Description

A kind of penetrating cable clamp

Technical field

The utility model relates to a kind of instrument to the overhead distribution overhaul of the equipments, especially relates to a kind of penetrating cable clamp that does not have a power failure overhead distribution equipment is overhauled.

Background technology

Along with improving constantly of development and national economy and people's living standard, society is also more and more higher to the requirement of power supply reliability, the 10kV distribution system is mainly used in the conveying of enterprises and institutions and town dweller's electricity consumption, wide coverage, so the power failure operation of distribution system all can directly influence the reliability of power supply.In the 10kV distribution system, equipment such as a large amount of pole-mounted circuit breakers, disconnecting link, fuse switch, lightning arrester are equipped with, and cross in the kind in the operation of overhead distribution equipment, the wire jumper flat-plate heating of overhead transmission line, fuse switch and plug-in strip lead-in wire pile crown break, deviate from etc. all is common faults, and also need in the distribution system suspended insulated guide wire distribution transforming stand high-voltage connection is overlapped with newly-built, and the operations such as zero load overlap joint of the transformation insulated conductor being propped up wiring.Therefore when distribution line broke down or the equipment of distribution line transformed, a kind of method was by having a power failure overhead distribution equipment to be overhauled and transforms, but the processing that has a power failure not only can enlarge the power failure scope, and the activity duration is longer.For shortening interruption duration, with instruments such as penetrating cable clamps circuit is overhauled and transforms at present, as the disclosed penetrating cable clamp of CN2938501Y, comprise wire clamp main body and the pressure tooth that is connected on the wire clamp main body, described wire clamp main body is the frame that a side is provided with opening, on the wire clamp main body securing member is housed, the screw rod that the bottom has latch closure is screwed on the bottom girder of wire clamp main body, fixedly connected with briquetting in screw rod top, the lower pressing tooth of band wedge angle is equipped with on the top of briquetting, the upper pressing tooth of band wedge angle is housed on the back timber of wire clamp main body, and upper pressing tooth is corresponding with lower pressing tooth, during use, on, lower pressing tooth is harmonious, and two wire clamp that have insulating barrier are pressed in the tooth two, wears out the insulating barrier of lead by pressing tooth, after the energising, briquetting makes line conduction, and reduces the time that has a power failure, and handles the power supply reliability that still influences equipment to a certain extent but have a power failure, but structure is relatively complicated, the cost of manufacture height.Another kind method is by live line working overhead distribution equipment to be overhauled, but live line working is subjected to the restriction of transportation condition, meteorological condition, device structure, lighting requirement, has certain limitation, especially the insulated conductor place of widely applying, because the live line working overhead vehicle can not arrive the height of equipment, and often adopt earth potential indirect operating method, but be subjected to wire insulation to peel off the restriction of means and can't implement.

Summary of the invention

The purpose of this utility model just is to overcome above-mentioned deficiency a kind of penetrating cable clamp simple in structure, easy to use is provided.

The technical solution of the utility model is:

A kind of penetrating cable clamp, it comprises the wire clamp main body and is fixed on silver-plated alloy contact chip on the wire clamp main body, described wire clamp main body is hinged by the reach the standard grade clamp and the clamp that rolls off the production line, silver-plated alloy contact chip down is housed in the bottom of the clamp of reaching the standard grade, silver-plated alloy contact chip is housed on the top of the clamp that rolls off the production line, and upward silver-plated alloy contact chip and following silver-plated alloy contact chip are corresponding, the following handle of wire clamp main body is fixed on the upper end of action bars, stay cord is established in the end of up knob, stay cord can be in action bars or outside the action bars pulling up and down, at up knob with reach the standard grade back-moving spring is installed between the clamp.

Above-mentioned penetrating cable clamp is provided with the stay cord locating ring in action bars or outside the action bars, stay cord passes outside the lower end that locating ring hangs down to action bars.

The utility model adopts the advantage after the technique scheme to be: l, simple in structure.Penetrating cable clamp of the present utility model is by the wire clamp main body, be arranged on the following silver-plated alloy contact chip on the clamp of reaching the standard grade, be arranged on silver-plated alloy contact chip formation on the clamp that rolls off the production line, and on, following silver-plated alloy contact chip correspondence, the following handle of wire clamp main body is fixed on the upper end of action bars, stay cord is established in the end of up knob, stay cord can move up and down in action bars or outside the action bars, establish securing member on the wire clamp main body, at up knob with reach the standard grade back-moving spring is installed between the clamp, by the pulling stay cord, can drive the clamp that rolls off the production line moves up and down, and that the clamp of reaching the standard grade is fixed on the action bars is motionless, thereby make, silver-plated alloy contact chip punctures the insulating barrier and the bridle wire conducting that is fixed on the wire clamp main body of lead down, overhead distribution equipment is carried out operation, simple in structure, compact.2, easy to operate.The utility model is owing to be fixed on an eradication edge jumper on the wire clamp main body earlier, by insulating bar penetrating cable clamp is enclosed within on the aerial cable again, make the lead conducting that is connected on the penetrating cable clamp by the wire clamp main body, connect and finish the cross-over connection of insulated conductor and prop up, easy to operate.3, can realize live line working.The utility model is connected on the wire clamp main body because of thoroughly doing away with the edge jumper with one earlier, under the prerequisite of uninterrupted operation, by insulating bar operation penetrating cable clamp, with controller switching equipment places such as penetrating cable clamp cross-over connection wire jumper flat board, drop out fuse or disconnecting links, the conducting of fast quick-recovery circuit, improved operating efficiency and distribution line power supply reliability greatly, solved the height that the live line working overhead vehicle can not arrive at equipment, make the 10kV insulated conductor can not charged cross-over connection, technological difficulties such as connect.Penetrating cable clamp of the present utility model can be used for the overlap joint, newly-built of 10kV suspended insulated guide wire distribution transforming stand high-voltage connection, chargedly tears, builds line open, charged repairing lead, and prop up the live line working such as zero load overlap joint etc. of wiring to transforming insulated conductor.
