Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of current transformer coils, and particularly relates to a fixture structure for current transformer coils. Background Technique
[0002] The fixture structure of the current transformer coil is a commonly used structure in the technical field of current transformer coils. In the circuits of power generation, transformation, transmission, distribution, and power consumption, the current magnitudes vary greatly, ranging from a few amperes to tens of thousands of amperes. For the convenience of measurement, protection, and control, it is necessary to convert to a relatively unified current. In addition, the voltage on the line is generally relatively high, and it is very dangerous to measure directly. The current transformer plays the role of current transformation and electrical isolation.
[0003] However, the fixture structures of general current transformer coils cannot clamp current transformer coils of different specifications. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a fixture structure for current transformer coils, which solves the problem that the fixture structures of general current transformer coils cannot clamp current transformer coils of different specifications.
[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:
[0006] The utility model is a fixture structure for current transformer coils, including a bottom plate and a fixture assembly. The fixture assembly includes a support plate. There are two groups of the support plates. One group of the support plates is fixedly connected to one side of the upper surface of the bottom plate. A chute is opened on the other side of the upper surface of the bottom plate. The bottom of the other group of support plates is fixedly connected with a slider. The slider is arranged in the chute and is slidably matched with it. One side surface of each of the two groups of support plates is fixedly connected with a mounting frame. An electric push rod is installed inside the mounting frame. The output end of the electric push rod is fixedly connected with a sliding rod. The sliding rod is arranged inside the support plate and is slidably matched with it.
[0007] One end of the sliding rod is fixedly connected with a fixed block. The fixed block is arranged outside the support plate. Linkage rods are hinged at both ends of the fixed block. One end of the linkage rod is hinged with a connecting rod. One end of the connecting rod is hinged with a clamping plate. The clamping plate is arranged above the bottom plate. A clamping roller is rotatably connected inside the clamping plate.
[0008] Fixed plates are fixedly connected to both side surfaces of the support plate. A cross plate is fixedly connected to one end of the fixed plate. A linkage block is hinged to one side inside the clamping plate. One end of the linkage block and one side inside the connecting rod are both fixedly connected with a connecting rod. One ends of the two groups of connecting rods are respectively hinged to both ends of the cross plate.
[0009] A threaded rod is rotatably connected inside the sliding groove. The slider is arranged on the periphery of the threaded rod and is in threaded cooperation with it. One end of the threaded rod is fixedly connected with a handle, and the handle is arranged outside the bottom plate. By providing the sliding groove and the threaded rod, the distance between the two support plates can be adjusted, and the clamping of current transformer coils of different specifications can be realized by using the clamping plate and the clamping roller.
[0010] The clamping roller is made of rubber.
[0011] The utility model has the following beneficial effects:
[0012] In the utility model, by providing a fixture assembly and an electric push rod, when the electric push rod is started, it drives the sliding rod to slide inside the support plate, and then drives the fixed block to move, so that the linkage rod drives the connecting rod to swing. Then, with the cooperation of the cross plate, the linkage block and the connecting rod, the clamping plate is driven to swing. Then, through the contact between the clamping roller and the current transformer coil, the clamping of the current transformer coil is realized, making the clamping force on the current transformer coil uniform and avoiding damage. In addition, by providing the sliding groove and the threaded rod, the distance between the two support plates can be adjusted, and the clamping of current transformer coils of different specifications can be realized by using the clamping plate and the clamping roller.
[0013] Of course, when implementing any product of the utility model, it is not necessarily required to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
