A high-accuracy power measuring device for electrician measurement

Abstract

The invention relates to a high-accuracy electric power measuring equipment used for electrician measurement, which comprises a housing on which a display screen, several buttons, several knobs and several wiring devices are arranged, and the wiring device includes a wiring hole, a fixing column, a sealing Mechanism and fixing mechanism, the sealing mechanism includes a fixed plate, a sealing plate, a pulling assembly and four side bars, the pulling assembly includes a pull ring, a pull rod and a first spring, and the fixing mechanism includes a driving assembly, an annular tube and several fixing assemblies, which are used for Electricity measuring equipment with high accuracy in electrician measurement can seal the wiring hole to prevent dust when the equipment is idle through the sealing mechanism, so as to ensure good contact between the wiring hole and the signal line during measurement, and improve the detection accuracy. Not only that, but also through the fixing mechanism Fix the signal line in the wiring hole to prevent loosening and avoid deviation during measurement, and ensure the measurement accuracy by fixing the signal line, thereby improving the practicability of the device.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a high-accuracy power measurement equipment for electrical measurement. Background technique [0002] An oscilloscope is an electronic measuring instrument with a wide range of uses. It programs invisible electrical signals into visible images, 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 screen coated with fluorescent substances to produce tiny light spots. The oscilloscope can be used to observe the waveform curves of various signal amplitudes changing with time, and can also be used to test different electric quantities, such as voltage, current, frequency, phase, amplitude modulation, etc. Oscilloscopes usually help electricians to perform electrical measurements and are used for power System measurements.

Problems solved by technology

[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.
