Description

Technical Field

[0001] This utility model relates to the field of metering voltage transformer technology, specifically a metering voltage transformer connector. Background Technology

[0002] A metering voltage transformer is a voltage transformer specifically designed to provide voltage to electricity meters and other similar devices; it is a key component of a metering unit. Its main function is to convert high voltage to low voltage for use by measuring instruments and protection equipment.

[0003] A metering voltage transformer is similar to a transformer, but its main purpose is to convert high voltage to low voltage so that measuring instruments and protection devices can operate safely and reliably. This conversion enables measuring instruments and relay protection devices to operate normally in high-voltage environments, thereby achieving accurate measurement of line voltage, power, and electrical energy, and protecting valuable equipment in the event of a fault.

[0004] For example, utility model application No. 202322641223.3 discloses a metering voltage transformer connector. This connector fixes the base plate at the target position, then inserts the snap-fit ​​bracket into the connector, uses a first positioning mechanism for initial positioning, and finally uses a baffle and a second positioning mechanism for secondary positioning. This achieves good installation effect on the transformer body, requires no additional tools during installation, is not easy to loosen after installation, has good stability, and is easy to disassemble and assemble when maintenance is required, making the maintenance process time-saving and labor-saving, thus meeting the usage requirements. However, connectors similar to those in the above-mentioned document have relatively complicated structural combinations, requiring certain combinations and connections, which limits their convenience. At the same time, they cannot provide good structural protection for the transformer body, making the transformer body prone to structural damage.

[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a metering voltage transformer connection base. Utility Model Content

[0006] The purpose of this utility model is to provide a metering voltage transformer connector to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a metering voltage transformer connector, comprising a transformer assembly and a connector component. The connector component is installed at the bottom of the transformer assembly, and a protective frame component is provided around the transformer assembly. A protective top plate is provided on the top of the transformer assembly, and a fixing bolt is installed between the connector component and the transformer assembly. Supporting screws are vertically inserted through the four opposite corners of the protective frame component, and a limit nut is provided between the protective frame component and the protective top plate. A fastening bolt is installed at the connection between the protective top plate and the supporting screws.

[0008] Furthermore, the transformer assembly includes a voltage transformer body, a base plate, support piles, and connecting piles. The bottom of the voltage transformer body is connected to the base plate, and the center of the bottom of the base plate is connected to the support pile. Connecting piles are provided at the four opposite corners of the base plate.

[0009] Furthermore, the base plate, support piles, and connecting piles are integrated into a single structure, and the fixing bolts are vertically threaded through the middle of the connecting piles.

[0010] Furthermore, the connecting seat component includes a base, fixed angle plates, and connecting piles. Fixed angle plates are connected to both the left and right sides of the base, and connecting piles are symmetrically arranged on the top surface of the base.

[0011] Furthermore, the top surface of the base is provided with insertion holes that match the surface structure of the support pile and the connecting pile, and the fixing bolt and the base are connected by threads.

[0012] Furthermore, the protective frame component includes a stabilizing frame, damping sleeves, and buffer plates. Damping sleeves are provided at each of the four diagonal corners of the stabilizing frame, and buffer plates are attached to both the inner and outer sides of the stabilizing frame.

[0013] Furthermore, the lower end of the support screw is threadedly connected to the docking pile, and the support screw vertically penetrates the interior of the damping sleeve, and the limiting nut and the upper surface of the support screw are threadedly connected.

[0014] Furthermore, the upper end of the support screw is inserted into the bottom of the four opposite corners of the protective top plate, and the fastening bolt is vertically threaded to the opposite corners of the protective top plate and the inside of the upper end of the support screw.

[0015] This utility model provides a metering voltage transformer connection base, which has the following advantages:

[0016] 1. This utility model features support piles and connecting piles at the bottom of a base plate, with matching insertion holes on the top surface of the base. This allows for the quick assembly of the current transformer assembly and connecting seat components via a plug-in structure. Four sets of fixing bolts are then screwed vertically from bottom to top into the connecting piles and base, thus connecting and fixing the current transformer assembly and connecting seat components. This structure facilitates convenient assembly, improving operator efficiency and ensuring stability and robustness after assembly. Furthermore, the design simplifies the structure, optimizing production costs and providing convenient maintenance, thereby promoting its widespread use.

[0017] 2. This utility model comprises a protective frame component, a protective top plate, and supporting screws. Four sets of supporting screws are screwed into the interior of the connecting pile. The protective frame component is then fitted onto the surface of the supporting screws using a damping sleeve. The protective top plate is then inserted into the top of the supporting screws. Finally, fastening bolts are used to connect and fix the protective top plate and supporting screws, forming a frame structure. The use of limiting nuts secures the supporting screws and protective frame component, preventing unnecessary shaking or displacement. This structure ensures the stability of the structural assembly, provides excellent structural protection for the internal transformer components, ensures their normal and stable operation, reduces structural damage caused by external factors, and extends the overall service life of the structure.

The support pile 103 and the connecting pile 104 and the base 201 can be quickly combined by inserting the current transformer assembly 1 and the connecting seat component 2 through the insertion structure. Then, four sets of fixing bolts 5 are screwed into the connecting pile 104 and the base 201 from bottom to top in the vertical direction, thereby connecting and fixing the current transformer assembly 1 and the connecting seat component 2.

[0025] like Figures 1 to 4As shown, the protective frame component 3 includes a stabilizing frame 301, a damping sleeve 302, and a buffer plate 303.
