Description
Technical field
The present invention relates to contactor control technology fields, control system more particularly, to a kind of multiple spot rotaing contactor
System.
Background technique
Contactor is divided into A.C. contactor (voltage AC) and D.C. contactor (voltage DC), it be applied to electric power, distribution with
Electricity consumption occasion.Contactor broadly refers to flow through current induced magnetic field using coil in industrial electro, makes contact closure, to reach control
Make the electric appliance of load.The working principle of contactor is：After contactor coil is powered, coil current can generate magnetic field, contactor
The magnetic field of generation makes static iron core generate electromagnetic attraction attraction dynamic iron core, and A.C. contactor point is driven to act, and normally-closed contact disconnects,
Normally opened contact closure, the two are linkages.When the coil is de-energized, electromagnetic attraction disappears, and armature is released under the action of release spring
It puts, restores contact, normally opened contact disconnects, normally-closed contact closure.
Contactor is a kind of control mechanism that circuit can be opened and closed with high-frequency.For industrial application, connect
Tentaculum is widely used for protecting various electrical equipments.Conventionally, as the movement of magnetic systems is horizontal movement or hangs down
Straight movement, so the regular motion of contactor is also horizontal movement or vertical movement based on the simple consideration in design.Contactor
Insulation performance depend on open distance between moving contact and static contact.For high-current circuit, it is necessary to keep dynamic touching
It is sufficient between head and static contact to open away from effectively breaking current.When this meeting is so that the volume of contactor is excessive and disjunction
Between it is too long caused by the contactor service life it is low.
In the prior art, control contactor is realized by contactor actuator or electromagnetic switch, this mode
As soon as the switch state of a contactor can only be often controlled, it is current contactor quantity often one, relatively simple, it cannot achieve
The complex control of multiple contactors, and in electric appliance production line, needs multiple contactors often to carry out complex control, existing
It typically arranges multiple contactors, contactor actuator or electromagnetic switch individually to control, will lead to multiple contacts in this way
Device control position cannot concentrate, and operation is more troublesome.
Summary of the invention
It is rotary that the present invention provides a kind of a kind of multiple spot for overcoming the above problem or at least being partially solved the above problem

Moving contact rack, the static contact component include multiphase static contact, and the moving contact component includes and the multiphase static contact phase
Corresponding single-phase moving contact, the moving contact rack drive the moving contact component rotation to connect with the multiphase static contact when moving
Touching separates；Described control unit is connect with the execution unit, and the execution unit is connect with the switch unit, described fixed
Position feedback unit is connected respectively at control unit and switch unit.
Further,
Including shell, moving contact, rotation axis and the elastomeric element being connect with the moving contact, the elastomeric element setting
Apply in the moving contact bottom and to its moving contact certain elastic force, it is dynamic that the bottom end of the moving contact is provided with outlet
Contact.
Further, each phase static contact of the multiphase static contact is provided with inlet wire static contact, the inlet wire static contact
Outlet stationary contact is set.
Further, the contactor includes control unit and multiple actuators；The actuator respectively with each phase
Rotaing contactor connection.
Further, the contact change-over module includes single-phase movable contact, multiphase stationary contact and rotation connecting shaft；.This hair
It is bright to provide a kind of multiple spot rotaing contactor control system, including control unit, execution unit, contact change-over unit and positioning
Feedback unit composition；The present invention is realized under control unit control action using control unit as the core of entire control system
Actuation and handover operation between each contact of contactor, may be implemented the quick control of a variety of working conditions of multiple contacts.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of multiple spot rotaing contactor control system of the invention.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
As shown in Figure 1, being the structural schematic diagram of multiple spot rotaing contactor control system of the invention.A kind of multiple spot rotation
Formula contactor control system, including control unit, execution unit, contact change-over unit and position feedback unit composition；The rotation
Rotatable contactor includes static contact component, moving contact component and moving contact rack, and the static contact component includes multiphase static contact,
The moving contact component includes single-phase moving contact corresponding with the multiphase static contact, and the moving contact rack drives when moving
The moving contact component rotation is contacted or is separated with the multiphase static contact；Described control unit is connect with the execution unit,
The execution unit is connect with the switch unit, and the position feedback unit is connected respectively at control unit and switch unit.
In an alternate embodiment of the present invention where, above-mentioned moving contact component and the moving contact rack cooperate, to work as
The moving contact rack drives the moving contact component to rotate when moving, and then realizes the contact of the multiphase static contact and divide
It opens.
Moving contact component includes shell, contact, rotation axis and the elastomeric element being connected with the single-phase moving contact, institute
State elastomeric element contact bottom is set and resilient force that it is applied described on moving contact, to guarantee moving contact and every
The realization of one phase static contact comes into full contact with, wherein outlet movable contact is arranged in the bottom of the moving contact.
Each phase static contact of multiphase static contact is provided with inlet wire static contact, and outlet stationary contact is arranged in the inlet wire static contact
Point.
When the multiphase static contact and the single-phase moving contact contact, the moving contact and each phase static contact
The outlet stationary contact realizes contact.
It, will be with the moving contact of the translational motion of magnetic systems based on the contact mechanism of this new type as described above
The up and down motion of bracket is converted into rotary motion (namely rotation of the multiphase moving contact relative to multiphase static contact of contact mechanism
Transhipment is dynamic), wherein the small moving distance of moving contact rack realizes point increased between multiphase moving contact and multiphase static contact
Distance is opened, which reduce the move distance of moving contact rack but there is provided the performances of better cutting electric current.This new type
