Description

Technical Field

[0001] The utility model relates to the technical field of equipotential testers, in particular to a novel protective device for equipotential testers. Background Art

[0002] "Lightning protection detection" is to test the effectiveness of lightning protection devices. Equipotential testers are also used for lightning protection detection. Equipotential testers are also called equipotential connection resistance testers. They are suitable for measuring the equipotential connection resistance between metal components in buildings and the resistance of the connecting conductors between various electrical equipment and the ground grid.

[0003] The prior art discloses an equipotential tester with a protective structure with an application number of 202122732663.0, including a protective box, a wire take-up groove is provided at one end of the protective box away from the main body of the tester, a movable plate is slidably installed inside the wire take-up groove, a side plate is fixedly installed on one side of the movable plate, a rotating shaft is sleeved inside the side plate, a wire take-up roller is sleeved outside the rotating shaft, a rotating disk is fixedly installed on the side of the rotating shaft close to the side plate, positioning grooves are provided at both ends of the top of the side plate, a lifting plate is sleeved inside the protective box close to one end of the side plate, positioning rods are fixedly installed at both ends of the bottom of the lifting plate, and reset springs are fixedly installed at both ends of the bottom of the lifting plate. By setting the movable plate, side plate, rotating shaft, wire take-up roller, positioning groove, lifting plate, positioning rod and reset spring, after the wire take-up roller is located outside the protective box, the effect of arranging the connecting wires is achieved, which solves the problem that it takes a lot of time to straighten the connecting wires when taking them out later. Although the above case can protect the equipotential tester, the existing technology is still inconvenient to carry and the heat dissipation effect is not ideal. The equipotential tester generates a lot of heat when working, and it is easy to accumulate too much heat by relying on the heat dissipation holes to dissipate heat naturally. For this reason, we propose a new type of equipotential tester protection device to solve the above problems. Utility Model Content
