Description
Technical Field
The utility model relates to a conductor mechanical properties testing machine for high tension switchgear.
Background
The metal hardness detection is the most rapid, economic and simple test method for evaluating the mechanical property of the metal. The main purpose of hardness testing is to determine the suitability of a material, and hardness testing is usually performed by taking a sample and testing it on a brinell hardness tester after appropriate processing. In a few occasions with low requirements, a simple portable Brinell hardness tester or a hammer Brinell hardness tester is used for testing, but the error of the instruments is too large, the error given in the technical index is +/-8%, the error in practical application is often more than 10%, and only a rough result can be given.

Detailed Description
As shown in figure 1, the mechanical property testing machine for the conductor for the high-voltage switch comprises a machine frame 4, wherein a bearing platform 1 is arranged at the bottom of the machine frame 4, a cooling cavity 9 is arranged in the bearing platform 1, and a temperature sensor 10 is arranged in the cooling cavity 9. And a mold 3 is arranged on the cooling cavity 9, and a conductor to be tested is placed on the mold 3. The bottom surface of the die 3 is provided with a pressure sensor 2, and the pressure sensor 2 passes through the cooling cavity 9 and is arranged in the bearing platform 1; a pressing plate 8 is arranged above the die 3, and the pressing plate 8 is connected with a piston rod 7 of the air cylinder 6; a PLC controller 5 is arranged on one side of the frame 4. The pressure sensor 2, the temperature sensor 10 and the air cylinder 6 are electrically connected with the PLC 5. The cylinder 6 drives the pressing plate 8 to extrude the conductor, and the Rockwell hardness value is obtained by measuring the depth of the indentation.
The pressure sensor 2 is a piezoresistive pressure sensor, is convenient to use and high in sensitivity, and can effectively detect the load of a conductor.
The cooling cavity 9 simulates the use state of the conductor at low temperature at night and at the subzero temperature in winter, and the hardness detection accuracy is improved.
