A semiconductor cooling chip provides cooling, enhancing temperature control. A fan rotates, blowing air into the sliding box wall to cool the transformer and control its temperature. A dustproof and rainproof net reduces the entry of rainwater and dust into the sliding box wall during rainy days and normal times. A dustproof and rainproof rain shield is installed above the dustproof and rainproof plate to prevent rainwater from directly contacting the net, reducing the possibility of dust and rainwater entering the fan and transformer. An air outlet on the back of the sliding box wall discharges cooled air outwards. A rainproof plate reduces the possibility of rainwater entering the sliding box wall. Ventilation openings inside the sliding box wall allow ventilation to lower the transformer temperature.

[0016] 2. The present invention provides a power box for easy maintenance of electrical equipment. When the transformer needs maintenance, the limiting plate on the bottom surface of the box body is pulled open, and the descent key on the right side of the sliding box wall is pressed. The telescopic column retracts downward, and the sliding box wall slides up and down through the grooves around the perimeter and the protruding protrusions of the four support columns connected to the bottom plate of the box body. This facilitates maintenance personnel in repairing the transformer and maximizes visibility.

[0017] 3. The present invention provides an electrical box for easy maintenance of electrical equipment. Tools installed in the emergency toolbox on the left side of the sliding box wall can be used to maintain the electrical equipment. At night, four lamp posts will light up to illuminate the electrical equipment, avoiding the need for maintenance personnel to hold lamps, which could lead to accidents during maintenance.

[0018] 4. This invention provides a power box for easy maintenance of electrical equipment. A temperature controller installed on the top of the transformer monitors the transformer's temperature. By pressing the power on / off button, the maximum temperature of the transformer can be set using the temperature increase and decrease buttons. A temperature sensor is used to sense the temperature inside the sliding box wall. The transformer temperature is displayed on a temperature display screen. When the transformer temperature exceeds the set maximum temperature, an alarm horn will sound to alert electrical maintenance personnel to come and check. After maintenance is completed, pressing the increase button on the right side of the sliding box wall causes the telescopic column to retract upwards. The sliding box wall slides up and down through the grooves around its perimeter and the protruding protrusions of the four support columns connected to the bottom plate of the box.
