Explosion-proof capacitor

Abstract

The invention discloses an explosion-proof capacitor, which comprises a capacitor shell, a capacitor core module and an explosion-proof layer. The upper part of the capacitor core module is connected to and installed on the upper plate in the capacitor shell, and the lower part of the capacitor core module is connected and installed on the capacitor The lower pole plate, the upper pole plate and the lower pole plate in the housing are provided with a plurality of heat dissipation through grooves to connect the capacitor shell, the opening of the capacitor shell is installed with a sealing cover, and the capacitor shell and the capacitor core module are also installed. There is an explosion-proof layer, and gaps are reserved between the explosion-proof layer and the capacitor shell, the explosion-proof layer and the sealing cover. The structure of the present invention is optimized, and an explosion-proof layer is added between the capacitor shell and the capacitor core module. Even if the capacitor shell bursts, the explosion-proof layer can protect the capacitor core module, so that the capacitor core module can be reused, reducing Waste of resources, significantly reduce costs, easy to use, high practicability.

Description

technical field [0001] The invention relates to the field of electrical facilities, in particular to an explosion-proof capacitor. Background technique [0002] At present, the existing capacitors are usually referred to simply as capacitance, which is a "charged container" and a device that holds charges. Capacitors are one of the most widely used electronic components in electronic equipment, and are widely used in DC blocking, coupling, bypass, filtering, tuning loops, energy conversion, control, etc. in circuits. Generally, there is a cover plate between the insulating layer of the capacitor and the external environment, which is used to seal the inside of the capacitor, prevent contact with the external environment, and play a sealing role. However, there is usually only one cover plate in the prior art and it is arranged on the upper part of the capacitor body. It is difficult to install the capacitor core module, because the capacitor core modules are arranged in a c...
