Description
Technical field
The utility model relates to electricapparatus interlocking technology field, especially relates to a kind of electric operating breaker of plastic casing and drawout cubicle laminate interlocking device.
Background technology
At present, if while electrically operated breaker of plastic casing being installed in drawer loop, electrical interlock or Warning Sign must be set, prevent warm swap insulating contact, way was in the past:
1, drawer unit for " test position " primary circuit without isolation fracture: because of in " service position ", " open position " and " test position " drawer unit relative position does not change, three positions that are in operation are the same, and in " test position " in " withdrawn position " process, one, secondary plug almost separates simultaneously, therefore, be difficult to utilize linear quadratic control to prevent charged separation insulating contact, as adopt position switch (test position switch) to control decompression coil method, to cause drawer unit extracting out after cabinet, cannot manual operation breaker of plastic casing due to decompression coil losing electricity, and cost is high, at present, majority is to adopt warning prompt method to realize anti-error.
2, the drawer unit without isolation fracture for " test position " primary circuit: because changing at " service position ", " test position " and " isolated location " drawer unit relative position, can utilize position switch control decompression coil or utilize position switch control motor-operating mechanism mode to realize locking, but cost is high, there is imperfection factor simultaneously.As adopt the former to realize locking, and cause drawer unit extracting out after cabinet, cannot manual operation breaker of plastic casing due to decompression coil losing electricity; If adopt the latter to realize locking, because the intrinsic opening time of motor-operating mechanism is longer, if fast drawer unit is moved on to " test position " from " service position ", may there is not separating brake and segregation phenomenon of disposable separating plug of breaker of plastic casing.
Summary of the invention
It is a kind of simple in structure that the purpose of this utility model is to provide, and easy to operate electric operating breaker of plastic casing and drawout cubicle laminate interlocking device solve the technical problem that existing drawer unit and circuit breaker interlocking exist.
For achieving the above object, the utility model adopts following technical scheme:
A kind of electric operating breaker of plastic casing and drawout cubicle laminate interlocking device, comprise drawer unit, drawer unit is arranged on draw out switchgear cashier's office in a shop, in drawer unit, be provided with electric operating circuit breaker, described circuit breaker end is provided with circuit breaker interlocking device, circuit breaker interlocking device adopts plug in circuit breaker interlocking device, plug in circuit breaker interlocking device front end is provided with screens post, be fixed on draw out switchgear cabinet laminate the interlocking device coordinating with plug in circuit breaker interlocking device is housed, interlocking device is provided with first line of a couplet card locking hole.
Described interlocking device is arranged on the laminate of drawer unit.
Interlocking hole clipping front end in described interlocking device is provided with the prerotation vane of screens post, and prerotation vane front end has slip fillet.
The panel front of described drawer unit is provided with drawer unit operating mechanism.
A kind of electric operating breaker of plastic casing that the utility model provides and the gain effect of drawout cubicle laminate interlocking device are: with reference to plug-pull type breaker interlock method, design mechanical lock realizes moulds shell switch and drawout cubicle laminate interlocking, ensure that drawer unit makes to mould shell switch separating brake in the time will leaving " service position ", install the device that the interlocking device of plug-pull type breaker and the interlocking device of circuit breaker coordinate additional, be installed on laminate, make to coordinate with it the object that reaches interlocking, meet five anti-requirements, fail safe is improved.

embodiment:
In order to make juror can the object of the utility model, feature and function be had further and be understood, below in conjunction with accompanying drawing, the utility model be further illustrated:
Refer to shown in Fig. 1-6, it is structural representation of the present utility model, the utility model is about a kind of electric operating breaker of plastic casing and drawout cubicle laminate interlocking device, comprise drawer unit 1, drawer unit 1 is arranged on draw out switchgear cabinet 2, in drawer unit 1, be provided with electric operating circuit breaker 3, described circuit breaker 3 ends are provided with circuit breaker interlocking device, circuit breaker interlocking device adopts plug in circuit breaker interlocking device 4, plug in circuit breaker interlocking device 4 front ends are provided with screens post 42, be fixed on the interlocking device 6 coordinating with plug in circuit breaker interlocking device 4 is housed on draw out switchgear cabinet laminate 7, interlocking device 6 is provided with first line of a couplet card locking hole 61.Interlocking device 6 is arranged on the laminate 7 of drawer unit.Interlocking hole clipping 61 front ends in interlocking device 6 are provided with the prerotation vane 62 of screens post 42, and prerotation vane 62 front ends have slip fillet 63.Panel 5 fronts of drawer unit 1 are provided with drawer unit operating mechanism 9.
Circuit breaker, as needed breaking-closing operating, must make " interlocking device on circuit breaker " in Spontaneous release state.
When drawer unit is during in service position, " interlocking device on circuit breaker ", in Spontaneous release state, circuit breaker can carry out breaking-closing operating like this.As shown in Figure 3.
In the time that drawer unit leaves service position, " interlocking device on circuit breaker ", in Interlock Status, makes breaker open operation.As shown in Figure 4, guarantee that drawer unit is before a plug-in unit separates, breaker open operation.
In the time that drawer unit arrives separation point position, " interlocking device on circuit breaker ", in Spontaneous release state, circuit breaker can carry out breaking-closing operating like this.As shown in Figure 5.
Certainly, these are only the utility model preferred embodiments, not limit the scope of application of the present utility model with this, therefore, allly in the utility model principle, make equivalent change and all should be included in protection range of the present utility model.
