Description
Technical Field
[0001] This utility model relates to the field of power transformer technology, specifically to a shock-resistant and protective power transformer. Background Technology
[0002] A power transformer is a static electrical device used to convert a given AC voltage (current) into one or more different voltages (currents) with the same frequency. As power transformers are essential for power transmission and distribution, they play a vital role in our production and daily lives. Traditional power transformers are often susceptible to vibration during use, leading to malfunctions. Traditional power transformers are mostly directly mounted on vibration-damping supports, and during vibration, the transformer's back-and-forth movement can cause it to collide with the protective casing, making disassembly and assembly inconvenient. Therefore, we propose a vibration-resistant and protective power transformer. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a shock-resistant and protective power transformer. The use of shock-absorbing springs and shock-absorbing pads can effectively cancel the vibration generated by the power transformer. The protective shell can also protect the power transformer without affecting heat dissipation. The internal rubber pad can prevent the power transformer from colliding with the protective shell during vibration. This can effectively solve the problems in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a seismic-resistant power transformer includes a base and a seismic-resistant unit;
[0005] Base: A fixed seat is placed on the top surface, and the inside of the fixed seat is correspondingly engaged with the base frame. The transformer body is installed on the top surface of the base frame, and a protective unit is provided on the top surface of the base.
[0006] The seismic unit includes a sliding plate, damping rods, and shock-absorbing springs. There are four damping rods, which are fixed in pairs to the left and right sides inside the base. The inner end of each pair of damping rods is fixed with a sliding plate. The sliding plate is slidably connected to the through groove on the top surface of the base. The top of the sliding plate is connected to the bottom surface of the fixed seat. Shock-absorbing springs are evenly distributed on the outer side of the sliding plate. The outer end of the shock-absorbing spring is connected to the side inside the base.
[0007] It also includes a controller, which is located on the front side of the base. The input end of the transformer body is electrically connected to the output end of the controller, and the input end of the controller is electrically connected to the output end of an external power source.
[0008] The combination of shock-absorbing springs and damping rods can effectively absorb and reduce vibrations generated by the transformer body, and at the same time reduce the impact of ground vibrations on the transformer body.
[0009] Furthermore, the seismic unit also includes a connecting plate, an adjusting plate, a locking block, and a screw. There are four connecting plates, which are fixed in pairs to the left and right sides of the fixed base. A screw is installed on the surface of the connecting plate, and the screw is threadedly connected to the screw hole on the surface of the adjusting plate. The adjusting plate is slidably installed with the adjusting groove on the side of the fixed base. A locking block is fixed to the end of the adjusting plate, and the locking block is slidably connected to the inside of the fixed base. Rotating the screw causes the locking block to engage with the inside of the base frame, which facilitates the disassembly and assembly of the transformer body.
[0010] Furthermore, the seismic unit also includes a limiting groove, a limiting block, and a shock-absorbing pad. There are two limiting grooves, each opened on the bottom surface inside the fixed seat. Limiting blocks are fixed on both the front and rear sides of the bottom surface of the shock-absorbing pad. The limiting blocks are inserted into the limiting grooves to install the shock-absorbing pad, thereby reducing the gap between the base frame and the fixed seat and thus reducing the generation of vibration.
[0011] Furthermore, the protective unit includes a transparent window, a protective shell, rubber pads, mounting blocks, and heat dissipation holes. Mounting blocks are fixed on both sides of the bottom surface of the protective shell, and the mounting blocks are inserted into the mounting grooves on the top surface of the base. A transparent window is installed on the top surface of the protective shell, and heat dissipation holes are opened on the surface of the protective shell. There are two rubber pads, which are respectively glued and fixed to the left and right sides inside the protective shell. The protective shell can protect the transformer body, and the rubber pads inside can prevent the transformer body from colliding with the protective shell during vibration. The transparent window installed on the top surface allows personnel to inspect the power transformer.
[0012] Furthermore, the protective unit also includes a socket, a rod, a spring, and a support plate. There are two springs, which are fixed to the middle of the left and right sides of the base respectively. The outer end of the spring is fixed to the support plate. The front and rear sides of the support plate are equipped with rods. The rods are slidably connected to the through holes on the side of the base. The socket is opened on the surface of the mounting block. The spring contracts and extends to make the rods and sockets correspond and cooperate, which facilitates the quick assembly and disassembly of the protective shell.
[0013] Furthermore, it also includes a wireless transmitter, which is fixed to the bottom surface inside the base. The output end of the wireless transmitter is electrically connected to the input end of the controller. The wireless transmitter can transmit the real-time operating status of the power transformer to personnel to prevent the power transformer from being affected by vibration failures and thus affecting its subsequent use.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This earthquake-resistant power transformer has the following advantages:
[0015] 1. By using shock-absorbing springs in combination with damping rods, the vibration generated by the transformer body can be effectively absorbed and reduced. At the same time, the impact of ground vibration on the transformer body can also be reduced. The limit block is inserted into the limit groove to install the shock-absorbing pad, thereby reducing the installation gap between the base frame and the fixed seat, and thus reducing the generation of vibration.
[0016] 2. The protective shell can protect the transformer body. The internal rubber pads can prevent the transformer body from colliding with the protective shell during vibration. The transparent window installed on the top surface allows personnel to inspect the power transformer.
[0017] 3. By rotating the screw, the locking block is engaged inside the base frame, which facilitates the disassembly and assembly of the transformer body. At the same time, the spring contracts and extends to make the plug rod and plug hole align, which facilitates the quick disassembly and assembly of the protective shell. Attached Figure Description
