As a key facility for voltage conversion, the core function of Box Type Transformer is to step up or down the electricity generated by the power plant to meet the needs of long-distance transmission and users. Its core equipment includes switches and transformers. According to the size, substations can be divided into substations and transformer substations. Substations usually refer to step-down substations with voltage levels below 110KV, while transformer substations cover "step-up and step-down" substations of various voltage levels.
my country has formulated clear regulations for the distance between Box Type Transformer and buildings. For example, for substations of 10KV to 35KV, the distance between the front and residential houses should be at least 12 meters, and the side should be at least 8 meters. If it is a substation of 35KV and above, the front distance from residential houses shall not be less than 15 meters, and the side distance shall not be less than 12 meters. In addition, the distance between Box Type Transformer and residential houses shall also be more than 5 meters. It is particularly pointed out that the radiation safety distance of 110KV substations must exceed 300 meters, and should not be built near sensitive buildings such as residential houses or kindergartens.
For safety considerations in general practice, the distance between the Box Type Transformer and the house should be kept at least 5 meters to ensure safety. This distance requirement is mainly for transformers with voltages below 10 kV. If the transformer is located in densely populated areas such as factories, mines, towns, etc., although it can be slightly smaller than the above regulations, sufficient safety distance should still be guaranteed.
Relevant laws and regulations clearly stipulate the scope of the power line protection zone, which includes the area within two parallel planes formed by the conductor edge extending horizontally outward and perpendicular to the ground. For voltages below 10 kV, the extension distance of the conductor edge should be 5 meters.
For safety reasons, maintaining a sufficient distance is to prevent harm to the house and the people in it due to transformer failure or improper operation. Although electromagnetic radiation will not cause direct harm to the human body, too close a distance may still cause safety hazards, such as electric shock, fire, etc.
In the face of special situations, in densely populated areas such as factories, mines, towns, etc., due to space limitations, it may not be possible to fully follow the above regulations. In this case, you should consult a professional power department or organization to determine a reasonable safety distance based on the actual situation. The extension distance of the conductor edge of each voltage level should not be less than the sum of the horizontal distance of the conductor edge after the maximum calculated sag and the maximum calculated wind deviation and the safety distance from the building after the wind deviation. And ensure that the distance is not less than the minimum safety distance stipulated by the state.
For safety awareness, the distance between the Box Type Transformer and the house should be kept at least 5 meters to ensure safety. In special circumstances, you should consult a professional organization and determine a reasonable safety distance based on the actual situation.
