Description
Technical field
The invention belongs to power switchgear technical fields, and in particular to a kind of transmission mechanism of earthing switch.
Background technology
Current earthing switch on the market is closed to be closed using isolation switch, and shortcoming is to carry out contact appearance when ground connection closes
Easy ablation generates metallic ionization, pollutes seal case internal environment, influences the through-current capability and dielectric level of major loop.
It is general using the ground connection vacuum interrupter with high ground connection making capability in order to improve making capability, and often improve entire
The cost of switchgear.
To solve the above-mentioned problems, present applicant proposes a kind of double arc extinguishing chambers earthing switch, wherein double arc extinguishings
Room earthing switch is connected using the priority that isolation ground connection three position mechanism makes ground connection vacuum interrupter exist in logic with isolation switch
Lock.Isolation ground connection three position mechanism therein is grounded arc extinguishing room module to realize driving isolation shaft three station point by increase and decrease
The lose-lose that the uniaxial output mode of conjunction realizes isolation division to driving isolation shaft and ground connection vacuum interrupter ground connection is driven to close
Go out pattern.
But the ground connection arc extinguishing room module of above-mentioned earthing switch, in separating brake and combined floodgate, main spring exits latched position, by
In the self-closing power reason of arc-chutes, mechanism can not continue to keep open position, and therefore, when separating brake cannot lock, and in closing position
When also without locking device so that separating brake and close a floodgate all there are it is unstable the problem of.It is also general in this field of switch drive
Store-through enables the locking for realizing separating brake or closing position, existing skill the problem of either closing position cannot lock separating brake
Structure in art is also very complicated.
Invention content
It is an object of the invention to overcome switch drive separating brake in the prior art and what closing position can not lock asks
Topic, so as to provide a kind of transmission mechanism simple in structure, realizing switch separating brake and the earthing switch of closing position locking.
To realize above-mentioned technical purpose and the technique effect, a kind of transmission mechanism of earthing switch of the present invention, packet
