Switch socket installation requirements
Switches and sockets form part of a complete circuit. If there is no control of the switch socket, then the fixture is just an ornament and cannot be used. Switches and sockets are like bridges in the circuit system, and are essential equipment for the use of electrical appliances and lamps. What principles should we follow for the installation of switch sockets?
The surface-mounted switch affects the home decoration effect, and there are safety hazards, so the surface-mounted switch is gradually eliminated in the decoration. Instead, it is a concealed switch. The concealed switch is generally 1.2~1.5m away from the ground, and the distance from the door frame is generally 10~20cm. The position of the switch should correspond to the position of the lamp position, and the switch installation height in the same room should be the same. After the switch is installed, it must be checked to see if it is short-circuited. The place where the switch is installed is hot. The electrical switch is energized and tested. It can only be used after it has passed the inspection. It must be avoided.
Installation requirements for the socket:
1. The height of the ground mounted socket is generally 1.5--1.8m, and the concealed socket can not be lower than 0.3m. If you have children at home, use a safety socket with a safety cover to prevent children from getting an electric shock or touching the eye socket of the socket with your fingers.
2. The installation wiring of the single-phase two-hole socket is zero when the hole is vertically arranged and zero when the horizontal arrangement is arranged.
3, single-phase three-hole socket installation wiring, the top hole is the grounding hole, must be firmly connected to the grounding wire, must not be connected, the remaining two holes are left zero right fire, we need to pay attention to the neutral line and ground Lines cannot be misconnected or connected.
4. The distance between the strong electric power and the weak electric socket should be kept above 30cm to avoid tightness.
5, high-power electrical appliances such as air conditioners, refrigerators, etc. should use a separate, protective grounding three-hole socket, as well as a three-hole socket in the kitchen hood, rigorously attach the grounding wire to the gas pipe, so it is very easy Caused a fire accident.
People often say that electric tigers, the existence of electricity can not be seen, the harm of electricity is also very large, the maximum voltage that the human body can withstand is 36 volts, the voltage in family life is greater than this number, so that electricity is brought The dangers exist from time to time, so we must do our best to protect the equipment and switches used in household electricity.
Activated Carbon is a very small carbon particle with a large surface area, and there are even smaller holes in the carbon particle-capillary. This capillary has a strong adsorption capacity, because of the large surface area of the carbon particles, it can be in full contact with gas(impurities). When these gases(impurities) touch the capillary, they are adsorbed and act as purifiers. The study of the surface area of activated carbon is very important. The detection data of the specific surface area of activated carbon is only true and reliable by using the BET method. At present, there are many instruments in China that can only be detected by direct comparison methods. Now it is also in China. It was eliminated. At present, multi-point BET method is used for specific surface area testing at home and abroad. The specific surface area measurement standards formulated at home and abroad are based on BET test methods. See the Chinese National Standard(GB/T 19587-2004)-BET principle for the determination of the surface area of solid substances. The specific surface area detection is actually a more time-consuming task. Due to the different adsorption capabilities of samples, the testing of some samples may take a whole day. If the test process is not fully automated, the testers can not leave at all times. And to be highly focused, observe the dashboard, control the knob, and inadvertently lead to the failure of the test process, which will waste a lot of valuable time for the tester. The F-Sorb 2400 ratio surface area tester is an instrument that can truly achieve the BET method detection function(with a direct comparison method). The more important F-Sorb 2400 ratio surface area tester is the only fully automated and intelligent surface area detection device in China so far., Its test results are highly consistent with international standards and have good stability. At the same time, it reduces human error and improves the accuracy of test results.
