By adopting the water sealing well accident oil discharging system, the problem that multiple wells including the water sealing wells and inspection wells cannot be placed because the existing water sealing wells cannot be connected with each other due to small installation space which cannot store a third inlet-outlet can be solved, the quantity of the inspection wells can be reduced, and the occupied area can be reduced.
Description
Technical field
The utility model relates to the trapped well accident oil draining system in a kind of transformer station, belong to the accident oil draining system in transformer station.
Background technology
Substation accident oil draining system generally first enters emergency oil pond with pipeline and manhole again after trapped well.According to existing atlas, the inlet and outlet piping of trapped well is all discharged after water seal below liquid level, the vertical tube relating to is larger, be generally the pipe of DN300, DN400, its top is also equipped with oak plug and is close to well lid, space can only meet the form of one-in-and-one-out in well, makes cannot accomplish to interconnect between trapped well, could be communicated with accident oil draining system after need to first accessing manhole.
Be a kind of conventional trapped well accident oil draining system as shown in Figure 1, 2, 3, it includes trapped well 2, and its import and export being provided with has the accident oil exit pipe 5 of water seal measure, after being communicated with, connects each manhole 4 to emergency oil pond by accident oil exit pipe 6 with manhole 4.
Utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of on the basis of accident oil draining system of optimizing main transformer of transformer substation, the trapped well accident oil draining system in a kind of transformer station of minimizing transformer station floor space.
The technical solution adopted in the utility model is: the combined type water seal Fang Jing in described transformer station, it only has the trapped well of the accident oil exit pipe of water seal measure import being provided with that is communicated with main transformer side, connected and be connected in emergency oil pond between described trapped well by oil exit pipe.
Described trapped well is the Fang Jing that is provided with cat ladder in, and the bottom of trapped well is provided with absolute altitude lower than liquid level absolute altitude 1m base plate in trapped well, and is provided with 100mm top board above ground level at the top of trapped well, and this top board is provided with cover plate for manhole.
The sidewall of described base plate, top board and trapped well is two way system respectively.
Described accident oil exit pipe, by the fixing trapped well of support, is submerged in the following 400mm of liquid level in trapped well at the bottom of the pipe of this accident oil exit pipe.
The utility model is by the optimal design to existing prior art, the inlet pipe that square manhole is connected to main transformer oil hole has done water seal measure, inlet/outlet pipe between well and well does not do water seal, has formed a novel water seal Fang Jing that can be interconnected, and has reduced the quantity of manhole; In addition, adopt square manhole, rationally utilized the excavation area while construction, reduced transformer station's occupation of land.
The utlity model has following useful technique effect:
Adopt after trapped well accident oil draining system described in the utility model, solved the problem that traditional trapped well cannot intercommunication, station interior conduit attractive in appearance is arranged effect, has reached and has reduced the object that transformer station takes up an area; The water seal way of the trapped well outlet that connects main transformer oil hole is cancelled, take direct current, having solved is unable to hold because installing space is little between existing each trapped well the 3rd, and import and export cannot be interconnected, the problem that causes trapped well and manhole quantity how to put nowhere again, realize the quantity that reduces manhole, reduce the object of taking up an area.
