Embodiment 1

[0025] see figure 1 and figure 2 , the 110kV and above oil-filled cable terminal accessories of the present invention are used to connect the cable 10 to electrical equipment (not shown in the figure), including at least one crimping liner 20, terminal post 30, stress control body 40, and insulating sleeve Pipe 50, two mounting flanges 60 and a shield 70.

[0026] 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 .

[0027] The crimped liner 20 may consist of one segment or several segments.

[0028] Preferably, the crimping liner 20 is made of a hard metal crimping liner, or a hard polymer material.

[0029] One end of the terminal post 30 is provided with a wiring hole 31 and an optical fiber outlet 32 ​​, and the optical fiber outlet 32 ​​communicates with the wiring hole 31 .

[0030] The cable conductor 11 is sleeved in the wiring hole ...

Embodiment 2

[0038] 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'.

[0039] The 110kV and above oil-filled 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' is led out from one end of the optical fiber sheath 12', and is connected to the terminal When 30 is crimped and connected wi...

Embodiment 3

[0041] 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 of I is the same, which discloses Embodiment 3 of the 110kV and above oil-filled cable terminal accessories of the present invention. This embodiment is similar to Embodiment 1, and the difference is that: the cable conductor 11'' is located in the optical fiber sheath 12 is further provided with a crimping liner 20 ″, and the crimping liner 20 ″ is indirectly located outside the optical fiber 13 .

[0042] The 110kV and above oil-filled 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'' outside the optical fiber sheath 12, and a crimping liner 20'' between the terminal post 30 and When the cable conductor 11'' is crimped and connected, the crimping liner 20 / 20'' bears the crimping force, which prevents the op...

Abstract

The invention discloses a 110KV and above oil-filled cable terminal accessory which comprises at least one compression joint liner tube, a binding post, a stress controller, an insulating sleeve and two mounting flanges; a cable comprises a cable conductor, an optical sheath and at least one optical fiber; a wiring hole is formed in one end of the binding post, and the cable conductor is sleeved inside the wiring hole and is connected with the binding post; the insulating sleeve is sleeved on the binding post, the stress controller and the cable; an insulating filling agent is filled between the insulating sleeve and the cable; the compression joint liner tube is arranged inside the cable conductor and is positioned inside and / or outside the optical fiber sheath; and the optical fiber of the cable goes out from the compression joint liner tube, the optical fiber sheath, the free end of the cable conductor and an optical fiber outlet of the binding post and subsequently goes out from the insulating filling agent. The compression joint liner tube is arranged inside and / or outside the optical fiber sheath of the cable conductor, and when the binding post and the cable conductor are connected, the compression joint liner tube bears compression joint force, so that the optical fiber is prevented from being damaged because of extrusion force, and the lossless join of the optical fiber in the cable is realized.

Description

technical field [0001] The invention relates to a cable terminal accessory, in particular to an oil-filled cable terminal accessory of 110kV and above. 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...
