Embodiment 1

[0036] The present embodiment discloses an insulating protection device, including a protection device body 1. Exemplarily, the protection device body 1 is a tank body or a box body. The protection device body 1 is filled with insulating protective gas, and the insulating protective gas includes Oxygen is 0.9% to 1.1%, and the rest is nitrogen and inevitable impurities.

[0037] Hydrogen, helium, argon, neon, oxygen, nitrogen and air are the more common gases, and the thermal conductivity is 0.163, 0.144, 0.0173, 0.0455, 0.0240, 0.0228, 0.0233, respectively. It can be seen that the thermal conductivity of hydrogen and helium The best, but the two gases have low density per unit volume and can take away less heat, and the overall heat dissipation effect is not good. Hydrogen has the possibility of explosion, which is very dangerous. Although neon has good thermal conductivity, its insulation performance is poor, and the cost of argon is high.

[0038] The heat dissipation perf...

Embodiment 2

[0055] A data center protection method of the present embodiment adopts the protection device of Embodiment 1 to charge underwater, including the following steps:

[0056] The upper filling port 2 is connected to the first pipeline 4, the lower filling port 3 is connected to the second pipeline 5, the first valve 6, the second valve 7, the third valve 8, and the fourth valve 9 are all in the open state, open The circulating fan in the protection device body 1 is protected.

[0057] Nitrogen is charged into the protection device body 1 through the lower filling port 3, and the pressure of the pressure reducing valve 10 is adjusted to 3-10Bar. After the nitrogen enters the second pipeline, the space increases and the air pressure decreases, so that the nitrogen pressure at the air inlet is 1.05~1.2Bar, the original air in the protection device body 1 is discharged through the upper filling port 2; when the oxygen volume concentration in the protection device body 1 reaches 1%, s...

experiment example 1

[0060] The influence of different concentrations of oxygen on the insulation level was investigated, and the insulation level of tip discharge at a distance of 20mm under different gases was tested according to the national standard GB311.2GB311.6 high-voltage test technology.

[0061] Table 1 Insulation properties of insulating protective gas under different oxygen content

[0062]

[0063] The results are shown in the table above and figure 1 As shown, when the oxygen concentration is 0.9-1.1%, the insulation level is good, ranging from 7.6KV to 8.0kV, and when the oxygen volume content is 1%, the best is 8.0kV.

Abstract

The invention provides an insulation protection device, a data center protection method and a data center, belongs to the field of submarine equipment protection, and solves the defect of poor insulation performance when a device in the prior art is used for protecting a submarine data center. The insulation protection device comprises a protection device body, the protection device body is filled with insulation protection gas, and the insulation protection gas comprises, by volume, 0.9%-1.1% of oxygen and the balance nitrogen and inevitable impurities. The insulation protection gas can provide good heat dissipation performance and insulation performance, the reliability of equipment is improved, and the maintenance frequency of submarine equipment is reduced.

Description

technical field [0001] The invention belongs to the field of submarine equipment protection, and in particular relates to an insulation protection device, a data center protection method and a data center. Background technique [0002] The data center includes a variety of equipment such as high and low voltage power distribution equipment and servers. When the data center is used on the seabed, it is necessary to set the high and low voltage power distribution equipment and servers in the protection tank. If air is directly charged into the tank, these devices will easily cause insulation aging of high-voltage live parts due to the high concentration of oxygen in the air, and the metal surface will not make good contact after oxidation, especially low-voltage contactors, relays, circuit breakers, and high-voltage circuit breakers. When opening or closing equipment such as the device, a large number of arcs are generated; and the equipment works under the sealing condition o...
