Abstract

The invention discloses a net side circuit high-voltage fuse of an electric locomotive. The net side circuit high-voltage fuse of the electric locomotive comprises melt, an arc-extinguishing medium, a pipe shell and amphenol connectors. The melt is arranged in the pipe shell, the space between the melt and the pipe shell is filled with the arc-extinguishing medium, and the amphenol connectors are arranged on the two sides of the pipe shell. According to the net side circuit high-voltage fuse, a fault circuit and an overhead line system can be disengaged in time, and therefore the overhead line system is prevented from accidents of burnout and breakage.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electric locomotives, in particular to a high-voltage fuse for a network side circuit of an electric locomotive. Background technique [0002] The 25kV grid side circuit of electric locomotive is mainly composed of pantograph, disconnector, main circuit breaker, high-voltage voltage transformer, high-voltage current transformer, lightning arrester, high-voltage connecting cable and high-voltage connecting rod, etc. It is an important part of electric locomotive. Once the high-voltage connection circuit or key high-voltage electrical appliances fail, the light one will cause the machine to break, and the serious one will cause the catenary to burn and break, which will affect the normal operation of other vehicles on the line, and the maintenance and rescue will be difficult and take a long time. Therefore, it is necessary to ensure that the electric locomotive The stability and relia...
