A voltage transformer with a high-strength protective housing

Abstract

This invention provides a voltage transformer with a high-strength protective shell, relating to the field of inductor technology. It includes: a mounting section; an inner housing within the mounting section; an outer connection section above the mounting section; and an inner protective section within the mounting section. A rotating inner shell is rotatably connected to the inner cavity of the mounting shell, forming a double protective structure. Simultaneously, the aligned heat dissipation holes on the outer wall of the rotating inner shell and the external venting holes on the outer wall of the mounting shell can be switched between misalignment and alignment. In non-heat dissipation mode, the misalignment further enhances the internal sealing and protection performance, preventing corrosion of internal components by harsh external environments. This solves the problem that some existing voltage transformer shells have a single protective structure, which cannot effectively resist mechanical impacts or meet the heat dissipation requirements of the equipment, resulting in internal heat not being dissipated in time and the accumulated heat accelerating the aging of internal components.

Description

Technical Field

[0001] This invention relates to the field of inductor technology, and in particular to a voltage transformer with a high-strength protective housing. Background Technology

[0002] Voltage transformers are indispensable electrical devices in power systems. They are primarily used to convert high voltage in high-voltage systems to standard low voltage at a fixed transformation ratio, providing accurate voltage signals for power metering and relay protection devices. Simultaneously, they achieve electrical isolation between high-voltage and low-voltage circuits, ensuring the safe and stable operation of the power system and the personal safety of maintenance personnel. Voltage transformers integrate core electrical components such as inductors. As key components for voltage transformation, signal coupling, and error compensation, the inductor's operational stability directly affects the metering accuracy and reliability of the voltage transformer. Their applications are widespread, covering substations, transmission lines, industrial plants, and outdoor power distribution equipment. Some scenarios require long-term exposure to complex and harsh environments or exposure to risks such as mechanical shock and external collisions. Therefore, the housing, as a crucial protective component of the voltage transformer, directly determines the operational reliability and service life of the equipment. Currently, the housings of existing voltage transformers are mostly made of ordinary metal sheets, epoxy resin casting, or ordinary plastic materials. When used outdoors or in industrial settings, ordinary enclosures are susceptible to environmental factors such as wind, sun, rain, snow, and alternating high and low temperatures, which can lead to aging, cracking, and corrosion. This not only affects the appearance of the equipment but also damages the insulation performance of the enclosure. To facilitate the normal use of voltage transformers, a voltage transformer is needed.

[0003] Currently, the protective structure of the casing of some traditional voltage transformers is simple, which cannot effectively resist mechanical shock and environmental corrosion, nor can it meet the heat dissipation requirements of the equipment. As a result, during long-term high-load operation, the internal heat cannot be dissipated in time, and the accumulated heat will accelerate the aging of internal components. Summary of the Invention

[0004] This invention relates to a voltage transformer with a high-strength protective shell, comprising a mounting section and an internal protective section. A rotating inner shell is rotatably connected to the built-in cavity of the mounting shell, forming a double protective structure. Simultaneously, the aligned heat dissipation holes on the outer wall of the rotating inner shell and the external venting holes on the outer wall of the mounting shell can be switched between misalignment and alignment. In the non-heat dissipation state, the misalignment further enhances the internal sealing and protection performance, preventing corrosion of internal components by harsh external environments. A locking block slidably connected within the telescopic slot can be inserted into the locking slot of the rotating inner shell under the control of a telescopic cylinder, achieving a secure lock on the rotating inner shell and preventing accidental rotation of the rotating inner shell due to vibration or external forces during equipment operation, thus ensuring the stability of the protective structure.

[0008] Preferably, the telescopic cylinder is fixedly connected to the mounting platform of the mounting housing, and the telescopic cylinder is electrically connected to an external control component; a buffer spring is fixedly connected to the locking block.

[0014] The voltage transformer with a high-strength protective shell provided by the present invention has the following beneficial effects: The rotating inner shell of this invention is rotatably connected to the built-in cavity of the mounting outer shell, forming a double protection structure that can effectively isolate external dust, moisture, debris, etc. from entering the transformer. At the same time, the aligned heat dissipation holes on the outer wall of the rotating inner shell and the external venting holes on the outer wall of the mounting outer shell can be switched between misalignment and alignment. In the non-heat dissipation state, the two are misaligned, which can further improve the internal sealing and protection performance, prevent the harsh external environment from corroding the internal components, and ensure the normal operation of the equipment in complex environments.

[0015] In addition, the locking block, which is slidably connected in the telescopic slot, can be inserted into the locking slot of the rotating inner shell under the control of the telescopic cylinder, so as to securely lock the rotating inner shell and prevent the rotating inner shell from rotating accidentally due to vibration or external force during equipment operation, thus ensuring the stability of the protective structure. At the same time, the buffer spring fixed on the locking block can play a buffering role during the extension and retraction of the locking block, preventing the locking block from rigidly colliding with the locking slot, reducing component wear, and extending the service life of the locking structure.

[0016] In addition, the bottom of the mounting housing is provided with locking screw holes, and the mounting base of the internal part is connected to the locking screw holes by threaded connection. Compared with traditional fixing methods such as welding and snap-fit, the connection is not only firm, but also easy to disassemble and assemble, which greatly improves the installation efficiency of the current transformer. At the same time, the four circumferentially distributed external fixing blocks fixed to the outer wall of the mounting housing can stably fix the entire current transformer in the designated installation position, ensuring the overall operational stability.

[0017] In addition, the internal sensor fixed to the top of the support platform is electrically connected to the external control component, which can detect the internal operating status of the current transformer (especially the temperature status) in real time and transmit the detection signal to the external control component in a timely manner. When the internal temperature is too high, the control component can automatically control the telescopic cylinder and control the motor to realize the automatic adjustment of the heat dissipation structure, ensuring that the internal temperature of the current transformer is always within a reasonable range, preventing the parameters of core components such as internal inductors and intermediate terminals from deviating and insulation from aging due to high temperature, and ensuring the operating accuracy and long-term stability of the equipment.
