The invention discloses an automatic switching controlling device of neutral sections. By means of the automatic switching controlling device, the neutral section passing problem of two types of electrified railway locomotives is completely solved by overhead line systems themselves, and locomotive electrified neutral section passing is irrelevant to drivers and driving. The automatic switching controlling device is composed of an online phase separation section, current mutual conduction signal collectors (21, 22 and 23) or voltage mutual conduction signal collectors (24 and 25) and a switching control compartment. Overhead line system sections at different positions are connected in a lap joint mode and skid off through head bows and tail bows, current or voltage control signals which are supplied in a delayed and switched mode and reset are sequentially collected, the working states of normally open switches (31 and 32) and a normally closed switch (33) are controlled by a control system (35) through programs, a current limiter (34) is regularly connected into and retreats from a traction power supply circuit, and the monitoring of the delayed supply process, the load breakage process, the switched supply process, the current limiting process, and the reset process and the running state is automatically achieved through the cooperation of pantograph envelope sections (L1, L2, L3 and L4) and delayed supply process sections (L5 and L6), wherein the lengths of the pantograph envelope sections and the lengths of the delayed supply process sections meet the neutral section passing functional requirements.
