As a key device for power regulation, the performance of the magnetic pressure regulator directly affects the operation quality of the entire power system. The iron core, as the core component of the magnetic pressure regulator, its operating state plays a decisive role in the performance of the pressure regulator. In practical application, due to the complex and changeable working environment, the iron core will be affected by alternating electromagnetic force, temperature change, mechanical vibration and other factors, and is prone to looseness, displacement and other problems, resulting in unstable output voltage of the pressure regulator, and even causing equipment failure. Therefore, it is an urgent need to develop an efficient and reliable iron core clamping device to improve the performance of the magnetic pressure regulator.

[0003] Traditional iron core clamping devices mostly adopt mechanical clamping methods, such as bolt fastening, plate pressing, etc. These methods are prone to cause clamping force to decrease due to vibration, thermal expansion and contraction, etc. during long-term operation, resulting in looseness of the iron core. When the iron core is loose, the air gap of the magnetic circuit will change, affecting the electromagnetic performance of the pressure regulator and reducing the operating efficiency of the equipment.

[0004] Different types of magnetic pressure regulators have different sizes, shapes and structures of the iron core. Traditional clamping devices are often designed for specific models of iron core, with poor universality. In the production and maintenance process, different clamping devices need to be provided for different models of pressure regulators, increasing the production cost and maintenance difficulty.

[0005] Therefore, the utility model provides a magnetic pressure regulator iron core clamping device. UTILITY MODEL CONTENTS
