Carry out at the switchgear assembly scene because the cable deadweight is very large, and being generally at right angle setting in the installation, laid processes of power cable, like this cable reliably fix very importantly, avoid making other parts in equipment stressed because of the gravity of cable; In addition, when cable passes the cupboard shell of switchgear assembly, must seal and protect, in order to avoid the exterior protection layer of cupboard shell damage cable, and carry out necessary sealing, prevent that aqueous vapor, dust, toy etc. from carrying out device interior, causes great security incident.
The general mounting means of power cable of turnover switchgear assembly is: first power cable is passed on the cupboard shell having on protection and the line seal of sealing function after, more separately establish fixture and be fixed firmly, it has following shortcoming:
A) cable is fixed, the sealing of cable and equipment room completes respectively by different structure, and sealing and fixing dependency structure are complicated, complex process.
B) poor, the complex process of the sealing effectiveness of cable;
C) sealing and fixing labour intensity are large, efficient is low, cost is higher;
D) take switchgear effective space larger.
Summary of the invention
The technical problem that the utility model actual needs solves is: the dependency structure that seals between the cable of existing switchgear assembly and equipment, fixes is complicated, complex process; Sealing effectiveness is poor; Sealing and the labour intensity of fixing are large, and efficient is low, and cost is high; The useful space that takies switchgear is large.
The utility model is taked following technical scheme:
A kind of cable incoming-outgoing linear sealing of switchgear assembly, fixture comprise a pair of cable holder 1, and described cable holder 1 comprises center semicircle orifice 101, and semicircle orifice 101 outsides, described center are provided with semicolumn and face the wall and meditate 102; Described a pair of cable holder 1 correspondence is mounted with, and a pair of semicolumn is faced the wall and meditated and respectively is provided with a semiorbicular rubber seal 2 in 102, and described rubber seal 2 clamps cable 3; Described a pair of cable holder 1 is fixedly connected with switchgear assembly wall 4.
Further, described a pair of cable holder 1 is connected with its bolt by the installing hole on switchgear assembly wall 4.
Further, described a pair of cable holder 1 is bolted to connection.
Further, switchgear assembly wall 4 is underside walls of switchgear assembly.
Further, the material of described cable holder 1 is the insulation organic material.
Characteristics of the present utility model are: utilize the cable holder of a pair of annular, and rubber seal, cable is clamped, realize two functions of sealing to the fixing and switchgear assembly wall cable incoming-outgoing mouth of cable.
The beneficial effects of the utility model are:
1, principle is novel, rational in infrastructure, safe and reliable, is suitable for batch production;
2, easy to use, simple to operate, structural strength is high, makes the performance of switchgear assembly more excellent, has guaranteed operating personnel's personal safety and the reliability service of equipment;
3, effectively protect the insulating barrier of power cable, improved reliability of operation;
4, assembling, overhaul efficiency improve greatly, have reduced manufacturing, the installation cost of switchgear.
Therefore, the utility model in the installation process of power cable, provide a kind of easy for installation, barrier propterty good, sealing effectiveness is good, the cable incoming-outgoing wire sealing device of lower-cost switchgear assembly.

Embodiment
Below in conjunction with specific embodiment, the utility model is further illustrated.
Referring to Fig. 1-Fig. 4, a kind of cable incoming-outgoing linear sealing of switchgear assembly, fixture are mainly by a pair of cable holder 1, a pair of rubber seal 2, with, the compositions such as quadruplet fastening bolt, nut, trim pad, bullet pad, fastening bolts etc. mainly play the role of fastening.
Referring to Fig. 1-Fig. 2, the material of cable holder 1 is to be made by the material that has of some strength and rigidity, good insulation preformance by tool, is provided with on cable holder 1 that semicolumn faces the wall and meditates 102, center semicircle orifice 101, the first installing hole 103, the second installing hole 104.
Referring to Fig. 3-Fig. 4, the quality of rubber seal 2 is comparatively soft, and the elastic deformation amount is larger, is very suitable for sealing, insulation and produces clamping force.
Referring to Fig. 1-Fig. 6, first will, a cable holder 1 is fixed on the tapping of switchgear wall 4 by the first installing hole 103 of establishing thereon by fastening bolt, trim pad, bullet pad etc., and a rubber seal 2 is arranged in the groove of semi-cylindrical shape of cable holder 1, cable 3 is passed center semicircle orifice 101, another part rubber seal 2 is arranged in the semi-cylindrical shape groove of another part cable holder 1; Then a pair of cable holder 1 is tightened together by the second installing hole 104 with two cover fastening bolts, second cable holder 1 is fixed on the tapping of switchgear assembly wall 4 by the first installing hole 103 use fastening bolts again, completed whole installation, assembling process.
