Embodiment 3
As shown in Figure 1, a kind of multifunction test trolley for electric power tool resistance test of the utility model, in embodiment
On the basis of 1, ground connection drum 5 is using flexible drum.17 termination of earth lead of ground connection drum 5 is connected with lug wire section 18,
Described 18 1 terminations of lug wire section are equipped with flat mouth folder 19.
The work efficiency of school examination is lifted, the school examination quantity of increase single is not only, need to also set about from experiment process.Conventional
In experiment, testing crew determines ground terminal to the distance (10kV of live end firstly the need of with meter ruler：0.7 meter, 35kV：0.9 meter,
110kV：1.3 meters) 1., then wound and be grounded with annealed copper wire, so that applied voltage test.If branched equipment carries out experiment at the same time, every
Ranging can increase the school examination time respectively, often draw copper wire winding ground connection and can increase the school examination time, plus the mode of copper wire winding
During site clearing is completed in operating process and experiment the problem of copper wire is wound mutually easily occurs for ground connection, largely effects on
Work efficiency；Batch school examination in, operating personnel repeatedly ranging, ground connection, can also increase operating personnel's labor intensity, so as to produce peace
Draw trouble entirely.To solve this problem, maintenance crew proposes several imaginations.First, processing and fabricating is grounded copper ring, copper ring is using buckle
Mode close, avoid copper wire winding time-consuming and laborious, but it is following have a new problem again, many insulated operating rods in market, test
Electroprobe, ground operation bar and non-standard, shank diameter have differences, and the copper ring of same size cannot be guaranteed to be suitable for all subjects
Equipment, production cost can be produced and be not easy to preserve again by processing the copper ring of different inner diameters；Second, design circlip, equally
It is to be influenced by test item diameter is inconsistent, maintenance crew does not take this mode.Finally, by testing repeatedly, finding will for maintenance crew
Copper wire is cut into mono- section of 10cm (lug wire section 18), and during experiment, copper wire is enclosed around the body of rod one, and tail end flat mouth is clamped, this
Sample not only ensure that the insulated operating rod, electroscope, ground operation bar of different-diameter can reliable ground, but also eliminate long copper wire and twine
Around the trouble brought.Drum 5 is grounded using flexible drum, stretch drum on the market will matured product sale, stretch drum just
Can voluntarily it withdraw with terminal box, solving the problems, such as more piece-root grafting ground wires cross winding at the scene.2 meters of spread length, also may be used
Easily to try 110kV voltage class tested devices in school, divide problem with grounding during three sections of experiments.
Above-described embodiment, the purpose of this utility model, technical solution and beneficial effect have been carried out into
One step describes in detail, it should be understood that the foregoing is merely specific embodiment of the present utility model, is not used to limit
Determine the scope of protection of the utility model, where within the spirit and principles of the present invention, any modification for being made, equally replace
Change, improve, should be included within the scope of protection of this utility model.
