Embodiment 1

[0025] Example 1, such as figure 1 As shown, the present invention provides a quick retractable device for grounding resistance tester wires. The whole device is arranged in a container 1. 6 and the box cover 7, the tailgate 5 and the box cover 7 are hingedly connected together, inside the container 1, a first wire storage room 8 and a storage compartment 9 are sequentially arranged from one end of the left side panel 2 to one end of the right side panel 3 , the instrument room 10 and the second wire storage room 11, which are separated by partitions 16 with the same structure, and at the same position of each partition 16, that is, one end near the tailgate 5 is provided with structures of different sizes. The same groove 17 is used as the storage location for the ground electrode 24. The inventor’s design avoids separately opening up the storage location for the ground electrode 24, which saves space. At the same time, the design of the groove 17 prevents the ground electrod...

Abstract

The invention belongs to the field of earth resistance testers, and particularly relates to a conduction wire rapid reeling and unreeling device for an earth resistance tester and a use method thereof. The conduction wire rapid reeling and unreeling device comprises a container; a first wire storage chamber, an object storage grid, an instrument chamber and a second wire storage chamber which areseparated through clapboards are arranged in the container; a current electrode wire reeling disc is arranged in the first wire storage chamber; reeling disc rocking handle and other auxiliary tools are arranged in the object storage grid; a resistance measuring meter is arranged in the instrument chamber; a voltage electrode wire reeling disc is arranged in the second wire storage chamber; an end, which is close to a rear baffle plate, of each clapboard is provided with a groove; and a grounding electrode is arranged in each groove. The conduction wire rapid reeling and unreeling device is simple in structure and reasonable in design; the phenomenon that a current electrode wire and a voltage electrode wire are tangled with each other, and time and labor are wasted for detaching and stroking is eradicated, so that measuring precision is improved; and meanwhile, meters are prevented from being damaged because of water soaking in windy and rainy days.

Description

technical field [0001] The invention belongs to the field of resistance testers, and in particular relates to a device for quickly retracting and releasing a wire of a grounding resistance tester and a method for using it. Background technique [0002] According to the "Transformer Operation Regulations": for transformers with a total capacity of 100 kVA and above, the grounding resistance of the grounding device should not exceed 4 ohms; for transformers with a total capacity of 100 kVA and below, the grounding resistance of the grounding device should not exceed Greater than 10 ohms; measuring the grounding resistance is an important item in the inspection and acceptance work before the transformer installation is completed and put into operation. [0003] The existing grounding resistance tester has two test wires, which are respectively a 20-meter voltage wire and a 40-meter current wire. In the actual test process, the two wires must be connected at the same time befor...
