Redundant excess voltage circuit breaker with a rotational disk and with an added electronic assembly intended to extend a life span of an excess-voltage component |
摘要 |
The invention belongs to the field of overvoltage protection devices intended to protect sensitive electric/electronic devices and assemblies against effects of increased voltages, more precisely to the field of overvoltage protective devices provided with an electronic assembly intended to extend a life span of the basic component and to ensure a higher quality level of protection of electronic devices. The redundant overvoltage circuit breaker with a rotational disk and with an added electronic assembly intended to extend a life span of an overvoltage component is characterized in that it has a gas discharge tube (3) connected in series with a coil (5) and a resistor (4) with a positive thermal characteristic, and a gas discharge tube (6) connected parallel thereto; that a common point of these two branches prevents a route of leakage current via gas discharge tube (3) between the terminals, which can be connected to a line or neutral conductor, via varistor to an earthing point; that there is no leakage current in any of these two branches, since the varistor is galvanically separated between the clamp terminal and the earthing point; that in case of increased current surges the gas discharge tube (6) discharges through a branch of the varistor (7 and 8) into the earthing point; that the varistors (7 and 8) each has its own rotational circuit breaker (9 and 10). |

1. A redundant overvoltage circuit breaker with a rotational disk and with an added electronic assembly for extending a life span of an overvoltage component, characterised in that it has a gas discharge tube (3) connected in series with a coil (5) and a resistor (4) with a positive thermal characteristic, and a gas discharge tube (6) connected parallel to the gas discharge tube (3), the coil (5) and the resistor (4); that a common point of these two branches prevents a route of leakage current via gas discharge tube (3) of one of terminals, which can be connected to a line or neutral conductor, via a varistor to an earthing point; that there is no leakage current in any of these two branches, since the varistor is galvanically separated between the clamp terminal and the earthing point; that in case of increased current surges the gas discharge tube (6) discharges through a branch of the varistor (7 and 8) into the earthing point; that the varistors (7 and 8) each has its own rotational circuit breaker (9 and 10). |
