Description

Technical Field

[0001] The utility model relates to the technical field of oscillographs, and particularly relates to a portable oscillograph. Background Art

[0002] An oscillograph is a professional device used to record the changes of signals such as voltage and current in a power system. In the past, power fault analysis mainly relied on manual recording and empirical judgment, which was inefficient and prone to missing key details. Modern oscillographs adopt digital technology and can continuously capture signal fluctuations at a high sampling rate, and even short-term abnormalities can be completely recorded. The device has a large-capacity built-in storage and can store data for a long time for subsequent analysis. With the advancement of the construction of smart grids, oscillographs already have functions of automatic data marking and preliminary analysis, can quickly locate the fault time point, and can be linked with other systems through a standardized communication protocol, becoming an important tool for power operation and maintenance.

[0003] While retaining professional detection capabilities, the portable oscillograph is optimized for on-site use requirements. It adopts a lightweight design and is equipped with a rechargeable battery, and can work independently without an external power supply, which is suitable for outdoor or temporary detection scenarios. The operation interface of the device is simple, and different voltage levels of measurement requirements can be quickly adapted through modular sensors, covering from low-voltage power distribution to high-voltage power transmission. The detection results can directly display key parameters such as harmonics and power factor, and generate reports that meet industry specifications, helping engineers to judge the device status on-site. Some models support wireless data transmission and can upload the results to the management platform in real time to achieve remote collaboration and quick decision-making, significantly improving the on-site work efficiency.

[0004] The patent document CN222439558U discloses a portable oscillograph with an anti-misoperation function, which is characterized in that it includes an oscillograph main body with a display screen and an operation panel on its surface, and an anti-misoperation component arranged on the oscillograph main body; through the provided side-opening protective shell, when the oscillograph main body needs to be used, the side-opening protective shell can be first flipped to cover the operation panel, avoiding accidental contact with the protruding buttons on the operation panel. At the same time, the recessed pressing part provided on the side-opening protective shell can continue to meet the operator's operation requirements for the oscillograph buttons after the side-opening protective shell covers the operation panel. The recessed buttons enable the operator to press the oscillograph buttons only when the finger is inserted into the interior of the movable kit, effectively avoiding the occurrence of misoperation events.

[0005] As in the prior art of the aforementioned patent, portable waveform recorders are generally equipped with a connecting cable along with the device body. However, the connecting cable of the aforementioned device is not designed with a designated place for it, which may lead to the connection cable being lost or damaged during the carrying process. Furthermore, the aforementioned waveform recorder does not have a protective shell, and during the carrying and moving process, it may also be subject to a series of accidents such as collisions, without adequate protection.

The protective cover 2 is equipped with a winding post 18; a latch (not shown in the figure) is provided between the protective shell 1 and the protective cover 2, which can be used to close and open the protective shell 1 and the protective cover 2. The protective shell 1 and the protective cover 2 can provide external protection for the waveform recorder body 4, ensuring that it will not be damaged during use. The handle 3 is designed to facilitate lifting and carrying of the device. The sealing ring 11 can play a waterproof role. By winding the connecting wire 20 on the winding post 18 inside the protective cover 2, the connecting wire 20 can be fixed in an orderly manner. Compared with the traditional method, this method is beneficial to the subsequent use of the connecting wire 20 and prevents the connecting wires 20 from tangling.
