Description
Technical field
The utility model is related to a kind of cable accessories, more particularly, to a kind of integrated cable sheath protector.
Background technology
The big section power cables of 35kV and the power cable of 66kV, 110kV and above are single-core cable, electricity
Cable metal sheath one end three-phase is interconnected and is grounded, and the other end is earth-free, when lightning wave or internal overvoltage are flowed along cable core
When, the earth-free end of cable metal sheath will appear higher impulse overvoltage, or when system short-circuit fault current flows through cable
When core, the earth-free end of sheath also will appear very high line-frequency induction overvoltage.Above-mentioned overvoltage may puncture protective coverings of cable
Insulation, causes cable metal sheath multipoint earth faults, and seriously affecting power cable normal operation or even cable is greatly decreased makes
Use the service life.Therefore according to power industry standard DL/T401-2002《High voltage power cable selects directive/guide》Regulation must use cable
Sheath protector is to limit induced voltage and fault overvoltage on power cable metal sheath (or protective metal shell).The prior art
Middle protector both ends are connected using connector, and cable has a certain distance with protector, is connected using conducting wire, and fraction connection needs
It is connected twice, installation is complicated, while not having safeguard procedures.Have again existing protector using big full skirt raising climb electricity away from
From with other functions, take up space big, it has not been convenient to install.
Utility model content
The purpose of this utility model is to provide a kind of integrated cable sheath protector, and cable sheath is protected not will receive height
Pressure impact, while install convenient simple in structure, occupy little space.
To achieve the above object, the utility model provides a kind of integrated cable sheath protector, including ontology, described
Ontology includes insulating sheath, one insulation connection cover, contact electrode, zinc oxide resistance sheet and connector, the one insulation
Connection cover is clamped with the insulating sheath, and the zinc oxide resistance sheet is set between two contact electrodes, the one
Insulation connection cover upper end is provided with connecting line, and described connecting line one end is provided with connecting terminal, and the insulating sheath is provided with ring
Shape protrusion.
Preferably, the connector is connect with the contact electrode thread, between the connector and the contact electrode
It is additionally provided with friction-proof piece, the friction-proof piece is socketed on the connector and is fixed by fixing nut.
Preferably, there are two the fixing nut settings, ground terminal or line bank are set to two fixing nuts
Between, the connector tail end is provided with installation groove.
Preferably, there are three the annular protrusion settings.
Preferably, disconnector can also be connected with below the ontology, the disconnector is heat-explosion type disconnector.
Therefore, a kind of integrated cable sheath protector of the utility model using the above structure, protects cable sheath not
Impacting with high pressure is will receive, install convenient simple in structure is made using one insulation connection cover；Using annular protrusion increase climb electricity away from
From occupied space is reduced simultaneously, it is easily installed.
Below by drawings and examples, the technical solution of the utility model is described in further detail.

Specific implementation mode
Embodiment
Fig. 1 is a kind of integrated cable sheath protector structure chart of the utility model, as shown in Figure 1, a kind of integral type is electric
Cable sheath protector, including ontology, ontology include insulating sheath, one insulation connection cover 2, contact electrode 3, zinc oxide resistance sheet
4 and connector 6, the one connection cover 2 that insulate is clamped with insulating sheath, and the present embodiment zinc oxide resistance sheet 4 is cylindrical type, oxidation
Zinc resistor disc 4 is set between two contact electrodes 3, and 2 upper end of one insulation connection cover is provided with connecting line 21, connecting line 21 1
End is provided with connecting terminal 22, and connecting terminal 22 connect by when installation with the terminals of cable, while one insulate and connects
2 protective higher of lid, improves the service life of protector.Insulating sheath is provided with annular protrusion 1, the present embodiment annular protrusion
There are three 1 settings, compares full skirt and is provided with the creepage distance for occupying little space, while also having reached certain.Connector 6 with contact
Electrode 3 is threadedly coupled, and is additionally provided with friction-proof piece 5 between connector 6 and contact electrode 3, product type and its are carved on friction-proof piece 5
His information, friction-proof piece 5 place the abrasion that 3 shell of touched electrode is docked when being fastened and fixed nut repeatedly.Friction-proof piece 5 is socketed on connector
It is fixed on 6 and by fixing nut.There are two fixing nut settings, ground terminal or line bank be set to two fixing nuts it
Between it is fixed, 6 tail end of connector is provided with installation groove, is tightened by installation groove, convenient and efficient.It can be with below ontology
It is connected with disconnector, disconnector is heat-explosion type disconnector, once puncturing, disconnector is detached from so that staff sends out in time
It now and replaces, improves safety.
Therefore, a kind of integrated cable sheath protector of the utility model using the above structure, protects cable sheath not
Impacting with high pressure is will receive, install convenient simple in structure is made using one insulation connection cover；Using annular protrusion increase climb electricity away from
From occupied space is reduced simultaneously, it is easily installed.
It is specific embodiment of the present utility model above, but the scope of protection of the utility model should not be limited to thoses mentioned above.Appoint
What those skilled in the art is in the technical scope disclosed by the utility model, the change or replacement that can be readily occurred in,
It should be covered within the scope of the utility model, therefore the scope of protection of the utility model should be limited with claims
Subject to fixed protection domain.
