Description
Technical field
The utility model relates to the high-power resistance in novel super (spy) high voltage power transmisson system, more particularly to one kind are novel
High-power high voltage bearing sheet serpentine resistive, belongs to extra-high voltage direct-current transmission and remote conveying power transformation technology field.
Background technique
In the single-stage Transmission Mode of super (spy) high voltage power transmission, in the larger range of earthing pole periphery, the electricity of each substation
Power transformer neutral point flows into DC magnetic bias current.DC magnetic bias current can be such that the iron core of transformer magnetizes, current waveform distortion,
Vibration and noise aggravation.When DC magnetic bias current greatly to a certain extent, will seriously affect transformer safety operation.In existing change
In power station, transformer neutral point is directly grounded by reactor.The safety operation level of transformer is improved, i.e., can be had
Effect inhibits transformer neutral point DC magnetic biasing electric current, and can reliably protect the transformer neutral conductor from due to high current overvoltage
Damage it is apparatus insulated, just must substation's neutral ground circuit of influenced by DC magnetic biasing install additional resistance device.If in original
It installs resistance device behind reactor additional, exists and take up a large area, scene increase equipment is more, and the difficulties such as construction cost height have
Substation can not even install additional in original space.Even if some can install additional, but can carry larger current due to existing
Series resistor piece head and the tail are welded to connect by chip resistor with connection sheet again after usually being concatenated by multi-disc resistor disc by screw rod
And it forms.The chip resistor of the form, though biggish electric current can be born compared with wire wrap resistor.But due between resistor disc
Connection using connection sheet connect, easily formation welding defect, junction contact resistance is larger, easily generate heat when high current passes through,
To limit the current carrying capacity of chip resistor.
Simultaneously in super high voltage direct current electricity transmission or extra-high voltage DC transmission system, the harmonic wave that the change of current generates is to transmission of electricity quality shadow
Sound is larger, influences to eliminate these harmonic waves, generally need to install filter in converter station, filter resistor is the important set of filter
At part.Between the wire wrap resistance of filter resistors, patch unit or pellet resistance unit, generally using between insulated porcelain sleeve
Every, then by metal screw concatenate, to form resistance to combine.However when resistor power is larger, super (spy) high pressure when, due to
Using the size limitation of metal screw concatenation, the creep distance of pellet resistance and screw rod is shorter, and the hidden danger probability of short circuit breakdown is larger.From
And the pressure resistance of resistor and the increase of power are limited under conditions of space is certain.
Therefore, not only volume wants small to the resistance installed additional in super high voltage direct current electricity transmission or extra-high voltage DC transmission system, also
It bears the impact of high current and has biggish power and higher pressure resistance-biggish creep distance, be system for ultra-high voltage transmission resistance
There is technical problem to be solved.
