Description
Technical field
The utility model relates to a kind of electronic overload relay magneto solenoid type actuating mechanism.
Background technology
At present, the actuating mechanism that electronic overload relay uses is the clapper-type structure, and its motion mode is a support motion, and auxiliary contact is a vertical bar shaped, the part shape complexity, and auxiliary contact is asynchronous, and it is poor to connect reliable breaking.
Summary of the invention
The utility model provides a kind of electronic overload relay magneto solenoid type actuating mechanism, to overcome the defective that clapper-type electronic overload relay actuating mechanism exists.
For achieving the above object, technical solutions of the utility model are to adopt magneto solenoid type actuating mechanism, electromagnetism counter-force that it produces by magneto solenoid type electromagnetic system and suction operation supporter do the horizontal parallel motion often reach open, normally closed auxiliary contact break-make purpose.This actuating mechanism comprises magneto solenoid type electromagnetic system and contact support.Magneto solenoid type electromagnetic system is made up of winding coil and the strip permanent magnet and " L " sections core that are contained in the coil rack.The contact support is the bar shaped supporter, bar shaped supporter one end is equipped with the dropout spring, auxiliary contact and normally closed auxiliary contact are often opened in assembling above the bar shaped supporter, the movable contact spring of often opening auxiliary contact and normally closed auxiliary contact is " U " shape, the fit beneath of bar shaped supporter and electromagnetic system carry out " L " type armature that magnetic is got in touch, and this supporter and the member that is assemblied in above it move horizontally.
Winding coil can have shared or two coil racks independently, two windings are respectively the dropout winding and the winding that resets, every kind of coil has inside and outside two loops, a loop is the electronic control system of this relay, another is outside external loop, two loops can both be sent to coil separately and be threaded off and the homing action instruction, produce the dropout and the electromagnetic force that resets, and relay is threaded off and homing action.
The contact support of strip structure helps rectilinear motion, with square, the circular design space that more interface structure is relatively arranged, helps the layout of structural member and adaptive, dwindles space layout; And can make the direction of motion of spring force, auxiliary contact pressure and actuating mechanism consistent, help mechanism kinematic.
Often open auxiliary contact and normally closed auxiliary contact movable contact spring increased contact fracture quantity for " U " shape structure, help the contact electrical property and the bar shaped supporter can have good respective outer side edges.
The utlity model has the parts simple shape, rational in infrastructure, auxiliary contact is good synchronously, connects advantages such as reliable breaking.
Below in conjunction with drawings and Examples technology contents of the present utility model is described further.
Description of drawings
Fig. 1 is the structure diagram of the utility model electronic overload relay magneto solenoid type actuating mechanism.
Fig. 2 is the structural representation of a kind of embodiment of the utility model electronic overload relay magneto solenoid type actuating mechanism.
Embodiment
As shown in Figure 1 and Figure 2, this electronic overload relay magneto solenoid type actuating mechanism comprises magneto solenoid type electromagnetic system and contact support.Magneto solenoid type electromagnetic system is made up of winding coil 8 and the strip permanent magnet 11 and " L " sections core 7 that are contained in coil rack 9.The contact support is a bar shaped supporter 2, bar shaped supporter 2 one ends are equipped with dropout spring 1, dropout spring 1 one ends and bar shaped supporter one end in contact, its other end is fixed on the body 10, auxiliary contact 4 and normally closed auxiliary contact 3 are often opened in assembling above the bar shaped supporter, often open auxiliary contact and normally closed auxiliary contact movable contact spring for " U " shape, assembling is carried out " L " type armature 6 that magnetic is got in touch with electromagnetic system below the bar shaped supporter 2, this supporter and the member that is assemblied in above it move horizontally.Also be provided with on the bar shaped supporter 2 and have the interface structure M that manual manipulation is used.Present embodiment also is provided with back-moving spring 5 at the other end of bar shaped supporter, to improve the restoring force of bar shaped supporter.
Winding coil 8 can be divided into two windings, have shared or two coil racks 9 independently, two windings are respectively dropout winding 8A and the winding 8B that resets, every kind of coil has inside and outside two loops, a loop is the electronic control system of this relay, and another is outside external loop, and two loops can both be sent to coil separately and be threaded off and homing action instructs, produce and thread off and the electromagnetic force that resets, relay is threaded off and homing action.
In order to make this relay actuator winding have remote Electromagnetically-operating function, present embodiment also is provided with the external socket of winding, two terminations of dropout winding 8A and logic system interface, in addition again with socket termination interface, the socket termination can connect with outside power supply easily, as when the outside imposes the instruction identical with logic system, also can make the actuating mechanism action.The winding 8B that resets is the same with dropout winding 8A, also has external socket, can carry out remote electromagnetism and reset when applying additional power source.
Under the normal operation; contact is supported the closure state of armature 6 on 2 holding armature 6 and permanent magnet 7 under the magneticaction of permanent magnet 7; normally closed auxiliary contact 3 is in closure; often opening auxiliary contact 4 opens; when main circuit or motor appearance overload; during faults such as the phase failure; the logic system of overload relay is through detecting; judge and time-delay; send action command and give coil 8A; coil 8A produces an anti-magnetic opposite with permanent magnetism power; offset permanent magnetism power; this moment, permanent magnet 7 did not have magnetic force; and armature 6 loses magnetic force simultaneously; contact support 2 is done transient motion to the right in 1 effect of dropout spring, and supports 2 to constitute the normally closed auxiliary contact 3 of one with contact; normally open contact 4; armature 6 is synchronized with the movement in company with contact, and normally closed auxiliary contact 3 is opened behind the motion certain distance; and normally open contact 4 closures; disconnect main circuit, fault is terminated, and motor is protected.Because main circuit disconnects, the anti-magnetic that coil 8A produces also disappears thereupon.
In the time of maybe will working on after the main circuit fault is got rid of, reset button is equipped with at the interface structure M place in the contact support 2.Drive, be subjected under action of reset spring and permanent magnet 7 suction when relay is subjected to reset button, armature 6 and permanent magnet 7 closures, the normally closed interlock closure, normally open contact is opened, and main circuit can be reworked, and arrives this, and actuating mechanism is finished an actuation cycle.
