Background
Transformer substation, place of changing voltage. In order to transmit the electric energy generated by the power plant to a remote place, the voltage must be increased to become high voltage, and then the voltage is decreased as required near the user, and the voltage increasing and decreasing work is completed by a transformer substation. The main equipment of a substation are switches and transformers. The small transformer substations are called as transformer substations according to different sizes. The transformer substation is larger than the substation. The transformer substation refers to a step-down transformer substation with the voltage grade below 110kV, and comprises step-up and step-down transformer substations with various voltage grades.
The equipment of the transformer substation is mostly connected by adopting a wiring board, and the wiring board adopted by the transformer substation (substation) has two fixed specifications most commonly: one is that the four threaded holes are spaced by 40 mm; the other is 50mm by 50 mm. When daily overhaul and maintenance are carried out on the equipment in spring and autumn every year (such as overhaul and maintenance of a main transformer, a capacitor voltage transformer, a lightning arrester and the like), the wiring board needs to be detached in advance, and the wiring board needs to be installed again after the daily overhaul and maintenance are finished; if the screw rod is corroded and the screw hole of the wiring board is not aligned, the traditional wrench is time-consuming to use; even if the safety belt is worn when the safety belt is detached and installed by standing on equipment (the height of the equipment generally exceeds two meters and exceeds the specification of national standard GB/T3608-2008 high-altitude operation classification), workers need to pay extra attention to safety, the safety belt is detached and installed by two hands together, the related equipment cannot be held, the operation process needs to be careful, and objects fall from high altitude sometimes.
