Abstract
The utility model discloses a special portable testing wire take-up and pay-off device for a grounding net, which comprises a reversed V-shaped fixed bracket, a rotating roller wire coil and a rotating shaft, wherein the rotating shaft is mounted in the middle of the reversed-V-shaped fixed bracket through a rotating bearing; the rotating roller wire coil is sleeved on the rotating shaft; the key points of the device are that an aviation plug and a built-in foldable-type wire take-up and pay-off handle are arranged on the rotating roller wire coil, and the upper and lower ends of the reversed V-shaped fixed bracket take the shape of right-angle hooks. The take-up and pay-off device has reasonable structural design, good dynamic balance and high strength, does not block the wire, is durable in use, can achieve rapid take-up and pay-off of the testing wire, and adopts the aviation plug to be connected with the testing wire conveniently. The take-up and pay-off device solves the technical problem of single function in the prior art.
Description
Technical field the utility model belongs to the grounding net of transformer substation technical field of measurement and test, relates to a kind of portable grounding lattice special test line draw off gear, and signal and data line be put or be twined to this device can the fast speed exhibition.
Background technology is measured ground network ground resistance and is adopted the different-frequency measure method usually, the 3-5 that the electric current pilespacing is about the earth mat catercorner length from measurement point length doubly, the voltage pilespacing from be about the electric current pilespacing from 0.6 times, the voltage stake departs from the angle of electric current stake can be in 30 degree.The earth mat diagonal line is generally (100-300 rice), and then the electric current line needs about 1000 meters of retractable cable, and pressure-wire needs 600 meters of retractable cables, at present, special test line and draw off gear is not arranged as yet, needs the 2.0mm of the common about 50-100 rice of every segment length of the above free-hand folding and unfolding simultaneously of 5 people
2Cotton covered wire needs manually repeatedly to connect, and retractable cable difficulty, speed are slow, and work efficiency is low, and simultaneously because voltage, electric current line center coupling bad contact, test causes difficulty to grounding lattice, causes misjudgment easily.
The summary of the invention the purpose of this utility model is to solve prior art to exist retractable cable difficulty, speed slow, and ineffective technical matters provides a kind of portable grounding lattice special test line draw off gear, to overcome the deficiencies in the prior art.
To achieve these goals, the portable grounding lattice special test of the utility model line draw off gear comprises splayed configuration fixed support, transfer roller drum and rotating shaft, and rotating shaft is installed in the support bracket fastened middle part of splayed configuration by rolling bearing, and the transfer roller drum is sleeved in the rotating shaft; Its main points are that the transfer roller drum is provided with aviation connection-peg hole and the built-in Foldable handle of retractable cable, the support bracket fastened rectangular hook solid in two ends up and down of described splayed configuration.
The utility model reasonable in design, novelty, draw off gear have good dynamic balance, and the intensity height does not block line, and is durable in use, can not only realize the quickly retracting of testing wire, and can use the connection that the aviation connection-peg carries out testing wire easily.Solved the technical matters that there is function singleness in prior art.
Description of drawings Fig. 1 is the utility model structural representation;
Fig. 2 is the back view of Fig. 1;
Fig. 3 is the right elevation of Fig. 1.
The specific embodiment is with reference to Fig. 1, Fig. 2 and Fig. 3, and it comprises splayed configuration fixed support 2, transfer roller drum 1 and rotating shaft 4 the utility model, and rotating shaft 4 is installed in the middle part of splayed configuration fixed support 2 by rolling bearing, and transfer roller drum 1 is sleeved in the rotating shaft 4; Transfer roller drum 1 is provided with aviation connection-peg hole 3 and the built-in Foldable handle 5 of retractable cable, the rectangular hook solid in two ends up and down of splayed configuration fixed support 1.
What the utility model draw off gear was overall designs and produces and material: splayed configuration fixed support 2 adopts three-dimensional all steel portal frame; Transfer roller drum 1 adopts all steel gantry skeleton, and cladding material is selected insulcrete and aluminum alloy materials for use; Stainless steel material is selected in retractable cable handle 5, aviation plug, rotating shaft 4 for use; The overall long 260mm that is of the utility model, wide is 150mm, height is 300mm.
The utility model adopts three-dimensional all steel gantry skeleton structure, has good dynamic balance, and the intensity height does not block line.Engineering insulating material panel, indeformable fire-retardant, withstanding corrosion, high temperature low temperature is indeformable.The voltage tester line is designed to 1.5mm
2Red soft insulated wire, the testing current line is designed to 2.0mm
2Green soft insulated wire, then a transfer roller drum can be realized folding and unfolding 400m voltage tester line, or folding and unfolding 350m testing current line.
For avoiding voltage, electric current line center coupling bad contact, test causes difficulty to grounding lattice, cause misjudgment easily, the testing wire end is connected with the aviation connection-peg, be inserted at ordinary times in the aviation connection-peg hole 3 on the transfer roller drum 1, during test, in aviation connection-peg hole 3, extract, directly insert on the corrosion-resistant steel aviation socket of proving installation and get final product; Use built-in Foldable handle, can realize that the quickly retracting line is time saving and energy saving, can also prevent that testing wire is loose in the folding and unfolding moving process.
