Problems solved by technology

[0003] According to the provisions of Article 8.5 of the State Grid Unidirectional Smart Energy Meter Type Specification Q / CDW 1355-2003: when the voltage and current terminals are subjected to an axial pressure of 60N, the terminals should not be loosened or displaced. The existing thrust test is mainly It is done by manually loading and observing the deformation with the naked eye. There are also a small number of automatic pressure-applying machines, but it is difficult for automatic pressure-applying machines to observe pressure changes, and it is inconvenient to intuitively monitor real-time pressure changes during testing. Observed

Abstract

The invention discloses a push-pull force testing device for an intelligent electric energy meter, which comprises a base, a positioning piece for fixing the electric energy meter is arranged on the base, a detection box is movably arranged on the base, a pressure applying mechanism is arranged in the detection box, and a terminal of the electric energy meter is pressed through the pressure applying mechanism. The push-pull force testing device comprises a detection box, a pressure applying mechanism is arranged on the outer wall of the detection box, an amplifying mechanism is arranged in the detection box, the amplifying mechanism is in transmission connection with the pressure applying mechanism, an observation piece used for observing pressure change is arranged on the outer wall of the detection box, and the observation piece is in transmission connection with the amplifying mechanism. According to the electric energy meter terminal stress detection device, original tiny displacement during pressure application can be amplified, detection personnel can conveniently observe the pressure change condition, the stress condition of the electric energy meter terminal can be better reflected, the LED lamp is arranged, the pressure change condition can also be reflected through the brightness change of the LED lamp during pressure application, and the detection personnel can more accurately and rapidly detect the electric energy meter terminal.

Description

technical field [0001] The invention relates to the technical field of testing devices, in particular to a push-pull force testing device for smart electric energy meters. Background technique [0002] With the rise of smart grid construction in countries all over the world, smart energy meters, as the terminals of smart grids, have been widely promoted and applied in countries all over the world. The accuracy and reliability of smart energy meter measurements are still the focus of attention. It directly affects For the economic interests of power generation companies, power supply companies and power customers, thrust testing is a very important full-performance test item in the quality control of smart energy meters. [0003] According to Article 8.5 of the State Grid Unidirectional Smart Electric Energy Meter Type Specification Q / CDW 1355-2003: When the voltage and current terminals are subjected to an axial pressure of 60N, the terminals should not be loosened or displa...
