Combined using method for optical cable and mine cable and mine cable as fiber-optical communication

Abstract

The invention provides a combined using method for an optical cable and a mine cable and the mine cable used as fiber optical communication, which is to arrange the optical fiber in the mine cable to ensure that the optical fiber and the cable are combined to a whole to form the mine cable used as fiber optical communication. In a connecting line cavity of explosion-proof type electrical equipment of high voltage feed switch, a low voltage feed switch, an electromagnetic initiator and the like, the end of the optical cable is manufactured into a pigtail and is connected with an optical interface of an optical transmitter and receiver through an optical fiber connector and a jumper; the optical transmitter and the receiver is connected with an intelligent integrated protective device in a main cavity through a communication interface; the jumper and the optical transmitter and receiver are connected through an optical cable explosion-proof cavity connection device, or are connected through wiring terminals on a separator of two cavities; and non-disconnected connection of non explosion proof equipment and the explosion proof high voltage equipment can adopt an optical fiber connector. The optical cable and the cable are combined into a whole without impacting fracture and insulation of the cable, so that the underground optical cable applying range is the same as that of cablesto solve the problem of optical fiber communication between electric equipment; and the method saves cost because the optical cable is not required to be applied independently, so that the underground power supply and fiber-optical communication can be organically combined.

Description

technical field [0001] The invention relates to the field of underground power supply and optical fiber communication in coal mines, in particular to a combined use method of optical cable and mine cable which is suitable for the underground environment of coal mines with explosive dangerous gas and coal dust and organically combines optical cable communication with mine power supply and its double function Mining cables for optical fiber communication. [0002] Background technique [0003] With the advancement of technology, optical fiber communication has been rapidly developed and popularized. However, the application in underground coal mines is relatively limited. The reason is that due to the particularity of underground coal mines—environment with explosive and dangerous gas and coal dust, the laying and connection of optical cables, especially the conversion of optical signals and electrical signals are restricted by explosion protection, making it impossible for t...
