Description

A self-retracting wire reel, combined multi-slot wire reel and grounding wire storage device

technical field

The invention relates to the technical field of electric power equipment, in particular to a self-retracting wire reel, a conjoined multi-slot wire reel and a grounding wire receiver.

Background technique

In the process of testing high-voltage electrical equipment in substations, grounding is an important link, which involves the accuracy of the test and the safety of equipment and personnel. The ground wire for electric power test is also called safety return wire, which is used to transfer high voltage directly to the earth, and is an important tool to ensure the staff when voltage appears unexpectedly on equipment and lines that have been powered off. The grounding wire generally has multiple branches, one of which is grounded, and the rest are also grounded. In order to meet different experimental requirements, the length of each branch is longer. If the grounding wire is not coiled after use, it will take a lot of effort to organize it next time The wire ends that get mixed together, and it cannot be used in the wild without grounding. In the prior art, due to the long length of each branch wire of the multi-branch grounding wire and the thinner wire diameter of the grounding wire, the probability of intersecting between the wires is relatively high, and the friction force increases, so it is extremely easy to be entangled and knotted during the storage process. It takes a lot of time and energy to distinguish the branch lines that are intertwined with each other. Taking the DC leakage test of a 110kV single-phase arrester as an example, the normal test time is 30 minutes. Connect the DC high voltage generator test device wiring and It usually takes about 10 minutes to take up the wire, and it takes 5 minutes to untie and store the grounding wire normally. Especially when the grounding wire is slightly knotted, it takes more than 10 minutes to untie the grounding wire once. Minutes, reducing the efficiency of line understanding.

The grounding wire storage device is an auxiliary device for storing the grounding device, which is widely used in the fields of electric power construction and electric power maintenance. Although the existing grounding wire storage device can provide the storage of the grounding wire, it is not advanced enough in the branch winding and automatic winding control of the grounding wire. The storage device, which sets a hollow rotating shaft that can be rotated manually in a box with moving rollers, realizes the winding of the grounding wire by rotating the hollow rotating shaft. Although the storage efficiency of the grounding wire is improved, due to a The hollow rotating shaft is used to complete the storage of multi-branch grounding wires. The position of each branch grounding wire is prone to overlap during the winding process, resulting in entanglement of the wires. In addition, in the field construction process, due to the large construction area, the length of the grounding wire is long, and the grounding wire is directly drawn from the box to connect to the high-voltage electrical equipment such as the substation during the test, resulting in the distance between the end of the grounding wire and the box. Farther away, due to the large resistance of the wire length, there is a phenomenon of insufficient power during rewinding, and rewinding is more troublesome.
