag of continuous synthetic fibre dipped type cord fabric band one deck, wrapped again one deck, form sheath (2) in the thickness 1.5-3.5 millimeter core insulation enhancing, three-phase master heart yearn (1) word order, penetrate simultaneously by the special flat ring (5) of high-impact pressure nylon (modified Pa 6 6) with two monitoring cables (4), again two I-shaped pads (modified Pa 66 is made) that have open groove are clamp-oned flat ring (5), main heart yearn (1) and monitoring cable (4) are separated from each other separately, and located, form the equidistant flat formation of cable master's heart yearn (1), constitute the outer flat ore deposit of the joint cable that is covered with bridge shape sheath of line.So more piece ore deposit cable is separated through expansion joint cushion rubber (6), and assembled in series becomes every mine 250 meters long high pressure flat cable.Has grade 3-6KV, electric current 50A-200A product line.
Claims (2)
1, a kind of mine high pressure flat cable, comprise cable master heart yearn (1), insulating barrier, sheath, it is characterized in that cable master heart yearn (1) in-line planar alignment, be flat, sheath is made up of the flat ring (5) that some joint dresses are plugged with I-shaped pad (3), be the flat sheath of bridge type, and respectively save between the flat sheath and separate by cable expansion joint cushion rubber (6).
2, mine as claimed in claim 1 high pressure flat cable is characterized in that being provided with on the dress plug I-shaped pad (3) in flat ring (5) an open groove that holds monitoring cable (4).
