Description
Technical field
The present invention relates to a kind of electric equipment, more particularly to a kind of 550kV isolation earthing switch division instruction device.
Background technology
With the sustainable development of China's economy, the demand to electric power continues to increase, usual developed area, the need of electric power
The amount of asking is very big, only relies on local it is difficult to meet electricity needs.Therefore, transmission of electricity turns into a big characteristic of China at a distance.It is domestic
The transregional networking of electric power, be reduce power consumption, using the voltage class of 550kV.The transmission line of electricity of 550kV grades is in conveying energy
During amount, the exception of change is important.Use reliability requirement to each element in combined electrical apparatus inside is high.
Using the pattern of three-phase ganged more than isolation earthing switch in current 550kV combined electrical apparatuses, only wherein one mutually carries
Mechanism, remaining two-phase is observed that the division position of body by link transmission, only mechanism side, when non-mechanism side body occurs
Moving contact division is difficult observation and judges when not in place.Occur three-phase separate closing position it is asynchronous after, easily occur body it is spacing after,
The electrical system of mechanism can not be cut off and cause burn-down of electric motor, body divide-shut brake is not in place can also cause body discharge or virtual connection so as to
Cause body to burn, cause great power transmission and transformation accident.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of 550kV isolation for proposing is grounded
Switch division instruction device.
To achieve these goals, present invention employs following technical scheme：
A kind of 550kV isolation earthing switch division instruction device, including shell and the instruction device located at enclosure, it is described outer
Shell includes the base, middle set, housing and the outstanding frame that are socketed successively, respectively by gluing between the base, middle set, housing and outstanding frame
Agent is fixed；
The instruction device includes power transmission shaft, guide post, indicator, indication dial plate and mechanism rack, the power transmission shaft and finger
Show that device is engaged by screw thread to connect, power transmission shaft is fixed in mechanism rack by bearing；The guide post passes through the endoporus of indicator,
And be fixed in mechanism rack by screw；The indication dial plate is fixed in mechanism rack by screw, and is engaged with indicator；
Mark has point on indication dial plate ", " conjunction " icon, carry out switchback between " dividing ", " conjunction " icon that indicator can be on indication dial plate
Change；When the power transmission shaft is rotated clockwise, indicator is driven to be moved to " dividing " position；When power transmission shaft is rotated counterclockwise, drive refers to
Show that device is moved to " conjunction " position.
Preferably, the power transmission shaft is through shell and extend out to housing exterior.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, shell includes the base, middle set, housing and the outstanding frame that are socketed successively, between the base, middle set, housing and outstanding frame respectively
Fixed by adhesive, make between housing parts be connected it is relatively reliable, it is simple structure, easy to assembly.
2nd, instruction device is engaged as a result of screw thread, the finger of " conjunction " and " dividing " of indicator Linear transmission and indication dial plate
Show mode, can conveniently observe the division indicating positions of isolation earthing switch, it is ensured that the correct status of isolation earthing switch refer to
Show.
Brief description of the drawings
Fig. 1 is a kind of structural representation of 550kV isolation earthing switch division instruction device proposed by the present invention.
In figure：1st, base, 2, middle set, 3, housing, 4, outstanding frame, 5, power transmission shaft, 6, guide post, 7, indicator, 8, dial gauge
Disk, 9, mechanism rack.
Specific embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of embodiment of the invention, rather than whole embodiments.
Reference picture 1, a kind of 550kV isolation earthing switch division instruction device, the division for indicating isolation earthing switch
State, convenient use person observes the division indicating positions of isolation earthing switch, and it includes shell and the instruction located at enclosure
Device, the shell includes the base 1, the middle set 2, housing 3 and outstanding frame 4 that are socketed successively, the base 1, middle set 2, housing 3 and outstanding
Fixed by adhesive respectively between frame 4, make be connected relatively reliable, simple structure, the assembling side between housing parts
Just.
The instruction device includes power transmission shaft 5, guide post 6, indicator 7, indication dial plate 8 and mechanism rack 9, the biography
Moving axis 5 is engaged by screw thread with indicator 7 and is connected, and power transmission shaft 5 is fixed in mechanism rack 9 by bearing；The guide post 6 is passed through
The endoporus of indicator 7, and be fixed in mechanism rack 9 by screw；The indication dial plate 8 is fixed in mechanism rack 9 by screw,
And be engaged with indicator 7；Mark has point on indication dial plate 8 ", " conjunction " icon, indicator 7 can be on indication dial plate 8
Toggled between " dividing ", " conjunction " icon.
When the power transmission shaft 5 is rotated clockwise, indicator 7 is driven to be moved to " dividing " position, when indicator 7 points to dial gauge
During " dividing " position of disk 8, represent that isolation earthing switch assigns to position；When power transmission shaft 5 is rotated counterclockwise, indicator 7 is driven to " conjunction "
Position is moved, and when indicator 7 points to " conjunction " position of indication dial plate 8, represents that isolation earthing switch is closed in place.
Instruction device of the invention as a result of screw thread engage, " conjunction " of the Linear transmission of indicator 7 and indication dial plate 8 and
The indicating mode of " dividing ", can conveniently observe the division indicating positions of isolation earthing switch, it is ensured that isolation earthing switch is just
