Multi-line resistance test system based on power distribution control

Abstract

The invention discloses a multi-line resistance test system based on power distribution control, the system comprises an outer cabinet body and an inner cabinet body, the top end of the outer cabinet body is fixedly provided with a plurality of first prompt lamps, the top end of the outer cabinet body is fixedly provided with a plurality of second prompt lamps, and the center of the top end of the outer cabinet body is fixedly provided with a storage battery. The storage battery is a lithium battery, a fixing mechanism is arranged at the top end of the inner cabinet body, a plurality of resistance measuring instruments are arranged on the fixing mechanism in a clamped mode, and a door plate is movably installed at the front end of the inner cabinet body through a hinge. A resistance measuring instrument detection end connecting wire bypasses a roller and penetrates into an extension rod, when the extension rod moves downwards, the resistance measuring instrument detection end connecting wire is stretched, so that the connecting wire extrudes the roller and further extrudes a fourth spring, and when the extension rod resets, the fourth spring resets, so that the resistance measuring instrument detection end connecting wire is tightened, and the resistance measuring instrument detection end connecting wire is tightened. And the connecting line is prevented from being pulled and broken due to winding of the overlong connecting line during up-down movement.

Description

technical field [0001] The invention relates to the field of resistance testing, in particular to a multi-line resistance testing system based on power distribution control. Background technique [0002] Electric current in metallic conductors is formed by the directional movement of free electrons. Free electrons frequently collide with metal positive ions in motion, and this collision hinders the directional movement of free electrons. The physical quantity that expresses this obstacle is called resistance. Not only metal conductors have resistance, but other objects also have resistance. The resistance of a conductor is determined by its own physical conditions, and the resistance of a metal conductor is determined by its material properties, length, thickness (cross-sectional area), and use temperature. Resistance is a physical quantity that describes the conductivity of a conductor. It is represented by R. The unit of resistance is ohms, abbreviated as ohms, and the s...

Problems solved by technology

[0003] The existing power distribution control box needs to periodically test the line resistance to determine the normal operation of the line. When there is a short circuit inside the line, the line resistance becomes smaller. When the line connector is loose, the resistance at this time Increasing the height will reduce the safety of the line when it is used, but it is necessary to disconnect the detection line during line detection, and then connect the detection meter in series inside the line for measurement to prevent the internal voltage of the line from affecting the test results, and disconnect the line to ensure accuracy However, it will make the test line unusable and affect the power distribution control process. At the same time, it is necessary to manually record the test data during the test, and then compare the data with the normal data to get the result. When working for a long time, manual record comparison is very easy to appear Deviations lead to wrong conclusions and affect subsequent maintenance work, so a system is urgently needed to solve the above problems
