　Tell us about  Power Relay , a device that can be converted in one or more electrical output circuits when input (or excitation) meets certain conditions. It can be used in a neutral point direct grounding system as a directional component for zero sequence current protection. 　　Power Relay The action of the contact can be divided into two parts: contact closure and contact disconnection, that is, the pull-in and release process of the relay, which are cyclically switched at a certain frequency to form a contact opening and closing phenomenon. There are many special physical and chemical phenomena, such as contact contact resistance, contact jitter, and arcing, during contact closure and opening. 　　Principle of action when the contacts are closed Power Relay 　　When the moving contact and the static contact of the relay are in contact with each other, the contact rebound occurs, that is, the uncontrolled gap opening and closing, and the arcing heat generated by the arc and t

In the process of applying Power Relay, there are many problems. So today is mainly about a problem that arises when using relays: Why are relays disconnected frequently? Here are the reasons why the  Automotive Relay Manufacturer  is organized. 1. The load current is greater than the rated switching current of the SSR, which will permanently short the relay. In this case, the SSR with a larger rated current should be used. This is a theoretical statement. In fact, the rated current of the selected relay is not suitable. Simply speaking, when the load is greater than the minimum applicable load, the current can destroy the oxide film on the contact surface, reduce the contact voltage drop, and improve the signal transmission quality; when the load is less than the minimum applicable load, the oxide film and other factors may affect the contact performance of the contact. Although the relay can operate, the signal obtained by the switching is unreliable. Power Relay 2. At t

As an  Automotive Relay Manufacturer , let's talk about the main functions of automotive relays today. 1. Control the strong current with weak current; 2. Reduce the number of manual switches; 3. To achieve the purpose of sequentially controlling the electrical appliances; 4. Protect smaller switches and thinner wires to ensure safe and orderly operation of electrical equipment; 5. Some models use many miniaturized relays with internal resistors/diodes. The miniaturized relay saves assembly space. The relay has a resistor/diode that can reduce or eliminate the 300~500V peak voltage that may appear in the circuit, thus protecting the components in the electronic control system and preventing malfunctions. More typical, such as the starter relay, some people may say: If the positive pole of the power supply is directly connected to one end of the starter, the negative end of the ignition switch is connected to the other end of the starter, the engine can be started. Why

As a  Power Relay Manufacturer , I often meet some customers who say that the quality of your relay is still ok, it is more expensive. Some customers say that I want good quality and cheaper prices. Here, we give everyone a generalization. In fact, the good or bad of Power Relay, 60% is determined by the contacts, reeds, outer casing, thin wire, base, etc. of the relay, and 40% of them are assembled in the relay. Determined in the process. Think about it, if the relay parts are poor, how well the relays are assembled on the production line, and will not make good  PCB Power Relays . Just like a chef, you give him poor raw materials, how good his cooking skills are, and he can't fry good dishes. Therefore, if you have a piece of money and a good quality, it will be more expensive. Power Relay So how do we see the relays are good and bad? If you are interested in researching and taking two different brands, you can see the difference if you study it carefully. Take our relay

What are the relays that can be divided according to the principle? The following  Automotive Relay Manufacturer  will take you to see these ten relays: 1. Signal Relay The signal relay is a commonly used device in the automatic control system. It is generally used to turn the circuit on and off. It releases the control command and reflects the status of the device by dropping the card. After the device returns to normal, the signal is released by the reset signal card. Important originals for automatic control and remote control circuits. 2. Electromagnetic relay A relay that produces a predetermined response by the relative motion of mechanical components under the action of current in the input circuit. It includes DC electromagnetic relay, AC electromagnetic relay, magnetic holding relay, polarization relay, reed relay, energy-saving power relay. 3. Magnetic holding relay The magnetic holding relay adopts the principle of energization to generate a magnetic field, th

The Automotive Relay is subject to different destructive forces depending on where it is installed and functioning in the vehicle. Such as: temperature, humidity, temperature shock, inrush current, etc., if not properly selected and verified, various unexpected failures will occur. Therefore, it should be tested and verified under actual use conditions before application. So where is the Automotive Relay specifically installed? The  Automotive Relay Manufacturer  will give you a brief introduction. Automotive Relay Most of the cars in the Automotive Relay location are the same, and the relays must be installed in the control cabinet or control box. The relay is serially in the main circuit. You can also find it along the circuit. The relay usually has several main contacts, plus two coil contacts, and the contactor is quite similar, but the  Automotive Relay  can generally see it. Contacts, according to this feature you should be able to find. Our company specializes in produc

Automotive Relay Manufacturer  to share the wiring method of automotive relays. The starting control device comprises an electromagnetic switch of the automobile starter and a part of the ignition switch light of the automobile. The structural characteristics of the electromagnetic switch are mainly composed of two parts of an electromagnet mechanism and a motor switch. The electromagnet consists of a stationary core, a suction coil and a holding coil and other component devices. The fixed core fixed and movable core can move axially within the copper sleeve. A movable iron core fixed to the front end of the push rod and the switch contact plate connected to the tip is connected to the fork by an adjusting screw at a core portion and a connecting pin after the event. The outer copper sleeve is mounted with a return spring that resets the core activity and other active parts. The position of the terminal of the electromagnetic switch and the working principle of the electromagnetic

The relay measuring contact resistance uses the resistance file of the universal meter to measure the normally closed contact and the dynamic point resistance, and its resistance value should be 0; while the resistance of the normally open contact and the moving point is infinite. This makes it possible to distinguish which is a normally closed contact and which is a normally open contact.  Power Relay Factory  to share with you. The measuring coil can be used to measure the resistance value of the relay coil by the universal meter R×10 Ω, thereby judging whether the coil has an open circuit. Measure the pull-in voltage and pull-in current to find the adjustable power supply and ammeter, input a set of voltage to the relay, and connect the current meter in the power supply circuit for monitoring. Slowly increase the power supply voltage. When you hear the  Power Relay  sound, record the pull-in voltage and pull-in current. For accuracy, you can try to average and try several times

Most cars can find the relay by simply picking up the hood and finding the relay mounting box. Automotive lighting, wipers, starters, air conditioners, power seats, electric windows and doors, anti-lock devices, suspension controls, audio, etc. use  Automotive Relay , which is one of the most used electronic components in automobiles. Demand exceeds 1 billion. The control relay has two main parts, one is the control system and the other is the controlled system. The reason why the control relay can play a control role is because when a certain signal is input into its control system, such as electric, magnetic, thermal, optical and other physical quantities reach a certain value, the controlled system (also called the output circuit) can be The control quantity is abruptly changed from zero to a certain value, or a certain value is abruptly changed to zero, thereby achieving the functions of controlling, protecting, transmitting and converting information. Controlling large currents
