Abstract
The utility model discloses a disconnectable grounding type optical cable cross-connecting box, which enables grounding of an OPGW optical cable leading-in and cross-connecting device to adopt a mode of disconnectable connection. The disconnectable grounding type optical cable cross-connecting box at least comprises a box body, a residual cable rack and a joint box, wherein the box body is made of an insulating material, the residual cable rack and the joint box are arranged in the box body, the box body is internally provided with a special grounding tandem block used for grounding of the OPGW, the residual cable rack and the like. The box wall is provided with a grounding leading-out terminal, and the inner side is connected with the grounding tandem block. The grounding leading-out terminal is connected with a transformer substation grounding grid through a grounding down lead. The grounding leading-out terminal is connected with the grounding down lead by adopting a disconnecting and connecting clamp, thereby being convenient for disconnecting. The disconnectable grounding type optical cable cross-connecting box has the characteristics of convenient use, safety, reliability, and simple structure, and can meet practical and technical requirements.
Description
Technical field
The utility model relates to a kind of OPGW introducing, connection device, but especially a kind of connection device that makes the ground connection employing breakaway-element connection of OPGW leading-in end.
Background technology
Along with the widespread use of electric system composite ground wire optical cable (OPGW), transformer station needs a large amount of OPGW introducing, connection device.At present introducing mode commonly used be with connector box 2., 3. remaining cable frame be arranged on the outlet structure of transformer station, as accompanying drawing 1.Also have with connector box 2., 3. remaining cable frame be arranged in the metal box that lands, shown in accompanying drawing 2.
There is subject matter in present mounting means: due to connector box 2., remaining cable frame 3. or casing be connected by framework or basis and grounding body in transformer station, when needs are measured substation grounding resistance, can not thoroughly disconnect OPGW ground connection in transformer station, affect the accurate measurement of substation grounding resistance.
Summary of the invention
The fiber cable cross connection box that the utility model provides a kind of and 5. OPGW can be introduced, but the ground connection of connection device adopts breakaway-element to connect.Overcome above-mentioned shortcoming.
The utility model is completed by following technical solution, which comprises at least the casing made by insulating material 1. with casing the cable splice closure in 1. 2., remaining cable frame 3., arrange in casing special-purpose ground connection tandem row 4. be used for OPGW 5., the remaining cable frame ground connection of 3. waiting.The ground connection leading-out terminal is set 6. on tank wall, 4. ground connection leading-out terminal inboard 6. is connected with ground connection tandem row, and the outside is for joining with grounding net of transformer substation.The outside adopts breaking of contact 7. to be connected with down conductor, is convenient to disconnect.5. OPGW wears insulation tube and 8. enters in this cross-connecting box, and 9. the insulation tube outer steel pipe is protected.
The utility model is a kind of improvement to prior art, solved the problem of " when needs are measured substation grounding resistance; can not thoroughly disconnect OPGW ground connection in transformer station; affect the accurate measurement of substation grounding resistance " of present existence, have characteristics esy to use, safe and reliable, simple in structure, can satisfy the requirement of practical and technique.
Description of drawings
Fig. 1 is traditional cable splice closure and remaining cable frame mounting means.
Fig. 2 is conventional metal optical cable cross-connecting box.
Fig. 3 is the grounding type fiber cable cross connection box structural representation that breaks of the present invention.
Fig. 4 is the grounding type fiber cable cross connection box mounting design schematic diagram that breaks of the present invention.
Embodiment
As shown in Figure 4, the utility model comprise at least the casing made by insulating material 1. with casing in cable splice closure 2., remaining cable frame 3..4. casing arranges ground connection tandem row in 1., be used for OPGW 5., the remaining cable frame ground connection of 3. waiting.The ground connection leading-out terminal is set 6. on tank wall, 4. ground connection leading-out terminal inboard 6. is connected with ground connection tandem row, and 7. the outside joins with grounding net of transformer substation by breaking of contact.Described casing 1. hanging is installed on the wall or on vertical surface-based basis.
The below is an embodiment of the present utility model, but embodiment of the present utility model is not limited to this.5. OPGW draws from outlet structure and wears insulation tube after lower and 8. enter in this cross-connecting box, and 9. 8. insulation tube protected with steel pipe.5. OPGW enters this cross-connecting box, first 3. goes up coil at remaining cable frame, then causes connector box 2..Stand in metal free optical fiber cable connector box 2. in and 5. welding of OPGW, 3. be connected to machine room after coil through remaining cable frame.OPGW metal part is 5. arranged with the ground connection tandem in case and 4. is connected.7. the ground connection leading-out terminal 6. outside is connected by breaking of contact with down conductor.5. OPGW keeps only having the framework top some to be connected with framework, and framework middle part employing insulating support is OPGW fixedly.
When measuring the stake resistance of transformer station, as long as remove breaking of contact that 6. the ground connection leading-out terminal go up 7. with framework on the grounding connection terminal, 5. OPGW is disconnected fully with substation grounding, eliminate the impact on the substation grounding resistance measurement because of OPGW outside transformer station, steel tower ground connection.Transformer station's main grounding grid resistance measurement is complete, answers the ground connection of immediate recovery cross-connecting box and outlet structure.
Claims (3)
1. grounding type fiber cable cross connection box that can break is characterized in that casing made by insulating material, installing ground connection leading-out terminal on tank wall, and in cross-connecting box, OPGW, remaining cable frame etc. need the part of ground connection all by the ground connection leading-out terminal ground connection on tank wall.
2. the grounding type fiber cable cross connection box that breaks according to claim 1, is characterized in that OPGW cover insulation pipe enters in this cross-connecting box, and the insulation tube outer steel pipe is protected.
3. the grounding type fiber cable cross connection box that breaks according to claim 1, is characterized in that the ground connection leading-out terminal on tank wall is connected with down conductor by dismountable breaking of contact.
