Product Description

General Information

The monostable permanent magnet mechanism is a master of metal materials, mechanics, and power electromagnetic technology application research. The core includes a magnetic core, an excitation coil, a functional spring, and other parts. It has small size and low power consumption (not as good as conventional products). 1/4), with simple structure, fast response speed and no parameter drift (digital), it is the best medium voltage circuit breaker switch control chip technology!

The core material is smelted, forged and precision processed using various formulas such as iron Fe, cobalt Co, manganese Mo and other special processes to achieve the best possible unevenness of the material and highlight its unique high-fidelity magnetic memory characteristics.

Product Features

1. Strong breaking capacity, safe and reliable. The force value of the mechanism is >3500N. The force value matches the best rapid circuit breaker mechanism. It is equipped with a conventional arc extinguishing chamber and has strong breaking capacity.
2. Quick action. The opening time of the switch body is <5ms, the closing and opening time dispersion is <1ms, and it supports multi-stage extreme error protection across the entire line.
3. Ultra-low power consumption. The closing current is <20A, the opening current is <1A, the energy storage capacity is small, less than 30% of traditional products, small size and light weight.
4. Light and simple. It has a simple structure, few parts, is lightweight, reliable and stable.
5. Ultra-wide temperature operation. The new reversible semi-hard magnetic alloy material has raised the demagnetization temperature of traditional products from 100°C to over 300°C, and the long-term magnetic loss demagnetization timeliness is less than 5%.
6. Super wear resistance. The magnetic parts are designed and made of integrated alloy materials, with high overall hardness and strong wear resistance.

Product Structure

The permanent magnet mechanism consists of a moving iron core, a fixed iron core, a permanent magnet, a coil, a driving shaft, and a fixed aluminum plate.

Working Principle

When closing, the energy storage power supply first charges the energy storage capacitor. The closing operation can only be performed when the voltage of the energy storage capacitor is greater than 90%. When closing, the external circuit of the controller provides driving current to the coil and stores the energy stored in the capacitor. Electric energy pours into the permanent magnet coil in a forward direction, and the moving iron core moves in the closing direction under the action of electromagnetic force until it reaches the fully closed position. At this time, the permanent magnet magnetic circuit is closed and the moving iron core is fully attracted, which plays a role in closing and maintaining effect.

When the gate is opened, the controller reversely pours the electric energy stored in the capacitor into the permanent magnet coil. The reverse magnetic field generated by the coil offsets the magnetic field of the permanent magnet. The holding force is smaller than the force of the overtravel spring. Under the action of the opening spring, the moving The iron core is separated from the main body of the mechanism, and the moving iron core drives the transmission shaft to keep the circuit breaker in the open position.
