Description
Technical field
The utility model relates to ultrahigh voltage power equipment technical field, especially a kind of high-voltage alternating current isolating switch main switch knife
The grounding interlocking device of earthing knife-switch is flanked with static contact.
Background technique
In electric power power transmission and transforming equipment, high-voltage alternating current isolating switch is to realize division, conversion line and guarantee interruption maintenance
The important equipment of safety.Disconnecting switch is mainly made of four conductive, insulation, support, transmission parts.High-voltage alternating current isolating switch
It is mainly used to the part that will need to have a power failure in high voltage distribution installation and is reliably isolated with live part, guarantees the peace of service work
Entirely.The mechanical interlocking that the telescopic disconnecting switch of level outdoors only has main switch knife and main switch knife to flank earthing knife-switch for a long time, main switch knife
Not the shortcomings that flanking earthing knife-switch with static contact does not have mechanical interlocking, only leans on electric interlock, and there is poor safety performances.
Summary of the invention
The purpose of the utility model is to provide a kind of structures, and simple, easy for installation, reliable performance high-voltage alternating is kept apart
It closes main switch knife and static contact flanks the grounding interlocking device of earthing knife-switch.
The utility model is realized in this way it includes main switch knife operating stick, interlocking transition seat, interlocking steel pipe, static contact
Flank earthing knife-switch operating stick, user's main switch knife side foundation frame steel pipe, user's static contact side foundation frame steel pipe, interlock plate assembly, interlocking
Disk and interlocking steel pipe, it is characterized in that: main switch knife operating stick is connected by interlocking transition seat with interlocking steel pipe, in interlocking steel pipe
The other end is provided with static contact and flanks earthing knife-switch operating stick, and user's main switch knife side foundation frame steel pipe is arranged under interlocking transition seat
Side, inter-locking panel drive interlock plate assembly, interlocking steel pipe to interlock steel pipe by interlocking transition seat by the small axis of interlock plate fit on
Cooperation.
The utility model is to flank the machine of earthing knife-switch in existing outdoor two column or three column horizontal retractable disconnecting switch main switch knives
On the basis of tool interlocking, increases product main switch knife and static contact flanks the mechanical interlocking of earthing knife-switch.Simple, the installation side with structure
Just, the advantages of reliable performance.
Detailed description of the invention
Fig. 1 is the structural schematic diagram for the interlock that high-voltage alternating current isolating switch main switch knife flanks earthing knife-switch with static contact；
Fig. 2 is main switch knife side main switch knife inter-locking panel partial enlarged view；
Fig. 3 is that static contact flanks earthing knife-switch inter-locking panel partial enlarged view.
Specific embodiment
As shown in Fig. 1-3, which flanks the grounding interlocking device packet of earthing knife-switch with static contact
It includes main switch knife operating stick 1, interlocking transition seat 2, interlocking steel pipe 3, static contact and flanks earthing knife-switch operating stick 4, user's main switch knife side group plinth
Frame steel pipe 5, user's static contact side foundation frame steel pipe 6, interlock plate assembly 7, inter-locking panel 8 and interlocking steel pipe 9, it is characterized in that: main switch
Knife operating stick 1 is connected by interlocking transition seat 2 with interlocking steel pipe 3, and the other end of interlocking steel pipe 3 is provided with static contact and flanks
The lower section of interlocking transition seat 2 is arranged in earthing knife-switch operating stick 4, user's main switch knife side foundation frame steel pipe 5, and inter-locking panel 8 passes through interlock plate
Small axis in assembly 7 drives interlock plate assembly 7, interlocking steel pipe 3 to cooperate by interlocking transition seat 2 and interlocking steel pipe 9.Interlock transition
Seat 2 is made of supporting plate 10, connecting lever plate 11, connecting lever axis 12, U-steel frame 13, U-shaped anchor ear 14, and 5 U-shaped anchor ears 14 consolidate U-steel frame 13
It is scheduled on 6 on user base frame steel pipe, connecting lever 11 and supporting plate 10 is housed on U-steel frame 13, interlocking steel pipe 3 is fixed on supporting plate 10.When
When interlocking steel pipe generation displacement, the supporting plate on 2 connecting lever plates is rotated by the center of circle of 3 connecting lever axis, has the function that transmission displacement.
Its working principle is that: when combined floodgate, 1 main switch knife operating stick drives the assembly of inter-locking panel 8 to carry out 180 ° of divide-shut brake rotations, leads to
The oval slideway for crossing inter-locking panel 8 pulls the small axis in interlock plate assembly 7, and interlock plate assembly 7, interlocking steel pipe 3 is driven to pass through
Displacement is transferred to static contact side inter-locking panel assembly 7 by interlocking transition seat 2, interlocking steel pipe 9, i.e., static contact side interlock plate is assembled 7
On small axis be pulled at the straight mouth of static contact side inter-locking panel 8, so that static contact is flanked earthing knife-switch operating stick 4 and be not able to rotate, reach it is main,
The effect of knife locking.
Based on above, the basic principle of earthing knife-switch interlocking, due to the foundation frame steel between master, earthing knife-switch operating stick there are user
Pipe transmits our products from interlocking the interlocking that steel pipe is directly realized by between main switch knife and static contact by one, herein I
Used interlocking transition seat 2, it effectively by main switch knife (static contact) rotation generate displacement be transferred to static contact (main switch
Knife) side.
