A Metallized Dry Type High Voltage Capacitor

Abstract

The invention discloses a metallized dry-type high-voltage capacitor, which comprises a capacitor body, a container cover is arranged above the capacitor body, a first terminal is arranged inside the container cover, and a fixed nut is sleeved on the peripheral side of the first terminal. , a spring end is arranged on the lower side of the fixed nut, and an electrical connection assembly is arranged on the lower side of the spring end, a groove is opened on the inner wall of the lower end of the container cover, a pressure spring is arranged in the groove, and a pressure spring is arranged in the groove. A limit block is connected to one side of the limit block, a fixed shaft is connected to the bottom end of the limit block, a through hole is arranged in the rear inner wall of the container cover, and a tapered threaded ring is connected to the rear end of the through hole. By designing both the first terminal and the second terminal to be arranged in the container cover, it is avoided that the terminal is covered with a dust layer when it is exposed for a long time. Through the design, a through hole is left to facilitate wiring. The designed slider can control the opening and closing of the through hole through the rotation of the handle, so as to avoid the entry of flying insects and other sundries when no one is using it.

Description

technical field [0001] The invention relates to a high-voltage power capacitor bank, in particular to a metallized dry-type high-voltage capacitor. Background technique [0002] A capacitor is an element that stores electricity and electric energy (potential energy). One conductor is surrounded by another conductor, or the electric field lines emitted by one conductor are all terminated in another conductor. It is called a capacitor. When the two poles of the capacitor When a voltage is applied between the plates, the capacitor stores charge, and the capacitance of the capacitor is numerically equal to the ratio of the amount of charge on a conductive plate to the voltage between the two plates. [0003] The Chinese patent discloses a combined dry-type self-healing high-voltage power capacitor bank. (Authorized announcement number CN98238429.7). In this patented technology, the element body (in a vacuum state) in the capacitor bank is soaked with a layer of oil film. Therefo...

Problems solved by technology

[0004] However, there is no protective cover at the terminal of the top of the dry-type high-voltage capacitor, and the connection is directly in a relatively exposed state. For a long time, the top connection of the dry-type high-voltage capacitor is easy to be attached by dust, and the circuit is prone to not smooth, which is not conducive to Long-term use of dry-type high-voltage capacitors
