Description
Technical field
The present invention relates to a kind of reversible magnetic switch, especially relate to the reversible magnetic switch of a kind of many rotary types of driven by power actuator.
Background technology
At present, manual many rotary types actuators can not satisfy modern requirement, and large and medium-sized manual many rotary types actuators is replaced by power-actuated many rotary types actuators just gradually.
The driving of many rotary types actuator is driven by power; magnetic starter realize many rotary types actuator unlatching, closure, stop, the various functions such as local/remote control, and many rotary types actuators is carried out stroke, moment of torsion, leakage ground locking, overload, short circuit, disconnected phase, owes the various protections such as overvoltage.The reversible magnetic switch of the many rotary types actuator that uses is at present controlled as Single Chip Microcomputer (SCM) system or the control of discrete component system.
But use under the environment abominable in condition of work, that electromagnetic environment is complicated, interference signal is strong, the reversible magnetic switch of existing many rotary types actuators exists following problem:
(1) reliability, stability and anti-interference are poor, and the misoperation phenomenon occurs often;
(2) after local/remote is controlled, self-sustaining/wink, moving operation selection needed outage, next could the realization of dismounting wire connection cavity change wiring, real time altering uses as required, and is safe not, convenient.
(3) A.C. contactor of controlling many rotary types actuators forward and backward breaks down because of problems such as voltage or magnetic coils, and during cisco unity malfunction, whether reversible magnetic switch does not judge the A.C. contactor adhesive, and it is carried out defencive function.
Due to first-class problem, cause and produce and accident potential occurs safely, demand urgently being improved.
Summary of the invention
Be the problems referred to above that solve that present Single Chip Microcomputer (SCM) system is controlled or the reversible magnetic switch of the discrete component system controls many rotary types actuators exists, many rotary types of the driven by power actuators reversible magnetic switch that the invention provides that a kind of reliability is high, antijamming capability is strong, multiple functional.
The major function that the present invention has has: (1) realize to the local/remote of many rotary types actuators control, open, closed, stop, the controls such as self-insurance/wink is moving, stroke limit, torque limit; (2) contacts of contactor that occurs in the work of many rotary types of Real Time Monitoring actuators is not closed, current overload, short circuit current, phase shortage, owe overvoltage, leak the faults such as ground locking resistance, realizes the integrated protection to many rotary types actuator; (3) local/remote is controlled, is moved in self-sustaining/wink to move and select and can arrange on touch-screen, realizes real time altering.(4) utilize touch-screen that the related work parameter is arranged, dynamically show aperture size and the relevant parameter of many rotary types actuator, and show in real time type and the parameter of fault; (5) fault of the working condition of many rotary types actuator, generation and time etc. are saved in touch-screen, and can real time inspection.
The technical solution adopted for the present invention to solve the technical problems is: using the Programmable Logic Controller that reliability is high, antijamming capability is strong industrial circle uses instead is control core.The magnetic starter panel is provided with a test model/mode of operation selector switch, and a touch-screen is opened (↑), closed (↓), stopped (confirmations) three buttons and all operate on touch-screen, and side has an isolation reversing switch, and two pass in and out spools.
