Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to an isolation transformer. Background Technology

[0002] An isolation transformer is a transformer whose input and output windings are electrically isolated. Isolation transformers are used to prevent accidental simultaneous contact with live parts. The isolation of the transformer isolates the current in the primary and secondary windings. Isolation transformers are widely used in the electronics industry, mining enterprises, machine tools, and mechanical equipment as control power supplies for general circuits, and as power supplies for safety lighting and indicator lights. Isolation transformers are safety power supplies, generally used for machine maintenance and repair, providing protection, lightning protection, and filtering. Existing isolation transformers have undergone continuous development and improvement, resulting in low failure rates and long service lives, with no significant defects in practical use. The only drawback is that the relatively large size and weight of the transformer body make replacement inconvenient. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an isolation transformer that solves the problem that the main body of existing isolation transformers is inconvenient to replace during maintenance, replacement, and installation due to its relatively large size and heavy weight.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: an isolation transformer, including a housing and a transformer body, wherein the front end and the upper end of the housing are respectively provided with a cabinet door and a cover plate, the cabinet door is provided with a number of control buttons and instruments, and a sealing plate is fixedly installed on the lower wall of the cover plate;

[0005] The upper and lower ends of the transformer body are respectively fixedly connected to an upper beam and a lower beam. A partition is fixedly installed on the upper end of the upper beam. A pair of fixing plates are fixedly installed on the upper end of the partition. Two pairs of terminals are provided on each pair of fixing plates. The transformer body is electrically connected to four pairs of terminals.

[0006] The inner wall of the box is provided with a baffle, the baffle has an opening, and the partition is inserted into the opening.

[0007] Preferably, the inner wall of the opening is provided with two pairs of inclined inner wall surfaces, the outer wall of the partition is provided with an inclined outer wall surface, the two pairs of inclined outer wall surfaces are in contact with the two pairs of inclined inner wall surfaces respectively, and the partition is provided with two pairs of lifting lugs.

[0008] Preferably, the bottom of the box is provided with a pair of support beams, and the lower beam is fixedly installed on the pair of support beams.

[0009] Preferably, the upper end of the housing is provided with two pairs of screws, the cover plate is fitted over the two pairs of screws, and a fixing nut is screwed onto the screws and located at the upper end of the cover plate.

[0010] Preferably, the upper end of the box is provided with a lifting port, and the seal is inserted into the lifting port.

[0011] Preferably, the side wall of the enclosure is provided with several wiring ports.

[0012] This utility model provides an isolation transformer with the following advantages: an openable cover is provided at the upper end of the enclosure. When maintenance, replacement, and installation of the transformer body are required, the cover can be opened by unscrewing the fixing nut. Then, the cabinet door can be opened and the bolts between the lower beam and the support beam can be unscrewed. The transformer body below can then be lifted out of the enclosure through two pairs of lifting lugs and partitions. After maintenance is completed, the transformer body is lifted back into the enclosure, and the partitions are inserted into the baffle to form an isolation seal for the transformer body.

[0013] By separating the transformer body from the terminals using a partition, problems caused by external factors during the wiring process can be avoided. Attached Figure Description
