Temperature measurement wire clamp for metering connection

Abstract

The invention discloses a temperature measurement wire clamp for metering connection. The temperature measurement wire clamp comprises a wire clamp body, a fastening bolt and an expansion sensor component, wherein a wire clamp groove is formed in the wire clamp body, a first swing block and a second swing block are arranged in the wire clamp groove, and the fulcrum end of the first swing block and the fulcrum end of the second swing block are matched with the two sides of the wire clamp groove respectively; the section of the swing end of the second swing block is in a round head shape, and the swing end of the first swing block is provided with an arc-shaped groove matched with the swing end of the second swing block; a vertical threaded hole is formed in the bottom of the wire clamp groove, the fastening bolt is provided with a flat gasket, the threaded end of the fastening bolt penetrates through the first swing block and the second swing block and then is matched with the vertical threaded hole in a threaded mode, and the bottom face of the flat gasket abuts against and is matched with the upper end face of the first swing block; and a wire penetrating hole is formed in the side face of the wire clamp body, and a wire can be clamped between the first swing block and the bottom face of the wire clamp groove after entering from the wire penetrating hole. Thus, the size and the safety of the wire contact surface are ensured, and the reliability is high.

Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to a temperature-measuring wire clamp for metering connection. Background technique [0002] As the direction of the development and construction of the power system, the smart grid requires the monitoring of the operating status of the transmission line in order to detect and eliminate line faults in time. As an important part of the distribution network, the 10kV line has many branches and covers a wide area. The joints of the lines in the power grid require a large number of connection clamps for distribution network construction. For the place where wire clips are installed in the line, if some key lines can be monitored and warned in real time, the safety and applicability of the wire clip can be greatly improved. At present, there are many wire clips used on the entire line, and the locations are scattered. When the employees of the power supply company go to the...

Problems solved by technology

Existing fittings simply consider connection, but do not consider expansion, resulting in complex installation, poor scalability, and inaccurate measurement when expanding sensors in the future.
