Abstract

A liftable multipurpose 10kV switch and PT transfer trolley comprises a frame, which includes a right beam and a left beam. The right beam and the left beam are connected through a connecting piece. Atray is arranged between the right beam and the left beam, the tray is connected with the right beam and / or the left beam through a lifting mechanism, and the tray can be raised to the top of the right beam and the left beam or lowered to the bottom of the right beam and the left beam in a vertical direction through the lifting mechanism. The invention aims to solve the technical problem that theexisting switch transfer trolley cannot greatly make a switch drop to a height close to the ground and it is difficult to smoothly push the switch transfer trolley to the ground.

Description

technical field [0001] The invention belongs to the field of electric power maintenance facilities and equipment, and in particular relates to a liftable multipurpose 10kV switch and a PT transfer trolley. Background technique [0002] High-voltage switchgear is an important part of power transmission and distribution. It is an important power transmission and distribution equipment in the power industry. It is closely related to the development of the national economy and society. In recent years, my country's high-voltage switchgear manufacturing industry has developed rapidly. Safety has always been a test for the safe operation and maintenance of the switch. With people's concept of safety, great changes have taken place, with a high emphasis on human subjectivity, human needs, and human protection. Therefore, the safety and reliability of the equipment are raised to a higher level. [0003] The patent document whose application publication number is CN107732735A disclos...
