The invention provides a shield tunneling machine and a substation thereof so as to solve the problem that since heat gathered on a transformer cannot be released in time, the service life of the transformer is reduced. The shield tunneling machine substation comprises a box body and the transformer arranged in the box body. The box body is provided with an air inlet and an air outlet. The shield tunneling machine substation comprises a box body temperature control device and a transformer temperature control device. The box body temperature control device comprises a box body blower fan. The transformer temperature control device comprises a transformer blower fan. According to the shield tunneling machine substation, the heat in the box body can be discharged in time via the air outlet through the box body blower fan, and meanwhile, cold air can enter the box body via the air inlet; the transformer blower fan can transmit the heat in the transformer to the box body in time; and the box body temperature control device can control the box body blower fan to start or stop and the transformer temperature control device can control the transformer blower fan to start or stop, thereby realizing a purpose of automatic temperature control and preventing the problem that the service life of the transformer is reduced since the heat is gathered on the transformer.
Description
technical field [0001] The invention relates to a shield machine and a substation thereof. Background technique [0002] With the application and continuous development of the shield machine, the demand for the onboard prefabricated substation of the shield machine is also increasing, and the technology of the prefabricated substation is becoming more and more mature. There are still deficiencies in the ventilation and heat dissipation of prefabricated substations. If the heat in the substation cannot be released in time, it will affect the normal operation of the transformer in the substation and shorten the service life of the transformer. [0003] The substation in the prior art usually includes a box body, which is provided with an air inlet and an air outlet. The transformer is located in the box body, and a box fan is installed at the air outlet of the box body. The air flows through the air, and the heat in the box is transferred to the outside of the box through th...
