Description
Technical field
The utility model design a kind of high-voltage complete switch equipment more particularly to a kind of XGN high-voltage switch cabinet breaker with
The interlock of operation panel set square.
Background technique
XGN high-tension switch cabinet " five is anti-" interlock is the important measures for guaranteeing electrical equipment and life safety, it is ensured that
The safe operation of switchgear also provides the reliability of high-voltage switch cabinet mechanical interlocking other than strictly pressing guidelines.For
For this cabinet type of XGN, since disconnecting switch does not have disjunction and closes the ability of normal duty electric current, just in case maloperation, because
Disconnecting switch does not have arc-extinction device, will cause arc short-circuit, burns disconnecting switch, and accident is also possible to further expansion, injures people
Body safety.
Nowadays lead between VS1 fixed breaker separating brake interlocking mechanism and the operation panel handle back side in country's XGN switchgear
Cross a connecting rod connection.When operation panel handle is transferred to disjunction locked position of coupler, connecting rod is and then moved, and pulls breaker interlocking machine
Structure, and then depress breaker open operation button linkage mechanism and catch on breaker closing button linkage mechanism (as shown in Figure 1).Due to
The displacement very little of operating handle rotation drive, breaker open operation interlocking mechanism movement range are very big, and directly the two is connected, operates
The displacement of disk handle rotation not can guarantee breaker interlocking mechanism and reach enough strokes, cause to join between breaker and operation panel
It locks and its unreliable.And the two position only is difficult reliably to interlock often close in same level by connecting rod in practice.
Summary of the invention
The utility model is the deficiencies in the prior art to be solved, and provides a kind of XGN high-voltage switch cabinet breaker and operation panel
The interlock of set square.To solve the above problems, the utility model uses following scheme:
A kind of interlock of XGN high-voltage switch cabinet breaker and operation panel set square, including base support, adjustable plate,
Connecting column, draw bar and connecting rod, the base support are equipped with adjustable plate, and the adjustable plate is equipped with connecting column, the connection
Column is equipped with connecting rod, and the connecting rod is equipped with set square, and branch has operation panel on the set square, and the adjustable plate is equipped with traction
Bar, the draw bar other end connection breaker divide casket interlocking gear, and the breaker, which divides, is equipped with open circuit below casket interlocking gear
Device.
Further compared to above scheme, the operation panel is equipped with switching handle.
Further compared to above scheme, the adjustable plate is equipped with several through-holes.
The utility model has the advantages that interlocking mechanism is safe and reliable, at low cost, installation is simple.
Detailed description of the invention
Fig. 1 is the perspective view of the utility model.
Fig. 2 is the left view of the utility model.
Fig. 3 is the rearview of the utility model.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
A kind of interlock of XGN high-voltage switch cabinet breaker and operation panel set square, including base support 1, adjustable plate
2, connecting column 3, draw bar 6 and connecting rod 5, the base support 1 are equipped with adjustable plate 2, and the adjustable plate 2 is equipped with connecting column 3,
The connecting column 3 is equipped with connecting rod 5, and the connecting rod 5 is equipped with set square 7, and branch has operation panel 8, the tune on the set square 7
It saves plate 2 and is equipped with draw bar 6, the adjustable plate 2 is equipped with multiple through-holes 12, and 6 other end of the draw bar connection breaker divides casket
Interlocking gear 10, the breaker, which divides, is equipped with breaker 9 below casket interlocking gear 10.
The operation panel 8 is equipped with switching handle 11, and the switching handle 11 from left to right respectively corresponds maintenance, work and divides
Section three gears of locking, it is operating position when vertical, 45 ° of dextrorotation are that level, which pulls out a little left-handed 45 ° as maintenance position, when operation
It is segmented locked position of coupler, each gear can be positioned voluntarily.When power transmission operates, the switching handle 11 of operation panel 8 is placed in that " segmentation is closed
Lock " position, the set square 7 is depressed the connecting rod and is moved down at this time, stop nut of the connecting column 3 among connecting rod
Adjustable plate 2 is driven to move downward under the action of 4.It pulls draw bar 6 to move downwardly together, and then pulls breaker open operation interlocking machine
Structure 10(breaker closing button linkage mechanism is hooked on, and opening button linkage mechanism is depressed, can not closing operation).It is operating
Insertion switching handle 11, separates earthing switch on disk 8, closes isolation and lower isolation.It can not close a floodgate because breaker 9 is blocked,
This mechanism can reliably prevent on-load operation disconnecting switch.Switching handle 11 is adjusted to the position that " works ", during set square is located at this time
Between position, connecting rod 5 and then move upwards, breaker open operation interlocking mechanism 10 resets under the action of spring itself, so pull
Draw bar 6 and adjustable plate 2 move upwardly together.Because breaker open operation interlocking mechanism 10 sets back, open circuit can be operated at this time
9 division of device.It closes breaker 9 and completes entire power transmission process.
When inspection operation, switching handle 11 is adjusted to " segmentation locking " position, if operator does not shift to an earlier date separating brake breaker, this
When breaker can also pull the direct separating brake breaker of breaker interlocking mechanism because of draw bar 6 and gate-dividing state be kept (can not to close
Lock).The insertion operation handle on operation panel, separately lower isolation and upper isolation, then close earthing switch.Switching handle 11 is adjusted to
" maintenance " position, operation panel 8 is stuck at this time.Set square 7 pulls connecting rod 5 to move upwards, and connecting column 3 and adjustable plate 2 are in connecting rod 5
It is lifted up under the action of tail portion stop nut 4, dragging draw bar 6 moves upwards.Breaker open operation interlocking mechanism 10 its from
It is resetted under 6 double action of body spring and draw bar.Breaker 9 can carry out breaking-closing operating at this time, because operation panel 8 is stuck,
Isolation will not malfunction up and down.It ensure that the safety of service work.
The utility model realizes five anti-requirements of high-tension switch cabinet, and interlocking mechanism is safe and reliable；Mechanism arrangement production letter
It is single, it is at low cost；Due to low in cost, installation is simple, it is easy to accomplish it is anti-to carry out five to XGN high-voltage board in the use of interlocking defect
Transformation.
