Abstract
The utility model provides a self-sealing type cable inlet and outlet device of a switching device, which is characterized by comprising a conical shell, wherein the bottom part of the conical shell is provided with a circular groove, the circular groove is clamped at the position of a circular hole on a shell of a cabinet of the switching device, the side surface of the conical shell is alternated and wound with a strengthening helical belt and a helical tearing belt, the strength of the helical tearing belt is lower than that of the strengthening helical belt, and one end of the strengthening helical belt is connected with a circular ring handle arranged at the top part of the conical shell. The self-sealing type cable inlet and outlet device of the switching device has the following advantages that: the principle is novel, the structure is reasonable, the sealing and protecting property is high, the device is applicable for volume production, the use is convenient, the operation is easy, the strength of the structure is high, the safety of the device and an operator is ensured when the device is overhauled or operated, the installation cost of a cable is saved, and the efficiency and the reliability of installing the cable are improved.
Description
Technical field
The utility model relates to a kind of self sealing cable turnover line apparatus of switching device, and the protection and the sealing of cable when being used for switching device and passing in and out the shell of line cable by switching device when mounted belong to the protection and the technical field of sealing technology of cable.
Background technique
In power transmission and transformation system, switching device is wherein important constituent element, in electric power system, realizing the conveying and the distribution of electric energy, and switching element and other constituent element are to be enclosed in the cupboard housing that switching element is installed, turnover line cable have only by behind the cupboard housing could and switching element connect, fastening, whole like this power equipment could be normal, safety, move reliably.
During the cable hole of turnover line cable on passing the cupboard housing; because of the cupboard housing generally is made by sheet metals such as steel plates; the edge of cable hole is comparatively sharp; be easy to cause the damage of cable outer protection isolation layer; so the protection at this place's cable seems of crucial importance; method commonly used is that the cable tapping at the cupboard housing is provided with turnover line cable protecting device, and the protection isolation layer of cable is protected.In addition; when passing the turnover line apparatus as cable; perforate on turnover line cable protecting device earlier; again cable is passed; after installing; with other plugging material unnecessary hole is carried out shutoff again, prevent that toy or dust, moist steam etc. from entering the inside of switching device, finishes the assembling work of cable.
Turnover line cable unit is to be made by the comparatively soft electric insulation rubber of quality, is easy to like this install and assembling, and is also very favourable to the protection of cable.General making method is to be provided with the bottom groove and cable tapping are installed on turnover line cable unit, the bottom is installed groove and is assemblied on the circular port that is located at the cupboard shell, cable tapping at turnover line cable unit cuts out required perforate with electrician's knife by the size that passes in and out the line outside diameter of cable, so that pass the installation cable, this has just usually produced the problem that another one must solve: the turnover line cable hole that cuts out with electrician's knife is easy to out greatly, toy, dust, steam etc. usually enter switching device inside, bring very big potential safety hazard for the normal operation of power equipment, so after cable passes the turnover line apparatus and finishes connection with switching element, with other plugging material unnecessary hole is carried out shutoff again, the assembling of cable is finished in sealing.Installation method complex process, the efficient of cable are lower like this, reliability is relatively poor, cost is higher.
Summary of the invention
The purpose of this utility model provides a kind of self sealing cable turnover line apparatus of switching device, to solve above-mentioned turnover line cable unit existing problems in the cable installation process.
In order to achieve the above object, the utility model provides a kind of self sealing cable turnover line apparatus of switching device, it is characterized in that, comprise conical shell, the bottom of described conical shell is provided with circular groove, circular groove is stuck in the circular hole place on the cupboard shell of switching device, alternate being wound with in the side of conical shell strengthened hurricane band and spiral tear-strap, the intensity of spiral tear-strap is lower than the reinforcement hurricane band, and an end of strengthening hurricane band is connected at the ring handle at conical shell top.
The utility model mainly contains following advantage:
1, principle novelty, rational in infrastructure, sealing and protective height are suitable for producing in batches;
2, easy to use, simple to operate, structural strength is high, the safety of operator and equipment when having guaranteed maintenance, operation;
3, save the installation cost of cable, improved efficient and reliability that cable is installed.
Description of drawings
Fig. 1 is the plan view of the self sealing cable turnover line apparatus of switching device;
Fig. 2 be among Fig. 1 A-A to sectional view.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 1, be the plan view of the self sealing cable of switching device turnover line apparatus, Fig. 2 is that its A-A is to sectional view.The self sealing cable turnover line apparatus of described switching device comprises conical shell 7, the bottom 5 of described conical shell 7 is provided with circular groove 5, circular groove 5 is stuck in the circular hole place on the cupboard shell of switching device, alternate being wound with in the side of conical shell 7 strengthened hurricane band 2 and spiral tear-strap 3, the intensity of spiral tear-strap 3 is lower than strengthens hurricane band 2, and an end of strengthening hurricane band 2 is connected at the ring handle 1 at conical shell 7 tops.
When cable is installed, with pulling ring handle 1 and being pulled upwardly, ring handle 1 can be ined succession and be strengthened hurricane band 2 and tear downwards along trochoidal surface from the less spiral tear-strap of intensity 3, size according to installation cable outer dia, required perforate when leaving cable and installing, again cable is passed from the circular hole of being torn and and switching element connect; After cable connection is finished, the reinforcement hurricane band 2 of the ring of will ining succession again handle 1 is wrapped in the cable outside along opposite direction when tearing, and bundle, tighten at cable surface after passing draw ring endoporus 6 set on the ring handle 1 with strapping strand, prevent that the reinforcement hurricane band of being torn from unclamping, realized like this this sealing of cable and turnover line apparatus tapping.
