Abstract
The invention provides an integrated cable inlet-output sleeve, which comprises an insulated sleeve body made of epoxy resin, wherein three-phase buses are arranged in the sleeve body; the three-phases buses are simultaneously poured in the sleeve body; an inlet hole and an outlet hole are formed in the sleeve body; inner end heads of the three-phases buses extend form the inlet hole and the external end heads of the three-phases buses extend from the outlet hole; the internal end heads are connected with each phase of main loop bus in a switch cabinet respectively and the external end heads are connected with a cable accessory head when the sleeve is installed and used; and an induction coil is arranged in the outlet hole. By application of the integrated cable inlet-output sleeve, three phases of inlet-outlet insulators are integrated, so that the insulated distance between conductors and the width of the switch cabinet are reduced; the risk of air leakage caused by local deformation of the inlet-outlet insulators resulted form the error installation is reduced; the number of sealing rings is reduced; and the sealing reliability is improved.
Description
Technical field
The present invention relates to a kind of cable sleeve that is used for medium voltage switchgear equipment, particularly relate to a kind of incorporate cable turnover thread casing.
Background technology
In the existing at home medium voltage switchgear equipment, every switchgear that has cable turnover line insulator, the cable of each phase turnover line insulator is all independent mutually usually, and each phase cable turnover line insulator respectively adopts a cover sealing ring.Such structure is convenient to install with maintenance and is changed, and single simultaneously volume that only passes in and out the line insulator is also less relatively.
This line insulator that respectively passes in and out is mutually distinguished independent structures, though very ripe technically, there is following problem:
1. each passes in and out the line insulator respectively independently mutually, and the air gap of alternate existence has influenced the raising of phase insulation level, and often the electric pressure along with switchgear raises, and needs to increase the air gap, thereby increases the gas tank width greatly.In today of land resource growing tension, the user presses for the space availability ratio that improves switchgear, and the switchgear size of broad, is difficult to satisfy user's demand in this respect gradually;
Each to pass in and out the line insulator mutually respectively independent, volume is less, when turnover line insulator or cable end are installed improper, unbalance stress, is easy to generate local deformation, causes the air chamber gas leakage, and unnecessary quality accident takes place when causing the switchgear operation;
3. each phase cable turnover line insulator respectively adopts a cover sealing ring, has increased the number of sealing ring, has also increased to seal risk not in place, causes the air chamber gas leakage equally easily, causes the switchgear interruption of service.
Summary of the invention
At the problems referred to above, main purpose of the present invention is to provide a kind of incorporate cable turnover thread casing, it is integrated that three-phase is passed in and out the line insulator, reduce the air chamber width, reduce because the improper risk that line insulator local deformation causes gas leakage that causes passing in and out is installed, reduce the number of sealing ring, improve the reliability of sealing, guarantee the positional accuracy of external end head in the three-phase bus.
The present invention solves above-mentioned technical problem by following technical proposals,
Incorporate cable turnover thread casing, comprise the insulating sleeve body of making by epoxide resin material, be provided with three-phase bus in the sleeve body, three-phase bus is cast in the sleeve body simultaneously, and described sleeve body is provided with incoming line and line outlet, and stretch out from incoming line the inboard termination of three-phase bus, stretch out from line outlet its termination, outside, when installing and using, inboard termination respectively with switch cubicle in each corresponding connection of major loop bus mutually, termination, the outside is connected with the electric cable accessories head.
In one embodiment of the invention, be provided with induction coil in the described line outlet, its effect is to make Electric Field Distribution even, can sense low voltage simultaneously, uses for charged demonstration.
Positive progressive effect of the present invention is that it is integrated that this incorporate cable turnover thread casing passes in and out the line insulator with three-phase, thereby reduces the insulation distance between the conductor, can reduce the switch cubicle width dimensions; Reduced because the improper risk that line insulator local deformation causes gas leakage that causes passing in and out is installed; Reduce the number of sealing ring, improved the reliability of sealing.
