Description
Technical field
The utility model relates to electric power facility protector technical field, refers to a kind of cable intermediate joint flexible explosion-proof box especially.
Background technology
Along with improving constantly of urban development planning requirement and industrial automatization, electric energy becomes the major impetus source of present social production life gradually, and the spatter property of electric power energy and high efficiency bring very big convenience.Due to factors such as supply network are huge, electric power system is complicated, power supply link is many, power supply distance is long, the use of power cable and cable tunnel also gets more and more thereupon, cable joint becomes the important splicing point of whole supply network, and its operation stability will directly affect the running quality of electric power system.
Cable intermediate joint, at the scene after installation, runs by surrounding environment influence, inevitably because the external force factors such as moisture intrusion, mechanical stress cause insulation to wreck, causes cable intermediate connector breakdown and explosion accident.Cable joint fire in the cable tunnel that causes of blasting is the most serious power system accident.Because subterranean tunnel narrow space, cable are arranged intensive, thus involved other cables, cause large area blackout, cause irremediable loss to whole electric power system, have a strong impact on power supply reliability.
For these problems; the safeguard measure that power supply unit or unit in charge of construction commonly use be use have fire prevention, waterproof, explosion-proof cable intermediate joint box disposition is carried out to cable intermediate joint; cable intermediate connector Protective fastener is combined in inside housing; once cable intermediate joint generation breakdown and explosion accident; effectively can protect other electric power facilities of periphery under the protection of cable explosion-proof box, prevent the generation of secondary injury.
Cable explosion-proof box conventional is at present metal manufacture or fiberglass manufacture, and product appearance is rectangular column, does not have pliable and tough dilatability.Because cable is that dish contracts or is laid in cable trough or cable shaft, general cable intermediate connector is constructed and is laid and all can cause cable torsional deformation, exactly because cable torsional deformation presents irregular curved state, after causing cable intermediate joint to be constructed, cable explosion-proof box can not the torsional deformation of appropriate cable transition joint, can not effectively cable intermediate joint be fastened in housing, cause cable explosion-proof box cannot install or difficulty is installed.
Therefore, cable explosion-proof box conventional at present just often can only use in the ideal situation, site environment slightly changes, the installation of cable explosion-proof box will be caused to be the devil even cannot install, finally cause the installation abandoning cable explosion-proof box, thus cause the cable intermediate connector of installation to lose due protection, time be engraved in unprotected state under run and threaten the safety of other electric power facilities of periphery and personnel.
Summary of the invention
The utility model proposes a kind of cable intermediate joint flexible explosion-proof box, solve anti-explosion box for cable middle connector in prior art and difficulty is installed, uses the problem that limitation is large.
The technical solution of the utility model is achieved in that
A kind of cable intermediate joint flexible explosion-proof box, comprising: flexible bellow and two explosion-proof end sockets laying respectively at its two ends, and each described explosion-proof end socket is by a upper shield and a lower shield composition; Be fixedly connected with holding screw respectively by flange between described flexible bellow with two explosion-proof end sockets; Described explosion-proof end socket offers filler opening; Protective materials is filled with in described armored cassette.
As preferably, described upper shield and lower shield are semi-cylindrical, and both fasten mutually, and the edge of its junction is screwed connection.
As preferably, described explosion-proof end socket is the explosion-proof end socket that stainless steel is made; Described flexible bellow is the flexible bellow that stainless steel is made.
As preferably, in described filler opening, be provided with the stopple that silicon rubber is made.
As preferably, described protective materials is grail or dry powder fire retardant.
As preferably, the edge that described upper shield and lower shield are interlocked is provided with sealing strip.
Operation principle of the present utility model is as follows:
First the flexible bellow of centre is penetrated cable side, the installation then carrying out cable intermediate joint makes, and after making, is return by flexible bellow and is enclosed within cable intermediate joint position; Again the upper shield of explosion-proof end socket and lower shield are fastened, and be fixedly connected with holding screw by flange with flexible bellow; Fill the protective materials such as grail or dry powder fire retardant by the filler opening be positioned on explosion-proof end socket to armored cassette afterwards, then with stopple, filler opening is clogged.
Armored cassette filler opening and explosion-proof end socket can in the cable between joint when breaking down, in time the high pressure of inside is discharged, the arc light that puncture short can effectively cause by the fire proofings such as inner grail of filling extinguishes in time, thus reach the object of knock down the flame, reduction fault coverage, the safe operation of other cables near ensure that.
The beneficial effects of the utility model are:
By installing flexible bellow additional in the middle of explosion-proof end socket, can realize the bending curvature of armored cassette, efficiently solving the problem that difficulty installed by cable explosion-proof box, the flexural deformation of appropriate cable transition joint, applied widely, bending fitness is high;
Adopt segmented connected mode, convenience quick for installation, assembly are easy to transport and preserve, and protective materials is more easily added in inside;
Bellows has certain flexibility, plays cushioning effect when breaking down, and greatly reduces the impact dynamics of cable intermediate joint explosion time to armored cassette, effectively alleviates explosive forces; Decrease accident rate, ensure that power supply reliability;
The cable of narrow space position is effectively protected, avoids other faults because cable intermediate joint accident causes or injury.
