First, the working principle of the power air switch
Compared with the traditional power switch, the household air switch is a controller with a low-voltage distribution network and an electric drive system. The control and protection functions are more prominent during use. In the case of not fully contacting and breaking the circuit, the same It protects against short circuits or loads on electrical equipment. The main function of the power air switch is to automatically cut off the circuit when the working current exceeds the rated current, short circuit, and voltage loss. It can also be used as an infrequent conversion of the line under normal conditions.
Second, what are the power air switch models?
At present, the household uses the DZ series of household air switches (small circuit breakers with leakage protection). The following models/specifications are common: C16, C25, C32, C40, C60, C80, C100, C120, etc., where C indicates tripping. The current, that is, the starting current, for example, C32 indicates that the starting current is 32 amps. Generally, the C500 is required to install the 6500W water heater, and the C40 is required to install the 7500W and 8500W water heaters.
Commonly used in the industry are: DW and DZ for power circuits are divided into 20, 32, 50, 63, 80, 100, 125, 160, 250, 400, 600, 800, 1000... (unit A).
Example: DZ10-100/330Ie=60A
Description: DZ-"automatic" anti-pinyin, 10-design number, 100- is its frame level, 3- indicates the number of poles is three-phase, 3-tripping form (0-no trip unit, 1-hot Trip unit type, 2-electromagnetic trip type, 3-type), 0-with or without auxiliary contacts (0-no auxiliary contacts, 2-with auxiliary contacts), Ie=60A-overcurrent regulation rated current .
Points to note: 1. The rated voltage of the household air switch is greater than or equal to the rated voltage of the line.
2. The rated current of the household air switch and the rated current of the overcurrent release are greater than or equal to the line calculation load current.
The above is the small series for everyone to talk about the working principle of the power air switch and common models, etc., to help you better understand and use the air switch. At the same time, the trading platform also provides you with many types of power air switches, such as People's Electric DZ47-63 series high-breaking miniature circuit breaker (white) air switch, rated voltage 230V and 400V, housing and insulation parts with insulation properties Made of good, impact-resistant, high-flame-retardant material, suitable for AC 50HZ and 60HZ, and rated voltage below 400V, rated current below 63A.
HD Slip Ring is an electromechanical device. It allows the transmission of power and signals from a stationary to a rotating structure. It consists of an electrically conductive rotating ring, with one or more stationary contacts. They are called "stations" or "spokes". Electrical signals (power and/or data) are transmitted through the slip ring. This is done by means of brushes that make contact with the ring.
It is typically used where there is a need to rotate one object relative to another. Especially for passing power and/or signals from the stationary object to the rotating object.
Regarding it's application in conjunction with other equipment, we'll need high-quality production. Oubaibo uses components imported from the United States and high-frequency signal processing. Which has the characteristics of small size, lightweight, good insulation performance, stable transmission, and so on. Its unique design makes it an ideal choice for many applications.
