Abstract

The invention relates to the technical field of single-phase power supply filters, and discloses a single-phase power supply filter with a novel structure. The single-phase power supply filter comprises a single-phase power supply filter, a feed-through filter is fixedly connected in the single-phase power supply filter, and a shell is fixedly mounted on the outer surface of the single-phase power supply filter. The interior of the feed-through filter is electrically connected with a feed-through capacitor, the inner wall of the feed-through filter is fixedly connected with a first silk screen gasket, and the outer surface of the feed-through filter is connected with a second silk screen gasket in a clamped mode. According to the single-phase power supply filter with the novel structure, a single-phase power supply signal is directly accessed from a cable gland I, and the cable gland I is used for rotationally fixing a connecting part, so that the incoming line of the single-phase power supply filter is fixed, and then the single-phase power supply signal subjected to filtering processing is transmitted to a load by a cable; and the signal processed by the single-phase power supply filter is conveniently output, so that a wire inlet cabin and a wire outlet cabin are omitted, and the effect of simplifying the product structure is achieved.

Description

technical field [0001] The invention relates to the technical field of single-phase power supply filters, in particular to a single-phase power supply filter with a new structure. Background technique [0002] The power filter is an electrical device that effectively filters out the frequency of a specific frequency in the power line or frequencies other than the frequency point. The function of the power filter is to obtain a specific frequency by connecting the power filter to the power line. Power signal, or the power signal after eliminating a specific frequency, single-phase power, usually refers to any phase line in the 380V three-phase four-wire AC, when the single-phase power is connected to the load, the load receiving end may receive The fluctuating power signal requires us to use a power filter to limit the power signal, so as to avoid the power signal that is not within the receiving range of the load and damage the load electrical appliances. [0003] A common ...
