Description
Technical field
The present invention relates to it is a kind of for low voltage protection device for electrophonic, tool there are two opposite contact chip blocking mechanism, wherein
Rotatable handle is arranged between contact chip, handle is in effective connection status via toxoplasm and roller.
Background technique
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, electricity or mechanical switch unit is suitable for manually switching power consumption part according to operating status, and for maintaining
It is isolated when operation or when having change to equipment by equipment with power grid security.Electric switch unit is usually transported in an electromagnetic manner
Row.
That is, this kind of switch unit is high technology content, has for motor, conducting wire, transformer and generator
Integrated protection electric switch device.They are used in the lower functional part of switching frequency in daily life.This kind of switch
Unit is also adapted to overload protection other than 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.The conductor for each having electric current to flow through more or less acutely generates heat.This fever depends on current strength and electric current herein
The proportionate relationship of conductors cross, i.e., so-called current density.Current density cannot be excessive, because otherwise passing through excessively high fever
May make that conductor insulation is allowed to burn or may cause fire.In order to protect electric equipment, being damaged property does not influence, and switch is single
Member is used as overcurrent protection.
There are two be separated from each other trigger mechanism working, for overload protection and short-circuit protection to breaker tool.This two
A 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.
Well known switch unit 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 unit also has the first contact with ampere wires.It is connecing
In the state of logical, the fixed contact of the contact switch unit of movable switch member.It is movable under short-circuit state
The electric contact of switch member is loosened from fixed contact, thus interruptive current.Herein, movable switch member is from fixed contact
It loosens.
Breaker is other than meeting their defencive function as overload and short-circuit trigger member, as having already mentioned above
As, it is also responsible for specification ground off and on motor.In order to prove these functions, breaker is allowed 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, which is jumped, completes to interrupt double times of three current paths in function, these three current paths are connected with a movable electric bridge respectively
Form with two movable contact sites and two fixed contact sites exists.
In order to realize this function, via the mechanical device of manual operation, with operating element, blocking mechanism and operational chain
Form opens the contact assembly being made of contact sliding block and movable electric bridge.This unlatching is complete by so-called quick-make
At.Herein, only after blocking mechanism has be turned on, three contact systems can just be held by a mechanical device
It opens.Now, spring memory determines movement of the contact system when connecting in the form of contact load spring.
After electric bridge impinges upon on fixed switch piece, contact sliding block accelerates, until it is repelled on stopper section.Pass through
The rebound of contact sliding block and the kinetic energy thus obtained, cause contact system to reopen.This electric current in current path is simultaneously
It may cause welding in the case where promotion.
In the breaker with low rated current, the function of quick-make is unnecessary.However, for production procedure
For it is desirable that the blocking mechanism when this breaker can be to install additional by the measure on simple building mode
The form fit on quick-make system of process.
Summary of the invention
