Abstract
The utility model relates to a control device in the electrical equipment field, especially to a soft start cabinet. An air switch, a soft starter and an alternating-current contactor are arranged in a cabinet body; the soft starter is connected in series with the air switch; and the alternating-current contactor is connected in parallel with the soft starter. In addition, the soft start cabinet also includes an automatic control module that is respectively connected with the soft starter and the alternating-current contactor. On the basis of the structure, the automatic control module is used to control switching between the soft starter and the alternating-current contactor. When the soft starter completes soft starting, the soft starting is disconnected and the alternating-current contactor is connected to replace the soft starter, thereby realizing automatic controlling. In addition, after motor bypass, that is, the alternating-current contactor, is operated, the soft starter uses a mutual inductor connected in series to a main loop to carry out gapping, overloading, and three-phase unbalance protection on the motor; and real-time current monitoring is also realized. A power transformer is used to carry out overvoltage and undervotlage protection and voltage monitoring on the motor and the functions are diversified, so that the whole system can be operated stably.
Description
Technical field
The utility model relates to a kind of appliance field control device, especially a kind of soft start cabinet.
Background technology
Starter (claiming soft starter again, motor soft starter) soft initiator be the soft start of a kind of current collection machine, soft stop, light-load energy saving and kinds of protect function in the novel motor control assembly of one, be called Soft Starter abroad.Its main composition is three-phase inverse parallel brake tube and the electronic control circuit thereof that is serially connected with between power supply and the controlled motor.Use diverse ways, the angle of flow of control three-phase inverse parallel brake tube makes the input voltage of controlled motor change by different requirements, just can realize different functions.During the soft initiator actuating motor, the output voltage of thyristor increases gradually, and motor accelerates gradually, and up to the full conducting of thyristor, motor is operated on the mechanical property of rated voltage, realizes smoothly starting, and reduces starting current, avoids starting overcurrent tripping.When treating that motor reaches rated revolution, start-up course finishes.
But soft initiator only; after complete conducting; Yun Hang words always; the thermal losses of soft initiator is very serious, influences the useful life of soft initiator, can cooperate A.C. contactor to realize that band replaces soft initiator usually; in case yet after the A.C. contactor conducting; soft initiator has not just been worked, and does not have other purposes, and the difficult assurance on closed opportunity of A.C. contactor.
Summary of the invention
The purpose of this utility model is, a kind of automatic control, stable, multi-functional soft start cabinet are provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of soft start cabinet, comprise cabinet, air switch, soft initiator, A.C. contactor, air switch, soft initiator, A.C. contactor are arranged in the cabinet, soft initiator is connected with air switch, A.C. contactor is in parallel with soft initiator, also comprise automatic control module, automatic control module is connected with soft initiator, A.C. contactor respectively.
Of the present utility modelly further be set to: also comprise the current transformer of connecting with major loop, current transformer is connected with soft initiator.
Of the present utility modelly further be set to: also comprise power transformer, power transformer is connected with soft start.
Of the present utility modelly further be set to: described automatic control module comprises handover module, detection module, detection module is connected with soft initiator, handover module is connected with soft initiator, A.C. contactor respectively, and handover module, detection module are connected with single-chip microcomputer respectively.
Said structure passes through automatic control module; the switching of control soft initiator and A.C. contactor; when soft start is finished soft start; disconnect soft start; make the A.C. contactor adhesive replace soft initiator; realize control automatically; after motor bypass in addition (A.C. contactor) operation; soft starter is also carried out lacuna by sealing at the instrument transformer of major loop to motor, overload, three electric unbalance protections; and real-time monitoring current; can carry out overvoltage and under-voltage protection and voltage monitoring to motor by power transformer, function ratio is more, makes the whole system operation more stable.
Description of drawings
Fig. 1 is the structure diagram of embodiment;
Fig. 2 is the schematic diagram of present embodiment control module.
Embodiment
With reference to figure 1 as can be known, a kind of soft start cabinet, comprise cabinet 1, air switch, soft initiator, A.C. contactor 2, air switch, soft initiator, A.C. contactor 2 are arranged in the cabinet 1, soft initiator is connected with air switch, and A.C. contactor 2 is in parallel with soft initiator, and automatic control module is connected with soft initiator, A.C. contactor 2 respectively, current transformer is connected with soft initiator, and power transformer is connected with soft start.
With reference to figure 2 as can be known, automatic control module comprises handover module, detection module, detection module is connected with soft initiator, detect the situation of soft initiator, handover module respectively with soft initiator, A.C. contactor connects, handover module, detection module is connected with single-chip microcomputer respectively, after detection module detects soft initiator and finishes startup, single-chip microcomputer disconnects by handover module control soft initiator, A.C. contactor 2 adhesives, detection module is responsible for detecting soft initiator from power transformer simultaneously, the signal that current transformer obtains, thus transfer to single-chip microcomputer, calculated by single-chip microcomputer and carry out various command.
Obviously, above-described embodiment only be for explanation clearly do for example, and be not restriction to execution mode.To those of ordinary skill in the art, can also make other changes in different forms on the basis of the above description.Here need not also can't give all execution modes exhaustive.And the apparent variation of being extended out thus or change still are in the protection range of the present utility model.
