Description
Technical field
The present invention relates to a kind of proving installation, particularly relate to a kind of conductor resistance proving installation.
Background technology
From extra high voltage network to various micromotors, electric wire is indispensable in national economy and productive life.And it is various in style, have a large capacity and a wide range, user relates to each system of all trades and professions.The quality of electric wire is uneven, to the accurate test of its performance, can get rid of failure, avoids and reduces the accident in follow-up use.The test of electric wire and cable conductor direct current resistance is the Main Means that detects conductor electric conductivity, and the accuracy of electric wire and cable conductor resistance test is affected the evaluation of its performance and its follow-up use.For four-terminal measurement fixture, the potential electrode of every one end and galvanic electrode chuck spacing should be not less than 1.5 times of tested sample section girth.Now, the domestic bridge gripper providing is mostly potential electrode chuck and galvanic electrode chuck and insulating material and is connected as a single entity, and base all fixes, and cannot move the distance that regulates between the two to meet the needs of different cross section sample measurement.1.5 times of the pair cross-section girth sample within potential electrode and galvanic electrode spacing range, in this, grip device can be realized Measurement accuracy, but surpass two electrode separations for 1.5 times of sample perimeter of section, there is measuring error, can not determine its stability and accuracy, reference data is accurately provided can not to the test of follow-up performance.
