Abstract

The invention discloses a design method of a special winding and unwinding device for different proportional test lines of a grounding resistance tester. The design method comprises the following steps that 1, according to the test scene of the ground resistance tester, the length of the test line is determined, the speed ratio of a hand-operated rod to the take-up and pay-off end A to the take-upand pay-off end B is determined, and the diameter of the device is determined; 2, the number of teeth of each gear of an input epicyclic gear train is determined according to the transmission model of the epicyclic gear train input by the device; 3, the number of teeth of each gear train of a transition turnover wheel system is determined according to the transmission model of the transition turnover wheel system of the device; and 4, the modulus of an input turnover wheel system gear and the transition turnover wheel system is determined according to the diameter of the device. According tothe design method, a motion mathematical model is established according to the transmission principle of the device, the length ratio of the lines can be tested according to application occasions, a special take-up and pay-off device is designed according to the take-up and pay-off speed and the diameter of the device, and the accurate take-up of the test site is realized.

Description

technical field [0001] The invention relates to a design method of a special take-up and release device for a ground resistance tester, in particular to a design method for a special take-up and take-off device for different ratio test lines of a ground resistance tester. Background technique [0002] The ground resistance tester is a detection instrument for lightning protection facilities, which is closely related to the national economy and safety. During the detection of lightning protection facilities, it is necessary to retract and release the current electrode connecting wire and the voltage electrode connecting wire. In the case of a larger building with many test points, it is necessary to retract and release the current line connection line and the voltage connection line many times. Due to the large size of the lightning protection facilities, the different measuring points of the voltage electrode and the current electrode of the grounding resistance tester, and ...
