Abstract
The invention discloses a cable terminal for a European-style branch box and a ring main unit. The cable terminal is connected with a cable sleeve which is fixed on a European-style branch box/ a ring main unit in an inserting mode, the cable sleeve comprises a base plate and a bolt arranged on the front of the base plate, the cable terminal comprises a T casing pipe, a cable wiring terminal and an insulation sealing head. The T casing pipe comprises a horizontal casing pipe part and a vertical casing pipe part, wherein the horizontal casing pipe part is communicated with the vertical casing pipe part, the base plate of the cable sleeve is connected with the left side of the horizontal casing pipe part in an inserting mode, the bolt is arranged inside the horizontal casing pipe part, the cable wiring terminal is inserted from a lower end mouth of the vertical casing pipe part and connected with the bolt in a sleeve mode, the insulation sealing head is connected with the right side of the horizontal casing pipe part in an inserting mode and connected with the front end of the bolt in a threaded mode. The cable terminal for the European-style branch box and the ring main unit is simple in structure and convenient to use, facilitates connection between the European-style branch box and the ring main unit and a bypass cable, reduces operation scope, and improves the line power supply reliability.
Description
Technical field
The present invention relates to a kind of cable termination for European feeder pillar, ring main unit.
Background technology
When underground cable needed repairing unusually between two feeder pillars/ring main unit, after taking ground to lay bypass cable and carrying out safety prevention measure, replacing underground cable by bypass cable was the ring main unit power supply, reaches the purpose of (the few power failure) maintenance that do not have a power failure.
At present, the cable sleeve that is positioned at European feeder pillar, ring main unit adopts all insulation, totally-enclosed, hermetic cable termination more, and this cable termination can't separate with the cable that is attached thereto.
When laying the bypass cable operation, because the space in European feeder pillar, looped network cabinet wire hole is less, and the volume of the cable termination that is integrated with bypass cable sealing is larger, can't enter European feeder pillar, ring main unit by entrance hole smoothly, the difficulty that causes bypass cable to be connected with feeder pillar, ring main unit increases, often because of can't implement effective feeder pillar, ring main unit enlarges job area with being connected of bypass cable, make troubles to the service without power-off operation.
Summary of the invention
Purpose of the present invention provides a kind of simple in structure, easy to use exactly in order to address the above problem, can make things convenient for being connected of cable termination and European feeder pillar, ring main unit, be convenient to the service without power-off operation, raising line powering reliability for the cable termination of European feeder pillar, ring main unit.
The object of the present invention is achieved like this:
A kind of cable termination for European feeder pillar, ring main unit of the present invention, this cable termination is plugged on the cable sleeve that is fixed in European feeder pillar/ring main unit, described cable sleeve comprises pedestal and is located at the bolt of pedestal front end, described cable termination comprises T-shaped sleeve pipe, is located at cable connecting terminal and the insulator seal plug of cable end, wherein
Described T-shaped sleeve pipe comprises transverse pipe section and the vertical duct section that is interconnected;
The pedestal of described cable sleeve is plugged in the left side of described transverse pipe section, and described bolt transverse horizontal place described transverse pipe section;
Described cable connecting terminal is inserted and is socketed on the described bolt by the lower port of described vertical duct section;
Described insulator seal plug is plugged in the right side of described transverse pipe section, and the front end of this insulator seal plug and described bolt is spirally connected.
Above-mentioned a kind of cable termination for European feeder pillar, ring main unit, wherein, the end face of described insulator seal plug is provided with the internal thread hole that is complementary with described bolt external screw thread, and the front end of described bolt is rotatably connected in the described internal thread hole.
The present invention makes demountable structure with T-shaped sleeve pipe and cable connecting terminal, during construction, the cable connecting terminal that will be connected with first cable is introduced from the entrance hole of European feeder pillar, ring main unit, again its lower port from T-shaped sleeve pipe vertical duct section is inserted, greatly facilitated cable termination and be connected connection with cable sleeve.
The present invention is simple in structure, easy to use, is convenient to European feeder pillar, ring main unit is connected with bypass cable, has reduced job area, is convenient to the service without power-off operation, improves the line powering reliability.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
See also Fig. 1, cable termination of the present invention is plugged on the cable sleeve that is fixed in European feeder pillar/ring main unit, cable sleeve comprises pedestal 11 and is located at the bolt 12 of pedestal 11 front ends, cable termination of the present invention comprises T-shaped sleeve pipe 2, is located at cable connecting terminal 31 and the insulator seal plug 4 of cable 32, wherein:
T-shaped sleeve pipe 2 comprises transverse pipe section 21 and the vertical duct section 22 that is interconnected, and is square opening 23 at the inner chamber of the intersection of transverse pipe section 21 and vertical duct section 22;
The pedestal 11 of cable sleeve is plugged in the left side of transverse pipe section 21, and bolt 12 transverse horizontal place transverse pipe section 21;
During construction, first will be with the cable 32 of cable connecting terminal 31 from European feeder pillar, introduce in the entrance hole of ring main unit, then its lower port from T-shaped sleeve pipe 2 vertical duct sections 22 is inserted, so that cable connecting terminal 31 is positioned at square opening 23, be plugged on the pedestal 11 of cable sleeve at the left side port with T-shaped sleeve pipe 2 transverse pipe sections 21, so that the bolt 12 of pedestal 11 front ends is set in cable connecting terminal 31 and is positioned at transverse pipe section 21, at last insulator seal plug 4 is plugged in the right side port of transverse pipe section 21, and the front end that makes bolt 12 is rotatably connected in the internal thread hole 41, namely finished thus cable termination of the present invention and European feeder pillar, the connection of ring main unit cable sleeve.
Above embodiment is only for explanation the present invention's, but not limitation of the present invention, person skilled in the relevant technique, in the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
