Description
Technical field
The utility model belongs to explosion-proof recloser field, is specifically related to a kind of vacuum circuit-breaker sucked type electromagnetic mechanism.
Background technology
Vacuum circuit-breaker sucked type electromagnetic mechanism is a kind of device of supply line, power consumption equipment being implemented the open and close function.At present the electromagnetic mechanism of the vacuum circuit-breaker of producing in the vacuum circuit-breaker industry is two one pole type magnet, and winding volume is bigger, and because of with two coils, used copper material increases greatly, and the cost of electromagnet is higher like this, and power consumption is also big, the easy burn-out coil.
The utility model content
The purpose of this utility model is that solution prior art vacuum circuit-breaker electromagnetic mechanism volume is big, cost is high, efficient is low, the defective of easy burn-out coil, provide that a kind of cost is low, efficient is high, volume is little, the vacuum circuit-breaker sucked type electromagnetic mechanism that performance and functional reliability improve greatly.
The utility model is achieved through the following technical solutions:
It is a kind of vacuum circuit-breaker sucked type electromagnetic mechanism, comprise the armature that is installed on the swinging mounting arm, the armature below is provided with the back-moving spring that is fixed on the body, it is characterized in that on the body below the armature, being provided with the sucked type electromagnet, 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 provided with on the body corresponding with the armature below in the body.
Armature is plate shaped.
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 of the present utility model, cylinder sleeve, chassis also can be integral structures, and can adopt the method one-shot forming of casting this moment.
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 sleeve 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, so just, can reduce the height of circuit breaker, and because of its magnet spool in cylinder body, its volume is reduced greatly, because of an one sucked type electromagnet can replace two one pole type electromagnet, so just can significantly reduce the consumption of copper material again, the material cost of whole electromagnetic mechanism is reduced greatly.
Because of its circuit module with high voltage startup, low voltage sustain is connected, the supply power mode that adopts dc low-voltage to keep than one pole type electromagnetic mechanism, had both been saved electric energy, and easy burn-out coil has not improved the reliability of circuit breaker work again.Even circuit module damages, it is just replaceable to need not to dismantle circuit breaker, very convenient; And one pole type electromagnetic mechanism has been if coil has burnt, maintain and replace must the dismounting circuit breaker can, trouble very.
In sum, the cost of material is low than one pole type electromagnetic mechanism for the sucked type electromagnetic mechanism, both saved the consumption of copper material greatly, can reduce the height of circuit breaker again, also save electric energy, not the easy burn-out coil, improved the reliability of circuit breaker work, and because of circuit module externally, make maintenance, change simple and conveniently, avoided one pole type electromagnet to burn out the trouble of changing behind the coil.
