Description
Technical field
The utility model belongs to emergency protective circuit device field, relates in particular to all size model leakage comprehensive protector sucked type electromagnetic switch mechanisms such as single-phase, three-phase, three-phase and four-line.
Background technology
Leakage comprehensive protector sucked type electromagnetic switch mechanism; be a kind of supply line load, power consumption equipment are implemented comprehensive integrated protection and had the earth leakage protective device of switching function concurrently; have reliable operation, simple in structure, send advantages such as electricity automatically, not only can be used as the switch of supply load or circuit breaker but also can be used as the electric leakage comprehensive protector of circuit.
The switching mechanism of the leakage comprehensive protector of producing in the earth leakage protective industry is divided into two kinds in electric motor type on-off switch mechanism and electromagnetic type on-off switch mechanism at present.And electromagnetic switching mechanism all adopts the electromagnet that is made of the U font iron core (silicon steel sheet or mild steel etc.) of the folded system of multi-disc and coil, is positioned at the armature on the travel(l)ing rest and is used for the electromagnetism suction type switch motion assembly that back-moving spring that travel(l)ing rest resets constitutes.It adopts the operation principle of " high voltage startup, low voltage sustain ", when the needs electromagnetic switch is closed, coil is sent into a high voltage U to be opened and (mostly is 220V half-wave or all-wave pulsating dc voltage, also can directly send into low-voltage direct), produce electromagnetic force by electromagnet, the downward adhesive of armature is driven switch movable contact contact closure with fixed contact, connect power consumption equipment or line load; After the electromagnetic switch adhesive, again coil is sent into a voltage U of keeping that is not less than release voltage and tie up (pulsating direct current or direct current), to guarantee the lasting, closed reliably of electromagnetic switch.When the needs electromagnetic switch disconnected, to coil blackout, travel(l)ing rest popped up under the effect of back-moving spring, drove switch movable contact and separated rapidly with fixed contact, disconnected power consumption equipment or line load.
But adopt the electromagnetic switch of said structure, because of its iron core of U font electromagnet structure at interior, coil outside, make winding volume relatively large, the cost of electromagnet is just higher relatively like this; Because of U font electromagnet leakage field is big, electromagnetic efficiency is lower, its electromagnetic attraction be guaranteed in addition, its core area can only be strengthened, iron core thickness is increased, both increased difficulty of processing, also increased cost, winding volume also increases simultaneously, and the cost of whole electromagnet is increased greatly; The electromagnet that big current protector is needed is bigger, then adopts two electromagnet simultaneously for easy to process, and the cost on electromagnet is equally very high like this.
Comprehensive above-mentioned reason, the electromagnet cost height of U font structure, efficient is low, volume is big.
Be subjected to the restriction of external volume because of electromagnetic switch; its inner space also is restricted equally; this makes electromagnet dilemma between volume and electromagnetic force of U font structure; be difficult to guarantee of the requirement of protector electromagnetic switch mechanism, had a strong impact on the normal operation and the power supply quality of leakage comprehensive protector the electromagnet electromagnetic force.
The utility model content
The purpose of this utility model is to solve prior art leakage comprehensive protector electromagnetic switch mechanism electromagnetic iron cost height, low, the bulky defective of efficient; provide that a kind of cost is low, efficient is high, volume is little, the leakage comprehensive protector sucked type electromagnetic switch mechanism that performance and functional reliability improve greatly.
The utility model is achieved through the following technical solutions:
It is a kind of leakage comprehensive protector sucked type electromagnetic switch mechanism; comprise the armature that is positioned on the travel(l)ing rest; be positioned at the ON-OFF control circuit of housing; it is characterized in that being provided with on the drain pan and the corresponding sucked type electromagnet of armature on the travel(l)ing rest; described sucked type electromagnet is made up of iron core, cylinder body, coil; columniform iron core passes the center of coil stationary at cylinder body, and coil is connected with the ON-OFF control circuit of high voltage startup, low voltage sustain.
The sucked type electromagnet is arranged on the drain pan position corresponding with travel(l)ing rest upper armature below.
Armature is circular or square or other shape.
Cylinder body is made up of the cylinder sleeve and the circular chassis of tubular, and described cylinder sleeve and chassis are integral structure or split-type structural.When adopting integral structure, the mode of can adopt car, milling is carried out the time processing moulding to section bar; When adopting the split-type structural formula, cylinder sleeve and chassis process respectively, adopt welding or other mode to make up then.
Iron core, cylinder body, armature material are electrical pure iron or mild steel.
Compared with the prior art, the utility model has the advantages that:
The sucked type electromagnet adopt iron core interior, coil placed in the middle, cylinder body totally enclosed type magnetic loop structure outside, and leakage field is reduced greatly, electromagnetic efficiency improves greatly; Under equal-wattage; improved the electromagnetic force of electromagnet greatly; under the suitable situation of electromagnetic force; can correspondingly reduce the volume of electromagnet; both efficiently solved the contradiction of switch inner space and electromagnet volume (influencing electromagnetic force); the electromagnetic force that has guaranteed electromagnet again can satisfy the pressure requirement between dynamic and static contact, and the performance and the functional reliability of protector electromagnetic switch mechanism are improved greatly.
In addition, because of its magnet spool is built in the cylinder body, its volume is reduced greatly, the coil cost reduces greatly, and the processing technology of sucked type electromagnet is simple, and it adds the man-hour cost and reduces relatively, also have because of its electromagnetic efficiency raising, under the suitable situation of electromagnetic force, volume diminishes relatively, just more the cost of its iron core, cylinder body and coil is reduced greatly.
In sum; the sucked type electromagnet than U font electromagnet under the suitable situation of electromagnetic force; volume is little, cost is low; it is little both to have overcome leakage comprehensive protector housing internal cause space; the contradiction that the electromagnet volume is restricted; reliability, the fail safe of protector work improve greatly, and the cost of protector is reduced greatly.
