How to Choose the Relay to Avoid the Failure?

图片
As a  Power Relay Supplier , share with you. Power Relay 1. What is the problem caused by the coil disconnection of the  Power Relay ? Generally, when most of the relay lines have a disconnection fault, first check whether the disconnection is at the relay pin (prone to the fault of false soldering). Using tweezers to fiddle with each lead, you can quickly find the fault point. 2. The contact loosening and cracking occurred in the relay, mainly due to the loose contact of the relay, the contact cracking or the size deviation is too large. Contact loosening occurs, contact manufacturing, riveting or spot welding is in progress. And also because the material has tolerances, it is determined by the length of each cut. 3. Due to the wide variety of coils used in relays, generally speaking, there are several materials such as outsourcing and non-outsourcing. Therefore, if it is a collision and cross-linking, it may cause disconnection when the coils are separated. So usually th

Do you know the Matters Needing Attention when using Power Relay?

图片
As a  Power Relay Manufacturer , share with you. Power Relay  are commonly used devices in automatic control systems. They are used to connect and disconnect circuits to form automatic control and remote control circuits. Whether it is the core component of a relay signal system or the interface component of an electronic or computer signal system, it plays an important role. The same is true for power relays. Today we will analyze those matters needing attention when using small high-power relays. Power Relay  1. Rated working voltage or rated working current: This refers to the voltage or current required by the coil during high-power operation. The construction of one model is generally the same. In order to adapt to the circuit application of different voltages, a large model usually has multiple rated operating voltages or rated operating currents, and is distinguished by specifications. 2. DC resistance: This refers to the DC resistance of the coil. Some product specif

What is Better to Know When Choosing a Relay?

As a  Power Relay Supplier , share with you. When selecting a relay, you must first understand the technical parameters and characteristics of the relay before it can be put into use. Otherwise, the safety and reliability of the relay will not be guaranteed, which will cause the circuit controlled by the  Power Relay  to be out of control and cause many unnecessary losses in severe cases. 19F Relay The type of relay contact. The contact type of the relay includes single group contact, double group contact, multiple group contact, normally open contact, normally closed contact, etc., when selecting, it should be selected according to the needs of the load circuit. Blindly pursue the selection of multiple sets of contact type relays. Relay power. When the relay is actually used, do not connect the contacts of the relay low power load in parallel to control the high power load circuit. This is because the time it takes for the relay contacts to open to close cannot be exactly the

What are the Application Advantages of Power Relay?

图片
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

What are the Factors Affecting Relay Reliability?

图片
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

What is the Difference Between Signal Relay and Power Relay?

图片
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

What is the Correct Way to use Power Relay?

Generally speaking, product reliability refers to the working reliability of a product, which is defined as: the ability to complete specified functions under specified conditions and within a specified time. It consists of the inherent reliability and reliability of the product. The former is determined by the design and manufacturing process of the product, and the latter is related to the correct use of the user and the pre-sale and after-sales service of the  Power Relay Supplier . Users should pay attention to the following when using item: BS6 Relay 1. Coil use voltage It is better to select the rated voltage according to the coil's use voltage design. If not, please refer to the temperature rise curve for selection. Use of any coil voltage less than the rated operating voltage will affect the operation of the relay. Note that the working voltage of the coil refers to the voltage applied between the coil's lead-out terminals. In particular, the amplifier circuit
