Abstract
The utility model relates to a self-control protector, which can realize automatic stop during phase loss, cracked ends and broken picks of the loom motor and display alarm signals right away during the phase loss. The protector is provided with a circuit system comprising an alternating current contactor Jc [1], an electronic switching circuit [2], a phase loss alarm display circuit [3] and a weaving stop detecting switch K-[2][4]. The protector can effectively protect the motor from burning, the loom does not generate trapped shuttles resulting in waste products. The utility model has the advantages of simple structure, high reliability, energy saving, long service life and low maintenance cost, and is widely used in circuit operating control parts of various looms.
Description
The utility model is used to weave cotton cloth motor when the phase failure, cracked ends, staplings, can realize autostop, and when the phase failure a kind of auto-control protective device of display alarm signal immediately.
Traditional loom generally adopts the three-phase press button, and controls the rotation of motor as the method for short-circuit protection or stop with three insurances, and when the power supply phase shortage, motor can not hard stop, alarm free display unit again, thus cause motor to burn easily.When loom during at cracked ends, staplings, then can quit work by clutch, this moment, motor was still at free-runing operation, impel motor accelerated wear test like this, shorten its service life, in addition then, sometimes malfunctioning because of the loom clutch again, and cause trapped shuttle to produce waste product, thus influenced product yield and quality.
Task of the present invention is: provide a kind of when power supply phase shortage or loom cracked ends, staplings; motor can be shut down rapidly, and when the power supply phase shortage, immediately the display alarm signal; thereby reach the saving electric energy, protect motor not burnt, and can improve product yield and quality effectively.
This multifunctional self-regulating device is by A.C. contactor Jc (1), electronic switching circuit (2), phase shortage alarm indication circuit (3) with stop knitting sense switch K by one
2(4) Circuits System of Zu Chenging is controlled the rotation of the motor of weaving cotton cloth or is stopped, and its operation principle is: (seeing accompanying drawing 1)
When power supply just often, the electric current of being imported mutually by A, B is through dropping resistor R

3Triggering and conducting IGCT BT
1, input C phase power supply behind A.C. contactor Jc (1) coil, A.C. contactor adhesive action, the conducting electric motor starting, loom can drop into normal operation.
Lack a phase time when power supply A, B appoint mutually, then no current input impels C phase no current conducting A.C. contactor Jc this moment (1) to reset or does not have the adhesive action, and motor then shuts down immediately.Maybe can not start, simultaneously, because resistance R

8The star interface and ground wire between appearance potential poor, light emitting diode D then
3, luminous immediately warning shows phase shortage, diode D
4Reverse-conducting, protection light emitting diode D
3Reliability service.
When loom during at cracked ends, staplings, the loom control stick automatically resets, and stops knitting sense switch K
2(4) closing of contact is impelled IGCT BT
1The trigger current bypass that control is extremely gone up, IGCT BT
1End, A.C. contactor resets, and motor quits work immediately.
This auto-control protective device and existing three-phase press button relatively have following advantage: when loom during at power supply phase shortage or loom cracked ends, staplings; can reach the purpose of autostop; and when the phase failure; can send alarm signal rapidly; thereby protected motor not burnt effectively; loom does not produce trapped shuttle and causes waste product to occur; advantages such as that this protector has is simple in structure, dependable performance, saving electric energy, motor long service life, maintenance cost are low, and the electrical equipment that can be widely used in various looms is handled control section.
