Abstract
The invention discloses a generatrix clip for a transformer substation. The generatrix clip is characterized in that wire grooves 1.2 for clamping a generatrix are formed on the two sides of a clip body 1; wire pressing plates 3 for clamping the generatrix are arranged in the wire grooves 1.2; bumps 3.1 matched with grooves 1.1 are arranged on the upper and lower end faces of the wire pressing plates 3; the inner surfaces 3.2 of the wire pressing plates 3 are truncated cone-shaped; two truncated cone-shaped wiring holes 1.3 are reserved on the middle part of the clip body 1; rectangular grooves 1.4 are reserved on the front and rear surfaces of the middle part of the clip body 1; truncated cone-shaped wiring terminals 2.2 are arranged on the horizontal planes of L-shaped down-conductors 2 through screws 2.3; the down-conductors 2 are arranged in the rectangular grooves 1.4 of the clip body 1 through bolts 2.1; and the wiring terminals 2.2 are inserted into the truncated cone-shaped wiring holes 1.3. When the clip is used for equipment, the down-conductors can be disassembled by an insulating operating rod under low potential, hot-line work is facilitated, and the safety running of the equipment is ensured.
Description
Technical field
The invention belongs to electric power power transformation operation technical field, particularly the instrument used of transformer station's hotline maintenance operation.
Background technology
In transformer station's hotline maintenance process, need to employ the bus wire clamp, carry out charged dismounting downlead, every is double-bus, and wire clamp belongs to T-shaped wire clamp, utilizes to be bolted on bus, clamp downlead by U-bolt again, if bolted is not in place or running time is of a specified duration, can cause downlead to come off, directly cause circuit and transformer station's trip accident.Have some problems in disassembly process, after U-bolt is opened, T-shaped wire clamp can misplace, and is difficult to take off downlead, and equipotential personnel must left-right and front-back rock can take off downlead.But the air gap of transformer substation bus equipment is little, and the operating personnel rocks downlead, can cause phase spacing and combined distance inadequate, causes personal injury or equipment breakdown.
Summary of the invention
The problems referred to above that exist in order to solve original substation bus bar wire clamp design a kind of new substation bus bar wire clamp, with assurance equipment and operating personnel's safety, propose following technical scheme.
a kind of substation bus bar wire clamp, its special character is that the both sides of online clamp 1 are provided with the metallic channel 1.2 that the clamping bus is used, be provided with groove 1.1 at metallic channel 1.2 openends, wherein install and clamp the tension disc 3 that bus is used, the both ends of the surface up and down of tension disc 3 are provided with the projection 3.1 that matches with groove 1.1, the inner surface 3.2 of tension disc 3 is that the straight Trail of upper base is large, the little frustum cone side of straight Trail of going to the bottom, have two truncated cone-shaped wiring holes 1.3 above the middle part of online clamp 1, the two sides, front and back at online clamp 1 middle part all has rectangular channel 1.4, by screw 2.3, the truncated cone-shaped binding post 2.2 that Yu Jie Line hole 1.3 matches is installed on the horizontal plane of L-shaped downlead 2, downlead 2 is arranged in the rectangular channel 1.4 of wire clamp body 1 by bolt 2.1, and binding post 2.2 is inserted in truncated cone-shaped wiring hole 1.3.
When using this substation bus bar wire clamp, two buses are placed in respectively in the metallic channel 1.2 of wire clamp body 1 both sides, then tension disc 3 are inserted in the groove 1.2 of metallic channel 1.2 openends.Because the inner surface of tension disc 3 is truncated cone-shaped, namely an end of tension disc 3 is thick, an end is thin, and tension disc 3 is more slotting tighter when inserting groove, therefore can clamp bus.The side of L shaped downlead 2 is rectangular, matches with the rectangular channel 1.4 of wire clamp body 1, is fixed on wire clamp body 1 with bolt 2.1 during installation, therefore can be with downlead securely on hookup wire clamp 1.Because binding post 2.2 and wiring hole 1.3 all are the identical truncated cone-shaped of shape, therefore both contact tightly, reduce contact resistance.But the electrician uses insulating bar earth potential dismounting downlead.
The present invention has following advantage
Use this substation bus bar wire clamp, can charged earth potential dismounting downlead, avoided having improved the equipment reliability of operation because live line working causes the downlead vibration problems.
