Photoelectric composite cable connecting device

Abstract

The invention discloses a photoelectric composite cable connecting device. The photoelectric composite cable connecting device comprises: a power cable connector box for electrically connecting a first power cable and a second power cable; and an optical cable connector box for optically connecting a first optical cable and a second optical cable. The optical cable connector box is located outside the housing of the power cable connector box. Connector portions of the first optical cable and the second optical cable are separated from the first power cable and the second power cable respectively in the power cable connector box, and led to the outside from the inside of the power cable connector box for being connected with the optical cable connector box which is located outside the power cable connector box. Thus, compared with the prior art, according to the invention, the size of the power cable connector box does not need to be increased, the manufacturing cost can be reduced, and the interference of the connector portions of the power cables on the connector portions of the optical cables can be reduced, and the detection precision of the optical cables can be improved.

Description

technical field [0001] The invention relates to a connection device of a photoelectric composite cable, in particular to a connection device of a photoelectric composite cable in which an optical cable is wrapped in an outer protective sheath of a power cable. Background technique [0002] At present, power systems at home and abroad have generally used optical fiber to detect the real-time temperature distribution of the entire power cable, and to monitor the operating status of the power cable system in real time, including real-time faults, power cables operating under different loads, ampacity analysis and power cable tunnel fire alarm. Wait. [0003] At the end of the 1990s in China, the optical cable was attached to the power cable to collect data on the operating temperature of the power cable. Obviously, since the power cable and optical cable are separated, external factors (such as airflow, sunlight, etc.) will affect the measurement accuracy, and maintenance is a...

Problems solved by technology

[0010] Most of the optoelectronic composite cable splice boxes currently on the market, for example, the photoelectric composite cable splice boxes disclosed in Chinese patent documents No. In the shell of the box, the size of the shell of the power cable joint box must be increased. Since the shell material of the power cable joint box is generally relatively expensive copper and epoxy glass, the shell size of the power cable joint box increase will inevitably lead to a significant increase in cost, and it is not easy to install and transport. Moreover, placing the optical cable splice box in the housing of a large power cable splice box will also cause the joint part of the power cable to affect the joint part of the optical cable. If it is too large, it will affect the detection accuracy of the optical cable
