Abstract
The utility model discloses a kind of driving contactors, three-phase electricity including input terminal, the fastp-acting fuse being electrically connected in three-phase electricity, and fastp-acting fuse is electrically connected at the pin of solid-state relay integrated package, the lower end pin of the solid-state relay integrated package is electrically connected at motor, and the solid-state relay integrated package is additionally provided with close to switch." fever " problem that the variation of immediate current caused by the frequent " on " of contactor, "off" generates is avoided, the adhesion of contactor generation is avoided, to reduce the failure-frequency of contactor, realizes the safe and effective operation of travelling facility.
Description
Technical field
The utility model relates to electric-controlled mechanical technical field, specially a kind of driving contactor.
Background technique
Driving is widely used in industrial enterprise, operates dynamic row system, and traditional approach (mechanically may be used using a kind of contactor
Frequently to contact, disconnect) mechanical electric apparatus component, in the very high situation of frequency of use, often occur pick-up current lacuna or
Adhesion is in contact bad error.Its working principle: by the on-off of induction coil electric current, contactor is made to realize " machine
Tool formula " switches on and off, to realize control and convert the operation of travelling facility.Due to continually being operated during production operation
When (variation of handling movement), the frequent size of current variation of contactor coil accordingly will cause, the variation of immediate current causes line
Phenomena such as circle fever, contactor " be attracted adhesion " or accessory loosen, it is out of control even to occur and causes safety accident happens occasionally.Such as
Fruit production operation environment is bad, such as: environment temperature height, dust factor, then can take place frequently such failure, influence normally to produce and make
Industry activity.
Utility model content
The purpose of this utility model is to provide a kind of driving contactors, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions:
A kind of driving contactor, the three-phase electricity including input terminal, the fastp-acting fuse being electrically connected in three-phase electricity, and it is fast
Fast fuse is electrically connected at the pin of solid-state relay integrated package, and the lower end pin of the solid-state relay integrated package electrically connects
It is connected to motor, the solid-state relay integrated package is additionally provided with close to switch.
Preferably, the fastp-acting fuse has three groups, is FU1, FU2, FU3
Preferably, SSR PP8S50A1, SSR DF8S45A1 Schneider solid-state can be selected in the solid-state relay integrated package
Relay.
Preferably, described to select specification ABS130-22150DK close to switch.
Compared with prior art, the utility model has the beneficial effects that being replaced using " solid-state relay (semiconductor-type) "
" coil type contactor (mechanical) " that tradition uses preferably realizes and " connects in driving operation and frequent movement change procedure
The balance of tentaculum moment three-phase current " avoids what the variation of immediate current caused by the frequent " on " of contactor, "off" generated
" fever " problem, avoids the adhesion of contactor generation, to reduce the failure-frequency of contactor, realizes travelling facility peace
Entirely, it effectively runs.
Detailed description of the invention
Fig. 1 is the tradition driving automatically controlled schematic diagram of contactor；
Fig. 2 is semiconductor solid-state contactor model.
In figure: fastp-acting fuse 1, solid-state relay integrated package 2, close switch 3, motor 4.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides a kind of technical solution referring to FIG. 1-2:
A kind of driving contactor, the three-phase electricity including input terminal, the fastp-acting fuse 1 being electrically connected in three-phase electricity, fastly
Fast fuse 1 has three groups, is FU1, FU2, FU3, and fastp-acting fuse 1 is electrically connected at the pin of solid-state relay integrated package 2,
SSR PP8S50A1, SSR DF8S45A1 Schneider solid-state relay can be selected in solid-state relay integrated package 2.Solid-state relay collection
Blocking 2 lower end pin is electrically connected at motor 4, and solid-state relay integrated package 2 is additionally provided with close to switch 3, close to switch choosing
With specification ABS130-22150DK(voltage rating U:10-30VDC rated current I:200mA), and including control motor 4 just,
Reverse turn.
Working principle explanation: solid-state relay integrated package is controlled by small voltage, open and close is realized, makes to load
(motor) realizes starting, stops or turn to.
" coil type contactor (mechanical) " for replacing tradition to use using " solid-state relay (semiconductor-type) ", preferably
It realizes in driving operation and frequent movement change procedure " balance of contactor moment three-phase current ".
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
