Double-spectrum helmet display device

Abstract

The embodiment of the invention discloses a double-spectrum helmet display device applied to corona detection, which comprises an ultraviolet optical path and a visible light optical path. The ultraviolet optical path comprises an ultraviolet objective, an ultraviolet image intensifier, an ultraviolet optical filter, a first optical fiber image transmitting bundle, a first ocular and a first spectroscope or a first reflector, wherein the ultraviolet image intensifier is connected with the ultraviolet objective; the ultraviolet optical filter is positioned between the ultraviolet objective andthe ultraviolet image intensifier; and the first spectroscope or the first reflector is connected with the first ocular. The visible light optical path comprises an objective, a second micro image intensifier and a second ocular, wherein the objective is used for shooting a visible light image of an outside scene; the second micro image intensifier is connected with the objective; and an object plane of the second ocular is connected with an output surface of the second micro image intensifier. The device can discover the corona phenomenon timely at night, has high defection efficiency, is convenient to carry and has high accuracy rate. The influence of the outside environment on the double-spectrum helmet display device is low. The double-spectrum helmet display device can be worn in theprocess of maintaining a power system so as to greatly avoid the loss of the power system.

Description

technical field [0001] The present invention relates to the technical field of manufacturing head-mounted display devices, and more specifically, relates to a dual-spectrum head-mounted display device. 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 discharg...

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.
