Description
Technical field
The present invention relates to a kind of breaker, especially a kind of indoor fixed side fills vacuum high-pressure breaker, belongs to high pressure
Appliance field.
Background technology
Electric system is a prodigious real-time working system, and the working method of electric system has feature by oneself, and power generation becomes
Electricity, transmission of electricity, electricity consumption are completed in a flash same.It is more and more wider with the coverage area of network system, the capacity of electric power unit
Increasing, the requirement for electricity consumption is higher and higher, particular, it is important that power industry is most it is emphasised that safety, it is desirable that electric power
System can be coordinated with very complete automatic control mode.
Allow advanced control system that can finally realize control, it is important measures to be equipped with more novel breaker.Mesh
The switch elements such as preceding common indoor high-voltage vacuum circuit breaker, indoor high-voltage isolating switch and indoor hv earthing switch are to hand over
Flow the important electric elements in metal enclosed switchgear (i.e. high-tension switch cabinet).
Vacuum circuit breaker uses vacuum interrupter, using vacuum as arc extinguishing and dielectric, has high vacuum degree.When
When dynamic/static contact charges separating brake under operating mechanism effect, vacuum arc will be will produce between contact, simultaneously as the spy of contact
Different structure also will produce longitudinal magnetic field appropriate in the gap of contact, promote vacuum arc to remain diffused, and make electric arc
It is evenly distributed on contact surface burning, maintains low arc voltage, in electric current natural zero-crossing, remaining ion, electronics and gold
Belong to steam can be compound within the time of the microsecond order of magnitude or to condense upon in contact surface and shielding case, arc-chutes port it is exhausted strong
Degree is resumed quickly, achievees the purpose that disjunction to which electric arc is off.Due to controlling vacuum arc using longitudinal magnetic field, so very
Empty breaker has powerful drop-out current ability.
Pole is the necessary component of breaker, and pole generally uses following structure:Pole is at least by true
Empty arc-chutes, main conductive circuit, insulating supporting organic assembling form;The insulator of integrated sealing uses APG by epoxy resin
Technique is poured into a mould.Indoor high-voltage vacuum circuit breaker uses solid insulation structure, by vacuum interrupter, main conductive circuit, insulation
Support etc. is organically combined into an integrated solid sealed pole.Insulator is poured into a mould by epoxy resin using APG techniques, is integrated
The design of pole thoroughly avoids the mealiness aggregation of arc extinguishing chamber surface, and arc-chutes have been designed to exposed structure, no
It only ensure that high reliability, and realize miniaturization and economy.Integrated solid sealed pole can solve the environment of vacuum circuit breaker
Commpensation And Adaptation is widely used.
And also there are many operating mechanisms for permanent magnet type breaker, permanent-magnet manipulating mechanism, which includes at least, a kind of bistable magnetic circuit
Device, at least two magnetizing coils and can driven dynamic iron core, and be configured with manual switching-off device.Indoor high-voltage vacuum is disconnected
Road device adapted permanent-magnet manipulating mechanism, the mechanism utilize a kind of bistable magnetic circuit system, are driven using two magnetizing coils and move iron
Core moves to corresponding extreme position, and the magnetic field energy provided using two pieces of permanent magnets, is allowed to be maintained at extreme position.Swash
It sends out magnetizing coil one of and is allowed to generate the driving force for being more than remaining retentivity, you can keep the dynamic iron core of permanent-magnet manipulating mechanism dynamic
Make.When control system breaks down, manual switching-off device breaking circuit breaker can be used.Permanent-magnet manipulating mechanism eliminates traditional mechanism
The mechanical devices such as delicate energy storage, lock simplify structure, and number of parts reduces 70% or more compared with traditional mechanism, to big
Big reliability and the service life for improving mechanism.Using capacitance as operation power, traditional mechanism is avoided to large capacity Special electric
Since source and the influence of accessory power supply fluctuation degree mechanism action characteristic.The MS1 types permanent-magnet manipulating mechanism of performance brilliance can be grown
Phase frequent operation, service life are up to 100,000 times.Permanent-magnet manipulating mechanism uses all-electronic intelligent power control unit, can use extensively
It is controlled in the splitting or integrating lock of various permanent-magnet manipulating mechanisms.Intelligent power control unit is generally at least by main switch power supply, control electricity
Source, capacitor group, push-pull drive switch mosfet device, divide-shut brake position detector, photoelectric isolating device composition.
It is the current situation about breaker and its composition above, although the comparison of operation and control technology development is smart
It is close, however the devices such as vacuum circuit breaker and the switchgear comprising vacuum circuit breaker and component, still remain following deficiency:
(1) its overall structure is mostly positive-installed arrangement, i.e., the arranged direction of three-phase galvanic circle is opened with AC metal closed
The front of equipment is closed into parallel relation.In installation and operation, very large space is not only occupied, also to expend a large amount of copper conductor
It is electrically connected, causes that alternating-current closed switch equipment volume is big, galvanic circle is long, tie point is more, energy consumption is big, is manufactured into
The problems such as this height, poor operational reliability.Therefore the structure and functional regional division of rational composition and switchgear, it appears quite heavy
It wants.Breaker is frequently not individualism, how by breaker and other component reasonable Arrangements, is formed compact, small-sized
The combined electrical apparatus of change is worth thinking.
(2) pole is the critical elements of breaker, and performance directly affects the efficiency of breaker, and current pole performance
It is in urgent need of strengthening.The structure of pole directly affects its performance.
(3) in breaker and its existing switchgear, there are the bullets such as many tripping springs, tension spring, energy-stored spring
Spring class device, and one in these springs once falls off, or relaxation, it will make the functional failure of device in combination,
It will also result in the unstable of breaker or failure, it can be seen that, how effectively to monitor, judges whether spring is in normal work
It is the very important problem in breaker use as state.
(4) group is filled with many components in switchgear, the process of dispatch from the factory in these components installation or repair assembling
In, there is an orientation problem, how to design a kind of simple, efficient positioning auxiliary apparatus so that above-mentioned installation or
Assembling becomes handy.
(5) many switchgears are designed to that for movable type, its underpart include chassis vehicle, how to ensure chassis vehicle in difference
Application ground can held stationary/level.
(6) permanent magnet mechanism controller is the key control unit of permanent magnetic actuator vacuum circuit breaker, commonly uses permanent magnetic actuator vacuum
The intelligence degree of controller is not high, and route protection and monitoring function are insufficient, and switching on and off bridge-type IGBT drive circuit is generally through light
It is electrically isolated and by digital signal processor drive control (IGBT is insulated gate bipolar transistor), and storage capacitor generally passes through
Charging circuit charges, and the design of such mode can be cost-effective, but drive signal exists in terms of anti-interference and reliability
Deficiency, be easy to cause IGBT units cannot reliably turn-on and turn-off, directly affect the performance of divide-shut brake.
