Embodiment 2, referring to fig. 1 to 7, is a second embodiment of the present invention, and unlike the previous embodiment, the embodiment provides a method for using an ac ice melting expansion type voltage regulator for a distribution line, which includes the following steps:
S1, collecting data required by ice melting of a transformer 1;
S2, analyzing the ice melting length of the line;

S5, starting an ice melting current to melt ice;
S6, after the end, the ice melting device is disconnected.
The current loop can be formed between three phases in the distribution transformer instead of forming the current loop only through the ice melting short circuit points, the phenomenon can cause the distribution of ice melting current of the distribution network line, namely the ice melting current output by the ice melting device can be gradually reduced along the line, the current can be far smaller than an expected value when reaching the tail end of the line, thus the expected ice melting effect can not be achieved, when the distribution network line adopts direct current ice melting, the direct current bias problem is caused in the distribution transformer because the resistance of the distribution transformer is very small, all distribution transformer high-voltage side switches along the line between the access point of the ice melting device and the short circuit points must be disconnected during ice melting, even the outside of the access point of the ice melting device, namely the distribution transformer high-voltage side switch on the other side of the ice melting short circuit point also needs to be disconnected, otherwise, the direct current loop is formed through the distribution transformer high-voltage side; therefore, before ice melting, the high-voltage side switch of the distribution transformer needs to be pulled and restored after ice melting is finished, when an alternating-current ice melting mode is adopted, although the direct-current magnetic bias problem does not exist, if the distribution transformer is not pulled, ice melting voltage can be conveyed to a user side through the distribution transformer, because the ice melting voltage is generally far lower than normal power supply voltage, the user can operate electric equipment in the uncharged state if the line is mistakenly in an uncharged state, and the personal safety is possibly threatened.
