Abstract
The utility model discloses a protecting device of a doffing power supply of a spinning machine and is used for being installed between a transformer and the spinning machine. The protecting device comprises a breaker connected with an output terminal of the transformer, the breaker is connected with an alternating current contactor, the alternating current contactor is connected with a driving device of the spinning machine, the alternating current contactor is also connected with a time relay, and an output terminal of the time relay is connected with a power supply input terminal of the transformer. A three-phase safety core of an original machine bench of the spinning machine is removed, and the breaker, the alternating current contactor and the time relay are additionally provided. If the load of the spinning machine is over-heavy, the breaker automatically powers off, a motor of the spinning machine and the transformer are protected, and the motor of the spinning machine and the transformer are prevented from being burnt out; the time relay automatically powers off in a preset time after the spinning machine completes doffing, and long-time electrification of the transformer is eliminated. According to the protecting device, the transformer is prevented from being damaged, hidden risks of work are avoided, the production benefit is substantially increased, and the fitting cost is reduced.
Description
Technical field
The utility model relates to a kind of textile machine, relates in particular to a kind of doffing of spinning frame apparatus for protecting power supply.
Background technology
FA502 type doffing of spinning frame power supply in use, because doffer load is overweight, easily causes and burns out insurance or damage transformer, causes doffing and stops platform or dangerous operation generation, and after having doffed, transformer is long charged simultaneously, for production safety has been buried hidden danger.
Utility model content
Technical problem to be solved in the utility model is to provide one and avoids occurring transformer damage, has stopped work safety hidden danger, and effect significantly, improves productivity effect greatly, has saved the doffing of spinning frame apparatus for protecting power supply of fittings cost.
For solving the problems of the technologies described above; the technical solution of the utility model is: doffing of spinning frame apparatus for protecting power supply; be used for being arranged between transformer and spinning frame; comprise the circuit breaker being connected with transformer output; described circuit breaker connects A.C. contactor; described A.C. contactor connects the drive unit of described spinning frame, and described A.C. contactor is also connected with the time relay, and the output of the described time relay is connected with described transformer frequency response input.
As preferred technical scheme, the normally opened contact of described A.C. contactor is connected with the drive unit of described spinning frame.
As the improvement to technique scheme, the normally-closed contact of described A.C. contactor is connected with the time relay.
Owing to having adopted technique scheme; doffing of spinning frame apparatus for protecting power supply; be used for being arranged between transformer and spinning frame; comprise the circuit breaker being connected with transformer output; described circuit breaker connects A.C. contactor; described A.C. contactor connects the drive unit of described spinning frame, and described A.C. contactor is also connected with the time relay, and the output of the described time relay is connected with described transformer frequency response input.The three-phase of the former board of spinning frame insurance core is removed, install each one of described circuit breaker, described A.C. contactor and the described time relay additional.If described spinning frame load is overweight, auto-breaking of described circuit breaker, protection spinning frame electric motor and transformer, avoid spinning frame electric motor and transformer to be burned; The described time relay, after doffing of spinning frame completes, at default stipulated time auto-breaking, is stopped transformer long charged, reduces potential safety hazard.The utility model is avoided occurring transformer and is damaged, and has stopped work safety hidden danger, and effect significantly, improves productivity effect greatly, has saved fittings cost.
Brief description of the drawings
The following drawings is only intended to the utility model to schematically illustrate and explain, does not limit scope of the present utility model.Wherein:
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.In the following detailed description, only by the mode of explanation, some example embodiment of the present utility model has been described.Undoubtedly, those of ordinary skill in the art can recognize, in the situation that not departing from spirit and scope of the present utility model, can revise described embodiment by various mode.Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection range of claim.
As shown in Figure 1; doffing of spinning frame apparatus for protecting power supply; be used for being arranged between transformer and spinning frame; comprise the circuit breaker being connected with transformer output; described circuit breaker connects A.C. contactor; described A.C. contactor connects the drive unit of described spinning frame; the drive unit of described spinning frame is the motor that drives spinning frame for a person skilled in the art; described A.C. contactor is also connected with the time relay, and the output of the described time relay is connected with described transformer frequency response input.The three-phase of the former board of spinning frame insurance core is removed, install each one of described circuit breaker, described A.C. contactor and the described time relay additional.If described spinning frame load is overweight, auto-breaking of described circuit breaker, protection spinning frame electric motor and transformer, avoid spinning frame electric motor and transformer to be burned; The described time relay, after doffing of spinning frame completes, at default stipulated time auto-breaking, is stopped transformer long charged, reduces potential safety hazard.The present embodiment is avoided occurring transformer and is damaged, and has stopped work safety hidden danger, and effect significantly, improves productivity effect greatly, has saved fittings cost.
The normally opened contact of described A.C. contactor is connected with the drive unit of described spinning frame.When described transformer is described spinning frame power supply, the coil electricity of described A.C. contactor, described normally opened contact closure, for described spinning frame power supply, makes its work.
The normally-closed contact of described A.C. contactor is connected with the time relay.In the time that described transformer stops as described spinning frame power supply, be after described doffing of spinning frame completes, the coil losing electricity of described A.C. contactor, the normally-closed contact closure of described A.C. contactor, the described time relay obtains after signal, at default stipulated time auto-breaking, stop transformer long charged, reduce potential safety hazard.
More than show and described general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
