Abstract
The utility model discloses a kind of special-shaped high-voltage wall bushing, this sleeve pipe comprises conduction connector and outer insulator, this outer insulator is with installed part, described conduction connector one end structure with bolts, the other end adopts screw syndeton, the length that described outer insulator covers conduction connector exceedes the position of conduction connector both ends of the surface, for conduction connector be hidden in outer insulator avoid alternate electric discharge, short circuit and installation or maintenance time human body contact conduction connector.Can live line working and be applicable to the different situation of wall both sides power line terminals structure when the utility model uses.
Description
Technical field
The utility model relates to a kind of power line connector, particularly relates to a kind of power line special-shaped high-voltage wall bushing connecting use through walls.
Background technology
the high-voltage wall bushing of power line use through walls is a kind of component that power industry is commonly used, such as power line turnover transformer station or power distribution station, high-voltage wall bushing by power line use through walls is passed through wall, makes the isolation of the indoor of transformer station or power distribution station and outdoor effective and safe.As shown in Figure 1, each power line under bus B will through body of wall C enter into indoor with will by the high-voltage wall bushing A of power line use through walls to each equipment during each equipment connection, the high-voltage wall bushing A of power line use through walls can make insulation between power line and body of wall good, can not discharge, leaks electricity to wall.Power line will enter in cabinet through Electric Appliance Cabinet dividing plate for another example, power line is installed to cable branch box, and also has dividing plate in case, all can use the high-voltage wall bushing of power line use through walls in these situations.
How does the high-voltage wall bushing of so existing power line use through walls connect each power line? first we look at the structure of the high-voltage wall bushing of existing power line use through walls, see the high-voltage wall bushing of kind of the power line of two shown in Fig. 2 and Fig. 3 use through walls, their outside is insulator, centre is a metallic conductor, and the connector at electric conductor two ends is all outside exposed.Some is different for its electric conductor shape of the high-voltage wall bushing of kind of the power line of two shown in Fig. 2 and Fig. 3 use through walls, a kind of shown in Fig. 2 is screw, directly firmly be connected with power line by nut, or power line adopts the power line of band screw terminal to connect; Electric conductor shown in Fig. 3 is sheet, and power line is directly fixed on the electric conductor of sheet by screw bolt and nut.Its bolt of this wall bushing of Fig. 2 is outside exposed obviously, can be directly firmly connected with power line by nut, manual operation must have a power failure, otherwise cannot carry out, also its screw rod can be utilized to be connected with the power line of band screw terminal, but use when the power line terminals structure on wall both sides is different limited, also easily get an electric shock simultaneously, during operation, also want power failure operation.This wall bushing of Fig. 3 display, clearly necessary power failure operation, and inconvenient operation.When how to allow wall bushing use, adaptability is stronger and can live line working be current problem demanding prompt solution.
Utility model content
The purpose of this utility model is to provide the live line working of a kind of energy and the different in nature high-voltage wall bushing being applicable to wall both sides power line terminals structure different situations.
This special-shaped high-voltage wall bushing that the utility model provides comprises conduction connector and outer insulator, this outer insulator is with installed part, described outer insulator and conduction connector are closely connected as a single entity, the length of outer insulator at least will exceed conduction connector two ends to be enough at formation end, two ends arc control device, described conduction connector one end structural sections with bolts, the other end adopts screw syndeton section.
In order to improve arc quenching effect further, the internal diameter of described outer insulator is greater than the external diameter of the bolt of described bolt fastening structure section, and forms sidepiece arc control device with bolt side.Outer insulator adopts hard insulation or adopts synthetic insulating material to make.
In order to ensure that the utility model uses the screw thread at front conduction connector two ends to stand intact and keeps clean dry, there are sealing ring and capping in described conduction connector two ends.
The utility model is hidden in outer insulator due to conduction connector, and conduction connector one end adopts screw syndeton, other end structure with bolts, when can avoid during use installing or keeping in repair, human body contacts conduction connector, thus realize live line working, during especially for three-phase power power supply, because phase spacing is narrow, easily have electric discharge, short circuit phenomenon, and the utility model just can avoid alternate electric discharge, short circuit.The utility model is used to be most suitable when wall both sides power line terminals structure is different.
Accompanying drawing explanation

Reference numeral:
Conduction connector 1, outer insulator 2, installed part 3, installing hole 4, end arc control device 5, sidepiece arc control device 6, bolt fastening structure section 11, screw syndeton section 12.
Embodiment
The utility model has conduction connector 1, outer insulator 2, installed part 3, installing hole 4 as can be seen from Figure 4, outer insulator 2 is longer than conduction connector 1, and be enough to form arc control device 5 in end, conduction connector 1 is made to be hidden in outer insulator 2 on the one hand, workman can not contact conduction connector, the arc control device that when the utility model is connected with external piece on the other hand, self-assembling formation is airtight, can ensure the safety of live line working.The two ends section of conduction connector 1, one section is bolt fastening structure section 11, and another section is screw syndeton section 12.At bolt fastening structure section 11 place, the internal diameter of outer insulator 2 is greater than the external diameter of the bolt of bolt fastening structure section, make outer insulator 2 form sidepiece arc control device 6 with the side of bolt, the spark produced when external power line terminals is connected with conduction connector can extinguish rapidly, very safe.In order to economize on material to greatest extent, ensure that bolt fastening structure section has enough external spaces and arc extinguishing space, outer insulator 2 is one large one small, large by bolt fastening structure section, little by screw syndeton section simultaneously.
General rigid insulation body can be adopted as porcelain insulator if the utility model is used in indoor outer insulator 2, if be used in outdoor can use synthetic insulating material.In addition should there be sealing ring 7 and capping 8 in the two ends of conduction connector to protect the screw thread at conduction connector two ends, make it to stand intact and clean drying.When the utility model uses, first capping 8 is opened, sealing ring 8 is motionless, keep and connect the use of external electric power line, by the utility model through body of wall (or steel plate), make bolt fastening structure section 11 and screw syndeton section 12 respectively on the both sides of body of wall, then installed part is close to wall, by installing hole 4, this product is fixed on body of wall.Note not anti-loaded, bolt fastening structure section 11 should be corresponding with the terminal of power line with screw syndeton section 12.Just the power line on body of wall both sides can be twisted after this product fixes and tap into.Whole process can live line working, very safe.
