Technical Field
The invention relates to the technical field of pole-mounted transformer installation, in particular to an auxiliary device and an installation method for pole-mounted transformer installation.
Background
Power transformers are one of the main devices of power plants and substations, and are devices for transforming an alternating voltage (current) of a certain value into another voltage (current) of the same frequency or different values. When the primary winding is energized with an alternating current, an alternating magnetic flux is generated, and the alternating magnetic flux is magnetically conducted through the iron core, so that an alternating electromotive force is induced in the secondary winding. The level of the secondary induced electromotive force is related to the number of turns of the primary winding, i.e. the voltage is proportional to the number of turns. The main function is to transmit electric energy.
The transformer has the function of not only increasing voltage to transmit electric energy to an electricity utilization area in many aspects, and therefore the transformer needs to be erected and installed and is called a pole-mounted transformer.
The pole-mounted transformer generally utilizes staple bolt and mounting bracket cooperation to install between the two poles, during the installation, fix the staple bolt on two poles earlier, put up the mounting bracket on the staple bolt again, utilize the loop wheel machine slowly to hang the transformer to the mounting bracket on then, and install, the installation process is wasted time and energy, need the support of a large amount of manpower and materials, and because transformer self weight, at the in-process that the transformer lifted by crane, must the operation loop wheel machine of careful wing, just can avoid the transformer to fall, injure personnel by a crashing object.
