Abstract
The utility model relates to a soft starter, including silicon controlled rectifier, treater, operating panel, radiator, fan, the treater passes through drive circuit to be connected with the silicon controlled rectifier, treater and operating panel interconnect, and the treater is connected with the fan, and the setting is hugged closely on the silicon controlled rectifier to the radiator, and the fan setting is in radiator one end. The utility model discloses having cancelled ac contactor short -lived, that break down easily, having cancelled the contactor bypass simultaneously, guarantee through keeping the silicon controlled rectifier to switch on for a long time that lasting of motor moves behind the motor soft start, simplified the product structure, the reduce the fault point overhauls more easily, improves life, has reduced the manufacturing cost of product moreover.
Description
Technical field
The present invention relates to a kind of soft starter of motor.
Background technology
Soft starter is a kind of Electric Machine Control equipment integrating soft start, soft stop, light-load energy saving and multifunction protection.Adopt soft starter, motor starting voltage can be controlled, make it raise gradually in starting process, very naturally control starting current.
But existing soft starter is after completing starting process, be switched to by-path running status, how to be switched to running status smoothly, this is also a difficult point of soft starter, and it is extremely important how to make an accurate selection of bypass point.Early, rush of current is very large, even if under lower pressure, also can cause circuit breaker trip in three phase mains, even can damage circuit breaker for bypass point.Endanger larger under condition of high voltage.Late, motor vibrating obtains severe bypass point, affects load and normally works.Therefore, the hardware detecting circuit of by-passing signal must be very accurate, and routine processes is also just right.And bypass usually adopt contactor as connect switch, the useful life of contactor is shorter, easily damages after switch repeatedly, causes the failure rate of soft starter higher, reliability and useful life low.
Summary of the invention
For above-mentioned reasons, the invention provides a kind of soft starter not needing A.C. contactor, there is structure simple, the advantages such as fault point is few, long service life.
For achieving the above object, the present invention adopts a kind of soft starter to comprise controllable silicon, processor, guidance panel, radiator, fan, processor is connected with controllable silicon by drive circuit, processor is connected alternately with guidance panel, processor is connected with fan, radiator is close to and is arranged on controllable silicon, and fan is arranged on radiator one end.
The present invention is specifically set to described soft starter and comprises housing, and radiator is arranged on housing bottom surface, and controllable silicon is arranged on a heat sink, fan is arranged on one end of radiator, towards radiator blowing, guidance panel is arranged in case top lid, and processor is arranged on inside case top lid.
The present invention is specifically set to soft starting cabinet, comprise cabinet and circuit breaker, the output of circuit breaker is connected with silicon controlled input, radiator is arranged in cabinet floor, controllable silicon is arranged on a heat sink, and fan is arranged on the cabinet of one end of radiator, towards radiator blowing or air draught, guidance panel is arranged on cabinet and covers, and processor is arranged in cabinet.
The present invention is specifically set to described radiator is provided with temperature sensor, and temperature sensor is connected with processor.
The invention has the beneficial effects as follows: eliminate the A.C. contactor that the life-span is short, easily break down, cancel contactor bypass simultaneously, by the continuous service keeping the long-time conducting of controllable silicon to ensure motor after flexible starter for electric motor, simplify product structure, reduce the fault point, more easily overhaul, improve useful life, and reduce the production cost of product.Arrange fan in radiator side, control fan by processor, when controllable silicon runs, fan rotates and improves air passage rates, improves the radiating efficiency of radiator, ensures controllable silicon long-time steady operation.Radiator is provided with temperature sensor, and temperature sensor is connected with single-chip microcomputer, the temperature of feeds back heat-sink, and when radiator is overheated, monolithic function disconnects controllable silicon, protection controllable silicon.
