In order to ensure the safety of electricity, the current situation is that air-opening has become commonplace in every family. Although we are all using it and even seeing it every day, I don’t think everyone may know everything about air-to- air opening. What types of air-opening are there? Here's what follows my pace, and I'll go back and re-learn about what Air Jump is all about. Here's how it works! Maybe it will help you! What is the open space Air-opening, also known as automatic switch, low-voltage circuit breaker, etc., is a common circuit protector in homes and projects. When the operating current exceeds the rated current, short circuit, voltage loss, etc., the circuit is automatically cut off to achieve the protection function, in addition to the protection function. In addition, it can also be used in conjunction with leaky electrical appliances, measurement, electrical operation and other modular units. In low-voltage power distribution systems, it is often used as a terminal switch or branch switch, replacing the fuses and blade switches commonly used in the past. Air-opening working principle The air-opening internal structure utilizes the bimetallic strip thermal expansion and bending touch-action lever to make the circuit breaker tripping act as a super-load protection. There will be a certain difference in time between overload protection. When a short circuit occurs, current flows through the induction coil and generates a strong magnetic field, which pushes the lever to quickly trip the circuit breaker. In accordance with the different protection, the release can be divided into over-current release and loss of pressure release and other types of tripping, there are three kinds of thermal, electromagnetic and complex tripping. When the line is generally overloaded, the overload current can not cause the electromagnetic release to act, but it can make the heat element generate certain heat, promote the bimetal to be heated upwards, push the lever to release the hook and the buckle, and the main touch Head broken, cut off the power. When a short circuit or severe overload current occurs on the line, the short-circuit current exceeds the instantaneous tripping setting current value, and the electromagnetic release device generates a sufficient suction force to suck the armature and strike the lever, so that the hook moves upwards and rotates the lock seat away from the lock. , The latch will break the three main contacts under the action of the reaction force spring and cut off the power. The tripping mechanism of the switch is a set of linkage devices. When the main contact is closed by the operating mechanism, it is locked by the locking hook at the closing position. If a fault occurs in the circuit, the relevant trip unit will act to disengage the latch hook in the trip mechanism, and the main contact breaks quickly under the action of the release spring.

Air quality Air-opening is a commonly used safe electrical equipment in the home. The quality of air-opening quality is related to the safety of electricity in the home. Therefore, it is necessary to buy a good-quality air-breaker. The following points will help to buy a good-quality air-opening. 1, the most basic method is to look at the weight of open air, in general, high-quality air to open the shell for the flame-retardant PC plastic, the internal use of pure copper wire, the more the number of laps the heavier the quality. 2. Next, look inside the arc-extinguishing cover. The arc-extinguishing cover is used to generate an arc when a circuit is short-circuited and overloaded. If the arc cannot be smoothly extinguished, it will cause a fire. This is very important. The national standard's arc extinguishing chamber consists of Nine iron pieces. 3. Whether the switch surface meter has IEC standards, CCC certification, Great Wall certification, PICC China Insurance Quality Certification, whether there is GB10963 and other signs. 4, as far as possible to select the regular factory production of open, observe the work, shake it if there is a sound, at the same time pay attention to whether there is imitation pseudo-flags and appearance of the font to distinguish. 5, pay attention to the color of the material, the color of the handle, and whether the handle feels good. 6, the coil is electromagnetic induction, if the short-circuit and overload induction coil will pull the release to make it clutch, so the number of turns in the open inner copper coil is better. Open selection The air-opening option is divided into two parts. One part is to learn how to look at the model specifications of the air and the other part is to determine the air- opening specifications that should be used in the home. The letter "D" in the open model number indicates power, and the letter "C" indicates lighting. At present, households use the DZ series of air-opening (miniature circuit breakers with leakage protection), the common specifications are: C16, C25, C32, C40, C60, C80, C100, C120 and other specifications, where C represents the tripping current, ie The take-off current, that is to say when the current in the circuit is greater than this value, the open circuit will automatically trip, and thus play the role of the protection circuit. For example, C32 shows that the starting current is 32 amps. The general installation of 6500W water heaters uses C32, and the installation of 7500W and 8500W water heaters requires the use of C40 air-openings. Under normal circumstances, the principle of open selection: 1, open the rated voltage must be greater than or equal to the rated voltage of the line; 2, empty open rated current and over current release rated current is greater than or equal to the line to calculate the load current.
