Description
Technical field
The present invention relates to high voltage electric equipment field, particularly a kind of high-voltage switch gear.
Background technology
Application number CN201510105124.0 Chinese invention patent application discloses a kind of high-voltage switch gear, and this kind of height presses off
Pass includes first switch and second switch, and the operating mechanism of high-voltage switch gear includes with operation handle to be connected and can be in manipulator
The drive shaft that is rotated under the driving force effect of handle, set rotate on the driving shaft and with the rotation of drive shaft driving connecting lever,
Driving connecting lever includes the first driving connecting lever and the second driving connecting lever.
The operating mechanism also includes the rotary shaft being connected with first switch and the middle rotating shaft for being provided with connection pivoted arm, rotary shaft
First switch is driven to act during rotation, in the first angle of drive shaft turns, connection pivoted arm is connected with the first driving connecting lever, is driven
Axle drives connection pivoted arm to rotate；And outside first angle, connection pivoted arm and the first driving connecting lever disengagement, the drive shaft not company of drive
Switch through arm rotation；Drive link of the rotary shaft with being connected pivoted arm is connected, promotes rotary shaft to rotate when connecting pivoted arm and rotating.Wherein
Two driving connecting levers, which are provided with, allows bit architecture, and when drive shaft rotates in first angle, the second driving connecting lever does not drive second to open
Pass acts, and when beyond drive shaft is in first angle, the second driving connecting lever drives second switch action.In this kind of high-voltage switch gear
Operating mechanism the operation splitting successively of first switch and second switch is realized using a drive shaft.
The problem of existing high-voltage switch gear is present is, although realizing two by the time difference and differential seat angle of single drive shaft
Or the switching action of multiple switch, but the Unpredictability between complication due to operating procedure and operating mechanism and switch,
Single shaft operation but increases understanding difficulty of the operating personnel to operating method and improves operating personnel to operation in practical operation
The suspicious degree of correctness.
Under the premise of herein, the folding need of work that some parties in request then require each to switch in switch is by individually operating mould
Block is carried out.
The content of the invention
The purpose of this utility model is to provide a kind of while has disconnecting switch, vacuum switch and an earthed switch and often
Individual high-voltage switch gear of the switch with independent operation.
High-voltage switch gear provided by the utility model include frame and be arranged in frame disconnecting switch, vacuum switch with
And folding is realized in earthed switch, swing of the disconnecting switch by isolating swing arm, vacuum switch is opened by the mobile realization of moving contact
Close, folding is realized in swing of the earthed switch by being grounded lock.High-voltage switch gear also includes the operating mechanism being arranged in frame, actuating
Mechanism includes the first input shaft, the second input shaft and the 3rd input shaft, and the first input shaft and the 3rd input shaft are parallel to each other；First
Input shaft is linked first rotating shaft by first connecting rod mechanism, first rotating shaft linkage second connecting rod mechanism, second connecting rod mechanism it is defeated
Go out end for isolation swing arm；Second input shaft linkage third connecting rod mechanism, the output end of third connecting rod mechanism is moving contact；It is grounded lock
It is rotationally connected with the first input shaft, the first connecting lever part is fixedly connected with the 3rd input shaft, the first connecting lever part drives ground connection lock
Swing.
