Buried transformer substation with escape passage

Abstract

The invention relates to a buried transformer substation with an escape passage, which comprises a transformer substation box body; the top plate of the transformer substation box body is provided with an overhaul cylinder and two air funnels; the upper end of the overhaul cylinder is provided with an exit for overhaul personnel to pass; an overhaul cover is arranged at the exit for the overhaul personnel; the inner wall of the overhaul cylinder is fixedly provided with a ladder; the climb ladder connected with the ladder is arranged in the transformer substation box body below the overhaul cylinder; and the buried transformer substation is characterized in that one side in transformer substation box body, which is close to the climb ladder, is provided with a firewall while the other side is provided with a transformer chamber; the firewall is provided with an emergency exit, a set of high-voltage switched cabinets and a set of low-voltage switched cabinets are arranged between the firewall and the transformer chamber, an exit passageway is formed between the firewall and the wall on one side of the climb ladder in the transformer substation box body, and the climb ladder is positioned in the exit passageway. Compared with the prior art, the buried transformer substation has main characteristics that the structural design is more reasonable, the operation is more safe and reliable; as the firewall is arranged on one side of the transformer substation, a fireproof smog safe channel is formed; and meanwhile, an emergency exit is arranged on the firewall, so that overhaul personnel can quickly escape when an accident occurs.

Description

technical field [0001] The invention relates to a power distribution device, in particular to an underground substation with an escape passage. Background technique [0002] Box-type substation is an outdoor power distribution device with safe operation and reasonable layout of distribution pumps today. It integrates high-voltage cabinets, low-voltage cabinets, and transformers, and can be pre-installed. At the same time, it is more convenient to move and transport. At present, box-type substations It mainly includes three categories. The first category is the above-ground substation located on the ground as a whole; the second category is the semi-buried substation with the above-ground operation part buried underground; the third category is the underground substation with most of the above-ground operation buried underground. Type substation, the first two substations are exposed to the ground due to the exposed part of the box, thus destroying the landscape, and the nois...

[0002] Box-type substation is an outdoor power distribution device with safe operation and reasonable layout of distribution pumps today. It integrates high-voltage cabinets, low-voltage cabinets, and transformers, and can be pre-installed. At the same time, it is more convenient to move and transport. At present, box-type substations It mainly includes three categories. The first category is the above-ground substation located on the ground as a whole; the second category is the semi-buried substation with the above-ground operation part buried underground; the third category is the underground substation with most of the above-ground operation buried underground. Type substation, the first two substations are exposed to the ground due to the exposed part of the box, thus destroying the landscape, and the noise is large and incompatible with the current residential area, garden and bustling street scene; the third type of buried substation is less noisy and has an impact on the landscape It is small, but has the following defects: one of the defects is that the internal space is small, which is not conducive to the operation of maintenance personnel, and the second defect is that there are potential safety hazards, because there are special channels for fire prevention, anti-smoke and toxic gas isolation in the substation box , the maintenance personnel cannot escape in the event of an accident
