The reason for the tripping of the protector of the sorting machine

1. The leakage switch is damaged or the electrical appliance is grounded and short-circuited, and the zero line on the load side is mixed with the zero line on other circuits.

2. It is caused by unreasonable classification and section protection of the leakage protector switch of the nut sorting machines.


3. Line faults, leakage, short circuit, wiring errors, etc. will cause tripping.


4. The switch is overloaded, and the rated current selection of the switch does not match.


5. The live wire on the load side of the switch is grounded, and the neutral wire on the load side of the leakage switch is grounded, resulting in a trip.



Solution:

1. Select the leakage action current and action time of the leakage switch to be greater than the action current and action time of the upper level leakage switch.

2. Check whether the leakage switch is damaged, and replace it if damaged.

3. Check the insulation of the circuit on the load side of the leakage switch, and check whether the sensitivity of the leakage switch at the upper level is too high.

The concept of embedded computer system

The concept of embedded computer system, in layman's terms, embedded technology is "specialized" computer technology.  embedded computer  ， This special purpose refers to a specific application, such as for network, for communication, for audio, for video, for industrial control, etc. , From an academic point of view, an embedded system is application-centric, based on computer technology, and can be tailored to hardware and software. It is suitable for special-purpose computer systems that have strict requirements on function, reliability, cost, size, and power consumption. Embedded computer system is mainly composed of embedded processor, related supporting hardware, embedded operating system and application software system, etc. It is a "device" that can work independently. Embedded computer generally consists of four parts: embedded microprocessor, peripheral hardware devices, embedded operating system and user's application program. like： What are the f...

At what age can a child ride a scooter?

Scooter, also known as scooter, is a very common children's sports toy.  3 wheel kick scooter At what age can a child ride a scooter? In fact, whether the child can play or not is suitable for scooter, not only the age. Because safety comes first. The speed of scooters is generally faster. Even if they are old enough, but the development of motor ability is delayed, or the ability to understand is not good, they will still be particularly prone to injury. If you only look at age, you can start playing at the age of 2. That is to say, as long as the child walks steadily and can trot, you can buy a scooter for the child. But be sure to pay attention to safety. like： ​How to choose a baby scooter to be safe? ​Buy a three-wheeled scooter or a two-wheeled scooter? ​How old can play children's scooters

Benefits of visual fibre wires

As previously noted, fiber optic cabling has a variety of important characteristics that give it a clear edge over classic metal conductor cable connections in many significant standards. Such as: Data transfer rate and info shift - More aged aluminum details cables, normally copper, provide relatively limited data transfer in comparison to nutritional fibre optics. Copper-type conversation cabling was originally created to transfer tone of voice impulses, which don rsquo;t require nearly as a lot data transfer for bulk data move several modern day programs now desire. Speed - Making use of light pulses as the major supply of details conveyance gives fibre optic cabling a huge speed advantage when compared to other methods of information exchange. Dietary fibre will usually far outstrip the envisioned functionality of even substantial-class (Cat5 or Cat6) copper cables in this connection. Distance - In addition to being super quickly, fibre optic cable connections could also hold th...
