Abstract

The invention discloses a capacitor energy storage system which comprises a housing and a parallel capacitor voltage-equalizing topological circuit arranged in the housing. The parallel capacitor voltage-equalizing topological circuit comprises a plurality of cascade circuits. Each cascade circuit is arranged on a circuit board. The housing is internally provided with a plurality of vertical separator boards for placing the circuit boards in one-to-one correspondence, an upper separator board above the vertical separator boards, and a lower separator board below the vertical separator board. Gaps for air passing are arranged among the vertical separator boards, the upper separator boards and the lower separator boards. The upper separator board is provided with an upper through hole for each circuit board. The lower separator board is provided with a lower through hole for each circuit board. The housing is internally provided with an air chamber for outwards blowing air. The air chamber is connected with a first air blowing pipe for blowing air to the upper part of the upper separator board, and a second air blowing pipe for blowing air to a space between the upper separator board and the lower separator board. The upper separator board is provided with an upper blocking board for blocking the upper through holes.

Description

technical field [0001] The invention relates to the field of power transmission equipment, in particular to a capacitive energy storage system. Background technique [0002] With the development of new energy technologies, the integration of renewable energy into the grid has become a development trend. The power supply formed by using these renewable energy sources will generate randomness and intermittency in the power grid. In order to accommodate these randomness and intermittency, the energy storage system will become an indispensable and important part of the power grid. The commonly used energy storage system is generally combined energy storage of multiple supercapacitors. The voltage equalization of energy storage cells in a large-scale energy storage system composed of multiple supercapacitor cells has become a key technical problem to be solved urgently. [0003] In order to solve the pressure equalization problem of the energy storage unit, someone proposed a m...
