The current range that the headphone socket can withstand

The new photoelectric switches in the headphone socket series usually have the function of automatically avoiding mutual interference, so there is no need to worry about mutual interference. However, when the series of infrared photoelectric switches are placed in several groups parallel to the device, adjacent groups and mutual interference should be avoided. The most effective way to avoid such interference is to insert the projector and receiver, and to widen the group distance when exceeding the group. Of course, using different frequency models is also a good method. The effective way to avoid mutual interference in the series of reflective photoelectric switches is to widen the distance. The earphone socket and the farther the detection interval, the greater the distance should also be. The detailed distance should be determined based on the debugging situation. Of course, models with different operating frequencies can also be used.
Mirror angle influence: When the tested object has luster or encounters a lubricated metal surface, the normal reflectivity is very high and has a similar mirror effect. In this case, the angle between the projector and the detection object device should be adjusted so that its optical axis is not perpendicular to the tested object, thus avoiding misoperation. Sweeping the influence of background objects: When using reflective diffusion type projectors and receivers, sometimes the photoelectric switch may not be able to stably detect due to the detected object being close to the background, or the background being a lubricating object with high reflectivity. Due to the high demand for electricity in winter, some users prefer to plug their computers, heaters, and other appliances into the same multi-purpose socket. While it is very convenient to use, it poses significant safety risks. In terms of electric heating, its starting current is very high. If it is started at the same time as other high-power appliances, the contacts and leads of the socket will be difficult to accept sudden and excessive electrical loads, which can affect each other and damage the appliances themselves, leading to unexpected accidents.
When installing socket devices, the distance between the exposed socket and the air should not be less than 1.8 meters; The concealed socket should be no less than 0.3 meters away from the air. To prevent children from getting electric shock, touching with their fingers, or inserting metal objects into the holes of the power supply, it is necessary to choose a safe socket with a safety shield; The construction wiring requirements for single-phase two eye sockets are: when the holes are arranged horizontally, they are "left zero and right fire", and when arranged vertically, they are "upper fire and lower zero"; The wiring requirement for a single-phase three eye socket is that the grounding hole at the top must be firmly, solidly, and correctly connected to the grounding wire, and must not be disconnected. The remaining two holes of the DC power socket should be wired according to the rule of "left zero and right fire". It is worth noting that the neutral wire and maintenance grounding wire should not be connected incorrectly or together; Refrigerators should use independent, three eye sockets with maintenance grounding. As is well known to headphone socket manufacturers, sockets can only accept a power of 2500W. However, frequent or simultaneous use of high-power appliances such as computers and heaters at home can exceed the safe carrying range of ordinary socket currents, which can easily lead to power outages and even fire accidents. Therefore, high-power appliances must be equipped with 4000W high-power sockets. The socket position is too low. Many households, when installing sockets, feel that being too high hinders aesthetics and may install them in lower shaded areas. This can easily cause water to splash into the socket while mopping the floor, leading to leakage accidents.




According to industry regulations, it is recommended that the distance between exposed sockets and the air should not be less than 1.8 meters; The manufacturer of headphone sockets should install concealed sockets at a distance of no less than 0.3 meters from the air. The sockets in the kitchen and bathroom should be at least 1.5 meters above the air, and the sockets in the air conditioning should be at least 2 meters or more. Misconception 2: Improper installation of socket wires. Xia Dong informed reporters that the power supply wire must use a copper wire cross-section. If you live in an old house, you must replace the original aluminum wire with copper wire. Due to the high oxidation rate of aluminum wire, it is easy to ignite at the joint. A survey has shown that residential buildings using aluminum wires have an electrical fire incidence rate dozens of times higher than copper wires. In addition, many families adopt the method of slotting, burying wires, and laying concealed pipes for the sake of aesthetics. Xia Dong reminds that when wiring, it is necessary to follow the standard of "front line entering switch, zero line entering lamp head", and install leakage maintenance on the socket. Measurement lines for transformers and silicon rectifiers. When measuring the resistance of the main circuit using the voltage drop method, due to the large current passing through the test object, it is enough to damage the metal oxide film on the contact surface, reducing measurement errors and obtaining relatively accurate values. Therefore, the voltage drop method is recommended for measuring the main circuit of switch sockets. The tedious calculation of the micro toggle switch indicates that if the attenuation time constant on the switch socket circuit is set to 45ms, and the A and B phase circuits are connected simultaneously, and the DC weight in A and B phases reaches 0.866, and A phase is delayed by ms, the maximum DC weight in B phase (assuming it happens to be a side phase) can reach 112%. If the attenuation time constant in the switch socket system increases to 60ms, the maximum DC weight in the 6-phase (three-phase) system will reach l15%. In the "separation" experiment, the DC weight at the moment of contact separation is related to the duration of the short circuit, that is, it is related to the opening time of the circuit breaker and the relay maintenance action time.
