Description

Floor type OPGW optical cable residual box in substation

technical field

The utility model relates to a splicing device of a communication optical cable in an electric power system, in particular to a storage box for remaining optical cables used in a substation.

Background technique

The optical fiber composite overhead ground wire (OPGW) is to set the optical fiber composite in the ground wire of the high-voltage transmission line, and form an optical fiber communication network while erecting the transmission line. Optical fiber composite overhead ground wire has the dual functions of ground wire of transmission line, lightning protection and communication transmission. It is an important infrastructure for realizing smart grid. It has been widely used in 35kV ~ 1000kV lines in my country. Different from ordinary overhead ground wires, after the OPGW enters the gantry frame, it must continue to be led down along the frame, and is connected with the ordinary metal-free optical cable entering the communication room to form an optical fiber communication transmission channel. There is no clear and unified standard for laying and installation methods. After most OPGWs enter the station, the remaining fibers and joints of the optical cables are exposed outside. When the final OPGW optical cable is led down from the gantry, the incomplete contact with the metal components of the gantry will cause gap discharge during lightning or grid overvoltage, and the OPGW will be punctured and fused, which will seriously affect the safety of the power system.

Utility model content

The technical problem to be solved by the utility model is to provide a storage box for remaining wires of optical fiber composite overhead ground wires, so as to standardize the laying and installation methods of incoming optical cables and reduce potential safety hazards.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

The floor-standing OPGW fiber optic cable residual box in the substation includes a box body, and box doors are installed on the front and rear sides of the box body, and a fixing frame is installed inside the box body, and an optical fiber box and a wire rack for winding the remaining fiber optic cable are installed on the fixing frame And the fixing card used for fixing the remaining wires of the optical cable, the wires connected to the grounding wires arranged outside the box are connected to the remaining wire frame, and the bottom of the box is provided with installation holes and optical cable inlet and outlet holes.

The further improvement of the utility model is that: the top of the box body is a ridge-shaped top cover, and the surroundings of the ridge-shaped top cover protrude to the outside of the box body to form convex eaves.

The further improvement of the utility model is that: the fixed frame inside the box body is vertically arranged in the middle of the front and rear direction of the box body, and the front and rear sides of the fixed frame are respectively equipped with optical fiber boxes and surplus wire racks; Install a retaining card.

The further improvement of the above technical solution is that: the remaining wire frame is composed of two cross metal frames, the top of the remaining wire frame is provided with a groove for storing optical fibers, and the remaining wire frame is fixed on the fixed frame by bolts.

Owing to having adopted above-mentioned technical scheme, the technical progress that the utility model obtains is:

The utility model can store the remaining wires and joints of the optical cable in the box in an orderly manner, so as to standardize the laying and installation method of the incoming optical cable in the substation and reduce potential safety hazards. The remaining wire frame is composed of a cross intersecting metal frame with grooves at both ends. It is used in conjunction with the fixing card to fix the remaining wires of the optical cable entering and leaving the fiber optic box on the remaining wire frame in an orderly manner. The setting of the ridge-shaped top cover on the top of the box prevents the accumulation of rain, snow and dust, and avoids the damage to the equipment in the box in rainy and snowy weather. The fixing frame is installed in the middle of the box body, and two sets of optical fiber boxes and residual wire racks can be installed on the fixing frame to increase the utilization rate of the box body.
