Detailed Description

The following describes the present invention with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, embodiment 1 of container formula reactive power compensation station include container 1 and the container basis 2 that is used for supporting container 1, the inside room 6 and the secondary room 7 of divideing into of container 1, arranged side by side in the room 6 of once starting cabinet 8 and power cabinet 9, install on the power cabinet 9 and be used for refrigerated fan 10, arranged in the secondary room 7 switch board 11 and lower manhole 12.

As shown in fig. 2, a container vent 4 for drawing air from the container foundation 2 is formed at the bottom of the container 1 on the side of the power cabinet 9 opposite to the fan 10, a ventilation pedal 5 is mounted on the container vent 4, and the ventilation pedal 5 is mainly used for workers to safely pass through the container vent 4 and simultaneously can filter sundries in the air flow to a certain extent. Of course, in other embodiments, the container vents may be located at other suitable locations within the container, as long as wind can enter the container from within the container foundation is not affected; the gas permeable treads on the container vents may be replaced by other structures, such as treads formed on the container floor structure itself, i.e. the container vents are spaced apart at the bottom of the container, and the container floor structure between adjacent container vents may be used for personnel to step through.

As shown in fig. 1, three basic vents 3 for drawing air from the outside are respectively arranged on two longer peripheral walls of a container foundation 2, and a protective net (not shown in the figure) is arranged on the basic vents 3, wherein the protective net mainly has the function of preventing small animals from entering the container foundation 2 to bite cables and is also used for preventing sundries such as leaves from entering the container foundation 2 and further entering the container to influence the normal operation of equipment. Of course, in other embodiments, the number of the basic vents formed in the wall of the container foundation may be other than three, as long as the cooling requirement of the power cabinet is met and the strength of the container foundation is ensured; the basic ventilation opening can also be arranged on a shorter surrounding wall of the container base, and the requirements are met.

As shown in fig. 2, a rain cover 13 is arranged on the container foundation 2 and above the foundation ventilation opening 3, and the rain cover 13 mainly prevents a large amount of rainwater from entering the container foundation 2. Of course, in other embodiments, the above-mentioned rain-proof cover can also be set up corresponding position department on the container, as long as can block to a certain extent that the rainwater gets into in the container basis can.

As shown in fig. 1 and 2, a step 14 is provided at the shorter peripheral wall of the container base 2, and the purpose of the step 14 is to facilitate the entry of workers into the container 1. Of course, in other embodiments, the steps may be replaced by other auxiliary devices such as ladder stands, and the like, which also meets the requirements.

The bottom of the container foundation 2 is provided with a water accumulation pit for accumulating rainwater entering the container foundation 2 and a drainage pipeline for draining rainwater in the water accumulation pit out of the container foundation 2, the terrain of the water accumulation pit is slightly low, so that rainwater can conveniently flow into the water accumulation pit, and the arrangement can prevent the excessive rainwater accumulated in the container foundation 2 from corroding cables or power electronic components in equipment due to the fact that the rainwater volatilizes to cause the excessive humidity of air in the container 1. Of course, in other embodiments, considering that the rain cover blocks most of the rainwater, the water accumulation pit and the drainage pipeline may not be provided, and the use of the container type reactive compensation station is not affected.

Above-mentioned container formula reactive compensation station is when using, fan 10 cools off power cabinet 9 from external convulsions, wind is earlier in getting into container basis 2 through basic vent 3 from the external world, then in getting into container basis 1 through container vent 4 again, and then cool off power cabinet 9, because basic vent 3 tops are equipped with rain-proof cover 13, can prevent to a certain extent that the rainwater from getting into in the container basis 2, and just even the rainwater gets into inside container basis 2 from basic vent 3, the distinguished and admirable need be through a process from bottom to top in getting into container basis 2 from container basis 1, receive the effect of rainwater self gravity, the rainwater can instil into the bottom on container basis 2, so can further avoid the rainwater to get into inside container basis 1.
