Description
Technical field
The present invention relates to a kind of magnetic latching relay, more particularly to a kind of magnetic holding relay that can resist short circuit current flow
Device.
Background technology
The structure of existing magnetic latching relay is made up of magnetic circuit system, contact system, pushing mechanism and pedestal.Magnetic circuit system
Typically it is made up of the magnetic circuit of two almost symmetries, including static magnetic conduction body component, movable magnetic conduction body component and coil, contact system
Including moving spring part, quiet spring part, pushing mechanism typically taken on by pushing block, pushing mechanism be connected to movable magnetic conduction body component with
Between dynamic spring part.The logical direct impulse voltage of relay coil, magnetic circuit system work, and pushing block promotes dynamic spring part, makes contact
Contact, the actuating of relay, the logical reverse impulse voltage of coil, magnetic circuit system work, and pushing block promotes dynamic spring part, make contact break
Open, relay involution.
Magnetic latching relay main application fields are electric-power metering, and major function is switch and metering.With countries in the world
Deepening continuously for electric network reconstruction, as the fried table of the ammeter of short circuit current flow initiation, the case that catches fire happen occasionally, has caused huge
Human safety issues and property loss problem.In this context, world Ge great Utilities Electric Co.s, ammeter enterprise launch respectively related mark
Accurate or reference industry standard, with its specification electric energy meter power magnetic latching relay opposing short circuit current flow ability, improves intelligence electricity
The safety of table operation.In order to ensure personal safety, electrical equipment safety, be required to magnetic latching relay have bear with connect short
The function of road electric current.According to operation of power networks feature and based on to the person, equipment safety consideration, magnetic latching relay opposing short circuit is electric
Stream has three kinds of operating modes, specific as follows：
Operating mode one：Ammeter front end (upstream electrical network) short circuit, is characterized in that the magnetic latching relay closing of contact (ammeter combined floodgate shape
State), short circuit current flow is larger, and short circuit current flow now is referred to as " safety tolerance short circuit current flow ", it is desirable to which magnetic latching relay bears short
During the electric current of road or after bearing short circuit current flow " do not explode, not on fire, without splash ".
Operating mode two：Ammeter rear end (downstream electrical network) short circuit, is characterized in that the magnetic latching relay closing of contact (ammeter combined floodgate shape
State), short circuit current flow is less, and short circuit current flow now is referred to as " function tolerance short circuit current flow ", it is desirable to which magnetic latching relay bears short
After the electric current of road " function is normal ".
Operating mode three：Ammeter rear end (downstream electrical network) short circuit, is characterized in that magnetic latching relay contact disconnects that (ammeter is operated a switch shape
State), short circuit current flow is less, and short circuit current flow now is referred to as " function connection short circuit current flow ", it is desirable to which magnetic latching relay is connected short
After the electric current of road " function is normal ".
Under three kinds of operating modes, short circuit current flow difference in size is larger, such as IEC62055-31 standard UC2 grades " safety tolerance short circuit
Electric current " is 4.5KA, is 1.8 times of " function tolerance short circuit current flow " or " function connection short circuit current flow " 2.5KA；UC3 grades " peace
Full tolerance short circuit current flow " is 6KA, is 2 times of " function tolerance short circuit current flow " or " function connection short circuit current flow " 3KA；And for example
ANSI C12.1 standard 200A rated current grades " safety tolerance short circuit current flow " peak value 24KA, is " function tolerance short circuit current flow "
3.4 times of peak value 7KA.

The overall dimensions of big product, the power consumption for increasing coil control section, it is impossible to meet client to product design miniaturization and low-power consumption
Requirement, meanwhile, product cost anxious poly- can rise, and cause product market competition ability to decline.
The design of existing magnetic latching relay mainly utilizes Lorentz force principle, using one times of short circuit current flow can movable contact spring
(movable contact spring) upper electromagnetic force for producing is resisting the electrodynamic repulsion force that short circuit current flow is produced between dynamic and static contact.Concrete scheme is designed
When, the distance between short circuit current flow size and two reeds is closely related, resists effect and the reed deflection (rigidity) of short circuit current flow
Closely related.Due to " safety tolerance short circuit current flow " differ with " function tolerance short circuit current flow " or " function connection short circuit current flow " compared with
Greatly, meet the design of " safety tolerance short circuit current flow ", differ surely compatible " function tolerance short circuit current flow " or " function is connected
Short circuit current flow ", vice versa.Equally, the design of UC3 standards not necessarily backward compatible UC2 standards are met.
The main technological route for solving magnetic latching relay opposing short circuit current flow function in prior art has two kinds, the first
It is " to produce when the electromagnetic force produced when contrary with the movable contact spring sense of current using lead-out tablet is to resist dynamic and static contact by high current
Raw electric power ", as disclosed by Chinese patent application CN200710008565.4.Second is " using electricity in shunt circuit
The identical generation electromagnetic attraction in stream direction, increases the pressure between dynamic and static contact " realize opposing short circuit current flow function, such as Europe specially
Disclosed by profit application EP1756845A1.Either that is a kind of, be using one times of short circuit current flow flow through can movable contact spring (i.e.
Movable contact spring) and can movable contact spring lead-out tablet (move spring lead-out tablet), and can the upper electromagnetic force for producing of movable contact spring (i.e. movable contact spring) come
The electrodynamic repulsion force that opposing short circuit current flow is produced between dynamic and static contact, therefore, it is impossible to meet improve dynamic and static contacts closed forces
Require, and latter adopts parallel circuit, the dynamic and static contact quantity that need to be doubled, also result in product cost increase.
