Embodiment

[0028] like figure 1 As shown, the box is made of stainless steel; length 0.4M; width 0.2M; height 0.18M; total weight 2.4kg. A box cover 2 is provided above the box body 1, and an elastic fixing band 3 is provided on the inner surface of the box cover, and tools can be fixed on the box cover by the fixing band. One end of the box body 1 is provided with a voltage wire winding shaft and a current wire winding shaft respectively. The voltage lead wire 4 and the current lead wire 5 are respectively wound on two independent winding shafts. Free and flexible, time-saving and labor-saving requirements; the other end of the box is provided with a grounding resistance meter 6, and the grounding resistance meter is firmly connected with one end of the voltage lead and current lead, and the other end of the voltage lead and current lead leads out of the box; There is a space between the body wall and the resistance meter to form an accessory compartment 7, and the grounding grid lead ...

Abstract

The invention relates to an integration ground resistance measuring device. The integration ground resistance measuring device is structurally characterized in that a voltage line roll and a current line roll are respectively arranged at one end of a box body, and a voltage lead and a current lead are arranged on two independent rolls in a wound mode respectively; a ground resistance megger is arranged at the other end of the box body and firmly connected with one ends of the voltage lead and the current lead, and the other ends of the voltage lead and the current lead are led out of the box body; an interval is formed between the inner wall of the box body and the ground resistance megger to form an accessory cabin; crank inserting holes which correspond to the voltage line roll, the current line roll and the ground resistance megger are formed in the lateral wall of the box body. By means of the integration ground resistance measuring device, time and labor are saved, test data are accurate, attention is paid to actual effects, carrying is easily carried out, connection is conveniently carried out, winding and unwinding are free and flexible, and manpower and material resources are saved; meanwhile, the integration ground resistance measuring device has the advantages of shake prevention, dust prevention, water prevention, heat preservation and the like. The integration ground resistance measuring device is small in occupied area in site and easy to monitor, and guarantees are brought to safety production.

Description

technical field [0001] The invention relates to a power equipment measuring box, in particular to an integrated grounding resistance measuring device. Background technique [0002] In the prior art, there are mainly problems in the following aspects during on-site testing such as grounding resistance. [0003] 1. The retraction and release of current leads and voltage leads. [0004] 1.1 When independent current lead wires and voltage lead wires are used, the current lead wires and voltage lead wires are easily confused when receiving and discharging each time. [0005] 1.2 When the current and voltage lead wires use the same pay-off shaft, the current lead wires and voltage lead wires intersect together will cause measurement errors; it is also difficult to use the angle method to measure the grounding resistance, which is limited by geographical conditions. [0006] 1.3 The current leads and voltage leads use their own independent pay-off shafts, and the increase in tes...
