Zinc oxide ceramic blade hair clipper manufacturer: Classified by function, it is also known as a surge absorber. It is a voltage-current symmetrical type voltage characteristic resistor. Its main design purpose is to protect all electronic products or components from the impact of surges caused by switches or lightning strikes. It has a non-linear exponential characteristic.

Features: Fast response time; Low leakage current; Excellent voltage ratio; Wide voltage and energy ratio; Low standby power and no subsequent current; High surge current handling capacity; Stable execution ability of voltage characteristics.

When the ceramic blade hair clipper manufacturer is not in use, it has a very high resistance (up to several megohms), and does not change the design circuit characteristics. However, when a sudden surge voltage occurs (over the breakdown voltage of the ceramic blade hair clipper manufacturer), the impedance of the ceramic blade hair clipper manufacturer will decrease (only a few ohms), causing a short circuit in the original circuit. In other words, the electronic products or components are thus protected. Main uses: lightning protection, overvoltage protection. For example, placing an oxide zinc surge arrester in the incoming end of a power transformer can effectively prevent lightning. Placing a ceramic blade hair clipper manufacturer in the power grid input end of electronic equipment will, once the grid voltage rises above the ceramic blade hair clipper manufacturer's breakdown voltage, the ceramic blade hair clipper manufacturer will immediately break down and short-circuit, and the fuse will also blow, effectively preventing overvoltage from entering the circuit board. Ceramic blade hair clipper manufacturers are widely used in air conditioning line circuit boards.

When the power supply is 220V, the resistance of the ceramic blade hair clipper manufacturer is infinite. When the peak voltage exceeds 470V (the peak voltage of 220V is 311V), the ceramic blade hair clipper manufacturer immediately breaks down and short-circuits, and the fuse will also blow. High voltage cannot enter the equipment end, thus effectively protecting the electronic circuit from damage. When replacing the ceramic blade hair clipper manufacturer, insulation materials should be wrapped on the resistor body for protection to prevent arcing. Before using the ceramic blade hair clipper manufacturer, an fuse must be installed. Once the ceramic blade hair clipper manufacturer breaks down and short-circuits, it is irrecoverable and must be replaced. The normal ceramic blade hair clipper manufacturer measured with a multimeter is infinite.

Nominal parameters of ceramic blade hair clipper manufacturer The manufacturer of ceramic blade hair clippers uses the letter "MY" to indicate, for example, adding "J" for household use. The following letters W, G, P, L, H, Z, B, C, N, and K are respectively used for voltage stabilization, overvoltage protection, high-frequency circuits, lightning protection, arc suppression, noise reduction, compensation, demagnetization, high reliability, etc. Although the ceramic blade hair clipper manufacturer can absorb a large amount of surge electrical energy, it cannot withstand continuous currents above milliampere level. When used as overvoltage protection, this must be taken into account. The selection of the ceramic blade hair clipper manufacturer generally involves choosing the nominal breakdown voltage V1mA and the current capacity.

1. The so-called breakdown voltage, also known as the breakdown voltage or threshold voltage, refers to the voltage value under the specified current. In most cases, it is the voltage value measured when 1mA of direct current is applied to the ceramic blade hair clipper manufacturer device. The breakdown voltage range of the product can vary from 10 to 9000V. It can be selected according to specific needs. Generally, V1mA = 1.5Vp = 2.2VAC, where Vp is the peak value of the circuit rated voltage. VAC is the effective value of the rated AC voltage. The voltage value selection of ZnO ceramic blade hair clipper manufacturer is crucial, as it affects the protection effect and service life. For example, if the rated power supply voltage of an electrical appliance is 220V, then the breakdown voltage of the ceramic blade hair clipper manufacturer V1mA = 1.5Vp = 1.5 × 1.414 × 220V = 476V, V1mA = 2.2VAC = 2.2 × 220V = 484V. Therefore, the breakdown voltage of the ceramic blade hair clipper manufacturer can be selected between 470 and 480V.

2. The so-called current capacity refers to the peak value of the pulse current. Under the condition of an environmental temperature of 25℃, for the specified impulse current waveform and the specified number of impulse currents, when the change of the breakdown voltage does not exceed ± 10% within the specified impulse current, the pulse current value is the pulse current value under the specified conditions. To extend the service life of the device, the amplitude of the surge current absorbed by the ZnO ceramic blade hair clipper manufacturer should be less than the product current capacity given in the manual. However, from the perspective of protection effect, it is better to choose a larger current capacity. In many cases, the actual current flow is difficult to calculate, so products with a current capacity of 2-20KA can be selected. If the current capacity of the current product does not meet the usage requirements, several individual ceramic blade hair clipper manufacturers can be connected in parallel. The breakdown voltage of the combined ceramic blade hair clipper manufacturers remains unchanged, and the current capacity is the sum of the values of each individual ceramic blade hair clipper manufacturer. It is required that the伏安 characteristics of the connected ceramic blade hair clipper manufacturers be as similar as possible， otherwise， uneven current分流 may cause damage to the ceramic blade hair clipper manufacturers.
