The utility model provides air insulated switch equipment for regulating and controlling an internal electric field, which consists of a bus chamber, a circuit breaker chamber, a cable chamber and an instrument chamber, wherein various separated chambers are separated by metal separated boards; a circuit breaker is inserted to the work position through a chassis truck; structures with internal shields are arranged in a wall bushing and a static contact box; a capacitor core rod structure in an electrified display sensor is improved; and a voltage-equalizing hood is arranged at each electrified exposed electrode part. The air insulated switch equipment has the advantages that the voltage-equalizing hoods which are specially designed and manufactured by the utility model and elements with inner shield are arranged at the strength part of a high electric field inside the equipment and are used for regulating and controlling the internal electric field, so that the insulating performance is greatly improved, the electrical air gap and the occupied area are reduced and the size of a cabinet body is greatly reduced; and the boosting and remoulding are facilitated, funds are saved and the air insulated switch equipment has a remarkable effect.
