In an offshore wind farm, an offshore booster station is used for collecting electric energy generated by an offshore wind turbine and boosting the electric energy. The offshore booster station is provided with a storage battery chamber and a diesel engine chamber, and various electrical equipment for ensuring the normal operation of the offshore booster station are arranged in the storage battery chamber and the diesel engine chamber. In the operation process of the offshore booster station, flammable and explosive dangerous gases such as hydrogen and the like can be generated in the storage battery chamber and the diesel generating chamber (namely, the storage battery chamber and the diesel generating chamber are explosion-proof areas), in order to reduce the explosion risk, a method is generally adopted to make the electrical equipment arranged in the storage battery chamber and the diesel generating chamber be explosion-proof, namely, certain technical measures are taken on the structure and performance of the electrical equipment to reduce the risk of ignition and explosion of the surrounding explosive gas environment, and the explosion-proof electrical equipment has the following defects from the application status:
1. The weight is large: the explosion-proof electric apparatus has a thick and heavy metal casing, a sealing assembly, etc., and the overall weight is heavy as compared with conventional apparatuses, which is disadvantageous to the lifting, transportation, and installation of the offshore booster station.
2. The volume is large: the offshore booster station has a compact structure and precious space resources, and the explosion-proof electrical equipment is larger than electrical equipment with the same power in volume due to the adoption of an explosion-proof manufacturing process.
3. Poor economy, high cost: the cost of explosion-proof electrical equipment is higher than that of conventional electrical equipment, resulting in an increase in the overall cost of the offshore booster station.
4. Potential safety hazards exist: an irregular, incorrect installation would defeat the explosion-proof performance of the explosion-proof electrical equipment. In the installation and construction work, the following problems are common: firstly, no sealing ring is used for cable threading; the sizes of the explosion-proof sealing ring and the cable are not consistent; thirdly, one explosion-proof sealing ring penetrates through a plurality of cables, so that sealing is difficult to realize; fourthly, the redundant cable lead-in port is not provided with a blind pad, and is only plugged by explosion-proof mud (namely cable daub) in field operation. In addition, the untimely degradation and scrapping treatment of the explosion-proof electric circuit also endangers the safe production, and discharge sparks or electric arcs caused by electric leakage or short circuit occur in the electric circuit due to insulation damage. The existence of the problems can affect the safety of the operation of the explosion-proof electrical equipment.
5. Daily overhaul and maintenance and professional overhaul and maintenance are required: the explosion-proof safety performance of the explosive gas environment is guaranteed by relying on explosion-proof electrical equipment with good safety performance and electrical installation with fine workmanship, and also by safe and reliable operation and careful maintenance, which is a system safety project. The maintenance is routine activities for maintaining the explosion-proof electrical equipment in service in a safe state, and the design of the offshore booster station is unattended, so that great difficulty is brought to the maintenance of the later explosion-proof electrical equipment under the conditions of inconvenient and complicated offshore traffic.
