Abstract
The utility model discloses a connecting device for an electric power equipment ground wire. The connecting device is composed of an aluminum crimping head (1), nuts, a screw (3), an iron screw cap (5) and a connecting steel plate (6); the aluminum crimping head (1) is provided with a crimping hole and an aluminum crimping head screw hole; two ends of the screw (3) are respectively provided with right-handed and left-handed threads; and the iron screw cap (5) is welded with the connecting steel plate (6). When the connecting device is used, an aluminum conductor led out from a neutral point of a transformer is inserted into the crimping hole of the aluminum crimping head (1) to be crimped, a grounding round steel is welded on the connecting steel plate (6), the screw (3) is screwed tightly and simultaneously screwed into the aluminum crimping head screw hole and a screw hole of the iron screw cap, and then the screw (3) is fastened tightly through the upper nut (2) and the lower nut (4) after screwed tightly. Screw transition screwing connection is arranged between the aluminum and the iron, contact area is large, conductive performance is good, antirust capability is high, and disassembly and maintenance are convenient.
Description
Technical field
The utility model relates to a kind of power equipment ground wire connecting device, is specifically related to a kind of ground wire connecting device of transformer neutral point.
Background technology
Power equipment shell, transformer neutral point are generally all wanted ground connection, especially transformer neutral point ground connection must be firm, transformer neutral point is generally drawn with belt leather aluminum steel at present, be connected with screw with grounded round steels at ground place, because grounding screw gets rusty easily, add all easily oxidations of iron and aluminium, contact resistance strengthens gradually, be easy to cause fracture, jeopardize Electrical Safety.Mono-kind of Chinese patent CN201311974Y screws type ground connection and fastens, between inverted T-shaped ground connection termination and solid earth stud body, screw and be connected with six square nuts, rainwater can enter the gap between T shape ground connection termination and six square nuts, causes oxidation corrosion, and therefore it will join rainhat.
Summary of the invention
The purpose of this utility model is to overcome the problems referred to above, and a kind of antirust, rainproof, power equipment ground wire connecting device that conductivity is strong is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of power equipment ground wire connecting device, by aluminium crimp head (1), nut, screw rod (3), iron nut (5), junction steel plate (6) composition, it is characterized in that: in aluminium crimp head (1), have crimping hole (8) and aluminium crimp head screw (9), there is hexahedron at screw rod (3) middle part, two ends just have, anti-silk, screw rod (3) just, on anti-silk, be rotary with respectively top nut (2) and lower nut (4), on iron nut (5), there is iron nut screw (10), on iron nut (5), be welded with junction steel plate (6), junction steel plate (6) upper porose (7).
When use, transformer neutral point is drawn to the aluminum conductor that gets off to be inserted in the crimping hole (8) of aluminium crimp head (1) and carries out crimping, grounded round steels is welded on junction steel plate (6), screw screw rod (3), because screw rod (3) has respectively positive and negative silk up and down, screw rod (3) can screw in aluminium crimp head screw (9) and iron nut screw (10) simultaneously, screws rear stiff tight respectively with top nut (2) and lower nut (4).
The utility model compared with prior art has the following advantages:
1, between ferro-aluminum, connect by screw excessive screwing, contact-making surface is large, conducts electricity very well;
2, due to the screw on aluminium joint down, can not intake, do not need to join rainhat, antirust ability is strong;
3, screw can not become rusty extremely, and detachable maintaining is convenient.
