zhz8a type withstand voltage tester can test film breakdown voltage?

Voltage withstand tester is to measure the voltage strength of the instrument, it can be intuitive, accurate, fast, reliable testing of a variety of objects under test breakdown voltage, leakage current and other electrical safety performance indicators, and can be used as a tributary high-voltage source to test the performance of components and the entire machine. zhz8-type voltage withstand testers, according to the requirements of the international safety standards and the design, withstand voltage AC from 0-5KV, the current leakage from AC0-20mA. ZHZ8 type voltage withstand tester is designed according to the requirements of international safety standards, the voltage withstand AC from 0-5KV, the leakage current from AC0-20mA, which is suitable for all kinds of household electrical appliances, power cords, cable wires, transformer terminals, high-voltage plastic and wood electrical appliances, switches, power sockets, motors, dishwashers, dishwashers, centrifugal dewatering machines, microwave ovens, electric ovens, electric kettles, rice cookers, televisions, electric fans, medical treatment, chemical industry, electronic instruments, instrumentation, the whole machine, as well as the strong power system of the safety of withstand voltage and current leakage test, and also an indispensable test of scientific research It is also the indispensable voltage resistance test equipment for laboratory technology supervision department.

Voltage withstand tester in absorbing, digesting the international advanced voltage withstand test on the basis of the actual use of many users in China to improve, improve. zhz8 full digital display voltage withstand tester, test voltage, leakage current test and time are digital display, cut off the current can be according to the different safety standards and different needs of the user to set up continuously and arbitrarily, the function is more rich and practical, and can be reflected in the leakage current display of the body under test, the leakage current can also be used as the leakage current display, the leakage current display of the body under test. Leakage current display reflects the actual value of the leakage current of the body under test and compare the different batches of similar products or different manufacturers of products in the good and bad degree of voltage withstand, to ensure that your product safety performance is foolproof.

The working principle of the voltage withstand tester is through the early together with the insulating part and the charged part of the AC and DC high voltage current applied between the rated value of a certain period of time to detect the instrument insulating materials can withstand the voltage withstand value, because in the daily work of the instrument not only to take into account the impact of the instrument's rated operating voltage, but also to consider the impact of over-voltage within a short period of time is much higher than the rated value of the voltage (such as) Short-circuit or operational errors, etc.), under the action of overvoltage, the structure of the insulating material will be damaged, when more than the maximum value of the insulating material can withstand will occur when the breakdown and lead to abnormal operation of the equipment, but also caused by the operator of the electric shock hazardous to personal safety. Voltage withstand test is by applying a higher than normal voltage several times the value of the product and lasts for a period of time, if the leakage current in the specified time within the prescribed range, the insulation performance is normal, if the breakdown is not normal.

Voltage tester selection needs to be considered in 2 aspects of the factors is its maximum output voltage and maximum alarm current value, the general instrument being tested by the maximum voltage value and alarm current value imposed, voltage tester maximum output voltage value and alarm current value must be greater than the maximum voltage value of the alarm current value to be tested, because the higher the voltage, the higher the current, then the voltage required to boost the power is greater.
