Description
Technical Field
The invention relates to a high-voltage power distribution cabinet in a power system, in particular to a cooling and dehumidifying device and method for an inner chamber of the high-voltage power distribution cabinet.
Background
The valve arrester in the prior art mainly comprises a wire clamp, a porcelain bushing, a spring, a spark gap sheet, a mica gasket, a porcelain tube, a valve and a valve plate. The working process is as follows: when the arrester is in normal operation state in the system, the valve and the live high-voltage wire of the arrester are isolated by the gap formed by the mica gasket and the spark gap sheet. When an overvoltage occurs and reaches a voltage value thereof, the discharge gap is immediately discharged. Meanwhile, the power frequency follow current flows into the ground. When the overvoltage disappears, the discharge gap ensures that the arc is extinguished, cut off and sink when the first half of the discharge gap is zero, so that the system returns to the normal working state. Although the lightning arrester can play a role in avoiding, the mica sheet gasket of the spark gap inside the lightning arrester is only in clearance fit with the porcelain tube, so that the lightning arrester is easy to loosen under the impact of lightning current, and the lightning arrester can lose the lightning protection effect after long-term use.
