Abstract
Description
Technical Field
[0001] This application relates to the field of current transformer technology, and more specifically to a current transformer conductor assembly. Background Technology
[0002] Oil-immersed vertical current transformers, widely used in medium- and high-voltage power systems, play a crucial role in the power industry. With the continuous development and upgrading of power systems, the performance and reliability requirements for current transformers are becoming increasingly stringent. They can proportionally transform alternating current, providing accurate current signals for measurement, protection, and control devices, which is of great significance for ensuring the safe and stable operation of power systems. Their applications cover various medium- and high-voltage power scenarios, such as substations and power plants, playing a key supporting role in the development of the entire power industry.
[0003] In existing technologies, specific conductor assemblies are typically used to connect the primary winding of a current transformer to an external circuit. Generally, these conductor assemblies are U-shaped and mainly consist of conductors and terminals. The connection between the terminals and the conductor assembly is commonly achieved through welding. This method ensures a certain degree of stability and reliability in the connection and is widely used in the manufacturing of various current transformers. Through welding, the conductor assembly and terminals form a relatively robust integrated structure, which can effectively perform the tasks of current transmission and connection under normal operating conditions.
[0004] However, while welding the terminal blocks and conductor assemblies together ensures structural strength, it sacrifices installation flexibility. In special installation environments, such as those with limited space or unusual installation angles, this fixed connection method prevents the terminal blocks from being adjusted flexibly to meet actual needs, making it difficult to reliably complete wiring operations and causing numerous inconveniences in actual installation and use. Utility Model Content
[0005] In order to overcome the problem that the fixed connection method between the conductor and the terminal block in the prior art cannot adapt to complex installation conditions, this application provides a current transformer conductor assembly.
[0006] This application adopts the following technical solution: a current transformer conductor assembly, including a body and terminals. The body is U-shaped, and the lower two ends of the body are used to house the primary winding and the secondary winding. Each of the two ends of the body is provided with a terminal. The bottom of the terminal is provided with a mounting base. The terminal and the mounting base are integrally formed. The bottom of the mounting base is provided with a slot, and the end of the body can be inserted into the slot.
[0007] The width of the slot is greater than the end thickness of the body, the length of the slot is equal to the end length of the body, and an adjustment member is provided inside the slot. The thickness of the adjustment member is equal to the difference between the width of the slot and the end thickness of the body.
[0008] The mounting base, body, and adjusting component are connected by a connector.
[0009] Optionally, the connector includes a screw and a nut. The tail of the screw fits against one side of the outer wall of the mounting base and is located outside the slot. The head of the screw enters the slot from one side of the mounting base and exits the slot from the other side of the mounting base. The body and the adjusting member are both sleeved on the screw. The nut is adaptedly screwed onto the head of the screw.
[0010] Optionally, the wiring terminal is fixedly connected to the top side of the mounting base.
[0011] Optionally, the adjusting member includes at least two gaskets, and multiple gaskets are adapted to be disposed in the slot. After the body is inserted into the slot, one side of the body is in contact with the inner wall of the slot, the other side is in contact with the gasket, or both sides of the body are in contact with the gasket.
[0012] Optionally, the ends of the mounting base, gasket, and body are all provided with through holes, and the screw passes through the inner side of a plurality of the through holes.
[0013] In summary, this application includes at least one of the following beneficial technical effects:
[0014] 1. The terminal block and the mounting base are integrally formed. The bottom of the mounting base has a slot into which the end of the main body can be inserted. The mounting base, the main body and the adjusting parts are connected together by adjusting parts and connectors. This makes the terminal block and the main body no longer a fixed whole formed by welding, but can be adjusted relatively flexibly, which greatly improves the flexibility of the installation of the current transformer conductor assembly. When encountering special installation environments such as limited space or special installation angles, the wiring operation can be reliably completed.
[0015] 2. The width of the slot is greater than the thickness of the end of the body. By setting an adjusting member in the slot, the thickness of the adjusting member is equal to the difference between the width of the slot and the thickness of the end of the body. The remaining space of the slot can be reliably filled by the adjusting member, and the relative position between the terminal block and the body can be adjusted by changing the installation position of the adjusting member, thereby ensuring the stability of the connection of the current transformer conductor assembly.

[0022] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0023] like Figure 1-5 As shown, the current transformer conductor assembly includes a body 1 and a terminal block 2. The terminal block 2 is connected to the body 1 via a mounting base 3. By using different fixing methods between the mounting base 3 and the body 1, the relative position between the terminal block 2 and the body 1 can be reliably adjusted, so that the terminal block 2 can reliably complete the wiring operation even in special installation environments.
[0024] The terminal block 2 and the mounting base 3 are integrally formed. The terminal block 2 is used to connect to an external circuit. The terminal block 2 is generally flat and has mounting holes, which facilitate the connection between the terminal block and the external circuit, ensuring the connection strength and stability. The bottom of the mounting base 3 has a slot 30, into which the end of the body 1 can be inserted. The width of the slot 30 is greater than the thickness of the end of the body 1, and the length of the slot 30 is equal to the length of the end of the body 1. This allows the body 1 to be smoothly inserted into the slot 30 and maintain a close fit with the inner wall of the slot 30, while also providing space for the installation of the adjusting component 5. After the adjusting component 5 is installed, both the adjusting component 5 and the body 1 are stable within the slot 30. The adjusting component 5 includes at least two gaskets. The gaskets are usually made of insulating materials, such as plastic or rubber, to prevent safety issues such as leakage. The shape of the gaskets is adapted to the slot 30, allowing them to be tightly installed within the slot 30. After the end of the body 1 is inserted into the slot 30, one side of the body 1 can be in contact with the inner wall of the slot 30 and the other side can be in contact with the gasket; or both sides of the body 1 can be in contact with the gasket. By adjusting the number and position of the gaskets, the relative position and tightness between the body 1 and the mounting base 3 can be adjusted, thereby improving the installation flexibility of the terminal block 2 on the body 1, so that the terminal block 2 can still reliably complete the wiring operation when encountering special installation environments such as limited space or special installation angles.
[0025] The connector 4 includes a screw 41 and a nut 42. The tail of the screw 41 fits against one outer wall of the mounting base 3 and is located outside the slot 30. The head of the screw 41 enters the slot 30 from one side of the mounting base 3 and exits the slot 30 from the other side of the mounting base 3. The body 1 and the adjusting member 5 are both sleeved on the screw 41, and the nut 42 is screwed onto the head of the screw 41. By tightening the nut 42, the screw 41 is prevented from falling off, thereby ensuring that the body 1 and the adjusting member 5 are tightly connected and placed in the slot 30 of the mounting base 3. Through holes 50 are provided at the ends of the mounting base 3, the gasket, and the body 1. The screw 41 passes through the inside of these through holes 50, so that the screw 41 can reliably limit the position of the gasket and the body 1.
[0026] The implementation principle of this embodiment is as follows: By improving the connection method, the current transformer conductor assembly of this embodiment adopts an adjustable connection structure between the terminal block 2 and the body 1. Compared with the welding method used in the prior art, this greatly improves the flexibility of installation. In situations with limited space or special installation angles, the relative position between the body 1 and the terminal block 2 can be adjusted by changing the number and position of the shims. This allows the terminal block 2 to be flexibly adjusted according to actual needs, thereby reliably completing the wiring operation. This meets the usage requirements of current transformers in different installation environments in power systems, improving the practicality and reliability of the equipment.
[0027] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
