Capacitor capable of limiting inrush current

Abstract

The invention provides a capacitor capable of limiting inrush current. The capacitor comprises a plurality of current-limiting single bodies, a copper bar, a bridging wire, a first wire and a second wire, the plurality of current-limiting single bodies are longitudinally connected in parallel through the copper bars and then transversely connected in parallel through the bridging wires to form a capacitor core. The first wire and the second wire are used as electrodes at two ends of the capacitor and are respectively connected with the capacitor core; each current limiting single body comprises an inductance coil and a capacitor core body, and the inductance coil is connected with the capacitor core body in series. By adopting the flow limiting single bodies, the occupied types of middle semi-finished products can be reduced, the production efficiency is improved, the standardization degree is greatly improved, the assembly structure is simple and reliable, application and popularization are convenient, an automatic identification basis is further achieved for enterprises in the later period, and meanwhile high-quality products can be provided for the society more efficiently.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a capacitor for limiting inrush current. Background technique [0002] At present, the structure of the anti-inrush low-voltage capacitor is to install a small coil with an appropriate reactance ratio between the core inlet and outlet lines and the capacitor terminal to suppress the inrush current value when the low-voltage capacitor is switched. However, capacitors have many capacitance values. In order to accurately match the reactance ratio, it is necessary to design and process many kinds of inductors with different reactance values. There are many varieties, the module standardization degree is not high, there are many types of semi-finished products, and the processing cycle is long and the assembly efficiency is low. Contents of the invention [0003] In order to solve the above problems, an embodiment of the present invention provides an inrush current limiting capac...
