The invention relates to a TSR type attenuation-free filter capacitor which comprises a shell, a wire outlet sleeve, a binding post, a filling medium, a discharge resistor, internal fuses and cores, wherein the shell is a cylindrical shell with an opening on one surface, and the opening end is connected with the binding post; the column body part of the binding post is wrapped by the wire outlet sleeve from the interface part of the binding post to the opening end of the shell; each core is connected with one internal fuse, and the m cores and one discharge resistor are connected in parallel to form one core group; and the n core groups are connected in series to form a capacitor array and are connected with the inner surface of the shell through the filling medium. When the capacitor array works, the capacitance of the capacitor array is detected in real time, if the capacitance is m * n-km + 1, k = 1, 2,..., n-1, the working state of each core in the capacitor array is detected, and if the working state of m-1 cores in a certain core group is abnormal, the capacitor stops working. According to the TSR type attenuation-free filter capacitor, the service life of the capacitor is prolonged by detecting the temperature of the cores in the capacitor array.
Description
technical field [0001] The invention relates to the field of capacitors, in particular to a TSR type non-attenuation filter capacitor. Background technique [0002] A capacitor refers to two conductors that are close to each other, with a layer of non-conductive insulating medium in between. A capacitor stores charge when a voltage is applied between its two plates. Capacitors play an important role in tuning, bypassing, coupling, filtering and other circuits. The filter capacitor is an energy storage device, which is often installed at both ends of the rectifier circuit to reduce the ripple coefficient of the AC pulsation and improve the high-efficiency and smooth DC output. [0003] However, the existing capacitors are often unusable as a whole due to the easy damage of the capacitor core and other reasons, and there are problems such as short service life of the capacitor. Contents of the invention [0004] Therefore, the present invention provides a TSR type non-att...
