Problems solved by technology

However, due to the large number of transformers in the rural power grid, the manufacturing cost of the power distribution room is large and the space occupied is large, so many transformers in the rural power grid cannot be equipped with a power distribution room
The existing active filter device has poor waterproof performance, and the filter compensation of the transformer needs to be realized through the power distribution room with high manufacturing cost, which cannot meet the filter compensation requirements of outdoor transformers
[0003] Therefore, at construction sites in remote areas, due to the rapid changes in the output of large-scale equipment on site and the influence of nonlinear loads, a large number of harmonic components appear in the system, which interferes with the normal operation of nearby users' power consumption and communication equipment. The power station is far away, and the original compensation equipment is incompetent. For example, the investment in re-installing compensation equipment is huge

Abstract

The invention relates to a mobile outdoor high-voltage active filtering apparatus. The mobile outdoor high-voltage active filtering apparatus comprises a body; a main casing installed on the body; a power supply module installed on the body; and a high-voltage active power filter which is installed in the main casing and is connected with the power supply module. Compared to the prior art, the apparatus has the advantages of effectively solving the problem of system harmonic waves of a remote region, being good in safety and wide in application scope, and the like.

Description

technical field [0001] The invention relates to an active filter device, in particular to a mobile outdoor high-voltage active filter device. Background technique [0002] With the vigorous development of my country's rural power grids, a large number of transformers have appeared in rural mountain fields and farmers' residential areas. For the filter compensation problem of the rural power grid transformer, the active filter is obviously a high-efficiency and energy-saving solution. However, the existing active filters are mainly suitable for indoor use due to their poor waterproof performance. Therefore, for transformers, the corresponding power distribution room is usually configured. Through the active filter installed in the power distribution room, the purpose of low-voltage dynamic filter compensation is achieved. However, due to the large number of transformers in the rural power grid, and the high manufacturing cost and large footprint of the power distribution r...
