Description

A kind of pulse power high-voltage capacitor

Technical field

The utility model belongs to capacitor technology field, more particularly to a kind of pulse power high-voltage capacitor.

Background technology

High-voltage capacitor is obtained as Active PFC and the main prototype part of reactive power compensation in power system Increasingly it is widely applied, while also the electric property to capacitor proposes higher requirement.Capacitor is by electrode, outer Shell, capacitor body are constituted；Capacitor body can be the cylindrical structural of layer material winding.However, in practice, existing electric capacity Device is not suitable for using in the high-tension circuit of the pulse power.

Utility model content

The utility model provides a kind of pulse power high-voltage capacitor.

A kind of pulse power high-voltage capacitor, including shell, 2 are used for the screw rod and mounting ear of extraction electrode, 2 spiral shells Bar is located at capacitor top two ends,

Inside the capacitor case of square, connecting copper bar and screw rod are welded, at the same connecting copper bar also with capacitor core Sub-component is welded,

Capacitor uses dry construction,

Capacitor body uses flat form, and using being connected in series between capacitor body.

Reinforced between mounting ear and shell using triangle reinforcement.

High-voltage capacitor of the present utility model is used for the filtering of the pulse power, coupling, in the high-tension circuit such as pressure, blocking. Using dry construction, no Leakage, long lifespan, stress levels are high, and loss is small, and conveyance capacity is big, flame retardant rating UL94-V0, Insulation voltage grade is high.
