Description
Technical field
The present invention relates to a kind of breakers, and in particular to a kind of large capacity breaker of plastic casing is applicable to AC and DC
In electric system.
Background technique
Breaker is the electric current referred to close, carry and cut-off under normal loop condition and can close, when defined
Interior carrying and the switching device for cut-offfing the fault current under abnormal loop condition.Breaker is generally by contact system, arc extinguishing system
System, operating mechanism, buckle releaser and plastic shell etc. are constituted, and can be divided into frame-type circuit breaker by structure point and (also be made universal disconnected
Road device) and mold cased circuit breaker.
Frame-type circuit breaker is divided into fixed and drawer type by the installation mode of connection, for stationary frame breaker, breaks
Road device ontology (including plastic shell, contact system, arc quenching system, operating mechanism and buckle releaser etc.) is fixed on metallic support,
It is fixed on when use on horizontal mounting plate (or being horizontally mounted frame), overall dimensions are smaller than open frame circuit breaker;Drawer type frame
Breaker body 1 is mounted in drawer chassis 2 by breaker, as shown in Figure 1, can by shake into mechanism by breaker body 1 shake into
Or drawer chassis 2 is shaken out, convenient for the maintenance and test of breaker, but open frame circuit breaker volume is big, weight weight, and large capacity is taken out
The weight of drawer formula breaker, drawer chassis 2 is even suitable with the weight of breaker body 1.Therefore, although frame-type circuit breaker has
Have the advantages that short circuit breaking capacity is high, KA Rms is high, but its overall dimensions is big, weight weight.
Breaker of plastic casing uses plastic insulation as the shell of breaker, contact, arc-chutes, buckle releaser and operating system etc.
It is fitted into plastic shell, it is easy to accomplish phase insulation and be isolated with electric conductor.Breaker of plastic casing has compact-sized, volume
It is small, it is light-weight the features such as, but its bear short circuit current ability is low, intelligence degree is lower than frame-type circuit breaker, be often used for
Rated current is in 630A low capacity circuit below.
Summary of the invention
In view of this, the present invention provide it is a kind of have the characteristics that the breaker of plastic casing of frame circuit breaker, which has modeling
Case circuit breaker advantage small in size, light-weight, compact-sized, while it is high, in short-term also to have frame circuit breaker short circuit breaking capacity
It is resistant to the high advantage of electric current.
The present invention provide a kind of breaker of plastic casing with frame-type circuit breaker include: fixed breaker ontology,
Line bank and insulation back shroud before fixed plate;
The structure of the fixed breaker ontology is identical as frame-type circuit breaker body construction, comprising: plastic shell is set
The contact system and arc quenching system inside plastic shell are set, electronic type release, the operation of plastic shell front end face are set
Mechanism and electronic energy storage mechanism;
Line bank before fixed plate is set on the rear end face of the plastic shell, and line bank is defeated before the fixed plate
Enter end and output end to draw to the upper and lower part of the plastic shell respectively;
The installation insulation back shroud on the rear end face of the plastic shell.
The breaker of plastic casing is installed using suspension type, and the insulation back shroud is as suspension installation part.
In addition, the present invention, which provides another kind, has the characteristics that the breaker of plastic casing of frame circuit breaker, comprising: plug in circuit breaker
Ontology, insulation back shroud and plug-in type erecting bed;
The structure of the plug in circuit breaker ontology is identical as frame-type circuit breaker body construction, comprising: plastic shell is set
Set contact system and arc quenching system inside plastic shell, electronic type release that plastic shell front end face is set, operation
Handle and electronic energy storage mechanism;
The installation insulation back shroud on the rear end face of the plastic shell;
The leading-out terminal of the plug in circuit breaker ontology is the plane plug for stretching out the insulation back shroud;
Line bank is arranged in position corresponding with the plane plug on the plug-in type erecting bed;
The plug-in type erecting bed is docked with the rear end face of the plug in circuit breaker ontology, make the line bank with it is described
The connection conducting of plane plug, and be detachably connected between the plug-in type erecting bed and the plug in circuit breaker ontology.
The plug-in type erecting bed is wiring erecting bed after sheet insertion mode, enables wiring erecting bed and institute after the sheet insertion mode
The interface for stating plug in circuit breaker ontology is its front end face, the rear end face and plane of wiring erecting bed after the sheet insertion mode
The corresponding position of plug is provided with line bank after sheet insertion mode, and the plane plug on the plug in circuit breaker ontology passes through insertion
Line bank connection is led after the sheet insertion mode of wiring erecting bed rear end face after jack and sheet insertion mode after formula plate on wiring erecting bed
It is logical.
The plug-in type erecting bed is wiring erecting bed before sheet insertion mode, enables wiring erecting bed and institute before the sheet insertion mode
The interface for stating plug in circuit breaker ontology is its front end face, and the front end face setting of wiring erecting bed is inserted before the sheet insertion mode
Enter line bank before formula plate, line bank input terminal and output end are installed to wiring before the sheet insertion mode respectively before the sheet insertion mode
It draws the upper and lower part of platform;Plane plug on the plug in circuit breaker ontology is directly pacified with wiring before the sheet insertion mode
Line bank connection is connected before filling the sheet insertion mode of platform front end face.
The utility model has the advantages that
1600A frame-type circuit breaker is optimized in the breaker, removes metallic support and drawer chassis, and using suspension
Formula mounting means devises and installs two kinds of mounting means using fixedly mounted and plug-in type by plug-in type erecting bed, Gu
Fixed pattern generally uses the mode of connection before plate when installing, and the mode of connection after wiring or plate can be used before plate in plug-in type when installing.Therefore
The present invention has the feature of breaker of plastic casing;Simultaneously because the ontology of the breaker is frame circuit breaker, using frame open circuit
The electronic type release of device carries electronic energy storage mechanism, operating mechanism, contact system and arc extinguishing system with frame circuit breaker
System, therefore have the advantage that frame circuit breaker short circuit breaking capacity is high, KA Rms is high.And the breaker of the structure
Have preferable maintainability, but reduce volume than frame circuit breaker and alleviates weight.
