Total-buried nonmetal casing prefabricated type intelligent transformer station

Abstract

The invention relates to a high-voltage transformation device, and especially relates to a total-buried nonmetal casing prefabricated type intelligent transformer station. The total-buried nonmetal casing prefabricated type intelligent transformer station comprises a casing, and a high-voltage cabinet, a low-voltage cabinet and a transformer which are installed in the casing. The casing is also internally provided with an automatic control system, a contraction ladder and a cable chamber. The transformer is provided with a high-voltage inlet wire unit, a low-voltage inlet wire unit and a grounding unit. The upper portion of the casing is provided with a casing cover, the four corners of the top portion of the casing are provided with water collecting boxes, the water collecting boxes are provided with landscape ventilating ducts, the water collecting boxes are also internally provided with automatic closing devices, the bottom of the casing is provided with a steel bottom frame, the bottom surface of the casing is provided with a water collecting groove, and an emergency drainage apparatus is arranged between the water collecting groove and the steel bottom frame. The total-buried nonmetal casing prefabricated type intelligent transformer station is scientific and reasonable in design, high in innovation, stable in equipment operation, high in safety and reliability and long in service life, beautifies environment and can also guarantee ventilation and heat dissipation of the transformer station.

Description

technical field [0001] The invention relates to a high-voltage substation equipment, in particular to a fully buried non-metal box body pre-installed intelligent substation. Background technique [0002] The pre-installed substation is an indispensable and important part of the power system. It is sent to the load center by 10KV or 20KV medium voltage as the transmission and distribution voltage. After the pre-installed substation is transformed into 220 / 380 volts, the low-voltage voltage is sent to the user. The type can mainly ensure the stability of the user's voltage, reduce line loss, reduce voltage drop, and improve the quality of power supply. This type of substation device has brought many benefits to power supply and consumption, and is currently the best form of power distribution in the world. [0003] However, a large number of pre-installed substations, switch stations, and ring network cabinets have brought uncoordinated contradictions to the surrounding enviro...

Problems solved by technology

[0003] However, a large number of pre-installed substations, switch stations, and ring network cabinets have brought uncoordinated contradictions to the surrounding environment. There have been contradictions between the supporting facilities for power consumption and the installation environment, the contradiction between the supporting facilities and the safety of the living environment, and the contradiction between the supporting devices and the environment. The contradiction of beautifying and greening the urban environment, although the box-type substations on the ground have made some beautification decorations on the appearance or decorated the surroundings with some billboards or fences, it still has a certain impact on the surrounding environment. Not only does it not coordinate with the surrounding area, but it also affects the safety of human settlements, such as the noise and radiation generated by the box-type substation, which affects people's view, etc. Each pre-installed box-type substation will occupy a large piece of land

[0004] At present, the technology suitable for underground use of fully buried substations is not yet mature: the heat dissipation and ventilation are not smooth, the heat cannot be dissipated, and there are potential safety hazards. Blindly improving the insulation grade of transformer insulation materials will inevitably increase the cost of the transformer, and its service life will also decrease. Another method is to install heat dissipation and ventilation windows on the surface. In case of rainy and snowy weather, if no corresponding rain-shielding and drainage measures are taken, rainwater will easily enter the box and affect the safe and normal operation of the equipment; Putting it underground for a long time will cause condensation inside, which will also affect the safe operation of the equipment, and in severe cases cause equipment damage
