1. gw4-40.5高压隔离开关
GW5-110D型隔离开关常用于35～110KV户外配电装置中，用于开断线路轻负载电流，最后有一个D字，代表隔离开关上附有接地闸刀，由于户外隔离开关在比较恶劣的条件下工作，因此要求较高的绝缘水平，而且动静触头的分合要具备一定的破冰能力，以便可能在触头结冰的情况下实施操作。GW5系列隔离开关是由三个单极开关在现场安装时组合成三极的三相隔离开关。每相隔离开关由底座、两个实心棒形瓷柱和导电部分组成50°交角的V形结构。底座部分有两个轴承座，内装圆锥型滚动轴承，使瓷柱转动极为轻便灵活。两瓷柱通过伞形齿轮齿合，这样在操作任一瓷柱时，另一瓷柱随着同步反向转动，以达到开、合隔离开关的目的。导电刀闸分为两部分固定在两个瓷柱上，隔离开关的出线座采用可活动的结构，以保证在90°范围内灵活转动，并防止在操作隔离开关时引起母线振动。导电刀闸采用指形触头，分、合闸时触指间产生相对滚动，能起自身净化和破冰作用。GW5型隔离开关具有体积小、占地面积小、重量轻、使用可靠等优点，因此在35~110kV户外装置中得到广泛采用。具体参数见下表：

剪映是一款手机视频编辑工具，带有全面的剪辑功能，支持变速，有多样滤镜和美颜的效果，有丰富的曲库资源。自2021年2月起，剪映支持在手机移动端、Pad端、Mac电脑、Windows电脑全终端使用。
导入视频
打开剪映，点击创作，选择视频或图片，点击添加到项目，进入到编辑界面。
界面介绍
进入到编辑界面后，我们可以看到好多区域，分别为：预览区域，时间线区域，工具栏区域。
预览区域
分辨率
一般的剪辑手机视频，高清格式选择1080P或者720P都可以。
4K：高清的要死的那种，一般很少用到。
2K：高清的不行的那种，一般也不用。
1080P：人们所说的全高清，使用较多，一般意义上的高清的泛称。
720P：所谓的高清视频，高清的代理人，画质高清，运算更快，占盘更小。
480P：标清格式，之前电视视频的标准规范，现在很少用到了。
帧率
对于一般手机视频制作来说24～30都是可行的，帧速率越大，视频的内存也就越大。
一帧就是一张照片，视频就是由非常多的帧组成的。小时候经常在书本的右下角画一些人物，把书本合起来压着一个角翻页就形成一个动画，那么每一页就是一帧。帧速率是每秒翻多少页的意思，比如25帧就代表每秒钟翻25页。帧速率从24帧到60帧不等，越高越流畅，反之越卡顿，但高帧率也带来设备运行的高负荷，帧率一般24～30最常用。
放大
点击预览区域右下角放大图标，则可全屏预览视频，反之即可返回。
缩放和移动
进入编辑界面后，点击视频轨道，在预览区域，我们可以直接用俩个手指，在视频画面上进行放大，缩小和旋转，我们可以针对我们的需求，将视频画面自由移动到想要的位置。
时间线区域
时长调整
拖动时间轴，可以进行左右滑动播放。
点击视频轴，拖动尾部，即可缩短或拉长视频时长。（同理拖动开头也可以进行调整）。
点击音乐轴，拖动开头或者尾部可以调整音乐时长。
文字/贴纸/特效等素材也可以通过以上方式进行时长调整。
多轨道介绍
进入视频界面，视频所在轨道为视频轨道，以此类推，音频、特效、文本、贴纸都有对应的轨道。
音频、文本、贴纸可以同时拥有多条轨道，从而实现同时添加多条音乐和多种文本，各种贴纸的效果。
注意：特效轨道只有一条，不能叠加。
静音
进入编辑界面，在时间线区域，点击喇叭图标，关闭原声，可以把整段视频都静音了。
工具栏区域
静音
如果想要单独静音一段视频，点出二级工具栏之后，点击想要静音的一段视频，选择工具栏的音量，将音量调整为0，这样那段视频就可以静音了。
分割
进入视频编辑界面后，点击视频，下方出现二级工具栏，拖动视频，把想要分割的位置对齐白色指针，选择工具栏的分割，这个视频就被分割成两个片段了，我们可以针对两个片段来进行编辑。
注意：分割后的视频是可以前后调换顺序的，拖动向前向后放。
添加音乐
由于版权的限制，"剪映”APP并没有提供添加本地音频文件的功能，用户只能使用平台自带的音乐库添加音乐。也可以找公共领域音乐（著作权法规定作者过世50年后其作品不受版权保护，不过这种音乐最早也是50年前的估计不一定好用）或者CC0协议的音乐（CC协议即知识共享协议，CC0即代表作者自愿放弃作品财产权利，可以任意使用）。
点击视频，下方出现二级工具栏，选择音乐，四种添加方法如下：
1、出现音乐库，推荐音乐，可根据喜欢的类别选择音乐。
2、选择抖音收藏，登陆后可同步你在抖音收藏的音乐。
3、选择导入音乐，可复制其他音乐平台的音乐链接比如网易云音乐、qq音乐等，粘贴后导入即可。
4、提取视频中的音乐，比如在抖音下载了一个视频，下载后，点击提取音乐，选择视频导入，即可提取到音乐。
剪映制作效果
动画效果
导入视频之后，点击视频，选择二级工具栏，拖动并选中视频，选择工具栏中的动画添加向右甩入动画，根据需要调节的动画时长调节，就可以添加上动画了。
定格效果
进入创作界面后，点击视频，点开二级工具栏，拖动视频，把想要定格的位置对齐白色指针，选择下方工具栏的定格，这样就定格出一段视频。
出现效果：
转场效果
首先导入素材（最少导入2段素材），素材之间可添加转场效果。
在时间线区域，点击白色按钮，选择不同风格的转场特效，有基础转场、运镜转场、特效转场、和特殊转场。
每一个转场的时长均可调节。
成品：
画中画效果
进入编辑界面后，点击一级工具栏里的画中画。
选择新增画中画就可以在新的轨道里添加新的视频或图片。
画中画的素材可以任意移动和缩放。
上下分屏的视频可以使用画中画功能，只要把视频，移到上下一半的位置就可以了。
混合画中画
先看成品：
制作方法：
使用画中画的混合模式，导入一段下雪的素材。
点击画中画视频，出现二级工具栏 ，点击混合模式。
选择滤色就可以把素材的黑色背景去掉，留下想要的特效，就可以了。
音效效果
点击音频，出现二级工具栏，选择音效，会出现剪辑常用的音效库，点击使用就可以添加了。
卡点效果
进入界面后，选择音乐，在音乐库中选择一首适合卡点的音乐。
点击音频轨道，在下方二级工具栏里选择踩点，打开自动踩点，节奏会自动打在音频轨道上，可以选择不同踩节拍的模式。
自动踩点功能只适用于音乐库里的音乐和抖音收藏里的音乐，其他来源的音频，需要用户自己手动卡点，和直接选择踩点。
注意：根据音乐的鼓点，手动添加点就可以了。
拍同款
点击工具栏下方的剪同款。
进入界面后，可以看到不同分类的视频模板，选择一个你 喜欢的模板。
选择后，可预览模板视频，然后点击剪同款。
进去之后按照要求添加视频或图片，添加完成后点击进行下一步。
进入预览视频界面，如果想要替换某个片段，选中片段后，点击编辑。
点击替换，重新选择素材即可（文本也同理）。
编辑好之后，点击右上方的导出，就可以了。

4. gw4-35隔离开关
断路器的两侧均应配置隔离开关，以便在断路器检修时形成明显的断口与电源隔离。
中性点直接接地的普通变压器，均应通过隔离开关接地。
在母线上的避雷器和电压互感器，宜合用一组隔离开关，保证电器和母线的检修安全，每段母线上宜装设1-2组接地刀闸。
接在变压器引出线或中性点的避雷器可不装设隔离开关。
