How to fix the transformer on the column

A, the basic requirements of transformer fixed on the column

The fixing of the transformer on the column should meet the following basic requirements: first, the structure is stable and can bear the weight of the equipment itself and external loads such as wind, ice and snow; Second, it is convenient for installation and maintenance; Third, it has good anti-loosening and anti-shock performance to avoid safety accidents caused by bolt loosening caused by vibration; Fourth, it has certain anti-theft and anti-sabotage capabilities.

Second, the common fixing methods and steps

1. Tower selection and foundation treatment

Before installing the transformer on the pole, you should first choose the pole that meets the bearing requirements. Generally, concrete poles or steel poles are selected, and the pole foundation should be firm, and reinforcement should be carried out when necessary to prevent the pole from tilting or sinking.
　　. Install the cross arm and bracket
　　he cross arm is an important structural member for supporting the transformer, usually made of angle steel or channel steel. The cross arm should be firmly fixed on the pole and kept level. For large-capacity transformers, double cross arms or reinforced cross arms can be used to enhance the support capacity.

3. Fix with U-bolts or hoops.

The transformer body is usually fixed on the cross arm by U-bolts or special hoops. Bolts should be made of high-strength hot-dip galvanized materials to enhance corrosion resistance. During installation, attention should be paid to the tightening torque of bolts to prevent the cross arm from being deformed due to over tightening or the equipment from shaking due to over loosening.

4. Install shockproof pad and anti-loosening device.

In order to reduce the vibration caused by current shock or wind force during operation, a shockproof gasket should be installed between the transformer and the cross arm. At the same time, add a spring washer or lock nut at the bolt joint to prevent it from loosening and falling off.

5. Grounding and safety protection
　　Transformer shell must be reliably grounded to ensure the safety of maintenance personnel and the normal operation of equipment. In addition, warning signs should be set up to prevent human touch by mistake; In densely populated areas, it can also be considered to install protective covers or isolation nets.

III. Matters needing attention and maintenance requirements

During the installation, the operation shall be carried out in strict accordance with relevant national standards and design drawings. After the installation is completed, an overall inspection should be carried out, including whether the fasteners are firm and whether the grounding is good. In daily operation, regular inspection should also be conducted to find and deal with problems such as looseness and corrosion in time to ensure long-term stable operation of equipment.

tag

To sum up, fixing the transformer on the column is a highly technical and responsible job. Only by strictly controlling the material selection, installation and maintenance can we ensure the safe and reliable operation of the equipment, thus providing users with stable and continuous power supply. Electric power construction personnel should constantly improve their technical level, strictly implement operating procedures, and effectively ensure the safety of power grid operation.
