Technical field
The present invention relates to a kind of evaporative cooling power transformer FC coolant drying device, belong to power system transformer substation equipment operation and maintenance technology field.
Background technology
Evaporation cooling technique is a kind of efficient cooling technology, and its principle is to utilize cooling fluid when vaporization boiling to take away a large amount of heats, and forms the phase transformation self-loopa and efficiently cool off, and is the autonomous innovation technology with China's independent intellectual property right.
Evaporation cooling technique is applied to the evaporative cooling power transformer of urban distribution network; Utilize the non-flammable characteristic of coolant; Can improve the security against fire level of city net, the characteristics according to self-loopa phase transformation cooling can reduce the equipment operation noise; Especially the high load capacity compact district in the big city; Equipment installing space, place such as high stored building group is narrow and small, and fire prevention, requirement of explosion proof are high, and moderate vapour-cooled transformer energy consumption is low, volume is little, safe, environmental protection, the ideal that will become China's electric power system are selected.
At present, to this brand-new evaporative cooling power transformer, also there is not special-purpose repair and maintenance equipment.The cold medium FC of evaporation that power transformer uses need carry out dried, does not also have the drying device of special FC coolant.
Summary of the invention:
The objective of the invention is to there not being the drying device of special FC coolant, proposed a kind ofly by circulation mozzle, by-pass valve control, molecular sieve, forced circulation module with add thermoelectric wire and forms drier, realize FC coolant drying.
Technical scheme of the present invention is: a kind of evaporative cooling power transformer FC coolant drying device; Be composed in series by first by-pass valve control, circulation mozzle, the dry path of two-way parallel connection, forced circulation module, second by-pass valve control; It is characterized in that: the dry path of two-way parallel connection respectively by drying receptacle, molecular sieve, add thermoelectric wire and form; Wherein be provided with molecular sieve in the drying receptacle, drying receptacle is provided with heating electricity silk outward.Its beneficial effect is: a kind of drying device of FC coolant is provided, has realized the cooling to the evaporative cooling power transformer.
Aforesaid a kind of evaporative cooling power transformer FC coolant drying device is characterized in that: said forced circulation module is composing in parallel with first valve after by the second valve series circulation pump.Its beneficial effect is: can provide online and carry out drying operation with two kinds of work patterns of off-line.
Aforesaid a kind of evaporative cooling power transformer FC coolant drying device is characterized in that: the dry path of two-way parallel connection both sides are respectively arranged with valve.Its beneficial effect is: can provide online and carry out drying operation with two kinds of work patterns of off-line.

Embodiment
The explanation of mark among the figure: 10-oil tank of transformer or media Containers; 20-outlet pipe; 30-radiator; 40-liquid back pipe road; 50-the first by-pass valve control; 52-valve; 55-dry pipeline; 60-valve; 70-drying receptacle inlet flange; 80-drying receptacle; 90-electrical heating wire; 95-molecular sieve; 98-filter screen; 100-drying receptacle outlet(discharge) flange; 110-valve; 120-the first valve; 130-circulating pump; 140-the second by-pass valve control; 150-the second valve.
Below in conjunction with accompanying drawing, the embodiment of the invention is elaborated.
Evaporative cooling power transformer FC coolant drying device is on former cooling circuit, to increase a drying cycles bypass.This bypass is parallelly connected with circulation circuit through valve.Its structure is as shown in Figure 1 by circulation mozzle, by-pass valve control, molecular sieve, forced circulation module with add thermoelectric wire.
When valve closing: the drying cycles bypass is not worked.
This FC coolant molecular sieve is made up of dedicated substances.Suitable selector switch valve state, circulating pump can force the FC coolant to circulate through molecular sieve, realizes functions/drying.Add thermoelectric wire and can sieve the moisture that filters out by vapor molecule.
Evaporative cooling power transformer FC coolant drying device characteristic (1) adopts the molecular sieve filtration technology to realize the drying to the FC medium.
Evaporative cooling power transformer FC coolant drying device characteristic (2) has adopted parallelly connected bypass structure.Realize online dried.
Evaporative cooling power transformer FC coolant drying device characteristic (3) has adopted Electric heating evaporation dehumidifying.
Fig. 2 is the structural representation of embodiment of the present invention, the operation principle and the process of evaporative cooling power transformer FC coolant drying device:
The course of work:
Under the transformer normal operation, when not carrying out dried: turn-off 140 second by-pass valve control valves, 50 first by-pass valve control valves.
When if transformer is stopped transport:
Can open 140 second by-pass valve control valves, 50 first by-pass valve control valves, 150 second valves.Turn-off 52 valves, 120 first valves
Circulating pump forces medium to circulate through two molecular sieve drying containers at coolant; Flow back in the oil tank of transformer again.
When the molecular sieve moisture absorption too much, need be to molecular sieve drying, close 60 valves, 110 valves in turn, two drying receptacles select one to quit work.Unlimited suitable for reading, to its electrical heating wire 90 energising heating, dry intramolecular moisture.Be reinstalled drying device again, do not influence operation.
