Abstract
The utility model relates to an all-insulated metal-oxide lightning arrester of a complex outer sleeve type, which comprises a lightning arrester body connected with a wire lead, a conical sleeve and a flange, wherein the conical sleeve for the wire lead to penetrate is arranged at the upper end of the lightning arrester body, and the flange is mounted at the lower end; the wire lead adopts a high-voltage insulating cable lead with one end provided with a wiring terminal and the other end sealed in the conical sleeve and connected with the upper end of the lightning arrester body, and a tap grounding stud arranged at the lower part of the lightning arrester body penetrates through a lightning arrester outer sleeve and is sealed on the lightning arrester body so that external parts and the lightning arrester body form an all-insulated whole body. The lightning arrester not only reduces the amount of the parts, improves the manufacturability and compacts the lightning arrester, but also greatly reduces the air distance between adjacent lightning arresters, improves the creepage distance of the lightning arresters and extends the use of the lightning arrester to high-altitude and heavy-filthy localities through the flexible connecting structure, thereby being applicable to a switch cabinet with a limited space.
Description
Technical field
The utility model relates to a kind of metal oxide arrester, especially relates to a kind of all insulation composite sheath formula metal oxide arrester.
Background technology
The all insulation lightning arrester is the overvoltage protection device that the protection electric equipment is avoided atmospheric over-voltage or switching overvoltage damage.In existing technology; no matter be porcelain bushing type or silicon rubber composite sheath formula lightning arrester; one group of lightning arrester (3 phase) is installed in respectively between A phase, B phase, C phase line and the ground wire of protected equipment, and high-voltage terminal all is a metal, therefore must consider alternate air insulation distance when mounted.Because of the restriction that its volume is big, the installation site is subjected to the phase insulation distance, it is restricted on using, it is also very not convenient that terminals are installed in addition, thereby make troubles to client's use.Earth terminal need be installed insulator foot increases the lightning arrester height, and cost strengthens.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of number of components that reduces at above-mentioned prior art present situation, improve manufacturing, make lightning arrester densification more, be used to improve all insulation composite sheath formula metal oxide arrester of lightning arrester function, it can greatly dwindle the air distance between the adjacent lightning arrester, improve the creepage distance of lightning arrester, and by syndeton flexibly, make the lightning arrester expansion use high height above sea level, heavy pollution area, be particularly useful in the switch cubicle of the confined space.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this all insulation composite sheath formula metal oxide arrester, comprise the lightning arrester body that is connected with lead-in wire, the upper end of lightning arrester body is provided with can be for the taper sheath that goes between and pass, mounting flange is equipped with in the lower end, it is characterized in that described lead-in wire adopts the High-Voltage Insulation cable conductor, the one end is equipped with binding post, and the other end is sealed in the taper sheath and with the lightning arrester body upper end and is connected together; The tap grounding screw that is positioned at the lightning arrester body bottom passes the lightning arrester overcoat and is packaged on the lightning arrester body, and exterior part and lightning arrester body are formed the integral body of all insulation like this.
Compared with prior art, advantage of the present utility model is:
When 1, lightning arrester being installed, greatly dwindled alternate air distance, as long as binding post is connected on the corresponding phase line of protected equipment, lead-in wire can increase and decrease length according to actual needs during wiring, is convenient to assembling, is particularly useful in the switch cubicle of the confined space.
2, lead-in wire is the High-Voltage Insulation cable conductor, and is directly to draw from lightning arrester body, thereby has improved the creepage distance of lightning arrester greatly, makes lightning arrester not limited by the use in high height above sea level, heavy pollution area.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, this all insulation composite sheath formula metal oxide arrester mainly is by lightning arrester body 4 and includes exterior parts such as lead-in wire 2, tap grounding screw 5, binding post 1, mounting flange 6 and constitute.Wherein, the upper end of lightning arrester body 4 is crimped with can be for lead-in wire 2 taper sheaths that pass 3, and the lower end of lightning arrester body 4 is connected with described mounting flange 6.Described lead-in wire 2 adopts the High-Voltage Insulation cable conductor, and described binding post 1 is crimped on the upper end of lead-in wire 2, and the lower end of lead-in wire 2 is sealed in the taper sheath 3 and with lightning arrester body 4 upper ends and connects together.The overcoat that one end of tap grounding screw 5 passes lightning arrester body 4 is packaged on the appropriate location of lightning arrester body 4 bottoms, the integral body of go between 2 like this, exterior part such as tap grounding screw 5, binding post 1, mounting flange 6 and lightning arrester body 4 having been formed an all insulation.
Adopt the lightning arrester of this structure; greatly dwindled alternate air distance during installation, as long as binding post 1 is connected on the corresponding phase line of protected equipment, lead-in wire 2 can increase and decrease length according to actual needs during wiring; be convenient to assembling, be particularly useful in the switch cubicle of the confined space.And go between 2 are High-Voltage Insulation cable conductors, and be directly to draw from lightning arrester body 4, thereby improved the creepage distance of lightning arrester greatly, made lightning arrester not limited by the use in high height above sea level, heavy pollution area, made the lightning arrester expansion use high height above sea level, heavy pollution area.
Claims (1)
