Common classification of low pressure mine (details) |
1, according to the working principle: (1) switching protector: It works when there is no transient overvoltage presents a high impedance, but once the transient response of lightning over-voltage, low impedance on the mutation, allowing Ray current. When the device is used as such devices are: discharge gap, gas discharge tubes, thyristors and the like. (2) limiting protectors ... |
