For automotive relays that can be energized for a long time, different people have different answers, which tests the understanding of automotive relays. Some people say that they can't be powered for a long time. Long-term power-on will burn out the car relay. Some people say that they can be powered for a long time. The home circuit is our common circuit. If the home circuit is kept energized for a long time, we know that it is a waste of electricity, and secondly it has an impact on the service life of the appliance, which will promote the aging of the circuit. Automotive relays can not be used for long periods of time. This problem is explained in the structure of automotive relays. The contacts of the car relay are divided into two states: normally closed and normally open. What do you think of here? Below we will analyze in detail whether the car relay can be used for a long time.
As an example, the start-up relay can not be powered for a long time, and the light relay can, the start-up relay has large power consumption, large volume, and the coil can not be energized for a long time, which is a short-time work design. The power and volume of the light relay itself are much smaller than the starting relay, and it can work for a long time. If you want to use it for a long time, it is better to switch to the normally closed electric shock of the relay, so you can save power. Ordinary relays can be used for long-term power-on, and relays for special occasions in automobiles are another matter.
Long-term use of automotive relays requires consideration of their working environment, such as temperature, and product quality. The car relay also has its life cycle, so the car should pay attention to maintenance.
