PARTICULATE FILTER AND CYLINDER BODY STRUCTURE FOR GIS/GIL

摘要

A particulate filter and a cylinder body structure for GIS/GIL. The particulate filter (104, 204) comprises: a trap cover plate (1, 21, 31, 41), a cover plate connecting structure being provided on the trap cover plate (1, 21, 31, 41), the trap cover plate (1, 21, 31, 41) being adapted to be detachably and fixedly connected to an opening of a cylinder wall of a cylinder body (101, 201) by means of the cover plate connecting structure; and a trap grid plate (2, 22, 32, 42), which is detachably connected to the trap cover plate (1, 21, 31, 41) so that an equipotential area (10) is formed between the trap grid plate (2, 22, 32, 42) and the trap cover plate (1, 21, 31, 41), grid holes (9) are distributed on the trap grid plate (2, 22, 32, 42), and the grid holes (9) allow metal particulates to pass through so that the metal particulates can enter the equipotential area (10). After the trap cover plate (1, 21, 31, 41) is fixedly connected to the corresponding cylinder body (101, 201), under the action of an alternating-current high voltage, the metal particulates in the cylinder body (101, 201) can move under the action of an electric field and finally pass through the grid holes (9) to enter the equipotential area (10), so that the metal particulates are not affected by the electric field, the metal particulates stop moving, and the metal particulates are captured. Moreover, the trap cover plate (1, 21, 31, 41) and the trap grid plate (2, 22, 32, 42) are both of plate-shaped structures, so that the structure of the particulate filter (104, 204) is simplified.
