Signal；
The electronic lock is coupled to timing unit and opened in response to open signal, and the ventilation unit is in response to trigger signal
Work.
By using above-mentioned technical proposal, when being provided for reserving enough to the ventilation unit in casing of timing unit
Between, realize ventilation effect because oily top layer oil liquid temperature timing is not reaching to preset temperature, but indoor temperature for
For people be in the condition of high temperature, so before entry be preferably ventilation once.
Improved as of the present utility model, the ventilation unit includes the air inlet fan and air-out wind being arranged on casing
Fan.
By using above-mentioned technical proposal, air inlet fan and air-out fan setting makes ventilation ventilation effect more preferably.
Improved as of the present utility model, the air inlet fan and air-out fan are oppositely arranged on casing.
By using above-mentioned technical proposal, air inlet fan and air-out fan are oppositely arranged on the both sides of casing, operationally
Cross-ventilation is formed, makes ventilation effect more preferably.
In summary, the utility model has the advantages that：Transformer is that temperature is raised in box for box-type transformer substation
Main cause, and the temperature of oily top layer has detected that transformer has top since can directly influencing the service life of transformer, institute
The oil liquid temperature of layer, and by temperature sensor output temperature signal, controller passes through a preset signals when receiving temperature signal
To compare with temperature signal, when temperature signal is big, the temperature overheating of oily top layer, the indoor temperature of so covert explanation are represented
Also it is too high, by ventilation unit to indoor air-changing, play cooling effect, as oil immersed type transformation oily top layer safe temperature 95
DEG C, therefore preset temperature can be set to 90 DEG C, reserved certain space, due to being all high pressure or superelevation in box-type substation
Electrical equipment is pressed, the safety coefficient of general lock is not high, so using electronic lock, to increase the safety coefficient of box-type substation.
