Explosion site 2: aluminum electrolytic capacitor, super pressure explosion
Explosion Scene 3: Super Capacitor Short Circuit
Explosion site 4: high voltage discharge
If the capacitor explodes, its power should not be underestimated. The following is the capacitor explosion test found on the Internet by Yirong.com. I believe that after reading it, it will not be a small capacitor.
So what are the reasons for the capacitor to explode? Let's take a look at it with Xiaobian.
1. Positive and negative poles are reversed
If there is a polarity capacitor, the positive and negative poles are connected to the reverse tantalum capacitor. If the positive and negative poles are connected in reverse, the capacitor is burnt, and the capacitor is exploded.
2, the quality of the capacitor is not off
If the quality of the capacitor is not too good (poor manufacturing process, etc.), it may cause breakdown of the internal components of the capacitor, damage to the insulation of the case, etc., which may cause the explosion of the capacitor (to find the brand capacitor, you can go to the link below to go to: capacitor Search results page).
3, poor sealing and oil leakage
Poor sealing of the assembly casing, causing moisture to enter the interior, may result in a decrease in insulation resistance; or the oil level may drop due to oil leakage, leading to a discharge or component breakdown in the shell direction.
4, internal free and belly
When corona, breakdown discharge and severe freeness occur inside the capacitor, the capacitor will reduce the initial free voltage of the component to the working electric field strength under the action of overvoltage, which will lead to a series of physical, chemical and electrical effects and accelerate the insulation aging. The gas is decomposed to form a vicious cycle, so that the pressure of the casing increases, causing the outer drum of the tank wall to cause an explosion.
5, damage to the insulation of the outer casing
The high-voltage side lead wire of the capacitor is made of thin steel sheet if the manufacturing process is poor. The edge is not flat with burrs or severely bent, and the tip is prone to corona. Corona will cause oil to decompose, the casing expands, and the oil surface drops to cause breakdown. In addition, when the cover is closed, if the welding time is too long at the corner, the internal insulation is burned and oil and gas are generated, so that the voltage is greatly reduced and damaged.
6, with a charge closing caused by capacitor explosion
The live-on of the capacitor bank of any rated voltage is prohibited. Each time the capacitor bank is reclosed, the capacitor must be discharged for 3 minutes with the switch disconnected. Otherwise, the voltage polarity at the moment of closing may be opposite to the polarity of the residual charge on the capacitor and cause an explosion. For this reason, the capacitor bank with a capacity of 160 kvar or more is generally required to be equipped with an automatic trip device without pressure, and the switch of the capacitor bank is not allowed to be equipped with an automatic reclosing.
7, the temperature is too high, causing the capacitor to explode
If the temperature of the capacitor is too high, the electrolyte inside it rapidly vaporizes and expands, breaking through the outer casing and breaking out. The general causes are as follows: 1 The voltage is too high, causing the breakdown of the capacitor, and the current passing through the capacitor increases rapidly in an instant; 2 the ambient temperature is too high, exceeding the allowable operating temperature of the capacitor, causing the electrolyte to boil; 3 the polarity of the capacitor is reversed.
Why do capacitors explode? I believe everyone should be very clear now and know how to prevent it. If you encounter any problems when purchasing capacitors, resistors, inductors, and diodes, you can contact us at any time.
What is a fiber optic slip ring?
A fiber optic slip ring is a device that allows for the transfer of data, power, and signals between two rotating objects. The ring is made up of one or more optical fibers that are used to transmit light signals. These signals can be used to send power, data, or other signals between the two objects. The fiber optic slip ring is a newer technology that has many benefits over traditional slip rings.
How do fiber optic slip rings work?
A fiber optic slip ring is a device that allows electric current and optical signals to pass through a rotating joint. This is often used in applications where it is necessary to transfer data or power between two stationary points while the object rotates. The fiber optic slip ring uses light rather than metal to conduct these signals, which makes it ideal for use in high-speed or hazardous environments.
Types of fiber optic slip rings
When it comes to telecommunications, fiber optics are king. They're the backbone of almost every network today, and they're getting faster and more reliable all the time. That's thanks in part to a technology called fiber optic slip rings.
Advantages of fiber optic slip rings
A fiber optic slip ring is a device used in optical communication. It is a component of many fiber optic networks and it allows for the transmission of data over long distances without losing signal quality. Fiber optic slip rings are also used to improve the performance of other optical systems.
Disadvantages of fiber optic slip rings
Fiber optic slip rings are growing in popularity for rotating applications. Fiber optic slip rings provide many advantages over traditional electrical slip rings, including much smaller size, weight, and power consumption. However, fiber optic slip rings also have a few disadvantages. One disadvantage is that they can be more expensive than traditional electrical slip rings. Additionally, fiber optic cables are more fragile than electrical cables, so they can be more susceptible to damage.
Conclusion: What are the benefits and drawbacks of fiber optic slip rings?
When it comes to fiber optic slip rings, there are both benefits and drawbacks to consider. On the one hand, fiber optic slip rings offer a number of advantages over traditional metal contact slip rings. They are lighter in weight, which makes them easier to install and transport. They also generate less heat, making them safer to use in hazardous environments. Additionally, they provide superior performance in terms of electrical noise and signal integrity.
However, fiber optic slip rings also have some drawbacks. They are more expensive than traditional metal contact slip rings, and they can be more difficult to repair if they malfunction. Additionally, they may not be suitable for some applications due to their limited range of motion.
