Time), can be through the first Thermal Cutoffs 30, protective resistance the 50, first display lamp 40, the second rectification two
Pole pipe 80 and the second display lamp 60 reversely end, and this is the situation of normal work, the first display lamp 40
Can send green glow, the second display lamp 60 is the most luminous.Herein, it will be apparent to a skilled person that
In the case of not having thunder and lightning, discharge tube 20 is in the state of disconnection, and electric current will not pass through varistor
10, only in the case of thunder and lightning weather discharge tube 20 is breakdown, electric current just can pass through discharge tube 20 He
Varistor 10.
The feelings fused and electric connection terminal b and the second terminal c is connected are not had at the first Thermal Cutoffs 30
Under condition, discharge tube 20 all can be luminous either with or without breakdown first display lamp 40.
When electric current is from the second terminal c input (that is, when electric current is in negative half-wave), electric current passes through first
Commutation diode 70 flows to the first Thermal Cutoffs 30(now the first Thermal Cutoffs 30 and indicates second
Lamp 60 short circuit, so the second display lamp 60 is the most luminous).Owing to the frequency of alternating current is higher, with people's
From the point of view of naked eyes, the first display lamp 40 is always luminous.
If the first Thermal Cutoffs 30 fuses, (that is, the electric current when electric current inputs from the first terminal a
When being in positive half-wave), circuit breaker, the first display lamp 40 will not be luminous, when electric current is from the second terminal c
During input (that is, when electric current is in negative half-wave), the first display lamp 40 reversely ends the most luminous, and electric current leads to
Cross the first commutation diode 70 and flow to first by the second display lamp 60 and the second commutation diode 80
Terminal a, the second display lamp 60 sends HONGGUANG in this case.Similarly, from the point of view of human eye, the
Two display lamps 60 are always luminous.
