Description

Integrated switch cabinet

Technical Field

The application relates to the technical field of electrical equipment, in particular to an integrated switch cabinet.

Background

SF6 gas has good electronegativity, and its molecules can rapidly capture free electrons to form anions. The electric conduction of the anions is very slow, so that the recovery rate of the intensity of the arc gap medium is accelerated, and the arc extinguishing performance is good. Under the pressure of 1.01X105 Pa, the arc extinction performance of SF6 gas is 100 times of that of air, and the gas does not deteriorate after arc extinction and can be reused.

In a high-voltage use scene, SF6 gas is used as an arc extinguishing medium and an insulating medium, and the performance is excellent. It should be noted, however, that the performance of SF6 gas is also affected by pressure and temperature. For example, the heat generated during the operation of the electrical equipment can raise the ambient temperature, and the pressure of the enclosed space is increased; when a leakage condition occurs, the pressure of the closed space is reduced, and the insulation performance of SF6 gas is affected by unstable pressure.

Referring to fig. 3 and 4, when the pressure in the installation area 11 increases, the elastic membrane 5 is driven by the air pressure to occupy the space in the adjustment area 12, so that the volume of the installation area 11 increases; when the pressure in the installation area 11 decreases, the elastic membrane 5 is driven by the air pressure to occupy the space in the installation area 11, so that the volume of the installation area 11 is reduced.

The air pressure of SF6 gas in the installation area 11 can be fluctuated within a range meeting the requirements by adaptively adjusting the space size in the installation area 11, and the adjustment mode does not need to supplement the SF6 gas, so that the method has higher economical efficiency.
