Abstract

本实用新型公开了一种高压电容柜，该电容柜的主框架用FA38型材拼接而成，型材相互间的搭接采用铝三通和铝单通，保证了柜体整体上的强度和刚度。主安装支架为敷铝锌板压边折弯，元件安装支架用3mm厚的镀锌板，元件分三层放置，包含了真空接触器、放电线圈、电抗与电容等元器件。由于本实用新型使用型材拼接后使整个柜子结构紧凑、布局合理，即保证了使用要求，又简化了生产过程。

Description

高压电容柜
技术领域
    本实用新型涉及电压等级输变电***配电柜领域，具体是一种应用于10KV配电***就地无功补偿的电容柜。 
背景技术
    电容柜是10KV配电***常用到的设备，起到***就地容性无功补偿的作用，以提高***的功率因数，与***本身而言具有相对的独立性，可以不同于原***的柜型结构，在满足使用要求的前提下，如何简化产品结构，降低生产成本。发明人对以上要求，开发了应用FA38型材为主体框架的电容柜。 
发明内容
本实用新型的目的在于提供一种应用于10KV配电***就地无功补偿的高压电容柜。 
本实用新型的技术方案：本实用新型的高压电容柜的主框架用铝三通连接在一起，并用连接板加固，第一隔挡和第二隔挡用铝单通搭接在主框架上，安装支件固定在第二隔挡上，安装元器件的横支件固定在安装支件上；真空接触器和电流互感器放置在柜体的上层，避雷器接于电流互感器分支铜排上，底层并列放置电抗器和电容器，放电线圈放置在底层和上层之间，电容器连接在电流互感器和电容器之间，放电线圈通过软连接并联在电容器两端，并从放电线圈接分支铜排至电抗器。 
本实用新型在安装搭框架时，先搭上、下底面的四边形框架，经过对角线找正后，再搭接四根立柱，这样有助于保证整个框架的对角线误差。整个框架采用FA38型材搭接。本实用新型在使用时，电抗器、电容器放置在柜体的底层，呈并列放置；顶层前面靠仪表室位置放置真空接触器，顶层后部放置电流互感器（采用侧装式安装），铜排从电流互感器出来后，经带电传感器支撑，在通过熔断器和电容器连接。另外再接一个支路到避雷器。放电线圈放置于底层的电抗器、电容器和顶层的真空接触器、电流互感器之间。在纵向位置上和熔断器位置错开，以便于和电容器两端连接，达到和电容器并联的目的。放电线圈到电容器的铜排中间用绝缘子固定，末端用软连接与电容器连接，避免了和电容器的刚性连接。放电线圈另引出一段接到电抗器。 
本实用新型的整个框架采用FA38型材搭接，型材可以从型材厂家直接购买，自身只需加工隔板、门、封板及各安装支件。这样能使整个柜子结构紧凑、布局合理，保证了使用要求，又简化了生产过程，加快了生产周期。
