Glass plastic

<p>Glass plastic pressure resistance test experience I am on the LED drive power and LED bulb pressure to do some of their own experience and insights, please Paizhuan. LED power playing pressure combining composite and wood railing need to fight how much V How long? How to set the voltage? Many people are used to directly adjust the voltage to reach the number of volts, in fact, this approach is very prone to instant breakdown situation. So our suggestion is that the voltage value should start from 0, quickly adjusted to my own LED driver power supply and LED bulb pressure test some of their own experience and insights, please Paizhuan. 1, LED power playing pressure need to fight how much V long time? Safety standard requirements is 3750V, playing 1 minute.</p><p> Taking into account that some lamps like LED bulb standard is 4000V, so we suggest that the best power also play 4000V, playing 1 minute. 2, how to set the pressure value? Many people are used to directly adjust the voltage to reach the wood plastic composite in Uruguay number of volts, in fact, this approach is very prone to instant breakdown situation. So our suggestion is that the voltage value should start from 0, quickly adjust to the set number of volts. </p><p> withstand voltage meter output terminal how to connect? First, connect the L and N poles of the LED lamp to the input end of the pressure-resistant instrument and then connect the output end of the pressure-proof instrument to the lamp housing (for example, the lamp housing should be wrapped with tin foil). pressure hit but what is the reason? According to our laboratory statistics, most of the pressure resistance but from the transformer, followed by the board creepage distance and electrical clearance is not enough and other reasons. </p><p> Transformers how to fight pressure? If the power withstand voltage beat, however, we must first consider the issue of transformers. When transformer withstands voltage, all primary connections will be short-circuited, and all the secondary connections will be short-circuited. The input and output terminals of the voltage-proof deck spiral staircase waterproof device are connected to primary and secondary, respectively.</p>
