Description
Technical field
The utility model relates to casees to become technical field, and in particular to a kind of improvement structure of box-type substation.
Background technique
Box-type substation, which is called, does prepackage type electric substation or preassembled transformer station, and abbreviation case becomes.Box-type substation is a kind of
High-tension switch gear, distribution transformer and low-voltage distribution equipment, are lined up that integrated prefabrication is indoor, family by certain connection plan
Outer close-coupled controller switching equipment, i.e., organically combine the functions such as transformer pressure-reducing, low-voltage distribution, is suitable for Urban Net Construction
It is a kind of brand-new substation to emerge after civil engineering transformer station with transformation.Box-type substation is widely used in mine, work
Enterprise of factory, oil gas field and wind power station.
Box-type substation for wind power station is usually provided with oil trap in the bottom of box to collect, such as oil immersed type
The accident oil that transformer is revealed when breaking down.In order to check level condition oily in oil trap, the oil-collecting that existing case becomes in time
Slot uses unenclosed construction.Although the unenclosed construction of oil trap is conducive to heat dissipation and convenient for checking inner case, when raining,
Rainwater can equally enter in oil trap.On the one hand, water-oil separating difficulty is increased after the mixing of rainwater and grease, improves the later period
On the other hand maintenance cost after rainwater could quickly fill up oil trap, the accident oil accumulated in oil trap is taken out of together, become to case
Context cause seriously to pollute.
Utility model content
The purpose of this utility model is to provide a kind of improvement structures of box-type substation, to solve the change of prior art raising middle flask
The oil trap of unenclosed construction can be mixed into rainwater when rainy, high so as to cause later period water-oil separating complex process, maintenance cost,
And rainwater takes accident oil the problem of out of causing environmental pollution.
The utility model is achieved through the following technical solutions：
A kind of improvement structure of box-type substation, including cabinet and the oil trap being located under the box, the tank floor
It is provided with opening, is provided with flase floor in the opening；Oil-collecting section, the oil-collecting section are provided between the cabinet and oil trap
Upper end is connected to by opening with the inside of cabinet, and oil-collecting section lower end is connected to inside oil trap；It further include oil well pump, the oil well pump
By being connected to inside petroleum pipeline and oil trap.
The existing case accommodation for wind power generating set often by oil trap below be set as unenclosed construction so as to
The level condition of accident oil in oil trap is observed in staff.But setting can be led to the problem of in this way.When rainy, rainwater
It can directly enter in oil trap from the opening of oil trap and be mixed with accident oil.On the one hand, rainwater and accident oil respectively contain
Impurity causes difficulty to later period water-oil separating technique after mixing, is increased again using the process costs of accident oil, and then improve
Maintenance cost；On the other hand, rainwater accelerates oil trap to fill up process, and the accident oil filled up in rear oil trap taken out of by rainwater,
The context become to case causes seriously to pollute, and does not simply fail to recycling accident oil, it is also necessary to it is dirty to handle soil caused by accident oil
Dye.For building in river valley region wind-driven generator, arround case change be frequent to meet with rainy day.Therefore, it is necessary to existing
Box-type substation structure improve be suitable for river valley region wind-driven generator.
Specifically, like the prior art, box-type substation provided by the utility model also include cabinet and be located at cabinet
The oil trap of lower section is provided with opening on the bottom surface of cabinet, is provided with flase floor in the opening.Work is used for above flase floor
The standing of personnel and placement transformer equipment such as oil-immersed transformer.Opening neglect specific requirements greatly depending on, it is preferable that case
Body bottom surface is entirely open end, and flase floor is arranged in open end.The advantage of flase floor is not only there is basic power
It learns performance to stand and each transformer equipment with support personnel, while the through-hole opened up thereon can allow for accident oil quickly to flow to case
Below body.Preferably, the material of flase floor can be steel or aluminium.Oil trap below cabinet is for storing accident oil.
Oil-collecting section is provided between cabinet and oil trap, oil-collecting section upper end is connected to by opening with the inside of cabinet, oil-collecting
The inside of section lower end connection oil trap.By above structure, when causing an accident oil, accident oil is dropped down onto from the flase floor of tank floor
It is collected in oil-collecting section, is eventually entered into oil trap store by oil-collecting section bottom end under gravity later.As cabinet, collection
A kind of preferred deployment of oily section and oil trap, cabinet and the flase floor side of resting on the ground, oil-collecting section and oil trap are located at ground
Below face, for the oil trap in ground not by direct sunlight, temperature is lower compared with the temperature in cabinet, the accident oil in oil trap
It is less prone to the extreme cases such as burning.
Further include oil well pump, oil well pump connects oil trap by petroleum pipeline, the accident oil for will be stored in oil trap from
It is detached in oil trap.Preferably, access port of the petroleum pipeline on oil trap is located on the side wall of oil trap.
The principles of the present invention are：When the transformer equipment in cabinet breaks down, when causing an accident oil, accident oil passes through
Flase floor drops down onto oil-collecting section, and later, the accident oil fallen in oil-collecting section continues to move to eventually fall into collection under gravity
It is collected in oil groove.
In above structure, accident oil quickly leaves cabinet by flase floor, avoids accident oil and accumulates in cabinet and causes
Security risk；Meanwhile be connected to cabinet at the top of oil trap by oil-collecting section, form enclosed construction, rainwater will not directly into
Enter in oil trap and mixed with accident oil, accident oil is stored in oil trap to more than after safety levels, can be incited somebody to action by oil well pump
Accident oil is extracted out from oil trap, and needs not move through water-oil separating etc. complicated separating technology can be put back into, significantly
Reduce maintenance cost；In addition, the accident oil in oil trap will not be taken out of by rainwater, be conducive to the environmental protection that case becomes surrounding,
With extensive promotional value.
