Description

A kind of vent passages that partly buries preassembled transformer station

Technical field

The utility model relates to distribution terminal transformer station, particularly a kind of vent passages that partly buries preassembled transformer station.

Background technology

Box-type substation is called for short case and becomes, and is indispensable special equipment in the distribution system.Box-type substation mainly comprises according to its version: ground type, be provided with on the ground, and there is the shortcoming that noise is big, electromagnetic radiation is big, area occupied is big; The full-buried type case becomes, and all is arranged on below ground, and cost height, volume are big, site operation suffering comparatively; Half buried, overcome on the one hand that the noise that the ground type case becomes is big, electromagnetic radiation, problem such as antitheft, becomes than the full-buried type case on the other hand, and production cost greatly reduces, site operation is more convenient.

Have broad prospects though but existing half buried case becomes, structurally still exist some defectives at present: volume is bigger, and floor space is bigger, and the transformer ventilation and heat is in bad order.

The utility model content

The purpose of this utility model has been to provide a kind of vent passages that partly buries preassembled transformer station, has solved the heat dissipation problem of half buried preassembled transformer station, and ventilation condition is good, and greatly reduces the basic expense of transformer.

A kind of vent passages that partly buries preassembled transformer station, transformer station comprises upper box and lower box, upper box is positioned at more than the ground, lower box convex edge part is above the ground level above, other parts of lower box sink to underground, last lower box connects, and it is characterized in that: the top cover of described upper box is provided with ventilation hole; Be provided with hyperbaric chamber, high-tension cable wiring chamber, low-pressure chamber, capacitor chamber and the upper air duct of mutual separation in the described upper box; Separate in the described lower box and be provided with transformer room, high-tension cable inlet wire passage, low-voltage cable inlet wire passage, the lower air duct of placing transformer; The top in described hyperbaric chamber is communicated with ventilation hole, and the bottom in hyperbaric chamber is communicated with lower air duct, and lower air duct is communicated with the bottom, transformer room, and top, transformer room is communicated with upper air duct, and upper air duct is communicated with ventilation hole.

Be provided with ventilation hole around on the described top cover.

Be provided with active clapboard between described transformer room and the lower air duct, the active clapboard bottom is provided with ventilating opening, enters the air inlet of transformer room as cold air.

Described hyperbaric chamber and capacitor chamber are provided with forced draft fan.

The described vent passages that partly buries preassembled transformer station utilizes cold air to sink, and the principle that hot-air rises designs.Cold air becomes the top by case and enters the hyperbaric chamber, sinks to the transformer room through lower air duct again, and cold air rises to case with the transformer heat through capacitor chamber through the transformer room and becomes top discharge case change outside.The pressure reduction that the design of this programme has made full use of cold and hot air forms cross-ventilation, takes away case and becomes interior heat.

The beneficial effects of the utility model are as follows:

Structural design of the present utility model has not only reduced case effectively and has become floor space, alleviates the problem of urban land anxiety, has also solved antitheft problem, has reduced case and has become noise and electromagnetic radiation, makes the environmental protection more of case sell of one's property product; The design of unique vent passages, reduced floor space, under the prerequisite of not selecting special transformer for use, the equipment that guaranteed moves reliably and with long-term, can also greatly reduce case and become basic expense, make site operation very convenient, and can under the situation of not falling appearance, guarantee the heat radiation and the normal operation of transformer.

Embodiment

Shown in Fig. 1-4, a kind of vent passages that partly buries preassembled transformer station, transformer station comprises upper box 1 and lower box 2, upper box 1 is positioned at more than the ground, the convex edge part 3 of lower box 2 is above the ground level above, lower box 2 other parts sink to underground, and upper box 1 is connected with lower box 2, and the top cover 4 of described upper box 1 is provided with ventilation hole; Be provided with hyperbaric chamber 5, high-tension cable wiring chamber 6, low-pressure chamber 7, capacitor chamber 8 and the upper air duct 9 of mutual separation in the described upper box 1; Separate in the described lower box 2 and be provided with transformer room 10, high-tension cable inlet wire passage 11, low-voltage cable inlet wire passage 12, the lower air duct 13 of placing transformer; The top in described hyperbaric chamber 5 is communicated with ventilation hole, and the bottom in hyperbaric chamber 5 is communicated with lower air duct 13, and lower air duct 13 is communicated with 10 bottoms, transformer room, and 10 tops, transformer room are communicated with upper air duct 9, and upper air duct 9 is communicated with ventilation hole.

Be provided with ventilation hole around on the described top cover 4, can be designed as the shape that bar shaped ventilation hole or other shapes are convenient to ventilate.

Be provided with active clapboard 14 between described transformer room 10 and the lower air duct 13, active clapboard 14 bottoms are provided with ventilating opening, enter the air inlet of transformer room 10 as cold air.This active clapboard 14 can be installed for a monoblock, also can install for the polylith splicing.

Described hyperbaric chamber 5 and capacitor chamber 8 are provided with forced draft fan.

The described vent passages that partly buries preassembled transformer station utilizes cold air to sink, and the principle that hot-air rises designs, and its high and low pressure long cable section of ingoing line passage is positioned at a side of lower box, and separates respectively, and lower air duct is positioned at the next door of high-tension cable inlet wire passage.Cold air becomes the top by case and enters the hyperbaric chamber, sinks to the transformer room through lower air duct again, and cold air rises to case with the transformer heat through capacitor chamber through the transformer room and becomes top discharge case change outside.The pressure reduction that the design of this programme has made full use of cold and hot air forms cross-ventilation, takes away case and becomes interior heat.
