The invention relates to the technical field of connection terminals, in particular to a box-type combined total terminal box for a secondary line collection terminal of a 220kV novel composite apparatus. A semaphore collection terminal block, a partition plate, secondary line collection terminal blocks of a current transformer, a heater, a DC bus bar and DC air switch, AC bus bars, an AC air switch and a headlamp are arranged in a box body; and the box body is total terminal box formed by combining two parts of box bodies in which the same equipment is internally arranged. According to the box-type combined total terminal box, the semaphore of split-phase equipment is collected into the terminal box, so that the field construction workload is reduced, the technical difficulty of construction is lowered and the consumable materials are saved. Meanwhile, the box-type combined total terminal box has the beneficial effects that the box-type combined total terminal box has rainproof and moisture-proof functions, the temperature of the box body can be automatically adjusted and controlled, cable connection is facilitated, the field construction workload is reduced, the technical difficulty of construction is lowered and the consumable materials are saved. The power requirements of the split-phase equipment can be met, the power supply stability of an AC system is ensured, AC in a field region is designed according to loop network power supply, interval completion of an AC/DC loop network is facilitated and the power supply system is stable and reliable.
