Abstract
This utility model is related to a kind of explosive-proof protector shell of high tension cable grounding box sheath protector, and its technical characteristics is：Including hollow rectangular containment vessel body and containment vessel full skirt, hollow rectangular containment vessel body and containment vessel full skirt are made into integration using silicone rubber device, are formed with rectangle perforate at the top of containment vessel body.Silicone rubber device of this utility model using hollow belt full skirt; on the basis of cable run earthing mode is not changed; it is sleeved on outside 3 sheath protectors; the harm that sheath protector blast is caused is solved to equipment and the person; guarantee that personal security, this utility model are applicable to more than 110kV Voltage Cable Lines Constructions.
Description
Technical field
This utility model belongs to high tension cable grounding box technical field, and especially a kind of high tension cable grounding box sheath is protected
The explosive-proof protector shell of shield device.
Background technology
According to power industry standard DL/T401-2002《Directive/guide selected by high tension cable》Regulation, using cable sheath protect
Device is limiting induced voltage and fault overvoltage on power cable metal sheath (or protective metal shell), it is to avoid protective coverings of cable hits
Wear, cause cable metal sheath multipoint earth faults.At present in more than 110kV Voltage Cable Lines Construction earthed systems, except direct
There are sheath protector, sheath protector to lead in other grounding boxes (such as cross interconnected case, mixing grounding box etc.) outside grounding box
Frequently with zinc oxide valve plate as protection location.
When short trouble occurs in cable run, metal sheath can produce very high induced voltage, now sheath protector
Very big Leakage Current can be turned on, easily causes sheath protector to explode.Put in daily shield circulating current live detection and local
During electric live detection, usual sheath protector can be directly exposed in face of testing staff, and sheath protector blast can be to inspection
Survey personnel produce and directly endanger.
Content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of high tension cable grounding box sheath is protected
The explosive-proof protector shell of shield device, solves the harm that sheath protector blast is caused to equipment and the person.
This utility model solves its technical problem and takes technical scheme below to realize：
A kind of explosive-proof protector shell of high tension cable grounding box sheath protector, including hollow rectangular containment vessel body and
Containment vessel full skirt, hollow rectangular containment vessel body and containment vessel full skirt are made into integration using silicone rubber device, containment vessel body
Top be formed with rectangle perforate.
The containment vessel full skirt is three layers and the fabric upper, middle and lower in containment vessel body.
Advantage of the present utility model and good effect are：
Silicone rubber device of this utility model using hollow belt full skirt, on the basis for not changing cable run earthing mode
On, it is sleeved on outside 3 sheath protectors so that sheath protector is enclosed in inside explosive-proof protector shell, and full skirt plays increasing
The effect of strong external insulation, when sheath protector occurs explosion time, explosive-proof protector shell plays cushioning and protection, it is ensured that Ren Yuanan
Entirely, this utility model is applicable to more than 110kV Voltage Cable Lines Constructions.
Description of the drawings
Fig. 1 is structural front view of the present utility model；
Fig. 2 is structure top view of the present utility model；
Fig. 3 is installment state figure of the present utility model；
Wherein, 1- containment vessels body, 2- containment vessel full skirts, 3- rectangle perforates, 4- sheath protectors.
Specific embodiment
This utility model embodiment is further described below in conjunction with accompanying drawing：
A kind of explosive-proof protector shell of high tension cable grounding box sheath protector, as shown in Figures 1 and 2, including hollow length
Square containment vessel body 1 and containment vessel full skirt 2, hollow rectangular containment vessel body and containment vessel full skirt are made into integration, containment vessel
Full skirt is three layers and the fabric upper, middle and lower in containment vessel body, and containment vessel body and containment vessel full skirt adopt silicon
Rubber device is made, and three-layer protection shell full skirt plays a part of to strengthen external insulation, is formed with rectangle and opens at the top of containment vessel body
Hole 3 is connected with the interconnection piece of its upper end for sheath protector.
This utility model is arranged on the lower end of 3 sheath protectors on ground connection busbar first when using；Then will protect
Protective case body hollow space is enclosed within 3 sheath protectors 4, as shown in figure 3, three sheath protectors are surrounded by containment vessel body
Get up, so as to the harm for avoiding sheath protector blast from causing equipment and the person.
It is emphasized that embodiment described in the utility model is illustrative rather than determinate, therefore this reality
With the new embodiment including being not limited to described in specific embodiment, every new according to this practicality by those skilled in the art
The other embodiment that the technical scheme of type draws, also belongs to the scope of this utility model protection.
