2, zinc oxide arrester tester response time tA: The main reaction in the protector of the special protection element action sensitivity, breakdown time, change in a certain period of time depends on the slope of du/dt or di/dt.
3.Maximum longitudinal discharge current of the zinc oxide arrester tester means the maximum surge current peak value to which the protector is tolerated when a standard lightning wave with a waveform of 8/20 μs is applied to each line and the ground.
4. Maximum lateral discharge current of the zinc oxide arrester tester: The maximum surge current peak value to which the protector is tolerated when a standard lightning wave with a waveform of 8/20 μs is applied between the finger and the line.
5. Zinc Oxide Arrester Tester On-line impedance: refers to the sum of loop resistance and inductive reactance through the protector under the nominal voltage Un. Often referred to as "system impedance."
6. The peak discharge current of the zinc oxide arrester tester is divided into two types: rated discharge current Isn and maximum discharge current Imax.
7. Zinc Oxide Arrester Tester Leakage current: Refers to the DC current flowing through the protector under the nominal voltage of 75 or 80.
8. Data transmission rate of zinc oxide arrester tester Vs: how many bits are transmitted in one second, unit: bps; it is the reference value of the lightning protector in the data transmission system. The data transmission rate of the lightning protector depends on the System transmission method.
9. Zinc Oxide Arrester Tester Insertion Loss Ae: The ratio of the voltage before and after the protector is inserted at a given frequency.
10. Zinc Oxide Arrester Tester Return Loss Ar: indicates the proportion of frontier waves reflected at the protection device (reflective point). It is a parameter that directly measures whether the protection device is compatible with the system impedance.
11. Zinc Oxide Arrester Tester Nominal Voltage Un: The rated voltage of the system to be protected corresponds. In the information technology system, this parameter indicates the type of protector that should be selected. It indicates the effective value of the AC or DC voltage.
12. The rated voltage Uc of the zinc oxide arrester tester can be permanently applied to the designated end of the protector without causing changes in the protector characteristics and activating the maximum rms voltage of the protective element.
13. Rated discharge current of the zinc oxide arrester tester Isn: The maximum surge current peak value to which the protector is tolerated when a standard lightning wave with a waveform of 8/20 μs is applied to the protector 10 times.
14. Maximum discharge current of the zinc oxide arrester tester Imax: The maximum surge current peak value to which the protector is tolerated when a standard lightning wave with a waveform of 8/20 μs is applied to the protector for one shot.
Application:The machine is used for series of chemical filament fiber twisting.
1. The machine is adopt servo motor and high strength belt, instead of mechanical cam, convenient maintenance, low power consumption and low noise. The guide rod is controlled by precise guide rail, it realized the precise electronic winding, stepless adjustable to ensure the good forming and unwinding of the bobbin.
2. The electronical system is adopt synchronous motor transducers technology, servo control system adopted to winding. The quality of yarn improved by real-time monitoring process speed.It can not only control the transmission precision,but also reduce the energy consumption, that caused unwinding easily.
3. It is more convenient operation by touch screen.
4. Using 320mm straight bobbin, maximum take-up capacity is 1.8kg.
