Use and maintenance of fuses and fuses.resettable fuse datasheet

　　　　1. When the melt melts, it is necessary to carefully analyze the reasons for the melting, which may include:　　(1) Normal fusing due to short circuit fault or overload operation;　　(2) If the melt is used for too long, it may break due to oxidation or high temperature during operation, resulting in changes in the characteristics of the melt;　　(3) There is mechanical damage during the installation of the melt, which reduces its cross-sectional area and causes accidental disconnection during operation.　　2. When replacing the melt, it is required to:　　(1) Before installing a new melt, it is necessary to identify the cause of melt melting. If the cause of melting is not determined, do not replace the melt for trial delivery;　　(2) When replacing a new melt, check whether the rated value of the melt matches the protected equipment;　　(3) When replacing a new melt, it is necessary to check the internal burn condition of the fuse tube. If there are severe burns, the fuse tube should be replac

　　　　1. The fuse is connected in series with the circuit, installed vertically, and installed on each phase line; Fuses are not allowed to be installed on the neutral line of a two phase three wire or three-phase four wire circuit.　　2. The power input terminal of the spiral fuse should be connected to the center point of the base, and the output wire should be connected to the threaded shell; This insurance is used in places with vibrations.　　When the power load is greater than 60A and the lighting or electric heating load (220V) is greater than 100A, a tubular fuse should be used.　　4. The voltage circuit and electrical control circuit of the electricity meter should be equipped with control fuses.　　5. Porcelain plugs shall be made of qualified lead alloy wire or copper wire, and multiple strands of fuse wire shall not be used instead of a large fuse wire.　　6. The fuse should be intact and undamaged, and the contact should be tight and reliable. In conjunction with the maintenance of th

　　　　When an overload occurs, a disposable fuse will blow at once. Although it can provide overcurrent protection, it needs to be replaced. The core part of a conventional fuse is a section of wire, which is heated to the melting point when the current is too high. After the wire melts, the current in the circuit drops to zero. So in some circuits that require complete power outage, or products with higher risk factors such as machinery, it is more suitable to use disposable fuses, which has a higher safety factor when used.　　Both traditional disposable fuses and self restoring fuses can achieve overcurrent circuit protection. Both achieve protection by reacting to the heating phenomenon generated by excessive current in the circuit. Fuses break the current by blowing, while self restoring fuses rely on changing from a low resistance state to a high resistance state to limit the magnitude of the current.　　There are two optional types of self recovery fuses and disposable fuses available

The Channel Dispute of LED and the Impact of Fuses.air conditioner fuse block pull-out replacement

　　　　In the market, we often find that the application of fuses in LED is very extensive. Therefore, the impact of LED development in the industry is also a factor in the development prospects of fuses. The competition for LED channels will inevitably bring about a certain degree of decline or another decline in LED development. Therefore, today, let's take a look at the competition for LED channels.　　The channels in 2022 are very lively. With numerous LED lighting companies entering the market and traditional lighting brands expanding their domestic LED lighting sales channels, even home lighting brands are relying on their distribution points to extend their product lines to the LED lighting series. The competition is becoming increasingly fierce, as if a modern version of the "Spring and Autumn Warring States War" is being staged.　　The LED dispute is largely a channel dispute. Do traditional lighting enterprises have a greater advantage in channels compared to the emerging LED lighti

Application of Self Recovery Fuses in Transformer Protection.solar panel fuse location

　　　　Power transformers are commonly used components in electronic products and are widely used due to their simplicity and ease of manufacture. There are two types of transformers: step-up transformers and step-down transformers (excluding impedance transformers and line matching transformers). They are also called linear transformers because they increase or decrease the original AC voltage proportionally and output it to the load for power supply.　　In application, step-up transformers are mainly used in instruments and meters; For the power supply of electronic products, the majority are actually step-down transformers. Structurally, the transformer is composed of stacked silicon steel sheets and primary coils. The coil is mostly wound with enameled copper wire, and now it is also used with enameled aluminum wire.　　For step-down transformers, their characteristics are: the primary input is 220V, the secondary output is low-voltage, the secondary current is small, the secondary curren
