Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for purposes of illustration only and are not intended to limit the scope of the present invention.

As shown in fig. 2, the utility model discloses a can fill into power equipment box of anti-oxidant gas, including can realizing totally enclosed box body 1, still including setting up inflation inlet 6 and relief port 7 on the box body, the box body still is connected with detachable heat abstractor, and heat abstractor includes fin 5, and the both ends of fin 5 are linked together with the inside of box body through trachea 8, 9 respectively, are provided with gas drive device 4 on the trachea, and gas drive device 4 is used for driving the inside gaseous circulation flow at trachea, fin and box of box body. In the embodiment, the gas filled in the inflation inlet is nitrogen, certainly, inert gas can be adopted, as long as the purpose of oxygen expelling can be achieved, the gas driving device adopts a fan, so that the installation is convenient, and meanwhile, the energy and the electricity are saved; the air pipe adopts the copper pipe with good sealing performance and excellent heat dissipation performance.

As a further improvement, the box body is provided with an air pressure measuring device 2, the embodiment adopts a pressure gauge, the tightness of the box body can be monitored, and external moisture is difficult to enter the box body as long as internal air is in a positive pressure state.

The application process of this embodiment is as follows: when the box is used, the door handle 3 is closed to enable the box body 1 to be a closed body, the air release port 7 is opened at the moment, nitrogen is filled through the air filling port 6, internal air is discharged through the air release port 7, the air release port 7 is closed after the nitrogen is finished, the nitrogen is continuously filled, when the pressure gauge displays micro positive pressure (about 1.2 Mpa), the fan is started to guide the nitrogen in the box body into the air pipe 8 from the top, the heat is dissipated through the cooling fins 5, and then the nitrogen circulates back to the inside of the box body through the air pipe. The radiating fins can be placed at the lower temperature positions such as nearby cable ducts and the like to improve the radiating effect.

The fully-sealed nitrogen-filled box body is adopted, original devices and materials in the box body are isolated from oxygen, so that oxidation corrosion of internal original materials is delayed, and the possibility of heating of terminals and cable joints due to the increase of oxidation corrosion resistance is particularly reduced; install its leakproofness can be kept watch on to big manometer on the box, as long as inside nitrogen gas is the outside moisture of malleation state and hardly gets into in the box, high-purity nitrogen gas humidity itself is extremely low, avoids the condensation to form completely, and this patent has increased the fin simultaneously and has made the heat energy of inner member production in time effluvium.

As a further improvement, the air pressure measuring device 2 may also be directly connected to a pressure abnormality alarm device, and when the internal pressure is abnormal, the pressure abnormality alarm device may directly send out alarm signals including sound, light, electricity, and the like, so as to draw attention of workers and process the alarm signals. As shown in fig. 3, as one implementation manner, a structure of an electric contact pressure gauge 10, a power supply 11 and an alarm 12 may be adopted, the position of the electric contact may be adjusted, and when the pressure reaches a certain critical value, the gauge needle is set to be connected with the electric contact, so that the trigger circuit is connected, and the alarm gives an alarm. The pressure anomaly alarm device is considered to be common equipment in the field of pressure detection, and other implementation modes are not described herein again.
