Abstract
The invention provides a high-voltage electrical box which comprises an insulating box, wherein a corresponding high-voltage electrical apparatus is installed in the insulating box. The insulating box is small in volume and separates the high-voltage electrical apparatus from the external environment, so that the high-voltage apparatus is free from influence of the external environment, and the problem of high-voltage discharging of the high-voltage electrical apparatus at the top of an automobile in severe weather conditions can be effectively solved.
Description
Technical field
The present invention relates to a kind of High-Voltage Electrical Appliances case, belong to High-Voltage Electrical Appliances resist technology field.
Background technology
Because existing electric locomotive generally operates in the open environment, if running environment is abominable, the roof high voltage device will be subject to the weather influences such as rain, snow, ice, mist, and the electrion phenomenon takes place frequently.
Summary of the invention
The problem that the electrion phenomenon that the present invention causes because of harsh weather for the High-Voltage Electrical Appliances that solve existing electric locomotive takes place frequently, and then a kind of High-Voltage Electrical Appliances case is provided.For this reason, the invention provides following technical scheme:
A kind of High-Voltage Electrical Appliances case comprises insulated case, and corresponding High-Voltage Electrical Appliances are installed in the described insulated case.
The present invention uses insulated case with High-Voltage Electrical Appliances and external environment isolation, and High-Voltage Electrical Appliances are not affected by the external environment, and can effectively solve the electrion phenomenon of roof high voltage device under severe weather conditions.
Description of drawings
