A three-phase dry-type transformer with anti-theft function

Abstract

The invention provides a three-phase dry-type transformer with an anti-theft function, which belongs to the technical field of anti-theft devices for transformers, and solves the problem that the door of the existing protection box is usually only equipped with a common lock cylinder, so that it is easy to be used by thieves. Crack, and then reduce the problem of the reliability of protection box, comprise: box body, box door is installed at the doorway of described box body, and transformer main body is installed on the inner bottom end surface of box body. In the present invention, through the setting of the door opener and the pressing mechanism, when the thief wants to steal the copper core inside the transformer main body, the thief first needs to open the box door, and the box door is provided with a simulated key opening, and the thief will have a Simulate the key opening to crack, but the simulated key opening cannot open the box door, which adds trouble to the thief. When the thief finds the existence of the pressing mechanism, the pressing mechanism needs special door opening parts to drive the rotation, so it is not easy It was cracked by thieves, thereby improving the reliability of the protection box.

Description

technical field [0001] The invention belongs to the technical field of anti-theft devices for transformers, and more specifically relates to a three-phase dry-type transformer with an anti-theft function. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. [0003] For example, application number: CN201911069043.4 The present invention discloses an anti-theft transformer, which includes a transformer body and steel legs, and one or more first cavities are arranged in the legs, and the lower side wall of each first cavity There is an opening, and there is a thermite flux that can move up and down in the opening. An ignition rod is arranged i...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a three-phase dry-type transformer with anti-theft function to solve the problem that the door on the existing protection box is usually only equipped with a common lock cylinder, which can be easily cracked by thieves. , thereby reducing the reliability of the protection box, and the bolts connected to the existing transformer top cover are also easily disassembled, which further increases the probability of the copper core inside the transformer being stolen, and the existing protection box on both sides of the outside Vents are usually provided for ventilation, and the vents are easily blocked by external spider webs and other blockages, thereby reducing the ventilation effect of the protection box.
