Problems solved by technology
At present, although there are many kinds of conductor connection fittings on the domestic market, among which U-shaped clamps, T-shaped clamps and wedge-shaped clamps can ensure reliable connection and repeated use of conductors, but due to the relatively small contact area between fittings and conductors If the contact resistance is small, the contact resistance will be large, and the temperature of the conductor connection will rise rapidly during the test. Especially when the test current is large, the connection between the fittings and the conductor will be deformed or burned due to high temperature, which cannot meet the test requirements; Connecting fittings such as copper tubes or aluminum tubes can meet the requirements of reliable connection of conductors and small contact resistance, but after crimping, copper tubes or aluminum tubes cannot be reused due to deformation, resulting in waste

Embodiment Construction
[0034] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0035] In this embodiment, the conductor connection clip is taken as an example, such as figure 1 As shown, the conductor connection clamp provided by the embodiment of the present invention includes: an outer clamp 1, an inner clamp 2, a fastener 3, and a conductor 4; When measuring DC or AC resistance, the conductor to be tested is connected to the lead conductor, and its electrical and mechanical properties are maintained. The outer clamp 1 is composed of two parts with symmetrical inwardly concave semicircular arcs in the middle and through holes at both ends. snapped together, such as Figure 2 to Figure 3 shown. The inner clip 2 is ring-shaped and is fastened by a semi-circular ring, and is installed in a circular hole formed by a semicircular arc. The conductor 4 is installed in the inner ring of the inner clip ...

The invention provides a conductor connecting clamp. The conductor connecting clamp comprises an outer clamp, inner clamps and fasteners, components are buckled to each other to form the outer clamp, the middle of each component is provided with symmetrical and concave semicircles, the two ends of each component are provided with through holes, and the fasteners are arranged in the through holes. The conductor connecting clamp is characterized in that the inner clamps are circular and formed by buckling semi-circular rings, and the inner clamps are arranged in round holes composed of the semicircles. Compared with the prior art, the conductor connecting clamp and an installation method thereof have the advantages that the structure is novel, installation is convenient, connection is reliable, contact resistance of the conductor connecting clamp and conductors is low, and the conductor connecting clamp can be used repeatedly.
Description
technical field [0001] The invention relates to a connecting wire clip, in particular to a conductor connecting wire clip used for temperature rise test and direct current or alternating current resistance measurement of an overhead wire or cable conductor in a power transmission line and an installation method thereof. Background technique [0002] In recent years, with the continuous acceleration of China's electric power development, China's power grid has also developed rapidly, the operating voltage level of the power grid system has continued to increase, and the network scale has also continued to expand. At present, power grid construction has become the main direction of my country's electric power construction. By 2020, a strong smart grid will be fully built, and the goal of building a world-class power grid will be initially realized. [0003] When performing temperature rise test, DC or AC resistance measurement on overhead wires or cable conductors, it is neces...
