Abstract
The utility model relates to a combination body for a single-pass bushing joint and an elbow type arrester, in particular to a single-pass arrester. A holding block (11) is arranged at the inner side of a copper terminal (13), an M4 screw rod (12) is inserted to be fixed from the side surface of the copper terminal (13), and a lower end cover (9) is screwed after the M4 screw rod (12) is arranged in a spring (10) to be contacted with the holding block (11). After the lower end cover (9) to be screwed is connected with an arrester core (8), the upper end of the copper terminal (13) is inserted from the lower end of a single-pass arrester rubber jacket (14). After a plug-pull seat (15) is inserted from the upper end of the single-pass arrester rubber jacket (14) along the copper terminal (13), an arc extinction pipe (16) is inserted into the plug-pull seat (15) to be fixed. The other end of the arrester core (8) is connected with an M10 screw rod (6), and a brass cover (7), an M10 nut (5), a ground wire terminal (4), a flat pad (3), a tile pad (2) and an M10 nut (1) are sequentially installed and fixed along the M10 screw rod (6). The utility model efficiently saves the space and the cost of a plug-pull connection system for an American box transformer substation and outdoor network cabinet high-voltage electricity.
Description
Affiliated technical field
The utility model relates to a kind of electric cable accessories that American case becomes, outdoor ring main unit high-voltage electrical apparatus can plug connected system, assembly of especially a kind of single-pass casing joint and elbow type lightning arrester of being used for.
Background technology
At present; when being used for the high-voltage electrical apparatus connection of American case change, outdoor ring main unit; for guaranteeing that electric equipment provides reliable overvoltage protection; guarantee electric power netting safe running; can plug connected system and adopt bilateral casing joint one an end adapter sleeve base, two interfaces of the other end of bilateral casing joint connect elbow type cable joint and elbow type lightning arrester respectively.To comprise accessory more and take up room greatlyyer because this can plug connected system, causes directly that American case becomes, outdoor ring main unit high-voltage electrical apparatus coupling part expense increases.
Summary of the invention
For effectively saving space and the expense that American case becomes, outdoor ring main unit high-voltage electrical apparatus can plug connected system, the utility model provides a kind of single-pass lightning arrester, is the assembly of a kind of single-pass casing joint and elbow type lightning arrester.American case becomes, outdoor ring main unit high-voltage electrical apparatus can plug connected system and adopt single-pass lightning arrester one end adapter sleeve base; the single-pass lightning arrester other end connects elbow type cable joint and can guarantee to guarantee electric power netting safe running for electric equipment provides reliable overvoltage protection.
Technical scheme
The single-pass lightning arrester is by being put into copper tip (13) inboard by withstanding tight block (11), usefulness M4 screw rod (12) inserts fixing from copper tip (13) side, after putting into spring (10) and withstanding tight block (11) contacting, screws with following capping (9).Following capping (9) to be screwed is inserted copper tip (13) upper end with after lightning arrester fuse (8) is connected from single-pass lightning arrester gum cover (14) lower end.After copper tip (13) inserted, it is fixing that arc-extinguishing tube (16) is inserted in plug seat (15) from single-pass lightning arrester gum cover (14) upper end for plug seat (15).Lightning arrester fuse (8) other end connects M10 screw rod (6), and brass lid (7), M10 nut (5), ground wire terminal (4), plain cushion (3), watt pad (2), M10 nut (1) are installed and fixed along M10 screw rod (6) successively.Single-pass lightning arrester gum cover (14) comprises insulated tube (17), inner conducting layer (19), insulating barrier (18) and outer conducting layer (20).The material of insulating barrier (18) is insulation EPDM, and the material of outer conducting layer (20) and inner conducting layer (19) is conduction EPDM.
American case becomes, outdoor ring main unit high-voltage electrical apparatus can plug connected system and adopt single-pass lightning arrester one end adapter sleeve base; the single-pass lightning arrester other end connects elbow type cable joint and can guarantee to guarantee electric power netting safe running for electric equipment provides reliable overvoltage protection.American case becomes, outdoor ring main unit high-voltage electrical apparatus can plug connected system space and expense have effectively been saved.
