Detailed Description
The invention is described in further detail below with reference to the drawings and the specific examples.
The network transmission equipment applied to the hydropower station underground powerhouse as shown in fig. 1 to 4 comprises an SDI optical end transmitter 1 and an optical cable car 3 which are positioned in a culvert. The optical cable car 3 comprises a base 3.1, pulleys 3.5 are arranged at two ends of the base 3.1, a pull rod 3.4 is arranged above the base 3.1, the pull rod 3.4 is fixed with the base 3.1 through two oblique support rods 3.2, a protection frame 3.3 parallel to a flange plate 3.6 is arranged at the top of the pull rod 3.4, a flange plate 3.6 is arranged in the middle of the pull rod 3.4, and an optical cable 2 is wound on the flange plate 3.6. The flange 3.6 is provided with a wire hole 3.7 through which the optical cable wire 2 passes. The SDI optical transmitter 1 is arranged at the front end of the flange plate 3.6 and is fixed by an expansion screw.
The receiving end of the SDI optical end transmitter 1 is connected with a data source through a BNC interface. The output end of the SDI optical end transmitter 1 is connected with one end of an optical cable 2 through an SC-SC jumper interface 4, and the other end of the optical cable 2 is connected with an SDI optical end receiver 5 arranged outside the culvert. The number of the SC-SC jumper interfaces 4 is two, and when the equipment is not in use, the front jumper of the optical cable 2 is inserted into the SC-SC jumper interfaces 4, so that pollution and breakage are prevented.
The model numbers of the SDI optical end transmitter 1 and the SDI optical end receiver 5 are yellow OTT1812. The optical cable 2 is a single-mode two-core optical cable with an outer diameter of 1 cm. The SDI optical receiver 5 is connected to the encoder 6 through a BNC interface, and the encoder 6 is connected to the switch 7 through an RJ45 interface.
