Description
Technical field
The invention belongs to a kind of disconnecting switch, and in particular to a kind of super-large current high voltage isolator.
Background technology
Operationally heat dissipation problem and the dropout of dropout locking device are most important for super-large current high voltage isolator, otherwise can
Cause the consequences such as switch heating is serious, can not lock, it is impossible to normally use.Currently used heavy current disconnecting switches conduction is returned
Road part does not take the related cooling measure that reduces to cause switch normally to use, and is often deposited when particularly electric current is more than 6300A
The situation of switching electric fields effect is had a strong impact in magnetic field effect, Kelvin effect etc., causes to switch serious heating, traditional high current
The framework of disconnecting switch is welded using Q235 material plates, and switch is caused in the presence of strong magnetic field effect in actual motion
Galvanic circle temperature rise superelevation, have a strong impact on the actual motion of switch；Traditional dropout locking device has two kinds of forms, and one kind is logical
Cross ball and rolled in the groove of connecting rod and reach separating brake, combined floodgate and locking state, it is when ball is rolled out out of groove, ejector pin is outside
Top, holds out against magnetic lock plate, realizes locking action.Using ball grooves slide block structure, the size of power and the shape of groove have larger during locking
Relation, the size of the pressure angle contacted depending on ball with groove is small when big during the effect of power, thus causes power uneven.In work
When making, cause sometimes device for switching can not in-place closing, have impact on the reliability used.Another is using more complicated
Trip gear, it is made up of locking and trip gear two parts, yielding in this trip gear operating process, easily produces mistake
Operation, so as to cause accident.Although have using anti-locking plate structure, anti-jam plate is in fluting time slot and the angle of horizontal direction
For 90 degree, it is not inconsistent with actual motion track, the release pin on sliding block can be interfered in motion process, add the behaviour of switch
Make power.

Main shaft connecting lever is provided with pull bar, pull bar is connected with each other with the longitudinal sliding block with release pin, made under pull bar drive
It must be acted with the longitudinal sliding block of release pin；
Set respectively on two contact knifes and be respectively cooperating with setting a horizontal slide-bar, the outer end of horizontal slide-bar in sliding sleeve, each sliding sleeve
Connected respectively with corresponding magnetic lock plate, set between the inner and longitudinal sliding block with release pin of two horizontal slide-bars and promote dress
Put；
The centre symmetry line of anti-jam plate and the angle of longitudinal sliding block vertical direction are 3 ° ~ 11 °.
Pillar is disposed between described engagement plate and underframe, pillar is mutually permanently connected with touch base.
Described extends into pull bar between the horizontal slide-bar being symmetrically distributed, and pull bar top is mutually contradicted with connecting rod,
Connecting rod is opened on top upwards under the upward active force of pull bar.
Two described connecting rods are arranged symmetrically between horizontal slide-bar and longitudinal sliding block with release pin, and the two of each connecting rod
End is hinged with corresponding horizontal slide-bar with the longitudinal sliding block with release pin respectively.
Pull bar is extended with cavity structure inside described horizontal slide-bar, the limiting component is symmetrical company
Bar.
Described connecting rod is acted in opposite directions under pull bar ejection action, and when connecting rod runs into limiting component, stopping is acted.
It is an advantage of the invention that：In disconnecting switch be provided with longitudinal sliding block and pull bar, can allow disconnecting switch action more
Plus safety and rationally, will rational angle be set between anti-jam plate and longitudinal sliding block, can allow disconnecting switch motion when
Wait track more accurate, will not be disturbed by other equipment, use more simple and life, two connecting rods
It is arranged symmetrically between transverse slider and longitudinal sliding block, the two ends of each connecting rod are cut with scissors with corresponding transverse slider and longitudinal sliding block respectively
Connection.Gradually reinforced during completing locking and closing a floodgate, than more uniform, add the reliability of the present invention, improving makes
Use the life-span.
