As a  Power Relay Supplier , share with you. Power relay is a device that can generate a jump in the output circuit of one or more electrical appliances when the input quantity (or excitation quantity) meets certain prescribed conditions, and can be used in a direct neutral grounding system. Directional element for zero sequence current protection. It has a wide range of applications. Today we will talk about the application advantages of  Power Relay . 19F Relay Applications in home appliances such as air conditioners often use power relays. In recent years, high-power home appliances have developed rapidly, such as electric water heaters, water dispensers, etc., all use this type of relay. As the three-phase high-power contactors are available in the industry, it is relatively rare. Compared with the commonly used contact capacity of 3-5A, there are also larger models such as the capacity of 7A, and the difference between 10A is not so obvious. In use, its contact action

As a  Power Relay China Supplier , share with you the influencing factors of relay reliability. Power Relay 1. The impact of environment on the reliability of relays: The average time between failures of relays working under GB and SF is the highest, reaching 820,000h, while in the NU environment, it is only 60,000h. 2. The impact of quality level on the reliability of relays: When A1 quality level relays are selected, the average fault interval time can reach 3660000h, while the C level relays are selected with an average fault interval time of 110,000, with a difference of 33 times, which shows the quality level of the relay. The impact on its reliable performance is very large 3. The impact of contact form on the reliability of the relay: The contact form of the relay will also affect its reliability. The reliability of single-throw relays is higher than that of double-throw relays with the same number of blades. Reliability gradually decreases, and the mean time betwee

As a  Power Relay Manufacturer , share with you. The signal relay is generally used for monitoring and protection, and it is widely used in secondary protection circuits of high-voltage distribution cabinets. For example, the temperature of the transformer oil exceeds 85 degrees, and a normally open contact is closed on the temperature monitoring indicator. This contact is connected to the coil of the signal relay, so the signal relay causes the signal relay coil to pull in and the signal relay operates. The "light" sign is dropped, and the high-voltage switch is turned off to unload the transformer, thereby protecting the transformer. However, there are many types of signal relays, some of which are buzzers or flashes as alarm signals. NB901 Relay When the secondary protection circuit is activated, the signal relay is activated. It will accurately inform the person concerned which protection is out of order, and its appearance has a clear activation sign. Power Re
