Description
Technical field
The present invention relates to a kind of blocking mechanism for low voltage protection device for electrophonic, with two opposite contact chips, wherein,
Rotatable handle is arranged between contact chip, handle is in effective connection status via toxoplasm and roller.
Background technology
Low voltage protection device for electrophonic, especially breaker are mainly used for safe shutdown in short circuit and thus protect current consuming apparatus.
In addition, electric or mechanical switch element is suitable for manually switching power consumption part according to running status, and for maintaining
Isolate during operation or when having change to equipment by equipment with power grid security.Electric switch unit is generally transported in an electromagnetic manner
OK.
That is, this kind of switch element be high technology content, have be used for motor, wire, transformer and generator
Integrated protection electric switch device.They are used in the relatively low functional part of switching frequency in daily life.This kind of switch
Unit is also adapted to overload protection in addition to short-circuit protection.
In case of a short circuit, electric switch unit safely turns off electric equipment.In be that it provides for overload safety
Protection.Each conductor for having electric current to flow through more or less acutely generates heat.This heating depends on current strength and electric current herein
The proportionate relationship of conductors cross, i.e., so-called current density.Current density can not be excessive, because otherwise passing through too high heating
It may make to allow conductor insulation to burn or fire may be triggered.In order to protect electric equipment, being damaged property does not influence, and switch is single
Member is used as overcurrent protection.
Breaker has two and is separated from each other trigger mechanism working, for overload protection and short-circuit protection.This two
Individual trigger member is connected in series.Protection work when short-circuit is undertaken by the electric trigger member almost to work immediately in time.Short
Lu Shi, electromagnetism trigger member open the blocking mechanism of breaker immediately.Before the peak that short circuit current can reach it, switch
Anchor (Schaltanker) just separates switch member.
Known switch element has the contact slide unit with contact sliding block and movable switch member.In addition, institute
Stating movable switch member also has electric contact.In addition, this kind of switch element also has the first contact with ampere wires.Connecing
In the state of logical, the fixed contact of the contact switch element of movable switch member.It is movable under short-circuit state
The electric contact of switch member releases from fixed contact, so as to interruptive current.Herein, movable switch member is from fixed contact
Release.
Breaker as overload and short-circuit trigger member in addition to meeting their defencive function, as having already mentioned above
As, with being also responsible for specification off and on motor.In order to prove these functions, breaker allows for according to product standard
Connect ten times of rated motor electric current.In order to ensure this limit load, it is necessary to allow breaker at substantially the same time and
Jump is jumped to be completed to interrupt double times of three current paths in function, and these three current paths are connected with a movable electric bridge respectively
Form with two movable contact sites and two fixed contact sites is present.
In order to realize this function, via manually operated mechanical device, with operating element, blocking mechanism and operational chain
Form opens the contact assembly being made up of contact sliding block and movable electric bridge.This unlatching is complete by so-called quick-make
Into.Herein, only after blocking mechanism has be turned on, three contact systems can just be held by a mechanical device
Open.Now, spring memory determines motion of the contact system when connecting in the form of contact load spring.
After electric bridge is impinged upon on fixed switch piece, contact sliding block accelerates, until it is repelled on stopper section.Pass through
The bounce-back of contact sliding block and the kinetic energy thus drawn, cause contact system to reopen.This electric current in current path is simultaneously
It may cause to weld in the case of lifting.
In the breaker with low rated current, the function of quick-make is unnecessary.However, for production procedure
For it is desirable that when the blocking mechanism of this breaker just can be to install additional by the measure on simple building mode
The form fit on quick-make system of flow.
The content of the invention
