Embodiment 1

[0031] see figure 1 and figure 2 , 110kV and above cable terminal accessories of the present invention relate to oil-filled cable terminal accessories, which are used to connect cables 10 to electrical equipment (not shown in the figure), including at least one crimping liner 20, a connecting piece 30, and a stress control body 40. Insulating sleeve 50, two mounting flanges 60, shielding cover 70, outlet fittings 80, insulator 91 and optical fiber splice box 92.

[0032] The cable 10 includes a cable conductor 11 , an optical fiber sheath 12 disposed in the cable conductor 11 , and at least one optical fiber 13 sheathed in the optical fiber sheath 12 .

[0033] The crimped liner 20 may consist of one segment or several segments.

[0034] Preferably, the crimping liner 20 is made of a hard metal crimping liner, or a hard polymer material.

[0035] One end of the wiring member 30 is provided with a wiring hole 31 and an optical fiber outlet hole 32 , and the optical fiber ou...

Embodiment 2

[0045] see image 3 , image 3 is the enlarged schematic diagram of I', where the position of I' is the same as figure 1 The position at I is the same, which discloses an embodiment in which the crimping liner is arranged inside the cable conductor and outside the fiber sheath. This embodiment is similar to Example 1, the difference being that the crimping liner 20' is set on The cable conductor 11' is located outside the optical fiber jacket 12', and the crimp liner 20' is indirectly located outside the optical fiber 13'. The optical fiber 13' of the cable 10 is led out from one end of the optical fiber sheath 12'.

[0046] The 110kV and above cable terminal accessories of the present invention are equipped with a crimping liner 20' outside the optical fiber sheath 12' of the cable conductor 11', and the optical fiber 13' of the cable 10' comes out from one end of the optical fiber sheath 12' and is drawn out through the optical fiber outlet hole 32. And connected with the...

Embodiment 3

[0048] see Figure 4 , Figure 4 It is the enlarged schematic diagram of I'', where the position of I'' is the same as figure 1 The position at I is the same, which discloses Embodiment 3 of the cable terminal accessories of 110kV and above in the present invention. This embodiment is similar to Embodiment 1, the difference is that: the cable conductor 11'' is located outside the optical fiber sheath 12 further A crimping liner 20 ″ is provided, and the crimping liner 20 ″ is indirectly located outside the optical fiber 13 .

[0049] The 110kV and above cable terminal accessories of the present invention are provided with a crimping liner 20 inside the optical fiber sheath 12 of the cable conductor 11'', and a crimping liner 20'' is set outside the optical fiber sheath 12, and between the connector 30 and the cable conductor 11 When crimping the connection, the crimping liner 20 / 20'' bears the crimping force, which prevents the optical fiber 13 in the crimping liner 20 / 20'' ...

Abstract

The invention discloses a cable terminal attachment with voltage of 110kV and more. The cable terminal attachment is used for connecting cables to electrical equipment, and comprises a crimping liner pipe, a wiring piece, a stress control body and an insulator, wherein a wiring hole is formed in one end of the wiring piece; a cable conductor is sleeved in the wiring hole and is connected with the wiring piece together; the crimping liner pipe is arranged in the cable conductor and is positioned inside and / or outside an optical fiber sheath; the crimping liner pipe is directly or indirectly sleeved outside an optical fiber; and the optical fiber of the cable comes out of the crimping liner pipe or the optical fiber sheath, is led out through an optical fiber lead-out hole and is connected with the optical fiber in the insulator. The crimping liner pipe is arranged inside and / or outside the optical fiber sheath of the cable conductor, when the wiring piece is connected with the cable conductor, the crimping liner pipe bears the crimping force, the optical fiber is prevented from being extruded so as not to be damaged, lossless connection of the optical fiber in the cable is realized, the optical fiber is connected with the optical fiber in the insulator, the creepage distance is increased by introducing the insulator, and the problem that the lead-out length of the optical fiber is large is solved.

Description

technical field [0001] The invention relates to a cable terminal accessory, in particular to a 110kV and above cable terminal accessory. Background technique [0002] In order to solve the overheating problem of 110kV and above cable conductors in traditional cables, an optical fiber is installed outside the cable to measure the temperature of the cable conductors, so as to avoid fire accidents caused by overheating of the cable conductors. [0003] However, the above-mentioned optical fiber is arranged outside and in the middle of the cable with an insulating layer, which makes the measurement inaccurate. In order to measure the heating temperature of the cable conductor more accurately, people adopt the method of directly placing the optical fiber in the cable conductor. However, how to connect the cable with the optical fiber embedded in the cable conductor to the electrical equipment has become an urgent problem in the industry. Contents of the invention [0004] The ...
