Abstract
The utility model discloses an insulating sheath for a fall-off lightning arrester, which aims at solving the problem that a present fall-off lightning arrester tends to cause short circuit among phases. A positioning sleeve (4) is mounted at one end of a lock-catch mechanism sheath (1) and is integrated with the lock-catch mechanism sheath (1), cavities communicated with each other are respectively arranged in the lock-catch mechanism sheath (1) and the positioning sleeve (4), the lock-catch mechanism sheath (1) and the positioning sleeve (4) are cut along the axial direction, and a flange (2) is arranged at one end of the cut positions. Thus, the insulating sheath has the advantages of being not easy to age, being able to effectively prevent erosion of severe environment or lap joint of foreign matters or other conductive substances, and being convenient in operation and low in the maintenance cost.
Description
Technical field
The utility model relates to a kind of insulation system, relates in particular to a kind of drop-type arrester insulating sleeve.
Background technology
The existing lightning arrester kind of China is a lot, but drop-type arrester is as a kind of detachable and can overhaul in the situation that not having a power failure, and will more be popularized.When introducing, some problems have also been brought, as metal structure exposed on lightning arrester, at the long-term erosion due to adverse circumstances in service and the overlap joint of foreign matter or other conductive materials, all likely can cause alternate short circuit, cause immeasurable loss, it is necessary therefore for the hardware of drop-type arrester, formulating a relatively suitable sheath.
Summary of the invention
The purpose of this utility model is to provide and is a kind ofly difficult for agingly, can effectively prevent the erosion of adverse circumstances and the overlap joint of foreign matter or other conductive materials, easy to operate, the drop-type arrester insulating sleeve that maintenance cost is low.
For achieving the above object, the utility model drop-type arrester insulating sleeve, by latching device sheath and positioning sleeve, formed, positioning sleeve is arranged on latching device sheath one end and connects into an integral body with latching device sheath, in latching device sheath and positioning sleeve, be provided with the cavity that can mutually connect, latching device sheath and positioning sleeve are in axial direction disconnected, in gap one end, be provided with flanging.
Described latching device sheath is arranged to pentagon, on limit near positioning sleeve be provided with hypotenuse between adjacent another limit not disconnecting with it, on this hypotenuse, be provided with inspection hole, described latching device sheath cross section is arranged to square shape, the cavity in latching device sheath is also arranged to cross section square-shaped.
Described positioning sleeve comprises rectangular tube and trapezoidal cover, rectangular tube and trapezoidal cover form L shape, at positioning sleeve rectangular tube gap, be provided with inspection hole, the cross section of rectangular tube and trapezoidal cover is arranged to square shape, and the cavity of rectangular tube and trapezoidal cover is arranged to cross section is square.
On described flanging, be provided with a plurality of holes that clasp nail can be installed.
Described inspection hole is circular hole.
Described latching device sheath and positioning sleeve are made by silica gel.
Adopt after this structure, because positioning sleeve is arranged on latching device sheath one end and connects into an integral body with latching device sheath, in latching device sheath and positioning sleeve, be provided with the cavity that can mutually connect, latching device sheath and positioning sleeve are in axial direction disconnected, in gap one end, be provided with flanging; Latching device sheath and positioning sleeve are made by silica gel.Can reach thus and be difficult for agingly, can effectively prevent the erosion of adverse circumstances and the overlap joint of foreign matter or other conductive materials, easy to operate, the object that maintenance cost is low.
accompanying drawing explanationbelow in conjunction with drawings and Examples, the utility model is described in further detail.
