Positive-pressure ventilation system used for seaborne booster station

Abstract

The invention relates to a positive-pressure ventilation system used for a seaborne booster station. The invention aims to provide the positive-pressure ventilation system used for the seaborne booster station; electric equipment is prevented from being exposed in a corrosive environment on the basis of guaranteeing effective ventilation and heat radiation, the electric equipment does not lose efficiency due to corrosion, and the seaborne booster station can be operated normally for a long time. According to the technical scheme, the positive-pressure ventilation system is composed of a salt mist removing system, a ventilation pipeline system, room pressure leaking devices, room air conditioning systems and monitoring systems, wherein the salt mist removing system is communicated with each equipment room by the ventilation pipeline system; each equipment room is internally provided with one room pressure leaking device, one room air conditioning system and one monitoring system; the salt mist removing system is used for introducing filtered air into each closed equipment room of the seaborne booster station by the ventilation pipeline system so that air pressure in each equipment room is improved; each room pressure leaking device is used for discharging air in the corresponding equipment room so that the positive pressure being 30Pa-50Pa is maintained in the room relative to the outdoor. The positive-pressure ventilation system used for the seaborne booster station is applied to the field of seaborne wind power generation.

Description

technical field [0001] The invention relates to a positive pressure ventilation system for an offshore booster station. It is applicable to the field of offshore wind power generation. Background technique [0002] In my country, offshore wind power generation is an emerging industry. After 2007, my country began to gradually develop the offshore wind power industry. In order to send the electric energy generated by offshore wind turbines to the land, an offshore booster station must be built. At present, there is no offshore booster station built or under construction in my country. [0003] The offshore booster station is the booster, power distribution and control center of the offshore wind farm. The offshore booster station is generally equipped with various electrical equipment such as main transformers, high and low voltage power distribution cabinets, GIS, and communication relay protection equipment. In a closed room, the equipment will generate a lot of heat duri...

AI Technical Summary

Problems solved by technology

[0004] Offshore booster stations are generally located on the coast or near the sea, and the surrounding air has the characteristics of high humidity and high salt fog. Easily corroded and unable to operate in corrosive environments

Conventional ventilation systems are composed of ventilators, ventilation ducts, etc., which directly inhale outdoor air into the room and then discharge it. Such air circulation can effectively take away the heat generated during equipment operation. The air with high humidity and high salt mist in the environment is directly introduced into the room, which is easy to cause corrosion of the equipment, so that the operating life of the equipment is only a few years or even a few months
