Referring to fig. 1 to 5, the present embodiment provides a cooling system for a transformer substation, where a plurality of switch cabinets 1 are disposed in the transformer substation, and each switch cabinet 1 is provided with an infrared temperature measurement window 101. The cooling system comprises a ground guide rail 2, a sliding contact line power supply device and a cooling robot.

specifically, the working principle of the cooling system for the transformer substation is as follows:
Firstly, synchronously getting electricity from the trolley line power supply device in the process that the cooling robot moves along the ground guide rail 2;
secondly, when the infrared temperature measuring probe 5 moves along the ground guide rail 2 along with the cooling robot, synchronously measuring the temperature of the infrared temperature measuring window 101 on each switch cabinet 1 passing by the infrared temperature measuring probe and recording the temperature of each switch cabinet 1;
Comparing all temperature numerical values that cooling robot obtained to find out the cubical switchboard 1 that the temperature is the highest, mobile device 3 moves the position department that corresponds to the cubical switchboard 1 that the temperature is the highest and stops, and electronic flexible tuber pipe 6 stretches out and aims at this cubical switchboard 1, and air-cooler 4 starts, directly carries out the pertinence cooling to the cubical switchboard 1 of highest temperature.
preferably, the cooling robot moves periodically along the ground rail 2, for example, a cycle is performed every 15min, so as to monitor the temperature of each switch cabinet 1 in an unattended state for 24 hours.
Of course, the switch cabinet 1 at the highest temperature is not cooled, but a temperature threshold value is set, and when the temperature of the switch cabinet 1 detected by the cooling robot exceeds the threshold value, the electric telescopic air duct 6 is immediately extended out and the air cooler 4 is started to cool.
it can be understood that the cooling system for the transformer substation adopts a targeted cooling means, so that the cooling effect is remarkable.
preferably, the moving device 3 comprises a supporting platform 301, a guide wheel 302, an inspection motor 303 and a power wheel 3043 set 304. The supporting platform 301 is located below the air cooler 4 and is fixedly connected with the air cooler 4. The guide wheel 302 is located at the central position of the bottom of the supporting platform 301 and is connected with the ground guide rail 2 in a rolling way.

The belt pulley 3041 is in transmission connection with the driving shaft of the inspection motor 303 through the first belt. The two wheel shafts 3042 are in transmission connection through the second belt, wherein one wheel shaft 3042 is in transmission connection with the inspection motor 303 through the belt pulley 3041. Each wheel shaft 3042 is fixedly connected with two power wheels 3043.
in this embodiment, the ground rail 2 is made of i-shaped steel with an i-shaped cross section, and the guide wheel 302 is a concave wheel matched with the ground rail 2. Further, the ground guide rail 2 is made of 20mm wide I-shaped steel and is arranged on the periphery of the switch cabinet 1 in the transformer substation.

When the mobile device 3 starts to operate at the initial position, the photoelectric correlation positioning device 3045 is blocked by the ground guide rail 2, when the robot moves to the position of the switch cabinet 1, the photoelectric correlation positioning device 3045 receives a signal through the positioning hole on the ground guide rail 2 and transmits the signal to the control device, and the control device immediately decelerates the mobile device 3, the inspection motor 303 and reduces the moving speed of the robot. When the signal sensed by the photoelectric correlation positioning device 3045 disappears again, the control device immediately stops the mobile device 3 polling motor 303 and locks the robot at the current position by the electronic brake device, so as to complete the alignment work of the infrared temperature measuring probe 5 and the infrared temperature measuring window 101.

it can be understood that when the electric telescopic air duct 6 extends outwards and presses the travel switch 703, the travel switch 703 is pressed down, the start-stop motor 702 is turned on and off, and the explosion-proof glass baffle 701 is turned to the opening angle of the infrared temperature measurement window 101; after the air cooler 4 is started, cold air can be blown into the switch cabinet 1 from the infrared temperature measurement window 101, and therefore the rapid cooling inside the switch cabinet 1 is achieved. When the temperature is reduced, the electric telescopic air pipe 6 retracts, the travel switch 703 resets, and the start-stop motor 702 drives the explosion-proof glass baffle 701 to reset to the angle for shielding the infrared temperature measurement window 101, so that small animals are prevented from entering and exiting the switch cabinet 1.
preferably, the electric telescopic air duct 6 comprises a steel ring 601, an electric telescopic rod 602 and a telescopic rubber hose 603. One end of the electric telescopic rod 602 is fixedly connected with the steel ring 601, and the other end of the electric telescopic rod is fixedly connected with the air cooler 4.

This heating phenomenon is not normal but is difficult to avoid completely. When the equipment heating phenomenon appears, the robot can be under the condition of unmanned intervention, and the automatic removal equipment department that generates heat to cool down the processing to equipment, make equipment can not burn out because of overheated, improved equipment reliability, ensured power supply reliability.
2. with strong pertinence
A high-power air conditioner is generally arranged in a 10kV high-voltage chamber of a transformer substation, but the pertinence is not strong, the sealing performance of a switch cabinet 1 is relatively strong, and the internal air circulation is not smooth, so that the cooling effect of the conventional high-power air conditioner on the local and short-time overheating phenomenon of the switch cabinet 1 is not obvious. The cooling system for the transformer substation has the characteristic of strong pertinence, and can continuously and efficiently cool heating equipment.
