Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a magnetic interference-proof transformer. Background Art

[0002] A transformer is a stationary electrical device that converts alternating current (AC) energy of one voltage to another voltage through the principle of electromagnetic induction. A transformer consists of two or more windings, called the primary and secondary, wound around a common iron core. When AC current passes through the primary winding, it generates an alternating magnetic flux in the core, inducing an electromotive force (EMF) in the secondary winding. By adjusting the turns ratio between the primary and secondary windings, the output voltage can be varied.

[0003] Among them, step-up transformers are used to increase low voltage to high voltage and are commonly used in power transmission and distribution. Step-down transformers are used to reduce high voltage to low voltage and are commonly used in industrial and household power applications. In the field of power transmission, transformers are widely used in substations and transmission lines to increase or decrease voltage to meet the requirements of different distances and loads. In the industrial field, transformers are widely used in factories and enterprises to provide a stable power supply and meet the needs of various electrical equipment.

[0004] Transformers generate alternating magnetic fields during operation. If these fields are too strong or unevenly distributed, they may interfere with surrounding electronic and communication equipment. Therefore, proper design and installation are necessary to reduce or eliminate the effects of these magnetic fields. This includes installing a shielding layer such as a metal plate or mesh on the outside of the transformer to effectively block or weaken the propagation of the magnetic field, thereby reducing interference with surrounding equipment. Grounding the transformer casing and core can also divert some of the magnetic field underground, minimizing interference with the surrounding environment.

[0005] However, when connecting the grounding wire of a common anti-magnetic interference transformer, wire stripping and wiring are required, which is troublesome, especially when some transformers are installed at high places and high-altitude operations are required. In view of this, the present application proposes an anti-magnetic interference transformer. Utility Model Content

[0006] In response to the shortcomings of the existing technology, the utility model provides a magnetic interference shielding transformer with advantages such as easy installation of the grounding wire. It solves the problem that the grounding wire of the common magnetic interference shielding transformer needs to be stripped and connected when connecting, which makes the wiring more troublesome, especially when some transformers are installed at high places and need to be operated at high altitude.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a magnetic interference shielding transformer, comprising a mounting base plate, a magnetic interference shielding shell fixedly mounted on the top of the mounting base plate, a wiring internal threaded cap fixedly mounted on the bottom of the mounting base plate, a grounding pin extending into the interior of the magnetic interference shielding shell fixedly mounted on the top of the wiring internal threaded cap, a wire threadedly mounted on the bottom of the wiring internal threaded cap, a grounding rod threadedly mounted on the bottom end of the wire, and the grounding rod inserted into the ground.

[0008] Furthermore, wire noses are fixedly installed at both ends of the wire, and a connecting stud is fixedly installed on one side of the wire nose, and one of the connecting studs is threadedly connected to the internal threaded cap of the wiring.

[0009] Furthermore, a grounding internal thread cap is fixedly installed on the top of the grounding rod, and the grounding internal thread cap is threadedly connected to another connecting stud.

[0010] Furthermore, a mounting base block is fixedly installed on the bottom of the mounting base plate, and a connecting base plate is fixedly installed on the bottom of the mounting base block.

[0011] Furthermore, a transformer core is fixedly installed inside the magnetic interference protection housing, and the grounding pin is fixedly connected to the iron core of the transformer core.

[0012] Furthermore, an outlet terminal is fixedly mounted on the top of the magnetic interference protection housing, heat dissipation fins are fixedly mounted on both sides of the magnetic interference protection housing, and a heat dissipation fan is fixedly mounted on one side of the heat dissipation fins.

[0013] Furthermore, a mounting base is fixedly installed on the top of the anti-magnetic interference shell, an oil pillow is fixedly installed on the top of the mounting base, a supporting rib is fixedly installed on the bottom of the oil pillow, one side of the supporting rib is fixedly connected to one side of the anti-magnetic interference shell, and an exhaust pipe is fixedly installed on the bottom of the oil pillow.

[0014] Compared with the prior art, the present invention provides a magnetic interference-proof transformer with the following beneficial effects:

[0015] The magnetic interference-proof transformer is provided with a wiring internal thread cap at the bottom of a mounting base plate, connecting studs at both ends of a conductor, and threadedly connected to the wiring internal thread cap via the connecting studs. After a grounding rod is inserted into the ground, the connecting studs are threadedly connected to the grounding internal thread cap at the top of the grounding rod, thereby quickly grounding the magnetic interference-proof housing and the iron core of the transformer inner core. This solves the problem that the grounding wire of a common magnetic interference-proof transformer needs to undergo wire stripping and wiring procedures when connecting the grounding wire, which is relatively cumbersome, especially when some transformers are installed at high places and need to be operated at high altitude.
