我国经济的发展状况自改革开放以来就走向良好,国家全速发展生产力,将经济建设放在了首位,然而经济的发展也常常伴随着一些能源问题的出现。我国目前以煤炭资源为主要能源,所以在大力建设经济的过程中,各个领域都需要煤炭的运用,由此煤炭的消耗量逐渐上升,而其中联系最为紧密、使用最为频繁的便是电力方面。电力很大部分都来自煤炭的供能,而煤炭的开采也同样需要电力的支持。一般在煤炭开采的过程中是使用的高压线路,由此在供电运输的过程中经常会出现损耗,当损耗达到一定程度便会对煤炭开采造成困难和危险,所以在使用高压供电的时候,一定要注意线路的保护。而本文就是从高压供电线路保护的必要性着手,找出保护好高压供电线路的措施,以更好的促进煤炭安全有效的开采。 Since the reform and opening up, China’s economy has progressed well. The country has developed its productive forces at its full speed and placed economic construction in the first place. However, economic development is also accompanied by some energy problems. At present, China uses coal resources as its main energy source. Therefore, in the course of vigorously building its economy, the use of coal is required in all fields. As a result, the consumption of coal is gradually rising. Among them, the most closely linked are the most frequently used electricity sources. Much of the power comes from the coal supply, and coal mining also needs the support of electricity. Generally in the process of coal mining is the use of high-voltage lines, which in the process of power supply often appear loss, when the loss reaches a certain level of coal mining will cause difficulties and dangers, so when using high-voltage power supply, certain Pay attention to the protection of the line. This article starts with the necessity of high-voltage power supply line protection and finds out the measures to protect the high-voltage power supply line to better promote the safe and effective mining of coal.
