[0002] An electromagnet is a device that uses the magnetic effect of electric current to generate a magnetic field. Its core component is a solenoid with an iron core inside. When an electric current passes through the solenoid, a magnetic field will be generated around the solenoid, and the iron core will be magnetized under the action of the magnetic field, thereby greatly enhancing the magnetism of the solenoid.

[0003] The electromagnet control power supply is a special excitation power supply for inductive loads such as electromagnets and Helmholtz coils. This kind of power supply generally adopts high-performance full digital control and is a high-precision bipolar constant current power supply. The current can continuously pass through zero, and there is no contact commutation. It can generate a smooth and stable controlled magnetic field and can automatically cut off the power according to specific conditions. If the electromagnet is in a harsh environment, such as high temperature, humidity, corrosive gas, etc., more frequent maintenance may be required. However, the existing electromagnet control power supply is often fixed by bolts and is often protected by its own shell. The disassembly and assembly effect is not good. Disassembly and assembly through bolts is too cumbersome, and the protection effect of its own shell is not good enough. The problems existing in the above technology are: the disassembly and assembly method of the electromagnet control power supply is more cumbersome, and the protection effect is not good enough.

[0026] The working principle of the present utility model:

[0027] When it is necessary to remove the control power supply 1, by removing the bolts fixing the movable door 9, the movable door 9 can be rotated forward. At this time, the pull rod 702 can be pushed backward and the transmission block 701 can be moved backward. The movement of the transmission block 701 will cause the two short rods 703 to move backward. During the movement of the two short rods 703, the two movable rods 603 will be rotated, and the rear sides of the two movable rods 603 will rotate in the direction of the relative ends with the two mating blocks 604 as the centers, thereby driving the two positioning blocks 601 to move in the direction of the relative ends, so that the two positioning blocks 601 are moved out of the interiors of the two plug-in blocks 4, so that the control power supply 1 can drive the two plug-in blocks 4 to be disengaged from the mounting plate 201 and the fixed block 3, realizing the removal of the control power supply 1. When it is necessary to install the control power supply 1, the control power supply 1 is inserted and connected with the mounting plate 201. The movement of the transmission block 701 will cause the elastic spring 704 to deform. After releasing the pull rod 702, under the elastic action of the elastic spring 704, the transmission block 701 drives the pull rod 702, the two short rods 703 and the two movable rods 603 to rebound to their original positions. The movement of the two positioning blocks 601 will cause the two return springs 602 to deform. At the same time as the pull rod 702 is released, under the elastic action of the two return springs 602, the two positioning blocks 601 rebound into the interiors of the two plug-in blocks 4, so that the fixed block 3 is fixed with the two plug-in blocks 4, realizing the fixation of the mounting plate 201 and the control power supply 1. The movable door 9 is fixed to the right baffle 202 by bolts to realize the front protection of the control power supply 1. When the control circuit in the control power supply 1 detects an abnormal situation, the power-off device will be triggered. When the control circuit detects an abnormal situation, it will control the action of the power-off device through a signal, so that the electromagnet is attracted and the power supply is cut off.
