Description

Technical Field

[0001] This invention relates to the field of outdoor transformer technology, specifically to an outdoor transformer with a safety protection mechanism and its protection method. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil, and iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. An outdoor transformer is a transformer that can withstand outdoor weather conditions. When an outdoor transformer is installed and used outdoors, a safety protection mechanism must be installed to protect the transformer body.

[0003] For example, application number 202121549934.2 (titled "A Transformer with Safety Protection Function") includes: a transformer body, with an oil conservator disposed on one side of the transformer body surface; a protective component disposed on the surface of the oil conservator; and two heat dissipation components, each disposed on one side of the protective component. Each protective component includes an L-shaped sliding rod, which is fixedly installed on one side of the oil conservator surface. This invention provides a transformer with safety protection function. The L-shaped sliding rod and movable ring on the surface of the oil conservator, used in conjunction with a protective cover, facilitate operator maintenance and simplify operation. The fixing bolts on the L-shaped sliding rod help secure the movable ring and protective cover, reducing interference during operator maintenance. The rotating rod and folding plate inside the placement slot provide heat dissipation during operation.

[0004] The aforementioned safety protection mechanisms for transformers are ineffective in dealing with strong outdoor winds, making them prone to being blown away and affecting their lifespan when installed outdoors. Therefore, we provide an outdoor transformer with a safety protection mechanism and its protection method. Summary of the Invention

[0021] Preferably, the protection method for an outdoor transformer with a safety protection mechanism includes the following steps:

[0022] Step 1: Install the outer protective cylinder onto the outside of the stainless steel safety cabinet by connecting the through rod to the corresponding hole, and then install the locking nut on the threaded wall to lock and fix it in place.

[0023] Step 2: After the outer protective cylindrical sleeve is installed, the transmission shaft is inserted and positioned by the locking end block at one end into the locking groove on the connecting transmission shaft; then, two pre-embedded pits are dug in the ground, and the pre-embedded frame is pre-embedded and filled into the pre-embedded pits;

[0024] Step 3: Ground the support base by installing the end plate. The transformer wiring is routed through stainless steel embedded pipes, and the wiring path is underground.

[0025] Step 4: When strong winds occur outdoors, the downwind plate adapts to the wind direction and drives the outer protective cylinder to rotate. The outer protective cylinder rotates inside the inner groove, and during the movement, it drives the gearbox's connecting drive shaft to rotate synchronously.

[0026] Step 5: The gearbox's drive shaft rotates, and the meshing of the gears in the gearbox drives the generator's shaft to rotate, enabling the generator to generate electricity. The generated electrical energy is then processed by the rectifier and the charging controller and stored in the battery for later use.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. This invention uses a through-hole to connect the outer protective cylinder to the outside of a stainless steel safety cabinet. When strong winds occur outdoors, the windward plate adapts to the wind direction and drives the outer protective cylinder to rotate. The outer protective cylinder rotates within the inner groove, causing the gearbox's drive shaft to rotate synchronously. The rotation of the gearbox's drive shaft, through gear meshing, drives the generator's shaft to rotate, enabling the generator to generate electricity. The generated electricity is processed by a rectifier and a charging controller and stored in the battery for later use. This achieves the goal of protecting the transformer while simultaneously generating electricity in response to wind direction, overcoming the problem that existing transformer safety protection mechanisms cannot effectively cope with strong outdoor winds, leading to transformers being easily blown away.

[0029] 2. Two pre-buried pits are dug in the ground, and the pre-buried frame is pre-buried and filled into the pre-buried pits. The support base is grounded by installing the end plate. The transformer wiring is routed through stainless steel pre-buried pipes. The wiring path is underground to protect the transformer line. Attached Figure Description
