Description
Technical field
The present invention relates to a kind of high voltage switchgear, refer in particular to the intelligent pole vacuum circuit breaker in a kind of open air.
Background technology
In high voltage electrical apparatus technical field, outdoor AC high-voltage vacuum circuit-breaker (hereinafter to be referred as circuit breaker) is the outdoor electricity distribution equipment of rated voltage 12kV, three-phase alternating current 50Hz.Be mainly used in and cut-off, close the load current, overload current and the short circuit current that close in the electric power system.Be applicable to and do protection and control in transformer station and the industrial and mining enterprises' distribution system, more be applicable to the place of rural power grids, city overhead transmission line and frequent operation.It is the requisite terminal equipment of intelligent grid.Satisfy the requirement of various distribution switching stations, transformer station simultaneously.Have compact conformation, long-life, non-maintaining, characteristics that volume is little.Belong to a kind of control and protection electrical equipment.(3.6kV～24kV) the gas-filled type high voltage switchgear is the high voltage switchgear of new generation that last century, the nineties was risen to middle the pressure, and little with its volume, antipollution obtains users' approval very soon, and application surface is more and more wider.Most domestic producer still adopts the technology of the external 1980s at present, and technical parameter still rests on the level of rated current 630A, specified drop-out current 20KA, and technology falls behind in addition, and processing, assembling, debugging all are difficult to control than trouble, quality.Be difficult to adapt to the requirement of large-capacity user and the growth requirement of following intelligent electrical network simultaneously.
Summary of the invention
The objective of the invention is to overcome above-mentioned defective; Adopt technological, the advanced on-line monitoring technique of modularized design and pole, a kind of bigger capacity rated current 1250A, rated short circuit drop-out current 25KA are provided, and meet the novel outdoor pole vacuum circuit breaker that satisfies existing electric power system requirement and intelligent demand.
The objective of the invention is to realize like this: the intelligent pole vacuum circuit breaker in a kind of novel open air; Its improvements are: it comprises, inflates housing and operating mechanism chamber; Be sealed with the three-phase high-voltage major loop in the inflation housing; It mainly by about bus-bar duct, solid sealed pole of vacuum circuit breaker, operating axis, the insulated tension pole arranged forms, three coordinate front and rear row row, vacuum circuit-breaker operating mechanism are loaded on the outside of inflating housing through a transmission operating axis, the outside adds seal cover.Operating mechanism is sealed in the gas equally, does not receive the influence of external environment condition.
Said vacuum circuit-breaker internal bus and circuit breaker moved end be equipped with the airtight table of temperature sensor and the band Alarm contactor of wireless telecommunications, through control of intelligent terminal, but the actual motion state of remote monitoring and remote-control circuit breaker.Make it to reach fully intelligentized requirement.
Be sealed with vacuum interrupter in the said solid sealed pole of vacuum circuit breaker, the quiet end of vacuum interrupter is electrically connected electric outside line, and the moved end is electric to be flexible coupling to go out wire conduit with the other end and link to each other through one; Said pole vacuum interrupter moved end links to each other with operating axis through the insulated tension pole that is provided with, and operating axis is through linking with breaker operation mechanism.
Every phase can be installed two groups of current transformers in the said inflation shell chamber, and one group can be used as metering and protection usefulness, and another group can be used as conventional control of circuit breaker and protection power supply.Solve before circuit breaker and need establish a difficult problem that controls power supply in addition.
Than pole vacuum circuit breaker before; Beneficial effect of the present invention is that the critical piece vacuum interrupter of vacuum circuit-breaker is a pole type, has reduced the workload in the assembling process, has improved control of product quality effectively; Shortened the production manufacturing cycle.The each several part modularity is stronger in the circuit breaker; Not only be convenient to the digital control processing manufacturing of each intermodule; Also can effectively improve the interchangeability and the reliability of its parts; The world of having filled up this type product is blank, and the versatility of complete machine and standardization level are high, have satisfied the electric power system actual motion simultaneously to more jumbo requirement.
Description of drawings
Below in conjunction with detailed description of the drawings concrete structure of the present invention
Fig. 1 is a side sectional view of the present invention;
Fig. 2 is an appearance structure sketch map of the present invention;
Fig. 3 is a sectional top plan view of the present invention.
In the accompanying drawing, 1-inflation housing, 2-cable duct tube, 3-insulating support, 4-conduction is flexible coupling, 5-vacuum pole, 6-current transformer, 7-operating axis, 8-insulated tension pole, 9-mechanism seal cover, 10-secondary distribution be with aviation socket, 11-electrical spring operating mechanism.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the invention is set forth in detail.
Like Fig. 1, Fig. 2, shown in Figure 3; The present invention relates to the intelligent pole vacuum circuit breaker in a kind of novel open air; It comprises inflation housing 1, and electrical spring operating mechanism 11, cable duct tube 2, insulating support 3, conduction are flexible coupling 4, vacuum pole 5, current transformer 6, operating axis 7, insulated tension pole 8, mechanism's seal cover 9, secondary distribution be with aviation socket 10.
