Because the voltage transformer is prone to loosening of bolts or rupture of porcelain bushings due to vibration during transportation, it needs to be checked before formal installation to ensure that there is no damage before installation and use. Next, let's take a look at what to check and the steps to install.

Latching refers to "self-locking", which means that after the relay is energized, its state is automatically locked and the circuit is kept connected. Even if the control current is disconnected at this time, its state will not be changed. That is to say, when the power is energized and absorbed, the control current is disconnected, and it remains on until the unlock button is pressed.

Solid-state relay is a new type of non-contact switching device composed of solid-state electronic components. It uses the switching characteristics of electronic components (such as switching triodes, triacs and other semiconductor devices) to achieve non-contact and non-sparking.

Magnetic latching relay is a new type of relay developed in recent years, and it is also an automatic switch. Like other electromagnetic relays, it automatically switches on and off the circuit.

Chip inductors can be divided into low-power inductors and high-power inductors. Chip inductors, low-power inductors are mainly used in frequency selective circuits and oscillating circuits; high-power inductors are mainly used in dc/dc converters, used as energy storage components or lc filtering. There are three types of low-power inductors: wire-wound, multilayer, and high-frequency; high-power inductors are all wire-wound.

Preventive testing is an important link in the operation and maintenance of power equipment, and it is one of the effective programs to ensure the safe operation of power equipment.

A mark (mark) that can distinguish the directionality is often attached to the wire-wound inductor. If the structure of high-power inductors is not completely symmetrical, high-current chip inductor manufacturers will produce characteristic differences in the packaging direction. Therefore, in order to make the product give full play to its due characteristics during use, the product is often marked with a mark to indicate its directionality.

In many electronic application scenarios, people will use step-up transformers, but you may not know the working principle of step-up transformers, so it is very troublesome to choose.

Amorphous strips are mainly used to replace transformer core materials (silicon steel, ferrite), and belong to a new generation of transformer cores. Transformers can be divided into frequency power frequency (50hz or 60hz), intermediate frequency (60hz to 20khz), high frequency (above 20khz) according to frequency.

In many electronic application scenarios, people will use various types of transformers, whether it is a high-frequency transformer or a low-frequency transformer, the manufacturing process is similar. Next, Zou Gong, a senior design engineer from Shenzhen Yingzhe Technology Co., Ltd., will introduce the general production process of transformers.
