Introduction of silicon steel sheet structure of solenoid valve coil

The invention relates to a silicon steel sheet structure of a solenoid valve coil, which comprises a left silicon steel sheet group and a right silicon steel sheet group which are formed by overlapping and punching a plurality of silicon steel sheets from top to bottom, and an upper silicon steel sheet group and a lower silicon steel sheet group which are formed by overlapping and punching a plurality of silicon steel sheets from front to back to form a frame-shaped silicon steel sheet main body, wherein a solenoid valve coil can be arranged in the frame-shaped silicon steel sheet main body, wherein an extension section is arranged on the left and right sides of the upper and lower silicon steel sheets, and the left and right silicon steel sheets Therefore, the effect of reducing magnetic flux and increasing temperature can be achieved.

Operation mode of protective equipment for solenoid valve coil

In the power system, the solenoid valve coil is widely used. In the high-pressure electrical appliances, it is used in the closing circuit and the opening circuit of the high-voltage circuit breaker.

This machine is the most important switching device in the system. Under normal operation, the circuit breaker can turn on and off the load current of the electrical device. When the system has problems, it can reliably disconnect the short-circuit current, avoid the accident extension and ensure the safe operation of the system, so the control of the machine is the most important control operation of the system.

When its control machine gives the command of breaking the brake, the electromagnetic coil of breaking the brake is excited, and the system of starting the valve or the system of the latch, after the release of hydraulic pressure, pushes the main contact of its arc extinguishing chamber to complete the procedure of breaking the brake. When its tripping procedure is completed, its moving contact A1 will be disconnected immediately, and the circuit of the electromagnetic coil of breaking the brake will be disconnected. When it gives the closing instruction, its moving contact A2 will be disconnected immediately.
