Abstract
The utility model discloses an oil storage cabinet for an on-load voltage regulating switch of a transformer. The oil storage cabinet comprises an oil storage cabinet body, an oil storage cabinet loading body, an oil storage cabinet cover body, a damp absorber, oil pointers, an oil filling hole and flange plates, wherein the oil pointers are arranged in the middle of the oil storage cabinet body and the oil storage cabinet loading body; the flange plates are arranged at the two ends of the oil storage cabinet body and the oil storage cabinet loading body respectively; the flange plate is arranged at the lower end of the oil storage cabinet cover body and the oil filling hole is formed in the upper part of the oil storage cabinet cover body; and the moisture absorber is connected with the oil storage cabinet cover body through a connecting pipe. One or more sections of oil cabinet bodies are additionally arranged on the original oil storage cabinet to increase the capacity of the oil storage cabinet for the on-load switch of the transformer, so that the oil volume in the on-load voltage regulating switch is regulated and an oil tank of the transformer is ensured to be filled with oil always, and thus the maintenance time is shortened; and the oil storage cabinet for the on-load voltage regulating switch of the transformer is simple in structure, convenient to install, low in cost and easy to maintain.
Description
Technical field
The utility model relates to a kind of protection equipment for transformer, specifically a kind of on-load tap-changer of transformer oil conservator.
Background technology
Electric power system is in operation and often has greatly changed owing to reasons such as operational mode, system wiring, load variations make system voltage, in order to guarantee the desired quality of voltage of each side; Adopt on-load tap-changing transformer to carry out pressure regulation now more and more, to keep the stable of system voltage.On load tap changer is in service at transformer load, in order to the tap of a winding of conversion, change its effective turn, carries out the tap high pressure, and this transformer is called on-load tap-changing transformer.Because on-load tap-changing transformer has above-mentioned advantage, along with rapid development of national economy, the continuous expansion of scale of power, the use of on-load tap-changing transformer more and more widely, the operation of its reliable and stable is particularly important.
Though on-load tap-changing transformer uses in a large number, it is in service along with winter, summer environment difference variation that the part transformer has on-load shunting switch, and oil spilling, petrol starvation have appearred in reasons such as insulating oil expansion, contraction.Past; We have a power failure to on-load tap changers of transformers oil spilling, petrol starvation usually and discharge insulating oil, supplementary insulation oil solve problem; But because it is big to receive ectocines such as work on the spot environment, weather conditions, it is long that personnel need remove the conservator top cover repair time; Need to store a large amount of insulating oils, the cost of overhaul is high; Client's interruption duration is long, and economic interests incur loss, and the quality of good service descends; Simultaneously also bring heavy maintenance task to power supply department.Find by inquiry, though the volume that oil conservator can satisfy transformer oil is regulated the effect of oil mass along with the temperature expansion of oil or when reducing.But because existing oil conservator volume is little, can not satisfy the effect of regulating oil mass because of variations in temperature, thus cause that discharging appears in transformer, makeup oil often, the time is long.Existing transformer not only the interruption maintenance time long and also in maintenance process, take a lot of work, time-consuming, expense material, the repair time is long, the expense cost height, user's power supply reliability does not reach requirement.
The utility model content
To above-mentioned deficiency; The utility model provides a kind of on-load tap-changer of transformer oil conservator; Its volume that not only can satisfy transformer oil is regulated the effect of oil mass along with the temperature expansion of oil or when reducing, and the long problem of interruption duration of release, supplementary insulation oil improves.
The technical scheme that its technical problem of the utility model solution is taked is: the on-load tap-changer of transformer oil conservator, comprise oil conservator body, oil conservator lid, dehydrating breather and oil ga(u)ge, and it is characterized in that, comprise that also oil conservator adds carrier; The middle part that said oil conservator body and oil conservator add carrier is provided with oil ga(u)ge, and two ends are respectively arranged with ring flange; Said oil conservator lid lower end is provided with ring flange, and top is provided with oil filler point; Said dehydrating breather is connected with the oil conservator lid through tube connector.
It is vertical type cylinder body shape that described oil conservator body and oil conservator add carrier.
The beneficial effect of the utility model is: this on-load tap-changer of transformer oil conservator installs one section or many sections Oil Tank bodies additional on original oil conservator basis; Transformer loaded switch oil conservator volume is strengthened; Regulate the interior oil mass of on-load voltage regulating switch and guarantee frequent oil-overflow effect in the oil tank of transformer thereby reach to play, shortened the repair time; Oil ga(u)ge is used for showing the oil mass of insulating oil in the oil conservator; Dehydrating breather adsorbs the wet gas in the on load tap changer, has guaranteed the insulation level of insulating oil, has prolonged the useful life of transformer.The utility model is not only simple in structure, easy for installation, and cost low, be easy to safeguard.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Wherein, 1 oil conservator body, 2 oil conservators add carrier, 3 oil conservator lids, 4 dehydrating breathers, 5 oil ga(u)ges, 6 oil filler points, 7 ring flanges.
Embodiment
As shown in Figure 1; This on-load tap-changer of transformer oil conservator, comprise oil conservator body 1, oil conservator add carrier 2, oil conservator lid 3, in order to the dehydrating breather 4 of moisture in the absorption oil conservator, in order to the oil ga(u)ge 5 that shows the insulating oil oil mass, in order to inject the oil filler point 6 and the ring flange 7 of insulating oil to oil conservator.Described oil conservator body 1 adds carrier 2 with oil conservator and is vertical type cylinder body shape.Said oil conservator body 1 is provided with oil ga(u)ge 5 with the middle part that oil conservator adds carrier 2, and its two ends all are respectively arranged with the ring flange 7 that is used to be tightly connected; Said oil conservator lid 3 lower ends are provided with the ring flange 7 that is used to be tightly connected, and top is provided with oil filler point 6; Said dehydrating breather 4 is connected with oil conservator lid 3 through tube connector.
When this on-load tap-changer of transformer oil conservator is installed; Oil conservator body bottom is connected and sealed through ring flange and on-load voltage regulating switch main body; The upper end adds the carrier bottom through ring flange and oil conservator and is connected and sealed, and oil conservator adds the carrier upper end and is connected and sealed through ring flange and oil conservator lid.Model and environment for use according to transformer; Can a plurality of oil conservators be installed between oil conservator body and oil conservator lid and add carrier; Effective like this volume that increases original oil conservator; Play and regulate the interior oil mass of on-load voltage regulating switch and guarantee frequent oil-overflow effect in the oil tank of transformer, shortened the repair time.Oil conservator body and oil conservator add the oil mass that oil ga(u)ge on the carrier is used for showing insulating oil.Dehydrating breather adsorbs the wet gas in the on load tap changer, has guaranteed the insulation level of insulating oil, has prolonged the useful life of transformer.
