The invention discloses an M-type on-load voltage regulation tap switch maintenance support which comprises a supporting base, a lower rotating mechanism, an upper rotating mechanism, a supporting rod and a shooting mechanism lifting device, the lower rotating mechanism is installed on the supporting base, a curtain plate fixing plate is arranged on the lower rotating mechanism, the upper rotating mechanism is installed over the lower rotating mechanism, and a curtain plate fixing plate is arranged on the curtain plate fixing plate. The two ends of the supporting rod are connected with the lower rotating mechanism and the upper rotating mechanism respectively, and the shooting mechanism lifting device is located under the lower rotating mechanism. According to the maintenance support, the switch core body can be vertically and reliably placed after being lifted out conveniently, the core body can rotate by 360 degrees at will, and disassembly maintenance and reassembly work can be completed only by two maintainers; meanwhile, the risk that the core body rubs against the ground or is crushed is also avoided; the maintenance bracket is convenient for field installation and transportation, improves the field maintenance efficiency, and solves the problem that the field disassembly maintenance operation of the M-type on-load tap-changer is difficult.
Description
technical field [0001] The invention relates to the technical field of maintenance equipment, in particular to an M-type on-load tap changer maintenance bracket. Background technique [0002] With the development of the national economy and the rapid development of the power industry, the capacity of power equipment and the scale of the power network are increasing day by day, and people's requirements for the reliability of equipment operation in the power system are also increasing. The on-load tap-changing transformer is a very important power transmission equipment in the power system substation. It realizes the on-load voltage regulation of the high-voltage transmission and distribution grid through the step-by-step action of the on-load tap changer, and makes the industrial power supply and residential power supply system The voltage remains stable. [0003] When carrying out the maintenance test of the M-type (SHZVⅢ) on-load tap-changer, the M-type on-load tap-change...
