Drawings
The present invention will be described in further detail with reference to the accompanying drawings:
fig. 1 is a schematic structural diagram of the present invention;
in the figure, the clamp comprises a clamp body 1, a clamp body 2, a connecting piece 3, a spring piece 4, an inserting piece 5, an adapter, 6, a pin 7, an engaging claw 8, an engaging hook 9, a disc 10, a blind hole 11 and an insulating holding sleeve.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings and examples.
Examples
Referring to fig. 1, a portable electric energy quality testing tool comprises a clamp body 1, a connecting piece 2, a spring piece 3, a plug-in 4 and an adapter 5; the clamp body 1 is made of manganese steel into an arc shape, and is made of manganese steel materials, so that the strength is ensured; the upper part of the arc-shaped clamp body 1 is provided with two pins 6 which are connected through a connecting piece 2 made of resin insulating material, and the connecting piece adopts resin material as insulating and connecting material, so that the mechanical strength of the equipment can be ensured while the insulation is ensured, meanwhile, the quality is lighter, and the use is more convenient; the connecting piece 2 is embedded in the clamp body 1; the two sides of the two pins 6 are respectively provided with a spring piece 3, the spring pieces 3 are embedded into the clamp body 1, the middle parts of the clamp body 1 and the connecting piece 2 are provided with through holes, one end of the copper plug-in 4 penetrates through the through holes, and the other end of the copper plug-in 4 is connected with the adapter 5.
The clamp is characterized in that saw-tooth-shaped engaging claws 7 are arranged on two sides of the lower part of the clamp body, and engaging hooks 8 are arranged at two ends of the clamp body.
The plug-in components be the cylindrical rod body, the bottom of the cylindrical rod body is the disc 9 that the diameter is greater than the body of rod.
The head of the adapter is a convex metal needle, and the metal needle is inserted into the plug-in unit; the afterbody of adapter is the metal cylinder, and the metal cylinder sets up blind hole 10 by the terminal surface downwards, and the insulating cover of gripping of metal cylinder's outer wall suit 11.
During the use, whether it is good to detect plug-in components and adapter with the universal meter earlier, and the spring has or not hard up phenomenon, guarantees the reliability of device when the purpose of this operation is ensured live working, can not take place the electric leakage accident, causes personnel to take place to electrocute danger.
After the reliability of the device is determined, a tested terminal is found in the power distribution cabinet, then the two pins of the clamp body are clamped by the thumb and the index finger of the right hand, the front claw of the tool is opened through the connection of the spring piece, the plug-in is accurately aligned to the central jack of the tested terminal and inserted into the plug-in, and then the two pins of the clamp body are slowly loosened, so that the front claw of the tool is accurately meshed with the two ends of the tested terminal. And clamping one of the two pins of the clamp body by using a thumb and an index finger of a right hand, shaking along the direction vertical to the plug-in unit, and checking the meshing condition of the front claw of the tool and the tested terminal. If the looseness appears, the steps are repeated until the front claw of the tool is tightly meshed with the tested terminal.
After the front claw of the tool is tightly meshed with the tested terminal, a meter pen of the measuring instrument is inserted into the adapter blind hole, and whether the looseness phenomenon exists is checked. If the looseness exists, whether the meter pen is worn or not or whether the meter pen is replaced needs to be checked. And after the meter pen is confirmed to be stably contacted with the adapter, connecting the other meter pen with a measured point of the equipment connected with the measured terminal, and reading data after the data of the measuring instrument is stable. And performing power quality analysis according to the read actual data.
After the measurement is finished, firstly, the gauge pen on the side of the equipment connected with the terminal to be measured is detached, placed and well insulated. And then slowly removing the meter pen connected with the adapter. The pointer pen can not be too forcefully violent in the process of detaching the pointer pen, so that the durability of the pointer pen and the adapter is prevented from being reduced due to mechanical friction. Meanwhile, due to inertia, the force application process can cause the meter pen to scratch field workers.
After the meter pen is safely disassembled, the two pins of the clamp body are clamped by a thumb and an index finger of a right hand, and two front claws of the device are separated from contact with the tested terminal. The clip is then slowly pulled outward. After the device is completely separated from the tested terminal, the thumb and the forefinger of the right hand are released, the device is reset through the spring piece and is placed in a specified tool box, and the device is convenient to use next time.
