Abstract
An energy-saving permanent-magnet relay is composed of permanent magnet, fixed and moving magnetic conductors, coil, moving contact unit, static contact unit, guide track, connecting rod and casing through assembling and conneclting. Its working method features that the electromagnetic field and permanent-magnet field act on each other and the magnetic fields at left and right sides are intensified or weakened to be in different stable states. Its advantages are low energy consumption, no noise and vibration, no spark and long service life.
Description
(1) technical field:
The present invention is energy-saving permanent-magnet relay and method of work thereof, belongs to electrical apparatus technology and products thereof.
(2) background technology:
Existing various types of relay---as alternating-current trigger, magnetic starter etc., when operation, all must there be electric current to pass through coil, therefore, all want the more electric energy of loss and all can produce low frequency (100Hz) noise, the contact mechanism of relay all has microvibration, make the contact be easy to sparking and damage, the life-span short or work unreliable.
(3) summary of the invention:
Purpose of the present invention be exactly for overcome and solve existing relay exist power consumption many, produce that noise, contact mechanism easily vibrate, easily sparking damages, work is unreliable, the shortcoming and the problem of life-span weak point etc., research, invention, design are a kind of except that need the few electric energy of consumption in the node switching process, not power consumption fully when the work operation, noiselessness, contact mechanism friction phenomenon, so energy-saving permanent-magnet relay and method of work thereof not fragile, the life-span speciality.
The present invention realizes by following technical proposals: the structure of energy-saving permanent-magnet relay and course of work schematic diagram are as shown in Figure 1, it is by permanent magnet 1, fixedly magnetic conduction iron 2, motion magnetic conduction iron 3, magnetic conductor 4, coil 5, moving contact mechanism 6, fixed contact mechanism 7, guide rail 8, connecting rod 9, shell 10 mutual group loads connect and constitute, its mutual rigging position and annexation are: fixedly magnetic conduction iron 2 constitutes by silicon steel sheet is superimposed, it and permanent magnet 1 closely contact connection mutually; Permanent magnet 1 closely contacts with the magnetic conductor of being made by ferromagnetic material 4 and is connected; Magnetic conductor 4 be slidably to contact to be connected by the superimposed motion magnetic conduction iron of making 3 of silicon steel sheet, two ends, the left and right sides can arbitrarily swing up and down; Motion magnetic conduction iron 3 when an end and connecting rod 9 are slidingly connected, the just unsettled disconnection of the other end; Connecting rod 9 is slidingly connected for 6 one-tenth with moving contact mechanism; Moving contact mechanism 6 is limited in the vertical scope by guide rail 8 and moves up and down; When the upper contact of rest(ing) contact mechanism 7 was connected, the lower contact of fixed contact 7 mechanisms just was in off-state, otherwise promptly right; Whole permanent-magnet relay mechanism is installed in the shell 10, and the power supply lead wire of coil is drawn by the wire guide of reserving on the shell 10.
The method of work of this energy-conservation permanent-magnet relay is as follows: the key of its method is " electromagnetism and permanent-magnetic field interact ", specifically: permanent magnet 1 constitutes the closed-loop path by magnetic circuit A, makes motion magnetic conduction iron 3 the right tightly constitute a kind of steady state of motion with fixing magnetic conduction iron 2 is tightly closed; This moment, motion magnetic conduction iron 3 left sides were by magnetic circuit B, because of the excessive magnetic field intensity of air gap a little less than, be in the bigger position of fracture always; When need switching node state, only need to give coil 5 instantaneous energisings to produce additional magnetic circuit C, magnetic circuit C and magnetic circuit A are cancelled out each other, make the right field weakening, and magnetic circuit C and magnetic circuit B addition make magnetic field, the left side obtain bigger reinforcement, so motion magnetic conduction iron 3 left side closures, the right is left and is formed a fracture, and at this moment additional power source disconnects, just is in another steady-working state again.
The present invention compares with prior art equipment has following advantage and beneficial effect: (1) the technology of the present invention is to become mechanical movement by electromagnetism, utilize the principle of the inventive method, can be generalized to the power field very widely that is applied to, it can make a lot of dynamic power machines be improved, therefore has tangible creativeness, outstanding advantage is compared with prior art arranged, bigger breakthrough is arranged, very considerable economic and social benefit is arranged; (2) permanent-magnet relay of the present invention removes in its node transfer process, and coil need power up, and needs outside the loss energy seldom, in the work running, additional power source can be removed fully, but this energy-conservation permanent-magnet relay safe and reliable operation still; (3) has no noise in the energy-saving permanent-magnet relay work running of the present invention; (4) contact mechanism of this energy-conservation permanent-magnet relay does not have no oscillation phenomenon, and is therefore fragile, the life-span is longer.
(4) description of drawings:
Below Figure of description is further specified as follows: Fig. 1 is that the structure of this energy-conservation permanent-magnet relay constitutes and course of work schematic diagram.Among the figure: the 1st, permanent magnet, the 2nd, fixing magnetic conduction iron, the 3rd, motion magnetic conduction iron, the 4th, magnetic conductor, the 5th, coil, the 6th, moving contact mechanism, the 7th, fixed contact mechanism, the 8th, guide rail, the 9th, connecting rod, the 10th, shell.
(5) concrete execution mode:
The applicant thinks and realizes that optimal way of the present invention can be as follows: (1) by shown in Figure 1, design, processing and manufacturing or choose each parts, and for example: permanent magnet 1 can be selected Nd-Fe-B permanent magnetic material type for use; Fixedly magnetic conduction iron 2 can select that 0.5 silicon steel sheet is folded to be made for use; Motion magnetic conduction iron 3 can select for use the superimposed compacting of silicon steel sheet and all-purpose adhesive or epoxy resin to form, and specification can be 0.5 silicon steel sheet; The magnetic conductor 4 optional electrical pure irons of using; Coil 5 is optional to be made skeleton with bakelite or engineering plastics and forms with the copper wire coiling that is coated with insulating varnish outward; Moving contact mechanism 6, fixed contact mechanism 7, guide rail 8, connecting rod 9 all can be ordered the ready-made parts that close specification by relay manufacturer, and shell 10 is optional injection molded with engineering plastics.The technical indicator parameter that certain whole energy-saving permanent-magnet relay can propose to be correlated with,, order customized to existing relay manufacturer.
