Current status of the micro toggle switch when it is working

2021/7/16
The miniature toggle switch is turned off under the zero voltage condition, and can also reduce the turn-off loss, but when the MOSFET is turned on under the zero current condition, it cannot reduce the capacitive turn-on loss. Resonant conversion quasi-resonant conversion electrical device is a device that connects and cuts off the circuit. This is a master electrical appliance with a small stroke and instantaneous action. The micro switch is a small contact switch, which can be turned on with a light touch. It is often used in the factory for short-circuit and over-current protection of the large switch.
When the external mechanical force acts on the operating button of the miniature toggle switch, the operating button will move downward, and the spring will be stretched by the hook. When the spring is pulled to a certain length, the moving reed quickly moves downwards, and the contact at the right end of the moving reed turns to contact the normally open contact below. The single-pole switch should be installed on the phase line: the single-pole switch should control the phase line , Cannot be connected to the neutral line. Otherwise, even if the switch is turned off, if the human body touches the phase line and the neutral line, it will also cause an electric shock. If the phase line is grounded, a short circuit or even a fire may occur.
The development of my country's power market for micro-switches represents the development of today's international high-voltage switch market to some extent. The development of the domestic high-voltage switchgear market is mainly due to the extraordinary development of the power industry. West-to-east power transmission, north-south mutual supply, and cross-regional networking have greatly promoted the development of my country's power transmission and distribution equipment industry. When the sinusoidal voltage is output, the power factor of the power grid side (switching output end) of the electronic facilities powered by a single-phase whole group of power sources is only 0.6 to 0.65. Using PFC (power factor calibration) converter, the grid-side power factor can be improved to 0.95¡«0.99, and the output DC THD is less than 20%. It not only manages the harmonic purification of the power grid, but also improves the overall frequency of the power supply. This skill is called active power factor calibration. For APFC single-phase, APFC has developed earlier internationally and the skill is already relatively naive.
