Description
Technical field
It the utility model is related to a kind of vacuum circuit breaker, and in particular to a kind of outdoor AC prepayment metering type vacuum circuit breaker
Device.
Background technology
At present, in high-tension circuit, typically measured with electromagnetic transformer such as Current Transformer come measuring circuit parameter
High-tension current, voltage is measured with voltage transformer, power supply state is monitored by measured Current Voltage.It is existing
Measurement apparatus and switching device are separated type, install the two respectively in construction, and this increases not only workload and work are strong
Degree, nor beneficial to the unified inspection to device with safeguarding.So as in the market, there have been the high pressure with function of measuring is true
Empty breaker, still, most of existing current prepayment vacuum breaker structure type are all installed in true metering transformer
The box house of empty breaker, once metering transformer is problematic, it is necessary to and take whole vacuum circuit breaker apart, not only waste time and energy,
And because the internal structure of vacuum circuit breaker is narrow and small, the insulation measures hidden danger not in place for turning into maximum, and vacuum short circuit
Volume is not only high but also big, carries or installs and be particularly inconvenient.
The content of the invention
The defects of the purpose of this utility model is to overcome prior art, there is provided a kind of simple in construction, install convenient, performance
Reliable and stable outdoor AC prepayment metering type vacuum circuit breaker.
To achieve the above object, the utility model uses a kind of outdoor AC prepayment metering type vacuum circuit breaker, including
Casing, the operating mechanism being arranged in casing, three insulation columns being arranged on casing, corresponding three absolutely on described casing
Current transformer is provided with the side of edge pillar, is corresponded on described casing and is provided with meter at the opposite side of three insulation columns
Transformer is measured, is connected respectively by a connecting plate between described metering transformer and three insulation columns, the metering mutual inductance
Device is respectively arranged with three disconnecting switch with isolating between main shaft for operating mechanism, and described disconnecting switch includes being arranged on casing
On insulator, terminal plate on the insulator, the connecting lever bent plate being rotatably arranged on terminal plate are set, linked with connecting lever bent plate
The upper contact being arranged at the contact knife piece of setting, corresponding contact knife piece in metering transformer, the insulation set with isolating main shaft linkage
Pull bar, one end of described contact knife piece are connected on one end of connecting lever bent plate, are provided with the other end of contact knife piece and upper contact
The movable contact being in contact, the other end of described connecting lever bent plate are connected on the upper end of insulated tension pole.
Said structure has the beneficial effect that：The outdoor AC prepayment metering type vacuum circuit breaker is by metering transformer part
It is completely separable with breaker portion, interacting between metering transformer part and breaker portion is avoided, and will metering
Transformer part and breaker portion set are integral, shorten installation workload, so as to the outdoor AC prepayment metering type
Vacuum circuit breaker has the advantages of simple in construction, install convenient, stable and reliable for performance.
Especially, the cross sectional shape of described movable contact is in Long Circle.Movable contact is arranged to Long Circle structure, increased
The contact area of movable contact and upper contact, advantageously reduce contact resistance, improve electric conductivity, ensure that breaker work
Stability.
Especially, multiple lifting links are distributed with the upper surface of described casing.By being provided with lifting on casing
Link, consequently facilitating the carrying and installation of the vacuum circuit breaker.
Especially, wiring air plug is provided with the side wall of described casing.Wiring air plug is provided with casing, so as to just
In the wiring of the breaker.
Brief description of the drawings
Fig. 1 is the utility model embodiment stereogram.
Fig. 2 is the utility model embodiment front view.
