Problems solved by technology

[0004] Most of the existing high-voltage power transformers are installed by means of flange installation or bonding. The installation position generally needs to be reserved, so the application and promotion of high-voltage power transformers are more restricted.

Embodiment 1

[0019] This embodiment is a high-voltage power transformer, see Figure 1 to Figure 7 As shown, it includes a base 1, a flat nut 2, a set of pressing claw assemblies 3, and a transformer 7; the pressing claw assembly includes three pressing claws 4; the base is provided with a sliding tube 11 and a radial guide limit set on the sliding tube Position hole 12 and a stop 13 formed on the outer peripheral wall of the slide tube and formed convexly along the radial direction of the slide tube;

[0020] The plane nut 2 is ring-shaped, and the plane nut is slidingly sleeved on the outer peripheral wall of the base sliding tube 11; the transformer is also ring-shaped, and is fixedly sleeved on the outer peripheral wall of the base sliding tube;

[0021] The shape of the stopper is ring-shaped, and the stopper is located at the middle end of the slide tube of the base;

[0022] The transformer and the plane nut are located on both sides of the stopper, and the radial guide limit hole 12 is t...

Embodiment 2

[0037] This embodiment is basically the same as embodiment 1, the difference lies in: see Figure 8 As shown, in order to be used as a splice clamp for insulated power cables, this embodiment is also provided with a plurality of piercings 42 on the inner wall of the pressure plate portion. Specifically, the punctures are provided on the inner wall of the arc groove of each pressure plate portion, each The puncture protrudes radially inward along the base sliding tube 11. The existence of puncture can effectively connect electricity without stripping the insulated power cable. In the first embodiment, since the bare wire is connected, the puncture may not be provided.

[0038] Each puncture is made during casting; in specific practice, the puncture can also be made in other ways; for example, a plurality of installation slots are provided on the inner wall of the pressure plate part, and then the puncture piece made by punching is embedded In a corresponding mounting slot, the pi...

Abstract

The invention discloses a high-voltage power transformer. The high-voltage power transformer comprises a base body, a planar nut, a press claw assembly and a mutual inductor, wherein the press claw assembly comprises three press claws, the base body is provided with a sliding tube, a baffle table and three radial guide limitation holes, the planar nut and the mutual inductor both sleeve the outer peripheral wall of the sliding tube of the base body, the planar nut is arranged between the radial guide limitation holes and the baffle table, each press claw is arranged in one corresponding radial guide limitation hole and is provided with a press plate part, a guide sliding block part and a driving threaded part, a fastening part is arranged on the outer peripheral wall of the planar nut, the planar nut is provided with planar threaded parts which are engaged with and adaptive to the driving threaded part of each press claw, each press claw is driven to get close to or depart from the center of the sliding tube when the planar nut rotates in a reciprocating way, the inner peripheral wall of the planar nut is a smooth inner wall adaptive to the outer peripheral wall of the sliding tube of the base body, one side end, adjacent to the baffle table, of the planar nut is adjacent to the baffle table in a sliding way, and an Archimedes spiral groove is formed in each planar threaded part. The high-voltage power transformer is convenient to install.

Description

Technical field [0001] The invention belongs to the technical field of high-voltage power, and specifically relates to a high-voltage power transformer. Background technique [0002] High-voltage power transformers are transformers that are suitable for converting large voltages into small voltages or large currents into small currents in 1kv to 220kv power systems to facilitate measurement, protection and use. [0003] Most of the existing high-voltage power transformers are electromagnetic induction transformers, with the same working principle as the transformer, and the basic structure is also an iron core and primary and secondary windings. The main functions of high-voltage power transformers are as follows: convert high voltage into low voltage, and large current into small current, and then used for measurement, control, and protection. In this way, not only can the measuring instrument process be increased, the instrument standardization can be facilitated, the voltage an...
