Abstract

The invention relates to the technical field of resistance testing equipment, and further discloses an insulation and grounding resistance testing instrument. The instrument comprises a box body. A box cover is hinged to the middle of the top end of the box body. A rectangular groove is formed in one side of the front surface of the box body. The middles of the two sides of an inner cavity of therectangular groove are movably sleeved with rolling shafts. The rolling shafts are fixedly sleeved with wire wheels, a square groove is formed in the middle of the side, close to the wire wheels, of the box body, the middles of the rolling shafts are fixedly sleeved with round rods, and one ends of the round rods penetrate through and extend out of the square groove and are movably sleeved with square rods. According to the insulation and grounding resistance testing instrument, through cooperative use of an annular spring, a square rod, a square groove, a clamping groove, a round rod and a rolling shaft, when the square rod is pressed and one end of the round rod is separated from the clamping groove, the round rod can drive a wire wheel to rotate through the rolling shaft and wind a wirefor measurement, and therefore the purpose that the insulation and grounding resistance testing instrument can wind, arrange and measure the wire conveniently is achieved.

Description

technical field [0001] The invention relates to the technical field of resistance testing equipment, in particular to an insulation and grounding resistance testing instrument. Background technique [0002] The resistance tester is a new type of digital grounding resistance that abandons the traditional manual power generation method, adopts advanced large-scale integrated circuits, and uses DC / AC conversion technology to combine the three-terminal button and four-terminal button measurement methods into one model. The tester is suitable for measuring the grounding resistance of various devices and measuring the resistance value of low-resistance conductors in departments such as electric power, post and telecommunications, railways, communications and mines. [0003] The resistance tester is a kind of measuring device for measuring the grounding resistance of various devices. When in use, it is necessary to use a measuring wire to connect the measuring meter and the tester....
