Double-spectrum helmet display system

Abstract

The embodiment of the invention discloses a double-spectrum helmet display system used for corona detection, which comprises an ultraviolet objective lens, an ultraviolet image intensifier, an ultraviolet optical filter, a first fiber image transmitting beam, a first ocular lens, a first spectroscope or first reflector, an objective lens, a second shimmer image intensifier, a second fiber image transmitting beam, a second ocular lens, and a second spectroscope or second reflector, wherein the ultraviolet optical filter is arranged between the ultraviolet objective lens and the ultraviolet image intensifier; the first spectroscope or first reflector is connected with the first ocular lens; the objective lens is used for capturing an visible light image of external scenery; the second spectroscope or second reflector is connected with the second ocular lens; after light reflected by the second spectroscope or second reflector enters into the eyes of a user, the virtual image of the external scenery seen by the eyes of the user is at the position with the external scenery. By using the device, the corona phenomenon can be found timely in night. The detection efficiency is high. The helmet display system is portable, is high in accuracy and is hardly influenced by the external environment. By taking the helmet display system in the process of repairing the electric power system, the loss of the electric power system is greatly avoided.

Description

technical field [0001] The present invention relates to the technical field of head-mounted display system manufacturing, and more specifically, relates to a dual-spectrum head-mounted display system. Background technique [0002] In recent years, my country's economy has continued to develop at a high speed and steadily, and the scale of the power system has also continued to expand. With the implementation of my country's west-to-east power transmission plan, the transmission voltage level has gradually increased, and 500kV transmission lines and substations have been settled in various parts of the country. Ultra-high voltage Power transmission and transformation systems are widely used, and it is even more important to maintain their safe and reliable operation. Corona discharge will not only seriously affect personal and equipment safety, but also cause a large amount of power loss. Therefore, timely and accurate detection of the location and strength of corona discharge...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, infrared telescopes, infrared cameras or ultraviolet cameras are mainly used to inspect power transmission and transformation lines at night. However, the target of corona discharge is small and weak, and visual observation is difficult. Although the solar radiation is weak at night Under certain circumstances, ultraviolet cameras can also be used to detect corona activity, but this detection process is difficult to operate, inefficient, and expensive; and, because infrared equipment detects heat, when infrared equipment detects electricity When the corona phenomenon occurs, the power line or equipment has been seriously damaged due to corona. It is difficult to detect corona in time at night by using the above method, and then the power system cannot be maintained in time, resulting in unavoidable losses.
