Description
Technical Field
The utility model relates to the technical field of wind power, in particular to an abrasion-proof coaxial protection device for a cable of a wind turbine generator.
Background
With the continuous increase of the single-machine power of the wind generating set, the number of cables laid on the tower of the wind generating set correspondingly increases. For example, the full power of a double-fed wind generating set with 1.5MW is 1500KW, the voltage is 690V, the current required to be transmitted by the cable is up to 1250A, and the number of the cables is 20 and 185. When the height of the tower is 65 meters, the highest end of the tower can cause the flexible cable to shake due to inertia when the wind is strong or the yaw occurs, and the swinging inertia of the cable which is heavy by nearly one ton is huge. The huge inertia will cause the damage of the insulation layer caused by the continuous friction, impact and the like between the insulation layer and the cable, the tower platform plate and the guide ring, and simultaneously cause the twisting and pulling of the cable. Over time, the cable skin at the junction of the cable, the watch platform and the bracket is damaged by impact and friction, the insulation effect is lost, and an extremely serious short circuit occurs. The fan is inevitably damaged by the dangerous condition of short-circuit discharge, and equipment is damaged. If the discharge is serious, the electric arc can cause the fan fire, and the consequence is not imaginable.
Because the environment of the wind generating set is severe, the service life of the fan is long, and the cable continuously rotates along with the fan, the requirement on the performance of the cable is high. China has wide breadth of members and large difference of the south and north climates. Such as: the northern area requires the low temperature characteristic capable of resisting the temperature requirement of minus 30 ℃ and below; coastal areas require coastal high-temperature characteristics and the like with three-prevention measures of salt fog prevention, damp-heat prevention and mould prevention.
The national standard of cables special for wind generating sets (GB/T29631-2013 rated voltage 1.8/3KV and below for wind power generation) is released in 2013, so that partial complete machine manufacturers can purchase cables which do not meet requirements in 2013 to reduce cost. If a non-flame-retardant material cable is adopted, the cable is ignited and led into the engine room due to the damage of the cable insulating layer, even if the flame-retardant cable meeting the standard is used, the cable is prone to be polluted due to the fact that grease of the gear box, the hydraulic station and other lubricating parts in the engine room leaks outwards, the cable is also enough to ignite to the engine room, a fan is burnt, and great potential safety hazards exist.
