Abstract
Description
Technical Field
[0001] This utility model relates to the field of power transformer technology, and in particular to a power transformer support foot. Background Technology
[0002] A power transformer is an electrostatic device used to convert a certain value of AC voltage into one or more other voltages with the same frequency. It is one of the main pieces of equipment in power plants and substations. However, power transformers are usually large in size and weight. In order to prevent the transformer from tipping over or shifting during installation and operation, power transformers are equipped with support feet to stably support the transformer on the ground or other mounting foundations.
[0003] However, the existing transformer support feet do not have a good connection during installation, making the installation of the support feet inconvenient; in addition, after the support feet are installed, they are not able to distribute the pressure of the transformer, resulting in local stress concentration in the transformer, which can easily cause damage. Utility Model Content
[0004] The main purpose of this utility model is to provide a power transformer support foot, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A power transformer support foot includes a power transformer. A mounting base is fixedly installed on the lower left and lower right parts of the power transformer. A first support foot is fixedly installed through the front part of the lower end of each of the two mounting bases. A third support foot is fixedly installed through the middle part of the lower end of each of the two mounting bases. A second support foot is fixedly installed through the rear part of the upper end of each of the two mounting bases.
[0007] Preferably, each of the two mounting bases has two fixing screws installed at the front and rear of its upper end, and each of the two mounting bases has a mating groove at its lower end. Through the mating groove at the lower end of the mounting base, the mounting base can be inserted precisely into the first support groove on the first support leg and the second support leg.
[0008] Preferably, both the first and second support legs have two screw holes at the middle of their upper ends, two support grooves at their upper ends, two mounting holes at the left and right sides of their upper ends, and three fixing grooves at one end of each support leg. A rubber pad is fixedly installed at the lower end of each support leg. The mounting base is secured and limited by the support grooves, and then the fixing screws are screwed into the screw holes. This not only facilitates quick connection and installation of the support legs but also prevents the mounting base from wobbling on the support legs.
[0009] Preferably, the upper end of the third support leg has two second support grooves, the front end of the third support leg is fixedly fitted with three connecting posts, and the lower end of the third support leg is fixedly fitted with a second rubber pad. The third support leg is fixedly installed between the first and second support legs via the three connecting posts. This multiple support leg design not only distributes pressure and avoids damage caused by localized stress concentration, but also, with the three connecting posts interlaced and fixedly installed between the first, second, and third support legs, further connects the three support legs. Additionally, the rubber pads at the lower ends of all three support legs improve their stability.
[0010] Preferably, the screw hole and the fixing screw are the same size and the positions are corresponding vertically.
[0011] Preferably, the mounting base is U-shaped.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. The mounting base can be inserted into the first support slot on the first and second support feet through the docking slot at the bottom of the mounting base. The first support slot clamps and limits the mounting base. Then, the fixing screw is screwed into the screw hole. This not only facilitates the quick docking and installation of the support feet, but also prevents the mounting base from shaking on the support feet.
[0014] 2. After the first and second support legs are installed, the third support leg, which is between the first and second support legs, is also snapped into the lower middle part of the mounting base. The design of multiple support legs can not only distribute the pressure and avoid damage caused by local stress concentration, but also has three connecting columns interspersed and fixed between the first, second and third support legs to further connect the three support legs. In addition, rubber pads are set at the lower end of the three support legs to improve the stability of the support legs. Attached Figure Description

[0023] like Figures 1-4 As shown, a power transformer support foot includes a power transformer 1. Mounting bases 2 are fixedly installed on the lower left and lower right parts of the power transformer 1. A first support foot 3 is fixedly installed through the lower front part of each of the two mounting bases 2. A third support foot 5 is fixedly installed through the lower middle part of each of the two mounting bases 2. A second support foot 4 is fixedly installed through the upper rear part of each of the two mounting bases 2.
[0024] Two fixing screws 20 are installed at the front and rear of the upper end of each of the two mounting bases 2, and a mating groove 21 is opened at the lower end of each of the two mounting bases 2; the mounting base 2 is U-shaped. The transformer model is S11-10KV transformer. Through the mating groove 21 opened at the lower end of the mounting base 2, the mounting base 2 can be inserted into the first support groove 30 on the first support foot 3 and the second support foot 4.
[0025] Both support legs 3 and 4 have two screw holes 31 at their upper center, two support grooves 30 at their upper ends, and two mounting holes 32 on their upper left and upper right sides. Each support leg 3 and 4 has three fixing grooves 33 at one corresponding end. A rubber pad 34 is fixedly installed at the lower end of both support legs 3 and 4. The screw holes 31 are the same size as the fixing screws 20 and are vertically aligned. The mounting base 2 is secured and limited by the support grooves 30. Then, the fixing screws 20 are screwed into the screw holes 31. This not only facilitates quick connection and installation of the support legs but also prevents the mounting base 2 from wobbling on the support legs.
[0026] The upper end of support leg 5 has two support grooves 40. Three connecting posts 41 are fixedly installed at the front end of support leg 5, and a rubber pad 42 is fixedly installed at the lower end. Support leg 5 is fixedly installed between support leg 3 and support leg 4 via the three connecting posts 41. This multiple support leg design not only distributes pressure and avoids damage caused by localized stress concentration, but also connects support legs 3, 4, and 5 with three connecting posts 41. Furthermore, rubber pads at the lower ends of all three support legs enhance their stability.
[0027] It should be noted that this utility model is a power transformer support foot. Through the docking groove 21 opened at the lower end of the mounting base 2, the mounting base 2 can be inserted into the first support groove 30 on the first support foot 3 and the second support foot 4. The first support groove 30 clamps and limits the mounting base 2. At this time, the fixing screw 20 is screwed into the screw hole 31. This not only facilitates the quick docking and installation of the support foot, but also prevents the mounting base 2 from shaking on the support foot. After the first support foot 3 and the second support foot 4 are installed, the third support foot 5 between the first support foot 3 and the second support foot 4 is also clamped in the middle of the lower end of the mounting base 2. The design of multiple support feet can not only distribute the pressure and avoid damage caused by local stress concentration, but also three connecting posts 41 are inserted and fixed between the first support foot 3, the second support foot 4 and the third support foot 5 to further connect the three support feet. In addition, rubber pads are provided at the lower end of the three support feet to improve the stability of the support feet.
