Abstract
The invention relates to metal bellow expansion oil storage tank, mainly comprising a tank cover and metal bellow expansion compensation bodies which are arranged in the tank cover, the metal bellow expansion oil storage tank has the technical characteristics that: at least two or more than two metal bellow expansion compensation bodies are arranged, upper exhaust pipelines and lower oil pipelines of all metal bellow expansion compensation bodies are connected in parallel or in series to form an unified compensation body, the inner part of the compensation body is communicated with a transformer oil tank by the lower oil pipelines and the outer part of the compensation body is communicated with atmosphere. By adopting more than two multi-core structures, compensation volume is increased, the using requirement of power equipment with high-capacity or heavy oil weight can be met, synchronous operation is stable, safe and reliable, and the system service life is prolonged.
Description
Technical field:
The present invention relates to a kind ofly change the compensation arrangement change volume specifically a kind of being applied in the electric power system and matching used two the above multicore body metal bellow expansion oil storage tanks of transformer, the reactor of larger capacity and electric pressure with temperature of oil in transformer.
Background technology:
At present, according to the needs of power industry, power equipment will be gradually to the trend development of superhigh pressure grade, and this is to having proposed higher new demand for the matching used assembly of power equipment.Oil conservator is a significant components of transformer, reactor, and the safe operation of transformer, reactor is played important protective effect.
The metal bellow expansion oil storage tank that in electric power system, uses, it structurally is a cabinet cover and places monometallic ripple compensation core body in the cabinet cover, the inner charge of oil of single core body, communicate with oil tank of transformer by pipeline, the outside communicates with atmosphere, when transformer oil temperature rise or reduction, single core body vertically expands or is punctured into the oil volume variation and compensates.There is following shortcoming in it using discovery:
1, has only a single ripple core body in the oil conservator, volume is limited, can only use for transformer, the reactor configuration of low-voltage, low capacity, not satisfy big capacity, the heavy bigger transformer of oil, the compensation requirement of reactor, have certain limitation in the use;
2, a single core body is if adopt ripple quantity more for a long time in the oil conservator, and longitudinal dilatation is higher, because of ripple is a flexible body, easily produces unstable phenomenon;
3, single core body of oil conservator will cause overall dimension higher, and inconvenience is installed, and influence the insulation distance of transformer.
Summary of the invention:
Deficiency in view of above-mentioned prior art exists the purpose of this invention is to provide a kind of metal bellow expansion oil storage tank that is made of two above multicore bodies, satisfies the power equipment configuration of larger capacity and electric pressure and uses, to guarantee the security of operation of electric power system.
The object of the present invention is achieved like this, it mainly comprises the cabinet cover and places the interior wavy metal expansion compensation body of this cabinet cover, it is characterized in that: the wavy metal expansion compensation body in the cabinet cover is at least two or more, the last gas exhaust piping of each wavy metal expansion compensation body and following pipeline road are in parallel or are in series and make it be unified into unified compensation body, be connected with oil tank of transformer by following pipeline road in the compensation body, the compensation external body communicates with atmosphere.Wavy metal expansion compensation body is as core body, and the inner chamber of two above multicore bodies all is full of iknsulating liquid, and pipeline and oil tank of transformer UNICOM by the bottom have formed hermetic oil piping system, and the outside of two above multicore bodies communicates with atmosphere.In system when operation,, when the oily temperature rise of transformer or when reducing, two above multicore bodies reach the purpose that the compensator transformer oil volume changes along longitudinal axis vertical direction synchronous or expansion with this.
Advantage of the present invention is owing to adopt the parallel-connection structure of two above multicore bodies, has increased compensation volume, can satisfy the use needs of the heavy bigger power equipment of big capacity and oil, makes its synchronous operation steady, safe and reliable, has prolonged system useful life.
Below in conjunction with accompanying drawing the present invention is explained.
Description of drawings:
Fig. 1 is the parallel core schematic diagram of the present invention;
Fig. 2 is a tandem core schematic diagram of the present invention.
Embodiment:
By accompanying drawing as can be known, the present invention is mainly by cabinet cover 1 with place two wavy metal expansion compensation bodies 2,6 in this cabinet cover (this accompanying drawing is only represented two, and a plurality of wavy metal expansion compensation body structures such as four are identical) to constitute multicore body in parallel (wavy metal expansion compensation body is referred to as core body) metal bellow expansion oil storage tank body.Ripple expansion core body is made of two or more multicore bodies, and the unified back in parallel of in-line 2-1, the 6-1 of each core body is connected with following pipeline road 4, and pipeline road 4 is with it and be unified into unified compensation body (see figure 1) under reaching by last gas exhaust piping 3.The inner chamber of compensation body all is full of iknsulating liquid, and the pipeline by the bottom is communicated with oil tank of transformer, thereby has formed hermetic oil piping system, and the outside that compensates body communicates with atmosphere.An end is equipped with oil level indication 5 on the expansion core body, shows that oil level changes, and is accurately directly perceived.
During the core body filled with oil, with the gas emptying in the core body, make all to be full of iknsulating liquid in the core body by gas exhaust piping 3.Do not have negative pressure to produce, remain the pressure-fired characteristic.When transformer in when operation, oily temperature rise or reduce the expansion core body with synchronous or expansion thereupon, thus realize the purpose of compensator transformer oil volume variation.
Two wavy metal expansion compensation bodies 2,6 in the cabinet cover 1 (this accompanying drawing is only represented two, and a plurality of wavy metal expansion compensation body structures such as four are identical) also can constitute series connection multicore body metal bellow expansion oil storage tank body (see figure 2).Promptly except that the oil inlet pipe 6-1 of first wavy metal expansion compensation body 6 with oil tank of transformer is communicated with, the flowline 6-2 warp of this wavy metal expansion compensation body pipeline road 4 down is connected with the oil inlet pipe 2-1 of next wavy metal expansion compensation body 2, the rest may be inferred, is a compensation body with the series connection of multicore body.
Claims (3)
