Abstract
The utility model discloses a dynamic monitoring station for alternating-current contactors, comprising a power supply, a controller and a plurality of groups of alternating-current contactors, wherein the output end of the power supply is electrically connected with the power signal input end of the controller, and the signal output end of the controller is electrically connected with the plurality of groups of alternating-current contactors separately. The dynamic monitoring station for alternating-current contactors in the utility model is simple in structure, can effectively detect unsmooth movement, a blockage and other random failures of the alternating-current contactors, and offers a reliable guarantee for the production and repair of automation equipment.
Description
Technical field
The utility model relates to automation control area, specifically a kind of A.C. contactor dynamic monitoring platform.
Background technology
Automation control system uses A.C. contactor as executive component in a large number, and for guaranteeing the reliability of control, the contacts status that usually needs to detect A.C. contactor judges whether the action of A.C. contactor is reliable.Certain of Chang Yinwei A.C. contactor is once moved unreliable and is made automation control system newspaper fault in the practical application, and correction maintenance is difficult to reappear fault, changes out of order A.C. contactor and also is difficult to avoid it unreliable in certain action once.Insecure A.C. contactor has increased hidden danger of quality and the maintenance cost of equipment.
The utility model content
The purpose of this utility model is to provide a kind of easy A.C. contactor dynamic monitoring platform for the above-mentioned fault of A.C. contactor, and whether occur moving in the number of times of regulation with the detection A.C. contactor unreliable.
The technical solution of the utility model is as follows:
A kind of A.C. contactor dynamic monitoring platform, include power supply, controller and organize A.C. contactor more, it is characterized in that: the output terminal of described power supply is electrically connected with the power supply signal input end of controller, and the signal output part of described controller is electrically connected with many groups A.C. contactor respectively.
Described A.C. contactor dynamic monitoring platform is characterized in that: described controller adopts PLC.
The beneficial effects of the utility model:
The utility model is simple in structure, can be effective detect having some setbacks even certain random fault such as stuck of A.C. contactor action, for production and the maintenance of automation equipment provides reliable guarantee.
Description of drawings
Fig. 1 is the utility model electrical structure diagram.
Embodiment
Referring to Fig. 1, a kind of A.C. contactor dynamic monitoring platform, include 220V power supply, PLC and two groups of A.C. contactor KM1, KM2, the output terminal of power supply is electrically connected with the power supply signal input end of PLC, and the signal output part of PLC is electrically connected with two groups of A.C. contactor KM1, KM2 respectively.
The various interchanges that driven the A.C. contactor action by power generation are given birth to or DC voltage, output control A.C. contactor by PLC moves by the frequency of setting and number of times, input by PLC judges by the time-delay detection A.C. contactor adhesive of setting and the contacts status after the release whether the action of A.C. contactor is reliable, and in the delay time of setting, detecting contacts status, it is qualified that the A.C. contactor that only has the fault-free action number of times to reach the setting requirement just is judged as.When occuring automatically to stop to detect and reporting to the police when detection is defective.
Claims (2)
1. A.C. contactor dynamic monitoring platform, include power supply, controller and organize A.C. contactor more, it is characterized in that: the output terminal of described power supply is electrically connected with the power supply signal input end of controller, and the signal output part of described controller is electrically connected with many groups A.C. contactor respectively.
2. A.C. contactor dynamic monitoring platform according to claim 1 is characterized in that: described controller employing PLC.
