1. What is the installation method of leakage protector?
The installation method is as follows. But pay attention to the following points:
1. The disconnection "n" wire of the leakage protector cannot be connected to the metal shell.
2. Pay attention to the entrance and exit of the leakage protector.
3. The phase line and N line output by the leakage protector cannot be used separately from other connections.
4. After the installation, turn off the leakage protector and press the test button (T) of the leakage protector to check whether the leakage protector works normally.
2. What brands of anti-leakage protectors are there?
1, Siemens
Siemens was founded in 1847, focusing on electrification, automation and digitalization. It provides transmission solutions, is one of the largest energy-saving and resource-saving suppliers in industrial automation and medical fields, and is in a leading position in shower fields such as imaging equipment and laboratory diagnosis.
2. Zheng Tai
Zhejiang Zheng Tai Electric Co., Ltd. was established in 1997, specializing in the development, production and sales of 100 series of low-voltage electrical products, including power distribution equipment, control equipment, terminal appliances, power appliances and power electronics. Is the first listed company focusing on low-voltage electrical appliances.
3. tailor shop
1920 France is a global energy efficiency management expert and a leading brand in the field of power distribution equipment, providing overall solutions for the energy and infrastructure, construction and residential markets. Leading in energy and infrastructure, industrial process control, building automation, and data centers and networks.
3. What are the skills for purchasing anti-leakage protector?
1. At present, there are different kinds of leakage protectors on the market. When purchasing, we must pay attention to whether the product has passed the national standard GB6829-86 "Leakage Action Protector".
2. The rated voltage of the leakage protector is only 220v and 380v. Household electricity is single-phase, so the voltage is 220v/50Hz. There are three levels of leakage protectors: 2, 3 and 4, and the average family can choose level 2.
3. There are many rated current specifications of the mainstream leakage protector, but the rated current of the overcurrent release is only 10A, 16A, 20A. It should be noted that the AC power supply is 220V, and users can roughly calculate the rated current of the leakage protector according to the current load 5A of 1kw. The rated current value of general overcurrent release can be determined by 0.85 to 0.9 times of the rated current value.
4. Rated leakage current refers to the leakage current value that allows the leakage protector not to work. It is divided into three grades, and the household leakage protector needs to be selected with high sensitivity to ensure personal and property safety.
Four, how to install the leakage protector
The protection type and installation of leakage protector should be adapted to the environmental conditions and use conditions. The first type of mobile electrical equipment includes metal casings and hand-held power tools, electrical equipment installed in harsh places such as damp or strong corrosion, electrical construction machinery and equipment on the construction site, temporary electrical equipment, sockets in hotel rooms and sockets in civil buildings, which have high risk of electric shock, underwater lighting equipment in swimming pools or baths, power cords and electrical equipment installed in water, and electrical medical equipment in hospitals that directly contact with human bodies (except thoracic surgery operating rooms).
That's all that Bian Xiao introduced to you about the earth leakage protector. I hope you can read it carefully, and I hope the above contents can help you.
