Abstract

The invention discloses a compact integration high voltage power capacitor device, mainly consisting of an integration capacitor module and a box transformer substation module, wherein the box transformer substation module is arranged above the integration capacitor module. The internal mounting and assembling work of the power capacitor device is finished before leaving a factory, so that the power capacitor device can be wholly dispatched. The field installation workload is reduced to minimum, and basically, the whole device needs to be in position, a primary cable connector and a secondary cable connector need to be mounted for work. The integration level is high, the device has the obvious characteristics that the mounting is instant and the use is instant, and the mounting cost of the device and the corresponding mounting risk are reduced at the same time. A platform above the integration capacitor module is taken as a mounting platform, the box transformer substation module is arranged above the integration capacitor module, the layout space in the vertical direction is fully utilized, the structure is fully-closed, the occupied area and size can be effectively reduced, the hazard brought by rain and snow weather, birds trouble, foreign matters and the like can be effectively prevented, and the reliability when the device operates is improved.

Description

technical field [0001] The invention relates to a capacitor device for capacitive power compensation of a power transmission and transformation system, in particular to a compact integrated high-voltage power capacitor device. Background technique [0002] In the power system, with the non-renewable land and rising prices, the construction of substations has formed a trend of miniaturization and compactness of the low-voltage side equipment of the main transformer, in order to further optimize the overall electrical layout and reduce the occupied area. Moreover, in accordance with the requirements of the State Grid Corporation of China, under the condition of ensuring the safety of the power grid operation, it is imperative to reduce the area occupied by the equipment to less than 70%, and it is imperative to develop a miniaturized and compact capacitor device. [0003] Power capacitor devices mainly include capacitor banks (including capacitor units, steel brackets, and wir...
