Abstract
The utility model is a kind of high voltage electric power equip ment sound intersity measurement probe composite shield cover.Comprise the exterior shield with electrostatic screening effect and have the elliposoidal polyfoam preventing interference in air flow, elliposoidal polyfoam is installed in exterior shield, and sound intensity probe is installed in the hollow cavity set by elliposoidal polyfoam.Sound intensity probe composite shield cover of the present utility model is simple and reasonable, light, easy for installation, is a kind of convenient and practical sound intensity probe composite shield cover.
Description
Technical field
The utility model relates to a kind of special sound intensity probe composite shield cover, in particular for protecting the sound intensity probe composite shield cover of the interference of high voltage installation highfield and interference in air flow.
Background technology
Sound intensity probe is a sensing element of sound-intensity measuring device, and current sound intensity probe only has hurricane globe to prevent air-flow on the impact of measuring.But when carrying out noise measurement to UHV (ultra-high voltage), extra-high voltage electric power equipment such as high-voltage shunt reactor, high-voltage commutation transformer, high-voltage flat-wave reactors, except the airflow influence of the cooling system of equipment, the highfield produced around equipment also can cause the measurement of sound intensity probe and have a strong impact on.Current sound intensity probe cannot be used for this occasion.Must shield highfield interference and interference in air flow in this occasion simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of sound intensity probe composite shield cover simple and reasonable, light, easy for installation.
Concrete technical scheme of the present utility model is: sound intensity probe composite shield cover of the present utility model, comprise the exterior shield with electrostatic screening effect and there is the elliposoidal polyfoam preventing interference in air flow, elliposoidal polyfoam is installed in exterior shield, and sound intensity probe is installed in the hollow cavity set by elliposoidal polyfoam.
The utility model compared with prior art, has following effect: sound intensity probe composite shield cover of the present utility model is simple and reasonable, light, easy for installation, is a kind of convenient and practical sound intensity probe composite shield cover.
