[0003] Most of the existing oscilloscopes are equipped with wiring holes. The wiring holes are used to connect external signal lines, which is convenient for the equipment to measure power signals through the signal lines. However, on the existing oscilloscopes, the wiring holes are mostly directly exposed, and some dust and impurities are easy to enter. In the hole, the contact between the signal line and the wiring hole is affected. At the same time, in the actual measurement process, due to the lack of corresponding fixing devices, the signal line is prone to loosening on the wiring hole, resulting in frequent fluctuations in measurement and poor measurement accuracy.

Embodiment Construction
[0027] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.
[0028] Such as figure 1 As shown, a high-accuracy electrician measuring equipment for electric power maintenance includes a housing 1 with a display screen 2, a number of operation keys 3, a number of knobs 4, and a number of wiring devices;
[0029] When electricians use the power measurement equipment, they connect the external signal line through the wiring device and use the knob 4 to adjust. After pressing the operation key 3, the display 2 displays the power information for the electrician to observe.
[0030] Such as figure 2 As shown, the wiring device includes a wiring hole, a pillar 5, a sealing mechanism, and a fixing mechanism. The wiring hole is arranged on th...

The invention relates to high-accuracy electrical measuring equipment for power maintenance. The high-accuracy electrical measuring equipment for power maintenance comprises a shell; a display screen,several operation keys, several knobs and several wiring devices are arranged on the shell; the wiring device comprises a wiring hole, a support column, a sealing mechanism and a fixing mechanism; the sealing mechanism comprises a flat plate, a sealing plate, a pull assembly and four connecting rods; the pull assembly comprises a pull ring, a pull rod and a first spring; and the fixing mechanismcomprises a driving assembly, a sleeve and several fixing assemblies. According to the high-accuracy electrical measuring equipment for power maintenance in the invention, due to the sealing assembly,when the equipment is idle, the wiring hole is sealed and dustproof; therefore, good contact between the wiring hole and a signal line in measurement can be ensured; the detection accuracy is increased; furthermore, the signal line is fixed in the wiring hole through the fixing mechanism; therefore, loosing is prevented; deviation generated in measurement is avoided; the signal line is fixed, sothat the measurement precision is ensured; and thus, the practicability of the equipment is improved.
Description
Technical field [0001] The invention relates to the field of electrical equipment, in particular to an electrical measurement equipment with high accuracy for power maintenance. Background technique [0002] The oscilloscope is a very versatile electronic measuring instrument. It programs visible images of electrical signals that are invisible to the naked eye, which is convenient for people to study the changing process of various electrical phenomena. The oscilloscope uses a narrow electron beam composed of high-speed electrons to hit the phosphor-coated screen to produce tiny light spots. The oscilloscope can be used to observe the waveform curves of various signal amplitudes changing with time, and it can also be used to test different electrical quantities, such as voltage, current, frequency, phase, amplitude adjustment, etc. The oscilloscope usually helps electricians perform electrical measurements for electricity Various measurements of the system. [0003] Most of the ...
