New Business Online! JRPanel Introduces You Our New Product--Power Transformer

 

Power transformers are one of the main equipment in power plants and substations. The role of the transformer is multi-faceted not only to increase the voltage and send the electric energy to the electricity consumption area, but also to reduce the voltage to the voltage used at all levels to meet the needs of electricity. In short, both step-up and step-down must be completed by a transformer. In the process of transmitting electric energy in the power system, two parts of voltage and power are inevitably lost. When the same power is delivered, the voltage loss is inversely proportional to the voltage, and the power loss is inversely proportional to the square of the voltage. The transformer is used to increase the voltage and reduce the transmission loss.


The transformer is composed of two or more coil windings wound on the same iron core. The windings are connected by alternating magnetic fields and work according to the principle of electromagnetic induction . The installation location of the transformer should be considered to be convenient for operation, maintenance and transportation, and a safe and reliable place should be selected. When using a transformer, the rated capacity of the transformer must be selected reasonably. When the transformer is running at no load, a larger reactive power is required. These reactive power must be supplied by the power supply system. If the transformer capacity is selected too large, it will not only increase the initial investment, but also keep the transformer in no-load or light-load operation for a long time, which will increase the proportion of no-load loss, reduce the power factor, and increase the network loss. This operation is neither economical nor uneconomical. reasonable. If the transformer capacity is too small, the transformer will be overloaded for a long time and the equipment will be easily damaged. Therefore, the rated capacity of the transformer should be selected according to the needs of the electrical load, and should not be too large or too small.


What Is the Main Function of the Power Transformer


1. Transmission and distribution of electrical energy. If it is a step-up transformer, it can send electricity out. If it is a step-down transformer or a distribution transformer, the electric energy can be transmitted or distributed separately;


2. The rated voltage of the primary and secondary side can be changed;


3. The phase angle of the primary and secondary sides can be changed;


What Is the Role of Power Transformer Oil


1) Insulating energy performance


Increase the insulation strength of the components in the transformer. The transformer oil has good insulation strength and fluidity. It can fill all parts of the transformer and any space, expel the air, avoid the contact between the parts and the air, and affect the insulation strength, so that the winding and the winding, the winding and the iron core In between, good insulation is maintained between the winding and the tank shell.


2) Thermal performance


Transformer oil cools the core and windings of the transformer. During the operation of the transformer, the temperature of the oil near the windings and the iron core increases after being heated, the volume expands, and the specific gravity decreases and rises. After being cooled by the cooling device, it enters the bottom of the transformer tank to form an oil circulation. During the cycle, the heat is dissipated to the cooling device, so that the core and windings are cooled.


3) Anti-corrosion performance


Transformer oil can maintain the original chemical and physical properties of insulators (such as wood, etc.), and make metals (such as steel, etc.) play an anti-corrosion effect.

How to Read Circuit Diagrams for Beginners

图片
     👉 https://www.jrpanel.com/R This articles shows how to read circuit diagrams for beginners in electronics. Learn to read electrical and electronic circuit diagrams or schematics. A drawing of an electrical or electronic circuit is known as a circuit diagram, but can also be called a schematic diagram, or just schematic. Circuit or schematic diagrams consist of symbols representing physical components and lines representing wires or electrical conductors. In order to learn how to read a circuit diagram, it is necessary to learn what the schematic symbol of a component looks like. It is also necessary to understand how the components are connected together in the circuit. Battery and Light Bulb Circuit Probably the simplest circuit that can be drawn is one that you may have seen in a school science class: a battery connected to a light bulb as shown below.

What Are the Factors That Affect the Cost of a Membrane Switch?

图片
  "How much does it cost to make a membrane switch? ”  It ’ s a common question we get from customers (and likely one you ’ re pondering if you ’ re reading this article). Unfortunately, the short answer is … it depends.   Since membrane switches are custom-made and include so many variables, it ’ s not feasible to provide a clear-cut estimate without first reviewing the specifications and discussing a few areas. However, based on our experience, three main factors impact the cost of manufacturing a membrane switch.   1.  Circuit design   The printed circuit is the most expensive layer of a membrane switch. Material choices and design (such as the number of traces) can significantly impact the unit ’ s cost. High-quality membrane switches typically use conductive silver ink, which provides the highest conductivity. Depending on application and budget requirements, lower-conductive inks such as carbon, copper, and alloys can be used.   2.   Number of layers and optional features

Points Needing Attention in the Production of Flexible PCB

图片
👉 https://www.jrpanel.com/R The manufacture of flexible PCBs involves several complicated steps, and extreme care must be taken. Some design or manufacturing defects can cause the entire circuit board to fail. During the PCB manufacturing process, please follow the precautions listed below: 1.  Use the right type and quantity of materials to maintain "flexibility". For example, if an application requires a 6-layer rigid-flex PCB that will bend during assembly and then should be kept in a fixed position, the correct type of copper and adhesive must be used. 2.  It is recommended to keep the circuit small. It is better to use a set of smaller circuits rather than a single larger circuit. 3.  It is not a good habit to bend flexible circuits around corners. However, some design situations require bending at the corners. In this case, you can make a gentle bend or use a conical radius bend. 4.  The copper used in the 6-layer rigid-flex board is easy to fall off the substrate. The
