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 of transformer station's live-line maintenance operation.
Background technology
In transformer station's hotline maintenance process, need to employ bus wire clamp, carry out charged dismounting downlead, every is double-bus, and wire clamp belongs to T-shaped wire clamp, utilizes and is bolted on bus, downlead is clamped again by U-bolt, if bolted is not in place or running time is of a specified duration, downlead can be caused to come off, directly cause circuit and transformer station's trip accident.In disassembly process, there is some problems, U-bolt after opening T-shaped wire clamp can misplace, be difficult to take off downlead, equipotential personnel must carry out rocking and can take off downlead by left-right and front-back.But the air gap of transformer substation bus equipment is little, and operating personnel rocks downlead, phase spacing and combined distance can be caused not, cause personal injury or equipment breakdown.
Summary of the invention
In order to solve the problems referred to above that original generatrix clip for transformer substation exists, designing a kind of new generatrix clip for transformer substation, to ensure the safety of equipment and operating personnel, proposing following technical scheme.
A kind of generatrix clip for transformer substation, its special character is the metallic channel 1.2 that the both sides of online clamp 1 are provided with clamping bus, groove 1.1 is provided with at metallic channel 1.2 openend, the tension disc 3 of clamping bus is wherein installed, the both ends of the surface up and down of tension disc 3 are provided with the projection 3.1 matched with groove 1.1, the inner surface 3.2 of tension disc 3 is that the straight Trail of upper base is large, the frustum cone side that the straight Trail that goes to the bottom is little, two truncated cone-shaped wiring holes 1.3 are had above the middle part of online clamp 1, two sides, front and back in the middle part of online clamp 1 all has rectangular channel 1.4, the horizontal plane of L-shaped downlead 2 is provided with by screw 2.3 the truncated cone-shaped binding post 2.2 that Yu Jie Line hole 1.3 matches, 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 generatrix clip for transformer substation, 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 openend.Inner surface due to tension disc 3 is truncated cone-shaped, and namely one end of tension disc 3 is thick, one end is thin, more slotting tighter when tension disc 3 inserts groove, therefore can clamp bus.The side of the downlead 2 of L shape is rectangular, matches with the rectangular channel 1.4 of wire clamp body 1, is fixed on wire clamp body 1 during installation with bolt 2.1, therefore can by downlead securely hookup wire clamp 1.Due to the truncated cone-shaped that binding post 2.2 is all identical in shape with wiring hole 1.3, therefore both contact tightly, reduce contact resistance.Electrician uses insulating bar can earth potential dismounting downlead.
Tool of the present invention has the following advantages
Use this generatrix clip for transformer substation, can charged earth potential dismounting downlead, avoid because live line working causes downlead vibration problems, improve equipment reliability of operation.
