Example Embodiment

[0047] Example 1:

[0048] A protective device for the bare ground of a cable, including a protective shell. The protective shell includes a paired outer end protective shell 4 and a paired middle protective shell 5. Line cavity, the middle protective shell 5 is set at one end of the outer protective shell 4 and is movably connected to it. The outer protective shell 4 is set on the cable sheath at the outer end of the bare cable ground when in use. Cover the bare ground of the cable. Wherein, there may be one outer protective shell 4 of the outer aligning type, the middle protective shell is arranged at one end thereof, or two, and the middle protective shell is arranged between the outer protective shells. The outer end protective shell 4 includes two or more outer end sub-shells, a pair of adjacent two outer end sub-shells are hinged on the sides, and the corresponding pairs form two outer end sub-shells of a circular cavity. The sides are movably connected by a buckle / buttin...

Example Embodiment

[0050] Example 2:

[0051] On the basis of Embodiment 1, this embodiment has made the following improvements:

[0052] An automatic spring-opening device for the middle sub-shell, such as a torsion spring mechanism 12, is provided at the hinged joint between the middle sub-shell and the outer end protective casing 4 of a protective device for the bare grounding of the cable.

[0053] An automatic spring-opening device for the middle sub-shell, such as a torsion spring mechanism 12, is provided at the hinged joint between the middle sub-shell and the outer protective casing 4 of a waterproof and moisture-proof processing mechanism used for the bare grounding of the cable.

[0054] When grounding is required for maintenance, the difference from Embodiment 1 is that after opening the locking shell 8, the middle sub-shell automatically pops open, exposing the metal foil wrapped around the grounding part, and then the grounding wire can be used. Clasp to open the shell 10.

Example Embodiment

[0055] Example 3:

[0056] On the basis of Embodiment 2, this embodiment has made the following improvements:

[0057] A locking device for a protective device for the bare ground of a cable is changed to include two locking half shells 13, which are movably connected, and the inner diameter of the cavity formed by the coincidence is the same as that of the middle protective shell 5. The outer diameter matches. One end of the locking device is arranged on the outer periphery of the outer protective shell 4, and the other end is arranged on the outer periphery of the middle protective shell 5. At least one locking half shell 13 is provided with a first baffle 16 on the inner side close to the middle protective shell 5. 16 The inner arc is matched with the outer diameter of the outer end protective shell 4, the outer end protective shell 4 is provided with a limiting baffle 15, and a compression spring 14 is provided on the outside of the outer protective shell, corresponding to the...

Abstract

The invention discloses a protective device used for a cable ground exposing position. The protective device comprises a protective outer shell which comprises an opposite-matched type outer end protective outer shell and a middle protective outer shell. The middle protective outer shell is arranged at one end of the outer end protective outer shell and is movably connected with the outer end protective outer shell. The invention further discloses a waterproof and humidity-proof processing mechanism used for the cable ground exposing position. The waterproof and humidity-proof processing mechanism comprises a roll of split-type metal foil which is wrapped on the cable ground exposing position and extends to a cable protective sleeve outside the cable ground exposing position when used. A protective outer shell is arranged on the periphery of the metal foil. The structure and using of the protective outer shell are identical with those of the protective device. The waterproof and humidity-proof processing mechanism protects the cable ground exposing position, has the advantages of being waterproof, humidity-proof, anti-oxidant, good in safety, strong in generality and capable of enabling ground connecting to be convenient and rapid, effectively prevent the cable from being corroded, prolong service life and improving electricity transmitting efficiency.

Description

technical field [0001] The invention relates to the technical field of electric power supply, in particular to a protection device and a waterproof and moisture-proof treatment mechanism for the exposed grounding of cables. Background technique [0002] It is very important to ensure the safe and stable operation of the power grid. If the cable connection is not properly handled, it will bring a lot of troubles to people's production and life, and even pose a safety hazard. Existing cables with sheaths are only treated with simple waterproof and moisture-proof treatment at the junction, such as the commonly used electrical tape, which will become hard and brittle at low temperatures and soft at high temperatures. Affected by thermal expansion and contraction, it is not only waterproof , The moisture-proof effect is not good, and because the electrical tape will age after being used for a long time, the wiring part of the cable is easy to corrode, which affects its conductivi...
