(EN) Electronic inverter with protection for discharges produced by malfunctioning in gas discharge or fluorescent lamps at the end of the service life thereof
(ZH) 保护因其使用寿命结束时气体放电灯或荧光灯故障所产生的放电的电子逆变器
Abrégé
(EN)
A full-wave electronic inverter for supplying one or more low-pressure gas discharge or fluorescent lamps, which inverter is protected by a circuit containing a small tubular-core saturable transformer which has the inductive reactance necessary and sufficient for deflecting, from the circuit thereof, the asymmetrical waves which are at a frequency higher than the frequencies stipulated by design and are produced by said lamps at the end of the service life thereof, preventing the inverter from burning out, as occurs with inverters of that type which do not have said circuit which also enables the situation in which, although the inverter is still being connected to the supply circuit, the inverter does not consume energy, even though said lamp or lamps is/are connected to the circuit thereof, until said lamps are replaced with new lamps. This inverter has a starting button which is used to deenergize the inverter each time the latter operates for the first time with new lamps.

用于供应一个或多个低压气体放电灯或荧光灯的全波电子逆变器,该逆变器受包含小管芯饱和变压器的电路保护,该小管芯饱和变压器具有处于比设计所规定的频率高的频率且在其使用寿命结束时由所述灯产生的非对称波偏离其电路必需且充分的感抗,从而防止逆变器烧坏,逆变器烧坏如在不具有还允许以下情形的所述电路的那种类型的逆变器的情况下发生:虽然逆变器仍然连接到电源电路,但是即使所述一个或多个灯连接到其电路,逆变器也不消耗能量,直至所述灯用新灯来替换。该逆变器具有起动按钮,该起动按钮每当用新灯第一次操作时就用于使逆变器失电。
