Abstract
The utility model discloses an assembled shunt capacitor device. The device comprises two shunt capacitor groups, a series reactor connected with the shunt capacitor groups, a post insulator, and a current transformer; and the three phases A, B and C of each shunt capacitor group are placed in an overlapped manner. By adopting the technical scheme, as the three phases A, B and C of each of the two shunt capacitor groups are placed in an overlapped manner, the whole device only comprises two capacitor towers, so that the occupied area is greatly reduced, specifically a quarter of that in the conventional scheme, which creates favorable conditions for engineering optimizational electrical arrangement; to cooperate the overlapped arrangement of the capacitor devices, the series reactor can also adopts the three-phase overlapping installation method, which also reduces the occupied area to a certain extent; and moreover, a discharge coil is eliminated, which also creates favorable conditions for structural improvement of the capacitor device.
Description
Technical field
The utility model belongs to a kind of power equipment, specifically relates to a kind of assembled parallel capacitor device.
Background technology
The version of low voltage parallel capacitor device is the principal element that influences 500kV transforming plant main transformer and low-pressure side power distribution equipment layout.
At present, the parallel capacitor device that adopts of 500kV substation generally has three kinds of assembled, aggregation type and Tank Capacitors.
Traditional integrated capacitor device is formed by separate unit shell-type capacitor bank, but puts it among the casing, utilizes the usefulness of transformer oil as insulation and heat radiation.Though this product has advantages such as floor space is little, operation maintenance is easy, reactive compensation capacity loses greatly when fault is stopped transport, thereby has limited its use in 500kV transformer station.
Tank Capacitors is a kind of capacitor device of newly releasing on the basis of introducing day present technique Wuxi day, and profile and integrated capacitor are similar, and internal structure is similar to the shell-type cell capaciator, and failure rate is lower, but size is bigger.
Assembled capacitor package unit is combined by connection in series-parallel by many shell-type capacitors that are installed on the framework, and technology maturation is stable, protects perfectly relatively, and the operational percentage height is subjected to the welcome of the department that moves, and is most widely used.
But be aimed at present assembled capacitor device,, cause floor space too big because they all adopt transversal arrangement in transformer station.As shown in Figure 1 and Figure 2, its transverse width approximately needs 13000mm, vertical about 11000mm of span, and not only floor space is excessive, and project cost is too high.
Summary of the invention
The purpose of this utility model provides the little assembled parallel capacitor device of a kind of floor space.
For achieving the above object, the utility model is by the following technical solutions:
The utility model comprises Shunt Capacitor Unit and the series reactor that is connected with Shunt Capacitor Unit, post insulator summation current transformer etc.
With the A in each Shunt Capacitor Unit, B, C three superimposed placements.
With the A in the series reactor, B, C three superimposed placements.
In the assembled parallel capacitor device, high-voltage arrester is set.
Above-mentioned current transformer is located at junction, two shunt capacitor series block middle parts.
Anti-bird cap is set on each cell capaciator of Shunt Capacitor Unit.
Adopt the utility model of technique scheme, owing to placement that A, B in two Shunt Capacitor Unit, C three-phase are superposeed respectively, integral body only is made up of two capacitor towers, so just significantly reduced its floor space, make it narrow down to 25% of conventional scheme, for the engineering optimization electrical arrangement has been created advantage.Place for the stack that cooperates capacitor device, series reactor also can adopt the mode of three-phase closed assembly, and this has also dwindled floor space to a certain extent.In addition, in the utility model, cancelled the setting of discharge coil, also created advantage for the capacitor device structure optimization.For improving capacitor device running environment, reduce maintenance workload, anti-bird cap is set on the extraction tube of each cell capaciator, insulated conductor is adopted in the connection between the cell capaciator.

Embodiment
As shown in Figure 3, Figure 4, the utility model comprises Shunt Capacitor Unit 1 and the series reactor 2 that is connected with Shunt Capacitor Unit 1, post insulator 3 summation current transformers 4.
Arrange size for dwindling capacitor device, with A, B in each Shunt Capacitor Unit 1, C three superimposed placements, package unit only is made up of two capacitor towers like this, and each capacitor tower is respectively A, B, C three-phase capacitor from top to bottom.In addition, in the present embodiment, adopt the cell capaciator of 96 625kvar to constitute 60Mvar Shunt Capacitor Unit 1.
For cooperating the lateral dimension of Shunt Capacitor Unit 1, series reactor 2 also adopts three-phase closed assembly scheme, is about to A, B, C three superimposed placements in the series reactor 2, by selecting suitable terminal to draw angle, guarantees the electrical distance of equipment room line then.Because Shunt Capacitor Unit 1 and series reactor 2 all adopt the mode of three-phase closed assembly, for reducing device height, Shunt Capacitor Unit 1 framework and series reactor 2 all adopt low level to arrange, fence is set all around.For making things convenient for the earthed switch operation, operating mechanism is placed on the fence outside.
In addition, the utility model has been cancelled discharge coil, for the structure optimization of shunt capacitor the complete sets of equipment creates favorable conditions.On the one hand, high-voltage large-capacity capacitor group all adopts the higher current protection of sensitivity to replace voltage protection; On the other hand, discharge resistance is equipped with in cell capaciator inside, can in GB official hour 10min voltage drop be low to moderate 24V.Based on these 2 considerations, the cancellation discharge coil is feasible.
In addition, combined bracket is set, in order to current transformer 4 and neutral ground switch to be installed in Shunt Capacitor Unit 1 neutral point side.And in the assembled parallel capacitor device, high-voltage arrester is set.
For improving capacitor device running environment, reduce maintenance workload, anti-bird cap is set on the extraction tube of each cell capaciator, insulated conductor is adopted in the connection between the cell capaciator.
