Description
Technical field
The invention belongs to electric energy device field, and in particular to a kind of gas-insulated ring network cabinet metal enclosed switchgear.
Background technology
In order to improve power supply reliability, user is obtained power supply from both direction, power supply network is generally connected into cyclization
Shape.This power supply mode is referred to as ring network power supply, and the power supply station, which matches somebody with somebody, is referred to as ring main unit in switchgear general custom.Ring main unit is
One group of high-tension switch gear is mounted in steel sheet metal cabinet or made the electrical equipment of assembled compartment ring network power supplying units, its
Core uses on-load switch and fuse, has simple in construction, small volume, price is low, can improve power supply parameter and performance
And the advantages that power supply safety.
Ring network power distribution unit is typically made up of 3 intervals, including two inlet-outlet line intervals and a transformer bay every.Disengaging
Line interval is mainly used in the timely isolation to faulty line, and recovers normal power supply by adjusting power supply direction；Transformer
Interval is then quickly cut off by combined electrical apparatus to inside transformer short trouble.
The chief component of ring main unit is on-load switch, is typically named with the type of on-load switch.Divided with this, its
Develop 4 stages mainly undergone, be summarised as air-generating, air pressing type, vacuum ring main unit and SF6 ring main units.
Late 1980s, the beginning of the nineties, air-generating ring main unit are widely used in the whole nation, but its own
Feature determines it when cut-offfing load, and arc light is exposed, easily triggers security incident；Electric life is not high, Maintenance and Repair workload
The shortcomings of big so that air-generating ring main unit has exited the arena of history soon.
Similarly, for air pressing type ring main unit there is also arc light when cut-offfing load is exposed, operating mechanism limitation is larger, and machinery
Life-span is not high, the shortcomings of poor reliability.Thus also fail to obtain extensive promotion and application.
Vacuum ring main unit uses vacuum load switch, its arc-chutes good insulation preformance, and clearance between open contacts are small, it is desirable to operating mechanism
The energy of offer is also small；Meanwhile open away from small, arc voltage is low, and arc energy is small, and contact surface scaling loss is slight when cut-offfing, meanwhile,
Arc-chutes working condition is unrelated with the external world, will not produce pollution, its electrically and mechanically long lifespan.But the mechanical machine of vacuum ring main unit
Structure adapted is complicated, and strict to material requirements, production difficulty is larger, and production prices are higher, simultaneously because vacuum interrupter has very
The strong ability for cut-offfing high frequency electric, in cut-offfing for current over-zero moment, can produce Multiple subcutaneous insulin infusion.Therefore, vacuum is opened
Close often as the equipment that circuit is cut-off in ring main unit, it is mainly used in the control and protection for motor.
As the SF6 of arc-extinguishing medium of new generation, its is colourless, tasteless, nontoxic, will not burn, stable chemical performance, blow-out energy
Power is strong, the features such as good insulation preformance, it is widely used in the breaker of each voltage class.
As one kind in C-GIS Medium Voltage Switchgears, the totally-enclosed property of SF6 ring main units, miniaturization, non-maintaining, high insulation
Type, the major accident that switch cubicle may occur in operation is effectively limit, turn into the master of ring main unit in one period from now on
Flow development trend.
