A multifunctional explosion-proof capacitor

Abstract

The invention discloses a multifunctional explosion-proof capacitor, which comprises an outer shell, wherein a capacitor core body is installed in the outer shell, the capacitor core body is provided with two wiring ends, two external wiring terminals are arranged on an explosion-proof cover, the two wiring ends are connected with the two external wiring terminals through lead wires, the external wiring terminals are connected with external connection wires, a baffle plate is arranged by the side of each wiring end, a spring is arranged between each baffle plate and the corresponding wiring end, a through hole is formed in the explosion-proof cover, the through hole is covered with an aluminum sheet, and the aluminum sheet is provided with a pressure release pipe. Through the arrangement of the springs, the lead wires and the wiring ends are disconnected through the spring when the current of the capacitor core body is too large and causes the wiring ends to heat and melt; the aluminum sheet is broken through firstly when the pressure inside the capacitor is too large, and the pressure is released from the pressure release pipe; and the interior of the capacitor is filled with No.330 methylsilicone oil protection liquid, thus the risk of explosion when the capacitor leaks electricity is further prevented due to the noninflammability of the No.330 methylsilicone oil protection liquid.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to a multifunctional explosion-proof capacitor. Background technique [0002] Capacitors, commonly referred to as capacitors, are the most widely used electrical components in electronic equipment. They are widely used in DC blocking, coupling, bypass, filtering, tuning circuits, and energy conversion control in circuits. Explosion-proof capacitors can prevent the capacitor itself from leaking or the temperature of the shell will rise to generate sparks, which will cause fire and explosion accidents in the capacitor or even the entire electrical appliance, so explosion-proof capacitors are widely used in explosive environments. [0003] In the prior art, explosion-proof capacitors are simply flame-proofed, and capacitor swelling and electric sparks caused by capacitor leakage may still occur during use, causing fire and explosion.
