Description
Technical field
The utility model belongs to technical field of electric equipment, is specifically loaded voltage-regulating electric transformer.
Background technology
Loaded voltage-regulating electric transformer is a kind of transformer of adjustable output voltage, in power transmission, will generate electricity
Pressure drop, and change with the variation of user side load.The variation of user side load will cause voltage in the fluctuation of system voltage
Larger variation.On the premise of reactive power in-situ balance is realized, when variation in voltage is more than definite value, on-load regulator transformer
It can be acted after certain delay, voltage is adjusted, and keep the stabilization of voltage.
Existing on-load regulator transformer generally comprises babinet, is arranged on the in vivo iron core of case, winding and transformer oil,
Transformer oil be generally used for insulation and to transformer generate heat radiate, and transformer heat up during around
The resistance value of group can increase, and caloric value is caused also persistently to increase, therefore it is to reduce the excellent means of transformer loss to accelerate heat dissipation, and
It is now only very slow by the radiating rate of transformer oil natural heat dissipation.
Transformer oil is easily influenced to cause its aged deterioration be subject to air and impurity simultaneously, causes under its insulation performance
Drop.
Utility model content
The utility model is in view of the shortcomings of the prior art, provide a kind of loaded voltage-regulating electric transformer, this kind of on-load voltage regulation electricity
Power transformer can quickly radiate, and so as to reduce the electric energy loss of transformer, and can remove the impurity of transformer oil, prevent
Only its decreasing insulating.
In order to solve the above-mentioned technical problem, the utility model is addressed by following technical proposals：Loaded voltage-regulating power
Transformer including babinet, is provided with winding and iron core and is filled with transformer oil, top is provided on the babinet in the babinet
Portion and bottom are respectively arranged with oil inlet and oil outlet, and recycle oil pipeline is provided between the oil inlet and the oil outlet,
The pump housing is provided in the babinet, on the recycle oil pipeline there are vertical riser portions, filter is provided in the vertical riser portions
Net, the vertical riser portions lower section are provided with filtrate slot, and the filtrate trench bottom is provided with removable end cap, the circulating pipe
Several radiating fins are additionally provided on road, water tank is provided on the outside of the radiating fin, the water tank accesses tap water pipe line.It adopts
The cycling of transformer oil is realized by the pump housing with the structure, impurities are sunk below strainer when transformer oil passes through strainer
It forms sediment to filtrate slot, impurity can be discharged by the end cap for opening filtrate slot, when transformer oil passes through radiating fin by heat
Amount is transmitted in water tank, since water tank access tap water pipe line causes the flowing that the water in water tank can be different to replace, so that
Radiating efficiency improves.
In above-mentioned technical proposal, it is preferred that temperature sensor is provided in the babinet, the temperature sensor passes through control
Device processed is connected with the pump housing.The temperature of pump housing operating can be set using the structure, the pump housing when temperature is more than setting value
Operating, and the pump housing need not move when temperature is less than setting value, so as to save the energy.
In above-mentioned technical proposal, it is preferred that two of the recycle oil pipeline at least parallel connection, and the every recycle oil
Valve is both provided on pipeline.Caused using the structure when a recycle oil pipeline needs to clear up impurity, another recycle oil
Pipeline still maintains unimpeded, does not influence transformer work when clearing up impurity.
The utility model compared with prior art, has the advantages that：Transformation is realized by the pump housing using the structure
Impurities when transformer oil passes through strainer are precipitated to below strainer in filtrate slot, are filtered by opening by the cycling of device oil
The end cap of hopper can discharge impurity, be conducted heat to when transformer oil passes through radiating fin in water tank, due to water tank
Access tap water pipe line causes the flowing that the water in water tank can be different to replace, so that radiating efficiency improves.
