style="text-indent:25px">合理選擇配電變壓器的安裝地點，該安裝地點應(yīng)盡可能靠近負(fù)載中心，并控制電源半徑在0.5km之內(nèi)。同時，盡量避免在閃電或低洼的水域安裝設(shè)備。由于位于縣城，路口處有很多變壓器，為了減少汽車撞到塔上，塔沿路全部粘貼防撞條標(biāo)志。盡量避免在配電變壓器上安裝低壓儀表箱。由于長時間運行，電表箱的玻璃損壞或無法及時更換變壓器的低壓樁頭。超過95％的公共配電變壓器都安裝了JP機(jī)柜，在保護(hù)變壓器的安全運行方面發(fā)揮了很好的作用。不允許在未經(jīng)許可的情況下調(diào)整分接開關(guān)，如果分接開關(guān)未調(diào)整到位并且發(fā)生相間短路，可能會燒毀配電變壓器。目前市場上變壓器測試儀主要類型分為多種，但具體的根據(jù)不同介質(zhì)來選擇適合自己的型號。</p><div
