10KV以下户内油浸变压器,其高低压一侧的非安全区域常设置遮栏保护网,这是保证操作人员及设备正常运行的一项重要安全措施。过去,该保护网不但制作粗糙简陋,而且在变压器停电检修除尘去污时候,保护网必须连片拆卸挪动,给操作带来不便(图一)。在工程实践中,我们将原来的螺栓固定式改为窗框型串心铰链开启式(图二)。经工艺改进后显示如下优点: 1.轻巧新颖美观。 2.装拆简便。 3.检修方便。 4.有利变压器清扫去污,提高运行可靠性。
Below 10KV indoor oil-immersed transformers, the non-safety area on the high and low voltage side is often provided with a fence protection network, which is an important safety measure to ensure the normal operation of operators and equipment. In the past, this protection network was not only rough and simple, but also had to be dismantled and moved inconvenience to the operation when the transformer was out of service for dust removal and decontamination (Figure 1). In engineering practice, we changed the original bolt-fixed type to a window-frame type string hinge opening type (Figure 2). After the process improvement, the following advantages are shown: 1. Lightweight and novel and beautiful. 2. Easy to install and remove. 3. Easy to overhaul. 4. Advantageous transformer cleaning and decontamination to improve operational reliability.
