Double-spectrum helmet display

Abstract

The embodiment of the invention discloses a double-spectrum helmet display applied to corona detection, which comprises an ultraviolet light path and a visible light path, wherein the ultraviolet light path comprises an ultraviolet object lens, an ultraviolet image intensifier, an ultraviolet optical filter and a first eyepiece, wherein the ultraviolet image intensifier is connected with the ultraviolet object lens; the ultraviolet optical filter is arranged between the ultraviolet object lens and the ultraviolet image intensifier; the object plane of the first eyepiece is connected with the output surface of the ultraviolet image intensifier; the visible light path comprises an object lens, a second glimmer image intensifier and a second eyepiece; the object lens is used for picking up a visible light image of an outside scene; the second glimmer image intensifier is connected with the object lens; and the object plane of the second eyepiece is connected with the output surface of the second glimmer image intensifier. The double-spectrum helmet display can be used for finding the corona phenomenon at night in time and can be worn when a power system is maintained so as to greatly avoid the loss of the power system; and the helmet display has the advantages of high detection efficiency, convenience in carrying, high accuracy and fewer influences from an outside environment.

Description

technical field [0001] The invention relates to the technical field of head-mounted display manufacturing, in particular to a dual-spectrum head-mounted display for corona detection. 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 will facilitate t...

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.
