In electric power distribution, automatic circuit reclosers (ACRs) are a class of switchgear designed for use on overhead electricity distribution networks to detect and interrupt transient faults.

2018年9月24日 · The OCR is an oil filled recloser which requires regular oil maintenance. Manufacturers typically recommend that utilities inspect, clean, and fill the recloser with new oil every three to six years. Since the OCR uses oil to operate, it is not environmentally friendly.

Eaton provides reliable, self-contained distribution-circuit overcurrent protection at low initial cost, while requiring minimal service with its Cooper PowerTM series Types E, 4E, V4E, H, 4H, V4H, L, and V4L single-phase reclosers and Types 6H and V6H three-phase reclosers.

Automatic circuit reclosers are recognized by electric utilities throughout the world as an essential device for achieving their prime goal: providing maximum continuity of electric service to their …

The lean design results in a minimal footprint of only 6,2 meters width (pole to pole). In case reduced space is available, the portals can be placed staggered so that even less space is required. As such, the space is optimally used. Other key features include: Can stand out in the open with no canopy required

For example, “b” designates a steel, pole top pin. The borrower may use, at its discretion, any of the applicable pole top pins from category “b” of the “List of Materials.” Similarly, the drawings of the bulletin show the use of three, 4 1/4 inch, ANSI Class 52-9A suspension insulators for 24.9/14.4 kV primary deadends.

OCR是一个简称，全称叫Optical Character Recognition，中文是： 光学字符识别 。 它的本质是：把图像形状转变为文本字符。 我们常见的各种证件识别、名片识别、车牌识别等，也涉及OCR技术。

Multifunction recloser system for distinct single and three phase programs. Time synchronization (PC or GPS synch.) The recloser portion of the DRS provides both single pole and three pole reclosing for one or two breakers. The reclosing sequence can be set to any of 7 programs: prior to the expiration of the reset time.

2024年6月21日 · Compared to other data-driven methods (HRNet-OCR and Deeplabv3+ ), our algorithm shows a state-of-the-art performance at understanding diverse leaning utility poles, which is practical and feasible in the visual inspection of power distribution infrastructures.

光学字符识别 （Optical Character Recognition, OCR）是指对文本材料的图像文件进行分析识别处理，以获取文字和版本信息的过程。 也就是说将图象中的文字进行识别，并返回文本形式的内容。 随着 ocr技术 的日渐成熟，目前github中有很多开源项目可供选择，下面将介绍几种常用的开源ocr项目。 1. Paddle OCR（推荐指数：★★★★★） 飞桨首次开源文字识别模型套件 PaddleOCR，目标是打造丰富、领先、实用的文本识别模型/工具库。 最新开源的超轻量PP …
