Description
Technical field
The present invention relates to a kind of novel high speed grounding switches.
Background technique
In sulfur hexafluoride gas insulation metal sealed switchgear, high speed grounding switch configures the outlet in transmission line circuit
Disconnecting switch leans on route side, and there are two effects for it:
1. capacitance current and electromagnetic induction generation inductive current that folding parallel aerial route is generated due to electrostatic induction；
2. high speed grounding switch is fast by major loop when creepage phenomenon or interior of shell arcing occurs in interior of shell insulator
Quick access, fault current is cut off using breaker.
So high speed grounding switch is needed to have the function of following two:
1. structure is simple, operation is reliable.
2. switching synchronization and enough intensity between contact.
But often structure is complicated for existing high speed grounding switch, and excessively relies on electronic building brick, so whole structure is steady
It is qualitative not strong, and A, B, C three-phase need to be correspondingly provided with three contacts, three traditional contacts control ground connection respectively, it is easy to make
There is interval at three contact ground connection times, to cause unnecessary safety accident.
Summary of the invention
The purpose of the present invention is to solve the above the deficiencies in the prior art, propose the novel rapid grounding of one kind and open
It closes.
A kind of novel high speed grounding switch, including shell and vertical motion assemblies；The vertical motion assemblies pass through
Crank link mechanism is connected with shell, and the bottom of vertical motion assemblies is connected with insulation support plate, the bottom of the insulation support plate
Portion is sequentially connected with contact A, B, C, and described contact A, B, C pass through the respective row that is flexible coupling and be connected with ground terminal, described
The row that is flexible coupling is flexible U-shaped metalwork, and the side of the U-shaped metalwork is connected with contact A, B, C respectively, the other side and
Ground terminal is connected, and the ground terminal is connected with the outer wall of shell.
Preferably, the crank link mechanism includes drive shaft and connecting lever, and shell is stretched out simultaneously in one end of the drive shaft
It is connected to the motor, the other end of drive shaft and the upper end of connecting lever are hinged, the lower end of the connecting lever and the side of vertical motion assemblies
Wall is hinged.
Preferably, the side of the U-shaped metalwork is connected with contact A, B, C respectively by the vertical battery plate that connects.
Preferably, the back side of the vertical motion assemblies is connected with sliding block, is equipped in the shell and erects with what sliding block matched
To sliding rail.
The utility model has the advantages that
1, vertical motion assemblies are driven to move up and down by crank link mechanism, to complete the on/off switch behaviour of three contacts
Make, overall structure is simple and reliable, it is only necessary to which an action component can be achieved with the up and down action of contact, and by three-phase contact (contact
A, B, C) it is mounted on same insulation support plate, guarantee that high speed grounding switch is improved while switching synchronization resists alternate electricity
The ability of power.
2, pass through the row that is flexible coupling of U-shaped, it is ensured that when vertical motion assemblies move up and down, contact is remained and connect
The good electric conductivity of ground terminal, to guarantee the reliable and stable of single unit system.
