Method and system for controlling high-voltage isolating switches of electric locomotive group

Abstract

The invention discloses a method for controlling high-voltage isolating switches of an electric locomotive group. The method comprises the following steps of judging the position of fault locomotive section in the electric locomotive group; and if judging that the middle locomotive section of the electric locomotive group fails to work, disconnecting the high-voltage isolating switches, close to the middle locomotive section, of the locomotive sections at the two ends and enabling pantograph of the locomotive sections at the two ends to be in a rising state. It can be shown that due to the adoption of the high-voltage isolating switch in the prior art, the locomotives with faults are isolated and the pantograph of the locomotive sections at the two ends are lifted through disconnecting the two high-voltage isolating switches close to the middle section while an electric fault happens on the middle section locomotive of the electric locomotive group; therefore, the operation capacities of the locomotive sections at the two ends are ensured so that the high-voltage isolating switches can be scientifically managed when the different locomotive sections fail to work so as to obviously increase the train operation efficiency. In addition, the invention further discloses a system for controlling the high-voltage isolating switches of the electric locomotive group, which has the same technical effect with the method and does not need to be repeated here.

Description

technical field [0001] The invention relates to the technical field of fault management of electric locomotive sets, in particular to a control method and system for a high-voltage isolation switch of electric locomotive sets. Background technique [0002] With the development of my country's railway transportation, the railway traffic lines are becoming more and more dense, and the railway transportation mainly uses electric locomotives as the traction locomotive, and the trains are driven forward by electricity. [0003] A kind of existing electric locomotive group, see figure 1 As shown, among them, the high-voltage isolation switches K1, K4 are used to isolate the fault pantograph, and K2, K3 are used to isolate the fault node. [0004] In the process of operation, the failure of the three vehicles is relatively complicated. In the prior art, a simple judgment condition is adopted: when the pantograph fails, the corresponding high-voltage isolation switches K1 and K4 ar...

Problems solved by technology

[0004] In the process of operation, the failure of the three vehicles is relatively complicated. In the prior art, a simple judgment condition is adopted: when the pantograph fails, the corresponding high-voltage isolation switches K1 and K4 are disconnected. For example, when the A vehicle fails, the disconnection Open the high-voltage isolating switch K1 of car A; when car B fails, disconnect the high-voltage isolating switch K4 of car B, it is difficult to reasonably configure the closing / opening state of the high-voltage isolating switch to isolate the fault situation, such as the main circuit failure of car C , loss of locomotive network nodes, etc. will cause locomotive parking and rescue, etc., and serious problems such as locomotive damage due to unreasonable coordination of high-voltage isolating switches
