Transformer maintenance technology field.
Background technique
Converter power transformer is vital key equipment in super high voltage direct current electricity transmission engineering, is AC and DC transmission system
In rectification, two end interface of inversion core equipment, its investment and safe operation be the key that engineering obtain power benefit with
Important guarantee.As voltage class improves, converter power transformer switching will cause the internal gas that produces and have become universal phenomenon, gas
Accumulation causes the oil in switch grease chamber contaminated, and major accident can even occur to a certain extent for accumulation.Traditional change of current transformation
Not set draw oil sample of device switching system detects interface and equipment, can not estimate circuit-breaker oil chamber interior oily pollution situation, is that the change of current becomes
The major safety risks of depressor safe operation.The converter power transformer to have put into operation such as detects oil sample inside switch grease chamber,
Oil can only be taken in switch oil filter position, a large amount of Residual oils of the switch grease chamber into switch oil filter pipeline need to be emptied, and take out oil
Sample is the mixture for switching trapped fuel in grease chamber and pipeline, not can guarantee detection data accuracy.Meanwhile existing converter power transformer
In, switch oil conservater capacity very little, and switch oil circuit and ontology oil circuit is mutually indepedent, every time from switch oil filter position take it is oily into
After row detection, due to taking oil mass very big, it has to manually march into the arena, carry out repairing to switch oil conservater using oil pump, this process is not
Energy hot line job, just can be carried out after needing converter power transformer to stop transport, and converter power transformer stoppage in transit will cause serious financial consequences.
Summary of the invention
The object of the present invention is to provide a kind of converter power transformer switches to take oil and on-line intelligence automatic oil recharging device and method,
It not only can solve converter power transformer switch grease chamber and directly take oily test problems, while oil conservater and ontology oil circuit connection will be switched,
When tap switch oil conservater oil level is low, repairing can be carried out to switch oil conservater from ontology oil circuit automatically, be not necessarily to converter power transformer
Stoppage in transit can carry out automatically, and structure is simple, automatic repairing, and economy is high.
The technical scheme is that
A kind of converter power transformer switch takes oil and on-line intelligence automatic oil recharging device, becomes ontology, repairing union, switch comprising the change of current
