How to correct the current relay, the current relay it is to control the electrical system, to ensure the safety and reliability of the electrical system. Current relays are generally used in industry to control the high current load. Here, let me talk about how to choose the current relay correctly, and what key factors to pay attention to when choosing:
1. Select the relay load type:
In our daily life, we choose the electric current relay. First of all, we should understand the load type of the relay. There are two main load types, including DC load and AC load. The circuit is DC with DC load, the circuit is AC with AC load. Choose the right type of relay to better protect the circuit.
2. Rated voltage:
Rated voltage is divided into two kinds, DC voltage and AC voltage. The voltage of the current relay should match the voltage of the required in the electrical system. There are many different types of current relays on the market, and they have different rated voltage range, and you need to choose the right voltage to make the electrical system work better.
3. Load control type:
Common relay load control types in life are single phase and three phase, single phase and three phase current relays have different connection and working principles. Corresponding to the single phase, the three-phase current relay is even more complex, but only by choosing the corresponding control type, it can ensure the safety of the circuit. Current relay switch is usually divided into two types of open and closed.
4. Action time:
The action time is the time when the relay switches quickly when the current works. The reflection time of different relays is different. The shorter the action time, the performance of the relay is better and more stable. Then it can meet the field demand for more electric current.
5. Environmental conditions:
The influence of relay temperature: in life relay should be used in different places, some working environment temperature is high, some temperature is low, and the temperature is too high or too low will lead to the working performance of the relay change. Therefore, when choosing, consider the ambient temperature of the current relay. Ensure that the selected relays work properly within this temperature range.
6. Reliability and longevity:
Relay life: selecting the current relay is to check the life index of the relay and understand its expected service life. Select relays with long life and high reliability to reduce system maintenance costs.
Manufacturer reputation: choose the current relays produced by well-known manufacturers, who usually provide more reliable products with good after-sales service. QIANJI Relay has more than 24 years of experience in relay production, and has accumulated a large number of foreign trade partners, so that your procurement is easier, more secure
7. Dimensions and installation requirements:
Size: Ensure that the selected relays are suitable for the installation space. Being too large or too small may lead to installation difficulties.
Installation requirements: understand the installation requirements of current relay, including connection mode and fixing mode, to ensure correct installation and normal operation.
When selecting the current relay, considering the above factors to ensure that the selected relay can meet the requirements of the system work, and finally consult professional QIANJI engineers when advice. Provide you relay relay solutions. Ask us immediately to get a unique and exclusive quote.
