Electric locomotive high voltage network side cabinet

Abstract

The invention discloses an electric locomotive high voltage network side cabinet, including a main framework, a left closure plate, a right closure plate, a left door plate, a middle door plate, a right door plate, a lower cover plate I and a lower cover plate II. The left closure plate, the right closure plate, the left door plate, the middle door plate, the right door plate, the lower cover plate I and the lower cover plate II are fixedly arranged on the main framework. The main framework adopts a steel structure. The left closure plate, the right closure plate, the left door plate, the middle door plate, the right door plate, the lower cover plate I and the lower cover plate II adopt a resin-based glass fiber reinforcement composite material. According to the invention, the size of the network side cabinet is reduced, the cabinet structure is compact and reasonable, small machine room space is occupied, the thunder impact resistance performance of a locomotive is improved, and requirements for the overvoltage level of middle and high voltage electric appliances in circuits are reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of electric locomotives, in particular to a high-voltage network side cabinet of an electric locomotive. Background technique [0002] As the air pollution has become more and more serious in recent years, smog weather occurs frequently. Smog is a kind of dirt formed by condensing moisture with fine particles as the center. The locomotives running in haze weather, the dirt adheres to the surface of the high-voltage electrical appliances arranged on the roof of the electric locomotive, coupled with the air with high humidity, it is very easy to form frost on the surface of the high-voltage electrical appliances arranged on the roof of the electric locomotive The ice-like ice reduces the insulation performance of the high-voltage electrical appliances arranged on the roof of the electric locomotive, so that the scintillation discharge and the drop of the induced network voltage occur on t...

Problems solved by technology

The locomotives running in haze weather, the dirt adheres to the surface of the high-voltage electrical appliances arranged on the roof of the electric locomotive, coupled with the air with high humidity, it is very easy to form frost on the surface of the high-voltage electrical appliances arranged on the roof of the electric locomotive The ice-like ice reduces the insulation performance of the high-voltage electrical appliances arranged on the roof of the electric locomotive, so that the scintillation discharge and the drop of the induced network voltage occur on the roof of the electric locomotive, and even the phenomenon of burning the high-voltage equipment or contact network lines on the roof of the locomotive, Seriously affect the driving safety of locomotives
