Detailed Description
Example 1
The utility model provides a reposition of redundant personnel fastener for built on stilts distribution lines, its characterized in that: the distribution wire clamp for the overhead distribution line is of a parallelogram structure, is based on an aluminum base, and comprises a distribution wire clamp aluminum base 1, a middle parallel groove wire clamp 2, an auxiliary wire clamp I3, an auxiliary wire clamp II 4, a bolt I5, a bolt II 6, an M10 bolt 7, a quick buckle I8 and a quick buckle II 9;
wherein: 3 current paths are divided on the aluminum base 1 of the shunt wire clamp, a middle parallel groove clamp 2 is integrated in the middle of the aluminum base 1 of the shunt wire clamp, and an auxiliary wire clamp I3 and an auxiliary wire clamp II 4 are arranged on two sides of the aluminum base 1 of the shunt wire clamp; a quick buckle II 9 is arranged on the auxiliary wire clamp I3, and a quick buckle I8 is arranged on the auxiliary wire clamp II 4;
the first auxiliary wire clamp 3 is connected with the aluminum shunt wire clamp base 1 through a second bolt 6, and the second auxiliary wire clamp 4 is connected with the aluminum shunt wire clamp base 1 through a first bolt 5;
when the wire connection is involved in the engineering construction, bare wires on two sides are inserted oppositely, pass through the auxiliary wire clamp and are fixed up and down in the middle parallel groove wire clamp. After the fixing, the auxiliary wire clamps on the two sides are fixed.
The auxiliary wire clamp I3 and the auxiliary wire clamp II 4 are symmetrically arranged in a diagonal manner.
The middle parallel groove clamp 2 is an elastic double-channel split clamp structural part.
On reposition of redundant personnel fastener aluminium system base 1, 3 current path have been divided, integrated a set of parallel groove clamp in the middle of on this base simultaneously, designed two sets of auxiliary clamps at both sides. When the wire connection is involved in the engineering construction, bare wires on two sides are inserted oppositely, pass through the auxiliary wire clamp and are fixed up and down in the middle parallel groove wire clamp. After the fixing, the auxiliary wire clamps on the two sides are fixed.
When the shunt wire clamp is inserted, the wires on two sides are bare wires and have the conductive characteristic, so the following three current paths are generated:
after entering the shunt wire clamp, the current in the wire at one side flows through the auxiliary wire clamp, directly flows to the auxiliary wire clamp at the other side through the upper current path and further flows into the wire at the other side;
after entering the shunt wire clamp, the current in the wire at one side flows through the auxiliary wire clamp, directly flows to the auxiliary wire clamp at the other side through the lower current path, and then flows into the wire at the other side;
after entering the shunt clamp, the current in the wire at one side flows through the middle parallel groove clamp and then flows into the wire at the other side.
Example 2
The invention consists of the following parts: 1-an aluminum base of the shunt wire clamp; 2-middle parallel groove clamp; 34-an auxiliary wire clamp; 56-M8 bolt 2;7-M10 bolt 2; 89-snap as shown in figure 1. The base, the middle parallel groove clamp and the auxiliary clamps at two sides are made of aluminum and are formed by die sinking and pouring. The wire clamp is fixed by two types of bolts with the diameter of 8mm and 10 mm. The auxiliary wire clamp buckle side adopts the quick buckle of formula of hanging to see figure 3, and the buckle is also pour along with base and auxiliary wire clamp and is formed.
The whole length of the invention is 220mm, the width is 110mm; the wire clamp is in a parallelogram structure, the middle parallel groove clamp is designed according to JBL50-240/JBL10-70, and the length is 47mm, the width is 60 mm/the length is 40mm, and the width is 40mm, so that the wire clamp can be used for connecting wires of different types. The length of the auxiliary wire clamps on the two sides is 40mm, the width of the auxiliary wire clamps is 40mm, and the quick buckle and the bolt jointly play roles in auxiliary fixing and conducting current as shown in figure 2.
In specific application, see fig. 2 in detail, two red wires are different and need to be connected through a shunt wire clamp. When a current II = I1+ I2+ I3 flows from the left side to the right side through the LGJ wires, I1 flows from the left LGJ wire to the right LGJ wire through the middle parallel groove clamp, forming a current path; i2, the left LGJ wire flows through the right LGJ wire from the left auxiliary wire clamp along the upper current path of the parallelogram above the aluminum base to form a current path; i2 flows from the left LGJ wire to the right LGJ wire along the lower current path of the parallelogram below the aluminum base by the left auxiliary clamp to form a current path.
When the line load is suddenly increased or a ground fault occurs to generate short-time current impact, the wire clamp at the joint can cause the bolt to loosen after being heated. And then lead to contact failure, the resistance increases, has aggravated the possibility that the fastener contact department generates heat and burns out, causes the broken string trouble easily. After the shunt clamp is used, the double-side auxiliary clamps and the middle parallel groove clamp are mutually redundant, and the shunt clamp shunts passing loads respectively during normal operation, can still continuously operate under the load when a side clamp is burnt, and improves the reliability of power supply.
