Description

Technical Field

[0001] This utility model relates to the field of current transformer technology, specifically a through-type current transformer. Background Technology

[0002] A current transformer is an instrument that converts a large primary current into a small secondary current based on the principle of electromagnetic induction for measurement or protection. A through-type current transformer is a special type of current transformer designed to pass through panels or walls and can be installed in holes in walls or metal structures.

[0003] When installing a through-type current transformer, bolts are usually used to fix it through the bolt holes of its bracket. Since the through-type current transformer will vibrate during operation, the bolts are at risk of loosening due to vibration, and there is a lack of shock absorption structure. Therefore, a through-type current transformer is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a through-type current transformer to solve the problem that the bolts may loosen if the current transformer vibrates during operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A through-type current transformer includes a current transformer body for converting a large current into a small current and a bracket for fixing the current transformer body. A rod-shaped bracket is fixedly connected to the outside of the current transformer body. A shock-absorbing assembly is provided at the bottom of the bracket. The shock-absorbing assembly includes a fixing plate, a rubber layer, a damping rod, and a damping spring. The fixing plate is covered with a rubber layer, and a damping rod is fixedly connected to the bottom of the rubber layer. A damping spring is provided on the outside of the damping rod. A mounting assembly is provided at the bottom of the damping rod, including a mounting base and bolts. The mounting base is fixedly connected to the bottom of the damping rod, and a bolt is provided on one side of the mounting base.

[0007] Preferably, several damping rods and shock-absorbing springs are arranged as a group between the rubber layer and the mounting base, and one side of the rubber layer is fixedly connected to the bracket.

[0008] Preferably, a heat dissipation assembly is provided on the left side of the current transformer body, the heat dissipation assembly including a heat-conducting rod and a support plate.

[0009] Preferably, a support plate is fixedly connected to the left side of both the bracket and the current transformer body, and a heat-conducting rod passes through the support plate.

[0010] Preferably, the heat-conducting rods are arranged in groups of several and the bends are arc-shaped. One end of the heat-conducting rod is located in the recess on the left side of the current transformer body, and the other end of the heat-conducting rod is located above the mounting base.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the current transformer body, bracket, shock-absorbing components, fixing plate, rubber layer, damping rod, and shock-absorbing spring are designed to absorb and buffer vibrations generated during operation. The damping rod and spring work together to provide overall shock absorption and buffering above the mounting base, preventing the risk of bolts loosening due to vibration. The mounting components, mounting base, and bolts facilitate the installation of the current transformer body. The heat dissipation components, heat-conducting rod, and support plate allow heat inside the current transformer body to be transferred to the outside via the heat-conducting rod. Compared to natural ventilation heat dissipation in the prior art, this increases the speed of heat dissipation, thereby improving the heat dissipation effect. The shock-absorbing components between the current transformer body and the mounting base provide shock absorption and buffering after installation, preventing the risk of bolts loosening due to vibration during operation. The heat dissipation components improve the overall heat dissipation effect of the current transformer body. Attached Figure Description

[0020] Please see Figure 1-3 This utility model provides a technical solution:

[0021] A through-type current transformer includes a current transformer body 1 for converting a large current into a small current and a bracket 2 for fixing the current transformer body 1. The bracket 2, which is rod-shaped, is fixedly connected to the outside of the current transformer body 1. A shock-absorbing assembly 3 is provided at the bottom of the bracket 2. The shock-absorbing assembly 3 includes a fixing plate 31, a rubber layer 32, a damping rod 33, and a shock-absorbing spring 34. The fixing plate 31 is located at the bottom of the bracket 2, and the outside of the fixing plate 31 is covered with a rubber layer 32. The bottom of the rubber layer 32 is fixedly connected to the damping rod 33. A shock-absorbing spring 34 is provided on the outside, and a mounting component 4 is provided at the bottom of the damping rod 33. The mounting component 4 includes a mounting base 41 and a bolt 42. The mounting base 41 is fixedly connected to the bottom of the damping rod 33, and a bolt 42 is provided on one side of the mounting base 41. By setting the shock-absorbing component 3 between the current transformer body 1 and the mounting base 41, it has a shock-absorbing and buffering effect after installation, avoiding the risk of the bolt 42 loosening when vibration occurs during operation. The heat dissipation component 5 improves the overall heat dissipation effect of the current transformer body 1.

[0022] Several damping rods 33 and shock-absorbing springs 34 are arranged in a group between the rubber layer 32 and the mounting base 41. One side of the rubber layer 32 is fixedly connected to the bracket 2, so that the current transformer body 1 has a shock-absorbing and buffering effect. A heat dissipation component 5 is provided on the left side of the current transformer body 1. The heat dissipation component 5 includes a heat-conducting rod 51 and a support plate 52, which increases the heat dissipation effect of the current transformer body 1. The support plate 52 is fixedly connected to both the bracket 2 and the left side of the current transformer body 1. The heat-conducting rod 51 passes through the support plate 52 to fix the heat-conducting rod 51. Several heat-conducting rods 51 are arranged in a group and the bend is arc-shaped. One end of the heat-conducting rod 51 is located in the recess on the left side of the current transformer body 1, and the other end of the heat-conducting rod 51 is located above the mounting base 41 for easy use of the heat-conducting rod 51.

[0023] Working Process: When using a through-type current transformer, first place the mounting base 41 at the bottom of the current transformer body 1 in a suitable position. Then, pass the bolts 42 through the pre-drilled bolt holes in the mounting base 41 and tighten them to fix the mounting base 41. At the same time, fix the current transformer body 1. After installation, energize the current transformer body 1 to put it into working condition. When it vibrates, because the current transformer body 1 and the bracket 2 are fixedly connected, the bracket 2 and the rubber layer 32 are fixedly connected, and the rubber layer 32 has a fixing plate 31, the fixing plate 31 is driven to vibrate above the mounting base 41. Because there is a damping rod 33 and a shock-absorbing spring 34 between the mounting base 41 and the rubber layer 32, the damping rod 33 and the shock-absorbing spring... The spring 34 is used in conjunction to reduce the vibration amplitude, thereby providing a shock-absorbing and buffering effect between the current transformer body 1 and the mounting base 41. During operation, the current transformer body 1 generates heat due to the current passing through it. This internal heat can be transferred from one end of the heat-conducting rod 51 to the other end, accelerating the heat outflow and improving the heat dissipation effect. The support plate 52 effectively fixes the heat-conducting rod 51. The shock-absorbing component 3 installed between the current transformer body 1 and the mounting base 41 provides a shock-absorbing and buffering effect after installation, avoiding the risk of the bolt 42 loosening due to vibration during operation. The heat dissipation component 5 improves the overall heat dissipation effect of the current transformer body 1.
