Description

Complete set of tower grounding resistance test tools

technical field

The utility model relates to a tool for testing a pole tower grounding network of a power transmission line in a power network, in particular to a complete set of pole tower grounding resistance testing tools.

Background technique

The tower grounding device is an important part of the transmission line, and its main function is lightning protection. Whether the grounding device meets the requirements, it is necessary to test the grounding grid to judge whether the grounding grid should be repaired.

At present, the grounding resistance test of the grounding network generally adopts the domestic ZC-8 ground resistance meter set, which includes a ZC-8 ground resistance meter, 2 test rods and 3 test lines (5m, 38m, 60m). Due to the messy tools and structural limitations, there are mainly the following defects: 1. The test line is long and directly looped together. When collecting/releasing the test line, it is usually collected/released manually. Only one test line can be received/released at a time. / Putting the test line is slow and prone to entanglement. Cleaning the test line is a very cumbersome task and takes a lot of time; 2. The test line is clamped on the test rod by a clip, and it is easy to fall off. The test rod and the test line exist Poor contact problem; 3. There is no protective measure on the top of the test rod, which is easy to be damaged; 4. The tools cannot be effectively unified and concentrated, and are easy to lose. This not only affects the speed of receiving/releasing the test line, but also seriously affects the work efficiency, resulting in unnecessary cost increase.

Contents of the invention

The purpose of the utility model is to provide a complete set of tower grounding resistance test tool, which prevents the phenomenon of chaotic winding when receiving/releasing the test line, and effectively improves the work efficiency.

The utility model is achieved in that:

A complete set of tower grounding resistance testing tools, including a ground resistance meter, a test line and a test rod, the test rod includes a ground electrode and a handle, and also includes a frame and a wire wheel, and the ground resistance meter and wires are arranged on the frame The reserved position of the wheel is provided with a bearing on the reserved position of the wire wheel, and the wire wheel is installed on the frame body through the bearing, and the test line is wound on the wire wheel.

The bearing is laterally supported in the center of the reserved position of the wire wheel by a bearing bracket connected to the frame body.

The bearing support is fixedly supported in the middle part of the bearing, and wire wheels are respectively installed on the bearings at both sides.

Pulleys are arranged at both ends of the anchor hole of the wire wheel.

A handle is provided on the outer side plate of the wire wheel.

The end of the test line is connected with an open terminal ring; the test rod is provided with a terminal head with a bolt structure.

The upper end of the test rod is provided with a head guard which is larger than the radial cross-sectional area of the test rod.

The complete set of tower grounding resistance testing tools also includes a box body.

The beneficial effects of the utility model are:

1. It eliminates the phenomenon of chaotic winding when receiving/releasing the test line, saves time and effort, and effectively improves work efficiency.

2. The wire wheels rotate independently, which meets the requirement of not necessarily synchronizing when receiving/releasing the test wire, and is easy and fast to operate.

3. Prevent shaking when the remote meter is used to affect the accuracy of the test.

4. It not only solves the problem of poor contact between the test rod and the test line, but also prevents the damage of the test rod.

5. Equipped with a box, all tools except the test rod are stored in the box, which solves the problem of tools being messy and easy to lose, and is easy to carry and move.

Detailed ways

Referring to Fig. 1 and Fig. 2: the utility model is also provided with frame body 1 and wire wheel 3 on the basis of existing ground resistance meter 2, test line 6 and test rod 8, and this existing test rod 8 comprises ground electrode and handle. On the frame body 1, there are reserved positions for the ground resistance meter 2 and the wire wheel 3, so that the ground resistance meter 2 is placed in the reserved position set on the frame body 1 to prevent the ground resistance meter 2 from shaking when the meter is remote affect the accuracy of the test. A bearing 4 is arranged on the reserved position of the wire wheel 3, and the bearing 4 is laterally supported in the center of the reserved position of the wire wheel 3 by a bearing bracket 7 connected to the frame body 1. The bearing bracket 7 is fixedly supported in the middle of the bearing 4, and the bearings on both sides Each of the 4 is equipped with a cable wheel 3, which satisfies the requirement that the collection/release of the test line is not necessarily performed synchronously, and the operation is convenient and fast. Pulleys 11 are arranged at both ends of the safety shaft hole of the wire pulley 3, and a handle 5 is provided on the outer side plate of the wire pulley 3, which greatly improves the rotatability and operability of the wire pulley 3 on the bearing 4. The test line 6 is wound on the reel 3, which eliminates the phenomenon of random winding when the test line 6 is manually collected/released. The staff can receive/release two test lines at the same time without keeping an eye on the test line 6, saving time , labor-saving, making the work of receiving/releasing the test line more convenient and efficient, and effectively improving work efficiency.

The existing test rod 8 is provided with a terminal head 12 of a bolt structure, and the test line 6 ends are connected with an open connection ring 13. When working, the connection ring 13 at the test line 6 ends is stuck on the connection head 12 of the test rod 8, By tightening the screws, the test line 6 can be firmly fixed on the test rod 8, which solves the problem of poor contact between the test rod 8 and the test line 6. In order to prevent the damage caused by the hammer hammering the test rod 8 during operation, the upper end of the test rod 8 is provided with a head guard 9 that is larger than the radial cross-sectional area of the test rod 8. The head guard 9 is spherical (can also be elliptical) , square shape or polygonal shape, not limited to any one).

See Fig. 3: In order to avoid problems such as clutter and easy loss of tools for testing grounding resistance, the utility model is equipped with a box body 10, which is convenient for handling and moving. When in use, the frame body 1 is lifted out from the box body 10 (because the ground resistance meter 2 and the wire wheel 3 etc. are placed on the frame body 1, so when the frame body 1 is lifted out, the ground resistance meter 2 and the wire wheel 3 etc. The test tools are lifted out at the same time), and start the normal work of opening the ground wire, setting out the wire, fixing the test rod, and shaking the meter. When depositing, turn the line wheel 3 to take back the test line 6, put the frame body 1 in the casing 10, and other auxiliary tools (as auxiliary tools such as wrench and pliers) also put into, seal the case and carry.
