35kV变对线路交流短路融冰的方案研究

Study on AC short -circuited ice melting plan for 35kV main transformer on lines

利用10kV交流电源通过35kV主变降压后在对线路进行短路融冰的方法，现有35kV变电站内的设备进行简单连接后即可改造为安全可靠的融冰装置，在融完冰之后立即可恢复正常供电，无需其他投入，非常好的利用了现有变电资源，既不需对较大投入又能彻底的解决农网覆冰线路融冰问题。

By means of reducing voltage for 35kV main transformer, short - circuited ice melting for lines is carried out using 10kV AC power source, by simple linking devices which are in 35kV substation can reclaim to safest ice melting device, upon completion of ice melting, normal power supply can be achieved, dispense with other inputs, the plan makes good use of the currently existing power transformation resource, furthermore, it can thoroughly resolve ice melting problem for rural power network without larger investment.
