Abstract
The invention provides a self-sealing type cable incoming and outgoing device of switch equipment, which is characterized by comprising a conical shell, wherein the bottom of the conical shell is provided with a circular groove clamped on a circular hole on a cabinet shell of the switch equipment, a reinforced spiral band and a spiral tearing band are alternatively wound on the side face of the conical shell, the strength of the spiral tearing band is lower than that of the reinforced spiral band, and one end of the reinforced spiral band is connected with a circular handle arranged on the top of the conical shell. The self-sealing type cable incoming and outgoing device has the advantages of novel principle, reasonable structure, high sealing and protecting performance, suitability to batch production, convenience of use, simplicity of operation and high structural strength, and is favorable for guaranteeing the safety of operators and equipment during maintenance and operation, saving the installation cost of cables, and improving the efficiency and the reliability of cable installation.
Description
Technical field
The present invention relates to a kind of self sealing cable turnover line apparatus of switching device, the protection and the sealing of cable when being used for switching device and passing in and out the shell of line cable through 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 through could connect with switching element behind the cupboard housing, 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, is easy to cause the damage of cable outer protection isolation layer, so seem of crucial importance in the protection of this place's cable; 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 like cable, perforate on turnover line cable protecting device is passed cable more earlier; After installing; With other plugging material unnecessary hole is carried out shutoff again, prevent the inside of the entering switching devices such as steam of toy or dust, humidity, accomplish 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 on turnover line cable unit, to be provided with bottom mount grooves and cable tapping; The bottom mount grooves 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, and toy, dust, steam etc. usually get into switching device inside; Bring very big potential safety hazard for the normal operation of power equipment; So pass the connection of completion of turnover line apparatus and switching element at cable after, with other plugging material unnecessary hole is carried out shutoff, sealing again, accomplishes the assembling of cable.Installation method complex process, the efficient of cable are lower like this, reliability is relatively poor, cost is higher.
Summary of the invention
The self sealing cable turnover line apparatus that the purpose of this invention is to provide a kind of switching device is to solve above-mentioned turnover line cable unit existing problems in the cable installation process.
In order to achieve the above object, the invention provides a kind of self sealing cable turnover line apparatus of switching device, it is characterized in that; Comprise conical shell; The bottom of said conical shell is provided with circular groove, and circular groove is stuck in the circular hole place on the cupboard shell of switching device, and 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 present invention mainly contains following advantage:
1, novel, rational in infrastructure, sealing of principle and protective are high, 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 present invention 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 said 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, and 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.
Conical shell 7 is suppressed through the method for heating injection moulding by the comparatively soft electric insulation rubber of quality and is formed; The outer dia of circular groove 4 is slightly more a little bit smaller than the round hole on the cupboard shell that is located at switching device, and self sealing cable turnover line apparatus can be installed on the cupboard housing of switching device more easily.
When cable is installed; With pulling ring handle 1 and being pulled upwardly; Ring handle 1 can be ined succession and strengthened hurricane band 2 and tear downwards along trochoidal surface from the less spiral tear-strap of intensity 3; According to the size of 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 accomplished; 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.
