It is outdoor that the housing of box-type substation is placed on, and in the time of summer, under the sun is exposed to the sun, can cause the case temperature of box-type substation too high, at this moment, if untimely cooling easily causes the damage of equipment of the enclosure interior of box-type substation.This just need to carry out cooling to the housing of box-type substation, at present, the housing of existing box-type substation generally comprises casing, top cover, water pump, the shower nozzle that inside has cavity, described top cover is fixed on casing and with casing and forms sealing, be provided with dividing plate in described casing, described dividing plate is separated into two quite upper plenum and the lower cavitys of sealing with the cavity in casing, and cooling fluid is housed in upper plenum, the outlet of water pump is connected with shower nozzle, and the outlet of shower nozzle is towards cabinet exterior.When the cabinet exterior excess Temperature, water pump is opened, and the cooling fluid in upper plenum is sprayed by shower nozzle by water pump, thereby lowers the temperature to cabinet exterior.After a period of time, the liquid level of the cooling fluid in upper plenum reduces when pump working, and water pump just can't normally use, and so just needs the user to pay close attention at any time the height of the liquid level in upper plenum, and usage comparison is inconvenient, and fail safe is relatively poor.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed the warning device that in a kind of box type transformer station shell, cooling fluid lacks, and this warning device has the characteristics of the very few energy of the cooling fluid automatic alarm in box type transformer station shell.
the purpose of this utility model can realize by following technical proposal: the warning device that in a kind of box type transformer station shell, cooling fluid lacks, the housing of described box-type substation, comprise that inside has casing and the top cover of cavity, described top cover is fixed on casing and with casing and forms sealing, be provided with dividing plate in described casing, described dividing plate is separated into two quite upper plenum and the lower cavitys of sealing with the cavity in casing, cooling fluid is housed in upper plenum, it is characterized in that, described warning device comprises fluid level controller, PLC Programmable Logic Controller and alarm bell, described PLC Programmable Logic Controller is fixed on top cover, described fluid level controller is arranged in upper plenum, described alarm bell is fixed on cabinet exterior, described alarm bell and the fluid level controller circuit by separately respectively are connected with described PLC Programmable Logic Controller, the lower end of described fluid level controller and the distance between dividing plate are 5 to 10cm.
This box type transformer station shell also comprises water pump, shower nozzle etc., and the import of water pump is connected with cooling fluid in upper plenum by pipe, and the outlet of water pump is connected with shower nozzle, and the outlet of shower nozzle is towards cabinet exterior.When the cabinet exterior excess Temperature, water pump is opened, and the cooling fluid in upper plenum is sprayed by shower nozzle by water pump, thereby lowers the temperature to cabinet exterior.When pump working after a period of time, the liquid level of the cooling fluid in upper plenum reduces, when this liquid level during lower than the lower end of fluid level controller, fluid level controller passes to the PLC Programmable Logic Controller with information, the PLC Programmable Logic Controller passes to alarm bell with information again, thereby the unlatching alarm bell, alarm bell sends chimes of doom, and reminding user in time replenishes cooling fluid to upper plenum.
In the warning device that cooling fluid lacks in above-mentioned box type transformer station shell, described alarm bell is fixed by screws on cabinet exterior.
In the warning device that cooling fluid lacks in above-mentioned box type transformer station shell, the inwall place of described casing offers the holddown groove that several have internal thread from top to bottom successively, and the cross section of described holddown groove is rounded.
In the warning device that cooling fluid lacks in above-mentioned box type transformer station shell, be fixed with brace on described fluid level controller, the described brace other end is fixed by screws in one of them above-mentioned holddown groove.
Compared with prior art, the utility model passes to the PLC Programmable Logic Controller by the fluid level controller that is arranged in upper plenum with information, the PLC Programmable Logic Controller passes to alarm bell with information again, thereby unlatching alarm bell, alarm bell sends chimes of doom, reminding user in time replenishes cooling fluid to upper plenum, improves usage safety performance.
