Background

The grounding resistance is an important parameter for measuring whether the grounding state is good or not, the grounding resistance is a resistance encountered by current flowing into the ground through equipment and then flowing to another grounding body through the ground or diffusing to a remote place, and the good degree of contact between an electrical device and the ground is reflected by the grounding resistance. At present, a grounding resistance meter or a universal meter is often adopted to directly measure the grounding resistance of the equipment to judge whether the equipment is reliably grounded.

The ground resistance is one of the important safety indexes of 0I type and I type household appliances, and the intelligent closestool belongs to the I type household appliances. Although GB4706.1-2005 and GB4289-2005 have clear rules on how to accurately measure the grounding resistance, different test methods bring different test errors. The safety standards for household appliances stipulate that the ground resistance should include the sum of the resistances from the ground stud or ground electrode to each of the easily accessible non-live metal parts. The contact resistance measurement principle is that ohm's law R is U/I, a constant current source 25A is adopted, an alternating current voltmeter is used for measuring the voltage difference between two ends of a resistor, and then ohm's law is used for calculation. The ground resistance test of the intelligent toilet lid generally involves the following resistance values: ra is the sum of the material resistance of each easily accessible non-charged metal part and the contact resistance between them; rb is the contact resistance between the grounding wire post and a metal part which is easy to be touched by non-electrification; rc is contact resistance between the power line and the grounding wire column; rd is power line material resistance; measuring the contact resistance between the probe and the grounding electrode; rf, contact resistance between power line and ground electrode; and Rg, measuring the contact resistance between the probe and an easily-accessible non-charged metal part.
