Description
Technical field
The utility model belongs to electric power facility protective device technical field, and in particular to a kind of arc of cable intermediate joint
Armored cassette.
Background technique
As urban is built, many power cables all sink to butt joint in cable duct, to cancel on street
Cable butt connecting box, bring some potential safety problems to other cables operation of cable duct, be whole cable fortune at cable butting
Capable weakness once explodes at cable butting, often leads to electrical fire, surrounding adjacent cable is also destroyed, is made
At fault spread, irremediable loss is caused to entire electric system.To avoid occurring at cable butting breakdown and explosion to phase
Adjacent cable damages, and installing additional at cable butting has explosion-proof, fire-proof function anti-explosion box for cable middle connector, can be maximum
The reduction causality loss of limit avoids electrical fire, prevents second accident.But docking among the cable in city cable pipe trench
All be not after head docking molding it is straight, some cable connectors can be with the curved shape of cable at arc shape, using straight anti-
Quick-fried box be easy to cause armored cassette poorly sealed, to not have explosion-proof effect.
Utility model content
To solve the above problems, the purpose of the utility model is to provide a kind of arc armored cassettes of cable intermediate joint.
A kind of arc armored cassette of cable intermediate joint, including outer arc lid and inner arc lid, the outer arc lid and inner arc lid side
Side is equipped with engaging lug, and the engaging lug is equipped with several fixation holes penetrated for connecting screw, the outer arc lid and inner arc lid
Both ends are equipped with the cable port that current supply cable passes through, and the outer arc is covered equipped with pressure relief opening, filled between the outer arc lid and inner arc lid
There is quartz sand.
Further, the radian of the outer arc lid is 110 °, and the radian of the inner arc lid is 85 °.
For guarantee the explosion-proof of armored cassette, waterproof, fire protecting performance, the material of the outer arc lid and inner arc lid is that glass reinforced plastic is multiple
Condensation material.
The arc armored cassette of the utility model cable intermediate joint, compared with prior art, the beneficial effect is that: 1.
Utility model can be used at the cable connector on non-rectilinear, and waterproof, explosion-proof, fire prevention, electrical insulation capability are good, corrosion-resistant；2. reality
Electric arc luminous energy is converted to thermal energy, can completely cut off arc energy in box, and pass through box body by the effect that arc extinguishing is effectively played with New Energy
On the discharge of pressure relief opening slowing down heat energy, not impact injury adjacent cable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the arc armored cassette of the utility model cable intermediate joint.
As shown in the figure, 1- outer arc lid, 2- inner arc lid, 3- connecting screw, 4- engaging lug, 5- pressure relief opening, 6- cable port.
Specific embodiment
The principles of the present invention and feature are described with reference to embodiments, illustrated embodiment is served only for explaining this
Utility model is not intended to limit the scope of the utility model.
As shown in Figure 1, a kind of arc armored cassette of cable intermediate joint, including outer arc lid 1 and inner arc lid 2, the outer arc
Lid 1 and 2 side of inner arc lid are equipped with engaging lug 4, and the engaging lug 4 is equipped with several fixation holes penetrated for connecting screw 3, described
The both ends of outer arc lid 1 and inner arc lid 2 are equipped with the cable port 6 that current supply cable passes through, and the outer arc lid 1 is equipped with pressure relief opening 5, described outer
Quartz sand is filled between arc lid 1 and inner arc lid 2.
Further, the radian of the outer arc lid 1 is 110 °, and the radian of the inner arc lid 2 is 85 °.
To guarantee the explosion-proof of armored cassette, waterproof, fire protecting performance, the material of the outer arc lid 1 and inner arc lid 2 is glass reinforced plastic
Composite material.
When using the utility model, after cable butting is got well, it is placed on inner arc lid 2, and cover outer arc lid 1, with connection
Screw 3 connects outer arc lid 1 and inner arc lid 2, that is, forms explosion-proof cavity, and upper quartz sand is filled in explosion-proof cavity and is
It can.
The outer arc lid of the utility model, engaging lug and cable port are integrally formed, inner arc lid, engaging lug and cable port one at
Type, and glass fiber reinforced plastics composite material is used, corrosion-resistant, explosion-proof, waterproof, fire prevention, electrical insulation capability are good, it can soak for a long time, Bu Huiyin
Moist and shape and explosion-proof performance is caused to change, the service life is long.
It is 50-400mm that the utility model, which is suitable for nominal section,2High and low pressure power cable and crosslinked polyethylene electric power
The intermediate butt joint of cable cold (heat) contracting, can use under the conditions ofs cable duct, well and direct-burried etc., applied widely.
The protection scope of the utility model is not limited to technical solution disclosed in specific embodiment, all practical according to this
Novel technical spirit any modification, equivalent substitution, improvement and etc. to the above embodiments, each fall within the guarantor of the utility model
Protect range.
