Abstract

The invention discloses a multi-internal-string high-voltage-withstanding thin film power capacitor. The capacitor structurally comprises a nesting plate body, a capacitor tube group, a wiring bin, aradiator, a controller, a converter and a lock seat. When equipment is used, a nesting protection mechanism is adopted; when the power capacitor is used in a using process, internal current abruptly increases, the temperature and the pressure in the capacitor may exceed critical values in extremely short time, and as a result, the intelligent power capacitor is prevented from being damaged or evenexploded; when an explosion occurs, surrounding elements are influenced, as a result, rapid heat transfer is carried out on the equipment through an inner-layer plate, and on the other hand, when a special condition of explosion bulging occurs, a special composite layer device and a pressure relief plate device are matched with each other, so that shock waves generated by the explosion are embedded by an outer plate device and the inner-plate device, and therefore, interlink interference generated by accidental explosions among independent parts is reduced, and the safety of a main circuit iseffectively protected.

Description

technical field [0001] The invention relates to a multi-inner series high withstand voltage film power capacitor, which belongs to the field of capacitor equipment. Background technique [0002] Capacitor is a commonly used electronic or electrical device. With the rapid development of electronic information technology, the replacement speed of digital electronic products is getting faster and faster. The production and sales of consumer electronic products mainly include flat-screen TVs, notebook computers, digital cameras and other products. The volume continues to grow, driving the growth of the capacitor industry. [0003] The existing technology has the following disadvantages: in the process of using the power capacitor, since the capacitor installs the reactor with serious heat generation and the power capacitor in the closed space, the internal current increases sharply, and the temperature inside the capacitor and the The pressure may exceed the critical value, lea...
