Description
技术领域technical field
本实用新型涉及供电系统使用的小型吊装设备，特别是一种操作简单、使用方便、工作安全的变压器有载分接开关吊装装置。The utility model relates to a small hoisting device used in a power supply system, in particular to a transformer on-load tap changer hoisting device with simple operation, convenient use and safe work.
背景技术Background technique
随着室内变电站的日益增多，主变压器在室内安装使用的情况也日趋增多，变压器是整个变电所中最重要的电气设备，而变压器的有载分接开关起着调节变压器输出电压的作用，是整个变压器的“心脏”。有载分接开关对变电所的供电电压稳定性和合格率起到至关重要的作用。有载分接开关一般安装在变压器的筒体内部是使用法兰进行连接，而且变压器器身很高，所以，需要使用起重设备才能使分接开关安全得从筒体吊至地面。同时，有载分接开关中较重的V 型开关重量有40KG，较轻的M型开关达到20KG，使用人力将开关抬至地面非常困难，而且开关是精密设备，抬递过程中如果发生碰损意外，都会给开关性能造成很大的损害，并且变压器上方作业空间狭小，变压器油洒落后，变压器顶部湿滑，不利于人员在上方进行作业。因此，目前急需一种能够在变压器上方安装使用的起吊装置，来解决室内变压器无法使用起重设备的问题。With the increasing number of indoor substations, the installation and use of main transformers indoors is also increasing. The transformer is the most important electrical equipment in the entire substation, and the on-load tap changer of the transformer plays the role of adjusting the output voltage of the transformer. It is the "heart" of the whole transformer. On-load tap-changers play a vital role in the stability and qualification rate of power supply voltage in substations. The on-load tap-changer is generally installed inside the cylinder of the transformer and connected by flanges, and the transformer body is very high, so lifting equipment is required to safely lift the tap-changer from the cylinder to the ground. At the same time, the heavier V-type switch in the on-load tap-changer weighs 40KG, and the lighter M-type switch reaches 20KG. It is very difficult to lift the switch to the ground by manpower, and the switch is a precision device. Any damage or accident will cause great damage to the switch performance, and the working space above the transformer is narrow, the transformer oil is spilled, and the top of the transformer is wet and slippery, which is not conducive to personnel working on it. Therefore, there is an urgent need for a lifting device that can be installed and used above the transformer to solve the problem that the indoor transformer cannot use lifting equipment.
