The security isolation and protection device for the in-station cables of the transformer substation can be installed in the later period, the operation safety and the working efficiency are improved, and by means of the security isolation and protection device (the slidable casing pipes), operation personnel carry out layered protection and isolation on running cables in an in-station cable duct.
Description
Technical field:
The present invention relates to a kind of transformer station optical cable safety isolation protective facility that enters the station.
Background technology:
In transformer station's optical cable raceway groove, optical cable and power cable are gone the same way and are laid, and field work safe exists management risk, and subject study, in conduit line, is accomplished the physical barrier of fire protection flame retarding, and the important optical cable of distinguishing in raceway groove is isolated with the safety in path.Realize transformer station and isolate safely with raceway groove optical cable, meet 18 countermeasures of state's net, eliminate with raceway groove optical cable potential safety hazard.
Transformer station's optical cable safety isolation protective facility that enters the station, main effect is to avoid optical cable in operational process, not to be subject to damage broken outside external force and that relevant construction in later period causes.The installation of safety isolation protective facility all requires to install according to defined after calculating; operating optical cable does not have effectively protection and the isolation to forceful electric power cable; just do not have the effect of its security protection; finally cause the outer damaged wound of optical cable, and telecommunication optical fiber and important protection optical fiber broken string accident occur.
In order to prevent that early stage operating optical cable is subject to the interference of forceful electric power and external force; in walkaround inspection process, in first all stations, optical cable is unguarded checks combing; then will measure statistics to the optical cable of not safety isolation and protection, be all generally that combined circuit power failure and optical cable are transformed the chance establishment officers such as overhaul and carried out surprise and be installed in addition with protective casing measure.But the data of operating backbone optical cable transmission are the significant data links such as protection, scheduling, robotization, information, phone, generally seldom there is the chance of interrupting detecting overhaul.
Summary of the invention:
For overcoming the defect of prior art, the object of the present invention is to provide a kind of transformer station optical cable safety isolation protective facility that enters the station, can install in the later stage, improve processing safety, increase work efficiency, pass through safe isolation facility (slidable cannula), by operating personnel, at station cable ditch, operating optical cable is carried out to layering protection isolation.
Technical solution problem of the present invention adopts following technical scheme:
Transformer station's optical cable safety isolation protective facility that enters the station, described protective equipment comprises two involutory semicircle sleeve pipes, at two edges of the first sleeve pipe along sleeve pipe, be axially respectively equipped with the first slide block and the first chute, at two edges of the second sleeve pipe along sleeve pipe, be axially respectively equipped with equally the second slide block and the second chute, described the first slide block is embedded in described the second chute can be along the endwisely slipping of sleeve pipe, and described the second slide block is embedded in can endwisely slipping along sleeve pipe in described the first chute.
The opening bore of described the first chute is less than the external diameter of described the second slide block, and the opening bore of described the second chute is less than the external diameter of described the first slide block.
Described protective equipment also comprises T-socket, and the inside pipe wall of described T-socket is axially arranged with twice groove along sleeve pipe, and twice groove is in the inside pipe wall setting that is centrosymmetric.
Described protective equipment also comprises L shaped connecting pipe, and the inside pipe wall of described L shaped connecting pipe is provided with twice groove vertically, and twice groove is in the inside pipe wall setting that is centrosymmetric.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, whether the transformer station of the present invention optical cable safety isolation protective facility work of entering the station is not subject to the time and has a power failure to affect, and two semicircle casing pipe sleeves form the pillar of a full circle at the rear fastening in optical cable outside.
2, be applicable to the lightguide cable link operation in all putting into operation in early stage, and strong and weak electricity cable in cable duct is carried out to physical isolation.
3, reduce communication upkeep operation personnel labor intensity, reduce all in transformer station the misoperation rate of workmen to important fibre optic circuits work, the security that has improved station communication fiber optic cable plant.
4, Work tool reduces, and installs simply, and general 110kv 4 people of transformer station all can complete for one day, the several times of can increasing work efficiency.
Accompanying drawing explanation:
Fig. 1 is schematic cross-section of the present invention; Fig. 2 is the connection diagram of the first sleeve pipe and the second sleeve pipe; Fig. 3 is the schematic diagram of T-socket; Fig. 4 is the schematic diagram of L shaped connecting pipe.
Number in the figure: 1 first sleeve pipe, 11 first slide blocks, 12 first chutes, 2 second sleeve pipes, 21 second slide blocks, 22 second chutes, 3 is T-socket, 4 is L shaped connecting pipe.
Below pass through embodiment, and the invention will be further described by reference to the accompanying drawings.
