Description

Technical Field

[0001] This utility model relates to the field of power equipment accessories technology, and in particular to a mounting base for a single-phase pad transformer. Background Technology

[0002] With the rapid development of my country's national economy, the demand for electricity is also increasing. As the main equipment in the power transmission and transformation system, transformers have also developed rapidly. A transformer is a device that uses the principle of electromagnetic induction to convert a voltage and current of one level into a voltage and current of another level at the same frequency between two or more coils and transmit electrical energy. There are various types of transformers, including single-phase transformers, which are transformers in which both the primary winding and the secondary winding are single-phase windings.

[0003] Chinese patent document CN201720006094.2 discloses a resin-insulated dry-type transformer base. This resin-insulated dry-type transformer includes three windings mounted on the base. The base includes a first and second channel steel arranged in parallel, extending along a first direction with their openings facing downwards. The base also includes a third and fourth channel steel arranged in parallel, extending along a second direction and fixed above the first and second channel steels. The openings of the third and fourth channel steels face upwards, and a fan is disposed within the U-shaped space formed by their upward-facing openings. The first direction is perpendicular to the second direction. This novel base, constructed of channel steel, provides high support strength and is less prone to wobbling with the ground. The upward-facing openings of the third and fourth channel steels can be used to limit the movement of the fan.

[0004] However, the above-mentioned patent has certain drawbacks in its use. The specifications of utility poles vary from country to country, and the mounting bracket can only be used for installation on utility poles in a single scenario. When the transformer is installed on utility poles of different national specifications, the mounting bracket needs to be redesigned to adapt to the specific requirements, thus limiting its applicability.

[0005] To address this issue, a mounting bracket for single-phase pad transformers is proposed. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, this utility model provides a mounting base for a single-phase pad transformer.

[0007] This utility model is achieved using the following technical solution:

[0008] A mounting base for a single-phase pad transformer includes a support beam made of channel steel. The support beam is provided in two sets, which are arranged in parallel. Each set contains two support beams, and an adjusting beam is provided between each set of support beams. The adjusting beam is made of rectangular steel, and the support beams are symmetrically inserted on both sides of the adjusting beam.

[0009] The end of the support beam is provided with an adjustment hole that passes through the support beam. The adjustment beam is provided with multiple adjustment holes, and a connecting bolt is provided in the adjustment hole. The connecting bolt fixes the adjustment beam and the support beam together.

[0010] The lower end of the support beam is also provided with a clamping device, which is used to fix the support beam to the utility pole.

[0011] The clamping device is provided in two sets, symmetrically fixed at the lower end of the support beam. The clamping device includes a clamp, and there are two clamps. The clamp is a semi-circular steel bar. The two ends of the clamp are provided with ear plates. The ear plates are integrated with the clamp. The ear plates are provided with through holes. The clamps are fixedly connected to each other by bolt fasteners.

[0012] A connecting plate is provided on the side wall at the top of the ear plate. The connecting plate has through holes. The connecting plate is welded and fixed to the ear plate. The connecting plate is fixedly connected to the support beam by bolts and fasteners.

[0013] The inner wall of the clamp is provided with a limiting plate, there are two limiting plates, and a clamping block is provided between the limiting plates. The clamping block is bonded to the clamp, and the upper end of the clamping block is thin and the lower end is thick.

[0014] Multiple connecting rods are provided between the support beams. The support beams are provided with waist-shaped grooves. The two ends of the connecting rods are provided with limiting plates. The outer walls of the two ends of the connecting rods are provided with threads. The limiting plates abut against the back of the support beams. The two ends of the connecting rods pass through the waist-shaped grooves and are fixedly connected to the support beams by nuts.

[0015] A terminal block is provided at the lower end of one side of the support beam. The terminal block has threads on its outer wall and a ground wire is fitted onto it. The ground wire is fixed to the terminal block by a nut.

[0016] The present invention has the following advantages over the prior art:

[0017] 1. By setting an adjusting beam between the support beams, and setting adjusting holes on the adjusting beam and the support beam, the adjusting holes allow connecting bolts to pass through, fixing the support beam and the adjusting beam together. At the same time, by selecting different positions of the adjusting holes, the spacing between the support beams can be adjusted. The setting of adjusting holes and connecting bolts allows for convenient adjustment of the spacing between the support beams to adapt to transformers of different sizes and utility poles of different spacing, thus increasing the applicability of the device.

[0018] 2. By installing a clamping device at the lower end of the support beam, the clamping device contains a semi-circular steel bar that is fixed together with bolts to form a complete circular structure that tightly holds the utility pole. By adjusting the tightness of the bolts, it can accommodate utility poles of different diameters, improving the applicability of the mounting base. The clamping device ensures that the mounting base can be firmly fixed to the utility pole, improving the stability of the mounting base. Attached Figure Description
