Description
Technical field
The utility model belongs to power capacitor manufacturing field, and in particular to a kind of high pressure self healing capacitor of being exclusively used in
Fault-signal booster.
Background technology
Oil-free in dry-type high-voltage self-healing type parallel condenser case shell, by its self-healing feature, can prevent medium weakness and
Harm that shelf depreciation is brought and reliably run, be adapted for mount to Urban Underground transformer station, the indoor substation of heavy construction
And emphasis fire prevention place.
This kind of capacitor has self-healing work(for the breakdown as caused by medium electricity weakness and shelf depreciation in very low range
Can, therefore have certain failure protection capability, and capacitor can be made to be run under higher field intensity.When this kind of capacitor is too high
Thermal stress and electric stress in the presence of, medium accelerated ageing trigger large area breakdown and can not self-healing when, puncture position medium
Decomposed by electric arc and produce a large amount of gases, increased dramatically capacitor internal pressure, often result in shell bulge, or even cause quick-fried
Split, other equipment may be damaged.During due to metallization self-healing capacitor component interior media large area breakdown, electrode
Between mainly connected by electric arc, short circuit is unstable, and arc resistance is bigger, the capacitance variations of reflection also unobvious, thus while
Capacitor faults are very serious, there is the danger of explosion, but the capacitance variations illusion such as less easily makes fault-signal by " annihilation ", this
Situation is different from the metallic short circuit of foil type capacitor, and the relay protection to capacitor device standby causes difficulty.Therefore, dry type
The relay protection of high pressure self-healing type parallel condenser internal fault is a still unsolved problem, and sensitive reliable relay is protected
The safe operation protected for capacitor is most important.
At present, the low pressure self healing capacitor used in 1kV or following voltage class power systems is often using pressure protection
Method, this guard method mainly break internal current connection sheet by capacitor case deformation, so as to cut off the electricity supply, make capacitor
It is out of service.But high-voltage parallel capacitor is applied to 6kV, 10kV, 35kV voltage class, if internal use breaks electric current company
The mode of contact pin, the insulation distance and its appearance of fracture of fracture can not meet the requirement of isolated high voltage, between fracture can resume combustion or
Repeated breakdown, the electrical equipment that caused high power overvoltage can be in harm system.Therefore, this tension fracture type protection device high pressure from
More do not applied in formula shunt capacitor.
In summary, the particularity of dry-type high-voltage self-healing type parallel condenser material, structure and operation principle is limited by, its
In addition to the self-healing performance that itself has, its relay protection is the key technology that safe operation needs to solve for the protection of internal fault
Problem.
The content of the invention
In the requirement for power system shunt capacitor internal fault relay protection, the utility model proposes a kind of special
In high pressure self healing capacitor（Hereinafter referred to as " capacitor "）Fault-signal booster.

Line nut connects extraction wire.Traveling electrode component connects extraction wire by wiring nut.Fixed bottom plate and the fixed electricity of installation
Pole component, the insulation tube of traveling electrode component are combined integral by resin-cast.
Fixed bottom plate makes of stainless steel plate, and two ends bending slightly is in favor of be bonded simultaneously spot welding with capacitor inwall.Absolutely
Edge pipe is managed using high density PP, and inner homogeneous is smooth, hole among pipe.Latch uses high density PP rods, smooth in appearance, and one
Slightly taper is held, the other end has fixing hole.Spring material therefor is advanced spring steel, and surface to avoid corrosion, and is prevented through processing
Only prolonged higher temperature environment influences its elasticity.Castable uses epoxy resin.Extraction wire is by fault-signal booster
To capacitor terminal, using insulative multi-strand tin annealed copper wire.
Fault-signal booster is fixed on the big face of capacitor inwall side by fixing bottom plate.By latch it is tapered one
End is inserted perpendicularly into the middle hole of insulation tube, and one end of latch is fixed on the big face of opposite side corresponding to capacitor inwall.Normally
In the case of, the one end for being inserted insulation tube hole by latch by the travelling electrode that spring is withstood is blocked in the center of insulation tube, bullet
Spring is in compression shape.
Under capacitor normal operation, by the travelling electrode that spring is withstood in insulation tube center by one end of latch
Stop, keep enough insulation distances with corresponding fixed electrode body, spring is compressed, and fault-signal booster is in open circuit shape
State.Work as capacitor failure so that when shell expands more than certain size, latch is with the deformation of capacitor case from insulation
It is drawn out in pipe, spring is released, and rapid to drive traveling electrode to be close to fixed electrode, fault-signal booster is in short-circuit condition.
Because travelling electrode is connected respectively on two outlet terminals of capacitor with fixed electrode body, thus makes electricity
Short circuit is formed between container terminal.The reliable short circuit of this metallicity can make capacitor bank produce sufficiently large unbalance voltage or electricity
Stream, enables the relay protection of standby smoothly to detect, and drives breaker actuation, so as to cut off faulty capacitor device, prevents
Capacitor explosion causes the accident.
The beneficial effects of the utility model are：According to the material of dry-type high-voltage self-healing type parallel condenser, structure and characteristic,
Using this fault-signal booster, can solve the Protection Technology problem of self healing capacitor internal fault, effectively keep away
Exempt from the generation of accident.
The utility model is simple in construction, installs, be easy to use, can meet the requirement of capacitor safe operation.
