Abstract

The utility model relates to a three-groove parallel-groove wire clip for power line connection. The grooves are parallel to the wire clamp, and two or more pressure plates with a three-groove structure on the front view of the wire clamp body are connected to the wire clamp body through respective bolts and nuts. Advantages: First, it not only greatly reduces the number of parallel trench clamps and line connection points at the T-junction of each phase, but also reduces the line loss caused by heat generation and improves the power transmission capacity; second, it effectively shortens the The operating time and labor intensity of the operator are reduced, and the production efficiency is improved.

Description

Three groove parallel groove clamp

technical field

The utility model relates to a three-groove parallel-groove clamp for connecting electric power lines, which belongs to the field of parallel-groove clamp manufacture.

Background technique

Authorized announcement number CN2582236Y, name "power line parallel groove clamp", the upper splint and the lower splint are fastened together, and the fastening surface has two parallel and opposite concave grooves, which are penetrated from the middle by bolts, nuts and washers For fastening, there is a middle groove in the middle part of the fastening surface of the lower splint parallel to the two concave wire grooves, and the middle groove is set throughout the length. There are two steps lower than the top surface on both sides of the upper bolt groove on the non-fastening surface of the upper splint, and the edges on both sides of the upper splint and the lower splint are arc-shaped. There are longitudinal or transverse anti-slip embossments on the inner surface of the above-mentioned concave wire groove. Its shortcomings: First, a large number of parallel ditch clamps are used at the T-junction of the tower jumper, and the parallel ditch clamps are clamped at one connection. It takes 3 pieces to meet the electrical performance requirements. When three jumpers need to be connected together At least 6 parallel groove clamps are needed, not only the amount of parallel groove clamps is large, which is uneconomical, but also the use of parallel groove clamps, the combination gap between the parts is prone to corrosion, and long-term load operation is easy to cause line failure Second, when installing, it is not only labor-intensive and time-consuming, but also unsafe, and it is impossible to ensure that the torque of each bolt meets the design requirements.

Contents of the invention

Design purpose: To avoid the deficiencies in the background technology, to design a three-slot parallel-groove clamp that can effectively reduce the number of parallel-groove clamps used and ensure reliable connection of power lines.

Design scheme: In order to achieve the above design purpose. The clamp body has a three-slot structure in front view, and the design of two or more pressure plates with a three-slot structure in front view and the clamp body to form a three-slot parallel groove clamp is the main technical feature of the utility model. The purpose of this is: the three-slot parallel-groove clamp can reduce the number of parallel-groove clamps used at the T-junction of the jumper wire of the strain tower, so that only three T-junctions of each phase need to be installed, reducing the connection points of the line, and at the same time The working time of the operator on the pole is shortened, and the working efficiency is improved.

Technical solution: Three-groove parallel-groove wire clamp, the main body of the wire clamp has a three-groove structure in front view, and 2 or more pressure plates with a three-groove structure in front view are buckled with the wire clamp body to form a three-groove parallel groove wire clamp and on the wire Two or more pressure plates with a three-slot structure in front view on the clamp body are connected to the clamp body through respective bolts and nuts.

Compared with the background technology, the utility model not only greatly reduces the number of parallel ditch line clamps and line connection points at the T-junction of each phase, but also reduces the line loss caused by heat generation, and improves the transmission efficiency. The second is to effectively shorten the operating time and labor intensity of operators and improve production efficiency.
