Description

Technical Field

[0001] This utility model relates to the field of dry-type transformer technology, and in particular to an impact-resistant dry-type transformer. Background Technology

[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, a dry-type transformer is a transformer whose core and windings are not immersed in insulating oil.

[0003] Existing technologies, such as the utility model with publication number CN205621560U, disclose a dry-type transformer, including a base for mounting a lower clamp, a set of windings mounted on the lower clamp, a longitudinal ventilation channel between the iron core and coil of the windings, a mesh heating ring connected in the middle of the longitudinal ventilation channel, a first temperature sensor and a first humidity sensor located in the longitudinal ventilation channel below the mesh heating ring, and a second temperature sensor and a second humidity sensor located above the mesh heating ring; a fan connected to the longitudinal ventilation channel via an air outlet pipe is provided on the lower side of each winding, and a controller is installed on the base to control the corresponding first temperature sensor, second temperature sensor, first humidity sensor, second humidity sensor, mesh heating ring, and fan. The advantages of this utility model are: the fan circulates cold and hot air according to the temperature and humidity inside the windings, which prevents unnecessary damage to the insulation material caused by electrical conduction inside the transformer, improves the load capacity, extends the transformer life, and solves the problem that moisture easily leads to low insulation resistance, mainly manifested in the iron core and high and low voltage coils.

[0004] In daily work, it has been found that dry-type transformers are very susceptible to impacts from foreign objects during use, and have poor impact resistance. Especially during the hoisting and installation phase, due to the complex operating environment and relatively limited space, the transformer is very likely to collide with surrounding objects. Once impacted, the transformer's outer shell and internal structure may be deformed, and it may also damage key components such as the internal iron core and windings, causing the transformer to deform and be damaged, thus affecting its service life. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies in terms of impact resistance by proposing an impact-resistant dry-type transformer.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an impact-resistant dry-type transformer, comprising a base and a protective device. The transformer body is disposed on the surface of the base, and the protective device is disposed on the surface of the base. The protective device includes two mounting plates, which are respectively fixedly connected to the two side surfaces of the base. A slider one and a slider two are slidably connected to the inner walls of the two mounting plates. Protective component one and protective component two are respectively inserted into the inner walls of slider one and slider two. Mounting parts are disposed on the surfaces of protective component one and protective component two, and are mounted on slider one and slider two through the mounting parts. A side protection component and an upper protection component are disposed between protective component one and protective component two. A buffer component is fixedly connected to the surface of the mounting plate, and a buffer plate is fixedly connected to the lower surface of the two mounting plates. Through the above components, protective component one and protective component two can be respectively mounted on slider one and slider two through the mounting parts. Subsequently, protective component one and protective component two, together with the side protection component, the upper protection component, and the buffer component, can play a protective role and improve the overall impact resistance.

[0009] Preferably, the mounting part includes two positioning rings fixed on the surfaces of protective component one and protective component two. The surfaces of protective component one and protective component two are each provided with threaded grooves, and nuts are threaded onto the threaded grooves. Through the above-mentioned components, after protective component one and protective component two are respectively inserted into slider one and slider two, the positioning rings contact and position with slider one and slider two. Then, the nuts installed on protective component one and protective component two are rotated so that the nuts cooperate with the positioning rings to install protective component one and protective component two on slider one and slider two.

[0010] Preferably, the buffer assembly includes a sliding sleeve fixed to the surface of the mounting plate. Two damping blocks are fixedly connected to the inner wall of the sliding sleeve, and two push rods are slidably connected to the inner wall of the sliding sleeve. Through the above components, when the first and second protective components are impacted, the first and second sliding blocks move in the inner wall of the mounting plate, and then push the push rods. The push rods press against the damping blocks to achieve the function of buffer protection.

[0011] Preferably, a spring is sleeved on the surface of the push rod, and the two ends of the spring are fixedly connected to the surfaces of the push rod and the sliding sleeve, respectively. Through the above components, the spring can work with the damping block to buffer the impact, and at the same time, it can drive the push rod to reset.

[0012] Preferably, the first protective component and the second protective component are composed of a U-shaped frame and multiple crossbars in the U-shaped frame.

[0026] In this embodiment, protective component 1 35 and protective component 2 36 can be installed on slider 1 33 and slider 2 34 respectively by mounting part 39.
