Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a multi-inner series high withstand voltage film power capacitor to solve the problem that the reactor and the power capacitor with serious heat generation are installed together in the existing process of using the power capacitor. In a confined space, the internal current increases sharply. In a very short period of time, the temperature and pressure inside the capacitor may exceed the critical value, resulting in the possibility of damage or even explosion of the smart power capacitor. The scattered power components, when When there is an explosion, it will affect the surrounding components, causing greater losses and dangerous problems

Abstract

The invention discloses a multi-inner series high-voltage-resistant film power capacitor. The structure includes: a nested board body, a capacitor tube group, a wiring compartment, a radiator, a controller, a converter, and a lock seat, so that when the device is used, it can pass through The nested protection mechanism provided enables the present invention to avoid the sharp increase of the internal current during the use of the power capacitor. In a very short period of time, the temperature and pressure inside the capacitor may exceed the critical value, resulting in the failure of the smart power capacitor. There is a possibility of damage or even explosion. When an explosion occurs, it will affect the surrounding components, so that the equipment can conduct rapid heat transfer through the inner layer plate. On the other hand, when there is a special case of explosion swelling, through the unique The composite layer device and the pressure relief plate device cooperate with each other, so that the shock wave generated by the explosion is fitted by the outer plate device and the inner layer plate, reducing the serial interference caused by accidental explosion between independent components, and effectively protecting the safety of the main circuit.

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...
