Background

The grounding resistance measuring instrument is a resistance measuring device, and is used for measuring the grounding resistance of various devices and the resistance value of a low-resistance conductor in departments of electric power, post and telecommunications, railways, communication, mines and the like; soil resistivity and ground voltage can also be measured. The grounding resistance measuring instrument abandons the traditional manual hand-operated power generation working mode, adopts an advanced medium-large scale integrated circuit, and combines a three-terminal button measuring mode and a four-terminal button measuring mode into a novel grounding resistance measuring instrument by applying a DC/AC conversion technology. The working principle is that the DC/AC converter in the machine changes the direct current into the low-frequency constant current of alternating current, the low-frequency constant current passes through the auxiliary grounding electrode C and the object to be measured E to form a loop, the alternating current voltage drop is generated on the object to be measured, the alternating current voltage drop is sent to the alternating current amplifier for amplification through the auxiliary grounding electrode P, and the alternating current voltage drop is sent to the meter head for display through the detection. With the aid of the magnification switch, three different limits can be obtained: 0-2 omega, 0-20 omega, 0-200 omega. The structure adopts high-strength aluminum alloy as a shell, and adopts a phase-locked loop synchronous tracking detection mode and a switched capacitor filter on a circuit to prevent power frequency and radio frequency interference, so that the instrument has better anti-interference capability; the DC/AC conversion technology is adopted to convert the direct current into the low-frequency constant current of the alternating current so as to facilitate the measurement; the auxiliary grounding resistance is allowed to change between 0-2 k omega (RC) and 0-40 k omega (RP), so that the measurement result is not influenced; the grounding resistance measuring instrument does not need manual balance adjustment, 3(1/2) bit LCD displays that besides the grounding resistance, the low resistance conductor resistance, the soil resistivity and the AC ground voltage can be measured; the ground resistance tester for the distribution transformer of the existing rural power grid 10kv station area is used in the process of using, and no corresponding supporting structure exists, so that the ground resistance tester can be directly placed on the ground for use, and the ground resistance tester can not be directly placed on the ground for use when water or mud exists on the ground, so that the test can be influenced finally.
