Abstract
The invention discloses a power station equipment cable insulation puncture wire clamp and a wire clamping method. A traditional pre-branch cable, compared with a bus groove, is relatively high in price, needs a specific equipment for hoisting and is time-consuming and labor-consuming although having the characteristics of a light weight, a small outer diameter, good water repellency, good corrosion resistance, good shock resistance and a low requirement on the environment; and as measurement for the practical size of a building electric vertical shaft is required before booking and then a factory produces based on the practical size, each produced cable clamp has immutability. The power station equipment cable insulation puncture wire clamp comprises an upper insulating shell (1), a lower insulating shell (1) and a branch wire protective cap (9); the upper insulating shell and the lower insulating shell are connected; and the upper insulating shell and the lower insulating shell are respectively connected with the branch wire protective cap. The power station equipment cable insulation puncture wire clamp is applied to power station equipment.
Description
Technical field:
The present invention relates to a kind of power station equipment cable insulation penetrating cable clamp and clamp method.
Background technology:
Cable clip has another name called cable fixed mount, cable clip is made up of clamp, spring, bearing pin and switch pin etc., the H type of clamp inner side up and down respectively has a gathering sill, 4 corresponding up and down square holes are had at the two ends of gathering sill, the side of clamp is two parallel gusset pieces, opposite side has a gusset piece, and the circular hole having same apertures on each gusset piece is to adopt Spring Card lock fixed form to realize.Traditional pre-branched cable compares with bus duct, although having lightweight, external diameter is little, water proofing property, corrosion resistance, shock resistance is good, the feature that environmental requirement is low, but price is higher, it is necessary to special equipment hoisting, time-consuming take a lot of work, and, needing the actual size to architectural electricity vertical shaft to measure before order, factory is making according to actual size, and the cable clip produced has immutable more property.
Summary of the invention:
It is an object of the invention to provide a kind of power station equipment cable insulation penetrating cable clamp and clamp method.
Above-mentioned purpose is realized by following technical scheme:
A kind of power station equipment cable insulation penetrating cable clamp; its composition includes: upper insulation shell, lower insulation shell, branch line protective cap; described upper insulation shell is connected with described lower insulation shell, and described upper insulation shell is connected respectively at described branch line protective cap with described lower insulation shell.
Described power station equipment cable insulation penetrating cable clamp, described upper insulation shell is connected with clamp nut, and described clamp nut is connected with torque nut.
Described power station equipment cable insulation penetrating cable clamp, described lower insulation shell is provided with power-assisted nut, bolt insulation sleeve.
Described power station equipment cable insulation penetrating cable clamp, described upper insulation shell and described lower insulation shell are connected to O-ring seal, and described O-ring seal is connected with piercing blade.
nullUtilize the method that described power station equipment cable insulation penetrating cable clamp carries out clamp，When the method comprises the steps: that regarding cable branch connects，Peel off cable outer layer sheath，After branch cable being inserted the branch line cap with water-proof function and determining main line branch location，The force moment screw on wire clamp is tightened with box spanner，In the process of stubborn torque nut，The upper and lower two pieces of insulators hiding high-conductive metal piercing blade of wire clamp close up gradually，Meanwhile，The arc O-ring seal being wrapped in around piercing blade is progressively close to cable insulation，Piercing blade dynamics is more big，When the seal degree of O-ring seal and the contact of piercing blade metallic conductor reach optimum efficiency，Torque nut will Automatic-falling，Now，Main line is connected with branch，And water resistance and electrical effects are best，It is greatly improved the operation stability of electrical network.
Beneficial effects of the present invention:
1. the present invention does not need to use termination rack, coupling box.And joint warp resistance, shockproof, waterproof, anticorrosion are aging, use insulation puncture line clamping to do cable branch, and comprehensive benefit is obvious, and cost performance is better than conventional conventional coupling arrangement, can do branch in cable optional position.Simple installation is reliable, only need to use box spanner, can charged install, and electric property is excellent, integrated cost lower than conventional coupling arrangement, safe and stable operation in each circuit.
The waterproof sealing performance that the present invention is very good because insulation puncture line clamping has, therefore, can be used for continuing and branch of submerged cable.This brings great convenience to the construction of submerged cable, operation and maintenance, and torque nut punctures constant pressure, it is ensured that good electrical connection and non-damage wires.
Self sealing structure of the present invention, moistureproof, waterproof, anticorrosion, extend the service life of insulated conductor and wire clamp,
Adopt specialty contact blade, it is suitable for copper (aluminum) docking and copper-aluminium transition, electrical contact resistance is little, and contact resistance, less than 1.1 times of isometric offset resistance, meets DL/T765.1-2001 standard, special insulation housing, anti-light photograph and environmental aging, dielectric strength > 12KV, cambered surface designs, it is suitable for and connects with (different) footpath wire, join domain wide (0.75mm2-400mm2).
Simple installation of the present invention: not needing the insulated hull peelling off cable can do cable branch, joint is completely insulated, does not need to block leader cable；Use safety: joint warp resistance, shockproof, waterproof, fire-retardant, anti-couple-corrosion is aging, it is not necessary to safeguard；Save cost: installing space is minimum, save crane span structure and civil engineering costs.Building is applied, it is not necessary to termination rack, distribution box；Do not need cable to return line, save cable investment.The expense of cable+penetrating cable clamp, lower than other electric power systems, is only about the 40% of plug-board bus bar, is about the 60% of prefabricated branch cable.
