Abstract

本实用新型公开了一种补偿电容器专用投入装置,它是电源分别接同步信号电路、预充电电路、控制电路、触发系统电源,上述控制电路接同步信号电路,同步信号电路及预充电电路的输出端投入电容器;所说的同步信号电路是取同步信号电路经整形电路、倒相电路、分离正脉冲电路、启动触发电路连启动隔离电路。本装置可以把合闸涌流限制到零,使电容器直接进入工作电流状态,对设备、对供电线路减少冲击,减除电网公害,延长其使用寿命,提高供电质量。本装置的设计可靠,可确保电压相等时准时投入。本装置所投入的电容的容量越大就越能体现本装置限制涌流的能力,将可控硅电压等级升高后,同样适应高压电容器的投入作业,只适当调整同步触发电路即可。
The utility model discloses a special thrown-in device for a compensating capacitor, which is formed by that a synchronizing signal circuit, a pre-charged circuit, a control circuit and a trigger system power supply are respectively connected with a power supply, wherein the control circuit is connected with the synchronizing signal circuit; the output ends of the synchronizing signal circuit and the pre-charged circuit are thrown in the capacitor. The synchronizing signal circuit is connected with a starting-isolating circuit through a shaping circuit, a negater circuit, a separated positive impulse circuit and a starting-triggering circuit. The utility model can restrict the inrush current in switching-on to zero, so that the capacitor directly goes into the operating current state so as to reduce attack to equipment and supply lines, decrease the public hazard for electric networks, prolong the service life of electric networks, and raise the current supply quality. With a reliable design, the compensating capacitor can ensure the on-time throw-in during equalization of electric voltage. The larger the throw-in capacitance of the capacitor is, the more the capacity for inrush current restricting of this device is embodied. After the voltage level of controllable silicon is raised, the utility model can still adapt the throw-in work of the high-voltage capacitor, just under the condition that the simultaneous triggering circuit is properly adjusted.
