Description

Transformer replacement platform for closed switchgear

technical field

The utility model relates to an auxiliary device for replacing transformers of closed switch cabinets, in particular to a replacement platform for transformers of closed switch cabinets.

Background technique

With the development of science and technology, closed switchgear has been widely used in power systems due to its characteristics of good dynamic and thermal stability, high protection level, small footprint, convenient operation and maintenance, and high reliability. However, due to the small internal space of the closed switchgear, the current and voltage transformers are the main electrical equipment, and their own weight is relatively heavy, about 30-70 kg, which brings difficulties to installation and disassembly. At present, the common practice is to hang the transformer on the support with the help of ropes, or use a jack to lift the transformer and install it on the support. Because it is not easy to fix firmly, the safety is poor, and it is time-consuming and laborious.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a closed switch cabinet transformer replacement platform, which can make the position adjustment easier when the closed switch cabinet replaces the transformer, and is fixed firmly, greatly improving Improve work efficiency while ensuring personnel safety.

The transformer replacement platform of the closed switch cabinet described in the utility model includes a chassis, a turbine, a worm rod, a rotating handle, a fixed plate, a transmission rod, a supporting connecting rod, a supporting panel, a fixing strip, a locking buckle, a supporting frame and a ground wheel composition. The chassis is the main body support of the utility model, and the ground wheels for grounding are provided at the inward positions of the four corners below the chassis. On the chassis, the rear part is provided with a fixed plate, the front part of the fixed plate is provided with a worm gear, the middle part of the fixed plate is provided with a worm meshed with the worm gear, and the upper end of the worm screw is provided with a rotating handle. The turbine connection is provided with a transmission rod protruding forward, the front end of the transmission rod is connected to the lower end of the support link, and the upper end of the support link is connected to the support panel, and the support panel is provided with fixing strips around it. At the slightly backward position of the front part of the chassis, a support frame in the form of a door frame is provided, and said support frame is arranged as a casing structure. On one side of the thick tube at the lower end of the support frame, a locking buckle is arranged. After the transformer is fixed on the support panel, the rotating handle is operated to drive the transmission rod to raise or lower the height of the support panel through the engagement of the worm rod and the turbine, so that the transformer fixing hole is consistent with the installation position of the switch cabinet, which is convenient for installation and disassembly. In the transformer replacement platform of the closed switch cabinet described in the utility model, a through hole is opened on one side of the fixing plate for the rotating handle and the worm rod to pass through, and a hole for passing the fixed turbine fixing pin is opened on one side. There are length-adjustable fixing strips installed around the support panel, which can fix transformers of different sizes.

The closed switch cabinet transformer replacement platform described in the utility model has a simple overall structure and is easy to operate and use. By adjusting the length of the fixing bar, it is suitable for fixing transformers of various sizes. Work safety; through flexible control of the height of the support panel, it can meet the needs of different installation positions in the switch cabinet, and help the staff quickly adjust the gap between the transformer fixing hole and the installation position of the switch cabinet, thus greatly reducing the working time and labor intensity.
