Abstract
The utility model discloses a wall-penetrating sleeve with a lightning protection function, wherein a lightning arrester is provided below the wall-penetrating sleeve, one end of the lightning arrester is connected with a conducting rod through a lightning attracting metal plate, and the other end is connected to the ground after being connected with the fixed metal plate of the wall-penetrating sleeve. A lightning protection function is provided, the independent installation of the lightning arrester is not required, the usage problem caused by independent installation of the lightning arrester and the wall-penetrating sleeve is solved, the construction link is simplified, and the safety and reliability of the electric appliance installation are guaranteed.
Description
Technical field
The utility model discloses a kind of wall bushing, relate to the protective device that power equipment is installed with lightning protection function.
Background technology
Wall bushing is widely used in electric power system power plant and transformer station's power distribution equipment and the high-voltage electrical equipment, and it act as: supply lead to pass ground dummy board, wall or electrical equipment shell, support that current-carrying part makes it over the ground or casing insulation.Wall bushing in use; The situation that frequent appearance and lightning arrester are used; When for example penetrating high voltage power cable, the lightning arrester of relevant voltage grade should be installed in sleeve pipe and cable junction additional according to relevant rules regulation, cable end can be occurred in this case in order to protect power cable through wall bushing; Sleeve pipe and lightning arrester are installed and are difficult for construction problem, influence equipment safety operation.
The utility model content
For overcoming above-mentioned technical problem, simplify construction link, the utility model provides a kind of wall bushing with lightning protection function.
For realizing above-mentioned technical purpose; The utility model is realized through following technical scheme: a kind of wall bushing with lightning protection function; It is characterized in that: in wall bushing conducting rod or the conductive plate below insulator a detachable lightning arrester is installed; The arrester ground end reliably is connected back ground connection with the wall bushing fixed metal plate, and the lightning arrester other end is connected with conducting rod through drawing the thunder metallic plate, draws thunder metallic plate and lightning arrester and is detachable.
The utility model also is applicable to compound inslation formula wall bushing.
The utlity model has following beneficial effect: when lightning current flows through this molded cannula, draw the thunder metallic object lightning current is introduced the earth through lightning arrester, play to the effect of power equipment lightning protection.The use of this utility model makes no longer independent installation of lightning arrester, and the use problem that occurs in the time of can solving lightning arrester and wall bushing independent installation has been simplified construction link, and it is safe and reliable to have guaranteed that power equipment is installed.
