Description
Technical field
The utility model is related to a kind of Standard type breaker, particularly a kind of one or two fusions Standard type vacuum circuit breaker
Device.
Background technology
National grid is to make " safe and reliable, fusion is efficient " for technical goal, using demand as guide, is detected as ensureing,
Pole-mounted circuit breaker in being transformed for distribution network construction, spirit is exchanged according to Overall Design Standards, functional module independent, equipment
The thinking of activation, preferential telesignalling dithering, the compatibility of a second interface and the autgmentability for solving to face in Distribution Automation Construction,
Terminal increase newly line loss acquisition function the problems such as, it is proposed that pole-mounted circuit breaker should set high accuracy, the voltage sensor of wide scope and

Road device will configure electronic type phase current sensor, zero sequence current sensor and voltage sensor.
The vacuum circuit breaker of China's prior art has " common box type " and " column support type " two kinds of structures.
Common box type structure is that the three-phase of breaker is placed in the casing of closing, and what is had in case fills SF6 gases, and what is had installs additional
Insulating barrier, fills dry air.Due to SF6Gas is one of gas with greenhouse effects, therefore fills SF6The structure of gas is dirty
Contaminate environment；Install insulating barrier additional, fill the hidden danger that the structure of dry air has gas leakage condensation to cause dielectric strength to reduce.Common box type knot
The disadvantage of structure is：Casing is big, and quality weight not environmentally, is not easy to install and use on post.If installing phase current additional simultaneously in case
SF6 gases will be filled in sensor, zero sequence current sensor and voltage sensor, case, not environmentally；If do not filled SF6 gases, casing
It will increase, quality is aggravated.It is as limited in do not increased the space in casing, case, cause the electric clearance of voltage sensor itself very
It is small.Although in case increase insulating barrier and fill dry air can not all solve voltage sensor itself electric clearance and creep distance it is small
The problem of, once dry air is revealed, dielectric strength declines with the generation of condensation, reliability reduction.
Column support type structure is in order to overcome the shortcoming of common box type structure to take out the three-phase of breaker from casing, altogether mounted in one
On individual outer casing stand, though the problem of this structure solves inflation and quality weight in case, enclosure can not set phase current
Sensor, zero sequence current sensor and voltage sensor.Such as by phase current sensor, zero sequence current sensor and voltage sensor
Housing exterior is arranged on, it is overall at random, increase mounting bracket, volume is increased, and quality is aggravated, led while can also increase exposed connection
Line and exposed electric connecting point, occur in that unsafe factor, it is impossible to reach the non-maintaining purpose of vacuum circuit breaker, this is also
People thirst for the technical barrier solved always.The column support type vacuum circuit breaker on outdoor lamppost configuration phase current mutual inductor of prior art
When, there is drainage the secondary lead wires of phase current mutual inductor and the contact position of shell, it is impossible to reach one or two fusion pillars of state's net
The overall purpose for meeting IP65 of formula switch.With the miniaturization of column support type vacuum circuit breaker on outdoor lamppost, prior art branch
After the miniaturization vacuum circuit breaker on outdoor lamppost configuration phase current mutual inductor of pillar, the secondary lead wires of phase current mutual inductor can not be from
Shell is introduced without handle side, is such as introduced from handle side, and the rotating shaft of operation handle is lengthened, complicated.
The content of the invention

Vacuum circuit breaker, solves column support type vacuum circuit breaker on outdoor lamppost configuration phase current sensor, zero sequence current sensor and electricity
Pressure sensor is integrally at random, increases mounting bracket, and volume is increased, the problem of quality is aggravated；Column support type pole vacuum is solved to break
Road device configuration phase current sensor, zero sequence current sensor and voltage sensor increase exposed connecting wire and exposed electrical connection
Point, occurs in that unsafe factor, it is impossible to reach the problem of vacuum circuit breaker on outdoor lamppost is non-maintaining；Solve prior art pillar
The problem of lead and casing junction intake after formula vacuum circuit breaker on outdoor lamppost configuration current transformer；Solve column support type family
The interphase of outer vacuum circuit breaker miniaturization rear casing can not introduce Current Transformer Secondary pin problem；Solve manufacture
In secondary lead wires can not position the problem of can not being stripped with core rod；Solve column support type vacuum circuit breaker on outdoor lamppost one or two times
People thirst for the technical barrier of the miniaturization solved after fusion.
