s3: meanwhile, when the power distribution cabinet bodies (1) are spliced and installed, the splicing mechanism (4) is clamped on the power distribution cabinet bodies (1) through the driving control of the braking mechanism (3) on the splicing mechanism (4), so that the power distribution cabinet bodies (1) are spliced firmly and stably;

s4: under the cooperation of the ventilation mechanism (5) and the sealing mechanism (6) during working, the spliced power distribution cabinet body (1) can have good ventilation and heat dissipation performance, and the power distribution cabinet body (1) can normally work.
