Description
Technical field
This utility model relates to electrical equipment technical field, particularly relates to a kind of breaker and switch group and closes the connection of electrical equipment
Locking device.
Background technology
It is used to a deciliter circuit, owing to chopper has arc extinguishing in electrical equipment technical field, chopper and disconnecting switch
Ability but there is no obvious cut-off point, and disconnecting switch does not has arc extinguishing ability but has obvious cut-off point, so when closing circuit,
First close disconnecting switch, be closed again chopper, when breaking circuit, first open chopper, then open disconnecting switch.But in reality
In the operating process of border, there will be error, such as chopper unavoidably undiscovered at closing position, directly disconnecting switch is beaten
Open, owing to disconnecting switch does not has arc extinguishing ability, the strongest electric arc can be caused in the moment that circuit disconnects, cause every disconnecting switch
Even circuit damages, and causes a large amount of damage to property.
Utility model content
The purpose of this utility model is the interlock providing a kind of breaker and switch group to close electrical equipment, it is possible to prevent
Disconnecting switch carries out maloperation in the case of breaker closing, safe and reliable.
For achieving the above object, this utility model adopts the following technical scheme that
A kind of breaker and switch group closes the interlock of electrical equipment, including chopper deciliter instruction rotating shaft and connecting rod, disconnected
The lower end of road device deciliter instruction rotating shaft is arranged at deciliter direction board of chopper, the upper end of chopper deciliter instruction rotating shaft and company
The left end of bar is hinged, and the right-hand member of connecting rod and the lower end of the first connecting lever are hinged, the left end hinge of the upper end of the first connecting lever and the second connecting lever
Connect, and the left end of the left end of the first connecting lever and the second connecting lever be all fixedly installed on-board the circuit breaker, the right-hand member of described second connecting lever with
The upper end handing-over of linkage board, the lower section of linkage board is provided with limiting plate, and limiting plate is fixedly installed disconnecting switch handle.
The instruction rotating shaft of described chopper deciliter uses L-shaped, the right-hand member that chopper deciliter instruction rotating shaft is adopted to be arranged on chopper
Deciliter direction board at, the split-combination transmission gear of middle part and the chopper of chopper deciliter instruction rotating shaft is fixed and is connected, chopper
Deciliter upper end adopted of instruction rotating shaft is hinged with the left end of connecting rod.
A deciliter direction board for described chopper is provided with " dividing " and " conjunction " two flags, and wherein, " conjunction " flag is arranged at
" divide " top of flag.
The axis of described connecting rod is parallel to ground all the time and arranges, and the axis of linkage board is perpendicular to ground all the time and arranges.
This utility model is provided with linkage in deciliter instruction rotating shaft of chopper, prevents disconnecting switch in open circuit
Action under the state of device Guan Bi, safe and reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model when being breaker closing；
Structural representation of the present utility model when Fig. 2 is chopper disconnection.
Detailed description of the invention
As shown in Figures 1 and 2, this utility model includes chopper deciliter instruction rotating shaft 2 and connecting rod 3, and chopper deciliter refers to
Showing that rotating shaft 2 is L-shaped, the middle part of chopper deciliter instruction rotating shaft 2 is fixing with the split-combination transmission gear of chopper to be connected, and chopper divides
The right-hand member closing instruction rotating shaft 2 is arranged at deciliter direction board 1 of chopper；Deciliter direction board 1 of chopper be provided with " dividing " and
" closing " two flags, wherein, " conjunction " flag is arranged at the top of " dividing " flag, and deciliter direction board 1 of chopper is used for
The state of instruction chopper, when the right-hand member of chopper deciliter instruction rotating shaft 2 is parallel to the ground, chopper deciliter instruction rotating shaft 2
Point to " conjunction " flag；The upper end of chopper deciliter instruction rotating shaft 2 is hinged with the left end of connecting rod 3, and the axis of connecting rod 3 is the most parallel
Ground is arranged, and the right-hand member of connecting rod 3 and the lower end of the first connecting lever 4 are hinged, and the upper end of the first connecting lever 4 is solid with the left end of the second connecting lever 5
Fixed connect, and the left end of the upper end of the first connecting lever 4 and the second connecting lever 5 be each attached in disconnecting switch, the right-hand member of the second connecting lever 5 with
The upper end thereof of linkage board 6, the axis of linkage board 6 is perpendicular to ground all the time；The lower section of linkage board 6 is provided with limiting plate 7, spacing
Plate 7 is fixing with disconnecting switch handle 8 to be connected.
When breaker closing, chopper split-combination transmission gear drives chopper deciliter instruction rotating shaft 2 to point to " conjunction " mark
Position, chopper deciliter instruction rotating shaft 2 drivening rod 3 is moved to the left, owing to the upper end of the first connecting lever 4 is fixed in disconnecting switch,
The lower end causing the first connecting lever 4 is moved to the left, so that the right-hand member of the second connecting lever 5 moves down, drives linkage board 6 to moving down
Dynamic, it is stuck in the right side of limiting plate 7, makes limiting plate 7 limited, cause disconnecting switch handle not rotate, so that disconnecting switch
Can not action under breaker closing state.
When breaker open operation, chopper split-combination transmission gear drives chopper deciliter instruction rotating shaft 2 to point to " dividing " mark
Position, chopper deciliter instruction rotating shaft 2 drivening rod 3 moves right, owing to the upper end of the first connecting lever 4 is fixed in disconnecting switch,
The lower end causing the first connecting lever 4 moves right, so that the right-hand member of the second connecting lever 5 moves up, drives limiting plate 6 upwards to move
Dynamic, enable limiting plate to move, so that disconnecting switch can action when breaker open operation.
